Conclusion

From the excursion site visit to fews of dams in west java, we can conclude that

1. Operational Standard of Ir H Djuanda Dams have to coordinate with two another dams in Saguling and Cirata, related the flow of the water.

2. The use of Ir H Djuanda dams is as electricity power plant with the installed capacity 187.5 MW, with the use of irrigation for 242.000 Ha, the supply needed for household, industrial sector, and capital city water demond, supply for brackish water aquaculture along north coast of west java for 20.000 Ha. While the Jatigede Dam has a function to irigate 90.000 Ha of ricefield and service the clean water with the capacity of 3.500 electricity in a second and produce the hydropower with the installed capacity around 110 MW.

3. The operational standard and safety is monitored by instruments tools that already installed, covering piezometer,surface monument, accelerometer and seismometer.

a. Highlight about Curug dam

Curug dam is a main dam that located in kosambi satu, purwakarta. Curug dam devide the water debit into three main area. The first one West tarum for service of Jakarta and bekasi area, north Tarum for north coast and east tarum. The function of curug dam is as a watershed for PDAM and has a controlled for citarum river flood. The background of the curug dam mega conctruction is to handle some problems as the impact of the jatilhur dam constructed. The jatiluhur dam also has three main function. First to fulfill the needed of irrigation system, clean water demond, and for the hydropowerplant. The requirenment of the hydro powerplant has a regulation that the elevation water of energy is 80 meters so at the downstream, the surface of the water is contructed as low as possible so the demond for irrigation,supply of clean water can be obtainable by using the pumping system. For covering these problem, curug dam is constructed with the hydraulic polder pumping system at low elevation. This impacts are to complicate the shaft to rotate so that the water that comes out to be fewer and lower

b. Technical dataGenerally, curug dam build into 5 main sector
