Lack of attention and conservation efforts as well as the increasing encroachment of forest land is a problem in land use of Krueng Simpo Sub Watershed. The number of forest encroachment resulting in degraded forest lands and switching functions in the upstream, so that it can cause erosion and sendimentation in the downstream. The purpose of this research is to evaluate the level of erosion in Krueng Simpo Sub Watershed on various types of land use with conservation techniques are applied to do with the income of farmers. The descriptive exploratory method was applied ini this research and erosion prediction using USLE method. Questionnaire was used to obtain input and output data from each type of land use. The results of this research showed that the greatest erosion occurred on the moor of 90,9 tonnes / ha / year followed by a mixture garden of 50,0 tonnes / ha / year and the smallest in the forest area of 0,7 tonnes / ha /  year. Income derived on conservation techniques in the form of a teras traditional and teras gulud acquired for 22,925,000 ha / year, and 2,865,625 ha / year.

Keywords: Watershed area of Krueng Simpo, various land use, level of  erosion, soil
