Recovery Engineering of Ex-Illegal Sand and Stone Mining on the Slopes of Mount Merapi

Abstract

This study aims to study the environmental damage caused by illegal/illegal mining of sand and stones on the slopes of Mount Merapi and the impact of the land restoration plan and its management efforts. The location of this research is in Sleman Regency, DIY, especially in Karangkendal Hamlet. Balong Hamlet, Umbulharjo Village, Cangkringan District. This area has attractive ecotourism or ecotourism potential which is supported by the majority of land use for agricultural land, aspects of nature conservation, aspects of socio-cultural economic empowerment of local communities, as well as aspects of learning and education. However, this location is also one of the locations for the deposition of sandstone and cold lava when Mount Merapi erupted. The material is a construction material so that under normal conditions, there is a process of illegal mining of sand and stone at that location by the community around the location. Problems arise due to mining activities without prior technical planning resulting in environmental damage at the location, both on the contours of the mined land into steep cliffs that are prone to landslides and disturbances to the vegetation and fauna. CV. Rubi Khan Daiman as a third party who got a job from the Sleman Regency Government to carry out land recovery mitigation activities, then collaborated with researchers to conduct the study. Based on the research results, the planned land restoration activities will not only have positive impacts but also negative impacts on the surrounding environment.
