Abstract

PT Bintang Sinar Perkasa plans to mine Pit C in Block B, Morowali Regency, Central Sulawesi. The pit covers approximately 20.98 hectares and contains an estimated 502,366 tonnes of ore. This study determines excavation and hauling equipment requirements and estimates ore getting costs. A quantitative approach combined field observations and company data, including equipment cycle times, haul-road geometry, production targets, equipment specifications, rental rates, fuel, lubricants, tyres, and operator wages. Theoretical productivity and equipment requirements were calculated for a 13-month production schedule. The results indicate a requirement for one Sany SY215C excavator for digging and one Sany SY365Hpro excavator for loading throughout the schedule. Hauling requires 14 Sany SYZ324C-8W(R) dump trucks during months 1–12 and eight units in month 13. Estimated equipment rental costs are IDR 15,141,085,714, while operating costs are IDR 40,001,619,838, resulting in total ore getting costs of IDR 55,142,705,552. These theoretical estimates provide a planning basis and require comparison with actual operating performance during mining.
