Project Descripcion: The main obiectives of the project are to increase food production an some 59.340 ha, stimulate employment in the project area. control damaging floods in rural and urban areas, supplement water supplies for some 300 villages and towns, generate 74 GWh of power which would be fed into the national grid and improve water management in the project area. The project includes: (a) construction of the Kedung Ombo Dam, appurtenant structures, diversion works, a hydro- power plant (28.5 MVA) and associated transmission line (30 km, 150 kV) and three micro-hydropower plants (about 1.8 MVA each) and associated transmission lines (20 kV); (b) improving existing irrigation (34,240 ha) and constructing two new irrigation systems (25,100 ha); (c) establishing a flood warning and water monitoring system for the dam and irrigation operations; and (d) provision of technical assis- tance for: Mi) training in dam construction and safety inspection and in reservoir operations; (ii) design of irrigation works serving 121,300 ha from the Jatigede Dam (West Java); (iii) surveys for updating classification of land for tax purposes to improve cost recovery; (iv) surveys for monitoring resettlement and compensation payments; and (v) studies for soil and water conservation. Although Indonesia is now largely self-sufficient in rice, steady increases in national rice consumption and the very limited scope for expanding the irrigated area on Java make it vital for the country to intensify food production by augmenting dry season water supplies through the construction of multipurpose dams. The increase in cropping intensity thus permitted would also have a substantial impact on raising the incomes of smallholders and landless laborers in an area where more than 60Z of the population has incomes below the absolute poverty line, about a third of farm households are landless, and unemployment is high. The main project risks are delayed land acquisition and inadequate operation and maintenance (O&M) of the irrigation systems. However, land acquisition has already begun and Government has agreed to a schedule and has given assurances on adequate funding for this purpose. Shortfalls in O&M budgets are not expected in view of assurances obtained for adequate funding and Government's willingness to fund O&M costs for irrigation projects from its development budget, and from increased allocation of land tax revenues collected at the local Level.

BACKGROUND General 1.01 The Government of Indonesia (GOI) has requested assistance for the construction of the Kedung Ombo multipurpose dam, one the major water resource developments in the Jratunseluna River Basin in Central Java. The dam will provide irrigation water for (a) 25,100 ha of new 2rrigation systems in the Klambu Kanan (Juana) and Sidorejo (South Crobogan) - areas and 2b) 34,240 ha in the Sedadi (Upper Sedadi) and Klambu Kiri (Lower Sedadi) I irrigation systems which at present have only wet season irrigation. The project will also control flood waters in che upper and lower Serang area, improve drainage and augment domestic and municipal water supplies in che service areas, and generate hydropower. 1.02 The Bank has been deepLy involved in planning and implementing proj- ects in the Jratunseluna Basin since the Irrigation I Project (Cr. 127-IND) in 1968, under which the then largely inoperative Sedadi irrigation syscems were repaired. Extensive tertiary development in the Upper and Lower Sedadi areas was supported under Irrigation Projects VII and IX (Lns. 1268 and 1435-IND). Master plans for the whole Jratunseluna Basin and designs for additional drainage and flood procection works were also prepared under the Irrigation VII Project together with feasibility studies and designs for a dam at Kedung Ombo on the Serang River and related irrigation development. The flood protection works and drainage are being implemented under the Irrigation XIV Project (Ln. 1811-IND), while construction of the dam and related irrigation facilities will be carried out under the proposed project. The proposed project was prepared by PROSIDA (the special project agency responsible for most Bank-assisted projects) which has now been incorporated into the Directorate of Irrigation II in the Directorate General of Water Resources Development (DGWRD), assisted by consultants (Snowy Mountains Engineering Corporation of Australia). The Agricultural and Rural Sector 1.03 GOI's major objectives for the agricultural and rural sector are to: (a) create productive employment to raise incomes of the rural poor; (b) increase domestic food supply, especially rice, to keep pace with rising demand; (c) expand agricultural exports, particularly of smallholder tree crops; and (d) ensure productive, sustainable use of Indonesia's land, water, and natural resources. 1/ An area on the north coast including the Jragung, Tuntang, Serang and Lusi Rivers which feed the coastal plain east of Semarang, the capital of Central Java (Map 18555). 2/ GOI has renamed the irrigation areas.- based on the sources of water. The names in parentheses refer to the names of administrative areas where the irrigation systems are located. 1.04 Food crop production forms 60% of agriculturaL GDP and 18% of total (DP. Rice is the most importanc food crop. Between 1968 and 1982, rice pro- duction grew substantially in response co government interventions, including expansion of the irrigation network, major changes in rice growing technology, and price incentives. Production gains of other major food crops, while not so impressive as those for rice, have exceeded population growth, although some crops, for exampLe corn, are encountering market constraincs. 1.05 GOI's policies in food crop production, combined with the expansion of the COI infrastructure investment program (e.g. INPRES, etc.) and the strong linkages and multiplier effects between agriculcural incomes and other rural industries, have had a substantial impacc on increasing incomes and levels of living in a large portion of the rural areas. They have also resulted in some reduction in the incidence of rural poverty, even though this still remains a major probLem facing GOI. Increases in income have not been uniformly spread, especiaLly to dryland rood crop farmers. in many cases, inadequate infrastructure is also a contributory factor to slow growth in food crop output, and needs to be addressed through further investments in rural roads, etc. 1.06 The Bank, in cooperation with GOI, has undertaken a series of sector studies related to food crop production, the most recent of which are Policy Options and Strategies for Major Food Croos (October 1982, Report 3686-IND) and the Irrigation Sector Review: An Issues Paper (October 1982 and updated in May 1984) which reviewed the irrigation work program and budget included in the GOI Fourth Five-Year Development Plan (Repelita IV) for the period 1984-88. The Irrigation Subsector 1.07 Irrigation and Rice Production. During 1970-83 rice production grew from 13.1 million tons to 23.3 million tons. Production increased at about 4.9% per year during 1970-81, but slowed to 2.2% per year from 1981 to 1983 mainly due to droughts. Rice production increases between 1970 and 1981 resulted from increases in the harvested area (25%) and yield increases (75Z). About 16% of the production growth can be attributed solely to expan- sion and improvement in irrigation, about 9Z is due to improved rice varieties and fertil ,er use, and about 75% is due to the joint interaction of these variables.- 1.08 Rice consumption steadily increased at 4.5% per year between 1970 and 1981, of which 2.3% p.a. was due to population increases and 2.2% p.a. to income, price and other effects. In 1980 and 1981, Indonesia became largely self-sufficient in rice, and rice imports plunged from 2.0 million tons in 1980 to 0.3 million tons in 1982. GOI buffer stocks increased to 2.3 million in 1981. Successive droughts reduced production in 1982 and 1983, forcing Government to import some 1.3 million tons of rice in 1983 and 0.3 million 3/ Source: Indonesia - Policy Options and Strategies for Major Food Crops, Report No. 3686b-IND, April 1984. - 3 - tons in 1984. The 1984 crop is tentatively estimated at 25.5 million tons, and buffer stocks have increased once more to some 3 million tons. It is expected that for most "average rainfall" years rice production will meet demand, provided the present rate of irrigation development is maintained. 1.09 In the future, improved rice variecies and fertilizer use are likely to play a lesser roLe in increasing Indonesia's rice production. The use of high yielding varieties (HYVs) is already high (about 80% of the irrigated and wetland crop) and is unlikely to expand beyond 90X in 1990. Several tradi- tional varieties are preferred for taste and ceremonial reasons, and are better adapced to difficult growing conditions such as saline. flooded or water-short areas. Fertilizer use is also high. particularLi on 'ava where about i35 kg of nitrogen and 50 kg of phosohate per hectare are now applied. There is evidence chat nitrogen applications above this would be -wasted and cause crop iosses due to lodging and greater insect damage. With such already high fertilizer and HYV use, future yield increases will depend primarily on improving the quality of irrigation and water management, and expanding irrigation to exiscing dryland areas. 1.10 Strategy for Water Resource Development. GOI's irrigation sector investments include irrigation works to sustain self-sufficiency in rice; swamp reclamation for transmigration; and river control works to develop multipurpose use of water resources for irrigation, municipal water supply, flood mitigation, and hydropower. The Bank sector work assisted by GOI covering the Repelita IV plan period (1984-88) concluded that the following investment program would be justified: (a) Construction of 0.5 million ha of ongoing rehabilitation, and 0.2 million ha of new irrigation works including medium (sedang) and large-scale (khusus) systems. New rehabilitation projects and tertiary network construction of 0.6 million ha would be pursued, together with 0.27 million ha of new small (kecil), medium (sedang) and large-scale (khusus) irrigation works. Construction of at least two major dams on Java to supply water for irrigation intensifica- tion will be included as part of the program. These irrigation works would enable GOI to maintain self-sufficiency in rice produc- tion, which requires an annual growth rate of 3.5% (harvested area growth of 1.4% and yield growth of 2.1%); (b) Construction of 0.1 million ha of tidal swamp reclamation (gross area), and a further 0.3 million ha of new reclamation works to accomodate 20,000 to 25,000 transmigrant families per year. An additional 0.1 million ha of already settled inland swamp area need rehabilitation and improved water control; and (c) Construction of river control and improvement works (levees, dams, etc.), and volcanic debris control in about 20 river basins throughout the country for more efficient multipurpose use of water. 1.11 Multipurpose Use of Water and Dam Construction Program. Java has three million ha under irrigation (60X of all irrigated areas in Indonesia), and very little scope (about 16,O000 ha) for new irrigation schemes. Basic -4- rehabilication of che Javanese schemes is almost completed. Crop productivity could, however, be further increased through intensive system upgrading co improve operations and facilitate maintenance; construction of better tertiary networks; and augmentation of dry season w.ater supplies from multipurpose storage dams. The increase in cropping intensity thus permitted would have a significant impact on raising the incomes of very small farms (0.1 to 0.3 ha) and the employment of surplus landless labor. 1.12 Water resources must also be developed for meeting municipal supplies, hydropower and flood control. Excensive floods in the i980i'81 and 1982/83 wet seasons caused widespread disruption of road transportation and damage to both agricultural and urban areas (e.z., Semarang in Certral Java). Limited municipal and industriaL water suDpLies for key cities (Jakarta, Semarang, Surabaya. etc.) have sLowed down their development. Since groundwater in these sites is not promising, water storage through dams is the only rationai alternacive to increase water supplies. 1.14 GOI started construction of two dams in late 1982, and has detailed designs for nine others, the construction of which is phased to meet actual requirements. At present, COI places highest priority on the Kedung Ombo Multipurpose Dam Project on Java in view of its major irrigation benefits in an area now largely without dry season water but subject to flooding in the wet season. The proposed dam wouLd also generate power and develop municipal water supplies for major towns in the commuand area (Demak, Grobogan, Pati) once flows are controlled in the Serang River. 1.13 Investment Needs. The indicative irrigation program and related investments in water resources developr*nt are estimated to cost about Rp 4.5 trillion (US$4.1 billion) at current costs (see Table 1.1). About one-third of this amount, equivalent to the foreign exchange cost of foreign-assisted projects, is expected to be financed from external loans. This is somewhat higher than the share (about one-quarter) financed from external loans during Repelita III, due to the assumption that completion of ongoing foreign- assisted projects will be given priority over the next few years. As in the past, the balance of funding will come from the Government's domestic budget. The indicative program is 30% smaller than the planned allocations for irrigation and water management. This is partly due to cutbacks in physical programs, due to the overall resource constraint and the changing rice situation. It also reflects some substantially lower unit costs, based on recent experience with international bids for civil works contracts. During 1984/85 and 1985/86, actual budget allocations were only about 75% of the level required for the indicative program, and .ctual expenditures may be even lower. Therefore, to meet the physical program some further rephasing of investments will probably be necessary. This rephasing might also help smooth the projected bunching of investment costs in 1986/87. 1.15 There are a number of features worth noting in the composition of the indicative investment program: (a) Close to 85Z of the costs are related to ongoing projects, of which 77% are foreign-assisted. New foreign-assisted projects are projected to cost Rp 384 billion while new GOI projects are limited to Rp 293 billion; (b) The major components of the program are for large-scale irrigation expansion (38Z), irrigation rehabilitation (14Z), river improvement (12%), irrigation O&M (7U), 0ood control (7%) and medium-scale irrigation (6Z). However. aew investments show a significant reorientation of priorities, away from large-scale irrigation (11%) and towards flood controL (23%) and swamp programs (15%). '-i These changing priorities also reflect a shift in the regional distribution of investments. Java still accounts for more than one-half of total investment costs. However. among new projects, over 90% are located on the Outer Islands, mainly on Sumacra and on Sulawesi.

