ANALISIS COST AND BENEFIT RENCANA PEMBETONAN JALAN ANGKUT BATUBARA DI LOKASI BANKO TENGAH BLOK B PT BUKIT ASAM TBK

---

PT Bukit Asam Tbk (PTBA) in Tanjung Enim, South Sumatra, a mining company uses the surface mining method with dump trucks to transport coal. The condition of the haul road greatly affects the productivity of the equipment, especially during rain which causes slippery and standby time. To improve performance, PTBA maintains the road and creates All Weather Road (AWR) in several segments. In the Banko Tengah Block B IUP development area, the road segment from Pit 3 Timur, Pit E, and Pit SJS to Dump hopper 5 (DH 5) along 6 km is often disrupted due to bumpy road conditions. PTBA plans to concrete the road along 1.7 km to reduce slippery time and increase operational efficiency, while conducting a cost and benefit analysis to ensure its economic feasibility. The purpose of this study is to analyze the actual geometric conditions of the haul road from Simpang Bangjo to Dump hopper 5 (DH 5) and its coal productivity, evaluate the concreting plan of the haul road from Simpang Banjo Banko to DH 5, and conduct a benefit and cost ratio analysis arising from the concreting plan. The results of the discussion show that the existing geometry of the haul road from Simpang Bangjo Banko to Dump Hopper 5 has a length of 1.74 km, a width of 15.2–36.68 m, a cross slope of 30.4–73.36 cm, a bend radius of 10.29 m, superelevation of 16.8° and 7.2°, and a road grade of
