Abstract

A study has been conducted about antibacterial activity of starfruit leaves extract (Averrhoa bilimbi L.) against bacteria Shigella dysenteriae. Starfruit leaves extract contains flavonoids, tanins, alkaloids and saponins. The experiment was performed to see the inhibition zone formed by starfruit leaves extract in the surface of agar that has been cultivated bacteria Shigella dysenteriae. Bacteria that have been isolated and rejuvenated for 24 hours were then suspended. Planting was done by wiping above of Mueller Hinton Agar. The experiment used 5 treatment groups and 5 repetitions. Group 1 (NCG) is a negative control group that used sterile distilled water, group II (PCG) used ciprofloxacin antibiotic discs in concentrations of 5 μg, group III, IV, and V is the experimental group namely KE 1, KE 2 and KE 3 with concentration extract of 100%, 50% and 25%. Inhibition zone around the disc at a concentration of 100%, 50%, and 25% can be measured after left for 24 hours in an incubator. Inhibition zone formed was statistically analyzed and showed significant differences in each treatment group with NCG and PCG. The results show that 70% ethanol extract of starfruit leaves has antibacterial activity against bacteria Shigella dysenteriae. Keywords : Starfruit, antibacterial, Shigella dysenteriae
