Essential oils are known as the flying oil (volatile oil) or the etheric oil (essential oil) is produced from plant oils and are easily vaporized without decomposition. Longae Curcuma or turmeric is one of spices and medicinal plants, native habitat of this plant covers an area of Asia, especially Southeast Asia.Essential oils are widely used in industry as a fragrance or flavoring (flavoring). Turmeric contains a chemical that has a physiological activity, namely: curcuminoid and essential oils. This research is aimed to look for the distillation process and the treatment method of the best raw materials to produce the essential oil of turmeric with high quality Existing research was only at a certain distillation method of distillation methods either boiled, steamed, or vapor as well as the treatment of certain raw materials as well. This research used to see the yield and quality (content Tumerone) but has never been a study comparing treatment-related raw materials and distillation method for the following essential oils. Thus, this study needs to be done. The research is started with the treatment raw materials such as milled turmeric and mashed turmeric and water distillation, water-steam distillation, and steam distillation as well. Otherwise, turmeric essential oil is tested with GC-MS for analyzing chemical and physical properties. The chemical properties such as Tumerone compound content and physical properties such as colour, flavour, optical rotation, density, refractive index, etc. Result of the research indicated that the treatment of raw materials and distillation methods which produced the highest quantity (rendemen) was milled treatment and water distillation, while for the quality (chemical properties) was milled treatment and water-steam distillation. The highest quantity (rendemen) was 0.56% and the highest Tumerone compound content was 74.17%.
