Abstract

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