Source: Bank Sector Work, 1985 1.16 Major Constraints in irrigation development relate to improving irrigation system operation and maintenance (O&M) and ensuring adequate cost recovery. Current standards of 0&1M of the main systems are frequently inade- quate, though GOI has consistentLy raised the level of funds allocated for such purposes, and has decided in FY84/85 to slow the rate of new irrigation construction and divert development funds to improve O&M standards. BanK assistance in O&M is designed to improve the organization and training of the provincial services which are responsible for all O&M activities and to deve- lop and demonstrate new techniques (Irrigation XVII, La. 2119-IND and Second Provincial Irrigation Development Project, Ln. 2375-2ND). Cost recovery through the IPEDA (land tax) s an efficient mechod of colLection, and links levies to the productive capacitv o- -arm Lands. WhiLe capital cost recovery is less than 10%, this is an equitabie position consisEent with che poverty and small farm sizes of most beneficiaries. However. reclassification of newly irrigated lands and raising of ..ew Land taxes have often been slow because of the lack of coordination within the various agencies. Assurances were therefore obtained from Governmenc that reclassification of Land benefitting from the proposed project and collection of increased IPEDA taxes will be carried ouE in a timeiy manner (para. 6.07). Bank assiscance will also seek to introduce a more direct linkage of IPEDA levies to O&M allocations and to ensure that O&M funds are spent effectively. The Role of the Bank 1.17 Since 1968, the Bank has provided US$1,018 million for irrigation projects in Indonesia. The earliest projects were designed to repair major systems to quickly increase rice output. Later projects provided additional rehabilitation of existing systems, drainage, flood protection, and tertiary networks. The most recent projects include measures to strengthen planning, programming, and budgeting capacity and management information systems (Irrigation XV - Cr. 995 and XVI - Ln. 2118), and to build up the capacity of provincial irrigation services in East Java Province (Irrigation XVII - Ln. 2119), and in eight other provinces (Second Provincial Irrigation Development - Ln. 2375). 1.18 During Repelita IV, the Bank's involvement in the sector will emphasize institution-building and address persistent sectorwide problems such as operation and maintenance standards. Lending will focus on: (a) strengthening of national, and especially provincial, irrigation services, and improving their operation and maintenance performance; and (b) a small number of technically complex projects or projects which present difficult economic choices, or in which Bank participation can mobiLize significant cofinancing. Besides the proposed project, these include the West Tarum Canal for irrigation and the Jakarta water supply, and the Jatigede Multipurpose Dam project. 1.19 Project Performance Audits. The .-first six Bank-assisted irrigation projects have been compLeted. Project Performance Audits have been issued for -7- four of them 4 and a follow-up .mpact Evlluation Reporr on .he first project (Cr. 127-IND) was released in July 1983.-; 1.20 The most serious implementation problems were construction delays and cost overruns. The delays arose because of GOI's then cumbersome local bidding, contracting and fund reLease procedures, and shortages of local funds. Cost overruns were due to additional quantities of work required after detailed design, and increased unic costs due to rapid inflation and construc- tion delays. However, cost increases were more than offset by higher ricef prices, and economic rates of return are expected to exceed 40X. Other prob- lem areas include the need to improve operation and maintenance services (O&M) at provincial leveLs; to provide cechnical and administrative support to water user associations; and to promote efficient water use. These Droblems are recognized in the strategy adopted for Bank assistance (para. 1.18) and have been used in the planning and design of this project. 1.21 Disbursement Performance. Disbursements currentlv run at about 73% of appraisal escimates. Performance has improved (disbursements -vere below 61% in FY82) through more intensive supervision by Residenc Bank staff, accel- erating start-up activities and disbursing against statements of expenditures for small civil works contracts. In addition, consulting service needs are usually agreed with the Bank prior to loan negotiations, and civil works for the first year's construction are usually tendered and contracts negotiated prior to loan effectiveness. Together with other continuing Bank assistance to accelerate contracting procedures and improve the domestic construction industry, these measures appear to be progressively reducing implementation delays. II. THE PROJECT AREA Background and Location 2.01 The proposed Kedung Ombo Multipurpose Dam and Irrigation Project is part of the Jratunseluna basin development and is located in the flood plains of the Serang River and its tributaries, about 75 km east of Semarang on the north coast of Java. In 1971, DGWRD assisted by consultants (NEDECO) prepared a master plan for the development of the water resources of the rivers of the Jratunseluna basin, which, together with later studies, identified the following priority schemes: (a) flood mitigation works (levees, etc.) along the Jragung, Tuntang and Dolok Rivers; (b) rehabilitation of irrigation schemes served by the Jragung, Dolok, and Tuntang; (c) tertiary irrigation network construction in the Tuntang, Jragung, and Sedadi areas; (d) flood protection and drainage in the Lower Serang and the river systems that feed the Serang from Mount Muria, and drainage of the swamp areas in the Juana 4/ Credit 127-END, PPAR Report No. 2047, May 1978.

'Valley; and (e) construction of the Kedung Ombo Dam on the Serang River and the Glapan Barrage on the Tuntang River to improve water supplies for irrigation and for flood mitigation. 2.02 The Bank has been involved in the Jratunseluna basin development through the following projects: Irrigation I (Cr. 127-IND), Irrigation VII (tLn. 1268-IND), Irrigation IX (Ln. 1435-IND), Irrigation XI (Ln. 1579-IND) and Irrigation XIV (Ln. 1811-DID). The irrigation I Project rehabilitated the main irrigation system in tr:e Serang area. Extensive tertiary development in the Sedadi (Upper Sedadi) and Klambu Kiri (Lower Sedadi) areas took place under Irrigation VII and rX, and main and some secondary drainage in the Lower Serang and Juana Valley areas is being improved under Zrrigation :IV. 'fn contrast to the Bank's eariier activities which concentrated on improving the irrigation syscem and flood control, ,he prouosed Kedung Ombo projec. is intended to enhance water availability through construction of a dam on the Serang River in order to ex?and irrigation to the currentLy rainfed areas of Sidorejo (South Grobogan) and Klambu Kanan (Juana Valley) and to the already irrigated Sedadi and Klambu Kiri areas, where the system will be improved (see Table 2.1). This will greatly increase the cropping intensity of the previously rehabilitated irrigation systems and reduce floods.

The project area is comprised of parts of four kabupatens (discricts) - Demak, Kudus, Pati and Grobogan - and 22 kecamatans (subdistricts) with 308 villages. The area is well served by air, rail and road transport, and port faciLities in Semarang. Climate and Soils 2.04 The climate is tropical and monsoonal. Mean annual rainfall is about 2,000 mm, with 85% occurring in the wet season (October-November to April-Hay). Mean monthly evapotranspiration exceeds rainfall in the June- October dry season. Most rainfall is localized, short duration, and of high intensity. This underlies the need for flood protection. drainage and supplementary irrigation co achieve satisfactory Leveis oi oroduction in the flood plains of the Serang aiver system. 2.05 The four project ayeas (Sidorejo, Klambu Kanan, Sedadi and Klambu Kiri) have different soi s buC are ai. suited zo intensive rice cropping and several secondary crops. The Sidorejo irrigation area is a relatively well drained flat river plain ac about 20 m above mean sea level (MSL). Due to the flat grades and Lack of drains, shallow inundation occurs in some locations for up to 24 hours following heavy rain. About 5,000 ha of lower- Lying land is subject Eo inundation by the Serang River flood (every five years), but total crop Loss occurs only on about 250 ha. The soils are predominantly grumosols which are suited for intensive rice growing and for dry season secondary crops. The Klambu Kanan area is located on the very flat alluvial flood plains of the Babalan-Juana River at an elevation of 2-14 m above KSL. These plains were built up rapidly by sediment deposition, due to the construction of the Wilalung diversion structure in 1918 and subsequent diversion of Serang River flows to the Juana Valley. The bulk of the area is subject to regular flooding and poor drainage and is classified as permanent swamp (see Map 18555). Works in progress under che Irrigation XIV project (Loa'n 1811-IND) will have a significant effect in improving and extending the cropping area in Klambu Kanan. The Sedadi and Klambu Kiri areas have alluvial deposits of volcanic origin, well suited to intensive rice cultivation. Existing Irrigation Systems 2.06 A large portion of the lower Serang basin, including Sedadi and Klambu Kiri, is covered by irrigation systems. In the Klambu Kanan area, minor streams are diverted to irrigate small areas scattered along the foot- hills in the wet season. The Sidorejo project area has no irrigation. 2.07 The Sedadi irrigation system (previously known as the Glapan-Sedadi) is the largest in the area. Most of the area receives irrigation water from the Serang River through an intake structure (the Sedadi Weir) constructed in 1886, and remodelled in 1922 and 1976. There are four distinct irrigation service areas. Two form the Sedadi area: (a) Serang (about 6,880 ha), served by the secondary canal from the Sedadi River and a canal from the Tuntang River at Glapan which provides an unreliable supply of excess water from the 6/ Detailed soil surveys have been carried out for all project areas. Tuntang. M4ost of :'.e area receives a fairlv reliable wec season water suppLy, but dry season flows are adequace only for abouc 25Z of the area, and (b) Tuntang-Serang (about 7,030 ha). supplied mainiy from the Sedadi Weir suppLemented with excess water .rom tnie runtang River when avaiiable. An additional pump intake for che main canal was constructed around 1970 at Pondok on the Serang River. slightly upstream of the Wilalung diversion structure, 29.4 km downstream from the Sedadi Weir. The Pondok intake was badly silted up in 1973 and has not been used since. About 70% of the Tuntang-Serang area has a reliable water supply for wet season rice but only 25Z receives water in che dry season. 2.08 The other cwo areas fail in Klambu Kiri: (a) Pelayaran (about 10,560 ha) which recei7es water at the downstream end of the Si canal but is Largely dependent on drainage water from the Tuntang-Serang area, fed into the PeLayaran canal, about 10 km downstream from its junction with Si. SuppLies are generally inadequate, particularly in the drv season, and ase of the drainage return flow from Tuntang-Serang causes poor drainage conditions in part of that area; and (b) Wedung (abouc 9,770 ha), which is supplied from the iower section of the Serang or WuLan Rivers by means of a oumping station con- structed at Karanganyar in 1968. Serious siltation problems and pump operat- ing difficulties hamper a regular water supply. About 75Z of the Klambu Kiri area has wet season irrigation buc only 25% has dry season water. 2.09 The structures of the Sedadi and Klambu Kiri system are, in general, sound but several gates need replacing to receive water released from the dam. Tertiary networks have been designed for the entire area, but have been constructed only in Serang and Tuntang-Serang. ConstructiGn in the lower parts of the Pelayaran and Wedung areas has been postponed until regular flooding is prevented there, following completion of flood protection and drainage works under the Irrigation XIV Project (Ln. 1811-IND). Power 2.10 Two power systems operate in Central Java under the Perusahaan Listrik Negara (PLN, GOI's power authority): the Ketanger system to the west and .the larger Tuntang system in the east. In addition, there are many isolated diesel and a few micro-hydro units. The total installed generating capacity in Central Java in 1984 was about 483 MW, comprising 80 MW (16.6Z) of hydro, 300 MW (62%) oil-fired steam, 84 MW (17.5%) gas turbines and 19 MW (3.9%) of diesel capacity. The total installed capacity has almost doubled since 1979. The total firm capacity is about 250 MW (50%). 2.11 Demand for power in Central Java during 1978-83 increased by 26% a year in peak, and 20% a year in energy, sales. With such dramatic increases, it is expected that gas turbines and steam station capacity will be fully utilized by the late 1980s. Any hydro station with even secondary power would prove to be very economical in saving fuel costs from thermal stations. The power component of the proposed project would help meet some of these require- ments. - LI - Town and Village Water Supplies 2.12 Protected water supplies are available only in the towns of Kudus, Purwodadi, Demak and Pati, but only about 152 of the urban population is served by these supplies. In ruraL areas, the onlv source of water is from springs, wells, rivers and canals, and less than 10% of the rural population has access to a protected water supply. Toward the coast, aLmost the entire domestic water supply is untreated canal or river wacer. which is in short supply and becomes heavily polluted as che dry season progresses. Under the project, domestic, municipal and industrial water wouLd be augmented from the dam to benefit people in the towns of Demak, Grobogan and Pati. Municipal water will be treated at various points along the canais. GOI, assisted by the Asian Development Bank (ADB), is currently identifying Ehe necessary water supply investments, and their construction will be coordinated with this project. Agriculture 2.13 Some 69% of the gross project area of 82,600 ha is under rice or secondary crops and 31X (25,310) is secttlements, dry fields, swamp lands, etc. (Table 2.2). About 48% (27,350 ha) of the rice fields are irrigated and 52% are rainfed wetlands (sawahs). About 50% of the rainfed ricelands are subject to floods from the Serang River, but chey will largely be protected by drain- age and flood mitigation works now being constructed under the Irrigation XIV Project (Ln. 1811-IND). The same project will drain the 2,100 ha of permanent swamps in Klambu Kanan, after which they will be reclaimed. - 12 - Table 2.2: LAND USE SUMMARY Present Sedadi- Klambu Klambu With Land classification Sidorejo Kanan Kiri rotal (X) drainage (%)/a 1.

