Gorontalo Province has abundant freshwater resources, yet lacks integrated and sustainable aquaculture facilities. This article presents the conceptual design of a Freshwater Fish Aquaculture Center in Gorontalo Province as a response to this condition, applying Ecological Architecture as the primary design approach. The designed area accommodates various activities including freshwater fish cultivation, education, tourism, as well as research and development of fisheries technology. The method used is a qualitative descriptive approach through literature studies, field observations, interviews, and precedent studies. The design results show that the area can be divided into four main zones: the aquaculture zone, education zone, tourism zone, and supporting zone. The ecological approach is realized through the use of natural lighting and ventilation, environmentally friendly materials, an integrated water management system, and the maximization of green open spaces. This design is expected to increase fisheries productivity while promoting community empowerment through educational activities and environmentally sustainable tourism.

The fisheries sector plays an important role in Indonesia’s economy due to its abundant marine resources; however, unsustainable fishing activities have caused damage to marine ecosystems and a decline in biodiversity. To support sustainable fisheries management, the use of environmentally friendly fishing gear is essential. At the Tenau Coastal Fishing Port (PPP Tenau) in Kupang, East Nusa Tenggara, handline fishing is the most commonly used traditional fishing method among small-scale fishers because it is selective and causes minimal habitat disturbance. This study aims to analyze the environmental friendliness level of handline fishing gear based on the nine criteria of the Code of Conduct for Responsible Fisheries (CCRF) established by FAO in 1995, which include gear selectivity, habitat impact, fisher safety, catch quality, product safety, by- catch, biodiversity impact, capture of protected species, and social acceptance. The research was conducted from November 2025 to January 2026 using a descriptive quantitative method involving 30 handline fishermen selected from a population of 420 using the Slovin formula with a 20% error rate. Data were collected through observation, interviews, and documentation, then analyzed using a weighting system based on the guidelines of the Ministry of Marine Affairs and Fisheries (2006). The results are expected to show that handline fishing is categorized as environmentally friendly to highly environmentally friendly and can serve as a basis for developing sustainable fisheries management policies in East Nusa Tenggara.

Gillnet fisheries play an important role in supporting the local economy and the welfare of coastal communities. However, fishermen still face challenges related to unequal access to livelihood assets and high vulnerability to external factors such as seasonal changes, catch fluctuations, market pressures, and environmental conditions. This study aimed to analyze the level of vulnerability, identify livelihood assets, and formulate strategies for sustainable livelihood development among gillnet fishing communities. The study was conducted in Margasari and Muara Gading Mas Villages in September 2025 using a mixed-method approach, combining questionnaires, in-depth interviews, and field observations. Samples were selected through purposive sampling, and data were analyzed using descriptive quantitative and qualitative methods supported by a Likert scale. The results showed that fishermen’s vulnerability is relatively high (54.5%), affecting income stability. Social (81.4%) and natural (78.7%) assets are relatively strong, while human (38.6%), physic (48.3%), and financial (43.20%) assets remain relatively low. Limited education, lack of training, and restricted access to financial resources are the main constraints, leading to low adaptive capacity and limited livelihood diversification. Recommended strategies include improving human resource capacity, strengthening access to financial capital, and developing livelihood diversification based on local potential. These efforts are expected to enhance household economic resilience and support sustainable livelihoods among gillnet fishing communities.

This study aims to analyze the level of environmental friendliness of gillnet fishing gear operated by fishermen in Pangandaran Regency. Sustainable management of fishery resources is crucial in this region, given the high biodiversity and the pressure from environmentally damaging fishing activities. The methods used in this study include field observations, interviews, and the distribution of questionnaires to 30 respondents. Data analysis was conducted by scoring based on the nine criteria for environmentally friendly fishing gear established by the FAO Code of Conduct for Responsible Fisheries (CCRF) 1995. These nine criteria include gear selectivity, impact on habitat, fisherman safety, catch quality, consumer safety, impact on biodiversity, protection of endangered species, and social acceptance. The results showed that gillnet fishing gear in Pangandaran Regency obtained an average score of 28.3. Based on the CCRF assessment categories, this value places gillnets in the environmentally friendly category. Nevertheless, the selectivity aspect remains the lowest-scoring factor as the gear still catches more than three species with varying sizes. On the other hand, this fishing gear proved to be safe for habitats, poses no danger to fishermen, produces safe products for consumers, and is well-received socially by the local community.

