Abstract
Kecombrang (Nicolaia speciosa) is one of the plants is efficacious as body odor remover and unhealthy bacteria in the body due kecombrang plant contains compounds called polyphenols, saponins and flavonoids. Shigella sp. the bacteria that cause dysentery with clinical symptoms of diarrhea with mucus and blood. The purpose of this study to test the antibacterial activity against bacterial leaf extract kecombrang Shigella sp. Kecombrang leaves obtained from Pandeglang, Banten. Kecombrang leaves extracted by maceration using ethanol 96%. Kecombrang leaf extract dilutions made in a concentration of 25%, 50%, 75% and 100% with 2% DMSO as a diluent. Positive controls are used cotrimoxazole and 2% DMSO as a negative control. Antibacterial activity test conducted by diffusion method to determine the way of pitting diameter inhibition zone against Shigella sp. The results showed the chemical constituents kecombrang leaf extracts are polyphenols, saponins and flavonoids. At a concentration of 25%, 50%, 75% and 100% indicate growth inhibition zone against Shigella sp. and the statistical tests most active concentration was 75% at 14 mm.
