Abstract

Perusahaan X merupakan salah satu perusahaan pertambangan yang mengelola kekayaan alam berupa batu andesit. Perusahaan melakukan penambangan permukaan dengan metode quarry yang berlokasi di Desa Kalirejo, Kecamatan Kokap, Kabupaten Kulon Progo, Daerah Istimewa Yogyakarta. Tujuan penelitian ini adalah menganalisis potensi bahaya pada kegiatan penambangan serta melakukan upaya pengendaliannya dengan menggunakan metode pengendalian risiko dari Keputusan Direktur Jenderal Mineral dan Batubara Kementerian Energi dan Sumber Daya Mineral No. 185.K37.04.DJB. 2019. Hasil penilaian risiko kejadian berbahaya berdasarkan penilaian AS/NZS 4360:2004 adalah: Pada tahap penggalian terdapat 4 kejadian berbahaya risiko tinggi dan 2 kejadian berbahaya risiko sedang. Pada tahap loading terdapat 3 kejadian berbahaya risiko tinggi dan 2 kejadian berbahaya risiko sedang. Sedangkan untuk tahap pengangkutan, terdapat 3 kejadian berbahaya risiko tinggi dan 1 kejadian berbahaya risiko sedang.

Abstract

Indonesia is an archipelagic country that has abundant mineral wealth, both metal minerals and other minerals. Metal minerals, including gold, tend to have a higher economic value. Based on data from the Ministry of Energy and Mineral Resources, the world's gold reserves in 2020 were 50,300 tons of Au. Indonesia is among the 5 largest in the world with 5% of the total gold reserves, which is 2,600 tons of Au. Therefore, it is necessary to develop technology and science in the mining industry, especially gold and silver, to improve the optimization of the process and increase the added value of the mining products themselves. One of the gold extraction processes can be done hydrometallurgically with the cyanidation method using a intensive leach test. The results of this experiment show that factors such as cyanide usage and ultra fine particle size will greatly affect the recovery of gold and silver metals.
