Abstract

Bacterial infections are a serious problem in health. Natural antibacterial which can be used to inhibit and kill bacteria, namely leaves of rambusa (Passiflora foetida L.) which have a chemical content of flavonoids, alkaloids, tannins, saponins and triterpenoids. The purpose of this study was to determine the antibacterial activity of ethanol extract of leaves of rambusa (Passiflora foetida L.) against Pseudomonas aeruginosa ATCC 27853. Rambusa leaves were extracted using 96% ethanol and then evaporated using an evaporation until the extract became thick. The thick extract was then tested for antibacterial activity by diffusion and dilution methods. Diffusion test with a concentration of 75%, 50%, 25% and negative control of chloramphenicol 25 mg / 10 ml. dilution method with 75% dilution series; 37.5%; 18.75%; 9.37%; 4.68%; 2.34%; 1.17%; 0.58%, 0.29%; 0.14%. The results showed that the antibacterial activity of rambusa leaves ethanol extract had antibacterial activity. Ethanol extract of rambusa leaves at a concentration of 75% has the highest antibacterial activity, with a inhibition zone of 15.33 mm. Minimum inhibitory concentration of rambusa leaves ethanol extract was not seen because extracts that were too concentrated and Minimum Killer concentration (KBM) ethanol extract of rambusa leaves which could kill Pseudomonas aeruginosa ATCC 27853 were 37.5% concentrations. Keywords: rambusa leaves, ethanol extract, antibacterial activity test, Pseudomonas aeruginosa.
