An important role Bili - Bili Reservoirs to meet the needs of irrigation, raw water and electricity demand the need for structured existence of optimal operation pattern. The pattern of operations that include elevation calculated surface water reservoirs, discharge outflow, and inflow. Optimization is done by searching for the value of the raw water and electricity shortage most of at least a year, and the cropping pattern following irrigation of existing. Terms limits that are used include the minimum and maximum operating limits for the volume of the spooler, widespread inundation, water surface elevation of reservoirs, and also discharge flowing through the turbine intakes and irrigation outlets. The simulation is performed based on the inflow discharge during the 20 years from 1998 until the year 2017. Optimization of the Trade-off is done based on the extremely dry year 2002. The results of a trade-off in that year compared with the year inflow discharge dry, normal, and wet (probability 80%, 50%, and 20%). The simulation shows that the minimum surface elevation reservoirs thus occur at the beginning and the end of the year, so Bili Bili Reservoirs – ready to accept and accommodate excess water from DAS Jeneberang in the rainy season. This happens because the needs are great at the beginning and the end of the year. The results of the optimization operation of reservoirs with the aim to minimize raw water shortages would result in surface elevation of the water reservoir which is lower than the optimization with the function to minimize the shortage of energy.
