Abstract

This study aims to analyze the distribution of coral reef cover in North Aceh Waters using a Geographic Information System. This research was conducted from December 2025 to January 2026 in North Aceh Waters. Primary data collection in the field focused on in-situ water quality measurements, identification of benthic cover using Underwater Photo Transect (UPT), inventory of associated biota through visual censuses, and data collection of coral distribution coordinates. All data were then analyzed comprehensively through evaluation of quality standards for water quality, quantification of the percentage of coral cover using CPCe software, and spatial modeling of its distribution based on ArcGIS 10.8. The observation results show that the water quality including depth, temperature, salinity, pH, and DO are classified as suitable for coral reef growth in North Aceh Waters. The distribution of coral reef cover at station 1 consists of Coral namely Table Coral (Acropora sp.), Brain Coral and Massive Coral (Porites sp.), Bowl Coral (Turbinaria sp.), Encrusting Coral, various associated biota from invertebrate groups and marine flora such as blue starfish (Linckia laevigata), chicken feather anemones, and red algae. Meanwhile, at station 2, coral reef types were found consisting of Massive Coral (Porites sp.), Brain Coral (Favia sp.), Table Coral (Acropora hyacinthus), Sheet Coral (Echinopora sp.), Foliose Coral (Montipora foliosa), Encrusting Coral, and other biota were found in the form of sponges (Xestospongia muta), sea anemones, and sea cucumbers (Holothuroidea).

Abstract

Fish is an important food for their essential nutrients and has numerous health benefits. However, fishery products are highly perishable and prone to rapid quality deterioration. Although the use of formalin as a food preservative is prohibited, it is still frequently detected in fishery products. This study aims to determine formalin levels and evaluate the organoleptic characteristics of various fresh fish species sold at traditional markets in Serang City. The study used observational methods with purposive sampling. Formalin content was analyzed qualitatively, while organoleptic characteristics were assessed using hedonic testing based on appearance, gills, mucus, flesh, odor, and texture. The results showed that 3 out of 10 fish species tested positive for formalin: Milkfish, Tilapia, and Flounder fish. For Tilapia, the average scores were 6.99 (positive) and 6.48 (negative). For Flounder fish, the scores were 6.69 (positive) and 7.05 (negative). According to the Indonesian National Standard, the average organoleptic scores of milkfish (both positive and negative) and negative formalin flounder fell into the “Fresh Fish” category. Overall, there was only a slight difference in organoleptic scores between fish containing formalin and those without, making them difficult to distinguish by sensory evaluation alone.Keywords: fishery product, flounder fish, organoleptic, perishable, qualitative

Abstract

Lamalera fishermen in Lembata Regency traditionally hunt sperm whales (Physeter macrocephalus) and preserve the blubber by sun-drying it on the beach prior to barter trading. The oil extracted from this blubber is typically characterized by a strong fishy odor. This study aims to determine the quality of sperm whale oil produced through this traditional preservation method. The research employed an experimental method. Solid blubber samples (221.34 g) were processes using thermal extraction to obtain the oil. The research procedure included sample preparation, thermal extraction, and analysis of physical and chemical properties with all experimental performed in triplicate. Physical analyses included oil yield, moisture content, and density, while chemical analyses comprised free fatty acid (FFA) content (by alkalimetric titration), saponification value (by acid–base titration), and iodine value (by Wijs method). The results showed an oil yield of 76.65%, moisture content of 1.43%, and density of 1.051 g/mL at 32°C. Chemically, the oil had a free fatty acid (FFA) content of 8.95%, saponification value of 80.41 mg KOH/g, and iodine value of 9.86 g I₂/100 g oi1l.

Abstract

This study elaborates the effect of different rearing container colors on the survival rate and growth performance of Tor douronensis juveniles. The experiment was conducted for 90 days using a Completely Randomized Design (CRD) with five treatments and three replications. The treatments consisted of transparent, orange, yellow, blue, and dark green container colors. The observed parameters included survival rate (SR), daily weight growth (WGR), daily length growth (LGR), specific growth rate (SGR), condition factor (K), coefficient of variation (CV), feed conversion ratio (FCR), and water quality. Result revealed that container color significantly affected (P<0.05) survival rate and most growth parameters, while no significant effect was observed on FCR (P>0.05). The yellow container treatment consistently showed the best performance, with the highest LGR (5.34±0.06 mm/day), SGR (2.29±0.04%/day), and survival rate (98.67±2.31%). Bright-colored container enhanced fish visibility and feeding efficiency, leading to better growth and reduced stress. In contrast, darker-colored container resulted in lower performance, presumably due to reduced light reflection and increased stress levels. Water quality parameters remained within the optimal range throughout the study, indicating that container color was the primary factor influencing fish performance. In conclusion, bright-colored container, particularly yellow, significantly enhanced the survival rate and growth performance of Tor douronensis juveniles. Manipulating container color is a simple and cost-effective strategy to improve productivity in freshwater fish farming. Keywords: Tor douronensis, container color, growth, survival

