2021 – Design of Deck on Pile Cargo Berth Structure in Ketapang, West Kalimantan

Abstract: Indonesia is the biggest archipelago country in the world. With thousand islands separated by the sea, it becomes a challenge dor Indonesia to distribute logistics effectively. Based on PP 61 of 2009 the port hierarchy in Indonesia is divided into; Main port, collecting port, regional feeder port, and national feeder port. Ketapang Port is categorized as a local feeder port, which serves to serve loading and unloading cargo from and to Ketapang Regency. The purpose of this Final Project report is to design the structure of the Deck On Pile Cargo Pier in Ketapang Regency, West Kalimantan. The scope of the design consists of determining the dimensions of the pier and trestle as a link between the pier and the mainland, structural modeling, design of reinforcement for structural elements, and the bearing capacity of the soil. Ketapang port is designed to be able to serve cargo ships with a weight of 1000 DWT, dimensions of length of 75 m and width of 10 m with a pier floor elevation of +3.5 m and a water depth of 4 m. Trestle has dimensions of 84 m long and 5 m wide. Structural modeling is done using SAP2000 with the optimum design criteria being a structure with a UCR (unity check ratio) value in the range of 0.8-1 with a deflection that met the permit. The UCR value obtained for the pier structure is 0.87 and for the trestle structure is 0.80. The internal force obtained from the SAP2000 output will be used to design the reinforcement of structural elements, while the pile reaction value will be used for analysis of soil bearing capacity where the pier pile depth is 28 m and the trestle pile depth is 20 m.
