Abstract

This study examines the association between the adoption of mangrove-based dodol (a traditional Indonesian chewy confection) innovation and changes in economic resilience among members of the Wilmar Employees’ Wives Association (IIKW) in Dumai City, Riau Province. A quasi-experimental design combining Propensity Score Matching (PSM) and Difference-in-Differences (DID) was applied to 50 households (25 adopters and 25 non-adopters) observed before the intervention in 2021 and after the intervention in 2024. PSM was used to improve baseline comparability, while DID estimated differential changes between groups over time. After matching, the mean standardized bias decreased from 13.9% to 3.5%, and post-matching covariates were statistically balanced. The estimated DID effects were positive for monthly household income (+IDR 1.10 million; p = 0.011), income-source diversification (+1.02 sources; p = 0.034), savings share (+5.9 percentage points; p = 0.030), productive assets (+IDR 5.2 million; p = 0.016), and the Economic Resilience Index (ERI) (+0.15; p = 0.012), while the food-expenditure share declined by 7.0 percentage points (p = 0.026). These estimates suggest that mangrove-based dodol adoption was associated with improved economic resilience within the matched study population. However, the small sample limits statistical power, sensitivity to outliers, and external validity; therefore, the findings should be interpreted as localized evidence rather than population-wide effects.

Abstract

The Oesapa coastal area in Kupang City is a community-based fish landing site utilized for fish processing activities; however, its utilization has not been optimal, thereby affecting the welfare of fish-processing communities. This study aims to analyze the factors influencing the welfare of Small-Scale Fish Processing Communities and to identify the dominant factors that take priority in a risk management framework. The methods used include multiple linear regression to analyze the factors affecting the community welfare, while the House of Risk (HOR) was used to identify and prioritize risk sources. The regression showed that the welfare of fish-processing communities was significantly influenced by ecological, technological, social, and economic factors, with the regression equation Y = 7.354 + 0.136x₁ + 0.394x₂ + 0.099x₃ + 0.613x₄. Risk identification resulted in  16 risk events and 30 risk agents. HOR Phase 1 identified 20 priority risk agents, which were subsequently translated into 15 mitigation strategies. Furthermore, the ETD values obtained from HOR Phase 2 indicated that conducting regular fish processing training based on appropriate technology (P3) was the mitigation strategy with the highest (ETD) value. These findings provide a basis to establish priorities for more targeted risk mitigation programs aimed at improving the welfare of fish-processing communities.

Abstract

This study aimed to analyze the differences in conflict type and geographical location on fisheries conflict scores among traditional fishers in Larantuka District, East Flores Regency, using a two-way ANOVA approach. Fisheries conflicts in small-scale fisheries are commonly associated with competition over fishing grounds, unequal access to fishing technology, and pressure on marine resources. Primary data were collected through structured interviews with 45 traditional fishers from three coastal villages, with each respondent evaluating two categories of fisheries conflict, resulting in 90 observations included in the statistical analysis. The results showed that conflict scores differed significantly between the two fisheries conflict categories, indicating significant differences between the two categories of fisheries conflict evaluated in this study. Geographical location also differed significantly, suggesting that differences in local ecological, socio-economic, and institutional conditions contributed to variations in conflict scores among the study villages. However, the interaction between conflict type and geographical location was not significant, indicating that similar structural drivers of fisheries conflict exist across the study locations. These findings highlight the importance of strengthening equitable access to fisheries resources, improving community-based fisheries governance, and implementing adaptive fisheries management strategies to reduce fisheries conflicts in traditional fishing communities.

