UJI ANTIBAKTERI EKSTRAK BATANG KECOMBRANG (Nicolaia speciosa Horan) TERHADAP Staphylococcus aureus DAN Escherichia coli
Abstract: The aims of the
research were to learn capability antibacterial of kecombrang stem extract
againts the growth Staphylococus aureus and Escherichia coli and to determine
the Minimum Inhibitory Concentration (MIC) score. This research conducted an
experimently by the antibacterial activity of
kecombrang stem extracts by using polar, nonpolar and semipolar solvents
against S. aureus and E. coli. The antibacterial activity was tested by using paper disk
diffusion method and Minimum Inhibitory Concentration (MIC) score by
using dilution. The data obtained were tabulated and analysed descriptively.
The antibacterial test show that ethyl acetate extract formed clear zone ranged
between 1-3,5 mm in diameters, wich was higher than water extract (0,73-3,16
mm) and hexane extract (0,8-1,8 mm) kecombrang stem. Scores MIC show that ethyl
acetate extract of kecombrang stem that inhibited the growth of E. coli dan S.
aureus at concentration of 20 and 40% and extract water of kecombrang stem inhibited the growth of E. coli at concentration 80% and S. aureus
at concentration of 40%. Meanwhile hexane extract of kecombrang stem inhibited
the growth of E. coli and S. aureus at concentration 100%.
