Abstract
Tirtomarto reservoir or their people call it the Delingan reservoir because of its location in the village of Delingan, Karanganyar District, Karanganyar Regency, Central Java Province in Indonesia, it has an important role in meeting irrigation needs for agricultural land covering area of ​​1380 ha every year, but over time the Delingan reservoir is now visible. experienced a decrease in its water capacity and resulting in a decrease in water supply for agricultural land. This is due to the large value of land erosion that occurs. This study aims to calculate the value of land erosion that occurs in the catchment area of ​​the Delingan reservoir which can later be handled so that sedimentation in the reservoir can be overcome and the water supply is maintained. Prediction of soil erosion in this study using the USLE (Universal Soil Loss Equation) and MUSLE (Modified Universal Soil Loss Equation) methods. The results of this study obtained the value of the erodibility factor of rain (R) from 2015-2019, the soil erodibility factor (K) of 0.04, the length and slope factor (LS) of 1.991134206, the factor of land cover plants and the factor of conservation measures. (CP) of 0.035456901. In the USLE method, the erosion value is 7605.891488 tons/year. Then the maximum flood discharge value (QP), surface runoff (QQ), and surface runoff (R) can be obtained so that the erosion value using the MUSLE method is 862.88 tons/year.
