Background. Development of Jatiluhur Irrigation Project started in year 1925 by construction of Walahar weir including the irrigation system called North Tarum Canal (NTC) with 77.41 km length of canals and irrigated 85,945 ha paddy field. In year 1965 it was followed by construction Curug weir located 8 km just upstream of Walahar weir, completed with irrigation system. The irrigation system from Curug weir divided into 2 (two) parts, for the left side called West Tarum Canal (WTC) with 68.67 km of canal length to irrigate 56,628 ha of paddy field and for the right side called East Tarum Canal (ETC) with 67.37 km of canal length to irrigate 90,230 ha paddy field. The total irrigation area of Jatiluhur is 232,803 ha. This area spread over 4 (four) districts in West Java Province; they are Purwakarta District, Karawang District, Subang District and Indramayu District. Beside for irrigation purpose, the Jatiluhur System also functions as water supply for Domestic, Municipal and Industrial (DMI) for the people and company along or around the canal and for Jakarta drinking water. Citarum river is the longest river in West Java Province with 270 km of length with abundant water. At the upstream portion of river, the Government constructed 3 (three) dams. The first dam located at the upstream of Curug weir is called Juanda Dam as a multi-purpose dam for hydro-electric plant (PLTA) and regulator water for Jatiluhur Irrigation System. The capacity of Juanda dam is 3 billion m³. More upstream there are Cirata dam and Saguling dam having functions as a hydro-electric plant (PLTA). Water supply for Jatiluhur Irrigation system is controlled and regulated by Juanda dam, firstly water use for electric power station, and then water flowing to downstream through Citarum river. At the Curug weir, the water pumped by hydraulic pump to the left irrigation canal WTC with capacity of 85 m³/sec, and by electric pump to the right irrigation canal ETC with capacity of 84 m³/sec. The excessive water flows to the downstream of Citarum River and at the Walahar weir is diverted to irrigation canal of NTC with capacity of 102 m³/sec. In line with the rapid development in various sector, the water requirement for domestic, municipal and industrial sectors also increase. The existence of Jatiluhur Irrigation Canals becomes more important. But on the behind, after operated more than 45 years, the capacity of canals has been reduced continuously. The main factor reducing the conveyance capacity of the canals is the sediment flowing with irrigation water and settled in the canals. For example, the capacity of ETC is now only 62.5 m³/sec, this is 1 only 75% of designed capacity of 84 m³/sec. Due to reducing capacity, the conflict of using water becomes more serious. In order to solve the problem of water supply at the Jatiluhur Irrigation System, the Government of Republic Indonesia, through Department of Public Works, Balai Besar Wilayah Sungai Citarum (BBWSC) plans to improve the irrigation system by implementing Water Resources and Irrigation Sector Management Program (WISMP-2) Stage 2, especially in West Java Province named Jatiluhur Irrigation Management Improvement (JIMI) Loan 4711-IND. According to Loan Agreement, the improvement work should be executed in accordance with environmental requirement. 2. Location. The Environmental Assessment was carried out for the 3 (three) Sub-Systems of Jatiluhur irrigation system, such as Barugbug Cs, Pawelutan Cs, and Salamdarma Kiri Cs, which administratively locate at Subang district, West Java Province. SS Pawelutan Cs and SS Salamdarma Kiri locate at the Binong Sub-District and SS Barugbug Cs locate at Jatisari Sub-District. Location of sub-systems can be seen in Figure 1 attached. 3. Scope of Works for 3 Sub-Systems in the 1st year Program Scope of work for Improvement of Jatiluhur Irrigation System are divided into several packages. For the first stage planned in year 2011-2012, the rehab works for the 3 Sub- Systems in East Tarum Canal (ETC) will be implemented with the details as below: 1. SS. Pawelutan Cs for area of 3,592 ha, consists of 30,876 m canal long with the excavation work of 183,578 m3, improvement of embankment for 136,718 m3, canal lining for 8.803 km with 9,988 m³ of stone masonry and rehabilitation of 81 nos of structures. 