Aktivitas Anti Bakteri Dan Anti Jamur Pada Plectranthus Javanicus (Blume) Benth., P. Galeatus Vahl Dan Scutellaria Slametensis Sudarmono & Conn (Lamiaceae)

Anti bacteria and anti fungus activity of Plectanthus javanicus, P. galeatus and Scutellaria slametensis (Lamiaceae) was tested by using Bacillus subtilis (for gram positive testing), Pesudomonas aeruginosa (for gram negative testing) and Saccharomyces cerevisiae and Candida albicans (for anti fungus testing). Leaves were extracted by using n-heksana, etil acetate and methanol (with the concentration of 50 μg/μl., 100 μg/μl and 200 μg/ μl). The results showed that leaves extract of P. javanicus and P. galeatus (using etil acetate and methanol) have anti bacteria activity against P. aeruginosa. All extracts (using n-heksana, etil acetate and methanol, in concentration of 200 μg/μl.) of P. javanicus leaves also showed anti bacteria activity on Bacillus subtilis; whereas the leaves of S. slametensis has anti fungus activity on S. cerevisiae in all concentrations of n-heksana (50 μg/μl., 100 μg/μl. and 200 μg/μl.) as well as anti bacteria activity on P. aeruginosa using methanol extract in the concentration of 100 μg/μl.and 200 μg/μl.
