This study aims to determine the value of rendement of red ginger essential oil from red ginger waste that has been dried through the steam distillation process. Red ginger waste from fresh red ginger that has been taken the juice then dried with the help of sunlight for 1,2,3 and 4 days. The dried red ginger waste then subjected to steam distillation for 3 and 7 hours to determine the rendement of the red ginger essential oil produced. Based on the study, the rendement of each essential oil on 3 hours distillation time were 0.2%; 0.6%; 1%; and 0.8%, while at 7 hours distillation time the rendement were 0.2%; 0.6%; 0.75%; and 0.6%. The rendement was differences because of in 7 hours time distillation; the essential oil could be degradation process so that the rendement was higher in 3 hours time distillation. The highest rendement was obtained by steam distillation of red ginger waste with 3 days of drying time.
Key words: red ginger / essential oil / steam distillation / rendement
