ANALYSIS OF THE LEVEL OF EROSION HAZARD IN THE FRAMEWORK OF THE GREEN REVOLUTION IN WATERSHED MALUKA PROVINCE SOUTH KALIMANTAN

Abstract

This study aims to analyze the rate of erosion and identify the level of erosion hazard in the Maluka watershed. The method used in the study is the USLE (Universal Soil Loss Equation) method. The results showed that the values obtained from the calculation of erosion rates were the highest existed in open land valued 708.77 tons/ha/year and the lowest value was in young secondary forests of 30.33 tons/ha/year. This shows that the absence of vegetation has an impact on the soil so that it is damaged and gives effect to the erosion rate, especially on steep slopes. The level of erosion hazard varies from medium class (II S and III S), weight (III B) and very heavy (IV-SB), very heavy classes are on open land. The value of the erosion hazard level is obtained from the value of the erosion rate with the class into the soil solution.
