Abstract

This study analyzes the factors influencing whiteleg shrimp (Penaeus vannamei) production and the efficiency of input utilization in pond farming in Bantan District, Bengkalis Regency, Riau Province. Data was collected from 40 farmers through a census approach. Data was analyzed through multiple linear regression based on the Cobb–Douglas production function, supplemented by classical assumption tests, allocative efficiency measurements, and return to scale analysis. The results indicate that key production factors include pond area, stocking density, feed quantity, pond age, and water quality. Among these, feed quantity was found to be significant (p < 0.05) and the dominant factor, with an elasticity coefficient of 0.990. The coefficient of determination (R²= of 0.989) indicates that the model explains 98.9% of the variation in production. Elasticity and allocative efficiency analyses reveal that input utilization has not yet reached optimal levels, while the estimated scale (1.118) indicates an increasing return to scale (IRS) condition. The economic implications of these findings emphasize the importance of efficient feed management to enhance productivity and income, while other factors remain relevant in supporting business sustainability. These results provide important insights for policymakers and local stakeholders to promote efficient resource allocation, strengthen farmer capacity, and develop sustainable shrimp farming strategies that improve coastal community welfare.

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

This study identifies DPSIR (Drivers, Pressures, States, Impacts, Responses) factors affecting mangrove degradation and evaluates the effectiveness of a regression-based DPSIR model in the Teluk Lembar area, West Lombok Regency. A quantitative approach was applied using field surveys and community questionnaires (n = 45) to collect biophysical and socio-economic data. Multiple linear regression was employed to examine how DPSIR pressure variables─rehabilitation frequency, community participation, land clearing, and water quality─affect mangrove biodiversity and density. Land clearing and poor water quality were the most significant predictors of mangrove degradation. The regression model for biodiversity produced R = 0.820 and R² = 0.673, while the model for density yielded R = 0.964 and R² = 0.929 (p < 0.05). These findings indicate that anthropogenic pressures strongly influence both the structural and functional aspects of mangrove ecosystems. The study demonstrates that integrating the DPSIR framework with regression analysis effectively quantifies human-environment interactions driving mangrove degradation. It recommends policy interventions emphasizing continuous mangrove rehabilitation, stricter control of land conversion, and enhanced community participation to ensure the ecological sustainability of mangrove ecosystems in coastal regions.

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

This research evaluates the effectiveness of Indonesia’s marine policies by integrating relevant socio-economic, demographic, and geographical considerations. The study was conducted across 18 Indonesian marine ecoregions, encompassing diverse coastal and archipelagic areas with varying governance characteristics. The study utilized a structured survey of 3,159 respondents to identify key governance challenges, including weak inter-agency coordination, high economic dependence of coastal communities, and implementation disparities between mainland and island regions. Instrument validity was ensured through cognitive interviews to test question clarity before distribution. Data analysis employed descriptive statistics, Pearson correlation, and multiple linear regression to quantify the relationship among policy effectiveness, communities’ economic resilience, and public support for conservation. A thematic qualitative analysis of in-depth stakeholder interviews further explored policy barriers and opportunities. Findings reveal that while communities participate in local policy initiatives (mean participation score of 3.52), their influence in decision-making remains limited (mean influence score of 3.19). Based on these evidence-based results, recommendations include enhancing institutional coordination, promoting marine-based economic diversification, and empowering coastal communities to build adaptive capacity in response to climate change and environmental degradation.

Abstract

The purpose of this study was to find out about the marketing chain of shellfish commodities in Sidoarjo. This study was conducted using survey methods, and data analysis was conducted using descriptive methods, marketing margins, and the fisherman’s share. The results of the study show that the process of catching was carried out by using dredges. The type of shellfish caught are the short-necked clam (Paratapes undulatus) and the Blood cockles (Anadara granosa and Anadara antiquta). Daily production from fishermen averages 80-100 kg/day and is dominated by blood cockles. The process of shellfish marketing is carried out by fishermen to collectors and is marketed directly to buyers. The collectors will market the shells to retailers and to restaurants. The results of this research obtained 3 types of marketing channels, namely types A, B, and C. The shortest channel types A, namely from fishermen directly to consumers, followed by type B from fishermen to collectors, retailers, and finally to consumers. While type C is the most extended marketing channel, starting from fishermen, collectors, restaurants, and the last is consumers. Type A is an effective marketing channel and efficient for fishermen because it can be obtained from them as compared to other types, and has the fisherman’s share of 42.86%.

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.

Abstract

Fisheries modernization in Indonesia is expected to improve productivity and strengthen the welfare of coastal communities. This study aimed to examine the relationship between the modernization of capture fisheries and fishers’ welfare in Pangandaran Regency. A survey of 60 fishers was conducted using snowball sampling, supported by in-depth interviews and a literature review. Modernization was measured through indicators such as capital, engine power, vessel size, and gear price, while welfare was assessed through income, expenditure, education, health, catch volume, and housing conditions. The analysis employed Spearman’s Rank correlation, complemented by qualitative evidence. The results indicated that most fishers remained at a low to medium level of modernization, while their welfare is generally in the medium category. A strong positive correlation was confirmed between modernization and welfare (ρ = 0.530; p < 0.01). These findings suggest that modernization contributes to better welfare, although the benefits are not distributed evenly, with vessel owners gaining more advantages than crew members. Policy implications highlight the importance of phased financing schemes, improved landing infrastructure, and better protection for small-scale fishers.

Abstract

This study examines community participation in the development of the Ketapang Urban Aquaculture (KUA) tourism area. Initially, this area was a poor and densely populated settlement with traditional fish ponds as the main source of livelihood. The area was revitalized through an urban aquaculture program, reorganizing residential zones, maintaining local economic activities, and converting unproductive ponds into mangrove gardens to support sustainable tourism. Using a descriptive quantitative method, data were collected from 98 residents via structured questionnaires to assess the level, pattern, and intensity of participation. Results show that 49% of respondents are at the therapeutic participation level, reflecting formal involvement with limited influence on decision-making. Despite this, the community has initiated businesses around KUA, including accommodation, culinary services, handicrafts, and fishery-based products. This study’s novelty lies in demonstrating how local initiatives can drive tourism development and economic opportunities even under limited formal authority. Findings provide guidance for enhancing collaboration between management and residents, building local capacity, and designing inclusive participatory strategies. Strengthening community involvement is vital for sustainable tourism, fostering local entrepreneurship, and promoting ownership and collective responsibility in the KUA area.
