Malacca is one of traditional medicine that possesses a potent antimicrobial activity. This study aims to determine the inhibitory activity of Malacca leaf extract on the growth of Salmonella sp in vitro. The bacteria was obtained from Microbiology Laboratory of the Faculty of Veterinary Medicine, Universitas Syiah Kuala. The study was conducted using n-hexane extract, ethyl acetate extract and ethanol of malacca leaves with dilution concentrations of 5%, 25%, and 50%.The inhibitory property of malacca leaf was tested using Kirby-Bauer method. Data were analyzed descriptively. The results of this study indicate that n-hexane extract, ethyl acetate extract and ethanol extract of malacca leaves can inhibit the growth of Salmonella sp. The n-hexane extract of malacca leaves showed a greater inhibition than the ethyl acetate and ethanol extract of malacca leaves. n-hexane extract with a concentration of 5%, 25%, and 50% showed average diameter inhibition of 1.35 mm (weak), 4.97 mm (moderate), and 12.87 mm (strong), respectively ethyl acetate extract with a concentration of 5%, 25%, and 50% showed average diameter inhibition of 2.00 mm (weak), 5.72 mm (moderate), and 7.58 mm (moderate), whereas in ethanol extract were 0.47 mm (weak), 2.58 mm (weak), and 4.35 mm (weak), repectively. The clear zone areas in negative and positive control were 0.00 mm 20.00 mm, respectively. Malacca leaf extract possess inhibitory property against the growth of the Salmonella sp.
