UJI EFEKTIVITAS EKSTRAK DAUN ILER-ILER (COLEUS SCUTELLARIOIDES (LINN.) BENTH) SEBAGAI ANTIBAKTERI STAPHYLOCOCCUS AUREUS

The research has been conducted in order to determine the effective concentration of leaf extract of Coleus scutellarioides to inhibit the growth of Staphylococcus aureus. The antibacterial test was using paper disc diffusion method, Leaf extract obtained by maceration
method, using methanol as a liquid solvent. This research used a Completely Randomized, 5 treatments variation of leaf extract (3.5%, 4.75%, 6%, 7.25% and 8.5%), and 5 replications. Tetracycline antibiotics were used as a comparison test. The results showed that the leaf
extract was effective to inhibit the growth of bacteria S. aureus. Antimicrobial with the largest diameter of inhibition was at concentrations of 7.25% (8.5 mm). While tetracycline was 4 mm. Antimicrobial inhibition was most effective at a concentration of 3.5%.
