Many fishery products come from fishing and cultivation, saltwater and freshwater fisheries, so a preservation process is needed to maintain the condition of the fish so that it remains good when marketed. In addition, it can increase the economic value of fish. In the Indonesian fisheries industry, various types of preservation, including freeze drying, are drying processes using vacuum pressure and cold temperatures. The freeze-drying process utilizes the phased nature of water to convert solid (frozen) forms into water vapor (gas) at a certain pressure and temperature. The vacuum pressure used ranges from -60.3 cmHg to -71.6 cmHg, and the mass of the fish ranges from 94 grams to 136 grams. The type of research is quantitative and uses experimental methods. The result is in the form of a remaining moisture content percentage of 40% in dried fish according to SNI standard No. 827300:2023. The Respone Surface Methodology (RSM) was used to process the data in this study. From the study, the best value of vacuum pressure was -66 cmHg and mass 102.5417 with a final result of 40%.

The sea fence in Tangerang Regency, Banten, has become a complex issue involving violations of spatial law, environmental impacts, and the rights of coastal communities. This research analyzes the social and environmental impacts of the case and examines the protection and restoration of victims' rights based on a greenvictimology perspective. Using an empirical juridical approach, data collection was conducted through interviews with fishermen and legal aid organizations, as well as secondary data from legal literature. The results showed that sea fences disrupt fishermen's activities, damage marine ecosystems, and violate regional spatial regulations. Ecological impacts include changes in ocean currents, decreased water quality, disruption of fish migration, damage to coral reefs, and coastal abrasion. Protection and restoration of victims' rights in the Pagar Laut case to date have not been fully fulfilled and realized by the responsible parties. This can be seen from the absence of concrete policies and concrete actions in the form of providing compensation or compensation to fishermen who are directly affected by the installation of the Sea Fence which hampers their access and space for fishing activities. In addition, efforts to restore the marine environment have also not been carried out optimally, especially in terms of dismantling sea fences that have not been carried out thoroughly and assistance programs from the Ministry of Maritime Affairs and Fisheries have not been implemented.

This study aims to obtain an overview of Human Resource Management (HRM) practices at the Fisheries Service of Gorontalo Regency. A descriptive qualitative approach was used in this study, with data collection techniques through interviews, observations, and documentation. The results of the study indicate that planning is carried out through a recruitment process that includes identifying needs, preparing job descriptions, and the orientation process for new employees. In terms of organization, service digitalization is applied to accelerate administration, increasing HR capacity through training, and involving the community in fisheries policies, which have been proven to increase service efficiency by up to 80%. However, implementation has not been optimal due to limited time, resources, communication constraints, and budget constraints. Work supervision involves leaders, supervisory positions, and other relevant parties, with leaders playing a central role in ensuring employee performance. Motivation is provided by providing opportunities for skill development and rewards for performance. Performance evaluations are carried out periodically to measure the achievement of organizational targets and goals. These findings provide important insights into efforts to improve the quality of human resource management in the public service sector.

Illegal fishing is a form of maritime crime that threatens the sustainability of marine resources and causes significant economic losses for the country, particularly for coastal communities such as those in Natuna Regency. This activity not only harms the fisheries sector but also impacts food security, social stability, and the marine ecosystem. This study aims to examine in depth the surveillance strategy implemented by the Maritime Security Agency (Bakamla) in combating illegal fishing practices in Natuna waters. The research method used is a qualitative descriptive approach with data collection through in-depth interviews and analysis of Bakamla's strategic documents. The theoretical framework used refers to the concept of strategy according to Fred R. David (2016), which includes strategy formulation, implementation, and evaluation. The results of the study indicate that Bakamla has formulated a surveillance strategy by relying on 24-hour sea patrols, utilizing technologies such as the Automatic Identification Sistem (AIS), radio communications, and satellites, and establishing cross-agency collaboration including the Indonesian Navy, the Ministry of Maritime Affairs and Fisheries, and local government officials. The strategy was implemented through rotating patrols, outreach activities for fishermen and coastal communities, and the establishment of a public reporting channel to facilitate the dissemination of information regarding illegal activities. However, the implementation of this strategy still faces obstacles, including limited operational budgets, inadequate patrol fleets, and suboptimal response to public reports. Evaluation of the monitoring strategy showed positive impacts in the form of increased public awareness and participation, as well as a decrease in cases of fish theft in several vulnerable areas. However, the level of public involvement in reporting and independent monitoring still needs to be increased so that the monitoring strategy can be more effective and sustainable in safeguarding the sovereignty of Indonesia's marine resources.

