N2 - Erosion that exceeds the normal threshold can cause damage to the environment. The reduction of the physical properties of soil is a result of erosion. The USLE method is an empirical model that can predict the amount of erosion. The purpose of this study was to determine the level of erosion hazard that occurs in the Tanralili sub-watershed. The benefit of this study is to find out areas that are experiencing severe erosion so that a recovery plan can be made for eroded soils to prevent even more significant decay Erosion calculated using the USLE (Universal Soil Loss Equation) model. There are several variables used in the calculation, which are the rainfall erosivity factor, the soil erodibility factor, the topographic factor, and the cropping management factor in looking at vegetation cover in the field using a survey method. The analysis used in this study is descriptive and spatial. Very high erosion occurs in almost all of the Tanraliili sub-watershed, about > 480 tons/ha/year, which happened in slopes 15-45%. Massive erosion occurs in the west with a total amount of 180-480 tons/ha/year. The total erosion that occurred in 2018 was 701542.9 tons/ha/year.
