Abstract
Abstract PT Cipta Bersama Sukses (PT CBS) calculates the volume of excavated materials using the mine progress survey method or truck count method. The common obstacle in the calculation is the discrepant results between survey production volume and truck count production volume. In November 2023, PT CBS set the production target of 291,790 BCM in overburden stripping production. It prompted this study to identify the causes of the discrepancy between the cut-and-fill calculation volume and the truck count volume, as well as the causes of the difference in target volume and actual production volume. We expect to provide references to the company in improving the performance quality the following month. This quantitative study gathered data from survey activities in the field and analyzed the data using Surpac 6.5.1 software. The total volume of overburden removal results in November 2023 using the cut-and-fill method was 331,446.883 BCM, and the truck count volume was 313,237.500 BCM, indicating a 5.494% difference with a standard deviation of 6.37%. It prompted the evaluation of data collection and calculation review. This research has achieved the overburden production target of 114% cut and fill volume and 107% truck count volume.
