Abstract

Pada daerah dataran tinggi sering terjadi erosi yang disebabkan oleh tergerusnya tanah akibat energi kenetik hujandan pengaruh lainnya seperti jenis kepekaan tanah, penggunaan lahan, serta panjang dan kemiringan lereng. Tujuan dari penelitian ini adalah untuk menghitung indek erosivitas serta mengetahui besarnya erosi pada Sub DAS Lematang Hulu, yang merupakan wilayah perbukitan di Sumatera Selatan. Dalam penelitian ini digunakan Model RUSLE (Revised Universal soil Loss Equation) yang merupakan model yang digunakan untuk memperkirakan besarnya erosi yang disebabkan oleh besarnya energi kinetik yang bekerja pada daerah tersebut. Hasil penelitian menunjukkan nilai erosi maksimum pada sub DAS Lematang Hulu adalah 5904,146 Ton/Ha/Tahun, nilai erosi minimum 4,168 Ton/Ha/Tahun sedangkan nilai erosi rata-rata 2904,157 Ton/Ha/Tahun. Secara umum pada wilayah penelitian terjadi erosi rata-rata sebesar 4,168 Ton/Ha/Tahun.
