THE ANTIBACTERIAL ACTIVITIES OF AROMATHERAPY ESSENTIAL OILS OF LAVENDER (LAVANDULA ANGUSTIFOLIA MILL), ROSEMARY (ROSMARINUS OFFICINALIS L.) AND YLANG-YLANG (CANANGA ODORATA (LAMK.) HOOK) AGAINST AIRBORNE BACTERIA

Abstract

Essential oils have long been used in history to help aid a variety of health concerns. With the wide range of aromatherapy oils available, people are finding more and more uses for them, especially in the home and at work in getting good air quality. Many ways are made to achieve good air quality and free from microorganisms both pathogens and non-pathogens with the use of air filters, ultraviolet light, and which is now developed with aromatherapy. Lavender (Lavandula angustifolia Mill), rosemary (Rosmarinus officinalis L.), and ylang-ylang (Cananga odorata (Lamk.) Hook) essential oils have been used as aromatheraphy. The observing ungrowth bacterial colonies based on the time of evaporation of aromatherapy and the concentration of essential oils, can be searched that has the best antibacterial effect. The replica platting method was used in this research to conduct antibacterial activities, determined the inhibitory concentration and to determine the evaporation time of lavender, rosemary, and ylang-ylang essential oils. The concentration variation of essential oil was 5%, 7.5%, and 10% v/v and also variation of evaporation time during 30, 60, and 90 min. The result showed that a minimum inhibitory concentration respectively, 5% v/v with effective duration in 60 min for lavender and ylang-ylang essential oils that be required to have the effect on reducing the population of airborne bacteria and 7.5% for rosemary with effective duration in 90 min.
