Abstract
The active substance of Curcuma xanthorrhiza Roxb. was
influenced by environment. It may be influence antibacterial activity
of 96% ethanol extract Curcuma xanthorrhiza rhizome. The aim of
this study was to investigate the antibacterial activity of96% ethanol
extract of Curcuma xanthorrhiza rhizome from three different
location: Sukabumi, Lembang and Bogor against Bacillus cereus.
The antibacterial activity was measured in terms ofthe MIC and the
differences was analysed with anova use inhibition zone diameters
variable. MIC determined by well diffusion method MICs of 96%
ethanol extract Curcuma xanthorrhiza rhizome from Sukabumi,
Lembang and Bogor against Bacillus cereus, respectively were 400.
400 and 100 pglml. The result ofanalysis ofvarian in concentration
500-1500 pglml show that 96% ethanol extract of Curcuma
xanthorrhiza rhizome from three different location have significant
difference. The best activity has been showed by extract from
Lembangfollowed by Bogor and then Sukabumi.
