ADSORBSI CAMPHENE DENGAN BENTONIT UNTUK MENINGKATKAN KADAR ZINGIBERENE DALAM MINYAK JAHE DENGAN VARIABEL WAKTU DAN SUHU ADSORBSI (Camphene Adsorption with Bentonit to Improve The Content Zingiberene Ginger Oil with Variable in Time and Temperature Adsorption)

Abstract

Raw materials used in this lab is the result of oil ginger essential oil of ginger in Ungaran, using water and steam distillation method. At this lab using adsorption method, using the bentonite as adsorbent with a magnetic stirrer hot plate. Selection of bentonite as adsorbent because bentonite has the ability to adsorbs camphene compounds. With reduced levels of camphene in ginger oil, then zingiberene levels will increase. Based on practice is known that the longer the time it adsorbs the more compounds camphene be absorbed by bentonite, so that sooner zingiberene levels increased. Meanwhile, the higher the temperature it adsorbs the compounds that camphene be absorbed by bentonite back zingiberene apart so that the levels will decrease. Differences in variables such as time and temperature adsorption adsorbs very influential on lab results. This variable distinction serves to determine optimum operating conditions in the process of adsorption ginger oil with bentonite. Factors that affect the process adsrobi are temperature, time, stirring speed, absorbent surface area and concentration of the adsorbate.
