Abstract :
The low level of sedimentation volume that enters a watershed is one of the success factors in managing watersheds. Sedimentation measurements can be carried out directly or through an erosion prediction approach. The purpose of this study is to predict sedimentation using the USLE (Universal Soil Loss Equation) erosion approach and also use sensitivity analysis. With the USLE (Universal Soil Loss Equation) method, the sediment volume value is 530,868 m3 with a service life of 65 years. In the positive sensitivity analysis method by adding and subtracting the percentage of sediment volume by 50%, 30%, 20%, 10% and 5%. So the addition of sediment volume by 50% obtained a sediment volume of 796,302 m3 with a service life of 43 years. Meanwhile, in reducing the sediment volume by 50%, the sediment volume is 265,434 m3 with a service life of 130 years.
