Research conducted at the Terminal for Self-interest PT. Kawasan Berikat Nusantara (Persero), the port of Marunda is a place where the ship is going in and out and it is affected by the tides of the sea, which is caused by the limitations of the depth of the groove and the pool of the port, so that ship services are not optimal. This study used quantitative method. The main thing examined in the ship service is waiting time for the ship in the queue. To find out the waiting time of the current condition using statistical analysis on average (mean), while waiting time for optimal conditions or without any obstacles when the ship is going in and out by using the discipline queuing theory analysis First Vacant First Served. The difference in waiting time is used to determine the amount of the operating costs of the ship and the value of interest in the cargo during the queue. Dredging is a way to overcome the problem of the limited depth of the port's grooves and ponds, therefore it is necessary to know the costs of dredging and maintenance of the port's grooves and ponds. Then the operating costs of the ship and the value of interest in the cargo during the queue, compared to the cost of dredging and maintenance of the port and pond pool. The results showed that dredging was still more profitable compared to current conditions where the waiting time decrease was 78.07% for dry bulk loads and 36.29% for liquid bulk loads.
