PT Berau Coal as one of the companies engaged in the coal industry business is one of the companies with the largest production capacity in Indonesia. In 2022 PT Berau Coal's total coal production target is 33 million tons. One of the sites with the largest total coal production of PT Berau Coal is the Lati Mine Operation site with a total coal production target in 2022 of 8.5 million tons. Some things that can be an obstacle to the mining process carried out include the ratio of blending materials in the disposal area, based on the results of reserving in 2022 the total soft material that needs to be handled is 33 million BCM with hard blasting material for blending only 80 million BCM, then the existing blending ratio is only 2.44 or a shortage of 1.11 from plan 3.55. Then another problem faced is related to distance hauling overburden which is getting farther and farther towards the west area. Based on the 2022 actual distance review, the existing distance figure is 3,039 compositely (for a total fleet of 35), while the plan for 4 fleets that will run and enter the western disposal area is 4,760 KM from the 2022 plan of 3,380 KM. Based on the results of the analysis carried out, it was found that the most suitable project is the Channel Dump project. The project is a new improvement in the disposal area by applying technology for the surveillance process, dumping in the highwall area using channels and the use of steel hoppers as a sliding pad (channel) foundation. With the implementation of the Channel Dump project and after analysis related to impact and benefits on K3 and operational aspects, results were obtained related to increasing the blending ratio from 2.44 to 3.4, reducing distance compositely by 25 meters (for a total fleet running of 35 units), increasing sequence accuracy from 88.9% to 91.2%, and increasing compliance disposal from 70% to 76%. Based on the results of the financial analysis study, the potential of the Channel Dump project to produce an NPV value of < 0 is 0%, with an NPV value of Rp. 2,429,003,770.83, PI 1.37, PBP 1.17 and IRR 38.15%.
