The aim of the study was to evaluate antimicrobial activity of essential oil from plants as natural antimicrobial to inhibit Listeria monocytogenes. A total 6 essential oil extracted from galangal (Alpinia galanga), ginger (Zingiber officinale), lemongrass (Cymbopogon citratus), orange skin (Citrus sinensis), rosemary (Rosmarinus officinalis) and turmeric (Curcuma longa). By using Minimum Inhibitory Concentration (MIC), the highest and the lowest concentration of essential oil to inhibit the growth of L. monocytogenes was found on turmeric (7.394 % + 0.028%) and lemongrass oil (0.219 % + 0.001 %), respectively. By using disc diffusion assay, the highest and the lowest antimicrobial activity against L. monocytogenes was shown by lemongrass oil (7.460 + 2.792 mm) and orange skin oil (0 + 0 mm), respectively. Out of the essential oil tested, lemongrass oil showed the most promising antibacterial activity inhibit L. monocytogenes.
