Abstract:
The type of land cover affects the level of erosion hazard in an area. The purpose of this study was to analyze the amount of erosion hazard and determine the level of erosion hazard (TBE) on the reed vegetation on various slopes in the Bati-bati sub-watershed of the Maluka watershed, South Kalimantan. Sampling of data using purposive sampling technique. Samples were taken as many as 6 land units based on vegetation, soil type, reed land cover and slope class, which were obtained from the map overlay of land units. Each sample point was taken soil samples using a sample ring to be tested in the laboratory. Then, the data were analyzed using Universal Soil Loss Equation (USLE) and Erosion Hazard Analysis (TBE). The highest number of erosion values occurred in reed Land Unit (UL) 39 with a slope of 15-25% with an erosion value of 130.96 tons/ha/year, while the lowest erosion value was found in UL 34 with a slope of 0-8 and erosion of 9.64 tons/ha/year. The erosion hazard level of the land unit under study shows the percentage of light grade (IR) occurring at UL7, UL 34, UL 50 and UL 59 with a flat slope (0-8), while the medium grade (II-S) occurs at UL. 37 with gentle slopes (8-15) and UL 39 with steep slopes (25-40).
