ANTIBACTERIAL ACTIVITY OF TIN LEAVES (Ficus carica L.) ETHANOL EXTRACT AGAINST THE BACTERIA Salmonella typhi

Tin (Ficus carica L.) is a plant from the Moraceae family that contains phytochemicals including alkaloids, flavonoids, saponins, phenols, steroids, tannins. The purpose of this research was to determine the antibacterial activity of ethanol extract of tin leaves against Salmonella typhi bacteria by using the disc diffusion method. Disc paper containing antimicrobials is placed on a medium that has been planted with microorganisms that will diffuse into the media, the clear area indicates an inhibition of microorganism growth. The concentrations of ethanol extract tin leaves used were 10% and 5%. The strength of antibacterial activity can be seen through the parameter of inhibitory strength. Inhibition area 20 mm or more (very strong), 10-20 mm (strong), 5-10 mm (medium) and 5 mm (less). The results showed that the ethanol extract of tin leaves had strong antibacterial activity.