In Sidorejo, production is entirely rainfed. Cropping intensity is high (265%), mostly in maize and soybeans, but rice yields are low due to rainfed conditions and the lack of irrigation. Klambu Kanan has wet season irrigated rice on some 2,550 ha, and rainfed rice on about 15,300 ha, of which 10,000 ha are affected by floods. The rainfed area will increase to about 17,600 ha as a result of drainage improvements under the Irrigation XIV Project. In the dry season, irrigated rice is planted on about 1,000 ha, and maize and soybean are planted over about half of the wet season cropped area. Klambu Kiri has some 20,400 ha of wet season rice, of which 12,100 ha are irrigated and 8,300 ha are rainfed. Poor drainage on about 60% of the rainfed area is being corrected by the Irrigation XIV Project. At present, dry season rice cropping is possible on only about 500 ha due to the severe shortage of irrigation water. In low drainage areas, half the fields are intercropped with maize and soybean/mungbean, and in the dry season, chili, cucumber and watermelon are grown. The Sedadi area has about 13,9G0 ha of wet season rice, 90% of which is irrigated. Dry season rice is grown on about 6,300 ha, and triple cropping is possible near the Sedadi weir on about 1,400 ha. Maize and soybean are planted on about a third of the area which does not have a second rice crop. - 13 - Farm Size and Land Tenure 2.15 The Agricultural Census in 1983 indicated that farm land was distri- buted among some 87,400 farms in the project area (Table 2.3). Almost 55% of farms are less than 0.5 ha, which in conjunction with the high population den- sity refleccs the pressure on land resources. Farm sizes cend to be smaller in Sidorejo, particularly near the urban center of Purwodadi, -where 63% of farms are below 0.5 ha. Almost 60% of farms are owner-overated. 31% are operated by tenants and only 10% by sharecroppers. In most sharecropping arrangements, the landlord and tenant share total oroduction, inpuc and hired labor costs. The tenant and his family provide their Labor. and the Landlord pays the land tax. Land values and rentals vary considerably according co productivity and demand, and are higher in Sidorejo and Kiambu Kanan (Table 2.4). The low averages for land values recorded for the Sedadi areas reflect the poor water control and limited crop production in Klambu Kiri. rable 2.3: SUMMARY OF FARM SIZE DISTRIBUTION, 1983 (Z) Subproject Sidorejo Sedadi- Klambu Kanan Total Klambu Kiri (X) Less than 0.05 3.0 5.9 4.5 5.0 0.05 - 0.09 5.6 2.9 3.8 3.6 0.10 - 0.24 20.4 14.3 18.1 16.4 0.25 - 0.49 34.2 29.5 27.3 29.8 0.50 - 0.74 19.8 19.5 17.6 19.0 0.75 - 0.99 8.2 8.9 8.6 8.7 1.00 - 1.99 7.8 13.5 14.9 12.9 2.00 - 2.99 0.8 3.4 3.5 3.0 3.00 and greater 0.2 2.1 1.7 1.6 Total Z 100.0 100.0 100.0 100.0 No. 15,485 48,926 22,967 87,378 Source: Derived from (Agricultural Census); 1983 - Preliminary. - 14 - Table 2.4: LAND AND RENTAL VALUES Estimated Land values Estimated rentals Rp million/ha Rp '000/ha/year Average Range Average Range Sidorejo Rainfed 3.0 100 100 Sedadi-Klambu Kiri Irrigated 1.3 0.75-2.5 130 40-200 Rainfed 0.75 0.35-1.5 75 25-125 Klambu Kanan Irrigated 3.8 1.0-6.0 240 75-380 Rainfed 2.8 0.6-6.0 125 30-250 Source: Kecamatan Statistics, 1982. Population 2.16 In 1983, the project area had a predominantly rural population of 570,600 (about 125,000 households), distributed as shown in Table 2.5. The relatively small household size (4.6 persons) and low population growth (1.64Z per annum) are indicative of the impact of the family planning program. The working age group (15-59 years) represents about 54Z of the local population, although 42% of the project area population is under 14 years.

Data f Eor 1982 indicate that agriculture provided employment for about 64Z (209.000) of the total employed workforce of 261,000, or some 37Z of the total population. Of the 87,000 farm households in the project area, some 33,000 consist of landless agricultural laborers. The opportunity for urban employ- ment in the four major towns of Demak, Kudus, Pati and Purwodadi is limited, although the seasonal tobacco industry in Kudus employs some 35,000 people. Health 2.18 Most health problems, as elsewhere in Java, are related to diseases commonly associated with poor nutritional standards and environmentaL sanita- tion. The most common diseases are gastro-enteric and parasitic infections (e.g., hookworm). Of primary concern under the proposed project are the possible effects of project construction of a reservoir and new irrigation systems the incidence of water-borne and zoonetic diseases such as cholera, malaria - and filariasis. The high incidence of malaria in irrigation areas can be reduced by closure and draining of secondary and tertiary canals after the establishment of dry season crops, which breaks the continuous vector breeding cycle. This and other measures will therefore be taken under the project to increase the effectiveness of malaria control programs in the service areas (see para. 3.42(e)). III. THE PROJECT Objectives, Rationale for Bank Involvement and Scope 3.01 The major objectives of the project are to: (a) increase food production on some 59,340 ha through irrigation, and provide additional employment opportunities, (b) control flooding in the upper and lower reaches of the Serang River through construction of a dam which, together with works under the Irrigation XIV Project (Ln. 1811-IND), will protect about 10,000 ha of productive land in Klambu Kanan and 5,000 ha in urban areas; (c) supplement municipal water supplies for about 300 villages and towns in the irrigation area; (d) generate hydropower, mostly secondary power, which will result in fuel savings at existing thermal stations; and (e) improve water management in the project area. 7/ Kantor Statistics, Central Java Provincial Government. 8/ About 0.11-0.5Z of the population in most of the project areas is infected with the dominant form of malaria (plasmodium vivaz), the preferred breeding habitat for the vector being paddy lands. In multi- cropped irrigation areas the infection rate probably exceeds 10X. - 16 - 3.02 The recommended Bank participation is justified since (a) the 3ank is supporting che overall develooment rf the Jratunseluna Basin (para. 1.02) through a series of Loans, and the Kedung Ombo Dam is a key component of this development, (b) the Bank has oiayed a key role in the technical studies and design of the project, and will be needed during implementation to assist GOI to supervise the project, and (c) the oroject supports the sector strategies agreLd with GOI for Bank irrigation assistance. 3.03 The main project components are as follows: (a) Dam and Irrigation Development (i) construction of the Kedung Ombo Dam on the Serang River and appurtenant structures; (ii) construction of a new diversion structure at Sidorejo to supply water for the Sidorejo svstem. and a new diversion barrage at Klambu. with associated suppiy canals for the Klambu Kiri and Klambu Kanan irrigation systems; (iii) construction of two new irrigation systems: (a) the Sidorejo system serving 6,100 ha; and (b) the Klambu Kanan system serving 19,000 ha; (iv) improvements to two existing systems: (a) the Sedadi system of 13,910 ha; and (b) the Klambu Kiri system of 20,330 ha; and (v) provision of supplemental municipal water suppLy for 300 villages and small towns through expansion of the irrigation canal system. (b) Power Development gi) construction of a powerhouse and installation of electrical and mechanical equipment, for a generating capacity of 28.5 MVA; (ii) construction of a 30 km single-circuit transmission line (150 kV) and the substations to connect with the grid at Purwodadi and Tanggung; and (iii) construction of micro-hydro power pLants at the Klambu barrage and the Sidorejo ana Sedadi weirs, including 30 km of 20 kV transmission line. (c) Establishment of a Flood Warning and Water Monitoring Center at Kudus for overall operation of the dam and irrigation systems. (d) Technical Assistance for (i) training in dam construction supervision, dam safety inspection, reservoir operation and water quality management and monitoring; (ii) design of the Jatigede - 17 - irrigation systems; (iii) stucv oi upland soil and -water conserva- tion in the cacchment area of the Jatigede Dam; (iv) surveys for resettlement monitoring and compensation payments; and (v) surveys and assistance for updating maps for reclassixicaEion ror land tax (IPEDA) purposes. Project Details 3.04 The Kedung Ombo Dam site is located on the Serang River near the village of Kedung Ombo and is accessible by a 30 km all-weather road from the town of Purwodadi. The drainage basin is 614 sq km. The selection of the site was decided based on the availabilitv of construction materials and hydrological considerations as the most suitable to regulate che maximum quantity of water (85: of the annual flows) at the lowest cost per cu m of water stored. The Dam wilL be a rockfiiLirandomfill embankment with a central impervious core bounded by filter and gravel transition zones. rhe founda- tions consist of interbedded claystones and sandstones and are considered suitable for a fill type dam. The dam will be of 61 m maximum height and 1,600 m crest length. The total embankment volume will be 6.3 million cubic meters (MCM). The design crest level is Elevation (EL) 96. with a full supply level of EL 90. Minimum operating level is EL 64.5 below which the dead storage is 88 MCM and above which the active storage is 635 MCM. The reservoir surface area at maximum flood level EL 94.2 will be 60.4 sq km. 3.05 The appurtenant structures include: (a) a concrete lined diversion tunnel, 4 m in diameter and 325 m long through the right abutment of the dam, which will discharge 180 cu m/sec during the design diversion flood of a 200- year return period; (b) an ungated service spillway incorporating a 40 m long ogee crest with a discharge capacity of 1,000 cu misec during a 15-day prob- able maximum flood; (c) a 250 m wide emergency spillway incorporating a 2-element fuse plug embankment to prevent overtopping of the dam in the event of an extreme flood (the estimated peak discharge during a 15-day probable maximum flood is 4,540 cu m/sec); (d) a 51.7 m high reinforced concrete intake structure and a 270 m long, 3.8 m diameter pressure conduit; and (e) an irri- gation outlet, branching from the pressure conduit, controlled by a fixed dispersion cone valve with a butterfly guard valve. These and other features are indicated in Table 3.1 (see Annex 3, Table 1 and Figure 1). 3.06 Materials sources for the dam will be as follows: (a) the rockfill for the main cofferdam and upstream shell of the embankment will consist of calcarenite from a source near the town of Juwangi, situated 15 km by a new haul road from the damsite; (b) the downstream shell of the dam will consist of randomfill of fresh claystone with interbedded sandstone, the main source being a borrow area, about 1-1/2 km from the damsite, with the balance from required excavation in the emergency spillway area; (c) the impervious core will be weathered claystone, obtained from the dam abutments, and material removed to expose the foundations; and (d) a 2.5 m thick filter drain con- structed against the downstream boundary of the core, as well as filter blankets and finger drains over the foundations downstream of the core, will consist of processed andesite, brought from rock sources close to the site. - 18 - Table 3.1: FEATURES OF KEDUNC OMBO DAM AND APPURTENANCES 1.

