One of the inter-island connectivity in Indonesia is supported by the availability of maritime ports. The existence of a port is essentially to facilitate the transfer of goods between the modes of land transportation (inland transport) and the mode of sea transportation (maritime transport) as well as channel goods in and out of customs areas as quickly and efficiently as possible. However, to support the efficiency and effectiveness of port activities is still constrained by several existing problems. Some problems in port activities include Dwell Time and Equipment for supporting port activities. This study aims to optimize the utility of loading and unloading activities on the terminal container operating model by allocating resources and scheduling devices that are different from terminal operations by using Flexterm simulation software. Research has been carried out by making a container terminal model in Flexterm using parameters from the operational data of container ships with a capacity of 2226 TEUs with variations of quay crane. By increasing the number of resource units, especially the quay crane, can increase or decrease the utility of other resources. But it hasn't changed significantly. This applies to the trucks that have been simulated in this research model. By adding 2 quay cranes, this has an effect on time efficiency in loading and unloading operations. The utility at the container terminal is affected by the amount of resource allocation at the port itself. The ratio of the resource ratio must be adjusted according to the location or geographic location of the port.
