This research aimed to determine the inhibited effect of Aloe (Aloe barbadensis Miller) rind extract to the growthof bacteria Staphylococcus aureus and Escherichia coli and the most effective concentration for the resistanceagainst both of bacteria tested. The results showed that the extracts of Aloe rind inhibited the growth of bacteriaStaphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922. It was indicated by the formation ofinhibition zones with the largest diameter average occurred concentrations of 100% with the size 11,58 mm forthe Staphylococcus aureus and 6,81 mm in Escherichia coli. The highest concentration inhibited the growth ofStaphylococcus aureus ATCC 25923 was 100% and 75% for the Escherichia coli ATCC 25922.
