Indonesia is one of the countries that has the largest coal reserves in the world, which is 39,891 billion tons. In 2019, 42% of coal reserves in Indonesia were in East Kalimantan, so many mining companies operated in the area. When regional autonomy the existence of coal companies increased significantly. This led to increased coal production and East Kalimantan GRDP dominated by the mining sector. In addition to having a positive impact, mining activities also have a negative impact. The negative impact of coal mining activities in East Kalimantan is the emergence of a used mine or void hole on the last mining activity. Based on the special monitoring to the former location of the Komnas Yam with the Komnas HAM with the coalis of the mine hole, there were around 25 people who sank in the former mine hole listed in 2016. Therefore, the need for special studies to overcome this. Remote sensing technology can be used for mining environmental monitoring activities. This research adverts remote sensing technology to see the impact of coal mining in the city of Samarinda East Kalimantan Province in the form of voids. Void distribution can be determined from the results of NDVI analysis, NDWI and MNDWI, KLHK land cover maps, and Wiupindonesia maps. Void criteria are areas that have negative NDVI values, ndwidan mndwi positive, are in the Wivya area and mining areas based on land cover from KLHK. Based on these criteria, it can be said that Void is widely found in the southern and western regions of Samarinda City (Palaran Subdistrict, Remarks and River Kunjang).
Final report
As the data for the initial study in the management of environmental impacts of coal mining on the island of Kalimantan, especially South Kalimantan Province and East Kalimantan (for South Kalimantan Province being carried out by studies separately)