The environmental friendliness of a fishing gear is an important component in sustainable fisheries management. The use of environmentally friendly fishing gear that complies with the Code of Conduct for Responsible Fisheries is absolutely necessary. Environmental friendliness refers to the ability of a fishing gear to catch fish with minimal environmental impact, because even though the fishing gear can catch fish well, the fishing gear can still cause problems with the marine environment, such as damage to coral reefs and non-selective fishing. The purse seine fishing gear used by fishermen in Laha Village, Ambon is one of the effective fishing gears in catching various types of pelagic fish such as scad, tuna, lemuru, skipjack and mackerel. Purse Seine fishing gear also has a negative impact on the marine ecosystem and therefore this study was conducted to determine the environmental friendliness of Purse Seine fishing gear. The research method that will be used is a descriptive method, namely interviews using questionnaires given to fishermen and data collection through field observations. Based on the results of the study, the Purse Seine fishing gear in Laha Village, Ambon is used to catch several types of small and large pelagic fish and the main catch is scad and skipjack tuna. Based on the calculation results of the criteria for environmentally friendly fishing gear, a score of 30 was obtained, so it can be concluded that the Purse Seine fishing gear in Laha Village, Ambon is included in the very environmentally friendly category. It is recommended that fishermen in Laha Village prioritize their safety and security during the fishing process and while sailing.

This study aims to analyze the effectiveness of public service policy implementation at the Regional Technical Implementation Unit of the Freshwater Fish Cultivation Center (UPTD BBIAT) in Pekalongan Regency, focusing on the influence of service quality on fish farmers' satisfaction mediated by trust. The research employs a mixed-methods approach with a concurrent embedded design, combining a survey of 40 fish farmers and in-depth interviews with 5 key informants from the UPTD and Agency levels, along with observation and document analysis. The theoretical framework is built on New Public Service Theory, Policy Implementation Theory, and the SERVQUAL, trust, and public satisfaction concepts. The research findings indicate that all three variables are in the high category with robust and significant positive correlations: service quality with trust, service quality with satisfaction, and trust with satisfaction. Trust has been shown to play a strong mediating role in the relationship between service quality and fish farmers' satisfaction. The assurance and empathy dimensions are the strengths of UPTD BBIAT, while tangibles and reliability require improvement through infrastructure modernization and enhanced consistency in seed availability. Theoretically, this research confirms the applicability of the SERVQUAL model and trust theory in the context of public services in the fisheries sector. In practice, it provides strategic recommendations to improve policy implementation effectiveness through infrastructure strengthening, human resource development, service digitalization, and enhanced institutional coordination.

This study examines how the transition from manual to digital services influences user satisfaction through digital service quality and user perception at the Marine and Fisheries Office of Pekalongan Regency. The research employs a mixed-methods approach, combining a quantitative survey (N = 40) using Pearson correlation analysis with qualitative interviews involving service leaders and operators. The results reveal very strong correlations between service quality, user perception, and user satisfaction, as well as the critical role of system stability and operator assistance in shaping user experience. Qualitative findings confirm that changes in work culture, leadership, and human resource adaptation are key factors in the success of digitalisation. The study implies that the success of digital public services is determined not only by technology but also by strengthening human resource capacity, simplifying service design, and providing operator support for users with low digital literacy. The limitations of this study include the small sample size, the single organisational context, and reliance on perception-based data. Future research is recommended to conduct comparative cross-agency studies, longitudinal approaches, and structural model testing to examine the mediating roles of digital literacy and operator assistance.

