		abstract={Essential oils are obtained from parts of roots, skins, stems, leaves, fruits, seeds, or from flowers by means of distillation. Lemongrass oil has not been commercially produced in Indonesia. This study was aimed to determine the effect of particle size of materials used in steam and water type distillate?s and the amount of water used in the distillation on the yield of essential oils produced by lemon grass. This research was conducted at Laboratory of Biosystem and Food Technology Laboratory of Faculty of Agriculture, University of Sumatera Utara from January to February 2018 by using factorial completely randomized design consisting of 2 treatments ie 3 levels and 3 replications, namely: first factor was the size of lemongrass particles consisting of 3 levels: (1 cm particle size, 2 cm particle size, 3 cm particle size) and the second factor was the amount of water consisting of 3 levels: (30 liter,35 liter, 40 liter).
The results showed that the best essential oil was found in the combination of 1 cm particle size and 40 liters of water with the highest yield of lemongrass oil and the highest alcohol solubility of 0.2%, and 1: 2. The lowest value of lemongrass oil yield and the solubility of alcohol was found in combination size of material 3 cm and amount water of 30 liters i.e 0,05% and 1: 5,3. The color of lemongrass oil yellow to yellow-red with hue range 47,02732-59,18429.}
