Abstract
The implementation of transshipment inside the terminal is normal and has been running at Tanjung Perak Harbor. However, for the domestic container terminal there are several obstacles including: in Tanjung Perak Port there is clustering per terminal seen from the Destination of the Ship, and Transshipment only runs at one terminal so that the Shipping Agent if it has advanced cargo must first exit the terminal and enter the Depo outside terminal. After the open stack at the port, for advanced loading vessels will be re-entered to the destination terminal of the carrier. Therefore, it is necessary to evaluate the Transshipment Time Performance at which point is experiencing bottlenecks so that it can be anticipated and minimized. This study proposes to analyze the time in the transshipment business process. The analysis process begins by describing SOPs into the YAWL model. Then mining is done to find out the companys performance. After that, the results of mining are optimized using Linear programming. linear programming method was chosen because the method is very suitable for determining the results of optimization in the same variable, the variable is time. The result of time in this transshipment business process is increase from 7 days become 3,5 days. It shown that this method is successfully. But there is a total of 9 queues in the terminal business process
