Land degradation occurs due to soil erosion, which may cause flooding and drought. Therefore, this study aimed to analyze the factors causing erosion and determine how to control it. Materials and Methods: The survey method of observing and measuring soil samples, vegetation and soil conservation techniques applied in each land unit was used. Rainfall data, soil characteristics, slopes, crop management and soil conservation techniques were collected and analyzed using USLE. Results: The results showed that the erosion in the Siak watershed is relatively high (339 tons/ha/year). Furthermore, the plant management and soil conservation techniques did not follow the required principles and the erosion control was determined by improving crop management and soil conservation techniques in an integrated manner at each unit of land. This step was expected to reduce erosion in the Siak watershed. Conclusion: The erosion control in open land areas resulting from clearing need to get top priority. Guidance in the form of counseling and specifically regarding the soil conservation method needs to be carried out earlier and in stages to all landowners.]]>Uy, N. and R.
