Potensi Ekstrak Daun Kirinyuh (Chromolaena odorata) dalam Menghambat Bakteri Patogen (E. sakazakii, S. typi, dan L. monocytogenes)

Kirinyuh (Chromolaena odorata) is one of the wild plants found that difficult to eradicate because it has a high defense, so this considered weed plant detrimental farmers and planters. However, kirinyuh potential be developed as an antibacterial. One natural ingredients show pharmacological effects flavonoids. This study aims determine antibacterial activity, effective concentration extract in inhibiting growth Enterobacter sakazakii, Salmonellla typi, Listeria monocytogenes bacteria. To get used extraction method by maceration immersion using 96% ethanol solvent. The was 20%, 40%, 60%, 80%, 100%. While positive control Ampicillin negative 96%, for testing activity carried out well difsusion method. results test were analyzed ANOVA with 95% confidance level continued Duncan’s Multiple Range Test (DMRT). showed concentrations 100% had given inhibitory At 100%, more against bacteria Salmonella compared other concentrations. increase larger diameter inhibition zone bacterial growth. power sakazakii average value 6,66 mm, typi xone 4,83 moncytogenes 5, 60 mm.
