There are a lot of uses of patchouli. For example, it is used in pharmaceutical industry that is effective for fungal and bacterial infection and is of great help for insect bites. In cosmetic industry, with its excellent diuretic properties, it is effective in fighting water retention and to break up cellulite, easing constipation and helping to reduce weight. This research is conducted to study the effect of amount of patchouli leaves (raw material) on the extraction process and to find the optimum extraction time in the extraction of patchouli oil. In the first experiment, five different amounts of patchouli leaves, varying from 250gram to 450gram will be applied to identify the effect of amount of raw material in the extraction process. In the second experiment, different extraction times which are 3hour, 3.5hour, 4hour, 4.5hour and 5hour are used to find the optimum extraction time for extraction of patchouli. When the amount of patchouli leaves used is increase, the percentage of oil yield is also increase. 450gram patchouli leaves produced the highest yield which is 1.61%. When the extraction time is increased, the percentage of oil yield is also increased.
