Abstract

The plan for overburden stripping at PT Bumi Sekundang Enim Energy's Pit AB was 332,829.17 BCM/month, but the company was unable to achieve this target. This study aims to evaluate the performance of overburden stripping, identify obstacles that affect overburden stripping, and calculate the costs of overburden stripping before and after improvements are made to overcome these obstacles. This study uses a descriptive-analytical quantitative approach with a case study at PT Bumi Sekundang Enim Energy. The actual productivity of the transport equipment obtained is 20.5 BCM/hour, lower than the specified target of 22.37 BCM/hour. The failure to achieve this overburden stripping was due to obstacles that reduced effective working time and mechanical equipment efficiency. Improvements were made to delay time and idle time, successfully reducing total downtime by 40.64%. As a result, mechanical equipment efficiency increased to 77.82%. After the improvements were made, the productivity of the transport equipment increased to 25.67 BCM/hour and the overburden stripping target was achieved with a percentage of 114.76%. The operational costs of overburden stripping consist of excavation and transportation costs by mechanical equipment. The costs taken into account include fuel, lubricants and filters, tire and undercarriage replacement, ground engaging tools replacement, and operator wages. The operational cost of stripping overburden before the improvement was Rp 20,473/BCM, but after the improvement, the cost decreased by 20.14% to Rp 16,350/bcm.

Abstract

The mining sector is a strategic sector that impacts the environment and local communities. PT Bukit Asam (Persero) Tbk. implements a Community Development and Empowerment (PPM) program to strengthen harmonious relations between the company and surrounding communities, as well as to support sustainable development. Community Service (PKM) activities are carried out through direct visits to partner villages, including Desa Impian, a village established and developed for calliandra cultivation as part of reclamation efforts and as a training center for the surrounding community and former PETI mine employees located in Tanjung Karangan Village, Tanjung Agung Subdistrict, Muara Enim Regency, South Sumatra Province, as well as the Bukit Asam Small Industry Center (SIBA). Located in Tanjung Enim, Lawang Kidul Subdistrict, Muara Enim Regency. The SIBA program serves as the operational hub and primary focus of PT Bukit Asam Tbk’s (PTBA) SME empowerment initiatives.  The Community Engagement Program (PKM) activities, carried out in collaboration with PTBA, aim to identify local potential, assess community needs, conduct outreach, and provide assistance in various sectors, including economic, social, environmental, and educational. The implementation of this PKM program has yielded significant results, including improved harmonious relations with the surrounding community, the creation of economic self-reliance, and sustainable improvements in the quality of life.
