Abstract

The critical condition of Lake Tempe has undergone comprehensive changes over the last 10 years. Fisheries management strategy indicators with an appropriate ecosystem-based approach can reduce and prevent unbalanced environmental impacts. This research analyzes fisheries management using the Ecosystem Approach Fisheries Management (EAFM) module, the Rapid Appraisal for Fisheries Sustainability (RAPFISH) method. Six important statuses and dimensions used as attribute indicator analysis in this research are fish resource dimensions, habitat dimensions, fishing technique dimensions, economic dimensions, social dimensions, and institutional dimensions. The analysis results show that the fishery management status value for Lake Tempe is 36.072 in the unsustainable category. Based on the RAPFISH analysis, namely: (1) Economic dimensions 21.390 in the unsustainable category, (2) Habitat dimensions 36.050 in the unsustainable category, (3) Fish resource dimensions 24.483 in the moderately sustainable category, (4) Fishing technique dimensions 42.180 in the moderately sustainable category, (5) Institutional dimensions 48.070 categories are quite sustainable (6) Social dimensions 45.590 categories are quite sustainable. Based on the AHP analysis, habitat dimensions, protection of important zones for spawning grounds, nursery grounds, and water hyacinth cover problems are identified.

Abstract

Shrimp is one of Indonesia's leading fishery commodities. Vaname shrimp is the most widely cultivated type of shrimp. Shrimp production fluctuates every year. West Java is one of the shrimp centers that experienced a greater decline in production compared to other shrimp center provinces. This decline in production may be attributed to a failure to achieve technical efficiency. This study aims to determine the technical efficiency level by including variables affecting production and technical efficiency. This study was conducted in Indramayu Regency, which is one of the shrimp centers in West Java. This study employs the Stochastic Frontier Analysis (SFA) method, utilizing the Cobb-Douglas production function. The results showed that shrimp farmers in Indramayu Regency are technically efficient, with an efficiency value of 0.83. Factors affecting production are fry, feed, in-family labor, out-of-family labor, and water pumps. Factors affecting technical efficiency are age, experience, number of dependents, and capital sources. This study suggests that feed is the most responsive variable to production, so good feed management is needed. Young farmers are more efficient, so this business can be an alternative for the younger generation

Abstract

This study investigates the effectiveness of Submersible Attractor Lights (SAL) in improving the economic productivity of gillnet fisheries in the Madura Strait. Using experimental methods over a two-month period, this research compares catch results with and without SAL, focusing on the quantity, weight, and diversity of fish caught. The test results (U = 365.0, p = 0.0000086) indicate a statistically significant difference between gillnet catches with and without SAL. The findings reveal that SAL increases the economic value of the catch by 84.13%, demonstrating significant improvements in both productivity and profitability. Species such as Indian Mackerel (Rastrelliger kanagurta), Bigeye Scad (Selar crumenophthalmus), and Great Barracuda (Sphyraena barracuda) exhibited notable economic contributions when SAL was employed. Additionally, SAL reduced operational inefficiencies by attracting fish closer to the nets, thereby optimizing fuel and time usage. The study also acknowledges the upfront cost of SAL and operational expenses, which are outweighed by the substantial economic benefits. This research emphasizes SAL as a sustainable technological innovation with potential applications in small-scale fisheries to enhance both economic and environmental outcomes.

Abstract

The small-scale capture fisheries sector is vital to the economy of Raja Ampat Regency. Still, it faces sustainability challenges, including ecological pressures, limited access to technology, low welfare among fishers, and weak governance. The objective of this study is to evaluate the sustainability status of small-scale capture fisheries in Raja Ampat based on five dimensions: economic, ecological, social, technological, and legal and institutional. The Rapid Appraisal for Fisheries technique was employed to analyze sustainability in a multidimensional manner, followed by Monte Carlo and Leverage analysis to identify leverage attributes in each dimension. Results show that the ecological and economic dimensions are moderately sustainable, while the social, technological, and legal and institutional dimensions are less sustainable. Key leverage attributes include fish size, fishing time, and species variability in ecology; fisheries marketing, business capital, additional income, and subsidies in the economy; regulation compliance and fisher group roles in social aspects; selective fishing gear and quality management in technology; and law enforcement, rule dissemination, and institutional guidance in the legal and institutional dimension. Enhancing these attributes is expected to support the sector's sustainability in Raja Ampat.

Abstract

This study aimed to evaluate the techno-economic feasibility of reintroducing sail propulsion on the traditional "Ijon-Ijon" fishing boat in Lamongan, East Java. The methodology involved numerical calculations and ship modeling to determine vessel resistance and sail-generated thrust. A 76 m² triangular sail was designed and analysed using established aerodynamic principles. The results showed that the sail generated a thrust of 85.6 N, 135 N, and 323 N at wind speeds of 4 m/s, 5 m/s, and 8.245 m/s (16 knots), respectively, enabling the vessel to achieve speeds exceeding 4.5 knots in good wind conditions. The economic analysis projects monthly fuel cost savings of IDR 1,315,800 at 16 knots and IDR 2,652,000 at 30 knots. In conclusion, reintroducing sail propulsion is a viable strategy for reducing operational costs and enhancing sustainability in Indonesia's traditional fisheries sector.

