    Abstract

    Research about essential oil extract from Pogostemon Cablin Benth (Patchouli leaves) has been done using Electrochemical Extractive Distillation Column. Sompe process variables that influenced in this process are weight ratio of Patchouli leaves to solvent voltage and pH. This research has been divided into two methods that are electrolyze and non-electrolyze process. For non-electrolyze process, variable used is Patchouli leaves to solvent ratio 1:10, 1:15, 1:20, and pH 4 and 6. For electrolyze process, it used the same condition as non-electrolyze with voltages 3, 6, 9, and 12 volts. The extractive process occured in an hour with temperature 80oC. In conclusion, the highest yield about 8.5% for ratio 1:10 and pH 4 for non-electrolyze process and 12.3% for ratio 1:10, pH 4 and 9 V for electrolyze process. The energy cost gives each kg of Patchouli oil is 183.775 IDR base on highest yield. If we compare the energy cost to selling price of Patchouli oil with market quality, it has good properties to SNI (The National Standard Quality of Indonesia) No. SNI 06-2385-1991. The characteristic give yellow color, fresh fragnance, viscosity 0.947, Index number 1.508, acid volue max. 2.76, ester value maximum 8.54, other materials: alcohols, fat are negatives.
