Abstract

Typhoid fever is an acute infectious disease in the small intestine with symptoms of fever more than one week, resulting in digestive disorders and can reduce the level of consciousness. The bacteria that cause typhoid fever are Salmonella typhi. Pucuk merah leaves (Syzygium myrtifolium Walp.) has antibacterial compounds that are effective in inhibiting bacterial growth. This study aims to examine whether antibacterial substances in pucuk merah have an influence on the growth of S.typhi. Pucuk merah leaf simplicia was extracted using three types of solvents which had different levels of polarity; ethanol, ethyl acetate, and n-hexane by maceration method. This type of research is experimental laboratory with diffusion and dilution methods. This study used concentrations of 35%, 30%, 25% and 20% in diffusion method. Meanwhile the dilution method used concentrations of 30%, 15%, 7.5%, 3.75%, 1.875%, 0.94%, 0.468% and 0.234% and positive controls (bacterial suspension) and negative controls (most active extracts) . The results showed that 20% ethyl acetate extract was the most active concentration. The results of testing the antibacterial activity with the dilution method showed the absence of a minimum inhibitory concentration (MIC) value and the minimum bactericidal concentration (MBC) value of the ethyl acetate extract was 15%. Keywords : antibacterial, pucuk merah leaf, Salmonella typhi.