The coffer dam will be constructed in the first Piacement season and will form part of the main body of the dam. A water controi plant will be installed in the intake of the diversion tunnel to allow for irrigation releases to existing areas during dam construction. 3.08 An instrumentation network of piezometers. settlement gauges, extensometers and horizontal movement indicators will be inscalled to monitor the behavior of che dam during and after the construction. The dam .s designed and sized to maximize irrigation, although ic has multipurpose bene- fits. The optimum dam height was decided after nvdroLogicai, geologicai, and soil investigations and simulation studies on reservoir operations. 3.09 Water Requirements were estimated for two rice crops over the entire area and for secondary crops for 302 of the area. The wacer requirements were estimated using the Penman formula and crop factors developed for Java by DGWRD's Directorate of Irrigation II (DOI-II) and the International Rice Research Institute (Philippines). Water requirements needed for the designed dry year (one year in five years) vary from 1,880 mm co 2,023 mm per year for the various areas. The maximum water duties for which canals were designed vary from 1.35 to 1.5 liters per sec per ha (see Table 3.2). 3.10 Reservoir Characteristics and Operation. The reservoir will have a normal maximum operating water surface level (NWSL) of 90 m MSL, and minimum operating level of 64.5 m MSL. When full (at NWSL) the reservoir will inundate 46 sq km (4,600 ha) upstream of the dam. Its normal maximum operat- ing capacity will be 635 million cubic meters (MCM). The dead storage volume is 88 MCM. On the basis of simulation studies covering a 31-year hydrological cycle, the average annual inflow to the reservoir is 796 MCM of which 647 MCM will be released for irrigation, 108 MCM released for dump power to prevent spilling, and 11 MCM for urban water supply, while 10 MCM will spill over the dam (see Chart 26681). The dam thus will regulate 85Z of the upper Serang River flows. The reservoir will be operated to guarantee that sufficient water is available to meet the full water requirement for a cropping intensity of 230Z with a 1% risk during the second rice crop season (50% rice crop loss for one year in 31 years) and a 10Z risk during the secondary crop season (three crops of secondary crops lost in 31 years) (see Chart 26681). 3.11 Releases from the dam will form 34% of total cropwater requirements, with 66Z from rainfall and downstream uncontrolled riverflows (Table 3.2). Riverflows must be forecast and rainfall monitored over the service areas daily to provide flow data for reservoir operations and scheduling of dam water. A telemetered hydro-meteorological network will be installed, linked with a minicomputer operation at a Water Control Center to be established for the project at Kudus. - 20 - Table 3.2: ANNUAL WATER REQUIREMENTS AND -SUPPLY BY SOURCE /a Water Releases from Mam. require- Effective Uncontrolled dam for Net water ments rainfall riverflow irrigation/b balance duties - m (Z) m (X) () mm (Z) lJsec/ha Sidorejo 2,023 1,113 (55) 0 (0) 890 (44) 21 (+1) 1.50 Sedadi 1,918 1,021 (53) 0 (0) 857 (45) 40 (.2) 1.40 KIambu Kiri 1,919 959 (50) 310 (16) 640 (33) 10 (+1) 1.35 Klambu Kanan 1,880 960 (51) 442 (24) 458 (24) 20 (*1) 1.35 Average 1,933 999 (52) 251 (13) 664 (34) 19 (+1) /a One dry year in five years. 7T Water supplied at farm level. 3.12 The power generated is essentially due to irrigation releases, and is incidencal. A totaL of 74 CWh of energy will be generated, of which peak power of 14.6 GWh is about 10 MW for 4 hours daily for 952 of the year. 3.13 The Sidorejo irrigation system will provide irrigation and drainage to a net area of 6,100 ha within a gross area of 9,230 ha. Water will be supplied from the Kedung Ombo Dam, approximately 9 river km downstream through a gated intake in a new diversion weir on the Serang River. In addition to the diversion weir, the project works (see Table 3.3) include 87.3 km of primary and secondary irrigatior canals, 46 km of inspection roads for opera- tion and maintenance of the canaLs, 18 km of secondary drains, and appurtenant structures. The Sidorejo system will be equipped with automated hydrotechnical gates in the main and some secondary canals and flow modules for all other secondary/tertiary canals over 6,100 ha on a pilot basis for improved water management. The irrigation area will be divided into 109 tertiary umits, with an average size of 56 ha net irrigable area. The tertiary facilities will comprise tertiary and quaternary canals and drains and minor structures for up to 8-10 ha lots. Additional access roads of 31 km will be constructed for better farmer access. 3.14 The Klambu Kanan system will supply water to a net irrigable area of 19,000 ha in a gross area of 24,000 ha. Works include the construction of a new barrage at Klambu; 192 km of primary and econdary irrigation canals; 111 km of new and improved secondary drains,9 including some "river training' works; and 107 km of inspection roads for operation and maintenance along the irrigation and drainage canals. The irrigation area will be divided into 321 tertiary units with an average size of 59 ha net irrigable area. Additional service roads (90 km) will also be constructed. 91 88 km of primary drains will be consLc.^ted under Irrigation XIV (Ln. 1811-IND). - 21 - 3.15 improvements to Existing Irrigation Systems. For the Sedadi irrigation area (13,910 ha), water will be supplied from the Sedadi weir which will be upgraded. Capacity of the main Si canal (41 km) (see Map le529) will be increased at the upstream end from 12 to 21 cms to supply the 13,910 ha. The supply from the Tuntang River via the Tl canal will be diverted to supply the Tuntang irrigation systems. One secondary canaL will be expanded. che S2/S16 (10 km) canaL, and most secondary canals (58 km) will have minor adjustments (Table 3.3). Tertiary systems have been completed, but minor adjustments in the structures will be made to accommodate changes in the secondary canal. Main (58 km) and secondary (66 km) drains will be rehabilitation. Additional inspection roads (20.5 km iong) will be constructed (see Annex 3 for details). 3.16 Klambu Kiri will have its main and tertiary canal system upgraded with new tertiaries in 50Z of the Lower area (Wedung). A new (twin) main canal (16 km) parailel to the Si canaL will be constructed from the Klambu barrage (see Map 18529) to provide water for the entire 20,330 ha. The only other supply will be the Sedadi-Pelayaran (7.9 km) secondary canal connecting the main canal to che Pelayaran canal. Adjustments will be made to a further 24 km of main canal to increase its capacity. Major adjustments will be made on the secondary canals (128 km) in the Wedung area and modevate adjustments will be made on canals (41 km) in the Pelayaran area. The main system structures in Wedung and the Pelayaran area require major adjustments or replacement (see Table 3.3). Main drains (97 km) are being upgraded under Ln. 1811-IND while secondary drains (164.5 km) will be constructed under this project. _ 22 - Table 3.3: PROJECT IRRIGATION WORKS MAIN CONSTRUCTION FEATURES /a Rlambu Klambu Items Unit Sidorejo Kanan Sedadi Kiri Area ha 6,100 19,000 13.910 20,330 Canals Main km 13.7 38.1 41.2 47.1/c Secondary km 73.6 154.0 10.0ib 169.2 Tertiary/Quaternary km 366.0 1,140.0 250.0 1,220.O/d Drains Primary km 7.1 88.0/e 58.0/e 97.0/e Secondary km 18.0 111.0 66.07? 164.37'f Roads Service km 31.0 90.0 - 21.2 Inspection km 46.0 107.0 20.5 196.5 Structures (Main System) Turnouts no. 64.0 52.0 21.0/b 145.0 Water control no. 126.0 185.0 9.07T 19.0 Other no. 145.0 1,785.0 302.07T 1,170.0 Tertiary block no. 109.0 321.0 169.0 250.0 Size of tertiary block (average) ha 56.0 59.0 82.0 92.0 /a Does not include all figures for adjustments (See Annex 3 for details). b Construction of 3 km of new canals, major adjustments of 7 km of existing canals and minor adjustments of 58 km of existing canals (Annex 3, Table 2). /c Desilting and increasing the present capacity of 24 km of canal and construction of 23 km of new canal. /d New tertiary system for 9,800 ha in the Wedung area and adjustments to 10,500 ha of existing tertiaries. /e Included in the drainage works under Irrigation XIV. 7T Additional drainage over that undertaken in Irrigation XIV. 3.17 Municipal and domestic water supply will be provided by expanding the capacities of specific canals by an average 0.009 liters per sec per ha in the Sidorejo and Klambu Kanan areas, and by 0.006 liters per sec per ha in the Sedadi and Klambu Kiri areas. Treatment of the incremental water supply will be undertaken by GOI through an ADB-assisted project (see para. 2.12). - 23 - 3.18 New Diversion Structures will consist of the Sidorejo and Klambi barrage/weirs (see Annex 3. TabLe 3 for details). The Sidorejo weir is a aew weir located on the Serang River 9 km from the dam which will divert water for the Sidorejo scheme. The weir is a concrete overflow structure 10 m high and 80 m crest length with a primary canal intake on the left side of the weir. The diversion barrage will be on the Serang River near Klambu. The barrage consists of a crested concrete weir 8 m high and 93 m wide. The left and right irrigation intakes pass through desilting basins; the left intake feeds the new twin main canal to the Klambu Kiri scheme and the right feeds the new main canal to the Klambu Kanan system. 3.19 Hydropower Stations and Transmission Line. The main power station will be located on the left bank at che toe of the dam; this affords the most economical aligwnent and provides no interference with the spillway. Mhe plant wiLl consist of one Kaplan-type turbine with 22.5 MW design power. and a three phase vertical shaft generator, with a power rating of 28.5 MVA. The capacity and unit size of the plant were determined as optimum taking into account the economies of secondary power generation utilizing the high irriga- tion releases and spilLs from the reservoir. The generated power will be stepped up to 150 kV through a switchyard at the powerhouse for transmission to Purwodadi and Tanggung substations, 30 km away via a single circuit trans- mission Line. Also included will be the construction and installation of 3 micro-hydro power stations, 1.8 MVA each, at the Sidorejo and Sedadi weirs and the Klambu barrage, with associated substations and a transmission line 30 km long at 20 kV to Purwodadi. The construction of the micro-hydro will be subject to a detailed feasibility study. 3.20 A Flood Warning and Water Monitoring Center will serve to (a) warn the entire river basin of possible floods in the Serang and Lusi basins; and (b) schedule water to the various irrigation systems in the basin based on the availability of water in the river systems and the inflow to the Kedung Ombo reservoir, and on the rainfall over the irrigation service areas. The construction of the center includes: (a) a master control center at Kudus with a building (1,000 sq n) and facilities including auxiliary power supply; (b) a network of telemetered rainfall and water level stations (100) in the catchment area of the Lusi, Serang and Muria basins; (c) operational communication and computer systems with software for rainfall and river flow analysis, flood forecasting and water scheduling; and (d) a radar computer facility to interface with existing radar at the Bureau of Meteorology and Geophysics in Semarang (for advance warning of rainfall). There will be one supply contractor for che equipment, computers and software, who will install, maintain and operate the system and train the staff for a period of two years after installation. Details of the system are given in Annex 7. 