Daftar Isi:
- Research was conducted upstream catchment area of Komering. The method used in this study is to survey the level of semi-detailed, where observation and sampling conducted on the basis of soil maps with a scale of 1: 50,000 to 1: 25,000. The pattern of systematic sampling is done based on the existing base maps at four levels of steepness of the slope as well as three forms of land use. The purpose of this study was to identify and predict the potential magnitude of erosion on different slopes of land use with different slope in the upper watersheds (DAS) Komering. The condition of the river area and the mainland have shown that DAS Komering has disorder or deterioration of ecosystems and environmental quality due to illegal logging to area ponds, plantations that do not pay attention to the principles of environmental sustainability and the turbidity of water in estuaries Komering. The lowest value erosion in the upstream watershed sfud5r area is in forest Komering (HT1) that is equal to 5.79 tons/ha/year, while the highest erosion values are in the area of mixed farms (KC3) that is equal to 348.65 tons/ha/yr. Recommended control measures is necessary that the rate of soil erosion and land rehabilitation in the catchment area so that environmental degradation is widespread and severe.
