Abstract

PT. Sinergi Perkebunan Nusantara plans to use the Lampia port for shipping of Crude Palm Oil (CPO). Lampia Jetty has more than ten years old so that its carrying capacity against external loads may have decreased. Therefore for the operational safety of the ship, it is necessary to study the engineering capacity of the pier. By knowing the engineeringcapacity of the existing pier, the maximum ship dimensions that can be served by pier can be determined. This study began with the collection of supporting data consisting of ship data, hydro-oceanographic data, bathymetry data, pier structure data and earthquake data. Furthermore, the load calculation that works on the pier consists of dead and live loads, earthquake loads, ship impact loads, current loads, wave loads, ship tensile loads and wind loads. After the load calculation is completed, then the pier modeling is done using SAP2000 software followed by inputting the load using aspecific combination of loading and running model. In this study the dimensions of the ship were varied namely 500 ton, 700 ton, 1000 ton, 2000 ton and 3000 ton. The indicator used in assessing the technical capacity of the pier is the safety factor (SF) as a function of the ship DWT. Based on the results of the strength analysis of the pier structure, it wasfound that the existing pier is capable and safe serving ships with a size of 27 1027 DWT if it uses a safety factor (SF) 1.5. Whereas if use the safety factor (SF) 2.0, the existing pier structure is capable and safe to service ships with a size of ≤ 510 DWT.

Abstract

Bantaeng Port already has a dock for the loading and unloading goods and passengers. The problem is, the port cannot be operated optimally because of the large wave height at the dock so that the loading and unloading process is not optimal. The Bantaeng Port Master Plan document recommends the construction of a breakwater. One type of breakwater that can be applied is hanging breakwater. This study analyzes the dimensions of hanging breakwater based on environmental data. The study began by collecting data on deep-sea waves and related documents. Deep sea waves are analyzed to obtain wave parameters at the building site. This structure will be placed at a depth of 20 m. After the wave parameters at the location of the structure are known, then calculate the transmission coefficient using the equation developed by previous researchers [2]. The transmition coefficient is further used to calculate the wave behind the structure. The wave behind the structure must be smaller or equal to the required wave height [3]. The results obtained shows that the higher the wave in front of the building is Hi = 1.79 m, the wave height behind the structure is required is Ht = 0.7 m and the transmission coefficient is Kt = 0.8. The width of the building in the direction of wave propagation can be calculated using the equation L= 46.757e-0.08D.
