Erosion is a natural process that is difficult to remove or zero erosion rates. The purpose research was analysing erosion hazard and conservation planning. The method used is a survey and take soil samples for analysis in the laboratory. Parameters analysed: texture, volume weight, permeability and organic matter. Soil erosion rate is calculated with USLE. The calculation results show that erosion is very light (land units 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, and 12) and light (land units 5). The highest value is in moor land use (29.83 tons/ha /year) and the lowest is rice field land use (0.003 tons/ha/year). The level of erosion hazard is classified as very mild and mild, but the actual erosion that occurs exceeds tolerable erosion. Conservation actions is by increasing plant density, planting soil cover crops, adding organic matter, mulching, repair existing terraces.