3.21 Technical Assistance for Training will focus on dam construction, dam safety inspection, reservoir operation studies and water quality management and monitoring: (a) Dam Safety Inspection and Construction Training will focus on: (i) the role of the engineer in contract administration and construction supervision, quality control and preparation of construction drawings; (ii) accounting and cost control for contracts; - 24 - (iii) familiarization with a computer-based supervisory control system for construction management; (iv) dam safety inspection techniques: and (v) O&M procedures for the dam. The services of four dam constructionisafety inspection experts (total of 15 man- months) intermittencly over a period of 18 months will be needed to provide; (i) three short courses (3 weeks each) on dam contructioniinspection techniques for 21 staff af the Directorates of Irrigation I, II, and Rivers, and the IHE; (ii) assistance to che tHE to establish and coordinate a dam inspection oreanization composed of experienced staff from the Directorate of Rivers and Directorates of Irrigation I and II; and (iii) assistance to .HE in drafting a seismic zoning and seismic loading code for major hydraulic structures. Fellowships will be provided for 15 DGWRD and IHE staff to train in dam safety inspection techniques ac inter- national institutions such as the U.S. Bureau of Reciamation or the U.S. Army Corps of Engineers. Some special equipment for inspection purposes will be procured (Annex 5). (b) Computer-based Reservoir Operation and Water Resources Analysis Training will be for DGWRD and IHE staff who are heavily involved in physical and mathematical model analysis on use of several generalized operational hydrologic and hydraulic computer software. The type of computer software covers hydrologic water control and reservoir system analysis and water resources planning analysis. Three experts from institutions like the Hydrologic Engineering Center (HEC) of the U.S. Corps of Engineers will train IHE staff to set up some 35 HEC operational software in the IHE computer systems and train the staff to apply the use of these software to their reservoir operating rules, hydrologic and hydraulic problems. The training will be composed of six 3-week intermittent sessions interspersed over 18 months in order to ensure that IHE can apply the HEC software on actual problems faced in their day-to-day operation. Cc) Water Quality Management and Monitoring training will consist of: Ci) on-the-job training of staff with foreign expert inputs of 24 man-months in IHE's Division of Environmental Water Quality (DEWQ) to develop a water quality management plan and monitoring network, to set up a data bank, and to evaluate data; and (ii) formal training for three trainees, 6 man-months each, in telemetry and computer data processing in suitable overseas institutions. Some field and laboratory equipment will be procured. 3.22 Technical Assistance for: (a) Design of Jatigede Irrigation Systems. Detailed designs and bidding documents for the proposed Jatigede Dam in West Java are being prepared with Bank assistance under the Irrigation XVI Project (Ln. 2118-IND). Consultants will be provided under the proposed project to design adjustments to the 121,300 ha of irrigation systems to be served by.-the dam, i.e., the Rentang (89,000 ha), Cilutung (7,600 ha), West Cirebon (6,400 ha), and other (6,000 ha) systems. Designs for new pumped irrigation systems over 12,300 ha in the downstream areas will also be prepared. - 25 - (b) Upland Soil and Water Conservacion in Jatigede Dam Catchment. SpeciaL studies wiLl be undertaken to identify criticai soil erosion areas where gully and sheet erosion Dredominate. Engineering and agroforestrv measures will be designed to ameiiorate erosion and loss of catchment water storage. (c) Resettlement Monitoring. Surveys will be performed biannualiv over the entire dam reservoir area to determine the status of compensation Pavments and to monitor sites where peopie are being resettled. Some sampLe survevs will also be undertaken in transmigration and resetclement areas to determine the welfare of the peopLe aiter resetclement. Cd) IPEDA HaoDing and Land Reclassification. Technical assistance wiil be provided for: (L) remapping iOO,000 ha by aerial photographv to a scale of 1:10,000 for demarcation of village boundaries and individuaL Land holdings and for production of Line maps at a scale of 1:2,500, for each land holding and for the production of registers and coordinate indices for each holding; (b) reclassification of each holding under the current IPEDA reclassification tables to assess new taxes; and (c) upgrading of IPEDA inspection offices, including technical assistance for computerized processing and recording of IPEDA collections. Consulting Services 3.23 Consultants (265 man-months foreign and 385 man-months local) will be recruited by DCWRD's Directorate of Irrigation II (DOI-II) to supervise construction of the dam (see Annex 6). They will prepare working drawings and will be responsible for supervision of dam and powerhouse construction (para. 4.04). GOI wishes to appoint the foreign consultant Snowy Mountains Engineering Corporation (SMEC) which designed the dam and powerhouse as consultants for construction supervision and equipment installation. The proposed contract for SMEC was reviewed during negotiations and appointment of the consultants will be a condition of loan effectiveness. 3.24 An expatriate consultant will be recruited to supervise establish- ment of the Flood Warning and Water Monitoring System (18 man-months) and additional consultants for water quality training (24 man-months). Local and foreign consultants (469 and 165 man-months, respectively) will be recruited to bupervise irrigation system construction to assist the Irrigation Project Office (para. 4.04). Consultants for detailed design of irrigation works, construction supervision of the diversion tunnel and bid evaluation of the dam have been recruited under Loan 1811-IND and have been in place since September 1984 (see Annex 6). 3.25 Consultants (510 man-months; 450 man-months local and 60 man-months foreign) will also be recruited for the Jatigede irrigation designs (para. 3.22) Terms of reference for the designs have been reviewed and agreed by the Bank. The consultants will be recruited in September 1985. - 26 - Status of Project Preparation 3.26 The designs and all major investigations for the main dam and power- house have been completed. Bidding documents have been reviewed by the Bank and found satisfactory. The schedule for tendering the main dam and powerhouse for international comperitive bidding CICB) is: invitations were issued on August 6, 1984 for 19 Drequalified contractors; bids were opened on December 6, 1984; DGWRD' s recommendation for cender award -was on February 28, 1985 and the award will be in .av 1985. A condition of loan effectiveness will be the signing oi the concract -sr dam and powerhouse construction. Designs for che diversion tunnel. base camp and hauL road have been reviewed by the Bank. Their construction is under way by local contractors and will be completed prior zo the contract award for the main dam. These initial works have been fully funded by GOI, and demonstrate GOI's incenc to oroceed with the project. 3.27 Geotecnnical investigation and detailed surveys and designs for the Klambu barrage and all other major irrigation structures and canals have been completed. Detailed designs for secondary and tertiary systems will be completed in stages by the end of 1986. The existing designs and investigations for these systems are to a sufficient standard for computing firm cost estimates. Detailed tender documents and specifications would be available in mid-1986 for calling of tenders for the irrigation works (see Annex 4). Detailed specification and designs for the Flood Monitoring System have been completed, are being reviewed by the Bank, and will be tendered in July 1985. 3.28 Land acquisition for the area (340 ha) around the dam site has been completed and about 300 families have transmigrated. The GOI has firm plans to acquire most of the settled land in the proposed reservoir area by 1987/88. The Governor of Central Java has set up coordinating committees for (a) land acquisition and (b) resettlement. Dam Safety 3.29 A panel of three international dam experts have been recruited, have reviewed design and tender documents for the dam, and have found the designs and investigations satisfactory. This panel will continue to review any design modifications and safety arrangements needed during construction up till 1990. GOI will keep the Bank continually informed of the panel's findings (para. 4.02). Dam safety inspections will be performed by ;HE inspection teams on a routine basis (twice a year or more frequently) after the dam is completed. An assurance was obtained during negotiations that by December 31, 1989 IHE wilL submit for the Bank's review a plan for the proposed dam inspection arrangements, and will carry out such plan as acceptable to the Bank. - 27 - Implementation Schedule 3.30 The implementation schedule for the project is presented in Annex 4. The dam will be compLeted in four years (by early 1989) while the irrigation system construction will be completed in six years (by mid- 1991). The implementation targecs are modest in terms of what has been achieved in dam and irrigation construction in Indonesia. Cost Estimates 3.31 Total project costs are estimated at US$283.1 million (excluding taxes of US$17.2 million) of which US$122.7 million (or 44%) will be foreign exchange. Project costs are expressed in January 1985 prices and at an exchange rate conversion of Rp 1,100 = US$1.00. Unit rates for the irrigation system are based on similar irrigation works in the project area, and for the dam on the lowest bid prices of the ICB tenders which were submitted in December 1984. A 19 i allowance for physical contingencies has been included for the dam, 15Z for the irrigation works, and 5% on consultant services and special equipment. Expected price increases total about 21Z of the base cost and were estimated on the basis of the following inflation rates: for local costs 8% in 1985-90, 5% thereafter; and on foreign costs, 5% in 1985, 7.5Z in 1986, 8% in 1987-90, 5Z thereafter. Details of project costs are given in Annex 1, Table 1 and are sumnarized in Table 3.4. 10/ 20Z for the dam embankment, 15Z for appurtenant structures and and 10% for the power plant. - 28 - Table 3.4: PROJECT COST SUMMARY 2 of Z of Item Local Foreign Total Local Foreign Total foreign total - ltXp billion) - - ( illion)- exchange base cost Civil Works Dan and appartenances 14.6 27.8 40.4 13.3 25.3 38.6 66 - Power stations & transmission 3.1 14.2 17.3 2.8 12.9 15.7 82 - Subtotal 17.7 42.0 59.7 16.1 38.2 54.3 70 26 Irrigation /a Sidorejo 7.7 5.3 13.0 7.0 4.8 11.8 41 - Sedadi 3.3 2.2 5.5 3.1 2.0 5.1 40 - Klambu Kiri 15.4 9.n 24.4 14.0 8.2 22.2 39 - Xlambu Kanan 24.7 15.0 39.7 22.5 13.5 36.0 37 - Xl.ambu Barrage 6.4 7.8 14.2 5.8 7.2 13.0 55 - Subtotal 57.5 39.3 96.8 52.4 35.7 88.1 40 43 Subtotal Civil Works 75.2 81.3 156.5 68.5 73.9 142.4 52 67 Equiwment Office, OM, hydro & training 1.0 4.1 5.1 0.9 3.7 4.6 83 - Telemetry & Water quality 4.2 6.5 10.7 3.8 5.9 9.7 61 - Consultants 8.4 7.0 15.4 7.6 6.4 14.0 46 - Training /b 0.2 1.0 1.2 0.2 0.9 1.1 82 - Administration 14.7 - 14.7 13.4 - 13.4 - Land Acquisition 28.1 - 28.1 25.5 - 25.5 - - Subtotal Equipment & Servicea 56.6 18.6 75.2 51.4 17.9 68.3 26 32 Base Cost 131.8 99.9 231.7 119.9 90.8 210.7 43 100 Physical contingencies/c 16.6 13.5 30.1 15.1 12.3 27.4 45 13 Fxpected price increases/c 28.0 21.6 49.6 25.4 19.6 45.0 44 21 Total Prolect Cost /d 176.4 136.0 311.4 160.4 122.7 283.1 43 134 /a Costs for roads (3Z) and enlarging canals for municipal water supply (0.5Z) are Included in these costs. 7i* Inclades costs of training, consultants and specialized equipment. 7-c See Annex 1, Table 1 footnotes (b) and (c) for contingency assumptions. 7d- Excluding taxes of US$17.2 million on civil works, equipment and services. - 29 - Financing 3.32 The proposed loan of US$156 million (see Annex 1, Table 6) will finance about 60Z of total project costs excluding taxes (US$17.2 million), reserve procurement of vehicles (US$2.1 million) and equipment for the power component (US$21.3 million) wnich will be financed by export credits. The loan will finance the remaining Eoreign exchange costs (US$104.1 million) of the project and US$51.9 million of local costs. GOt wiLl finance the balance of the costs of US$105.8 million (Table 3.5) and is arranging for financing of the power component by export credits to be available by December 1985. The proposed cost sharing arrangements are justified since (a) the project benefits almost entireiy low-income farmers or iandless agricultural laborers (paras. 6.05-6.06), and (b) without external assistance COI would have to slow down implementation to che detriment of economic viabilicy.

Procurement 3.33 Civil Works. The dam and associated works (US$43.7 million) will be constructed through a single contract procured using international competitive bidding (ICB) procedures. The Klambu barrage, Klambu Kanan main canal and Sidorejo weir (US$35.0 million) will be contracted through ICB. A series of about 56 smaller contracts (US$77.0 million) will construct a series of smaller and widely dispersed irrigation works which are unlikely to attract foreign contractors. For these, local competitive bidding (LCB) procedures open to foreign contractors and acceptable to the Bank will be used.

