Abstract

Rhizophora mucronata is a type of mangrove plant that acts as a natural antioxidant which is used as a food ingredient and traditional medicine. The aim of this research was to determine the profile of secondary metabolites, antioxidant activity and total phenols of R. mucronata leaf extract. R. mucronata leaves were obtained from Gunung Anyar District, Surabaya City and then extracted using three solvents with different polarities, namely n-hexane, ethyl acetate, and ethanol. Mangrove leaf extract (Rhizopora mucronata) was followed by phytochemical testing using color testing, antioxidant activity testing using the DPPH method, and determining phenol content using the Folin-Ciocalteu method. Phytochemical tests show that all R. mucronata mangrove leaf extracts contain secondary metabolites such as flavonoids, saponins, steroids, triterpenoids and tannins with total phenols ranging from 0.04%-6.7%. The antioxidant activity of n-hexane, ethyl acetate, and ethanol extracts were 4.9 mg ± 0.82%, 1.7 mg ± 0.17%, and 0.21 mg ± 1.9%, respectively.

Abstract

The seagrass ecosystem of Pari Island, Kepulauan Seribu National Park, provides essential habitat for various fish resources, such as Sphaeramia orbicularis. Little information has been reported on the biology and ecology of this species in Indonesia. This study describes the growth pattern, feeding ecology, and reproductive biology of S. orbicularis in the seagrass beds of Pari Island. Fish samples were collected monthly from November 2023 to April 2024 using a beach seine net. A total of 542 fish were obtained with a range of 17-85 mm and weights of 0.16-24.28 g. Fish growth patterns were isometric and positive allometric with condition factor values >1. Based on feeding ecology, S. orbicularis is categorized as a specialist and has a low niche breadth (BA=0.2), with the primary diet being Gammaridae, Tanaidacea, and Brachyura. The fish population has a balanced sex ratio and spawns in January. This is indicated by the highest GMS mature gonad and GSI values found in that month. Egg fecundity ranged from 7,239-12,240 eggs with an average diameter of 0.0048-0.0052 mm, indicating a total spawner spawning pattern. The length of the first gonad maturity of male fish was 63.12 mm, while that of female fish was 65.27 mm.

Abstract

Fresh fish are highly perishable due to their high moisture content, requiring proper handling to extend their shelf life. Edible coatings using fish-derived gelatin offer a halal and eco-friendly alternative. This study aimed to enhance the antioxidant and antibacterial activities of patin fish skin gelatin by combining it with carrageenan and red ginger essential oils. This study involved gelatin and edible coating production, followed by testing for antioxidant and antibacterial activities against S. aureus and E. coli. Formula optimization was performed using Response Surface Methodology (RSM) via Design Expert V12, with the results verified through a Paired T-Test in Minitab 19. The addition of carrageenan and red ginger essential oils significantly affected the inhibition percentage and antibacterial activity. The optimal formula included 0.5 g carrageenan and 1.5 mL red ginger essential oil. The verification steps showed alignment with predictions for Staphylococcus aureus but not for Escherichia coli.

Abstract

Central Kalimantan has a large area of peatland that contains a lot of peat water, which can be used as a source of clean water and drinking water. Meanwhile, the community still lacks clean water because peat waters are acidic to highly acidic, corrosive, and reddish-black, making them unsuitable for human use.  Therefore, efforts are needed to purify peat water to be suitable for human consumption.  This study aimed to assess the effectiveness of using calcium carbonate lime, alum, and activated carbon to purify peat water.  This research was divided into 2 stages, namely preliminary research by testing the combination of the three materials mentioned above with the dose of each material, 0.3 g/L, 0.6 g, and 0.9 g/L, so that 33 treatments were obtained, namely 27 treatments.  Test parameters in preliminary research are pH, water colour, and water appearance.  In the main research, the observed variables were pH, water colour, TDS, and the appearance of water.  In the main study, the best 6 treatments from the preliminary study were used, where the pH value was close to normal, ranging from 5.76 to 6.16, and the colour value ranged from 4 to 15 Pt-Co, and there was no foam. The best 3 main research results carried out complete testing of physical, chemical and microbiological water quality parameters for clean water, namely physical parameters (colour, odour, taste, turbidity, temperature, and TDS), chemistry (organic matter, pH, hardness, iron, manganese, sulphate, nitrite, chloride, nitrate, zinc, cyanide, fluoride, ammonia, aluminium and copper), and microbiology (total coliform and E. coli). Based on the results obtained, in the main study, the use of a combination of calcium carbonate lime, alum, and activated carbon at doses of 0.3 g/L, 0.3 g, and 0.6 g/L respectively was very effective in purifying peat water into water suitable for human consumption, so these doses are recommended for purifying peat water.

