Abstract

Rajungan merupakan salah satu sumberdaya perikanan yang memiliki nilai ekonomi tinggi dalam perdagangan internasional. Rajungan (Portunus pelagicus) merupakan komoditas unggulan Kabupaten Karawang. Bubu lipat sangat populer digunakan oleh nelayan dan dioperasikan dengan sistem longline sehingga memerlukan alat bantu penarik untuk mempermudah dan mempercepat dalam operasi penangkapan. Informasi karakteristik teknis alat bantu penangkapannya masih sangat minim oleh karena itu perlu dilakukan kajian lebih lanjut. Penelitian ini bertujuan untuk menganalisa karakteristik teknis alat bantu penarik bubu rajungan terutama terkait desain, kebisingan dan konsumsi bahan bakar. Karakteristik teknis alat bantu penarik bubu rajungan dideskripsikan sesuai kondisi saat ini, sedangkan untuk kebisingan dan konsumsi bahan bakar dilakukan analisis deskripsi komparatif. Alat bantu penarik bubu pada nelayan pesisir Karawang terdapat perbedaan pada pereduksi putaran (gear box). Tenaga penggerak menggunakan mesin diesel dengan daya 8 – 12 PK, roda piringan penarik (line spool plate) terbuat dari bahan besi plat dan kayu serta karet ban bekas sebagai pelapis dengan diameter 17 – 50 cm. Gear box menggunakan gardan bekas dan roda gigi cacing (worm gear set). Kebisingan yang dihasilkan mesin penggerak pada area nelayan bekerja melebihi nilai ambang batas yang ditetapkan yaitu 91 dB dengan lama paparan lebih dari 2 jam. Dalam jangka panjang hal ini dapat menyebabkan gangguan pendengaran yaitu ketulian. Besaran nilai konsumsi bahan bakar mesin penggerak alat bantu dengan daya 8 dan 12 PK mesin penggerak pabrikan Jepang lebih unggul. Konsumsi bahan bakar pada kondisi putaran minimum dan maksimum untuk mesin berdaya 8 PK adalah 1,48 dan 5,93 liter, sedangkan mesin berdaya 12 PK adalah 2,35 dan 10,35 liter.Blue swimming crab (Portunus pelagicus) is a fishery resource that has the potential to utilize because it has high economic value in international trade. Portunus pelagicus is a leading export fisheries commodity in Karawang Regency; collapsible pots are very popular fishing gear fishermen use. The fishing is operated with a longline system that requires auxiliary hauling equipment to simplify and speed up the fishing operation. Information on auxiliary fishing equipment's technical characteristics is still minimal; therefore, further studies are needed. This study analyzes the pot hauler's technical characteristics, especially regarding design, noise, and fuel consumption. The technical characteristics of the pot hauler are described following the existing conditions, while a comparative descriptive analysis was carried out for noise and fuel consumption. There are differences in the gearbox for the fishing traps for fishermen in the coastal area of Karawang. The driving force uses a diesel engine with a power of 8-12 HP, the towing wheel (line spool plate) is made of iron plate and wood, and used rubber tires as a coating with a diameter of 17-50 cm. The gearbox uses a used axle and a worm gear set. The noise generated by the auxiliary equipment engines in the fishermen's working area exceeds the set noise limit value of 91 dB with an exposure period of more than 2 hours. In the long term, this could cause deafness to the fishermen. Theoretically, the fuel consumption value of the auxiliary equipment engines, with a power of 8 and 12 HP of the Japanese manufacturer, is superior. The fuel consumption at the minimum and maximum rotation conditions for the 8 HP engine is 1.48 and 5.93 liters, while the 12 HP engine is 2.35 and 10.35 liters, respectively.

