Abstract

This research aimed to evaluate the existing condition of the Jatigede reservoir regarding the inflow and outflow of water use and whether the water usage has been optimal. Based on the observation, floods often occur upstream of the Jatigede reservoir, so the evaluation result will become input for the optimization of water management in the Jatigede reservoir, which, according to the plan, will analyze the water conservation in the reservoir upstream. The methodology consists of an analysis of inflow using a tank model, an analysis of irrigation and hydropower demands, an analysis of the spill-out through the spillway, and an analysis of the inflow in the weir that is under Jatigede reservoir. The data indicates that the full supply level (FSL) is attained following two weekly periods of three weeks each. Based on this condition, it is estimated that water use is not optimal or completely safe. In addition, the water conservation in the upstream region of the Jatigede reservoir has not been analyzed.


Keywords: Jatigede reservoir, inflow, irrigation, hydropower.
