Pendugaan Tingkat Bahaya Erosi (TBE) dengan Sistem Informasi Geografis: Studi Kasus di DAS Bedadung Kecamatan Panti
Abstract
The Bedadung River Basin is a watershed that is mostly located in Jember Regency
and a small part of its area is located in Bondowoso Regency with a total area of
102,434.1 hectares. The Bedadung watershed in Panti District has quite high
erosion potential. Erosion is the process of moving soil on the surface of the land
as a result of water flow. Erosion rate calculations need to be carried out to predict
soil loss and determine the level of erosion danger. Erosion rate predictions are
calculated using the USLE (Universal Soil Loss Equation) method which is
integrated with GIS (Geographic Information System). GIS is used to calculate soil
loss according to USLE parameters and depict it in the form of a map. The research
results showed that the erosion hazard level of the Bedadung watershed, Panti
District, was divided into five categories. The very light erosion hazard level has
an area of 298.11 hectares, the light category has an area of 3,182.51 hectares, the
medium category has an area of 2,213 hectares, the heavy category has an area of
1,571.16 hectares, and the very heavy category has an area of 192.37 hectares. The
very light erosion hazard level in the use of paddy fields The light erosion hazard
level on flat forest land, moorlands, plantations and settlements. The moderate
erosion hazard level in the use of moorland, plantations and forests. The severe
levels erosion hazard level in forest and bush land use. The very heavy erosion
hazard level in forest land use which is located on steep slopes.
