Indonesia, as an archipelagic country with thousands of islands, heavily relies on maritime transport systems to connect various regions and support national economic growth. In this context, the design of a general cargo berth at Kilo Port, West Nusa Tenggara, is important. This thesis aims to design a berth that meets both international and national standards, including British Standard, The Overseas Coastal Area Development Institute of Japan (OCDI), Standar Nasional Indonesia (SNI), and Shore Protection Manual. The study encompasses various aspects of design, including secondary data processing, structural element modeling using SAP2000 software, reinforcement calculations, and soil bearing capacity analysis. Modeling with SAP2000 is conducted to determine the optimal Unity Check Ratio (UCR) between 0.7 and 1 and to ensure that structural deflection remains within allowable limits. The results from the modeling will be used to measure bearing reactions, which are crucial for soil bearing capacity calculations. The berth design involves primary dimensions of 112 meters in length and 12 meters in width, with an elevation of +3.4 meters from LWS and a depth of -7 meters from LWS. The berth structure includes elements such as plates, beams, piles, and pile caps. The piles are planned to have a diameter of 590 mm and a thickness of 14 mm, with depth determined based on soil bearing capacity analysis showing up to -28 meters from the seabed. The trestle, serving as a link between the berth and the mainland, has dimensions of 80 meters in length and 8 meters in width, and includes structural elements such as plates, beams, piles, and pile caps. The planned piles for the trestle have a diameter of 430 mm and a thickness of 12 mm, with pile depth of -18 meters from the seabed. Additionally, to connect the trestle with the mainland, a causeway is planned with a length of 150 meters and a width of 8 meters. This causeway will use sand for embankment and quarrystone for the cover layer. The structure will also be divided into a structure head, planned to extend 25 meters from the trestle, and a structure trunk, planned to extend 125 meters from the mainland.
