and hold water. For this reason, it is necessary to carry out an analysis related to erosion in the Lematang Enim sub-watershed based on the influencing factors, namely rain erosivity (R), soil erodibility (K), slope length and slope (LS) and land use (CP). Based on the results of the analysis of the values of the factors that influence the highest erosion, in 2010 the rain erosivity value (R) was 1.57 MJ.mm / year, with soil erodibility (K value) of 0.28. the slope is> 40% and the land use value (CP) is 0.43. In 2019, the erosivity of rain (R) was 1.02 MJ.mm/year, with soil erodibility (K value) of 0.28. the slope is> 40% and the land use value (CP) is 0.43. Based on data analysis that has been calculated using the RUSLE equation method with the help of the ArcGIS 10.5 program in 2010 and 2019. the results of erosion analysis using the Revised Universal Soil Loss Equation (RUSLE) equation, the average erosion that occurred in 2010 was 1, 66 tonnes / ha / year and erosion on slopes > 40% that occurred in 2010 of 9.56 tonnes / ha / year, which is located in areas with agricultural land use mixed dry land mixed with shrubs, has a yellowish red podosolic alluvial soil type & podzolic, with a slope of > 40%. The average erosion that occurs in 2019 is 1.08 tonnes / ha / year and erosion that occurs on slopes > 40% in 2019, which is 6.21 tonnes / ha / year, is located in areas with average erosion -The average that occurred in 2019 was 1.08 tonnes / ha / year mixed with bushes, had yellowish red and podosolic alluvial soil types, with a slope of> 40%.
