Abstract

Nile tilapia (Oreochromis niloticus) is one of the leading aquaculture commodities in Indonesia, valued for its high economic potential and growing market demand. The success of tilapia farming is highly influenced by optimal water quality, particularly the level of dissolved oxygen (DO), which plays a crucial role in supporting the metabolic and physiological processes of the fish. One commonly used technology to maintain DO levels is the diffusion aerator system, whose efficiency is strongly affected by the design and diameter of the diffuser. This study aimed to analyze the effect of diffuser diameter variation on water quality and tilapia growth performance, and to determine the most effective diameter for maintaining optimal rearing conditions. The experiment was conducted over 45 days using a completely randomized design (CRD) consisting of six treatments and three replications: (A) stone aerator (control), and custom-made diffusers constructed from used tires with diameters of (B) 1 inch, (C) 2 inches, (D) 3 inches, (E) 4 inches, and (F) 5 inches. Observed water quality parameters included temperature, pH, DO, ammonia, nitrite, and alkalinity. Growth performance indicators measured included specific growth rate (SGR), daily feed intake, feed conversion ratio (FCR), and survival rate. The results indicated that all treatments-maintained water quality within optimal ranges for tilapia culture. However, no significant differences (p > 0.05) were observed in growth performance across treatments. These findings suggest that tire-based diffusers can serve as effective, economical, and environmentally friendly alternatives to conventional aeration systems in tilapia aquaculture.

Abstract

Way Kuala River is one of the rivers located in urban areas and utilized by various activities around it. Waste from the activities of the surrounding community that was discharged directly into the river will cause a decrease in river water quality. A decrease in water quality can be indicated by changes in physical, chemical, and biological parameters. The purpose of this research is to analyze water quality conditions and determine the water quality status of Way Kuala River, Bandar Lampung City. This research was conducted in November 2024-January 2025 in Way Kuala River, Bandar Lampung City. Sampling was conducted at 3 stations along the Way Kuala River using a direct survey method. Samples were then analyzed in situ, namely direct analysis in the field and ex situ with analysis at the BSPJI Bandar Lampung Laboratory. The data analysis used is STORET, pollution index (IP), and canadian council of ministers of the environment (CCME WQI). The results showed that the condition of Way Kuala River was categorized as polluted. The water quality status of Way Kuala River with STORET tends to be heavily polluted. The water quality status of Way Kuala River with IP tends to be lightly polluted. The water quality status of Way Kuala River with CCME WQI tends to be less polluted.

Abstract

Mitochondrial DNA (mtDNA)-based genetic analysis is important for revealing evolutionary relationships, supporting taxonomy, and providing a basis for conservation management. This study was conducted in the waters of Aceh Jaya and West Aceh, two regions with high shark fishing activity but minimal genetic data. A total of 12 shark individuals (6 per location) were collected from fish landing ports, then dorsal muscle tissue was taken, preserved in ethanol, and analyzed using DNA extraction, sequencing, and bioinformatics methods. Molecular identification through comparison with GenBank showed a very high level of similarity (Query Cover 99–100%, Identity 100%), with detected species including Carcharhinus falciformis, Sphyrna lewini, and Hemigaleus microstoma, reflecting a wide distribution in the western waters of Aceh. The nucleotide composition showed a dominance of thymine bases and a higher A+T ratio than G+C, consistent with the characteristics of shark genomes. Phylogenetic analysis showed a monophyletic clade with strong bootstrap support (100%) and placed S. lewini as the earliest differentiated taxon. Our results confirm the efficacy of DNA barcoding for accurate species identification and genetic diversity mapping, while underscoring urgent conservation concerns, as most species identified are classified as Vulnerable to Critically Endangered on the IUCN Red List.

Abstract

Intensive whiteleg shrimp farming has the potential to degrade water quality through the accumulation of organic matter and nutrients in coastal ecosystems. This study aimed to evaluate differences in water quality between estuarine and marine waters in Bireuen Regency, Aceh, and to associate them with plankton and bacteria as ecological indicators. The research was conducted from July to August 2025 at three estuarine and three marine stations, analyzing physical, chemical, and biological parameters. Results showed that estuarine waters had higher TSS (9–16 mg/L), NH₃ (0.80 mg/L), BOD (4.6–7.1 mg/L), and COD (32–33 mg/L) than marine waters, associated with the presence of Nitzschia spp., Ceratium hirundinella, Brachionus rotundiformis, Aeromonas hydrophila, and Vibrio parahaemolyticus. In marine waters, although DO and salinity were more stable, eutrophication indicators included Noctiluca spp., copepods (Acartia, Oithona), V. alginolyticus, and Photobacterium damselae. These findings indicate that estuaries act as pollution hotspots while marine waters are also affected, emphasizing the need for ecosystem-based management of shrimp aquaculture effluents.

Abstract

This study aims to analyze the physicochemical characteristics and microbiota communities in the Paya Nie Ecotourism Reservoir as a basis for water quality management for sustainable fisheries cultivation. Sampling was conducted at ten points representing the western, central, and eastern parts of the reservoir. Parameters measured included temperature, clarity, turbidity, pH, salinity, dissolved oxygen (DO), ammonia, phosphate, nitrate, COD, BOD, plankton density, and Escherichia coli. The results showed that most parameters were still in accordance with quality standards (PP No. 22 of 2021), especially pH (7.03–7.97), ammonia (0.001–0.028 mg/L), phosphate (2.6–3.9 mg/L), and nitrate (0.02–2.0 mg/L). However, DO levels at several stations were low (1.67–3.33 mg/L), while COD (500–926 mg/L) and BOD (1.00–2.47 mg/L) exceeded the threshold, indicating a high organic pollution load. The highest E. coli value was recorded at Station X (744.33 CFU/100 ml), indicating contamination from domestic activities. The dominant plankton species were Euglena sp. and Eudorina sp., indicating the waters are classified as productive but potentially eutrophic. The results of this study emphasize the need for waste management, cage density regulation, and routine water quality monitoring to maintain ecosystem balance and support the sustainability of fish farming in the Paya Nie Reservoir.

