<![CDATA[The fuel system is one of the main engine support systems which is very important in the operation of the KM Sidomulyo main engine. Main engine on ships are operated 24 hours a week or more. The operation main engine needs special treatment of the components on the main engine to prevent failure during operation. Failure Mode and Effect Analysis (FMEA) is a method that can be used to identify the priority scale in maintaining a machine by evaluating the risk of failure that occurs on the machine. This study applies FMEA to determine the priority scale for the maintenance of the KM Sidomulyo main engine fuel system. The results of the identification using FMEA, namely the injector and fuel filter components are components that must be prioritized for maintenance. The Risk Priority Number (RPN) values of the injector and fuel filter components are 192 and 168, respectively. Maintenance priority is based on the component RPN value is above the critical RPN value of the main engine fuel system and includes the priority component on the Pareto diagram. The type of maintenance applied to the injector component is checking dirty fuel which can cause the injector to operate less optimally. While the fuel filter component is cleaning the deposits on the fuel filter cartridge. It is recommended that the inspection of other components be carried out so that the condition of the main engine fuel system has good reliability.]]>

<![CDATA[Fisheries products from marine sector really need to be considered because Indonesia, especially in the waters of Dumai City, has abundant fish resources of up to 571 tons/year. Diversification of processed fish is a solution so that processed fish can be consumed by the community. On the other hand, the local community of Pelintung Village, Dumai City, still lacks appropriate technology that can improve the quality of processed products from diversification. Some processed fish products are of poor quality. Community service activities aim to provide knowledge transfer and use of oil draining machines so that people can improve the quality of processed fish or non-fish. This community service activity uses the method of applying the use of an oil draining machine in Pelintung Village. The essence of this event is the delivery of theoretical and practical material about oil draining machines. The pre-test was carried out before the material was delivered and the post-test was carried out after the material was delivered. Filling in the satisfaction index is done along with filling out the post-test. The results of this activity stated that the community was very enthusiastic as the percentage of correct answers for the pre-test and post-test increased. The results of the pre-test and post-test in the knowledge, operation and maintenance categories increased to 75%, 84% and 100%, respectively. The satisfaction level of participants was also stated to be satisfied with the percentage of 61.7% and getting benefits from this community service activity. This activity must continue to be evaluated so that when holding similar activities, it can be more effective, efficient and sustainable.

<![CDATA[The propeller was an important component in the fishing vessels marine propulsion system. Brass was widely used as a fishing vessel propeller. Brass was chosen because it has good mechanical properties and good corrosion resistance. The content of seawater in Indonesia has levels of 3% – 3.5% NaCl. In addition to the level of Ion Cl-, environmental factors can affect corrosion rate of material or metal. The environmental factors that affect the corrosion rate are the level of salinity, pH, DO, temperature and TDS. The objective of the present work was to explain the corrosion rate of brass in artificial seawater in Indonesia with exposure time. The material used for research is fishing vessel propeller commercial in Indonesia market. Measurement of the corrosion rate of brass used the principle of weight loss according to ASTM G31-72 (2004). During the corrosion test, the artificial seawater solution was tested for its pH and salinity quality over time of immersion. The result of immersion brass in the artificial seawater shows that the corrosion rate decreases in 1-to-10-days exposure time due to the increase in salinity levels above 30‰. While the results of exposure time immersion above 15 days tends to increase the corrosion rate due to a decrease in pH level. pH level of seawater depends on the environmental conditions and tends not to change significantly.
