| Summary: | Vetiver oil (Vetiveria Zizanioides (L.) Nash) is one of the top export non-timber commodities of forestry which has a high economic value. Indonesia is the third largest Vetiver oil producing country that is centered in Garut Region. Post-harvest treatment is the most economical effort that can be applied in the local distillation industry to optimize the economic value of the Vetiver oil production. Distillation was run using water and steam distillation method for 9 hours length.
The preliminary treatment variations of vetiver root are: fresh without washing, sun-drying without washing, fresh with washing and sun-drying with washing. The evaluated parameters include water content of vetiver root, yield (wet based and dry based), distillation speed, time prediction of distillation. The results showed that the sun-drying with washing resulted in the highest wet based yield as much as 0.320%. Meanwhile, the highest amount of dry based yield is produced by fresh-washing treatment of 0.779%. Besides, the fresh-washing treatment has the highest distillation speed. From the fastest to the slowest distillation time based on the prediction sequentially is sun-drying without washing, sun-drying -washing, fresh without washing and fresh -washing respectively 11 hours; 12 hours; 12.5 hours; and 13 hours.
