One of the medicinal plants in Indonesia is rambutan (Passiflora foetida L.). Some of the chemical substances contained in the leaves of rambusa include alkaloids, flavonoids, steroids, and triterpenoids which have an antibacterial effect. This study aims to determine the activity and concentration of effective antibacterial from the extract of rambutan leaves on the growth of Pseudomonas aeruginosa bacteria.
