The increasing need for vehicles brings up several problems for loading and unloading companies due to the dominance of cargo vehicles in the car yards, the increasing cargo traffic inside the port every year, the tardiness of export documents from the Shipper / EMKL owners and the increasing intense competition of similar business fields on the same location. By using Evaluation Review Technique Program / PERT , the researchers would like to find out the process of loading and unloadingvehicle , the factors that influence the time for loading and unloading vehicle and the optimal time in scheduling loading and unloading vehicle. The results show that the time for loading and unloading vehicle is carried out within 22:25:00 25 minutes and the critical path at 21:40:00. The factors that influence the length of loading and unloading vehicle are (a) Delay in providing export documents, (b) Simple system for making stowage plan documents, (c) Lack of Human Resources in the process of loading and unloading vehicles. The optimal time that can be taken is 14:00:00 with opportunities based on a normal table of 0.99988, which means that there is a chance of 99.99% of the process loading and unloading vehicles can be completed in the optimal time.