Abstract

Tawes fish has economic value and affordable price. Growth rate and survival rate are important factors in cultivation productivity. The purpose of this study was to test the effectiveness of recombinant growth hormone of kertang grouper (rElGH) on the growth response of tawes fish seeds at different stocking densities. This study used a factorial randomized design with two treatment factors and three replications. The treatments were rElGH (dose 0 mg/kg and 2 mg/kg) and different stocking densities (40 fish/m3, 80 fish/m3 and 160 fish/m3). The tawes fish seeds used weighed 2.33 ± 0.002 cm and were 4-5 cm long. Maintenance is carried out for 60 days used a hapa measuring 1.0 × 1.0 × 1.0 m3 with a water height of ±60 cm.  Fish are fed with at satiation method using commercial feed with a protein content of 31-33%. The administration of rElGH was carried out on the first 7 days of maintenance and continued with the provision of feed without rElGH. The results of the Two-way ANOVA analysis showed that the use of rElGH and stocking density and their interactions had significant differences. The best treatment was the provision of rElGH stocking density 40 (R40) with survival rate 100%, specific growth rate 3.58%/day, absolute weight gain 8.75 g, and feed conversion ratio 1.12. The combination of the use of rElGH and increasing stocking density significantly increased the biomass production of tawes fish.

Abstract

Acne patch preparation is an acne medication that is used topically. Sea grape (Caulerpa racemosa) has the potential to contain antibacterial substances that can be applied to acne patch preparations to suppress the growth of acne-causing bacteria Propionibacterium acnes. The objective of this research is determining the potential of Caulerpa racemosa antibacterial substances applied to acne patch preparations in suppressing the growth of bacteria that cause Propionibacterium acnes acne. The treatment used was the addition of different Caulerpa racemosa extracts (0%, 15%, 20%, and 25%). Parameters observed were pH, antibacterial, irritation, thickness, hedonic, moisture absorption, water absorption, and adhesion. The analysis showed that adding Caulerpa racemosa extract had a significant effect (P<0.05) on antibacterial activity. The addition of extract with a concentration of 25% is the best treatment compared to other treatments, with an antibacterial activity value of 5.25 ± 0.35 mm with a weak inhibition zone category, pH 5.92±0.04, non-irritating, thickness 0.54±0.02 mm, hedonic getting somewhat like value (appearance, aroma, and texture), moisture absorption 4.47±0.03%, water absorption 1.16±0.02%, and adhesion 231.24±0.08 seconds.

Abstract

The length-weight relationship and condition factor of Coptodon zillii from three different waterbodies (Aiba Reservoir, Asejire Reservoir, and Igbokoda River) in Southwest Nigeria were analyzed to determine the species' growth pattern and overall well-being. A total of 150 fish samples were collected from the landings of commercial fishermen. The length-weight relationship and condition factor (K) of the fish samples were determined following standard techniques. The study found that the three C. zillii populations exhibited negative allometric growth, with regression coefficients (b) values less than 3. This indicated that the fish's length increased at a faster rate than their weight. The condition factor (K) ranged from 1.92 to 2.03, suggesting that the fishes were in good health in their respective habitats. The variations in the mean condition factor values across the three populations suggested that the environmental conditions in the water bodies uniquely impacted the health and growth of the fish. These findings highlight the need for targeted fisheries management strategies to improve the sustainability of C. zillii populations in these aquatic systems.

