Abstract

Rambusa leaves (Passiflora foetida L.) had a chemical content of flavonoids, alkaloids, tannins, saponins and triterpenoids which were thought to had antibacterial activity. This research aims to determine the antibacterial activity from ethanol extract of rombusa leaves (family of Passifloraceae) against Klebsiella pneumonia ATCC 10031. Rambusa leaves were extracted using 96% ethanol and then evaporated using an evaporation until the extract became thick. The thick extract was tested for antibacterial activity using diffusion and dilution methods. Diffusion method with concentration of 55%, 40%, 20% and positive control of chloramphenicol 0,21%. Dilution method used 75% dilution series; 55%; 27,5%; 13,75%; 6,87%; 3,43%; 1,71%; 0,85%; 0,42%; 0,21%; 0,10%. The results showed that the ethanol extract of rambusa leaves had antibacterial activity. Ethanol extract of rambusa leaves with concentration of 55% had the highest antibacterial activity with diameter of inhibition zone is 13.67 mm. Based on the MKC (Minimum Killing Concentration) test, it was found that concentration ethanol extract of rambusa leaves can killing Klebsiella pneumonia ATCC 10031 is 27.5%. Keyword: rambusa leaves, ethanol extract, Klebsiella pneumonia ATCC 10031, antibacterial test.