Review of Procurement 3.35 All civil works contracts are reviewed by the Procurement Control Unit (DCWRD) and for contracts Larger than US$500,000. clearance must aLso be obtained from the Ministry of Public Works procurement unit and the SEKNEG - the State Secretariat. The Bank reviews contract evaluation and award through its RSI (Resident Staff. Indonesia) which works closeLy with these agencies on procurement matters. The 3ank has reviewed the contract cocuments for the dam (US$43.7 million) and found them sacis.actory. The Bank will review prior to tendering and award about 24 additional contracts (USS79.0 million) each valued at over USS1.5 miLlion. About 32 other contracts (US$33 million), each valued at less than USS1.5 million, will be reviewed by the Procurement Control Unit, and subsequently by the Bank, on a sample basis after award. The two ICB contracts for equipment (totaLling US$11.2 million) will be reviewed by the Bank prior to tendering. Equipment procured in smalL lots not exceeding US$0.2 million in value will be reviewed after award on a sample basis. Disbursements 3.36 Loan funds will be disbursed against: Category Disbursement (a) Civil works for the dam 74% (b) Civil works for irrigation contracts .4Z (c) Imported equipment and materials 100% of foreign cost (d) Equipment and materials procured locally 65% (e) Locally manufactured goods 95% of ex-factory costs (f) Local and expatriate consultant services, and training costs 100% - 32 - Disbursements will be made against contracts, except for training costs and civil works costs for contracts Less than USS1.5 million -hich wiLl be disbursed against statements of expenditure (Annex 10)._1I rhe proposed allocation of loan proceeds is presented in Annex 1, Table o. rhe disburse- ment profile (Annex 1, Table 7) is projected over a six-year period from September 1985 to June 1991. The profile follows fairly closelv tne Indonesian and Bankwide disbursement profiles for similar works. Loan Closing is expected by December 31, 1991. Accounts, Audits and ReDorting 3.37 Detailed separate accounts and records are kept by DGWRD and PLN for each budget item by project and budget year. Carrv-overs of unspent funds (SIAP) are permitted for two vears. 3ecause SIAPs are permitted, cash books and accounts are not closed until the budeet for the Line item has been fully spent. Project accounts are subiecc-to two audits: (a) by the Inspector General of the Ministry of PubLic Works (MPW), and (b) by the Financial and Development Supervisory Board (BPKP). The work of both auditors has been found to be generally satisfactory on Bank-assisted irrigation projects. Assurances were obtained at negotiations that adequate and separate accounts will be maintained: all contracts, orders and receipts will be kept for at luast one year after loan closing; and independent audits by BPKP of each year's accounts will be submitted to the Bank within nine months of the cLose of each GOI fiscal year. Assurances were also obtained that DGWRD would prepare a Project Completion Report which will be submitted no later than six months after loan closing. Environmental Impact 3.38 Resettlement. Senior environmental specialists and managers from the Institute of Ecology, Padjadjaran University, supervised by international consultants, have been involved since 1981 in identifyir7 the detailed reset- tlement needs of the project, and preparing an environmental impact assessment. 3.39 In 1982, the Government of Central Java set up a coordination committee at the provincial and district levels to coord:nate the transmigra- tion and resettlement of the popuLation to be inundated by the reservoir. The coordination committee is responsible to: (a) carry out `.tailed surveys of the area through the provincial Agraria for purposes of compensation of land and facilities; (b) supervise land transactions; and (c) establish resettle- ment and transmigration implementation teams to coordinate with the peopLe affected. 11/ A revolving fund wilL not be used in the proposed project because of existing prefinancing arrangements with GOI for the irrigation sector. The introduction of such a fund for future projects is being discussed with GOI. - 33 - 3.40 Some 5,390 families (23.380 oeopie) in 2C vilLages wiil be relo- cated. About 12,200 of these people are in che iabor force and 50 are far- mers, 27% are Laborers, 18Z are unempioyed, and 5% have other employmenc. Sample surveys of villages show chat 55% of the people nave incomes below the minimum poverty level. Popuiacion densities vary from 860 to 1,060 people/sa km. In the most recent survey in 1983, 75Z of the famiLies wanted to trans- migrate. Resettlement within the catcnmenc is discouraged because of _ne very high population density and the low productivity of the upland areas. ReDre- sentacives of the affected villages have visited the proposed transmigracion sites in Irian iaya and Bengkulu in Sumatra, and were sacisfied wich Ehe sites. Some 300 families have already cransmigraced. The Proiect Office. in cooperation with the Central Java Provincial Coordinating Committee. has ore- pared a resettlement plan, compensation payments and schedules acceDcable to the Bank (see Table 3.7). Assurances were obtained during negotiations that GOI will provide adequate and timely budgecary resources for compensation pav- ments and will provide the Bank with annual reports on the resectlement, compensation, and welfare of people affected by the reservoir construction commencing December 31, 1985.

The remain- ing 10% have land outside the catchment, or may choose to live with rela- tives. For these people, the Kabupatan Coordinating Development Comittee will give them preference for vocational training, work in local rural works programs, and in the project's civil works construction program (see Annex 8). - 34 - 3.42 Other environmental aspects of the project include: (a) The dam will substantially reduce flooding in the upper Serang River at the junction of the Serang and Lusi. The upper Serang with the modified flows will peak in the dry season. The present flooding downstream of the basin will also be substantially reduced; (b) The Serang and Lusi watersheds are the subject of a recently approved Upland Agriculture and Conservation Project (Ln. 2474-IND) supported by the USAID and the Bank. During negotiations assurances were obtained that the measures taken for catchment procection under this loan will focus on soil and water conservation. in addition, studies will be undertaken by the Directorate General of Land Rehabilitation and Reforestation (DGLRR) for improved soil and water conservation for the proposed Jatigede Dam catchment on che Ci.anuk River; (c) Public health will be improved due to the increased quantity and quality of water available year-round for drinking. Assurances -were obtained during negotiations that a plan for a continuous canal water quality monitoring system will be established by the IHE in consultation with the Provincial Health Services by December 31, 1988 and the system will be in place by June 30, 1991; Cd) There are no archaeological sites or artifacts of any significance in the area to be submerged. Construction of the project is also not expected to adversely affect fauna in the valley; and Ce) Public health authorities, with the cooperation of the Project Office, will intensify malaria control efforts as the irrigation and cropping patterns intensify, since some of the vectors are present and there is some incidence of malaria in the project area. Assurances were obtained at negotiations on appropriate measures for malaria control in the project area. IV. ORGANIZATION AND MANAGEMENT National Level Organization and Management 4.01 DGWRD in the Ministry of PubLic Works will be the principal executing agency for the project responsible for all design and supervisory consulting services and all civil works for the dam, substructure of the powerhouse, major diversion, irrigation and drainage works. PLN, under the Ministry of Mines and Energy, will be responsible for the construction of the superstructure of the powerhouse, electrical and mechanical facilities, equipment installation for the powerhouse, and construction of the transmission line. 4.02 DGWRD will carry out its responsibilities through its Directorate of Irrigation II (DOI-II) (see Chart 26628). A panel of dam experts, established - 35 - to review designs, will continue to review design modifications, safety and economy throughout conscruc:ion. and report to DOI-II (para. 3.29). Assurances were obtained ac aegotiations that the dam panel's comments prior to and during construction regarding safety and economy in construction shail be properLy taken into accounc and that their periodic reports shall be made available to che Bank not :.acer than one month afrer each visit. IHE will organize the inspection teams on a routine basis (three times a year) for a period of five years to perform dam safety inspections. IHE in consultation with the Directorate oi Rizers (DOR), DOI-I and DOI-II will implement the training component of the project. IHE with DOI-II's Project Office will establish the Flood Warning and Water Monitoring Center. 4.03 PLN will implement the power component (see Chart 26718) through its Directorate of Construction, which will manage the consultancs for the power station, and the procurement and instalLation of the electrical and mechanicaL -equipment according to the schedule shown in Annex 4. An assurance to this effect was obtained during negotiations. Field Level Organization and Management 4.04 At the field level. DOI-II's Jratunseluna General Project Office which was established in 1976 in Semarang, will be responsible for the project. To manage day-to-day supervision of construction this office has two Project Offices for the Kedung Ombo Dam and Irrigation (Chart 26629). The Kedung Ombo Dam Project Office is located in the town of Purwodadi, with a site office at the dam location. The Government wishes to continue the services of consultants, SMEC, who will be responsible for supervising construction of the dam at the site (Chart 26630). The Irrigation Project Office has been established at the town of Godong, and will be responsible for supervision of construction of all irrigation works, assisted by local and some foreign consultants (Chart 26631). The present and future staff needs are shown in Table 4.1. An assurance was obtained during negotiations that all staffing requirements will be met by September 30, 1985 for the Dam Project Office and by January 31, 1986 for the Irrigation Project Office, and that vehicles required for implementation will be provided on a timely basis. - 36 - Table 4.1: PROJECT OFFICE STAFF NUMBERS Dam /a Irrigation /b Present Future Present Future Type of Prof. Non-prof.

The Hydropower Project Office will set up a Project Office at the dam site to supervise construction of the powerhouse and the installation of the generator sets. The transmission line contractor will be supervised by the Transmission Office of Central Java in Semarang. 4.06 IHE's Division of Hydrology will establish by June 1986 a Subproject Office within the Jratunseluna General Project Office to implement the Flood Warning and Water Monitoring System. This Subproject Office will supervise the contractors responsible for the installation of telemetry, the water leveL monitoring stations, computers, and software in the Kudus Water Control Center, and will work closely with the Provincial Public Works Office in Semarang, the new Regional (wilayah) office of Pati, and with the Project Offices for the Dam and Irrigation. The Jratunseluna General Project Office will also be responsible to ensure that the Water Control Center at Kudus will be adequately staffed and sufficiently trained by the contractor to manage the water allocation and flood warning operations (para. 4.09). - 37 - 4.07 IHE through its Training Divison will be responsible for all train- ing components in the project. IHE will coordinate with the relevant dir- ectorates in DGWRD to organize training, including the recruitment of experts to teach the dam construction, dam inspection and reservoir operations courses. The dam construction, dam safety and reservoir operations courses will be scheduled for 1986 and 1987. Participants in these courses will be as follows: three each from the iratunseluna Office and the three Project Offices; two each from DOI-I, DOI-II and DOR; and three from tHE. Course material will follow that used by the U.S. Bureau of Reclamation. Project Coordination 4.08 Since agencies from three Ministries at the national, provincial and kabupaten levels are involved in the project, effective coordination of proj- ect activities will be needed at all stages and levels. The following arrangements have been established and are shown on Chart 26718. DGWRD as the principal executing agency wilL coordinate with PLN's central office and the Directorate General of Civil Government and Autonomy (DGCGA) under the Ministry of Home Affairs at the national level. At the field level the Jratunseluna General Project Office will coordinate with the newly established Kedung Ombo Development Coordinating Team under the Office of the Governor of Central Java. The Project Offices for the dam and irrigation will coordinate with the subteams of the Development Coordinating Teams at the kabupaten level for all land and water control and agricultural aspects of the project. The Jratunseluna General Project Office will also coordinate with the Central Java Hydropower and Transmission Project Units of PLN for all aspects of the power component. Operation and Maintenance (O&M) 4.09 Organization for O&M. At present the four project irrigation areas fall in three irrigation regional (wilayah) offices (i.e., Wilayah Pati, Semarang and Surakarta) and four irrigation sectional (seksi) offices. During negotiations assurances were obtained that the Provincial Irrigation Service in Central Java will reorganize its irrigation offices and operations by April 1, 1989 (two years before project completion) as follows: (a) reconfigure the wilayah boundaries so as to follow watershed boundaries of catchments, and, for the project irrigation, all areas will fall under one wilayah office (called the Pati Wilayah) with its headquarters at Kudus (Map 18531); (b) establish a new seksi office for the operation of the dam; (c) establish the four project irrigation areas under three seksi (Serang Bawah, Serang Atas and Pati). The Serang Bawah Seksi will be responsible for the maintenance of all waterways in the lower Serang; - 38 - (d) for the operation of the project, a Water Allocation Committee will be set up composed of the four seksi representatives (Serang Bawah, Serang Atas, Pati and Kedung Ombo). The Committee will meet at least once a week. or more frequently as needed, at Kudus to determine the weekly operating rules for water releases from the dam, and proposed allocations for the various systems; and (e) the Water Control Center at Kudus with all the necessary telemetric, hydrologic and hydraulic information will advise the Water Allocation Committee (WAC) on the possible options for water allocation for the various systems and the releases from the dam. Water allocation will be decided by the WAC. The Water Control Center will have adequately trained staff, who will be in place by April 1, 1989, two years prior to project completion. 