Abstract
The research was conducted on andesite mining atPT.DewataBumi Nusantara, Sidomulyo Village, Pengasih District, KulonProgo Regency, Special Region Of Yogyakarta.Andesite mining with quarry method causing the environmental damage such as abiotic, biotic, culture, and neglected ex-mining land in the research location. The purpose of this researchis to determine the physical condition of the environment in andesite mining atPT.DewataBumi Nusantara and to provide the effortsreclamation for andesite ex-mining land atPT.Dewata Bumi Nusantara based on the physical condition of the environment. The method used isobservations and measurements in the field.Sampling techniqueusing nonprobability samplingwithpurposivesampling, and scoring method used for data analysis. The parameters used are extensive land clearing against mining permits, topsoil taken to be managed, slope of excavation wall, high of excavation wall, andthe risk of disruption due to mining,which refers tothe Special Region Of Yogyakarta GovernorDecisionNumber 63/2003 AboutRaw Criterias Of Environmental Damages For BussinessAnd Excavation Activities For Group C Extractive Material In Special Region Of Yogyakarta. By the results of measurements and analysis on the research location, showed that environmental damage levelis categorized into the level of damage with a score of 2 = moderate, and the calculation result of topsoil 28.215 LCM. Effort reclamation which suggested is using pot cropping system with 3 meters distance between holes.The things that need to be consideredis arrangement pattern on mine excavation such as slope of excavation wallmust be ≤33,3%, high of excavation wall must be ≤3 metersandtop soil pile must be ≤1 meter. Keywords :effort, reclamation, mining, and andesite.
