Abstract

The danger level of erosion at each land closure and Slopes has different results. It is important to know the handling of erosion hazards later. The purpose of this study is to calculate the amount of erosion due to changes in land closures and to know the level of erosion hazard (TBE) of rubber plantations on various slopes in Sub Das Bati – Bati Das Maluka. The research method is purposive random sampling. Sample points taken based on soil type, slopes class, vegetation, and land cover are adjusted to the land units of the land unit map (overlay). Soil sampling using ring samples and soil drills will then be tested. Land cover and marbles are closely related to erosion values. The highest erosion value is in Land Unit (LU) 38 with an erosion value of 73.64 tons/ha/yr, while the lowest value is at LU 7 with an erosion value of 6.34 tons/ha/yr. The degree of erosion hazard is related to the soil solum. Erosion hazard level in all land units and land cover indicates grade II-S (medium) is present at LU 38 while light (I-SR) is on, LU 37, LU 50, and LU 59, and very light (0-SR) is on LU 7 and LU 34.
