Abstract
The Ciwidey sub-watershed is part of the Upper Citarum watershed, where the watershed is one of the 15 priority watersheds in Indonesia. Where the Upper Citarum watershed suffered very heavy damage in terms of water quality, sedimentation, and erosion, so it required serious handling. The Ciwidey sub-watershed is located in most of Bandung Regency and a small part of West Bandung Regency. The Ciwidey sub-watershed is a series of the upstream Citarum watershed, precisely in the southern part of the Citarum watershed. The aims of this study are 1) Analysis of the magnitude of erosion per HRU in the Ciwidey sub-watershed using the Soil and Water Assessment Tools (SWAT) model 2). Determining the accuracy of the data from the calculation of erosion prediction for the Ciwidey Sub-watershed using Soil Water Assessment Tools (SWAT) 3). Determine the right conservation technique at the point where erosion occurs in the Ciwidey Sub-watershed. This study uses secondary data, the research method used in this study is secondary data analysis using SWAT, and the data analysis method used is quantitative and spatial analysis. The results of this study indicate that 1). The overall rate of erosion in the Ciwidey sub-watershed is 2179.36 tons/ha/year. The erosion value goes through the stages of calculating rainfall, land use, and soil type. 2). The level of accuracy of the data calculated through SWAT shows an accurate number, namely 0.56 where the number is included in the acceptable category, with a minimum data accuracy value or R2 of 0.5. 3). The results of the calculation of the erosion value are used to determine the appropriate soil conservation techniques, namely vegetative soil conservation techniques by planting soil strengthening plants and increasing infiltration, including avocado, jackfruit, durian trees which are applied to dry agricultural land.