2. SS. Barugbug Cs for area of 2,901 ha, with the irrigation canal of 15,791 m long, the excavation work of 18,484 m3 and improvement of embankment for 32,487 m3, canal lining for 6.087 km with 12,176 m³ of stone masonry and rehabilitation of 27 nos of structures. 3. SS. Salamdarma Kiri Cs for area of 2,922 ha, with the irrigation canal of 16,437 m long, the excavation work of 39,366 m3 and improvement of embankment for 29,782 m3, canal lining for 9.418 km with 21,733 m³ of stone masonry and rehabilitation of 22 nos of structures. For more clear, the scope and quantity of the work can be seen in Table 1 attached. 4. Construction Equipment. The Construction Period is planned for 18 months. For the execution of rehabilitation works as above will be used several kinds of the equipment consisting of bulldozer, excavator, vibrator roller, watertank truck, dump truck, concrete mixer and concrete vibrator. The required number of such equipment can be seen in Table 2 attached. 2 5. Environmental Assessment. For the environmental assessment for Improvement of Jatiluhur Irrigation system, various

NOORDUYN BUJANGGA MANIK'S JOURNEYS THROUGH JAVA: TOPOGRAPHICAL DATA FROM AN OLD SUNDANESE SOURCE One of the precious remnants of Old Sundanese literature is the story of Bujangga Manik as it is told in octosyllabic lines — the metrical form of Old Sundanese narrative poetry — in a palm-leaf MS kept in the Bodleian Library in Oxford since 1627 or 1629 (MS Jav. b. 3 (R), cf. Noorduyn 1968:460, Ricklefs/Voorhoeve 1977:181). The hero of the story is a Hindu-Sundanese hermit, who, though a prince (tohaari) at the court of Pakuan (which was located near present-day Bogor in western Java), preferred to live the life of a man of religion. As a hermit he made two journeys from Pakuan to central and eastern Java and back, the second including a visit to Bali, and after his return lived in various places in the Sundanese area until the end of his life. A considerable part of the text is devoted to a detailed description of the first and the last stretch of the first journey, i.e. from Pakuan to Brëbës and from Kalapa (now: Jakarta) to Pakuan (about 125 lines out of the total of 1641 lines of the incomplete MS), and to the whole of the second journey (about 550 lines).

  • Assessment of the Effects of Climate and Land Cover Changes on River Discharge and Sediment Yield, and an Adaptive Spatial Planning in the Jakarta Region
    ASSESSMENT OF THE EFFECTS OF CLIMATE AND LAND COVER CHANGES ON RIVER DISCHARGE AND SEDIMENT YIELD, AND AN ADAPTIVE SPATIAL PLANNING IN THE JAKARTA REGION Poerbandono1, Miga M. Julian2, and Philip J. Ward3 ABSTRACT In Jakarta, climate change has been detected through rising air temperatures, increased intensity of rainfall in the wet season, and sea level rise. The coupling of such changes with local anthropogenic driven modifications in the environmental setting could contribute to an increased probability of flooding, due to increases in both extreme river discharge and sedimentation (as a result of erosion in the watersheds above Jakarta and as indicated by sediment yield in the downstream area). In order to respond to the observed and projected changes in river discharge and sediment yield, and their secondary impacts, adaptation strategies are required. A possible adaptation strategy is through policy making in the field of spatial planning. For example, in Indonesia, presidential regulation number 54 year 2008 (Peraturan Presiden Nomor 54 Tahun 2008 - Perpres 54/2008) was issued as a reference for the implementation of water and soil conservation. This paper assesses the impact of climate and land cover change on river discharge and sediment yield, as well as the effects of Perpres 54/2008 on that river discharge and sediment yield. The spatial water balance model STREAM (Spatial Tools for River Basins and Environmental and Analysis of Management Option) was used for the runoff computations, whilst the SDAS model (Spatial Decision Assistance of Watershed Sedimentation) was used to simulate erosion, Sediment Delivery Ratio, and sediment yield. The computation period is from January 1901 to December 2005, at the scale of the following watersheds: Ciujung, Cisadane, Ciliwung, and Citarum.
