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

Sistem pelumasan adalah bagian dari salah satu sistem pendukung untuk melumasi komponen mesin pada mesin induk kapal penangkap ikan. Pengoperasian mesin induk pada kapal penangkap ikan memiliki durasi 24 jam selama 1 minggu hingga 1 bulan. Fenomena tersebut menyebabkan pengoperasian mesin secara terus menerus dapat menyebabkan penurunan kinerja bahkan kegagalan pada mesin. Beberapa kegagalan mesin induk dapat membahayakan awak kapal dan kapal itu sendiri. Oleh karena itu pemilihan perawatan pada komponen kritis sangat diperlukan. FMEA adalah salah satu metode yang sering digunakan untuk mengidentifikasi penyebab dan dampak dari kegagalan-kegagalan pada komponen suatu sistem. Penggunaan FMEA pada pemilihan prioritas perawatan sistem pelumasan mesin induk KM Mabrur telah dilakukan. Hasilnya berdasarkan analisa ambang batas RPN dan diagram pareto komponen saringan oli (RPN 288) dan oil cooler (RPN 120) perlu dilakukan tindakan perawatan. Berdasarkan kriteria RPN, komponen saringan oli dilakukan perawatan preventif dan oil cooler dilakukan perawatan korektif. Tindakan perawatan yang terjadwal dilakukan guna meningkatkan keandalan dari komponen sistem pelumas mesin induk KM Mabrur

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.

Abstract

The production of complex machine components requires advanced and accurate techniques. Achieving optimal quality through 3D printing involves carefully examining the process parameters. However, many studies have not thoroughly explored the impact of these parameters on parts produced using Fused Deposition Modeling (FDM) 3D printing. This study evaluates how process parameters and material variations affect the dimensional accuracy of printed parts. The study focuses on input variables such as material type, infill density, infill pattern, and raster angle. Using the fractional L9 Taguchi method, the optimal settings identified were PLA+ material, 80% infill density, an infill grid pattern, and a 0° raster angle, resulting in a 1.39%-dimensional deviation and an S/N ratio of -3.29 dB. ANOVA analysis reveals material type as the most significant factor, contributing 49.81% to performance. These findings, complemented by statistical analyses, can guide decision-making in industrial applications and serve as a reference for selecting FDM 3D printing settings related to dimensional accuracy to print components in the industry.
