| Summary: | The increased demand for drinking water along with the population growth of Banjar Regency and Banjarbaru City, South Kalimantan province and stochastical hydrology component resulted in future uncertainty in the management pattern of Riam Kanan Reservoir Ir. P. M. Noor hydropower plant so that with the electric utility function of constant price such as the present, fulfillment of raw water demand in downstream is less than optimal. The Riam Kanan reservoir hydropower plant is used as an alternative source of raw water. Allocation of drinking water uses dry R10-R20 mainstay discharge which is worth 19.3-27.5 m3/second. The discharge correlation results from continuous forecasts with historical debit of 0.72 while the discrete markov forecast debit correlation with historical discharge is 0.62 so that continuous forecasting debits are considered more adaptive to historical debit. Optimal reservoir management using a continuous model has a correlation coefficient of 0.988 on the actual trajectory while using the markov discrete model of 0.902 so that the continuous model is chosen to be the most optimal model of reservoir designation for downstream water needs. Optimal reservoir management is calculated by optimal management based on future uncertainties, while utility price changes are calculated by the Bellman dynamic program method. For the discretization of the volume of 70, 35 and 10 Mm3 the gain obtained are 1462,25, 1207,66 and 990,13; 1463,98, 1209,80 and 996,28; 1470,10, 1238,12 and 1002,36. Correlation for discretization of 70, 35, and 10 Mm3 are 0,38, 0,44 dan 0,47, proving that the larger discretization is, the larger correlation between St trajectory dan St actual. |