4.10 initial Operations and Maintenance (O&M). During construction, the Irrigation Project Office will be responsible for O&M of the new irrigation systems (Klambu Kanan and Sidorejo). O&M of the existing Sedadi and Klambu Kiri systems will remain the responsibiLity of the Central Java Provincial Irrigation Services under the existing Serang Atas and Serang Bawah irrigation section offices. O&M of the tertiaries and quaternaries will be the responsibility of existing water user organizations (see Map 18534) and new ones to be organized in newLy developed areas. After completion of construc- tion, the Project Offices, together with the new Water Control Center at Kudus, will be responsible for O&M of the dam, the Klambu barrage, the new twin canal leading to Klambu Kiri, and the Klambu Kanan and Sidorejo systems for a period of not less than two years. On completion of the power station, PLN will set up its own site office close to the dam site which will be responsible for O&M of the power station. This office will be under PLN's Region XIII Office located at Semarang. PLN's site office will coordinate with the Project Office during the initial period of operation. 4.11 PLN will enter into an agreement with DGWRD and the Provincial Covernment by July 31, 1989, prior to the commissioning of the power station, providing, among other things, operational rules and criteria for utilization of reservoir water for irrigation and power purposes. In the event that any substantial changes in the cropping pattern and/or irrigation releases from the dam are proposed which could affect power generation, DGWRD will consult PLN before such changes are adopted. The Government will inform the Bank of any such proposed changes in sufficient time to give an opportunity to comment. A share (50Z) of the cost of operation and maintenance of the intake of the dam and irrigation/power tunnel will be borne by PLN. PLN will bear the cost of O&M of the powerhouse. Assurances on the above were obtained at negotiations. 4.12 Sustained O&M. Two years after completion of construction, responsibility for O&M of the dam, Klambu barrage, main linking canals, and main system irrigation and drainage for the Klambu Kanan and Sidorejo sub- systems will be turned over to the Provincial Irrigation Services of Central Java (Kedung Ombo, Serang Atas and Pati irrigation section offices, respect- ively). PLN's regional office (Region XIII) will continue to undertake O&M of the power station. Day-to-day operation of the entire irrigation system and - 39 - dam will be controLled by the newLy established Water Control Center's Water Allocation Committee at Kudus. PLN's new office at the dam site will be res- ponsible for the operation of the power station. In addition, the three irrigation seksi will be responsible for day-to-day operations of the three irrigation subsystems up to the tertiary level in the service area. The water users associations will continue to be responsible for OL& of the tertiary and quaternary canals (see Map 18534). New associations will be formed in the newly irrigated areas. Within each irrigation seksi the overall water allocation will be determined by the existing irrigation advisory committees (Panitia Pengairan) at the village levels. 4.13 O&M of the canal inspection roads is carried out in conjunction with the O&U for irrigation. The O&M of the kecamatan and village roads will be performed by the local kabupaten public works offices. 4.14 O&M staffing needs for the various irrigation section offices are indicated in Annex 9, Table 1. O&M cost allocations which should adequately cater for the dam, irrigation and downriver works are US$0.50 million, US$0.89 million, and US$0.34 million, respectiveLy, and are based on existing irriga- tion O&M costs for the Serang Bawah and Atas Section offices for irrigation (see Annex 9, Tables 2 and 3) and on future needs. The average costs per ha for dam, irrigation and downriver works are US$8.40/hatyr, US$15.00/ha/y-r and US$5.8O0haIyr, respectively (see Annex 9. Table 4). An assurance was obtained during negotiations that adequate (as indicated in Annex 9, Table 4) and timely funding and staffing will be provided for 0& (para. 6.09). 4.15 Monitoring and Evaluation (MXE). M&E of the project during and after implementation are important to ensure that project objectives are met. The N&E information on water management will be obtained from telemetric data on every 1,000 ha, available through the water control center at Kudus, and from information gathered by irrigation section and subsection offices and by village water masters. The M&E information on agricultural production, input supply, etc. will be gathered by agricultural extension workers (PPLs, PPMs. etc.) and by village contract farmers and village chiefs. The evalua- tion of the general performance of the irrigation systems would be performed at three levels (the village, kabupaten, and regional (wilayah)) through government-established committees known as "Penitia Pengairan" using the above information. The committees have representatives from local government irrigation, agriculture and district sectional offices. The village, district and regional level committees meet at bimonthly and monthly frequencies. In the existing irrigation areas in Sedadi and Klambu Kiri, these committees are operational and functioning satisfactorily. For the new irrigation areas, GOI legislation requires that committees will be set up prior to the completion of the project. - 40 - V. AGRICULTURAL SERVICES AND PRODUCTION Agricultural Services 5.01 Agricultural support services in the project area are being streng- thened by several Bank-assisted projects and government programs. Ongoing projects include the Second National Agricultural Extension Project (NAEP II, Cr. 996-IND) and the Seeds II Project (Ln. 2066-IND). The main source of inputs for rice production in the four project area districts is the Govern- ment's INMAS program. The INMAS program provides Earmers with subsidized HYV seed, fertilizer and agrochemicals and technical advisory services by field extension staff. Under the program, farmers pay cash for the production inputs which are supplied through the local outlets. Since 1979 a group approach called the INSUS program has also been expanding in the project area. The objective of the INSUS program is to encourage farmer groups in an area of not less than 10 ha, to organize land preparation and planting within specific time limits, to organize water management, to use HYVs and fertilizer, etc. In 1984/85, the INSUS program covered almost 80% of the total planted area in the project districts. 5.02 Crop production intensification methods with use of HYVs and fertilizer inputs are well established in the project area, and during each of the past five years data on fertilizer use and farm surveys indicate that improved technology has been adopted on more than 90% of the area planted with rice. Seeds, fertilizer and pesticides are readily available in the project area, and no supply constraint is expected under the project. Extension services under the Directorate General of Food Crops Agriculture are also adequate. 5.03 Crop Marketing. About 90% of the marketable surplus of rice in the project area is sold by farmers as padi to private traders or millers. The numerous private traders operating in villages in the area provide competition and offer services such as farm collection and drying of produce. About 370 private rice mills and 26 government mills serve the project area subdis- tricts, and almost 200 rice mills are located within the project area bounda- ries. Milling capacity is expected to be adequate for incremental production under the project. Marketing of palawija crops is handled almost entirely by private traders, and well-established marketing channels exist, especially for soybean and mungbean. In order to cater for increased marketing needs as a result of the project, market and village access roads will be constructed under Government's INPRES program. Village Class V roads will be upgraded to Class IV roads in ledadi/Klambu Kiri (57 km); Klambu Kanan (10 km); and Sidorejo (11 km).1 New farm-to-market roads will be constructed in Sedadi/Klambu Kiri (42.5 km); Klambu Kanan (73 km); and Sidorejo (335 km). Assurances on the access road construction program were obtained at negotiations. 12/ Class V and IV roads are, respectively, 3.0 and 3.5 meter wide, sealed all-weather roads. - 41 - Changes in Crop Production under the Project 5.04 The project will increase agricultural production on about 59,340 ha in the Serang River Basin. The major crops grown are rice, maize, soybeans, mungbeans and sorghum. Minor crops such as groundnuts, sugar and cassava have been ex.cluded from the analysis. The main benefits will result from the provision of a reliable and timeLy supply of adequate irrigation water and the mitigation of flood damage, allowing production of two crops of irrigated rice in the project area followed by secondary (palawija) crop production on about one third of the area. 5.05 Cropped Areas and YieLds. Overall cropping intensity for rice will increase from a current (weighted) average of about 105% in the four areas to 200Z at full deveLopment. Cropping intensities for the total cropped area (rice plus palawija) will increase from a present weighted average of about 175% to 230% with the project at full development (Table 5.1). Table 5.1: CROPPING INTENSITY (Z) Present Preproject /a Future without Future with Paddy & Paddy & Paddy & Paddy & Area Paddy palawija Paddy palawija Paddy palawija Paddy palawija Sidorejo 85 266 85 266 85 266 200 230 Sedadi 145 179 145 179 145 179 200 230 Klambu Kiri 102 153 102 153 102 153 200 230 Klambu Kanan 86 166 119 206 119 206 200 230 Average /b 105 175 115 188 115 188 200 230/c /a After drainage is completed. Tb Weighted. 0c High cropping intensities of 240% have been achieved in the Jatiluhur Project over 200,000 ha (Irrigation V, Cr. 512). 5.06 Based on water availability and the existing technology available to farmers, a cropping intensity of 230% with the project is reasonable. Thnis change results in an incremental area of 83,430 ha growing rice (wet and dry season), an 236% increase over the present. The area planted with palawija crops will decline by 20,200 ha or 52% (Table 5.2). The only net increase in commandable area is in Klambu Kanan where a 15% increase occurs due to the impact of drainage activities under the Irrigation XIV Project (Ln. 1811-IND). - 42 - Table 5.2: CROP AREAS (ha) Future without Future with Crop Present project/a project Wet season Irrigated paddy 27,350 27,350 59,340 Rainfed paddy 29,930 32,230 Maize 495 495 Dry season I Irrigaced paddy 7,900 7,900 59,340 Maize 18,200 22,090 Soybean 5,165 5,165 Maize/soybean 2,880 3,280 - Dry season II Maize/soybean 5,060 5,060 6,000 Maize/mungbean 5,830 6,540 11,820 Sorghum 890 1,120 - /a After drainage works under Irrigation XIV (Ln. 1811-IND) are completed.

The expected future yield estimates are shown in Annex 2, Table 3. The projected yield estimates take into account both the impact of the Irrigaticn XIV Project (due to be completed at end-1986) and the negative impact of any continuing flood problems in the area. 5.08 Production. Paddy production in the area will rise substantially from about 0.20 million tons per year in 1984 to about 0.54 million tons per year with both the proposed project and Irrigation XIV. Incremental annual rice production at full development (1993) will be about 0.34 million tons, but secondary crop production will decline by about 12,780 tons from the current level of output. Eliminating the impact of the Irrigation XIV Project, incremental rice production due solely to the proposed project will be about 0.29 million tons per year at full development, but palawija produc- tion may decline by 35,480 tons per year (Table 5.4). These increases in agricultural production will generate about US$41 million in annual incremental agricultural benefits (Annex 2, Table 11).

In accordance with the implementation sche- dule (Annex 4), the phasing of agricultural build-up is presented in Annex 2, Tables 12 and 13. Full agricultural benefits are assumed to be achieved after one year in Sedadi and over three years (50Z in year one, and 75X in year two) in the remaining areas after each part of the irrigation system is completed. Full agricultural deveLopment of the total project area is reached in 1993, four years after the completion of the dam. VI. MARKET PROSPECTS, PRICES, FARM INCOMES AND PROJECT CHARGES Market Prospects 6.01 Central Java is only now approaching self-sufficiency in rice. Although the world price of rice has fallen sharply (para. 6.02) almost eliminating the subsidy received by farmers, production will be encouraged to guarantee the stability of Central Java's rice self-sufficiency and provide surplus rice for other regions. Thus marketing prospects for paddy should remain favorable, and in the event of lower prices, farmers are expected to increase palawija crop production. -45- Prices 6.02 Economic and financial prices for major agricultural inputs and outputs are presented in Annex 2. Table 1. Estimated farm inputs and outputs are valued in constant January 1985 prices in farm budgets and economic analyses. Economic prices for rice, maize, soybean, mungbean, sorghum and fertilizers are based on the world market price forecasts produced by the Bank's Commodities and Export Projections Division adjusted for transportation, processing and handling costs to che farmgate. Financial prices for all commodities and economic prices for inputs not traded internationally have been updated from actual farmgate orices. In the past, COI maintained low consumer food prices by subsidizing the sale of imported rice and holding domestic floor prices Low. To offset an adverse impact on producers, GOI subsidized fertilizer and pesticide prices. in recent years in order to encourage production, paddy floor prices have been raised consider- ably. In addition, recent declines in the world rice prices have contributed to almost eliminating the rice subsidy. For project analysis, financial prices of rice have been assumed to converge with economic prices. To dis- courage the excessive use of fertilizers and reduce subsidy elements, COI, in early 1983, raised the price of urea and triple superphosphate (TSP) from Rp 70/kg (unchanged since 1977) to Rp 90/kg. However, the domestic price is still below the border price and is expected to remain low in the 1990s. Farm Incomes 6.03 Three typical farm sizes (0.2 ha, 0.4 ha, 0.6 ha) have been selected for farm income analysis in Sidorejo and Klambu Kanan and three (0.1 ha, 0.4 ha and 0.6 ha) in Sedadi and Klambu Kiri. In the analysis it is assumed that the farm family, consisting of 4.6 persons, provides 1.7 man-days of labor for 22.5 days per month. In the months of peak labor requirement such as planting or harvesting, when most of the month's activity must be completed in about ten days, it is assumed that labor is hired. This amounts to about 20% of the total labor requirements at full development. It is aLso assumed that all animal labor will be hired. In addition, there are a few off-farm employment opportunities, the majority being seasonal tobacco or factory work in centers such as Semarang, Demak or Kudus. These employ predominantly women or young adults at an average wage of about Rp 600/day. These representative farm models, shown in Annex 2, Tables 15a-d and 16 a-d are summarized in Table 6.1. - 46 - Table 6.1: NET FARM INCOMES PER CAPITA /a (1985 US$) Z of Increment at Farm total Future full develop.

