This study aims to analyze the effect of combining bait types and immersion durations on the catch yields of blue swimming crabs (Portunus pelagicus) in the waters of Kuala Penet, East Lampung. The research method employed was a field experiment utilizing a factorial Completely Randomized Design (CRD). The focus of the study was directed toward two types of bait, namely goldstripe sardine (Sardinella spp.) and chicken intestines, with three variations of immersion duration: 6 hours, 12 hours, 18 hours, and 24 hours. Through statistical analysis, it was discovered that the combination of goldstripe sardine bait and a 6-hour immersion duration provided the most optimal catch yields. Nevertheless, chicken intestines demonstrated strong potential as an economical and sustainable alternative bait at a 12-hour immersion duration. The interaction between the bait type and immersion duration variables proved to be significant, thereby supporting an integrated approach to the management of collapsible pots. These findings provide a scientific basis for formulating sustainable crab fishing guidelines that can be adopted by local fishermen and relevant authorities to support the ecosystem-based conservation of coastal fishery resources in East Lampung.

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.

Agrarian conflict is a common issue in development processes, particularly when changes in land ownership or control involve various interests. This study aims to analyze the dynamics of agrarian conflict in the coastal area of ​​Atapupu Beach, Jenilu Village, Kakuluk Mesak District, Belu Regency, triggered by the land acquisition process by the Defense University (UNHAN). The study used a qualitative approach with a case study method to understand the social conditions developing in the community. Data were obtained through in-depth interviews, field observations, and documentation. The results indicate that the conflict arose due to changes in community access to coastal areas previously used for economic activity. The presence of UNHAN has restricted community activities in the Fish Auction Place (TPI) area, previously a center for fishing activities. This situation has given rise to social tensions between the community and the area management. This study emphasizes that coastal area management needs to consider local community interests through a dialogical and participatory approach to minimize agrarian conflict.

The forms of local wisdom of the Bajo Tribe that play a role in preserving the environment are: The Bajo Tribe's belief in spirit spirits or the supernatural, the Tibaanca tradition, and the use of traditional fishing gear. Local wisdom has a role in preserving the environment such as: Sustainable use of natural resources, protection of biodiversity, and control of environmental pollution. The Bajo tribe in Torosiaje uses local wisdom that they hold fast to to preserve the environment from environmental damage.

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.

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 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 purpose of this study is to determine the effectiveness of using light sticks and without lights on catching ribbonfish from the number of catches. The method used in this study is an experimental fishing method with data analysis using the T test. This study was conducted in the waters of Pasongsongan Sumenep. The results of the ribbonfish catch during 16 trips with light sticks totaled 163 fish, while those without lights totaled 67 fish. The type of ribbonfish caught was dominated by the Trichiurus lepturus species. From the catch results, a T test analysis was carried out and the results of the Paired samples test showed a sig. value (2-tailed) of 0.000 <0.05, which means there is a significant difference in the number of catches in the use of light sticks and without lights placed on the fishing hook position. This is because ribbonfish have phototactic properties towards light, in addition to searching for food more dominantly using the sense of sight.

The fishing gear operated by fishermen along the coast of Grajagan Beach to catch fish is a bottom gill net, using different mesh sizes of 3, 4, and 6 inches. The method used in this study was the Experimental Fishing method, which involved direct observation over nine repetitions using different mesh sizes. Observations were conducted on the quantity of fish caught, and direct interviews were carried out with fishermen regarding the use of gill nets at Grajagan Beach, Banyuwangi, East Java. The composition of the catch showed that the largest proportion by weight was shovel-nosed ray, accounting for 15%, while lobster represented the highest number of individuals caught, at 12%. To determine whether there was an effect of mesh size on the catch yield, an ANOVA test was conducted and produced significant results, indicating that differences in mesh size significantly influenced the catch. In this study, a follow-up (Post Hoc) test was also performed using Tukey’s Honest Significant Difference (HSD) test. The results of the post hoc test showed that the use of a 6-inch mesh size had a substantial effect on the catch yield.

Long fishing is an environmentally friendly traditional fishing tool that is commonly used by fishermen to catch fish passively using bait, both in sandy waters and in coral reef areas. Grouper fish (Epinephelus sp.) tend to inhabit waters of a certain depth, especially in areas of coral fractures and dead corals that serve as shelter and foraging. Determining the right depth setting in the operation of a fishing rod is essential to optimize the catch. This study aims to determine the effect of the difference in setting depth on grouper fish catch in the waters of Pengambengan Beach and determine the most effective depth. The study used an experimental method with three depth treatments, namely 10 m, 15 m, and 20 m, each repeated nine times. Data analysis was carried out by Group Random Design (RAK) and ANOVA test. The results showed that a depth of 10 m produced the highest catch with a total of 35 fish (average 3.89 fish/trip), followed by a depth of 15 m with 10 fish (average 1.11 fish/trip), and a depth of 20 m with 7 fish (average 0.78 fish/trip). Statistically, the difference in depth has a real influence on the number of grouper catches. A depth of 10 m is recommended as the optimal setting for the operation of long fishing rods in the waters of Pengambengan Beach.

