Abstract

Transportation is one of the supporting factors for the smooth running of the economy in a country. One of the transportation is sea transportation because it is more effective and efficient. For this reason, the ship which is the main factor in the smooth operation of sea transportation must be prepared in its operation, the main thing that can support the smooth running of a ship is the smooth operation of the main engine. In general, the main engine on board the ship uses a diesel engine type, and the starting system uses compressed air where the compressed air is produced by the compressor auxiliary aircraft, so it can be said that the compressor has an important role in the operation of the ship. The compressor is one of the aircraft that is used to compress low-pressure air with higher pressure. During the operation of the main engine when the motion occurs, sometimes there are obstacles or obstacles that cause damage to the air compressor, so the compressor cannot work optimally. This results in the process of filling the main engine starting water for too long and can affect the smooth process of movement. The purpose of this study is to find out the obstacles or obstacles that can interfere with the main engine of the composer. The method used by the author in this study uses descriptive qualitative with several methods, namely, approach methods and data collection techniques. In the discussion in this study the author by finding several solutions to problems carrying out maintenance on engine room blowers and routines on the compressor as well as cleaning rust on the plunger and parts of the auto drain solenoid valve. The conclusions obtained in this study must maintain the air temperature in the engine room and always clean the high-pressure valve and low-pressure valve and pay attention to the compressor temperature so it doesn't get too hot because it can produce worse air.

Abstract

The aim of this research is to determine the design of a solar cell power generation system for utilizing fuel on ships at PT. Universal Manunggal Chakra. In this research, the type of research used is Research and Development. Seeing these things, researchers are interested in developing a solar cell power generation system to supply electricity on ships and applying a solar cell power generation system to supply electricity on ships. The results of the research state that the results of the manufacture and development of a prototype solar cell power generator can be concluded that the product is suitable, so it can be applied on ships. This can be proven from the test results by having a percentage of 96.25% in the appropriate category, so that the power generator prototype can supply electricity to the diesel generator on the MT.Hendropriyono III ship.

Abstract

A turbocharger is an auxiliary engine that functions to supply air into the cylinder and in general every turbocharger has two sides, namely, the compressor side and the turbine side, the rotation of the turbocharger is generated from the remaining exhaust gases from combustion in the cylinder which goes to the turbine side of the turbocharger and produces rotation. on that side and also rotates at the same speed on the compressor side of the turbocharger. The amount of air that will enter the cylinder depends on the rotation of the turbocharger itself, if the rotation of the turbocharger is too fast it will produce too much air in the cylinder which results in knocking or knocking on the main drive engine, whereas if the turbocharger rotates too slowly it will result in too little quantity of air resulting in a misfire or failure of combustion in the cylinder. To determine the rotational speed of the turbocharger, we need a tool that can regulate the quantity of the remaining exhaust gases from combustion in the cylinder, namely the waste gate valve. When the writer carried out the sea practice, the writer experienced various interesting things about the waste gate valve, such as the opening that did not match the degree of the waste gate valve to the difference in the indicator readings on the waste gate valve. In this case the author will analyze the cause of the imperfect supply of air entering the cylinder caused by the non-optimal performance of the waste gate valve.
