Abstract

Outrigger boats are prevalent in Indonesian waters. In Indonesia, the majority of Outrigger boats have a gross tonnage of less than 7 GT, resulting in their classification as "boats." After being hit by waves, the outrigger serves as a balancing mechanism on the boat, ensuring that it does not capsize and that it continues to keep its stability. In spite of the fact that they have a number of benefits, outrigger boats also have a number of drawbacks. One of these drawbacks is that they need a mooring space that is sufficiently large to anchor the boat at the beach or pier. This research was carried out through the use of experimental methodologies. The stability value is a reference to the design parameters established by IMO A.749 (18), which are applicable to all boats. Type 2 boats have a maximum GZ value that is greater than that of type 1 boats. According to the findings of the study, the utilization of the Palabuhanratu pool was increased by 33% on model B boats and by 52% on boat C when the outrigger boom was pulled while the boat was in the port pool. This was in comparison to the original value when the boat was anchored without pulling the outrigger boom.

Abstract

Coastal communities increasingly require accessible renewable-energy education, yet conventional vocational programs rarely integrate local maritime knowledge or hands-on, culturally relevant practices. This study aims to develop and evaluate an ethnoscience-based vocational learning model that uses a simple wave-energy converter as a contextual tool. A qualitatively driven mixed-methods design was employed involving fishers, vocational students, teachers, and local stakeholders through interviews, focus group discussions, observations, and classroom implementations. Findings show that the model effectively bridges indigenous maritime knowledge with renewable-energy engineering concepts, producing pedagogically meaningful outcomes: a 21% increase in students’ conceptual understanding and a 139–270% improvement in psychomotor skills related to device design, measurement, and troubleshooting. Teachers reported enhanced capacity in contextual and multimodal instructional design, while community members recognized the model’s relevance to local energy needs. The study demonstrates that culturally grounded, low-cost engineering activities can strengthen STEM learning in resource-constrained coastal settings. These results have implications for integrating ethnoscience into vocational curricula, supporting equitable education, preserving local knowledge, and accelerating the adoption of community-based renewable technologies. This model offers a measurable pathway for policy development in vocational education, energy transition, and fisheries.

Abstract

Sea cucumbers are high value fishery commodities that play an important role in international trade. Despite their significant economic contribution, scientific information regarding the technical aspects of sea cucumber harvesting and onboard processing remains limited. This study aims to examine the technical practices of sea cucumber harvesting and onboard processing through a case study in the West Coast waters of Sumatra. The research was conducted in October 2025 in the waters of Tello Island, South Nias, using direct observation methods by participating in the entire operational sequence of sea cucumber harvesting and processing onboard fishing vessels. Primary data were collected through field observations and interviews with the vessel captain and crew members, while secondary data were obtained from fishing operation documents. The results indicate that the operational workflow of sea cucumber harvesting is systematically organized, encompassing preparation stages, compressor-assisted diving operations, and the regulation of divers’ working and resting periods. Onboard sea cucumber processing involves sequential stages of cleaning, boiling, soaking in saline solution, smoking, and drying, utilizing simple facilities and traditional methods. The technical workflows of harvesting and processing, as presented in tabular form, represent actual operational conditions in the field and provide an essential basis for understanding operational effectiveness, existing limitations, and the potential for sustainable development of sea cucumber fisheries. Key words: compressor diving, harvesting techniques, onboard processing techniques, sea cucumber

Abstract

Shark product traceability is a critical component in supporting sustainable shark fisheries management, particularly to prevent unreported, underreported, or misreported fishing practices. This study analyzes shark landing recording practices at the Nizam Zachman Ocean Fishing Port (PPS Nizam Zachman), Jakarta, one of Indonesia’s main fisheries landing ports. The research was conducted through two weeks of field observations and in-depth interviews with data enumerators, port officers, and fisheries stakeholders. The results indicate that shark landing records still rely on general fish landing standard operating procedures and lack specific guidelines for sharks, particularly for species-level identification and recording of physical condition. Sharks were frequently landed as juveniles, in non-intact conditions, and mixed with other fish species, complicating identification and increasing the risk of data inaccuracy. These conditions may undermine shark product traceability systems and sustainable shark resource management. This study recommends the development of shark-specific landing recording SOPs, capacity building for enumerators through species identification training, and the provision of visual documentation tools to improve data accuracy at landing sites. Key words: shark landing records; shark traceability; unreported fishing

Abstract

Fiber Reinforced Plastic (FRP) material has been widely used as a ship construction alternative to wood. FRP has many advantages such as lightweight material, easy maintenance, weather resistance, economical price, and shorter production time. FRP ship production is weak from the waste factor produced, such as production residue during shipbuilding, ship molds, and FRP shipwrecks. FRP waste can impact the environment, economy, and human health. These impacts include soil pollution, microplastics, skin diseases, and human respiratory disorders. FRP material tends to be burned by many shipyards but still leaves waste in the form of dust. FRP material is difficult to decompose and takes a long time to melt. One strategic effort to minimize the impact of FRP is to recycle FRP. This study aims to reduce FRP waste by making composite boards from FRP waste. The method used was experimental, involving the making of 12 specimens and testing the density, MOR, and MOE. Based on the results of the density value test, the average value obtained follows the JIS A 5905-2003 reference. The MOR and MOE values for each specimen do not comply with the Indonesian Classification Bureau (BKI) standards. In the ANOVA test calculation, no significant differences were obtained for MOR and MOE.
