PT Adaro Indonesia (AI) is one of the largest thermal coal producers in Indonesia with production of around 40-50 million tons per year. AI’ mine are open pit mine that located in the Balangan and Tabalong Regencies of South Kalimantan Provinces names Paringin, Tutupan and Wara. AI’s main business processes are managing mining production operations and selling to customers. To transport coal from production sites to sales points, AI travels by land and river. For the transportation by land, AI employes a contractor namely PT Sapta Indra Sejati (SIS), while the transportation by river is handled by PT Adaro Logistics (AL). Land coal transportation is carried out from the Stockpile/ ROM (run-of-mine) to the Barito river port in Kelanis dedicated coal Terminal using a coal trailer with a capacity of 140-ton trough dedicated hauling road along 86 kilometres. One coal hauling cycle takes approximately five hours. It is including loading time at the stockpile, hauling time, weighing time on the bridge, dumping time at Kelanis and back to Stockpile. In the period of January – April 2022, the average hauling cycle time is 5 hours 14 minutes which means exceeding the agreed time at the beginning of the year which was 5 hours. This has an impact on the non-achievement of sales target in the period that ultimately has an impact on not achieving the company’s revenue target. The focus on this research is to analyse the root cause of the non-achievement of cycle time targets on the dedicated hauling road and will identify the solutions to improve the conditions. The methods used are quantitative and qualitative to obtain data and information from various company stakeholders. The root cause of the problem is identified based on the data then validated based on the results of interviews and literature studies. The problem concluded from this study are transportation time and weighing time. The hauling time is affected by the average travel speed of the trailer, while the weighing time is affected by the change shift of trailer operator. Therefore, the root causes are road conditions (including pothole), operator trailer change shift and community intersections. Community Intersection is the intersection of Adaro Dedicated Hauling Road to the Community Road. Since Adaro holds the IUPK for the Continuation of Contract/Agreement Operations from the Government, it is by law that Adaro should give priority to the community to pass the road. Therefore, the recommended solution to increase the average travel speed of the trailers based on the root cause analysis is to increase road maintenance, while to reduce weighing time is to reschedule the number trailer operator shifts.