Abstract

The Industrial Revolution shifted production toward mechanization, significantly increasing fuel oil (BBM) dependency in Indonesia's fishing sector, particularly for lift net (bagan) operations. Bagan fishermen rely on generators (gensets) to power lamps that attract fish, yet the resulting exhaust emissions threaten environmental quality and climate stability. This study aims to analyze fuel consumption and emissions from gensets used in lift net fishing in Pagatan, South Kalimantan. Using a descriptive quantitative approach, primary data were collected through field observations of lift net units. The results revealed that one Lift net unit consumes approximately 1,000 liters of Pertalite per year, generating 2,300 kg of CO2 emissions annually. Collectively, the 200 units in Pagatan produced 460,000 kg of CO2 per year. These substantial emissions contribute significantly to air pollution and climate change, with CO2 levels reaching 700 ppm potentially impair human cognitive function and physiological health. These findings underscore the urgent need for a transition to eco-friendly alternative energy sources to support government programs in reducing pollution and mitigating climate change impacts in the fisheries sector.keywords: Carbon dioxide; Emissions; Fuel consumption; Generator, Lift net

Abstract

Scad fish (Decapterus sp) is a high-value pelagic fishery commodity in Indonesia, widely known for its abundance and high nutritional content. However, different drying methods can significantly affect its nutritional quality. This study aims to determine the effect of drying methods on the nutritional composition of Scad fish. The research employed a comparative study with two treatments: traditional sun-drying and oven-drying. The study was conducted in October 2024, with sample preparation carried out at the Larantuka Institute of Teacher Training and Technology, and nutritional analyses performed at the Feed Chemistry Laboratory of Nusa Cendana University, Kupang. The analyses were conducted using standard methods: gravimetric for moisture content, dry combustion for ash content, Soxhlet for fat content, Kjeldahl for protein content, and by-difference calculation for carbohydrate content. The results demonstrated that drying methods significantly affected moisture, ash, fat, protein, and carbohydrate content of the Scad fish. The oven-drying method yielded the best nutritional profile, with moisture content of 14.337%, ash content of 36.00%, fat content of 9.187%, protein content of 53.262%, and carbohydrate content of 1.551%.Keywords: Decapterus sp; gravimetri; kjeldahl; Oven; Soxhlet: Solar Thermal

Abstract

Gastropods are the largest class of Mollusk, and represent one of the important non-fish biological resources. These invertebrates exhibit a remarkable ability to adapt to a wide range of environmental conditions, such as extreme temperatures and salinity levels. Their abundance and diversity are influenced by several factors including environmental conditions, food availability, predation, and competition. This study aims to examine the species diversity of gastropods in the Waters of Waitiu, East Flores Regency. Environmental parameters measured included pH, temperature, and salinity. The study was conducted at one observation station in the intertidal zone. Three line transects were laid perpendicular to the coastline at 50 m intervals. Each transect consisted of three 1x1m2 sampling plots, resulting in a total of nine plots. Gastropod species were identified using gastropod diversity book. The results indicated that the abiotic parameters in Waitiu waters were favorable for gastropod life, with a pH of 7.2, temperature of 28°C, and salinity of 35 ‰. A total of 338 individuals from 14 families and 29 species were recorded, with Hebra Corticata being the most dominant species. The uneven distribution of individuals was influenced by environmental factors affecting the community structure, including dominance, and species diversity. The results of diversity measurements using the Shannon-Wiener index showed an H' value of 2.073, indicating moderate diversity.

Abstract

The fourfinger threadfin (Eleutheronema tetradactylum) is an economically important but increasingly threatened species classified as Endangered on the IUCN Red List. This study examined biological aspects of E. tetradactylum in the waters of Mendahara Ilir, East Tanjung Jabung Regency, Jambi. The research focused on the length-weight relationship (LWR), condition factor (K), relative weight (Wr), and size-based fishing eligibility. A total of 340 specimens, consisting 161 males and 179 females, were collected using gill nets. The LWR equations revealed  W = 0.002444L3.3306 (R² = 0.9571) for males and W = 0.005523L3.1116 (R² = 0.9623) for females, indicating positive allometric growth in males and near-isometric growth in females. The t-test confirmed that both b values differed significantly from 3 (p < 0.001). The mean condition factor (K) was 2.83 ± 0.14 for males and 2.91 ± 0.07 for females, while the mean relative weight (Wr) was 101.46 for males and 100.98 for females, indicating good physiological condition and favourable habitat quality. However, analysis of fishing eligibility revealed that only 48.60% of female fish had reached the minimum catchable size (Lc = 40.0 cm), compared to 72.05% of males that exceeded their threshold (Lc = 29.0 cm). The high proportion of undersized female fish raises serious concerns about potential recruitment overfishing. These findings underscore the urgent need to implement for size-selective fishing regulations in Mendahara Ilir waters.