The remaining 102 of the farm area is farmed by sharecroppers under the 'bawon' system, whose income is usually 1/7 or 1/10 of the harvest value. 6.05 The moat recent Bank estimate of the absolute poverty leveL (in end- 1983 terms) for rural areas in Central Java is about US$103.5 per capita per - 67 - year, similar to the level for all tndonesia of about US$103.1.131 However, consumption estimates indicate chat since i980, the position of Central Java compared to the ryX5 of Indonesia has worsened. Bank estimates of the inci- dence of povercy _ reveal that rural areas in Central Java have a greater concentration of poverty (62%) than all Indonesia (43% of the national popula- tion are estimated to have incomes below the absolute poverty Line). It is expected that the majority of notentiaL beneficiaries would remain at incomes below the absolute poverty level without the project. On the smallest farms (0.1 in the Sedadi and Klambu Kiri and 0.2 ha in Sidorejo and Klambu Kanan), incomes will remain below the absolute poverty level with the project. Nevertheless. farmers wilL stii be substantially better off, and incremental incomes are espected to rise between about 47% and 145%, with a weighted average increase of 98Z over the whole project area. 6.06 Encome Distribucion. The project area inciudes: about 87,000 farm operator households; about 11,000 farm laborer househoLds which are separate from owner-operators and about 22,000 living within owner-operator households; and about 23,000 nonfarm households. An area of about 2,000 ha of drained swamp land in the Klambu Kanan area will be redistributed to landless agricul- tural labor in the project area. Comparing tenant income with owner-operator income, the income of former cenants will increase by about 20-25% in Klambu Kanan, 15-20X in Sidorejo and about 15% in Sedadi and Klambu Kiri. The income of landless laborers (only 101 in project areas) is estimated to increase by 5-10% due to increased farm employment. Project Charges 6.07 Indonesian farmers pay land taxes (IPEDA) and make contributions to village watermasters who are responsible for tertiary network operation and maintenance. Land is classified according to a number of physical criteria and IPEDA is charged at a fixed tariff which varies by land class and total land holding. The revenue is collected by village heads and turned over to the local (Kabupaten) and provincial administration for financing local devel- opment. Projected increases in land classes due to irrigation and other improvements and consequent IPEDA increases in each area are detailed in Annex 2, Table 17a. Assurances were obtained during negotiations that GOI will (a) reclassify for IPEDA purposes all land benefitting from project works, section by section within one year of completion of works, and (b) reassess and collect IPEDA taxes from all project beneficiaries in accordance with an agreed implementation schedule. At full development, IPEDA in the project area will range from about US$13/ha/year to about US$22/ha/year. In-kind contributions for water in the project area are 25 kg of paddy per crop. At full development, water contributions are expected to be about US$8/ha. 13/ These estimates are drawn from the 1980 Indonesia Household Expenditure Survey, released in 1983. The 1980 rupiah estimate is inflated by a price index for nine basic items of 56% from 1980 to end 1983 and converted to US$ at the prevailing exchange rate of.Rp 1,000 = US$1. 14/ Also from the 1980 Household Expenditure Survey. - 48 - Farmers will also contribute about 20 man-days of their labor, equivalent to about Rp 26,GOO/farmIyear. to operate and maintain the village level irriga- tion system. 6.08 Cost and Rent Recovers. Present and estimated future levels of IPEDA, water service concriDuEions and O&M labor contributions are summarized in Annex 2, Table 18a. At -ull development, incremental IPEDA and other charges wiLl more than offset incremental O&M outlays for main and secondary networks. It is oer-haps miore meaningful to observe the cost and rent recovery indices jhich estimate cost and rent recovery due to the stream of charges over the project's .ife. The cost recovery index. ranging becween about 6% and 26% (averaging i6Z), is the ratio of the present vaLue of incremental direct revenue (IPEDA and other contributions) to the presmgg value of incremental financial project costs in January i85 terms.-' The rent recovery index, ranging from about 6% to almost 23%. is che racio of the present vaiue of incremental direct revenue (IPEDA and other contributions) to the present zalue of incremental net financial project rent. These rates are in line with those in similar recent projects in 7ndonesia. The recovery rates are considered reasonable due to the low incomes of Droject bene- ficiaries (para. 6.05). O&M cost recovery ranges *rom about 86Z in Sedadi (0.6 ha farms) to about 355% in Sidorejo for 0.2 ha (Annex 2, Table 18c). Incremental streams of O&M contributions over the oroject's life and the resultant cost and rent recoverv index are shown in Annex 2, Table 18c. 6.09 O&M Funding. Support for O&M on the main irrigation system from the central government has been increasing steadily over the past few years. In addition, for Bank-assisted projects, part of the capital development budget (the DIP) has recently (in the 1983/84 budget) been directed to support O&M activity which has reduced the shortfalls in O&M budgets from 40% to 20%. Shortfalls in 0&M can have consequences on the agricultural benefits achieved over the project's life (para. 7.12). Additional funding sources for OE& have been agreed in principal with GOI by use of revenues collected from IPEDA. Assurances were obtained at negotiations that sufficient (see Annex 9, Table 4) and timely funds will be allocated to O&M, and that GOI will increase 1PEDA rates for reclassified land (para. 6.07), and furnish to the Bank by December 31, 1988 a plan to allocate the incremental IPEDA thus collected to O&M of project works following construction. 15/ Discounted at the opportunity cost of capital of 10% ovc-r the project life of 30 years. - 49 - VII. 3ENEFITS, ECONOMIC JUSTIFICATION AND RISKS General 7.01 The project complements the previous Bank,gupport in water resource development in the project area. EarLier projects concentrated on rehabilitating the existing irrigation system, mitigating flood problems through constructing main and some secondary drainage, and undertaking extensive tertiary development in the Sedadi and Klambu Kiri areas. The proposed Kedung Ombo Multipurpose Dam and irrigation Project will enhance water avaiLability through water storage in a dam, expansion of the irrigation area to the Klambu Kanan and Sidorejo areas. and substantial improvement of existing irrigation svstems in the Sedadi and KLambu Kiri areas. The project will also assist ongoing flood control activities through reservoir operation and the continuation of drainage works. Yainly secondary power (a total of 74 GWh per vear) will be generated resulting from the operation of the reservoir. Municipal and industrial water will also be supplied through the irrigation canals throughout the year. The proposed proiect is high on COI's development priorities in view of its large agricultural and flood control benefits, in an area mostly without dry season water, yet subject to flooding in the wet season. Benefits 7.02 Agricultural Benefits. Approximately 87,000 farm families will directly benefit from the project and their incomes will increase (para. 6.05) due to increased agricultural production valued at US$41 million (See Annex 2, Table 11). An additional 33,000 farm laborer households, 20,000 cf which are contained within farm operator households, will also benefit. There will also be indirect beneficiaries due to the improved access and communications in the area from the new feeder roads and access tracks to be constructed or upgraded (para. 5.03). The full costs of these roads have been charged to the project, although no road user benefits have been quantified. 7.03 Power Benefits. Power generation will be incidental to the operation of the reservoir and will be secondary to the main objective of providing irrigation. On average, 74 GWh of electrical energy will be generated per year. The main benefit from the energy generated will be the saving of cost of fuel from oil, diesel or coal stations. PLN's simulations indicate that for the proposed future network of generating stations starting from 1989 onward, the Kedung Ombo power station will initially accrue saving on fuel from oil fired steam stations (1989 to 1994), while in the latter years (1995-2020), it will save fuel from the coal fired plants (see Annex 2, Table 22b). Fuel savings range from US$2.7 million to over US$4.0 million per year (till 1994) and subsequently average US$4.3 million per year in financial 16/ Irrigation projects I, VII, IX, and XIV (Loan numbers 127-IND, 1268-IND, 1465-IND and 1811-IND) all in the Jratunseluna River Basin, Central Java. See Chapter 1. - 50 - terms. The economic benefic of this power is equated to the tariff revenue collected. From the commencement of power generation in 1989, this is about US$6.16 million per year.- 7.04 Employment. As a direct resuir of increased agricultural production, theLe will be a substantial increase in agricultural employment in the project area. Three distinct peaks in Labor demand will occur due to the increased cropping intensity. At full development, the incremental agricul- tural labor demand is about 8.7 million man-days (40.000 man-years), an increase of abouc 65%. This represents an increase of 10.3 million man-days (47,000 man-years) or 89% over the present (see Annex 2, Table i9). 7.05 Flood control benefits have been taken into account in formulating yield estimates. The Klambu Kanan and Klambu Kiri areas will predominantly benefit from flood control. Improved municipal and industrial water supply is Likely to reduce the incidence of water-borne diseases in village and muni- cipal areas. Health benefits and possible fishing and recreational benefits from the use of the Kedung Ombo Dam reservoir area have not been quantified in the analysis. Main Assumptions Used in the Economic Analysis 7.06 Financial costs have been converted to economic costs using the factors in Annex 2, Table 14. Expected price increases and taxes have been excluded from economic costs. No shadow price has been applied to the cost of animal labor due to the shortage of animals in the project area. However, the labor component of a team day (two mpn) has been shadow priced at 50% of the market wage. The consequent conversion factor for an animal team-day is thus 0.7. 7.07 Foreign Exchange. The exchange rate of US$1.00 = Rp 1,100 is considered to reflect the value to the economy of the foreign exchange used in the project. 7.08 Operation and Maintenance. Based on updated estimates of O&M costs for other multipurpose dams, O&M for the irrigation system alone is estimated at US$15/ha/year. The system is expected to operate at about 502 efficiency. Annual O&M for the dam and reservoir is estimated at US$0.5 million and US$0.13 million for the power plant (see Annex 9 for detailed costs). Equipment for O&M on the irrigation systems (US$1.72 million) and downriver works (US$0.87 million) is replaced in its fifteenth year. Wal O&M for all irrigation and dam facilities per ha is about US$29/ha/year._ 17/ After allowing 15Z transmission losses, negligible incremental distribution costs and an average tariff of Rp 98/Kwh in 1985 constant terms. 18/ Excluding O&M on the power component. 7.09 Economic Rate of Return (ERR). Based on the assumptions above and a project financial and eccenomic life of 30 years, the ERR is estimated at about 17.4% (17.6Z for a 50-vear scream) which is satisfactory. The flow of economic costs and benerics over the project life is presented in Annex 2, Table 20. The ERRs for che irrigation and power components taken individually are 16.7% (Annex 2, Table 21) and 25% (Annex 2, Table 22a) respectively. The equalizing discount rate for che power component taking only fuel saving is 14.1Z (Annex 2, Table 22b). Risks and Sensitivicy Analysis 7.10 The main risks associated with the project concern delays in land development due to delayed Land acquisition and inadequate operation and maintenance. 7.11 If, due to deLayed land acquisition for the dam, construction costs are lagged two years and benefits are lagged more than two years, the ERR falls to just under 13.4%. A future reduction in rice yields of about 12% in all areas except Sidorejo would result in a reduction of rice benefits of almost 20%. However, the project ERR will be 14.2%. If total benefits fell 50%, costs should decrease to just over 20% for the project to remain viable at 10%, the opportunity cost of capital. Similarly, an increase in costs of 50z could still maintain the project's viability at 11.8%. The project is less sensitive to cost overruns than to reductions in benefits, and the project can withstand a reasonable degree of cost overruns and reduced bene- fits. Cross-over values for a number of critical variables are summarized in Table 7.1. 7.12 Varying Levels of O&M. The standard level of O&M assumed for the project (para. 7.08) aims to produce an irrigation system efficiency of 50%. The estimated impact of different levels of O&M on project beneg'ts was investigated and summarized in Table 7.2. A cut in O&M budgets of 50% _t (very poor O&K) produ87d over time a system efficiency of 30%; poor O&M due to a cut in O&M of 30Z ' resulted in system efficiency of 40%. In these cases, it is assumed that O&M for the dam, reservoir, and the power component continues. In addition, it is assumed that the impact of the O&M changes occurs over 20 years. Due to the discounting process, the ERR is little affected by the impacts of changes in O&M expenditures. Comparing the change in O&M costs to agricultural benefits over the project life, however, shows a considerable trade-off. In the case of very poor O&M, "savings" of US$1.99 million (NPV) in O&M costs result in losses of US$30.25 million in incremental agricultural benefits over the life of the project. Similarly in the case of poor O&M, "savings" of US$1.31 million in O&M costs result in losses of US$8.58 million in agricultural benefits over the life of the project. L9/ Complete neglect of maintenance and operational staff is also reduced. 20/ Costs of maintenance reduced by 60% but operational staff is not reduced. 52 Table 7.1: SENSITIVITY ANALYSIS AT A 10Z OPPORTUNITY COST OF CAPITAL- Appraisal value /a Switching value Percentage Key factor (WS$m) (USSm) change (X) Present Value Incremental Agricultural benefits 239.5 121.0 -49.0 Rice benefits 256.3 156.0 -39.0 Paddy yield at full 4.0 tons/ha 3.2 tons/ha development /b to 5.0 tons/ha to 3.9 tons/ha -21.0 Dam and Structures: Construction costs 33.1 151.7 +358.0 Irrigation System: Construction costs 56.7 175.3 +209.0 Total Benefits 278.1 159.5 -42.7 Total Costs 159.5 278.05 +74.4 /a Discounted at 10%. lb Average over the project area.
