摘要：

The Indonesian archipelago has abundant mineral resources, and it causes many mining activities. Mineral resource is natural based resource which cannot be renewable. An abandon mining pit makes a hole in land surface and it increase the erosion severity level on the rainy season. This erosion would brought sediment to the sea, and it causes damage the ecosystem of the coastal. Erosion modeling in Jelateng watershed performed temporally using remote sensing image data, which consist of LANDSAT-5 (1995), and LANDSAT-8 (2015), and supported by field data as well. The parameters for modeling of erosion through rasterization process as input from erosion USLE models to IDRISI software. The results shown that in 1995, the majority of the area has a low level of erosion. The low erosion rate is less than 183.67 tons/hectare/year and high erosion rate is 408.34 up to 633 tons/hectare/year. Compare with in 2015, erosion models shown that erosion is most prevalent on the upstream area of Jelateng watershed, with low erosion rate is less than 432.2 tons/hectare/year and high erosion rate is 615.64 up to 1448.31 tons/hectare/year.