Abstract

Climate change increases the vulnerability of coastal fishing communities, making strengthening the blue economy through collaborative governance crucial for enhancing resilience. This study analyzes the implementation of the Pentahelix model in strengthening the blue economy as a climate change mitigation strategy in the fishing communities of South Malang. An exploratory sequential mixed-methods design was used, combining qualitative data from in-depth interviews and observations with representatives of Pentahelix actors and quantitative analysis using the Analytical Hierarchy Process (AHP). Qualitative findings indicate that although the government, academics, business actors, the community, and the media have fulfilled their respective roles, collaboration remains fragmented due to limited coordination, inadequate stakeholder participation, and inadequate integration of research findings into policy formulation. The AHP analysis produced consistent results (CR = 1.00%), indicating reliable priority rankings. Socio-economic impacts emerged as the highest-priority criterion (27.14%), while sustainable marine tourism diversification was identified as the main strategic alternative (22.34%) with a consistent ratio (CR = 1.48%). This strategy is considered capable of diversifying fishermen's livelihoods, reducing dependence on capture fisheries, and increasing community resilience while preserving coastal ecosystems.

Abstract

Sand lobster (Panulirus homarus) is a high-value export commodity, yet financial assessments of grow-out operations in Indonesia remain limited. This case study evaluated the production and single-cycle financial performance of juvenile grow-out in floating net cages (FNC) at Kampung Kerapu Beach, Situbondo, over 181 days. A total of 650 juveniles (average weight: 35 g) were stocked. Cumulative harvest yielded 500 lobsters averaging 212 g, reflecting a 76.9% survival rate. Peak mortality occurred in the first month, reaching 106 kg in total biomass. Using 2,000 kg of trash fish and shrimp heads, the feed conversion ratio (FCR) was 24.0 relative to biomass gain. Revenue reached IDR 42,400,000 against recorded costs (feed, packaging, shipping) of IDR 10,950,000, yielding a gross margin of IDR 31,450,000 and a revenue-to-cost ratio of 3.87. Unrecorded costs (seed, labor, maintenance, depreciation) mean this margin is not net profit, though it absorbs up to IDR 48,385 in unrecorded expenses per juvenile. Sensitivity analysis showed the margin was most sensitive to selling price and survival rate, remaining positive in all scenarios. Multi-cycle studies with complete cost records are needed to evaluate long-term investment feasibility.

Abstract

Consumer purchasing decisions for fishery products depend on product attributes, yet evidence on what drives consumer preference for yellowstripe scad, a widely consumed small pelagic fish in Bangka Belitung, remains scarce. This study aimed to analyze the effects of fish length, weight, price, and quality on consumer preference in Pangkalpinang. A preliminary survey was conducted among 30 consumers selected by purposive sampling at Rumput Market and the Pangkal Balam Port area. Data were analyzed using multiple linear regression after validity, reliability (Cronbach’s alpha = 0.874), and classical assumption tests (all VIF ≤ 1.342). The model was significant simultaneously (F = 3.508; p = 0.021; R² = 0.360; adjusted R² = 0.257). Partially, fish price (B = 1.264; p = 0.029) and fish quality (B = 0.864; p = 0.024) had positive and significant effects, whereas fish length (p = 0.141) and fish weight (p = 0.744) did not. These findings indicate that fish price and quality, rather than size, primarily determine consumer preference for yellowstripe scad, suggesting traders and policymakers should prioritize quality assurance and value-aligned pricing. Due to the small sample, these preliminary results require validation through larger studies.

Abstract

Shrimp is one of Indonesia's leading aquaculture commodities, with vannamei shrimp (Litopenaeus vannamei) dominating national output and export volume. However, fluctuating shrimp production in Pangkep Regency indicates suboptimal input utilization and technical inefficiency. This study evaluated technical efficiency levels while identifying key drivers of shrimp output and technical inefficiency using Stochastic Frontier Analysis (SFA) with a log-linear Cobb–Douglas specification. Empirical findings demonstrate that shrimp farmers operate with a high mean technical efficiency score of 0.819. Output is significantly affected by fry, feed, labor allocation, saponin, and fertilizer, with fry input emerging as the most sensitive factor. In Addition, technical inefficiency is significantly influenced by farming experience, stocking density, and farmer age. A returns to scale (RTS) value of 1.417 indicates that shrimp farming operates under increasing returns to scale (IRS), signaling substantial opportunities for output expansion. Maintaining rational stocking densities, optimizing input reallocation, and extending technical guidance to older and less experienced producers are recommended.