Fisheries extension services play a strategic role in strengthening the capacity of fish farmers and accelerating the development of sustainable aquaculture businesses. The effectiveness of extension activities is strongly influenced by how fish farmers perceive the roles performed by fisheries extension workers. This study aims to analyze the level of fish farmers’ perceptions of the role of fisheries extension workers in developing aquaculture businesses in Loa Kulu District, Kutai Kartanegara Regency. In addition, this research examines the characteristics of fish farmers and analyzes the relationship between internal and external factors and the level of perception toward extension roles. This study employed a descriptive and correlational research design using both qualitative and quantitative approaches. A total of 42 respondents were selected from 719 fish farmers using the Slovin formula with a 15% margin of error and proportionate stratified random sampling across 10 villages. Data were collected through structured questionnaires using a Likert scale and analyzed using descriptive statistics and Spearman's rank correlation analysis. The results indicate that the overall perception of fish farmers toward the roles of fisheries extension workers—namely as educators, facilitators, motivators, innovators, advocates, organizers, and evaluators—falls within the high category. Among these roles, the organizer and facilitator roles received the highest perception scores. Internal factors such as age, income, and land area showed significant correlations with certain extension roles, particularly the roles of educator, motivator, and evaluator. External factors, including interaction with extension workers, interaction with traders, availability of market information, and access to aquaculture science and technology, were also significantly correlated with perception levels. These findings suggest that strengthening both socio-economic conditions and access to information and technology can enhance positive perceptions of extension services, ultimately contributing to more effective aquaculture development programs. The study highlights the importance of optimizing extension performance to sustain fish farmers’ productivity and welfare improvement.

Post-harvest handling of fish requires an effective cold chain system, including the availability of ice factories, to preserve the quality and freshness of catches. The presence of an ice factory enables fishermen to bring ice during fishing trips, ensuring the catch remains safe for consumption. The planning of a portable mini ice factory in Ciwaru Village, located within the Ciletuh National Geopark, aims to maintain fish quality along the southern coast of West Java. Although several ice factories exist in Sukabumi Regency, their availability at fish landing sites such as the Ciwaru Fish Auction Place (TPI) remains insufficient. According to the Regulation of the Minister of Marine Affairs and Fisheries No. 2 of 2021, assistance for ice factory construction is provided to fishermen groups following a feasibility study submission. This community service project aims to assist fishermen cooperatives in improving cold chain management and preparing a feasibility study for ice factory development. Key issues identified include limited human resource competence, hygiene and sanitation challenges, feasibility study preparation, and internal communication enhancement within cooperatives. Solutions are implemented through training programs, cold chain method applications, feasibility analysis for mini ice factories, and the development of an information system for fishermen. The planned ice factory unit has a capacity of 1 ton per 8-hour cycle, supported by three freshwater wells near the site. Economic analysis reveals an NPV of Rp1,170,676,141, an IRR of 10.91%, and a Net B/C Ratio of 1.64, with a BEP at 311 tons/year, well below the installed capacity of 788 tons/year, confirming its economic viability. The resulting feasibility study will serve as the basis for applying for government assistance, complemented by scientific publications, national media coverage, video documentation, and intellectual property registration.

Tuna fisheries are a strategic sector in Indonesia's fishing industry, contributing significantly to the national economy. Albacore tuna (Thunnus alalunga) has high economic value and is one of the main commodities in international trade. This study aims to analyze the effect of different longline setting times on albacore tuna catches in the Seas of Benoa Harbor. The setting times compared were morning (08:00–10:00) and afternoon (14:00–16:00), focusing on the quantity and weight of the catch. The research method used was an experimental approach with two setting time treatments and nine replications for each treatment. Data obtained were analyzed using a T-test to determine significant differences between morning and afternoon catches. The results showed that the average catch in the morning was higher than in the afternoon, both in terms of individual count and fish weight. The average fish weight obtained in the morning was 63.78 kg, while in the afternoon, it was only 28.67 kg. Statistical analysis indicated a significant difference between morning and afternoon catches, with a T-Statistic value of 2.38, which exceeded the T-Critical value (2.12) at a 5% significance level (p-value = 0.0366). This suggests that the morning setting time is more optimal for catching albacore tuna than the afternoon setting. Catch variation was also greater in the morning, as indicated by a higher standard deviation compared to the afternoon. This difference may be attributed to the daily migration patterns of albacore tuna, which are more active in feeding during the morning, as well as environmental factors such as water temperature and light intensity. Based on these findings, this study recommends that fishers in the Seas of Benoa Harbor should set their longline fishing gear in the morning to maximize their catch.
