Abstract

The research was conducted in Banaran Hamlet, Keningar Village, Dukun Subdistrict, Magelang District, Central Java, which is a mining area for sand and rock, previously the area was a private forest. Mining system used in the form of open pit mining and traditional mining methods. The purpose of this research is to determine the level of land and the technical design of mine reclamation mining areas at the study site.
