Dumai is located on the eastern coast of Sumatra, facing directly onto the Malacca Strait, which is one of the busiest maritime routes in the world. This situation has led to Dumai having a lot of potential for development, one of which is the Dumai Port managed by PT Pelindo Regional 1 Branch Dumai, with several ports managed by the community. Palm Kernel Expeller (PKE) and Palm Kernel Shell (PKS) are the main dry bulk commodities at Dumai Port, which are byproducts of palm oil processing and are widely exported to East Asia and Europe. This Final Project discusses the planning of a dry bulk dock at Dumai Port, Dumai City, Riau Province. The dock design references Technical Standards and Commentaries for Port and Harbour Facilities in Japan, British Standard, Indonesian National Standards, American Society of Civil Engineers, and Port Designer's Handbook. The scope of this Final Project includes secondary data processing, structural load calculations, determination of wharf dimensions, structural modeling of the wharf using SAP2000, design of reinforcement for wharf structural elements, and soil bearing capacity analysis. The modeling results need to be checked to ensure they meet the UCR value within the range of 0.7 to 1 and that deflection values do not exceed permissible limits. The internal forces and reaction results from the modeling will be used for reinforcement design calculations and soil bearing capacity analysis. The designed dock dimensions are a length of 190 meters and a width of 35 meters. The wharf elevation is +5 meters above Lowest Water Spring (LWS), and the water depth is approximately -11 meters below LWS. The wharf structural elements consist of slabs, beams, pile caps, and piles. Two types of pile caps are designed: standard pile caps and fender pile caps. Based on structural analysis, cylindrical piles with a diameter of 700 mm and a thickness of 17 mm are proposed, with plans for driving them to a depth of 44 meters below the seabed. The outcome of this Final Project is a design plan that includes wharf structural dimensions, ship berthing and mooring facilities, dimensions of structural wharf elements, design of reinforcement for structural wharf elements, and soil bearing capacity analysis.
