Abstract

Betta splendens is an ornamental fish with a variety of color variations, which is one of the main factors determining its selling value. One of the variants of hippopotamus, which is currently in great demand by ornamental fish enthusiasts, is the multicolor hippopotamus. During maintenance, cupang fish often experience a decrease in color quality caused by internal and external factors. One of the efforts to improve color quality is to supplement the feed with ingredients rich in pigments, such as shrimp head flour (TKU), which contains carotenoids. This study aimed to improve the brightness and color performance of hippopotamus by adding shrimp head meal to commercial feed. The method used was a completely randomized design (CRD) with four treatments, namely, control, 5% TKU, 10% TKU, and 15% TKU, each with three replicates. The research procedure included the preparation of shrimp head meal, mixing feed with TKU, fish rearing, and observation of changes in color brightness, weight and length growth, survival rate, and water quality. The results showed that the utilization of shrimp head meal supplemented into the feed improved the performance of brightness and color patterns in multi-colored cupang fish, including length gain during the treatment, with optimum results shown in the 10% TKU treatment.

Abstract

Vocational High School (SMK) is a secondary school that aims to produce quality human resources for those who are ready to work at a productive age. SMK-level schools are inhabited by teenage children at the age–15-17 years. Teenagers at that age need adequate nutritional intake, both in quality and quantity, for their growth and development, both in terms of health and non-health. Fish is a food ingredient with a variety of health and non-health benefits. The health benefits of fish are in the form of good nutritional status, while in the non-health aspect, it improves cognitive aspects in the form of learning achievements at school. This study aimed to investigate the relationship between fish consumption, nutritional status, and learning achievement among vocational students in Mejayan Village. The study used a cross-sectional design with 177 students, and data were collected through questionnaires, anthropometric measurements of IMT/U, food recall 1 × 24 hours, and report card scores. Data analysis using the Chi-Square method The results showed that the fish consumption level of vocational high school students in Mejayan Village was low at 8.18 kg/capita/year and there was no significant relationship with nutritional status (p=0.911) or learning achievement (p=0.422). The absence of a relationship between the two variables may be due to factors other than fish consumption that influence the results. Based on this research, education on the importance of fish consumption for students is needed to increase the benefits of their nutritional and cognitive status.

Abstract

Cikidang Fishing Port is one of the fishing ports that plays an important role in capture fisheries in Pangandaran, with drift gillnet as the main fishing gear. The high use of this tool encourages the analysis of the diversity and composition of the catch to assess fishery productivity and maintain resource sustainability. This study aimed to analyze the composition and diversity of drift gillnet catches landed at the PPI Cikidang Pangandaran. The methods used include the calculation of production amount and value, Catch Per Unit Effort, percentage of catch composition, and diversity index. The data analyzed were obtained from the Cikidang PPI statistical report during the 2019-2021 period. The results showed that white pomfret (Pampus argenteus) was the most dominant species in the catch, with an average contribution of 26.4% per year, whereas yellow mackerel (Selaroides leptolepis) had the least catch (only 0.62% per year). The catch diversity index showed a value of 2.77 in 2019, 2.19 in 2020, and 2.21 in 2021, which falls into the medium category. Habitat conservation efforts and increased awareness of fishermen are also needed so that fishery resources in the Cikidang Fishing Port remain sustainable and productive in the long term.

Abstract

The Bali Strait is a marine area rich in lemuru fish (Sardinella lemuru), making it a potential fishery commodity in Indonesia. Sustainable management of lemuru fish populations in the Bali Strait is crucial for maintaining ecosystem balance and ensuring the sustainability of the fishing industry in the region. This study aimed to identify the thermal fronts in the Bali Strait and the relationship between thermal fronts and lemuru fish production. This research was conducted using monthly sea surface temperature and surface current data from the CMEMS for the year 2023, along with lemuru production data from PPN Pengambengan. An edge detection method was employed to determine thermal fronts. The results showed that sea surface temperatures ranged from 24.9°C to 29°C. The meridional movement from North to South dominates the Bali Strait surface currents. Thermal fronts were observed throughout the year, with weak fronts dominating during the west monsoon and transition season I, whereas strong fronts intensified during the southeast monsoon. However, the correlation between thermal fronts and lemuru catch was very weak (r=-0.047442), suggesting that thermal fronts are not the primary factor influencing lemuru catch.