Abstract

This study aims to analyze the influence of fuel prices (BBM) and sea wave height on the price of mackarel tuna in Banda Aceh City, with a case study at the Ocean Fisheries Port (PPS) Kutaraja Lampulo. The study uses monthly secondary data from 2019 to 2024 and applies a Linear Regression Model for analysis. The regression results indicate that both fuel prices and sea wave height have a significant effect on mackarel tuna prices at the 0.05 significance level. The wave height variable shows a positive coefficient, indicating that higher waves tend to increase mackarel tuna prices. This finding is consistent with the theory that extreme sea conditions hinder fishing activities, reduce fish supply, and consequently increase prices. However, the fuel price variable shows a negative coefficient, contrary to the economic theory that rising fuel prices should increase commodity prices due to higher production costs. This result is likely due to the stability of fuel prices (diesel fuel) during the observation period and the operational efficiency achieved through the use of technology by fishermen, allowing them to maintain or even improve catch volumes despite rising fuel prices.

Abstract

This study aimed to determine the presence of AMD, analyze mangrove structure, and determine the relationship between AMD and mangrove density. AMD and mangrove stands were collected using a 40 meter transect line parallel to the shoreline, and four 10 x 10 m plots were created. One-way ANOVA statistics were used to test the mean differences in SLA telling, while the Shapiro-Wilk test and Spearman correlation were performed to analyze the relationship between SLA telling and mangrove structure. A total of 11923 AMD items were found in the Cut Mamplam mangrove ecosystem, with a density ranging from 47075 to 76900 items/ha. Furthermore, four species of mangrove trees were found in the mangrove stands, with Avicennia alba having the highest tree, sapling, and seedling densities (3275 ± 5158 ind/ha, 2800 ± 1932.18 ind/ha, and 132500 ± 75883.68 ind/ha). The relationship between AMD and mangrove density was not very strong, with no significant associations between adults, saplings, or seedlings (p > 0.05) on the amount of AMD retained in the Cut Mamplam mangrove ecosystem. This study is an initial step in assessing the impact of AMD on mangrove vegetation and sustainable monitoring, leading to the initiation of public awareness and future strategies for improved coastal and marine monitoring and management.

Abstract

This study aimed to identify the concentration of heavy metals, lead (Pb) and cadmium (Cd), in sediments and oysters (Bivalvia), as well as to examine their relationship with mangrove ecosystem characteristics in Kuala Ceurape (Bireuen) and Udeung Village (Pidie Jaya). Heavy metal concentrations were analyzed using the Indonesian National Standard (SNI) methods, while mangrove species identification was conducted through field vegetation surveys. The results showed that Pb concentrations in sediments ranged from 3.67–15.29 mg/kg with an average of 7.38 mg/kg in Udeung and 8.65 mg/kg in Kuala Ceurape. Cd concentrations in sediments were higher, ranging from 4.69–11.95 mg/kg (average 7.38 mg/kg) in Udeung and 3.54–11.69 mg/kg (average 8.65 mg/kg) in Kuala Ceurape. In oysters, Pb concentrations were recorded at 4.36–9.53 mg/kg in Udeung and 2.16–6.71 mg/kg in Kuala Ceurape, while Cd showed greater accumulation, reaching 17.07–18.13 mg/kg (average 12.71 mg/kg) in Udeung and 1.96–11.21 mg/kg (average 5.16 mg/kg) in Kuala Ceurape. Compared to FAO/WHO and CCME standards, Pb levels in sediments remained below the threshold, but Pb and Cd in oysters and Cd in sediments exceeded safe limits. Vegetation identification indicated the dominance of Rhizophora apiculata, which plays an important role in heavy metal trapping. These findings suggest that mangrove ecosystems function as natural filters of heavy metals, yet bioaccumulation in edible biota such as oysters may pose potential health risks to coastal communities.

Abstract

The banggai cardinalfish (Pterapogon kauderni) is an endemic fish species in the Banggai waters of Central Sulawesi, with an attractive body shape, making it a prime target for ornamental fish hobbyists. One of the causes of the decline in the Banggai cardinalfish population is disease infection. This study aims to identify pathogenic bacteria that infect the Banggai cardinalfish and to determine their pathogenicity levels. The research was conducted in two stages: first, isolation and identification of bacteria from the Banggai cardinalfish, and second, pathogenicity tests of the identified bacteria. Four bacterial isolates were obtained from the Banggai cardinalfish, and based on morphological characteristics and biochemical tests, four bacterial types were identified according to Bergey’s Manual of Determinative Bacteriology, namely Microbacterium spp., Rhodococcus spp., Bacillus sp., and Edwardsiella spp. The bacterium with the highest pathogenicity toward the Banggai cardinalfish was Bacillus sp., followed by Edwardsiella spp., Microbacterium spp., and Rhodococcus spp. Based on these results, it can be concluded that the identified bacteria are capable of killing the Banggai cardinalfish.
