| Summary: | Ginger beverage and traditional herbal medicine industry spread all over
Indonesia. These industries produce waste of emprit ginger that has not been fully
utilized. Waste of emprit ginger is usually dumped or drained to be burned. The
objective of this study is to utilize waste of emprit ginger (Zingiber officinale) for
raw material of essential oils.
This study uses three methods of distillation, namely water distillation,
water-steam distillation and steam distillation. The raw materials used are wet and
dry waste of emprit ginger. Distillation carried out for 6 hours for each method.
The results showed that waste of emprit ginger can be used as raw material
for essential oils. The best method is water distillation with wet waste of emprit
ginger. This method produces yield 0.29% and the physical and chemical
properties according to SNI 06-1312-1998. The resulting essential oils have the
following properties, color : clear yellow, specific gravity : 0.879, refractive index
: 1,483, optical rotation : (-31o) and zingiberene content : 16.73%. Economically,
distillation of waste of emprit ginger is feasible to develop. |