Abstract

Cholesterol is a significant contributor to mortality rates worldwide. The quest for effective cholesterol treatments continues, aiming to develop preventive agents with minimal adverse effects. This study seeks to elucidate the anti-cholesterol properties of extracts and components fractionated from water chestnut (Eleocharis dulcis). The research encompassed several phases, including sampling, extraction and fractionation, qualitative and quantitative flavonoid analysis, anti-cholesterol activity assays, and gas chromatography-mass spectrometry (GC-MS) analysis. The quantitative flavonoid assessment revealed that the highest flavonoid concentration was present in the ethyl acetate:methanol (5:5) fraction, totaling 79.224 mg/mL. The water chestnut extract demonstrated notable anti-cholesterol activity with an IC50 value of 13016.27 ± 5648.31 ppm, whereas the water chestnut fraction exhibited enhanced anti-cholesterol activity with an IC50 value of 42.22 ± 9.79 ppm, comparable to simvastatin. The bioactive compounds in water chestnut attributed to its anti-cholesterol effects include 7,9-Di-tert-butyl-1-oxaspiro(4,5)deca-6,9-diene-2,8-dione, n-Hexadecanoic acid, Octadecanoic acid ethyl ester, 9-Octadecenamide (Z)-, 9,12,15-Octadecatrienoic acid, 2,3-dihydroxypropyl ester, 3,4-Dimethoxycinnamic acid, and 2H-1-Benzopyran-2-one, 7-methoxy-. These findings suggest that the fraction derived from E. dulcis exhibits significant anti-cholesterol activity and holds promise for further development in the treatment of hypercholesterolemia.

Abstract

This study investigates the accumulation of heavy metals cadmium (Cd), copper (Cu), chromium (Cr), and lead (Pb) in the water, sediment, and body parts of whiteleg shrimp (Litopenaeus vannamei) cultured in traditional aquaculture ponds in Sidoarjo, Indonesia. The ICP-AES method showed that heavy metals were more concentrated in sediment than in water, particularly Pb and Cd. Cd levels in water and Pb levels in sediment exceeded national and international quality standards. In shrimp tissue, the highest accumulation occurred in the cephalothorax, especially for Cu, although all detected levels remained within the safety limits set by Indonesian standards. Monitoring heavy metals in the aquaculture environment and shrimp is essential, as these contaminants can bioaccumulate and pose health risks to aquatic organisms and humans throughout the food chain. Water quality parameters were generally suitable for shrimp farming, but low pH values may increase heavy metal solubility and bioaccumulation risks. These findings highlight the need for regular monitoring and better environmental management to ensure the sustainability and safety of traditional shrimp aquaculture systems.

Abstract

Coleus blumei (miana) can be used as an antimicrobial, antibacterial, antioxidant, and anti-inflammatory. Research on miana leaf extract in feed to increase the immune response of whiteleg shrimp has not been found. This study aims to analyze miana leaf extract in feed on the immune response of whiteleg shrimp. The study was conducted in July 2023 at the Hasanuddin University Laboratory and the Bogor Agricultural Institute Laboratory. The method used was a completely randomized design, 4 treatments and 3 replications, extracts of 0 g, 1 g, 2.5 g, and 7.5 g/kg of feed. The statistical results of the treatment gave a significant effect (p<0.05) on total hemocytes and phenoloxidase activity but did not give a significant effect (p>0.05) on the survival of whiteleg shrimp. The extract of 7.5 g/kg of feed had the highest impact on total hemocytes 8.43x103 cells/mm3, phenoloxidase activity 0.222 optical density ƛ=490, and 100% survival. The extract of 0 g/kg feed had the lowest impact on total hemocytes, 2.37x103 cells/mm3, phenoloxidase activity of 0.09 Optical Density ƛ=490, and survival of 90%. Conclusion, Coleus blumei leaf extract in feed can improve the immune response and survival of whiteleg shrimp. The recommended concentration in aquaculture is 7.5 g/kg.
