The area of ​​mine openings using open mine methods in Indonesia reached 95% from 146,545 hectares of mine openings. In Indonesia, the formation of a used mine hole becomes a former mine lake anticipated as an option of post-mining (mine closure). In fact, currently a mine used hole has been formed filled with water which most of them are not planned. Many mine used holes are distinguished with settlements less than 500 m and without security. Provision of data for the existence of these mine holes is considered important, especially in the form of maps, so that it can be used as a reference either by the community and for stakeholders in determining the best security strategies. The results of mapping used mine holes can be used as initial data for local government and the central government in determining policies regarding related issues. By presenting the data in the form of an integrated area in one map. Community service begins with data retrieval of satellite image and satellite image administration map, radiometric correction, analysis and classification of land use, and ground check field.
Maps as dataative data, and research data that can be used to increase security from risky areas.
The lack of information about the existence and the location of this mine-used hole makes the security level of this area to the surrounding community become low.
