Indonesia is the largest archipelagic country in the world, with thousands of island clusters and millions of kilometers of surrounding sea. This geographical condition plays a significant role in shaping a strong Indonesia maritime culture One of these maritime cultures is the utilization of the sea as a means of transportation to establish connectivity between islands in Indonesia. Therefore, Indonesia must maximize the utilization of the maritime transportation sector while continuously developing it. One area in Indonesia that heavily relies on maritime transport is Pasipalele Village, which is home to Pasipalele Port. Pasipalele Port serves as a local feeder port situated in Pasipalele Village, South Wast Gane District, South Halmahera Regency, North Maluku Province, Indonesia. The port handles the loading and unloading of goods and passengers. The main commodities handled at this port include copra, daily necessities, construction materials, and fisheries products. Consequently, Pasipalele Port has contributed to accelerating economic growth and improving the welfare of the population in South Halmahera Regency. In 2019, Pasipalele Port's crucial role as a supporter of the economy in South Halmahera Regency was disrupted due to an earthquake disaster that caused damage to the port's dock facilities. Given its pivotal position in facilitating community mobility, reconstruction and rehabilitation of the port facilities became necessary. The jetty dock structure designed with a deck on pile configuration was aligned with the existing dock structure. The method used in planning the jetty deck on pile type berth structure consists of processing secondary data, calculating the load of the berth structure, designing the berth and trestle structure, modelling and analyze the structure, designing the reinforcement of the structural elements of the pier, and analyze the soil bearing capacity. The initial stage of the design is the collection and processing of environmental data, such as the tides, currents, winds, waves, and soil. Operational data processing is also carried out to obtain the load on the berth structure. Preliminary design is carried out to obtain the minimum cross-sectional dimensions required based on the initial calculation. The cross-sectional dimensions are modeled on the SAP2000 software. The results of the modelling will obtain the value of the unity check ratio (UCR), the deflection of the structure, the forces in the beams and slabs, as well as the reaction to the placement of the piles. The unity check ratio (UCR) value needs to be in the range of 0.7 to 1.0 in order to be in optimum conditions, and the deflection value must meet the design criteria used. The internal structural forces in the optimized design are used to design reinforcements of the structural elements. The analysis of the bearing capacity of the soil is conducted to obtain to calculate the required piling depth based on the soil bearing capacity so that the structure can withstand the load based on the reaction of the pile placement obtained from the modelling. The design of the berth structure in this Final Project refers to existing standards, including the Technical Standards and Commentaries for Port and Harbour Facilities in Japan published by The Overseas Coastal Area Development Institute of Japan (OCDI) in 2009, British Standard (BS), and Standar Nasional Indonesia (SNI), American Institute of Steel Construction (AISC) standard, American Concrete Institute (ACI) standard, American Society of Civil Engineers (ASCE) standard, American Association of State Highway and Transportation Officials (AASHTO) standard, and other valid supporting standards and product catalogues. The final result of the design strukture of the berth in this final project is the dimensions of the pier and trestle structures, the dimensions of the structural elements, and the dimensions and depth of pile driving.
