ABSTRACT: Mining can cause changes in the shape of landmasses and lead to erosion. Erosion results from the interaction of climate, soil, topography, vegetation and human activity on natural resources. The purpose of this study is to analyze the level of soil erosion and provide direction for land conservation priorities. The analytical method using the Universal Soil Loss Equation (USLE) method. USLE has five parameters is rainfall erosivity factor, Soil erodibility factor, terrain factors: the slope length and slope steepness, land cover and management factor, Conservation practices factor. The soil erosion rate is composed of five classes; very low, low, moderate, heavy and very heavy. The final results of this study based on the danger level of soil erosion with analysis overlay the map could indicate that erosion very heavy consists of 30%, heavy 5%, moderate 25%, low 10% and very low 30%. Priority for land conservation is based on the land conservation index table which is from very heavy erosion to very low erosion. To minimize current erosion rates by adopting a vegetative method.
