Abstract

Snakehead fish (Channa striata) is a freshwater fish that can be found throughout Indonesian waters. Snakehead fish in today's society has been associated with medicine. Snakehead fish is processed into various types of dishes and then served to sick families, especially for those who are postoperative because its content has been clinically proven in several diseases. Snakehead fish has a high protein content, especially albumin and essential amino acids, fat, especially essential fatty acids, minerals, especially zinc (Zn), and several vitamins that are very good for health. Bioactive compounds that play a role in accelerating the wound healing process are albumin, glycine, and zinc (Zn). Wound healing is highly dependent on the biochemical processes that occur in the skin involving intrinsic and extrinsic factors. This healing process will be accelerated with the help of dried extracts of Snakehead fish designed in topical forms such as creams or gels

Abstract

Mangrove ecosystems play a critical role as blue carbon sinks, yet quantitative data on carbon stocks in many coastal villages of Jambi Province remain scarce. This study estimated above- and belowground biomass and carbon stocks in the mangrove ecosystem of Pangkal Babu Village, Tungkal Ilir District, Tanjung Jabung Barat Regency, Jambi Province, Indonesia. A non-destructive inventory method was employed across three stations, with a total of eighteen 10 × 10 m sample plots. Tree diameter at breast height (DBH) was measured for all individuals with DBH ≥ 4 cm, and biomass was computed using the generic allometric equation of Komiyama et al. (2005). Six mangrove species were recorded: Sonneratia alba, Avicennia alba, A.marina, Rhizophora apiculata, R. mucronata, and Bruguiera gymnorrhiza, with a total of 246 individual trees. Mean total biomass was 189.29 ± 69.91 Mg/ha and mean carbon stock was 88.96 ± 32.88 Mg C/ha, equivalent to 326.50 ± 120.70 Mg CO₂e/ha. Station 2 exhibited the highest carbon stock (127.88 Mg C/ha), dominated by Avicennia alba with the highest importance value index (IVI = 97.65). These results confirm that the mangrove ecosystem of Pangkal Babu Village serves as a substantial carbon reservoir and should be prioritized for conservation and rehabilitation programs

Abstract

The province of Riau has many freshwater bodies that play a very important role in the lives of those around them. This study aimed to determine the relationship between chlorophyll a and Total-P (Total Phosphorus) concentrations and to assess the trophic status of Perupuk Lake in Perhentian Raja Sub-District, Kampar Regency, Riau Province. The research was conducted from October to December 2024 at three stations: Station 1 (inlet, no settlement), Station 2 (lake main basin with fish cages), and Station 3 (outlet with settlement and agricultural activity). Sampling was performed 5 times at 1-week intervals at the surface and at 2 Secchi depths. Parameters measured included chlorophyll a, Total-P, temperature, transparency (Secchi depth), pH, dissolved oxygen (DO), free carbon dioxide (CO2), and nitrate. Results showed that chlorophyll a concentration ranged from 11.04 to 14.14 µg/L, with the highest at Station 2 (14.14 µg/L) and the lowest at Station 1 (11.04 µg/L). Total-P concentrations ranged from 0.0168–0.0338 mg/L, following the same pattern: highest at Station 3 (0.0338 mg/L) and lowest at Station 1 (0.0168 mg/L). Simple regression analysis showed a non-significant relationship between Total-P and chlorophyll-a (R² = 0.0266–0.0774), indicating that, in mesotrophic waters, other factors, such as light and nitrogen availability, also influence chlorophyll-a concentration. Based on chlorophyll a and Total-P concentrations, Perupuk Lake is categorized as a mesotrophic water body, with supporting parameters within optimal ranges for aquatic organisms.

Abstract

Liquid organic fertilizer (LOF) derived from the solid waste of catfish processing is a fermented organic product containing macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), as well as micronutrients, amino acids, and decomposer microorganisms that improve water quality. This study aims to analyze the effects of LOF application on peat water quality and the growth performance of climbing perch (Anabas testudineus), and to determine the optimal dosage for cultivation. The research was conducted from June to July 2025 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau, with fish rearing carried out in the hatchery using aquarium. The study employed a Completely Randomized Design (CRD) consisting of five treatments: P0 (0 ml/L), P1 (1.5 ml/L), P2 (2 ml/L), P3 (2.5 ml/L), and P4 (3 ml/L), each with three replications. The results showed that water quality parameters remained within acceptable ranges, with temperature of 28.73–28.9°C, pH of 4.96–5.2, TDS of 108.26–124.6 ppm, transparency of 7.66–9.1 cm, DO of 5.23–5.36 mg/L, alkalinity of 17–28 mg/L, nitrate of 4.0045–8.7292 mg/L, and orthophosphate of 1.5397–3.5454 mg/L. The application of POC increased pH, TDS, nitrate, and orthophosphate concentrations. The best growth performance was observed in treatment P2 (2 ml/L), which produced the highest absolute weight gain (2.15 g) and absolute length growth (2.72 cm), while the survival rate reached 100% across all treatments. Therefore, the P2 dosage is considered the most effective treatment for improving peat water quality and enhancing the growth of climbing perch.

Abstract

Peatland waters hold great potential for aquaculture development; however, their unfavorable characteristics, such as low pH, brownish water color, and high levels of Total Dissolved Solids (TDS) and Total Suspended Solids (TSS), pose major challenges. One approach to improving peat water quality is the use of aquatic plants as phytoremediation agents, such as Lemna sp. This study aims to determine the effect of Lemna sp biomass on the physical parameters of peat water and to identify the optimal biomass for the rearing of Asian redtail catfish (Hemibagrus nemurus). The study was conducted from March to July 2025 at the Integrated Marine Science Laboratory of the Faculty of Fisheries and Marine Sciences at the Universitas Riau. The research method used was an experiment with a one-factor completely randomized design (CRD), consisting of five Lemna sp biomass treatments (0, 25, 37.5, 50, and 62.5 g/m²) and three replicates. The parameters observed included TDS, TSS, turbidity, temperature, pH, water color, absolute weight gain, and survival rate of Asian redtail catfish. The results showed that the addition of Lemna sp biomass significantly improved (P<0.05) the physical parameters of peat water. Increasing the Lemna sp biomass reduced TDS and TSS values and improved water clarity compared to the control without Lemna sp. These improvements in water quality positively affected the absolute weight gain and survival rate of Asian redtail catfish during the rearing period. A Lemna sp. biomass of 62.5 g/m² yielded the best results, with the most optimal physical quality of peat water and the highest growth and survival rates of Asian redtail catfish.

Abstract

Carotenoids are natural pigments with significant potential that are widely synthesized by photosynthetic bacteria. In addition to playing a role in photosynthesis, carotenoids also function as natural antioxidants capable of inhibiting the formation of free radicals and providing protection against oxidative stress. This study aims to characterize and to identify carotenoid pigments synthesized by marine photosynthetic bacteria, to determine the types of pigments, as well as to prove their antioxidant activity. The method used in this study was experimental, conducted to test the ability of marine photosynthetic bacteria to synthesize carotenoid pigments as producers of antioxidant compounds. The results of the study indicate that isolate LD07, a photosynthetic marine bacterium, contains carotenoid pigments. UV-Vis spectrophotometer analysis revealed a maximum absorption peak at a wavelength of 490 nm, a value within the characteristic absorption region of carotenoid pigments
