Abstract
This study aims to determine the amount of soil erosion and the danger index of erosion in several lands uses in Dadakitan Village, Baolan Sub-District, Toli-Toli Regency. In this study, slope class maps and land use maps were overlaid, in order to obtain six land uses include the use of paddy fields, coconut plantation, cocoa plantation, cloves plantation, and forests. Erosion prediction was carried out for all land uses. The survey was then carried out on six land uses to observe the slope and the dominant vegetation. Soil samples were taken deliberately for each land use; three samples for each sample of intact soil and disturbed soil. Erosion prediction analysis was using the USLE (Universal Soil Loss Equation). The results showed that the erosion hazard index occurred in Dadakitan Village was classified as low, high, and very high. Low erosion occurred in paddy fields, coconut plantation, and cocoa plantation. In contrast, high levels of erosion occurred on clove plantation, and very high erosion level occurred on forest lands. The dominant factors affecting the occurrence of erosion in this area were soil erodibility, topography, plant management, and conservation measures.
