Abstract


This study aims to determine the erosion rate of land use, determine the allowable erosion, determine the erosion hazard index and conservation action efforts in Pasui Sub Watershed Upper Saddang Watershed Enrekang Regency, the research was conducted from March to May 2023. Analysis of the results of this study using Wischmeier (1978) or USLE method to test Erosion Prediction, Allowable Erosion, and determine the value of Erosion Hazard Index in Pasui Sub Watershed Upper Saddang Watershed Enrekang Regency. Prediction of the level of erosion rate (A) generated in the study in land use with two types of soil, the highest erosion rate (A) value is dominated by residential land use on Inceptisol soil with a value of 1457.12 tons/ha/year while the lowest erosion rate (A) value is obtained in primary dryland forest land use on Ultisol soil with a value of 3.58 tons/ha/year. Allowable Erosion in the Upper Pasui Sub Watershed of the Saddang Watershed, from the results of the study, is found in the land use of Ultisol soil settlements and Inceptisol soil dry land farming, where the Ultisol soil settlement land has an effective soil depth value of 288.00 mm while the Inceptisol soil primary dry farming is 266.00 mm, this indicates that the soil layer is shallow. The results of the IBE research have shown that residential land use, dryland agricultural land use mixed with shrubs and shrubs that experience erosion with a very high rate.
