Prediksi Erosi Menggunakan Metode Universal Soil Loss Equetion (USLE) dengan Aplikasi Sistem Informasi Geografis (SIG) di Sub Das Babura

Abstract

The Deli Watershed has been potentially critical in recent years, due to limited monitoring and prevention of erosion. This research aims to determine the magnitude of soil erosion and the level of erosion hazard in the Babura Watershed using the Universal Soil Loss Equation (USLE) method. The results of this study showed the highest erosion value was 215.29 tons/ha/yr, and the lowest was 0.0807 tons/ha/yr. The highest tolerable erosion value gets a value of 47.3 tons/ha/yr and the lowest gets a value of 34.2 tons/ha/yr. For the highest erosion hazard level, the value is 6.22. Has an erosion risk class III with moderate criteria and the lowest value is 0.019 has an erosion risk class I with very mild criteria.
