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.

Fishermen are an essential group in supporting national food security; however, their lives are still characterized by various social and economic challenges, such as unstable income, low education levels, and high household expenditure burdens. This research aims to provide an overview of the socio-economic conditions and welfare of Bouke Ami fishermen in the Nusantara Fisheries Port (PPN) Muara Angke, North Jakarta, through the Fishermen’s Exchange Rate (NTN) and Fishermen’s Exchange Rate Index (iNTN). The study was conducted in May–June 2025 using a descriptive method with quantitative and qualitative approaches. Data collection techniques included observation, interviews, and questionnaires distributed to 100 Bouke Ami crew members (ABK). The results showed that the majority of crew members were aged 30–39 years, had completed only junior high school education, received health services through community health centers (puskesmas), had three family dependents, and most lived in their own homes. The average total monthly income of Rp5.733.500 is considered high as it exceeds the 2025 DKI Jakarta minimum wage (UMP) of Rp5.367.381. Meanwhile, the average total expenditure of Rp5.396.761 remains below income, indicating manageable household finances. The NTN value was 1,06 in April and 1,07 in May, resulting in an iNTN of 101%, indicating that Bouke Ami fishermen in PPN Muara Angke, North Jakarta, are at a level of economic welfare classified as prosperous with slight improvement. This increase reflects a modest rise in fishermen’s purchasing power between the two months and can serve as basis for formulating policies aimed at empowering coastal fishermen.

Environmental sanitation and hygiene are crucial for preventing skin and infectious diseases, especially in coastal areas. This has led to increased interest in developing environmentally friendly natural alternatives. Mangrove leaves have been studied for their significant antibacterial properties due to bioactive compounds such as saponins and flavonoids. Buti Village is one of the coastal villages with mangrove potential. Although several previous studies have confirmed the technical feasibility of mangrove-based products, there is limited literature on empirical dissemination strategies and community responses, particularly in the 3T (Frontier, Outermost, and Disadvantaged) areas. This study addresses this gap by evaluating dissemination strategies and community responses to innovative mangrove-based soap and hand sanitizer products in Buti Village, Merauke, South Papua. Using a quantitative descriptive approach supported by qualitative research, the study involved a purposive sample of 40 local residents. The dissemination strategy included participatory training, product demonstrations, and educational brochures. Findings showed a high level of acceptance, with 86% of respondents accepting the product, and a significant level of self-reliance, with 81% of participants able to independently produce soap and hand sanitizer products. This demonstrates that a participatory, educational, and locally-based approach is effective in building knowledge and positive attitudes toward environmentally friendly innovations. This research demonstrates that these innovations have significant potential to become sustainable community-based small businesses that can strengthen the local economy while promoting mangrove conservation.