Abstract

Material innovation in the manufacturing and automotive industries plays an important role in improving engine performance and durability. Conventional materials such as steel and aluminum have limitations in resistance to extreme temperatures and wear, so new materials such as high-performance metal alloys, carbon fiber composites, and nanotechnology-based materials are developed as solutions. These materials are capable of improving energy efficiency, reducing weight, and extending component life. However, the adoption of new materials faces challenges such as high production costs, fabrication complexity, and validation in real operational environments. Therefore, collaboration between academia, industry and government is needed to develop solutions that are not only technically superior, but also economical and sustainable. This research uses the SWOT method to analyze the strengths, weaknesses, opportunities, and threats in the application of new materials. Data were obtained through literature studies, laboratory experiments, and expert interviews. The analysis results show that materials such as carbon fiber composites (CFRP) have advantages in fuel efficiency and corrosion resistance, but also face challenges in production and maintenance costs. With innovations in manufacturing technology and a more sustainable approach, new materials have the potential to be the optimal solution for the automotive and manufacturing industries in the future

Abstract

Renewable energy planning is a complex process, involving multiple dimensions, including natural resource availability, government policies, and socio-economic factors. This study emphasizes the importance of a decision-making approach that is not only technically based, but also considers the social and political factors that influence policy implementation. Decision-making in renewable energy planning is often hampered by information inequality between stakeholders, social resistance, and policy instability that can slow down a sustainable energy transition. Multi-Criteria Decision Making (MCDM) methods have been used to help stakeholders choose the best option, but overly technical approaches can be a barrier in developing countries. Therefore, simpler and more data-driven approaches, such as heuristic models, become more relevant in contexts of uncertainty. This research uses a descriptive qualitative approach through case studies to explore the dynamics of decision-making in renewable energy planning. Data were collected through in-depth interviews, focus group discussions (FGDs), and document analysis. The results show that transparency, open communication and stakeholder participation are essential to overcome social and political barriers and support effective and sustainable renewable energy policy implementation.

Abstract

The tuna handlines operated by some fishers from Southern Malang in the Indian Ocean can be categorized as a type of static fishing gear. The stability of their small-sized vessels becomes critical when a large-sized tuna is caught by the handline and lifted with the help of a line hauler installed onboard, i.e., the floating angle tolerance may be exceeded.   This study aims to determine the angle of inclination of a 9 GT boat when a line hauler is operated onboard.  The research was carried out in June 2016 by measuring the principal dimensions of a fishing boat, FV Cahaya 01, in Pondok Dadap Fishing Port, Malang.  The principal dimensions are length overall (LOA), length before perpendicular (LPP), breadth (B), and depth (D) Data on the boat's principal dimensions, lines plan, and hull shape were used for the boat’s stability calculation.   The studied boat's buoyancy center is located at 0.27 m in front of the midship and the TCP is 0.315. The maximum load of the line hauler was 211.253 kg, and the inclination angle during the hauling process was 3.520.  The installation of the line hauler on the fishing boat creates a new acceptable stability of the boat.

Abstract

This study discusses the paradigm shift in mechanical engineering due to the adoption of 3D printing technology as part of the industrial revolution 4.0. This additive manufacturing technology offers advantages in terms of design complexity, production efficiency, and cost flexibility, but also raises technical challenges such as material anisotropy, surface roughness, and process parameter control. Through a descriptive qualitative approach based on literature studies, this study explores the impact of 3D printing on the structure of the manufacturing industry, performance-based design, and the need for reform in engineering education. Data sources are taken from scientific journals, academic books, and technical reports from the last decade (2014–2024), with a thematic analysis of technology applications, implementation challenges, and implications for mechanical engineering curricula. The results show that although 3D printing has fundamentally changed the design and production process, its integration into the industry is still limited by conventional supply chain structures and lack of human resource readiness. This study emphasizes the importance of transforming the engineering education system towards a digital-based interdisciplinary approach, as well as the need for critical and contextual technology adoption. Thus, 3D printing does not only act as a production tool, but also as a catalyst for systemic change in mechanical engineering and manufacturing.
