Abstract
This research purpose is to show the inhibition of the extract of ethanol and ethyl acetate stem bark and leaf of Raru according to the causes of bacterial E-coli (ATCC 25922) and St Aureus (ATCC 25923) with variation concentration 10%, 5%, 2.5% and 1.25%. Methods used were diffusion with disk blank paper and disk cloramphenicol as a control. The highest result observed on 10% concentration among the variation. This concentration then compared with control and the result as follow for stem bark of ethanol and ethyl acetate exctract for bacterial E-coli and St Aureus : 14.7 and 14.5 ; 11.6 and 13.5. for leaf : 14.6 and 13.5; 14.0 and 13.30
