      Abstract
      Mount Sindoro slope is a tobacco plantation area. Based on variations in slope, there is erosion potential on most of the slopes. This study aimed to determine the way of structuring tobacco plantations in the eastern region of Mount Sindoro due to intensive land use. This research was conducted in Gunungsari Village, Bansari District, Temanggung Regency, from April to July 2018. This research was conducted using a survey method and continued with the determination of the level of soil erosion potential on area A (more than 20% slope), area B (15- 20 % slope) and area C (less than 15% slope) using USLE method. Landscape planning was carried out based on the application of land conservation methods with the main purpose of reducing the level of erosion potential using agronomic and mechanical methods. The results show that the actual erosion potential of area A, B and C is 42.67 tons/ha/year, 44.81 tons/ha/year and 31.80 tons/ha/year, respectively, and is categorized as moderate to severe erosion level. The application of agronomic methods in the form of intercropping systems of tobacco and peanuts could reduce the erosion potential from 42.67 to 32.43 tons/ha/year (area A); from 44.81 to 33.61 tons/ha/year (area B) and from 31.80 to 23.85 tons/ha/year (area C). Meanwhile, the application of the ridge terraces and bench terraces, consecutively, reduced erosion potential from 42.67 to 6.40 and 1.71 tons/ha/year (area A); from 44.81 to 6.72 and 1.79 tons/ha/year (area B); and from 31.80 to 4.77 and 1.27 tons/ha/year (area C). Thus, it can be concluded that bench terraces is more effective in reducing erosion potential than ridge terraces.
