Abstract

Depreciation (losses) is a common problem and continues to occur when the ship finishes loading or unloading at the port. This problem occurs because of differences in calculations between the ship and the land where the calculation results exceed the tolerance limit given by the company. This shrinkage can occur if the temperature between the two tanks is much different. In reducing the risk of such depreciation, it is necessary to control depreciation (losses) while on board the ship. Control can be done by checking the temperature on the land tank or ship tank. The different temperatures between land tanks and ship tanks are caused by different weather and climatic factors. Depreciation control can also be done by monitoring the volume of oil on each movement of oil from land or to ships. This control aims to control oil shrinkage from the specified tolerable loss, by reducing, maintaining and tackling, thereby increasing profits for the company. No onshore tank capacity can also hamper the loading and unloading process at the port. The loading and unloading process activities at the port, especially the land side, are the full responsibility of the Loading Master, if there is no ullage in the land tank, it must confirm or contact the ship, in this case the officer in charge and the officer in charge of the cargo because otherwise it will cause overflowed in the land tank and became a new incident. The Loading Master must also stop the loading and unloading process at the port because there is no capacity in the land tank, therefore the loading and unloading process is hampered and cannot be completed on time. Because the operation of the port is not only owned by ships, in order to streamline time, the port party coordinates with the pilot and the Loading Master regarding this kind of incident, they must remove the ship and ask the ship or the captain to dock temporarily to wait until the cargo on the land tank is sold. This is because the land side cannot predict when the cargo will be moved or distributed via tank trucks, it takes 1 hour or more, sometimes days to move the cargo.

Abstract

The exhaust valve is a component that functions apart from being a way out for combustion residue in the combustion chamber, it also plays a role so that the combustion chamber remains airtight during the compression stroke and the effort stroke. The performance of the exhaust valve greatly affects the power generated by the auxiliary engine. A tight exhaust valve is very important so that the combustion products in the cylinder do not leak into the exhaust manifold so that the performance of the auxiliary engine becomes optimal and the role of the auxiliary engine as the heart of a ship can supply electricity on board properly. The research method used is qualitative with qualitative descriptive data analysis techniques and data collection techniques through observation, interviews, and documentation studies. An indication of damage to the exhaust gas valve is the high temperature of the exhaust gas, as well as abnormal engine sound. After analysis, several causes were found, namely the use of inappropriate spare parts, fatigue in the exhaust gas valve, incomplete combustion in the combustion chamber. Then solve the problem which results in optimal exhaust valve performance so that the performance of the auxiliary engine is good.

Abstract

Crew Manning Agency is a division that only takes care of crew for ship owners overseas. PT. Jasindo Duta Segara uses International Safety Management (ISM) which aims to be the "Best Crew Supplying Agent in the World" to meet the expectations of the company and crew perfectly. PT. Jasindo Duta Segara will not let owner or crew calls go unanswered. Don't let the owner be served without commitment and don't let the crew fail in their performance. Before joining PT. Jasindo Duta Segara, the crew made a selection at the company using various tests such as: academic, psychological tests, marlin tests, in order to determine the ability of ship crews who want to join PT. Jasindo Duta Segara. The process of changing the crew is very influential in terms of promotion and wages of ship crews. The crew on duty on one ship are Master, Chief Officer, Second Officer, Third Officer, Bosun, Able Seaman, Ordinary Seaman, Chief engineer, First Engineer, Second Engineer, Third Engineer, Oiler No. I, Oiler II, Waper, Chief Cook, and Mass Man. All of these crews are involved in the crew change process in which the promotion of crew vacancies affects the crew change process, in this case resulting in a lack of promotion of crew vacancies that are widely spread through the media and an inconsistency in the crew change process which can disrupt and hinder ship operational activities so as not to eat up the crew. longer time.
