Abstract

Karakteristik kombucha terbagi menjadi karakteristik kimiawi dan biologi. Kombucha merupakan minuman fermentasi yang kaya akan kandungan antioksidan. Mentimun dipercaya bermanfaat sebagai sumber antioksidan yang dapat mencegah radikal bebas. Penelitian tentang aktivitas antioksidan kombucha dengan berbagai substrat sudah banyak dilakukan, tetapi penelitian tentang aktivitas antioksidan kombucha mesokarp mentimun (Cucumis sativus L.) belum pernah dilakukan. Oleh karena itu, penelitian ini dilakukan untuk mengetahui karakteristik serta aktivitas antioksidan kombucha mesokarp mentimun pada hari ke-6 dan 12. Fermentasi dilakukan selama 6 dan 12 hari, kemudian masing-masing sampel diuji karakteristiknya, seperti pH, berat kering scoby (Symbiotic Culture of Bacteria and Yeast), kadar gula pereduksi, serta total asam. Aktivitas antioksidan kombucha mesokarp mentimun diuji melalui metode DPPH, kemudian dihitung nilai IC50 nya. Hasil menunjukkan pH dan kadar gula pereduksi mengalami penurunan, sedangkan berat kering scoby dan total asam mengalami peningkatan. Aktivitas antioksidan kombucha mesokarp mentimun menunjukkan nilai IC50 hari ke-6 sebesar 3,5 ppm dan hari ke-12 sebesar 4,4 ppm. Kombucha mesokarp mentimun memiliki antioksidan sangat kuat yang dapat dimanfaatkan sebagai pengobatan alternatif.

Abstract

Fragaria x ananassa or strawberry has significant economic value worldwide. However, its cultivation faces various challenges. One example was fungal diseases, such as anthracnose, caused by Colletotrichum acutatum. Disease management generally relies heavily on synthetic fungicides, raising concerns about environmental sustainability and human health risks. Therefore, more environmentally friendly alternatives are needed, such as the use of biological agents. This study aims to assess the potential of endophytic fungi from strawberry plants as natural biocontrol agents against Colletotrichum acutatum. The study began with the isolation of endophytic fungi from strawberry tissues and their characterization morphologically. The antagonistic activity of endophytic fungi against colletotrichum acutatum was evaluated using three methods: a dual culture assay to assess direct inhibition, a cell-free filtrate assay to analyze the effect of fungal metabolites, and a volatile organic compound (VOC) assay to inhibit the growth of pathogenic pathogens. In this study, 20 fungal isolates were successfully isolated. A total of 15 showed antagonism against Colletotrichum acutatum. Isolate A1 showed potent inhibition in the dual culture test by effectively antagonizing Colletotrichum acutatum. Isolate D1 produced extracellular compounds that reduced the growth of Colletotrichum acutatum by 52.28% ± 3.21% in the cell-free filtrate assay. At the same time, isolate D3 proved most effective in the VOC assay, suppressing the growth of pathogenic colonies by 71.35% ± 3.37%. Thus, endophytic fungi, especially isolates A1, D1, and D3, have the potential to serve as an environmentally friendly alternative to combat anthracnose disease on strawberries.

Abstract

Aeromonas hydrophila bacteria can cause Motile Aeromonas Septicemia (MAS), a disease that impacts freshwater fish. The turmeric rhizome contains numerous bioactive compounds that act as antibacterials and might be utilized to inhibit A. hydrophila. This research aimed to identify the phytochemicals in turmeric (Curcuma domestica) infusion, evaluate its antibacterial activity against A. hydrophila, and define the toxicity effect of turmeric rhizome infusion. The agar dilution method was used to measure antibacterial activity, whereas the Brine Shrimp Lethality Test (BSLT) was used to assess toxicity. The research confirmed the presence of phytochemicals such as tannins, alkaloids, flavonoids, phenols, and saponins in a turmeric rhizome infusion. According to the findings, the infusion from turmeric rhizome effectively inhibited the growth of A. hydrophila at concentrations between 750-1000 ppm. In toxicity tests, the LC50 value of the turmeric rhizome infusion against shrimp larvae was 381.18 ppm. Hence, the turmeric rhizome infusion has the potential to be further developed for the prevention and treatment of fish infected with A. hydrophila in freshwater fish farming.

Abstract

Aeromonas hydrophila is an infectious agent that triggers Motile Aeromonas Septicemia (MAS) in freshwater fish, including catfish, leading to significant economic losses in aquaculture. This study aims to evaluate the antibacterial activity of Mango Bacang (Mangifera foetida L.) leaf infusion against A. hydrophila and its effect on catfish mortality. The research methods included the preparation of the infusion, phytochemical screening, antibacterial activity testing, and assessing the infusion's impact on catfish mortality. Phytochemical screening revealed that Mango Bacang leaf infusion contains alkaloids, flavonoids, phenols, tannins, and saponins, contributing to its antibacterial properties. The well-diffusion technique used to examine antibacterial effects demonstrated that the infusion at concentrations of 5–100% produced significant inhibition zones against A. hydrophila, with strong activity observed at a 5% concentration (14.38 ± 1.67 mm). However, toxicity testing on catfish indicated increased mortality with higher infusion concentrations, reaching 50% at 5% concentration. These findings suggest that Mango Bacang leaf infusion has potential as a natural antibacterial agent to control A. hydrophila, but its use requires precise dosage management to ensure safety for catfish. Further studies are necessary to optimize effective and environmentally friendly concentrations and explore applications on a broader scale.
