Abstract

Siltation of shipping channels is a problem that can increase shipping safety and security risks and hinder economic activities. One of the causes of siltation is sedimentation, which is the process of deposition solid particles in the form of sand and rocks so that it requires regular maintenance. Especially in the Perak River shipping channel that has occurred quite significantly over the past few years and there has been no dredging until now. The occurrence of sedimentation has a great impact on the operational activities of shipyard companies located along the Perak River shipping channel. The purpose of this study is to find out what are the impacts caused by the sedimentation of the Perak River on shipyard operations. This type of research is a Quantitative research using the SPSS application. The sample of this research is an employee at the shipyard company PT. Dumas Tanjung Perak Shipyard and Pelni Surya Shipyard. In this study, a simple linear regression data analysis technique was used, then the result of the equation Y = 5.943 + 1.112X was obtained. The results of this study show that the impact of sedimentation of shipping channels has a positive and significant effect on shipyard operations. The impact of siltation such as a reduction in the number and size of vessels that can pass through the channel and also increased operational costs for shipyard companies and ship owners due to process delays when waiting for the waters to be independent in the highest tide conditions.

Abstract

The Main Mover Diesel Engine or Main Engine on a ship is the main device responsible for moving the ship forward and backward. The diesel engine fuel system, which includes the Bosch Pump, is a critical component in maintaining the engine's performance by providing the fuel necessary for combustion and propulsion of the vessel. The injector, which is used to spray fuel into the engine cylinder, is an important part of the system that supports the efficient combustion process in the main engine. The method used is a quantitative method which includes the collection and analysis of numerical data. By conducting surveys, experiments, or secondary data analysis, researchers can find patterns or generalizations in a larger population. By using quantitative methods, it will be possible to determine the cause of the decrease in Bosch pump pressure on the ship MV.Tanto Bersinar. The analysis of running hoaurs of puncture valve on the fuel injection pump for cylinder 1-8 demonstrates that the wear of puncture valve especially in cylinder 2 with 4.970 hours approaching the planned maintenance system (PMS )limit of 5.000 hours significantly affects injection pressure stability ,combustion,quality ,and main engine officiency ,which can be restored throngh critical component replacement,inspections close to PMS and injection pump recalibration.
