OPTIMASI KONDISI OPERASI PADA ADSORPSI DENGAN BENTONIT PADA PENINGKATAN KADAR ZINGIBEREN DALAM MINYAK JAHE (Optimation of Operating Conditions In Adsorbtion Using Bentonit At Elevated Level in Ginger Oil Zingiberen)

Abstract

Ginger oil is a yellow liquid brown to reddish, easily evaporate at room temperature, density smaller than the density of water, has a bitter taste, smell typical fragrant ginger plant, soluble in organic solvents and insoluble in water. The main components in ginger oil is zingiberen. To increase levels of zingiberen the use of bentonite as adsorbent (adsorbent). At this lab using a Hot Plate Magnetic Stirer. Based on ginger oil analysis test by using GC (Gas Chromatography) has done that operating conditions affect the result of increased levels of zingiberene. In this experiment using experimental design calculations, obtain optimum operating conditions, namely bentonite weight of 4.3 grams, stirring speed of 60 rpm, temperature 40°C and the time for 10 minutes. Zingiberene levels obtained with% 10.67% and 15.05% highest probability. Operating conditions that most influence is the temperature. Factors that influence a comparison of ginger oil and bentonite is used, the speed of rotation, temperature, and time. Keywords : Ginger oil, zingiberene, bentonit, camphene, adsorption
