| dc.description.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. | en_US |
