Analysis of Fleet Management System Network Infrastructure in Open Mining System

This study was conducted to assess the conditions and weaknesses of the network infrastructure used by the Fleet Management System at PT Saptaindra Sejati which is a coal mining contractor company in Indonesia. The results of this study are to find weaknesses in network infrastructure, especially in the Fleet Management System that runs on network coverage. Analysis of signal strength in the PT Saptaindra Sejati mining area found that there were several areas that received bad signals. This condition is one that hinders operations at PT Saptaindra Sejati which affects the Fleet Management System, resulting in a freeze system display. The optimization that can be done after getting the research results is to provide a topology design and the addition of supporting devices to achieve stable network coverage. Based on the research conducted, PT Saptaindra Sejati believes that the performance of network coverage after optimization will be better than before optimization.
