AKTIVITAS ANTIBAKTERI EKSTRAK ETANOL BATANG Phytocrene macrophylla BLUME
ABSTRACT: Antibacterial
activity test has been done on Phytocrene macrophylla Blume stem ethanol
extracts. The aim of the research was to determine the antibacterial activity
of Phytocrene macrophylla Blume Stem
Ethanol extracts delivered from Gowa District of South Sulawesi by means of
Agar Diffusion. The results of the screening antibacterial activity of ethanol
extracts of stem Phytocrene macrophylla Blume possessed activity against
Escherichia coli, Streptococcus mutans, and Pseudomonas aeroginosa. At the minimum
inhibitory concentration tests used the concentrations of 0,2%, 0,4%, 0,6%,
0,8%, 1%, 5%, 10%, and 15% of the bacteria Streptococcus mutans, Pseudomonas
aeroginosa, and Escherichia coli can inhibit 0,2%. At the minimum kill
concentration test against the bacteria Streptococcus mutans and Pseudomonas
aeroginosa inhibited at the concentration of 0,8% and the bacteria Escherichia
coli at the concentration of 1%. The test results of antibacterial activity of
ethanol extract of stem Phytocrene macrophylla Blume at the concentrations of
0.8%, 1%, and 5% inhibited the growth of bacteria. The biggest inhibitory zone
of the test conducted, that is, at the concentration of 5% by 16 mm against to
the bacteria Pseudomonas aeroginosa and Streptococcus mutans, and 14 mm to
Escherichia coli.
