Abstract

Logung Reservoir in Kudus Regency is one of the reservoirs with priority for flood management. The threat of sedimentation in the reservoir is extremely high. To prevent sedimentation in the reservoir, it is necessary to prepare an efficient sediment control method that is affordable, easy, and yields optimal results. This research will compare the economic efficiency of two sediment control methods in the reservoir: the construction of Check Dams (CD) upstream and sediment dredging in the reservoir using heavy equipment. The smallest Future Value Cost (FVc) value for 50 years between the CD construction method and Reservoir Dredging is an indication of a more efficient control method. FVc CD analysis is based on construction value, Operation, and maintenance every year, and Rehabilitation assumption every 3 years, and FVc Reservoir dredging is the operational cost of dredging once every 5 years and Rehabilitation assumption every 4 years, with the same volume of sediment. The analysis results based on a 5% internal rate show that the FVc for Check Dams is Rp. 8,584.72 billion, and the FVc for reservoir dredging, including crop losses, is Rp. 55,858.1 billion. Thus, sediment control using the construction and operation of check dams is more efficient.
