Antibacterial activity of ethanol extract of banana, cassava, and pineapple peels against a fish pathogen Aeromonas hydrophila

Abstract. Mulia DS, Raicha R, Lunggani CP, Erina SN, Wuliandari JR, Purbomartono C, Isnansetyo A. 2023. Antibacterial activity of ethanol extract banana, cassava, and pineapple peels against a fish pathogen Aeromonas hydrophila. Biodiversitas 24: 481-485. hydrophila is the most virulent bacteria for almost all freshwater species. One method to control pathogenic in should be safe environmentally friendly, including utilizing natural wastes such as banana (Musa paradisiaca), cassava (Manihot esculenta), (Ananas comosus). These contain bioactive compounds. Their utilization increases waste value. This study aims determine potential peel, peel an antibacterial hydrophila, causing agent Motile Septicemia (MAS) fish. Parameters observed included phytochemical compounds, MIC, MBC values peels. Phytochemical screening was performed using thin-layer chromatography (TLC) foam test. The microdilution carried out It determines minimum inhibitory concentration (MIC); bactericidal (MBC) values. results showed that extracts contained flavonoids, alkaloids, terpenoids, tannins, saponins. MIC were 600, 400, 200 µg/mL, respectively. 4 × 2 1 Extract exhibited better than However, three indicated developed bactericides bacterial disease.
