HASIL PLAGIASI ANALISIS EROSI DAN TINGKAT BAHAYA EROSI PADA BERBAGAI TIPE TUTUPAN LAHAN YANG BERBEDA DI SUB DAS BANYUIRANG DAS MALUKA

Abstract

This study aims to analyze erosion and the level of erosion hazard in the Banyuirang watershed in the Maluka watershed. The method used in this study is the USLE (Universal Soil Loss Equation) method. The results showed that the value obtained from the erosion rate calculation was the highest in the reed with a value of 399.44 tons / ha / year and the lowest value in the plantation with a value of 1.64 tons / ha / year. This shows that the absence of vegetation affects the soil which will be damaged and affects the rate of erosion, especially on steep slopes. The level of erosion hazard varies from very light class (0-SR), mild class I (IR), moderate class 2 (II-S), heavy class 3 (III-B) and very heavy class 4 (IV-SB), class which is very heavy in the reed and bush land. While the level of erosion hazard is very mild located in reed, bush, plantations and secondary forests. The value of erosion hazard level is obtained from the value of erosion rate with erosion hazard class and soil solum depth.