In Indonesia, maritime safety remains a problem. Ship captains and ship owners often disregard maritime safety standards, particularly for fishing vessels. Provisions for criminal liability for domestic fishing vessels that fail to meet maritime safety standards are an important legal instrument for regulating and enforcing maritime safety regulations in the fisheries sector. Failure of vessels to comply with safety requirements, such as the completeness of safety equipment, engine condition, and vessel structure, can potentially lead to accidents that endanger the lives of crew members and negatively impact the marine environment. This study uses a normative research method with a legislative approach. This article focuses on examining aspects of criminal liability, including the subjects, objects, and legal sanctions imposed for violations of maritime safety standards. The results indicate that perpetrators of violations can be subject to criminal sanctions in the form of fines, detention, and even revocation of vessel operating permits, taking into account human rights and environmental protection. Effective and synergistic law enforcement between relevant authorities is essential to provide a deterrent effect, encourage compliance with safety standards, and improve the system for the sustainability of marine resources.

Catfish farming is one of the fisheries areas with great potential in Indonesia. However, the problem of feed efficiency, use of probiotics, and air temperature control are still the main obstacles that affect the health and growth of fish. This study aims to design and implement an automatic system that can regulate the provision of feed and probiotics and control and control air temperature directly using the ESP32 microcontroller. This system has several important components, such as the ESP32 microcontroller as a control center, servo motors for feed and probiotic distribution, and DS18B20 temperature sensors to monitor air temperature. All components can be controlled and viewed through an IoT-based application with a Wi-Fi connection or applications such as Telegram. This trial aims to determine whether this system can provide feed and probiotics according to the specified time, and maintain air temperature in the optimal range (28°C–40°C) for catfish growth. In this way, the system is expected to increase efficiency in catfish farming automatically, reduce the need for human labor, and minimize errors in pond management.

This study aimed to analyze the implementation of policies prohibiting illegal fishing practices involving the use of explosives, poisons, and electric shock devices in Sanga-Sanga District, Kutai Kartanegara Regency. Although regulations and extension activities related to the prohibition have been established, illegal fishing practices continue to occur as of 2025. The findings reveal that some fishermen still use poison and electric shock due to economic reasons and the perception that these methods yield greater catches. However, such actions cause losses to other fishermen by reducing the quality of the catch and damaging the aquatic ecosystem. The community is aware of these violations but is reluctant to report them due to fear of threats from the perpetrators. Efforts by fisheries extension officers to establish community-based surveillance groups (Pokmaswas) have not been optimal due to low public participation. Collaboration between provincial fisheries supervisors and the local marine police (Polairud) has resulted in joint patrols that successfully apprehended two perpetrators of illegal fishing, yet law enforcement has not produced a deterrent effect. Moreover, the program to replace destructive fishing gear with environmentally friendly alternatives for fishermen willing to transition has not been realized due to budget constraints. Based on these findings, it is necessary to strengthen integrated surveillance, provide legal protection for whistleblowers, accelerate the implementation of sustainable fishing gear programs, and enhance public awareness of legal and ecological issues.

This study examines the implementation of the Minister of Marine Affairs and Fisheries Regulation Number 7 of 2024 concerning the Management of Lobster, Crab, and Blue Swimming Crab in East Kalimantan. As a strategic policy, the regulation aims to ensure sustainable fisheries management through provisions on minimum catch sizes, restocking mechanisms, traceability systems, and law enforcement against illegal fishing and trade. Using an empirical juridical approach, this research collected primary data through questionnaires distributed to fisheries officers, coastal communities, fishers, and aquaculture business actors in East Kalimantan. The results show that the implementation of Regulation No. 7/2024 is generally categorized as moderately effective, with an average Likert score indicating limited but positive compliance. Respondents acknowledged the importance of sustainability principles embedded in the regulation; however, significant challenges persist, including insufficient formal socialization, weak field monitoring, lack of supporting facilities, and inconsistent coordination among implementing agencies (BARANTIN, PSDKP, and local fisheries officers). Qualitative responses highlight that many stakeholders still lack understanding of technical provisions such as minimum size requirements and restocking obligations. The study concludes that while the regulatory framework is normatively comprehensive and aligned with sustainable fisheries principles, its practical effectiveness remains constrained by institutional and socio-cultural factors. Strengthening community engagement, increasing inter-agency coordination, and enhancing enforcement capacity are crucial to optimizing the policy’s impact on the sustainable management of lobster, crab, and blue swimming crab resources in East Kalimantan.
