Uji Plagiasi : ANTIBACTERIAL POTENTIAL OF BANGKAL LEAVES (NAUCLEA SUBDITA (KORTH.) STEUD.) METHANOL EXTRACT AGAINST AEROMONAS HYDROPHILA

Abstract

The content of bioactive compounds in the leaves of the bangkal plant (Nauclea subdita (Korth.) Steud.) such as flavonoids and phenols can cause this bangkal plant to work as an antibacterial. The potential of bangkal leaf extract as a therapeutic agent in treating bacterial infections in fish, as well as providing a new direction in developing a more effective and sustainable management strategy for Aeromonas Hydrophila disease. The research aims to analyze the antibacterial potential of methanol extract of bangkal leaves (Nauclea subdita (Korth.) Steud. ) against Aeromonas Hydrophila. The research was carried out at the Basic Laboratory of the Faculty of Fisheries and Maritime Affairs, Bagkal leaf extraction activities at the Mathematics and Natural Sciences Laboratory at Lambung Mangkurat University, Banjarbaru. The type of active compound contained in the methanol extract of bangkal leaves (Nauclea subdita (Korth.) Steud.) which has antibacterial properties against Aeromonas Hydrophila bacteria is that the methanol extract from bangkal leaves has the potential as an antibacterial agent against Aeromonas Hydrophila bacteria. Phytochemical analysis found the presence of alkaloids, flavonoids, tannins and saponins in the extract. Inhibitory power tests using the disk method and Minimum Inhibitory Concentration (MIC) test as well as the coculture method showed that the concentration of the extract significantly influenced its ability to inhibit bacterial growth.
