Productivity is the ability of a mining parameter to carry out production at any certain time. We can qualify that productivity are well-practiced when the production achieved or even beyond the target. PT Macmahon Mining Service has a different method which could gives a huge impact on production which is called split dump. The split dump method is a method where one loading point distributed material to various disposal points at the same time. Split dump method that performed at the Martabe Gold Mine still has disadvantage. Means the production still not achieved. It happened because the fleet configuration still does not have the guideline as a comparation. Therefore, research is needed regarding the split dump. This research use Burt and Caccetta’s split dump formula, where it can be optimized linear and nonlinear programming. Linear and non-linear programs implemented using solver adds-in on Microsoft Excel. Based on the studies that have been conducted, an ideal configuration can increase productivity and will produce a good match factor value.