Abstract

This study aims to analyze the pattern of patron-client relationships between senangin (Eleutheronema tetradactylum) fishermen and tauke (capital owners) in Rokan Hilir Regency, Riau Province, Indonesia. The research employed a qualitative approach using primary data obtained through direct interviews with fishermen, tauke, and related stakeholders, and secondary data collected from government institutions and statistical reports. The findings reveal that fishermen depend heavily on tauke due to limited capital and restricted market access. Tauke provides fishing facilities, such as operational costs, boats, and fishing gear, while fishermen are bound to sell their catches exclusively to the tauke. This relationship includes both economic aspects (capital support and profit-sharing system, with 75% of catches going to fishermen and 25% to tauke) and non-economic aspects (loans during lean seasons, assistance in emergencies, trust, and loyalty). The study concludes that the patron-client relationship forms a reciprocal yet asymmetric dependency, where fishermen gain access to capital and markets, while tauke maintains control over fish pricing and distribution. Institutional strengthening and alternative financial mechanisms are recommended to reduce fishermen’s dependency and promote sustainable fisheries management.

Abstract

The traditional knowledge system of cage cultivation reflects the local wisdom of the coastal communities of Sentani Lake, which needs to be documented for the sustainability of traditional livelihood practices. This study aims to analyze the process of constructing fixed net cages (KJT) and floating net cages (KJA), cultivation techniques, and obstacles faced by cultivators. A qualitative descriptive study was conducted in Asei Kecil Village, East Sentani District, from May to August 2023 with six informants (one traditional leader and five cultivators with >2 years of experience) through purposive interviews, participatory observation, and documentation. The results show that the community has mastered cage construction using ironwood for KJT and KJA using traditional techniques. Cultivation practices include selecting quality seeds, providing natural and artificial feed, and gradual harvesting techniques. However, cultivators face obstacles such as environmental fluctuations, predator attacks, and fish theft. Therefore, cultivation requires strengthening the cage security system and knowledge transfer in the form of training on fish disease prevention.

Abstract

Income inequality of fishermen’s households reflects the distribution of income among families who depend on the fisheries sector as their main source of livelihood, as well as additional income from other sectors that have the potential to create economic inequality or equality. This study aims to analyze the distribution of income of fishermen's households in Sungai Kakap Village, Sungai Kakap District, Kubu Raya Regency, West Kalimantan. The method applied in this study is descriptive with a quantitative approach. The research sample consisted of 90 fishermen's households in Sungai Kakap Village. The income of fishermen's households in Sungai Kakap Village is significantly influenced by seasonal changes in fishing activities, which are divided into two periods, namely the harvest season (April-September) and the lean season (October-March). To measure income inequality, the Gini Coefficient and Lorenz Curve are used. Based on the results of the Gini Ratio calculation, the distribution of income of fishermen's households in Sungai Kakap Village has a value of 0.184, which indicates a low level of inequality so that it is known that the income of the fishermen community in Sungai Kakap Village is almost evenly distributed by working as fishermen.

Abstract

Small-scale fisheries are an important sector that contributes to increasing food security, alleviating poverty, and escalating employment opportunities. However, the magnitude of this contribution is not in line with the condition of small-scale fishermen who are still trapped in marginal and underdeveloped conditions and depend on natural resources to fulfill their daily lives. Climatic, social, economic, and technological variability also pressures fishermen's lives. Structural burdens, marginalization, and underdevelopment can make fishermen vulnerable to change and unexpected events. This research uses SEM-PLS to simultaneously test the influence of livelihood capital on the adaptive capacity of small-scale fishermen. The results show that spatial properties have the greatest influence to technological capital. Psychological capital has been proven to be the strongest factor that directly increases adaptive capacity. Furthermore, human capital acts as a key mediator linking the influence of spatial properties on adaptive capacity. This finding emphasizes that improvements in spatial properties supported by human capital can encourage the use of technology and psychological resilience, thereby increasing fishermen’s adaptive capacity. The results of this study have implications for enriching the literature on the implementation and exploration of multidimensional livelihood capital held by fishermen in coastal areas to achieve sustainable livelihoods for fishermen in developing countries.

Abstract

Solar energy is a new innovation in aquaculture. The purpose of this study was to determine the economic benefits and energy efficiency of using solar panel energy on paddle aerator machines in shrimp ponds. The research method employed was a causal ex-post facto design. The variables observed were the electricity consumption of paddle aerators using solar energy compared to those using conventional energy sources. The research findings indicate that the oxygen production rates of paddle aerators were 2.04-2.77 mgO2/hour (solar panel) and 2.02-2.89 mgO2/hour (non-solar panel). Solar panels generated electrical energy in paddle aerators at rates of 8.34-8.75 watts. Electricity consumption by paddle aerators was recorded at 7.10-8.65 kW (solar panel) and 6.89-9.28 kW (non-solar panel). Quantitatively, the efficiency of electricity was found to be 0.10-1.24 watts when using solar panels. The use of solar panels is also considered more cost-effective for operational costs in intensive shrimp farming. Conclusion, the use of solar energy via solar panels for paddle aerators proves highly effective and economical compared to conventional electricity sources. Additionally, this system supports the operational effectiveness of the equipment throughout its technical lifespan.
