Masroeri 1 , Eddy Setyo Koenhardono 2 , Fathia Fauziah Asshanti 3 Abstract container crane electrification is a re-powering process of container cranes from diesel to electricity. In electrification process, it is required an analysis of electrical power consumption that is needed in the operational of container crane. It aims to determine whether the amount of electrical power that is supplied by PLN can be optimally used in the operational of container crane to do loading and unloading activities. To perform the analysis of electrical power consumption, it is required various data and calculations. The required data are container crane specifications and other electrical equipment specifications, the amount of electrical power that is supplied by PLN, also the single line diagram from the electrical system at the port. While, the calculations that is needed to be performed are the calculation of electrical power load in motors and other electrical equipments, the calculation of nominal current and start current, the selection of cable and busbar, and the calculation of wiring diagram junction power. From the calculations that has been done, then the next step is to do the load flow analysis simulation by using software simulation, so an accurate and effective load flow analysis can be obtained to optimize loading and unloading activities at the port. The result of this research, it can be seen that container crane electrification will give advantages in both technical and economical for the company and for the ship, such as accelerate the loading and unloading time of containers and reduce idle time, especially in the operational of diesel generator.

INTRODUCTION 1 T he idea of green port is now being intensively implemented by all port management of all ASEAN countries for the last five years, in both developed and developing ports. The application of the idea of green port at some ports in developed countries in Europe and Asia is a part of the effort to minimize the level of marine pollution, air pollution and other environmental damages that are caused by loading and unloading activities at the port. Container Terminal Surabaya (TPS Company) is a company that handles the provision of container terminal facilities, both for domestic and international trade. TPS Company holds a very important role in economic growth and trade, especially for businessmen in the eastern part of Indonesia. Because of that, the demand of port services that is offered will increase. The increasing demands of port services will be certainly increasing port activities that will impact on increasing pollution around the port, such as air pollution and water pollution [1]. Therefore, it needs an effort to create a green port to overcome the environmental damages that are inflicted by various activities at the port. In order to support the implementation of the idea of green port, Container Terminal Surabaya is now conducting container crane (CC) electrification on all units of container crane and some components and other main equipments. Electrification is a powering process on an equipment by using electricity. The benefits that A.A.

In this research, an analysis for the requirement of electric power consumption that will be used in the operational of container crane will be conducted. There are three ways to determine the electric power consumption that will be used in this research, there are by using empirical formula, electrical load analysis and load flow simulation by using software simulation. II. METHOD A. Loading and Unloading System at Port Loading and unloading system at port is all components or cargo handling equipments that are used to support loading and unloading cargo activity, from ship to port or otherwise. While, the loading and unloading activity at port is an activity of unloading goods from aboard of the ship by using crane and sling to the nearest land on the edge of the vessel, commonly known as dock, then from the dock by using a lorry, forklift or stroller, inserted and arranged into the nearest warehouse that is designated by the port officer [2]. The loading and unloading activity can be categorized into three kinds, there are: a. Stevedoring Stevedoring is an activity of unpacking goods from ship to dock/barge//truck or loading goods from dock/barge/truck into the ship by using a ship’s tow or land’s tow. b. Cargo doring Cargo doring is an activity of releasing goods from ropes/nets (tackle) at the dock and transporting goods from dock to warehouse/stacking field and then arranging in the warehouse/stacking field or otherwise. b. Receiving/Delivery Receiving/delivery is an activity of moving goods from a heap/hoarding place at the warehouse/stacking field and handing it over
