Along with population growth and economic growth hence also increased requirement of electricity. Steam Power Plant (PLTU) with coal as the energy source is the most widely used type of power plant in Indonesia. The case study used in this thesis is a 1000 MW steam power plant in Cirebon that requires an unloading wharf facility in the Java Sea to accommodate a 15000 DWT vessel. The construction of a wharf in the sea encountered some difficulties, one of them is the different environment conditions between marine and the land. Considering the ease of construction process, using precast concrete as the upper wharf structure is one of the solution to solve this problem. By using precast concrete methods, most of the work of concreting done at the sea can be done in the the land. <br /> <br /> Based on the environmental data, plan ship data, and operational data, the wharf structure is designed using The Overseas Coastal Area Development Institute of Japan (OCDI) and being analysed with SAP2000 software. The output of structural analysis using SAP2000 software is Unity Check Ratio (UCR), structure deflection, internal force, and placement reaction. The modelling results are used to design the reinforcement of structural elements are beams, plates, and pile caps. Based on the result of the reinforcement, the design of precast concrete elements that include beams and plates can be done. The precast concrete elements then analysed with three analysis which are lifting analysis, installation analysis, and pedestal analysis. The design of the wharf is referenced to SNI 7833: 2012 and SNI 2847: 2013. The modelling results are also used to analyse the axial capacity for pile foundations.
