Abstract

Aquaculture technology to increase productivity includes sex reversal or masculinization. Masculinization of snakehead fish (Channa striata) is essential to balance the male sex ratio for sustainable aquaculture. One approach is the use of natural compounds to reduce dependence on synthetic hormones that are less environmentally friendly. Natural substances such as mangosteen peel extract (Garcinia mangostana) contain aromatase inhibitors. This study aimed to determine the optimal dosage of mangosteen peel extract for inducing sex reversal in snakehead fish. Two-week-old fry were immersed in different treatments (control 0 g/L, 0.5 g/L, 0.7 g/L, and 0.9 g/L) for 4 hours and reared for 2 months. Gonads were examined microscopically using aceto-carmine staining. Results showed that the highest male proportion was obtained at 0.9 g/L, while the highest survival rate was recorded at 0.7 g/L. The Kruskal–Wallis test (H=7.64; p=0.054) indicated no significant differences among treatments in male proportion. The Mann–Whitney U test (p=0.077) between control and each treatment confirmed that formal differences were not significant, although a trend of increased male proportion was observed across all treatments. One-way ANOVA (F=16.72; p=0.0008) demonstrated that treatment doses significantly affected survival. Tukey HSD revealed that all treatments differed significantly from control (p<0.05), while no significant differences occurred among treatment doses (p>0.05). In conclusion, doses of 0.5–0.9 g/L were effective in promoting masculinization while maintaining optimal survival in snakehead fish.

Abstract

The Klawing River plays an essential role as a source of livelihood for local communities and as a habitat for various fish species, yet it is increasingly under pressure from human activities and environmental changes. This study aims to identify the forms of local wisdom practiced by fishing communities in managing fishery resources and to assess their relevance to modern challenges. The research was conducted in five villages representing the upstream, middle, and downstream sections of the river using a qualitative descriptive approach through interviews and observations involving 40 respondents. The results show that local wisdom is reflected in the use of traditional fishing gear (nets, gillnets, fishing lines, paser, wuwu, and mijahan), the application of the pranata mangsa as a seasonal fishing guide, social solidarity among fishers, and the Gredug Sampah tradition focused on maintaining river cleanliness. These practices now face limitations due to climate change, the introduction of invasive species, and economic pressures. The declining accuracy of the pranata mangsa indicates the need to integrate traditional ecological knowledge with modern climatological information to enhance community adaptation to ecosystem dynamics. Therefore, the synergy between local wisdom and scientific approaches is crucial for achieving an adaptive and sustainable fishery resource management system in the Klawing River.

Abstract

The traditional fishing practice of Talikor is an integral cultural heritage for the Duan Lolat community in the Tanimbar Islands Regency, but it now faces the threat of degradation due to modernization. This research addresses the dual challenges of cultural practice erosion and the need for sustainable economic opportunities for the local community. Its main objective is to develop and empirically validate an integrative model to revitalize Talikor as a sustainable community-based ecotourism initiative. Adopting a mixed-methods design, this study collected data through surveys (N=100), in-depth interviews, and Focus Group Discussions (FGDs). Quantitative data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the causal relationships within the proposed model. The main findings show overwhelming community support, with 95% of respondents agreeing to the development of Talikor ecotourism. The statistically validated model was able to explain 68.89% of the variance in the model's sustainability (R^2 = 0.6889). The strongest causal relationship was identified between Identity Strengthening and Economic Empowerment (β = 0.52, p < 0.001), which underscores the importance of cultural pride as a foundation for economic development. The main contribution of this research is the provision of an empirically validated and community-supported framework that bridges cultural preservation with economic development. This model offers actionable insights for policymakers and development practitioners to revitalize similar cultural heritage as sustainable economic assets.

Abstract

This study aimed to evaluate the effectiveness of Ketapang (Terminalia catappa), Banana (Musa sp.), and Teak (Tectona grandis) leaf extracts on enhancing the coloration of Channa maru (Channa marulioides). Body coloration in ornamental fish is an important aesthetic trait that significantly influences market value and consumer preference in the ornamental aquaculture industry. The experiment was conducted using a completely randomized design (CRD) consisting of four treatments (control, Ketapang extract, Banana leaf extract, and Teak leaf extract) with three replications. Parameters observed included color intensity using the Toca Colour Finder (TCF), carotenoid content in fish tissues, survival rate, absolute growth in length and weight, and water quality. The results showed that Ketapang leaf extract significantly improved fish coloration, yielding the highest TCF scores and carotenoid content (0.32 µg/g), followed by Teak leaf extract (0.22 µg/g), Banana leaf extract (0.07 µg/g), and the control (0.06 µg/g). Leaf extracts had no significant effect on survival rate or absolute growth in length and weight. Water quality remained within the optimal range throughout the experiment and did not act as a limiting factor. In conclusion, Ketapang leaf extract is recommended as the most effective natural additive to enhance the coloration and carotenoid content of Channa maru, followed by Teak leaf extract, while Banana leaf extract showed less effectiveness.

Abstract

Environmental stressors are external factors that can negatively impact aquatic life, especially fish, as they are considered the main indicators of ecosystem health due to their sensitivity to environmental changes. The purpose of this study was to determine the level of stress in fish (especially catfish and tilapia) based on the blood glucose concentration of fish cultivated in Magelang Regency, Central Java. The data analysis used was spatial analysis to describe the spatial conditions of topographic parameters, air temperature, pond water temperature, and blood glucose concentration of fish (tilapia and catfish). Crosscorrelation multiple variable analysis was used to determine the correlation coefficient value between each parameter. The Crosscorrelation Multiple Variable Analysis method with the Pearson Product-Moment Correlation model. The results of the analysis of blood glucose concentration of catfish were 59.59 mg/dL and tilapia 87.80 mg/dL, so in general it can be concluded that the influence or correlation between water parameters on the level of stress of fish in the Magelang Regency area is tiny, which indicates that the condition of catfish and tilapia is not experiencing stress, where the average blood glucose is still at a normal level. The correlation coefficient value between water temperature and blood glucose of tilapia is -0.06, and that of catfish is -0.41, which means that the relationship between pond water temperature and stress levels of tilapia and catfish is fragile.

