Abstract
Target produksi overburden dan batubara yang telah direncanakan oleh PT. Bukit Asam (Persero) Tbk Tanjung Enim pada bulan September 2013 pada Pit 3 Banko Barat sebesar 720.000 bcm/bulan dan batubara sebesar 300.000 ton/bulan. Permasalahan yang terjadi adalah bagaimana produktivitas alat mekanis untuk pengupasan tanah penutup dan penambangan batubara dan berapakah biaya dari pengupasan tanah penutup per bcm dan biaya dari penambangan batubara per ton. Peralatan mekanis yang digunakan untuk pengupasan lapisan tanah penutup adalah 3 unit bulldozer D 9 R, 6 unit Backhoe 385 C, dan 30 unit DT HD 773 E. Sedangkan peralatan mekanis untuk penambangan batubara adalah 1 unit bulldozer, 2 unit Backhoe 345 D, 11 unit DT Scania P 420, 'Dari hasil kajian ini produksi overburden dan batubara pada bulan September 2013 sebesar 794.080 bcm bcm/bulan dan 196.157 ton/bulan. Total biaya pengupasan tanah penutup (overburden) sebesar Rp. 18.527,00/bcm dan total biaya penambangan batubara sebesar Rp 96.000,00/ton
