There have, of course, been other examples of new reservoirs creating valuable fisheries and aquaculture opportunities, but the work reported here - a highly fruitful cooperation between the Indonesian State Electric Company (PLN), the Institute of Ecology (IOE) of Padjadjaran University, Bandung, the West Java Provincial Fisheries Agency and its Technical Management Unit for Saguling and Cirata (UPTD) and the International Center for Living Aquatic Resources Management, with the farsighted support of the World Bank - is a rare, if not unique example of an effort to develop reservoir fish production technology for a clearly identified and resourceful target group (those displaced by the reservoir development) whose interests, resources and aptitudes were considered from the earliest inception of the reservoir construction planning. Moreover, the need for adequate institutional and technical support, training and extension as the aquaculture and fisheries technologies evolved and sustained support to farmers and fishermen thereafter, were also recognized and emphasized by all concerned. Any new reservoir is like a big 'experiment' with respect to its aquaculture and capture fisheries potential. No one can predict with certainty how productive the ecosystem will be, which species will predominate, which (if any) should be introduced, how the entry to capture fisheries and aquaculture should be managed, which regulations to enact, whether the original fishermen and fish farmers will persevere or will leave their operations for others to continue, the possible risks of fish kills, diseases, conflicts between different users, and myriad other questions. Indeed any new aquatic ecosystem, its exploiters and beneficiaries comprise a highly dynamic and evolving situation. What looks promising early in the life of the reservoir may not be sustainable. This underlines the need for sustained institutional support and constant monitoring of the ecology of new reservoirs and their catchments. The objectives of this project were to identify appropriate aquaculture and fisheries methods for resettled families; to conduct research for the development of aquaculture technology that would create employment; to provide technology transfer, training and extension advice to farmers and scientists; and to complete a comprehensive fisheries and aquaculture development plan for two reservoirs. All these objectives were achieved. As the development plan went to press and the Cirata Reservoir was filling, 1,083 displaced families from the Saguling area were involved in fish production, 2,081 persons had been trained, and the reservoir was supplying over 20% of the freshwater fish entering the Bandung district, an area with over three million people. Equally rapid development is anticipated in the Cirata Reservoir. Moreover, these developments have had a flow-on effect in that fish seed supply (especially from rice-fish culture systems), feed supply and fish handling operations have expanded and benefited more people over a wide area. In addition to the comprehensive development plan, there were additional benefits in the form of advances in research methodology and scientific and extension publications that will have much wider impact than in the Saguling-Cirata target area alone or indeed in Indonesia. A list of these publications is appended (Appendix 1). These together with this Technical Report can help the planning and execution of tropical reservoir fisheries and aquaculture development elsewhere. PLN-IOE-UPTD-ICLARM teamwork made these results possible. All concerned hope that the start made through this project towards aquaculture and fisheries development in the Saguling and Cirata Reservoirs will result in a sustainable improvement in the livelihood of those who live around them and will point the way to similar developments elsewhere.

Water is a necessity of life for creatures in this world. No water, no life. The existence of water, other than according to the hydrological cycle, at a particular place, at a particular time, and in particular quality as well as quantity is greatly influenced by a variety of natural phenomena and also by human behavior. Properly managed water and its resources will provide sustainable benefits for life. However, on the other hand, water can also lead to disasters, when it is not managed wisely. Therefore, it is highly necessary to conduct comprehensive and integrated water resources management efforts, or widely known as “Integrated Water Resources Management”. In the same way, river management efforts as part of the river basin integrated water resources management, include efforts on river utilization, development, protection, conservation and control, in an integrated river basin with cross-jurisdiction, cross-regional and cross- sectoral approach. This book outlines how water resources development and management in several river basins are carried out from time to time according to the existing situations and conditions, Besides, it covers various challenges and obstacles faced by the policy makers and the implementers in the field, The existing sets of laws and regulations and the various uses and benefits are also discused.

