Abstract

The volume of sedimentation in the Bengawan Solo river is 592,936.05 m3 per year. Several check dams have been built to overcome the sedimentation problem. However, this check dam building has experienced a decrease in performance due to sedimentation. Therefore, the research in this thesis aims to determine the priority of maintenance and repair of sediment control buildings (check dams). Determining priorities due to lack of budget for buildings processed by the government. Use guidelines for classifying check dam damage and building maintenance. Determining maintenance priorities based on the condition of the building using the analytical hierarchical process method. The location of the case study is a check dam building on the Bengawan Solo River and the results of the analysis show that the one with maintenance and repair priorities is the ploso check dam with severe damage (42.5%) and the maintenance carried out is rehabilitative (performance <60%).
