Taro is a plant with widely consumed tubers by the Indonesian people. In addition to tubers, used as food, taro leaves can be used as an alternative drug for their antibacterial properties. The content of secondary metabolites within the taro leaves is able to inhibit the growth of pathogenic bacteria Escherichia coli and Bacillus cereus. The method used in this research is by using taro leaf extract which is divided into various concentration variations. Taro leaf extract using ethanol solvent 96%. The results showed that each concentration showed an antibacterial ability in inhibiting the growth of pathogenic bacteria. The best concentration in inhibiting bacterial growth is 50mg / ml. The higher concentration of taro leaf extract is used, the greater the ability to inhibit the growth of bacteria.
