Abstract

Cahaya Ganda Gindi is a nickel company engaged in nickel mining. PT. Cahaya Ganda Gindi's nickel ore mining is currently in the operational stage with topsoil stripping and overburden excavation activities, laterite nickel mining, and laterite nickel transportation. There are community activities around the mining site so the environmental conditions need to be maintained and maintained so that the activities of residents in the area are not disturbed. Topsoil stripping and overburden excavation activities, as well as laterite nickel mining activities have an impact on decreasing the quality of surface water and seawater quality. This decrease in water quality is due to increased surface water flow/erosion from the mine front. The implementation of this seawater quality test is carried out by taking seawater samples at several points and then conducting laboratory tests to determine the quality of the seawater in the hope that the community will know the quality of the seawater around them so that mitigation steps can be determined if pollution exceeds the specified quality standards

Abstract

Pada kegiatan pemboran diperlukan kajian perencanaan dengan maksud menghindari masalah yang dapat menyebabkan target produksi tidak tercapai. Masalah yang ditemukan dalam penelitian ini yaitu bagaimana cara untuk mengetahui efisiensi kerja, produktivitas dan besaran biaya pemboran pada PT. Putra Konawe Utama. Tujuan penelitian ini adalah untuk mengetahui efisiensi kerja alat bor, produktivitas alat bor dan besaran biaya yang dikeluarkan pada kegiatan pemboran eksplorasi. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif yang mengutamakan kajian pustaka berdasarkan hasil observasi secara langsung dilapangan dan kemudian data-data yang diperoleh diolah dengan menggunakan rumus-rumus perhitungan sehingga dapat diketahui hasil efisiensi kerja, produktivitas dan besaran biaya pemboran pada alat bor yang digunakan. Hasil penelitian ini menunjukan presentase dari efisiensi kerja alat bor sebesar 55,46%, produktivitas alat bor sebesar 2,76 meter/jam dan besaran biaya pemboran yang digunakan meliputi: biaya penggunaan bahan bakar sebesar Rp1.277/jam, biaya oli gear sae 10 sebesar Rp1.305/jam, biaya oli mesin sae 40 sebesar Rp150 /jam biaya penggemuk atau grease sebesar Rp1.570/jam dan biaya operator sebesar Rp25.641/jam.

Abstract

PT. Diamond Alfa Propertindo is a company that produces gravel stones ranging from 0.5 cm to 3 cm in size, located in Southeast Sulawesi, with a land area of 4,905 hectares. PT. Diamond Alfa Propertindo has a production target of 25,000 tons per month, with an average production of 22,000 tons per month. The company employs open-pit mining using the Quarry method, with mining locations divided into blocks A1, A2, A3, currently in the mining phase. The extraction of limestone involves drilling and blasting activities to meet production targets, posing high risks of workplace accidents, occupational diseases, fires, explosions, landslides, and environmental pollution. These risks arise from workers' non-compliance with safety regulations, unsafe working conditions, inadequate facilities and infrastructure, or poor management, as well as unsafe environmental conditions. The implementation of Occupational Health and Safety (K3) is the responsibility of every mining employee, from the highest leadership level to field executives or operators. This is conveyed through a combination of methods such as lectures, discussions, and demonstrations. The community service activities aim to ensure that the limestone mining activities of PT. Diamond Alfa Propertindo in Buton Tengah are carried out with an understanding of the importance of occupational health and safety in creating a comfortable and safe working environment for mining workers.