Abstract

Fishmeal is a rich source of animal protein and essential nutrients, offering significant potential for food fortification, particularly in cookies and pastries, which are typically low in protein. This article presents a literature review of various studies evaluating the addition of fishmeal derived from local fish species such as biang, anchovy, mackerel, swanggi, and roa in the production of baked goods. The findings show that incorporating fishmeal at concentrations between 10–20% significantly increases products' protein content—for example, Swanggi fish biscuits reaching 19.91% protein and roa fish sticks reaching 15.44%. Several products also showed increased mineral content, such as calcium up to 820.63 mg/100 g. The sensory qualities remained acceptable to consumers, provided the addition levels were not excessive. A primary challenge remains the distinct fishy odor, which can affect consumer acceptance but can be mitigated through appropriate processing techniques. This review concludes that cookie fishmeal fortification is an innovative strategy for improving nutritional quality and utilizing local fishery by-products.

Abstract

This study aims to estimate the carbon stock and sequestration potential of the mangrove ecosystem along the Hitapory Coast, Kailolo Village, Central Maluku, as a critical step in supporting climate change mitigation efforts. Data collection was conducted at five stations using the quadrat transect method to measure vegetation density, stem diameter, and identify mangrove species. Biomass analysis was performed using allometric equations appropriate for the dominant species. The results indicate a total carbon stock of 330.74 tons C/ha, comprising 227.19 tons C/ha of above-ground carbon (AGC) and 103.55 tons C/ha of below-ground carbon (BGC). The estimated carbon sequestration, expressed in CO₂ equivalents, was 1,212.72 tons CO₂e/ha, with the dominant contribution from Sonneratia alba at 1,187.50 tons CO₂e/ha, while the lowest contribution was from Rhizophora stylosa at 10.76 tons CO₂e/ha. These findings highlight the significant role of the local mangrove ecosystem as an effective carbon sink. Therefore, the conservation and sustainable management of mangroves are essential to support both national and global carbon emission reduction strategies. Furthermore, the study presents an opportunity to develop policies centered on blue carbon trading as an innovative mechanism for climate change mitigation.

Abstract

Smoking is a post-harvest processing technique used to extend the shelf life and maintain the quality of fish products. In Fakfak Regency, smoked fish products are generally marketed without adequate packaging, making them prone to quality deterioration. This study aimed to evaluate the effects of packaging type (vacuum and non-vacuum), cold storage duration (4 °C), and their interaction on moisture content, pH, water activity (Aw), and organoleptic characteristics of smoked Komo mackerel (Euthynnus affinis). The experiment employed a two-factor Completely Randomized Design (CRD), with factors being packaging type (vacuum and non-vacuum) and cold storage duration (days 7, 11, 17, and 25), each treatment replicated three times. Quantitative data were analyzed using SPSS version 27 using GLM Multivariate while factor interactions were analyzed using One-Way ANOVA. If significant differences were found, further testing was performed using Duncan's Multiple Range Test (DMRT) (p < 0.05). Organoleptic data were descriptively evaluated based on color, texture, and aroma. The results indicated that the combination of vacuum and non-vacuum packaging with cold storage (4 °C) significantly affected moisture content, pH, and Aw. The interaction between the two factors was only significant for moisture content and pH, while the effect on Aw was not significant. Organoleptic observations showed that vacuum packaging was able to maintain product quality until day 24, whereas non-vacuum packaging showed quality deterioration from day 11, characterized by pale brown color, soft texture, and loss of characteristic smoked fish aroma. In conclusion, vacuum packaging is more effective in extending the shelf life and maintaining the quality of smoked Komo mackerel compared to non-vacuum packaging under cold storage conditions.

Abstract

Pallime and Pusungnge villages are key production centers for mud crabs, serving both local consumption and export markets. This study aims to assess the competitive advantage of mud crab commodities, focusing on productivity, quality, continuity, and marketable pricing. The research was conducted from May to July 2025 in Pallime and Pusungnge villages. A qualitative method was employed, utilizing both primary and secondary data collection techniques. The results indicate that in the mud crab value chain of Pallime and Pusungnge, four main actors are involved: fishers, farmers, and collectors. Female crabs consistently fetch higher prices than male crabs. The price difference between farmers and collectors to consumers indicates that collectors obtain the highest profit margins within the mud crab distribution chain. Four types of marketing channels were identified: fishers selling directly to consumers, farmers selling directly to consumers, farmers selling to collectors, and collectors selling to traders before the products reach end consumers. A subsequent SWOT analysis identified key strengths, such as supportive mangrove ecosystems; weaknesses, including limited access to modern technology; opportunities, such as domestic and export market demand; and threats, such as environmental degradation. By leveraging strengths and opportunities while addressing weaknesses and threats, the mud crab value chain can be significantly enhanced.