Abstract

Seagrass meadows support coastal livelihoods, but how habitat-use frequency reflects overall livelihood dependence remains insufficiently understood. We surveyed 200 fisheries-based individuals across coastal villages in the Kei Islands, Indonesia. Outcome-specific regression models examined associations between fishing strategy, seagrass-use frequency, livelihood contribution, catch quantity, gross catch value, environmental perceptions, and management support. Invertebrate/gleaning-only fishers had significantly lower odds of frequent seagrass use than finfish-only fishers (odds ratio = 0.013; 95% CI: 0.002–0.099), whereas mixed fishers showed no clear difference from finfish-only fishers. Fishing diversification showed no clear association with proportional livelihood contribution, nor did fishing strategy associate with catch quantity or gross catch value. Furthermore, associations of seagrass-use frequency and livelihood contribution with perceived environmental change, threat recognition, and management support were inconsistent across outcomes. Thus, pronounced differences in habitat-use frequency among fishing strategies do not reliably reflect other livelihood and management dimensions. Assessments of seagrass-associated fisheries should treat habitat use, livelihood contribution, fisheries outcomes, and management attitudes as complementary indicators rather than assuming a single measure represents the others.

Abstract

Mangrove restoration may improve ecological conditions without necessarily reducing livelihood vulnerability among coastal households. This study examines the relationship between ecological recovery and household vulnerability in Pangpang Bay, Banyuwangi, Indonesia, using the household component of the Social–Ecological System Vulnerability Index for Mangrove Ecosystems (SESVIME). The household component was applied because exposure, sensitivity, ecosystem dependence, and adaptive capacity were measured directly, whereas ecological indicators were derived from secondary monitoring with different spatial and temporal units. Structured interviews with 56 households in Muncar and Tegaldlimo were conducted from May to August 2026 and triangulated with restoration records and published ecological data. Household indicators were normalized to a 0–1 scale. A diagnostic additive vulnerability benchmark, [exposure + sensitivity + (1 − adaptive capacity)]/3, was compared with ordered self-perceived vulnerability using Spearman correlation. Mangrove extent increased from 643.35 ha in 2015 to 737.51 ha in 2023, while 76.8% of respondents perceived improving mangrove conditions. However, ecosystem dependence and income insecurity remained high. The additive benchmark averaged 0.603 and showed no association with self-perceived vulnerability (ρ = −0.016; p = 0.910). Given the small, nonrepresentative sample, these findings are exploratory and support integrating ecological restoration with livelihood, financial, informational, and institutional strengthening.

Abstract

The small-scale brown-marbled grouper (Epinephelus fuscoguttatus) fishery in Taka Bonerate National Park operates under intense commercial pressure driven by the international live reef food fish trade. This study evaluates the multi-dimensional sustainability index and environmental friendliness of three primary fishing gears deployed in the park’s traditional zone: handlines, fish traps (bubu), and spearguns (panah). Monitoring was conducted over 12 months by auditing a total catch sample of 1,042 specimens across three fish landing bases. A socio-technical Multi-Criteria Analysis (MCA) framework computing a standardized sustainability index (ρ) based on 14 bio-technical and socio-economic diagnostic parameters was established to resolve gear-specific compliance. Handlines achieved a sustainability score of ρ = 83.75% (sustainable category) due to high selectivity for the length at first gonadal maturity (Lm) and minimal structural reef impact. Conversely, both fish traps and spearguns scored lower at ρ = 65.62% (moderately sustainable category). The degraded performance of traps and spearguns is driven by a high catch percentage of immature fish (68.34%) and collateral damage to coral structures caused by illegal compressor-assisted fishing activities. Immediate policy interventions are required, including the mandatory implementation of escape gaps in traps, standardized hook sizes for handlines, and strict community-based monitoring to eradicate destructive fishing practices.
