In Vitro Phytochemical And Antibacterial Activity Test On Temu Putih Extract Curcuma Zedoaria Against Aeromonas Hydrophila

Aeromonas hydrophila bacterium is one of the bacteria which frequently attack fresh water aquaculture and cause the farmer experience terrible loss. In order to cope with the diseases caused by A. hydrophila bacteria the usage of natural antibacteria was more recommended as it does not give negative effects to the environment. One natural antibacteria which can be used against A. hydrophila is from the white turmeric extract Curcuma zedoaria. The aim of this study is to know the active compound content in white turmeric Curcuma zedoaria to determine the most effective solvent and the effective maceration duration to extract Curcuma zedoaria as antibacteria against Aeromonas hydrophila using disc diffusion method. The study used descriptive and experimental method with treatments to 3 different solvents ethanol ethyl acetate and chloroform and 3 repetitions. The data acquired from the results of the study were then analyzed descriptively. Results showed that Curcuma zedoaria extract from the phytochemical test contained saponins alkaloid and flavonoid. The best solvent was ethyl acetate with maceration for 2x24 hours and inhibition area width 11.34 mm.
