Erosion Hazard Classification Analysis in Kantung the Watershed, Bangka District

Abstract

Watersheds in the Bangka Belitung Islands Province are increasingly experiencing environmental damage from year to year. Location of the Kantung Watershed in Parit padang Sungailiat Bangka Village. The causes of damage to this watershed are mining activities, land use changes that were previously forested as residences and agricultural land that is not managed properly so that the impact is reduced forest as a natural protector, erodible soil or erosion. The method of analysis carried out in this study is the USLE (Universal Soil Loss Equation) approach. Based on the analysis that has been carried out by the USLE method, the total erosion size of the Kantung watershed is 521,684 tons / ha / year 3,140,190,871 tons / year / year with Class V (Very Heavy) erosion hazard classification. Based on the results of the erosion hazard classification obtained is class V (Very Heavy), with large erodibility, the slope of the dominant slope is very steep, changes in land cover especially for mining activities, residences and agricultural land without management, the recommendations for reducing erosion are mechanical and vegetative soil conservation methods
