Abstract

Lubrication is one aspect that must be paid attention to, remembering that if there is a delay in lubrication or imperfect lubrication, it will result in damage to the parts that rub together. Low lubricating oil pressure is one of the factors causing imperfect lubrication in the engine. The purpose of lubrication for the performance of the main engine is to reduce friction between other components of the main engine. This research was carried out at MV. Manalagi Dasa, the method used in this research was the Fishbone Diagram. The problem formulation of this research is what causes an increase in the temperature of the lubricating oil on the main motor and what is the impact of increasing the temperature of the lubricating oil on the main motor. Based on research that has been carried out, there are several factors that cause less than optimal lubrication of the oil cooler on the main engine, namely engine factors including damage to gaskets, human factors, namely the lack of understanding of the driver about the lo cooler, operational and maintenance method factors, namely incompatibility in implementing the PMS (Plan Maintenance System) as well as environmental factors, namely dirty sea chest filters. Efforts made include repairing or replacing gaskets on the lo cooler plate, the importance of the machinist's understanding of the lo cooler, implementing PMS (Plan Maintenance System), and cleaning the sea chest filter.

Abstract

An oily water separator is an auxiliary engine on board that is used to prevent the mixing of oil and water with density differences. The oily water separator is very important on board for the separation of the ship's bilges from oil content which can pollute the marine ecosystem. This matter also fulfills the requirements of MARPOL 73/78 Annex 1 when the researcher carried out a sea project on SS. Golden Isaia, The researcher found the abnormality of the oily water separator. There was a decrease in its discharge volume, in which the normal flow was 5 m 3 / hour, which became 1 m 3 / hour. The purpose of this research was to determine the causal factor of oily water separator decreasing discharge volume on SS. Golden Isaia, evaluate the impacts, and the efforts to solve this oily water separator decreasing discharge volume on SS. Golden Isaiah. This research uses a descriptive qualitative method by applying a fishbone diagram analysis model. Data collection techniques include observation, interviews, and literature review. The interviews involved three informants, there chief engineer the one responsible for all machinery on board, the second engineer whose responsible for the oily water separator, and oiler 1 as the second engineer's assistant. The research results conclude that the causal factors of oily water separator decreasing discharge volume such as the lack of pressure of the oily water separator feed pump, dirty process filter due to accumulated dirt, and unavailability of oily water separator maintenance history. The efforts to solve this oily water separator decrease discharge volume on SS. Golden Isaia such as the change of a feed pump set with the new one, cleaning the strainer and replacing the filter bag, and the documentation of repair and maintenance.

Abstract

The main engine Lubricating Oil (LO) standby pump is crucial for smooth ship operations. Therefore, it is essential that this equipment is well-maintained. However, future problems can arise and disrupt ship operations if the maintenance schedule is not followed. The main engine lubrication system can be disrupted due to a damaged L.O. standby pump, which can interfere with the smooth lubrication of the main engine. Based on field observation during a 12-month and 2-day sea project on board MT. Klawotong, the researcher experienced overheating of the L.O. standby pump. When the ship entered bad weather on the voyage from Wayame to Tual, it disrupted the crew's comfort on board while working. The purpose of this research is to determine the causal factors, the impact of overheating on the pump, and efforts to prevent overheating of the L.O. pump. This study uses a qualitative descriptive method by conducting interviews and direct field observations. Data analysis technique using SHEL (Software, Hardware, Environment and Liveware). By interviewing the Chief Engineer, 2nd Engineer, and 4th Engineer, this study states that overheating of the main engine L.O. standby pump is caused by a damaged rubber coupling, a damaged oil seal, and abnormal vibration in the pump. The impact of these factors will reduce pump performance, reduce lubrication in the main engine, and reduce pump performance. Preventive measures can be done by implementing routine maintenance on the pump and cleaning the oil filter regularly. Cleaning dirt adhering to the oil filter using a brush, solar, and following the procedures correctly and properly.

Abstract

Keselamatan Pelayaran bagi nelayan dan ABK kapal ikan perlu menjadi perhatian lebih, hal ini disebakan karena nelayan /anak buah kapal pada kapal ikan yang bekerja di tengah laut umumnya belum memahami tentang keselamatan pelayaran, kebiasaan nelayan/anak buah kapal pada kapal ikan bekerja hanya dengan syarat mengumpulkan foto copy KTP tidak semua anak buah kapal dibekali dengan kompetensi kepelautan yang sesuai dengan peraturan. Nelayan/anak buah kapal pada kapal ikan sudah semestinya menyadari segala sesuatu yang berkaitan dengan keselamatan kerja di laut,bagi nelayan / pekerja kapal ikan yang belum terampil tentunya perlu dibekali dengan pelatihan dan ketrampilan sehingga layak untuk melaut

Abstract

Crank pin bearing consist of two plates with very smooth surfaces made from various metal layers with different hardness levels. This component is crucial because it supports the performance of the connecting rod on the crankshaft. It is installed to reduce friction occurring during combustion between the crankshaft and connecting rod. After combustion, the translational force of the piston is converted into rotational force on the crankshaft. The purpose of the research is to understand the factors, impacts, and mitigation efforts related to the damage of metal bearings on the auxiliary engine of MT. Salmon Mustafa. The research method used is qualitative descriptive with fishbone analysis techniques, where data is obtained from observations, interviews, and documentation. Interviews were conducted with the Chief Engineer, Second Engineer, and Third Engineer. The results of this study indicate that the causes of metal bearing damage on the auxiliary engine are suboptimal PMS implementation, inappropriate metal bearing components, decreased lubrication oil pressure, suboptimal lubrication oil cooling, presence of deposits on components, and corrosion or wear. The impacts of these factors include reduced performance of the auxiliary engine, imbalanced crankshaft rotation, and damage to the connecting rod and crankshaft. Efforts to prevent damage to the metal bearings of the auxiliary engine include increasing lubrication oil volume, cleaning the lubrication oil cooler, adjusting LO temperature and LO pressure, cleaning the lubrication oil filter, routine checking of the metal bearings of the auxiliary engine, and monitoring the running hours of the auxiliary engine lubrication oil.