Abstract

Commodity balance is a collection of data and information that describes the consumption and production conditions of a particular commodity, both to meet the needs of the community and the industrial sector in a certain period of time and applies nationally. Analysis of the tuna commodity balance in Indonesia is very important to understand the balance between production and consumption and its impact on fisheries policy and the national economy. In addition, forecasting tuna production and consumption also plays a crucial role in ensuring resource sustainability and market balance in the future. However, issues such as overfishing, infrastructure limitations, and low domestic consumption pose significant challenges that need to be addressed. Therefore, the objectives of this study are: (1) analyze the tuna commodity balance in Indonesia, and (2) forecast tuna production and consumption in Indonesia. This research takes the object of Indonesia to Japan. The data used is quantitative with secondary data sources from Badan Pusat Statistik (BPS) and Kementerian Kelautan dan Perikanan (KKP) from 1994 - 2023. Time series data for 30 years were analyzed using quantitative methods with a descriptive approach for commodity balance analysis and ARIMA models for forecasting tuna production and consumption in Indonesia, selected based on stationarity tests, ACF-PACF plots, and the lowest AIC, SC, and HC criteria. The ARIMA (1, 1, 0) model was selected as the best model for production, while ARIMA (0, 1, 1) was chosen for consumption. Forecasting using ARIMA indicates an upward trend in both tuna production and consumption from 2024 to 2030. Policy recommendations for the government to improve production efficiency, strengthen product quality according to export standards, and expand domestic market access to increase national tuna consumption.

Abstract

This study presents the design and performance evaluation of a Hybrid Renewable Energy System (HRES) integrating a mini solar panel, lithium-ion battery, and seawater-based galvanic cell (Mg–Cu) for sustainable lighting applications on small fishing boats in coastal West Kalimantan, Indonesia. The system aims to provide an affordable and renewable power source for traditional fishermen. Experimental results show that a 2 W mini solar panel produced an average of 12.64 Wh/day with a peak output of 2.7 W under optimal sunlight conditions. The lithium-ion 3S 18650 battery pack (27 Wh) demonstrated stable performance, powering a 3 W HPL lamp continuously for 12 hours (18:00–06:00) with load voltage decreasing gradually from 3.36 V to 3.15 V and current from 0.78 A to 0.66 A, corresponding to a light intensity reduction from 2538 lux to 1882 lux at a 10 cm distance. In contrast, the Mg–Cu seawater cell produced lower illumination levels of 492–221 lux, indicating its suitability primarily as a backup energy source. The hybrid configuration effectively enhanced system reliability and operational sustainability in maritime environments. Overall, this study confirms the potential of HRES to strengthen energy independence among small-scale fishermen while supporting SDG 7 (Affordable and Clean Energy), SDG 13 (Climate Action), and SDG 14 (Life Below Water) through practical utilization of locally available renewable resources.

Abstract

The skin of payus fish (Elops hawaiensis) is a by-product of the bontot processing industry in Pontang, Serang Regency, Banten, which has the potential to be utilized as an alternative source of halal gelatin serving as a stabilizer in panna cotta desserts. This study aimed to characterize gelatin extracted from payus fish skin and to determine the optimal concentration of payus fish skin gelatin on the characteristics of panna cotta dessert products. The method used was a Completely Randomized Design (CRD) with one treatment factor, namely the concentration of payus fish skin gelatin at 0.5%, 1%, and 1.5%, and a control using commercial bovine gelatin. Gelatin analysis included yield, proximate composition, pH, and viscosity, while panna cotta analysis included gel strength, proximate composition, and hedonic tests on appearance, aroma, taste, and texture. The results showed that payus fish skin gelatin contained 7.7% moisture, 1.04% ash, protein 74% (bk), fat 8.4%, pH 6.3, 0.15% carbohydrates, and viscosity of 3.8 cP, which met the Indonesian National Standard (SNI) 06-3735-1995. The application of payus fish skin gelatin in panna cotta at a concentration of 1% produced the best treatment, with gel strength of 639.3 g bloom, moisture content of 75.1%, ash 3.5%, protein 5.5%, fat 1.8%, and carbohydrates 14.1%. The hedonic test results for appearance (4.03), texture (3.9), aroma (4.13), and taste (3.50) indicated that the product was rated from neutral to liked by the panelists. Therefore, payus fish skin gelatin at an optimal concentration of 1% had potential as an alternative to commercial gelatin in panna cotta dessert products.

Abstract

The Nusantara Fishing Port (PPN) Kejawanan is located in the Lemahwungkuk District of Cirebon City. Cast nets are a widely used fishing gear for catching squid. This study aims to describe how cast nets are operated and to analyze variations in squid catch productivity per trip and per gross tonnage (GT) of the vessel. The method used was a survey method through direct observation and interviews to obtain technical data on fishing operations and catch results. Observations were made on seven (7) cast net vessels per month (n = 7 vessels/month) during the period January–March 2024. The results of the study show that during January–March 2024, the highest productivity value occurred in January at 7,349 kg/trip and the lowest value was 6,224 kg/trip in February. Meanwhile, the highest productivity per GT of vessel catch was in January at 183.73 kg/GT of vessel, and the lowest was in February at 121.02 kg/GT. This variation in productivity between months occurred in the context of the season and was related to a combination of technical operational factors and fishing environmental conditions.
