ABSTRACT
Patihan Irrigated Area (IA) is located in Ketileng Village, Todanan District, Blora Regency, Central Java Province. IA Patihan's water source comes from the Jembangan River, which contains sediment transportation. The content of large amounts of sediment enters the irrigation canal and hinders water distribution, so it is necessary to check the efficiency of the sludge bag. This study aims to determine the amount of sediment entered, determine the efficiency of deposition of sludge bags, and find the right draining time so that the performance of sludge bags can be optimal. The approximate amount of sediment transport was calculated using the Meyer-Peter and Muller, Einstein, Shun and Hung, and Engelund and Hansen methods. For settling efficiency and draining time can use the KP-02 cause. Based on the results of transport sediment calculations, the largest amount of sediment was obtained from the calculations of the Shun and Hung Method, with a yield of 1.91 tons/day and a settling efficiency of 83.75%. Draining time to optimize the performance of the IA Patihan irrigation canal sludge bag is necessary to drain it once every week.
Keywords: efficiency, sludge bag, optimal, dewatering, sedimentation.
