Abstract

PT Banjarsari Pribumi merencanakan target produksi satu juta ton batubara dari pit middle pada tahun 2023, sehingga diperlukan suatu perencanaan penambangan yang dapat menunjang pencapaian produksi. Penelitian bertujuan untuk merencanakan penambangan yang mencakup desain pit dan disposal, sequence penambangan bulanan dengan penanganan matrial OPD ABC timur dan analisis keperluan alat gali muat dan angkut. Perancangan pit penambangan, disposal dan sequence bulanan dibuat menggunakan bantuan software minescape 5.7 dengan cara dilakukan penentuan blok penambangan dengan uji coba secara berulang serta batasan nilai stripping ratio 6,2 dan target produksi bulanan yang ditetapkan. Berdasarkan hasil rancangan pit diperoleh perhitungan volume 1.014.675 ton batubara dan 5.821.600 BCM overburden dengan stripping ratio 5,74. Rancangan pit dibuat dengan memperhitungkan pengambilan kembali material OPD ABC timur yang berada di pit middle dan rancangan sekuen penambangan dijadwalkan bulanan yang dapat memenuhi pencapaian produksi batubara sebanyak satu juta ton. Arah penambangan dimulai dari side wall timur melanjutkan penambangan sebelumnya menuju side wall barat dengan luas bukaan 39,18 Ha. Rancangan penimbunan disposal dibuat secara inpit dump pada area IPD ABC seluas 44,30 Ha yang dapat menampung overburden sebesar 7,99 juta BCM.

Abstract

The sustainability of the mining industry is highly dependent on the availability of natural reserves of minerals. The conversion of land that was originally intended as a forest or garden into a mining area has caused people around the mine to change professions. However, professions or businesses that arise as a result of mining activities can only last as long as the mine is still operating. Then a big question mark arises regarding the sustainability of the community's economy after mining. With limited resources, MSMEs (micro, small and medium enterprises) based on the creative economy are one of the businesses that can be applied to empower post-mining communities. This study aims to determine the ranking of alternative creative economy MSMEs that can be developed in communities around the mine in Lahat Regency. The method used is the analytical hierarchy process (AHP). This study was conducted by determining the criteria for creative economy MSME businesses and alternatives and then continued with collecting primary data for paired comparisons using a questionnaire. Furthermore, data processing was carried out to determine alternative rankings and consistency ratio testing. The results of the study showed that the highest ranking of alternative creative economy MSMEs was the snack food culinary subsector, followed by the woven craft subsector, the textile craft subsector, and the traditional beverage culinary subsector in sequence.
