Abstract

Based on the Minister of Energy and Mineral Resources Indonesia Decree No. 1827.K / 30 / MEM / 2018 concerning Guidelines for the Implementation of Good Mining Practices, every mine company is required to implement OHS requirements in the work environment through measurement and control of the work environment including physical, chemical, biological, ergonomic, and psychological factors. Noise is one of the physical risks in mining due to sound intensity due to the operation of work equipment. PT XYZ in this study is one of the largest copper mines in Indonesia which processes 120,000 tons / day of rock and operates 111 units of the 793C Catterpillar Haul Truck. Grinding or grinding functions to grind the material to a size small enough so that mineral particles containing copper and gold can be easily separated by the flotation process. The grinding process consists of 2 SAG Mill and 4 Ball Mill which have noise intensity above 90 dB. Noise control programs for work sites that have exposures above the threshold are in place to prevent work related-illness. The steps taken in the noise conservation program are carried out in a number of steps, namely noise surveys, audiometric tests, efforts to eliminate noise sources, engineering, administrative, education and training, provision of ear protection equipment, recording and reporting, program evaluation, and program audits.
