Abstract

Abstract Vibriosis is a major problem in aquaculture that causes large numbers and rapid mortality of fish. Vibriosis treatment is still limited to the same antibiotics in humans and animals. This study aims to obtain bacterial isolates from termite nests that are antivibrio and determine the profile of the antivibrio bioactive compounds. Bacterial isolates were obtained from three types of termite nests. All isolates were cultured on ISP media and then characterized and conducted bioassay tests against Vibrio alginolyticus and Vibrio harveyi. Secondary metabolite fermentation products from selected bacterial isolates were extracted using ethyl acetate and detection of bioactive compounds by Thin Layer Chromatography (TLC) method. The isolation results obtained 15 isolates, 10 Gram-positive bacteria namely isolates SR1, SR2, SR8, SR9, RE2, RE3, RE5, SE1, SE4, SE6 while the other 5 isolates are Gram-negative bacteria. Antivibrio screening obtained 7 isolates that have antivibrio activity. The strongest antivibrio activity is SE1, which was able to inhibit the growth of V. alginolyticus bacteria with an inhibition zone of 3.5 cm and V. harveyi with an inhibition zone value of 4 cm and was also positive for catalase.  TLC showed that SE1 contained peptide compounds with purple color changes after dyeing using ninhydrin.

Abstract

The poultry farming industry is part of the growing agro-complex sector and is essential in providing animal protein to support national food security. The productivity and safety of the food produced are still challenging in cultivation activities. The Socialization of Poultry Farming Management and Training on Making Independent Synbiotic Feed based on ODB bacteria from PT Pertamina Patra Niaga AFT Hasanuddin oil Cather is a community empowerment activity that has an impact on the beneficiary community, namely the Lelang Kassie farmer women's group and the Baji Mangai Village community, Maros Regency. This activity includes socialization, training, and application of technology in duck farming activities. Increased knowledge and skills of the community can independently produce ODB bacterial starter, which is then used in synbiotic feed and applied to poultry. This has an impact on the potential for increasing community income, and this innovation can encourage an increase in duck production with the quality of meat and eggs produced safe from chemical residues.

Abstract. Dahlia, Ardiansyah, Amrullah, Khatimah K, Dwinhoven I, Mega DAU. 2025. Red dragon fruit peel as a natural pigment enhancer in goldfish (Carassius auratus). Asian J Agric 9: 777-786. Color quality enhancement is an important factor in the ornamental fish industry, particularly for goldfish (Carassius auratus), as it directly affects market value and consumer preference. The use of carotenoid-based feed additives offers a sustainable alternative for improving the visual appearance of fish. Red dragon fruit (Hylocereus polyrhizus) peel, which is generally discarded as agro-industrial waste, is known to contain natural carotenoids, particularly betacyanin and beta-carotene, which have potential applications in aquaculture. This study aimed to evaluate the effectiveness of Red Dragon Fruit Peel Extract (RDFPE) in improving the color brightness of goldfish, along with related physiological parameters. A completely randomized design was used, consisting of five RDFPE dosage treatments (0, 50, 100, 150, and 200 mL/kg of feed), each with three replicates. The measured parameters included color brightness level, total carotenoid concentration, chromatophore cell count, growth, survival rate, and water quality. The results showed that RDFPE had a significant effect (p<0.05) on color brightness level, with the optimum response observed at 150 mL/kg, followed by a decline at higher dosages. In contrast, RDFPE had no significant effect (p>0.05) on growth or survival rate. Total carotenoid concentration and chromatophore cell count were reported descriptively (mean ± SD) without statistical analysis, indicating that differences among treatments for these parameters require further confirmation. Water quality remained within the optimal range. These findings highlight the potential of RDFPE as a natural and eco-friendly feed additive for enhancing ornamental fish coloration while promoting the sustainable utilization of agro-industrial waste.
