Abstract

This study aimed to determine the extract of concentration of white turmeric powder in inhibiting the growth of the fungus A. flavus and to determine of active substances contained in the white turmeric powder. The parameters bioactive compounds observed total phenol contains, total flavonoids contains, and curcumin contains. White turmeric powder was extracted using 96% ethanol. The extraction method used is maceration. This study used a Completely Randomized Design with several concentrations of concentrated extract of white turmeric powder consisting of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%.
