<![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[The source of electrical energy is one of the main components in everyday life. The development of technology today requires all people to be able to take advantage of renewable energy, one of which is solar energy. The solar panel is an energy conversion machine that can produce electrical energy. Coastal communities have an abundance of solar energy sources that can be utilized by solar panels as alternative electrical energy in the aquaponics system that has been built. The majority of the people of Tanjung Palas Village, Dumai City, are fishermen. So that there is a need for additional economic income besides being a fisherman. On the other hand, the community still does not understand the operation and maintenance of solar panels due to knowledge problems. Therefore education and the installation of solar panels as a source of aquaponic electricity are alternative solutions offered to the community. The educational activity of solar panels as a source of aquaponic electricity is carried out in collaboration with CSR PT Pertamina RU II Dumai with the Dumai Marine and Fisheries Polytechnic. The result of this activity is that the level of understanding of participants from per category always increases. The knowledge category increased from 39% of participants to 93% of participants, the operating category increased from 14% of participants to 94% and the care category increased from 14% of participants to 95% of participants. In addition, the level of satisfaction of the participants shows that 25% of participants are very satisfied and 75% of participants are satisfied with this activity. Recommendations for the results of activities that have been carried out are that there is a need for follow-up activities so that the community can better utilize solar panels as alternative electrical energy.]]>

<![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. Recommendations for service activities in the form of processing fishery products that can be practiced directly with the community will be better in the future.]]>

<![CDATA[Plastic waste is one of the environmental problems in Indonesia. Plastic waste is a type of waste that is difficult to decompose, so it needs special handling for processing the problem. One alternative offered is by making a plastic chopper machine. One of the manufacturing of a machine is to design and analyze the components used. The blade is one of the important components of a plastic chopper. Model simulation of the blade itself needs to be done to analyze the performance of the blade during the performance of the machine. Simulation modeling is done using CAE software.. The form of meshing in the blade model is using tetrahedral and the meshing ratio is close to 1. The results obtained from the blade modeling process are the maximum Von mises stress on the loading of 300N, 500N, and 700N respectively at 6.752 x 10-3 MPa, 2.845 x 10- 3 MPa and 1,575 x 10-3MPa. While the amount of displacement in the variation of loading 300N, 500N, and 700N respectively has a value of 6.752 x 10-2 mm, 1.125 x 10-1 mm and 1.575 x 10-1 mm. The safety factor in this simulation is produced which has a value of 15, which means it is safe for all loading variations because it has a value of more than 1.]]>
