Abstract

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.

Abstract

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.

Abstract

Heat exchanger (HE) is a component of the main engine cooling system that plays a very important role in the process of changing the fluid temperature by exchanging the amount of heat with other fluids. The use of HE in the main engine cooling system should be considered in controlling after operation. HE performance can be analyzed using heat transfer analysis in the form of heat absorbed by HE (Q), LMTD and heat transfer coefficient (U). This study aims to analyze heat transfer in the form of calculations of absorbed heat, LMTD and heat transfer coefficient on the main engine HE KM Sumber Mutiara. This study measures the temperatures of fresh water and sea water entering and leaving the HE. In addition, measurement of water discharge and determination of the dimensions of the HE used for the main engine cooling system of KM Sumber Mutiara. This research shows that the highest heat value absorbed by HE (Q) is at RPM 1200 at 44.85 kJ/s, for the LMTD value at RPM 1000 at 45.69 oC and for the U value at RPM 1100 at 824 W/m2. oC. HE main engine KM Sumber Mutiara has not maximized its performance due to the fouling factor from sea water. The need for preventive maintenance and additional filters on the KM Sumber Mutiara Main Machine Heat Exchanger to increase the effectiveness of the HE.

Abstract

The impact of noise in the working area of fishing vessels should be understood, and effective noise reduction strategies should be identified to protect the health and performance of crew members in the workplace. This study aims to evaluate the level of noise in the working area of fishing vessels using a sound level meter during fishing operations. The study involved direct field data collection to obtain accurate and representative information on the noise levels experienced by the crew during fishing operations. Areas evaluated for noise levels include the engine room, deck, crew quarters, stern, and bow of the vessel. Data used for the study were collected from KM Nelayan Jaya, a fishing vessel equipped with a purse seine fishing gear, measuring 28.45 meters in length and powered by a 300 HP diesel engine. Noise levels were evaluated based on the IMO standard for noise exposure in the workplace, which recommends an average exposure limit of 80 dBA over 24 hours. The results of this study provide information on areas that exceed the specified standard noise levels and identify effective noise reduction strategies to protect the health and performance of crew members while improving the operational efficiency and overall sustainability of fishing vessels.

Abstract

The refrigeration system in the fishing process is important for maintaining the quality of the catch. However, the design of small-scale refrigeration machines is still not common, so it is an interesting study. Therefore, this study aimed to evaluate the design of small-scale fishing vessel refrigeration machines. Field studies are needed in machine manufacturing to observe the components required to match the refrigeration machine components onboard fishing vessels. This uses a direct observation method to determine the components of the refrigeration machine on the ship. Furthermore, the performance of the machines produced will be tested through the load cooling process. Parameters determined in the performance test include monitoring temperature (suction and discharge), pressure (suction and discharge), evaporator temperature, load temperature, COP (Coefficient of Performance), and compressor power. Refrigerant temperature measurement uses an insulative principle so that ambient temperature does not affect it. The result is that the machine produced has a capacity of 35 l or 15 kg of load. Meanwhile, in the performance test, the COP and electrical power generated while cooling the load for approximately 4 hours were 2,42 and 507 W, respectively. The results of this design were successful and did not experience failure. The significanceof this study can be used as a reference source for making cooling machines for storing the catch of small-scale fishermen.
