Differencial Global Positioning System (DGPS) is a enhancement of the available publicly Global Positioning System (GPS) to increase its accuracy. GPS function to determine an object location in the earth’s surface by using orbiting satellites. Terminal Operating System (TOS) is the core application used by container terminal for both for planning, monitor and execute the containers movement from truck to yard, yard to truck, truck to vessel and vessel to truck using heavy lifting equipment (called Container Handling Equipment – CHE). In most cases, DGPS implementation within TOS for automatic container tracking will contributed significantly to reduce operating cost, therefore, this research analyze the benefit of this implementation. The author use balanced scorecard approach as performance metrics to define, measure and analyze the benefits of implementing the integration between DGPS and TOS by comparing the results before and after the implementation. The benefits of the implementation can be explained by reducing Truck Round Time(TRT) by 38.17% compared year 2016 to that of year 2013. Box Container per Hour (BCH) increase 16.67%, whereas operating cost decrease 3.3% compared year to that of year 2013.