Swanggi fish (Prianchantus tayenus) is one of the important commodities that are widely caught at the Perikanan Nusantara Port (PPN) Brondong, Lamongan, East Java. Increased fishing acivity is feared to cause excessive pressure on fishery resources that could potentially cause overfishing. This study aims to analyze the level and status of swanggi fish utilization. The method used in this research is descriptive quantitative with a fox production surplus model approach to calculate Maximum Sustainable Yield (MSY), Totl Allowable Catch (TAC), and utilization rate. The data analyzed were the catch abd effort of swanggi fishing from 2015 to 2024. The result showed that the Maximum Sustainable Yield (MSY) value of Swanggi fish was 14,486,042 kg/year with an optimum effort F MSY of 11,689 trips/catch and TAC of 11,588,833 kg. the utilization rate of swanggi fish during 2015 to 2024 reached 105%. The value of the utilization status of swanggi fish is 85% which can be categorized that the exploitation of swanggi fish resources is Full Exploited. Therefore, sustainable fisheries management is needed through effort limitation and gear evaluation to maintain the sustainability of swanggi fish resources in PPN Brondong.

Industrial development in coastal areas through the construction of a Steam Power Plant (PLTU) has significant economic implications for the sustainability of fishermen's livelihoods. This study aims to analyze the impact of PLTU operations on the socio-economic conditions of fishermen in Teluk Sepang Village, Bengkulu City. This study used a qualitative descriptive approach with a snowball sampling technique, involving 26 small-scale and traditional fishermen directly affected. The results indicate that damage to the coastal ecosystem due to PLTU activities reduces water quality and the availability of fish resources, resulting in decreased catches and income instability. Fishermen are forced to venture farther out to sea, incurring increased operational costs, further putting pressure on household economic conditions. This economic pressure exacerbates fishermen's vulnerability due to limited capital and high dependence on marine resources. Fishermen's adaptation strategy involves diversifying their livelihoods into non-fishing sectors, such as laboring to supplement household income. Changes in social conditions are reflected in the decline in fishermen's solidarity, marked by a weakening of mutual cooperation (gotong royong) and a reduction in collective cooperation due to economic pressures. This study demonstrates that PLTU operations impact the socio-economic structure of fishermen, necessitating sustainable protection and empowerment policies for coastal communities.

This community service program aims to strengthen legal awareness among Kodingareng fishers through community-based legal education tailored to their social characteristics and work structures. The program was implemented through initial mapping, participant segmentation based on local fishing typologies—papekang, papattek, and pagae—and dialogical legal education linked directly to everyday fishing practices. The educational content focused on clarifying categories of prohibited acts, legal consequences, and individual responsibility within both independent fishing and vessel-based collective work. The results indicate an improvement in participants’ ability to articulate legal boundaries, assess legal risks based on specific actions, and understand the relationship between legal compliance, resource sustainability, and household livelihood stability. Although economic pressure, long working hours, and patron–client relations remain significant constraints on rapid behavioral change, the enhancement of legal awareness represents a meaningful outcome within the framework of community service. The findings suggest that community-based legal education can function as an effective preventive strategy against fishing-related crimes and provide a foundation for sustained legal empowerment initiatives in small island communities.

Infrastructure expansion has been increasingly recognized as a transformative force shaping the social, economic, and cultural dynamics of coastal communities. This study investigates the effects of major infrastructure development specifically ports and toll roads on social mobility and religious practices within the traditional fishing communities of Bengkalis Island. Using a qualitative design, data were collected through field observations, in-depth interviews with fisherfolk, local leaders, and religious figures, as well as reviews of regional development policies. The findings reveal that new infrastructure has introduced shifts in livelihood patterns, encouraging economic diversification beyond traditional fishing activities. These shifts contribute to both upward and horizontal mobility, altering long-standing social hierarchies within the community. Moreover, the changing economic landscape influences religious life: traditional maritime rituals experience reduced centrality, while formalized religious organizations gain greater authority and participation. Infrastructure development also increases exposure to external cultural influences, accelerating negotiations of religious identity and modern interpretations of faith. Overall, this study argues that infrastructure projects function not only as physical catalysts of development but also as sociocultural drivers that reshape belief systems, communal relations, and the lived realities of traditional fishing populations. The research highlights the necessity of adopting development strategies sensitive to local contexts and cultural continuity.

This research analyzes the Indonesian government’s policy responses to combating Illegal, Unreported, and Unregulated (IUU) Fishing in the Arafura Sea during 2023-2024, focusing on the case of the Run Zeng 03 and Run Zeng 05 vessels. These foreign-flagged vessels, owned by a Chinese company but registered under the Russian flag, were involved in illegal fishing and human rights violations against Indonesian fishery crew members. Using a qualitative descriptive approach supported by literature studies and official government data, this research analyzes how Indonesia implemented its maritime sovereignty through legal enforcement, inter-agency coordination, and international maritime diplomacy. The findings reveal that Indonesia’s measures, such as vessel monitoring AIS/VMS technology, law enforcement through arrests and seizures, and diplomatic engagement with flag states reflect a progressive but still reactive approach. The study identifies key challenges, including limited foreign authorities. This research highlights the need for an integrated policy framework that combines hard power (law enforcement and patrols) with soft power (international cooperation, economic diplomacy, and labor protection). The study concludes that a comprehensive and collaborative approach is essential to strengthen maritime governance and ensure sustainable, equitable management of Indonesia’s marine resources.
