Abstract: Water supply at DI Molek (Irrigation area of Molek, Kepanjen Regency-Indonesia) is deficit on the low and dry discharge seasonal year. To solve this problem, there is needed to reallocate water supply for getting the maximum benefit. This study intends to optimize the irrigation water supply at DI Molek. Water supply for irrigation in this area is not enough during dry season. It is needed a pattern of water supply allocation to get the maximum net benefit for allocating water supply in this season. The Dynamic Programming is used to carry out this problem. Result shows that the benefit of water supply allocation at DI Molek would be increase 6.37% for low discharge seasonal year and 10.86% for dry discharge seasonal year.