  • The Use of Water Quality Index System in the Assessment of Water Pollution Control
    Evaluation of the suitability of Citarum river water for different uses Mohamad Ali Fulazzaky1, 2, ∗; Mochammad Basuki Hadimuljono2 1Department of Water Resources and Environmental Engineering, Faculty of Civil and Environmental Engineering, Universiti Tun Hussein Onn Malaysia 86400 Parit Raja, Batu Pahat, Johor, Malaysia 2Ministry of Public Works Jalan Pattimura No. 20, Kebayoran Baru, Jakarta 12110, Indonesia Abstract The Citarum river water is the most important water sources in Indonesia. The river that supports a population of 28 million people, delivers 20% of Indonesia's gross domestic product, and provides 80% of surface water to carry through the West Tarum Canal to the Jakarta’s water supply authority, is one of the most polluted rivers in the world. Water quality degradation of this river increases from the year to year due to the increasing pollutant loads when released particularly from Bandung region of the upstream areas into river without treatment. This will be facing the chronic problems of water pollution for supporting the suitability of water for different uses. This study used the Water Quality Evaluation System to asses the suitability of water in term of the Water Quality Aptitude (WQA) for five different uses and its aquatic ecosystem. The assessment of ten selected stations was found that the WQA ranges from the suitable quality for agriculture and livestock watering uses to unsuitable for biological potential function, drinking water production, and leisure activities and sports upstream the Saguling reservoir, generally. The role of Citarum river water in providing the demands of multipurpose uses particularly for Jakarta’s water supply will still be present in question for the years to come.

Enhanced availability of nitrogen is a cause of eutrophication of rivers, lakes, and estuaries worldwide. In this study, Cita- rum River Basin, West Java, Indonesia was selected as a target area, supplying 80% of domestic water to Jakarta Metrop- olis. Meteorological and hydrological data from 1996 to 2009, and spatial data such as topography, land use, soil proper- ties were collected for model simulation. Conceptual nitrogen balance model, which has three nitrogen pools, was devel- oped and combined with rainfall runoff model. Proposed model was applied to the Citarum River Basin and simulated river discharge and nitrogen load in 1 km×1 km resolution to check the model applicability.

H. Djuanda has to meet the water supply requirements as a multipurpose dam, therefore optimize operation of these three reservoirs is necessary for maximizes dependable water to meet several needs with existing limitation. Reservoirs operated by means of rule curve that relates storage and time. Several curves can be applied at the same time depending on the position of the next periods of the release that are taken. The dynamic programming method as a famous and classic method to optimize a reservoir system was chosen to applied. This method is possible to decide under uncertainty with in the most optimal “path” of reservoir level. The rule curves produced had been optimized with respect to power production in the system. At the same time monthly target storage was derived with respect to flood protection and water supply for all purposes. Different purposes and various operators on managing reservoir operation induce conflict of interests. Optimization method cannot always be applied considering the complexity of constraints that must be adopted. To overcome of these limitations the policies are brought about in the form of coordination forum, and optimization is conducted by simulation and sometimes without optimizing the hydropower production.

Citarum River flows from the mountainous area in Bandung, through the three cascade dams: Saguling, Cirata, and Jatiluhur, before finally flows to Java Sea. Surface water from Upper Citarum River Basin is a plateau area surrounded by mountain range which forms a basin which flows into Saguling Dam. This geographical condition causes the rainfall runoff on the mountain range tend to flow into the basin area, resulting in high discharge surface flow during wet season. The high discharge unfortunately is not accommodated with adequate channel capacity, which in this case is the Citarum River of Upstream Citarum River Basin. Consequently, during the rainy season, flood disaster often occurs around the Citarum River which flows through Bandung Regency. Heavy flood disaster in particular occurred in Dayeuh Kolot Subdistrict which brought great damages, due to the area is located adjacent to the Bandung City, the capital city where many important activities occur.

Postgraduate School of Bogor Agricultural University Abstract Jatiluhur Reservoir is the multipurpose reservoir functioning as water resources for irrigation, hydroelectric power plant, home and industry usages for the area of DKI Jakarta (capital city of Indonesia with the status of most densly populated city in the nation) and its surrounding regencies. Its existence bears other benefits to many communities such as inland fishing, tourism and water sport recreation. Last but not least important purpose, the reservoir flood has a significant role for flood control management in the area of Karawang District and its adjacent areas. Despite the many social welfares the reservoir can produce, the quality and quantity of water resources from Citarum River to the Jatiluhur reservoir bear some problems that affect some challenges in the water management. This research attempts to identify the real critical pulse of the problems by analyzing its business process in the water resources management along with their risk and impact that may affect the vitality of the business outcomes. The analysis approach for this study is using the standard of green business continuity management (GBCM) where all the of environmentally polluted/harming items are considered.
