Abstract

There are coal mines in East Kalimantan Province, one of which is in North Penajam Paser Regency. The existence of a coal mine, resulting in changes in land use around it. The purpose of this study is to identify land use changes in 2009 - 2019 and analyze environmental damage based on the level of erosion. The data required is in the form of land use in 2009 and 2019 which is obtained based on interpretation using Landsat imagery and verification of existing land uses. The images used are Landsat 7 and 8 imagery. To identify land use changes, the data processing method used is pixel based image classification with the supervised maximum likelihood classification technique. The analysis method used is an overlay. The result of this research is a decrease in forest area due to coal mining activities in Penajam Paser Utara Regency. There was an increase in the area of built land, open land and mining areas. The wider the mining area, the higher the level of erosion. Therefore, the environmental damage that occurs will be even greater, such as silting rivers and waterways
