Analisis Spektrum Near Infrared Reflectance Minyak Nilam yang Dicampur dengan Minyak Kelapa

Abstract

This study aims to analyze the characteristics of the patchouli oil spectrum and changes in its characteristics when mixed with coconut oil. This study was conducted using patchouli oil and coconut oil, with 5 treatments namely: thefirst sample is 100% patchouli oil,, the second sample treatment of coconut oil 100%, the third sample treatment is coconut oil mixed patchouli oil 75%:25%, fourth sample treatment of coconut oil mixed patchouli oil 80%:20%, fifth sample treatment of coconut oil mixed patchouli oil 90%:10%. This research uses the Self developed FT-IR SCIENCE AND TECHNOLOGY T-1516 tool used to acquire spectrum and Unscrambler software ® X version 10.1 used to process data. The results obtained in this study are that patchouli oil and coconut oil have relatively similar characteristics. The more coconut oil content is mixed into patchouli oil then the spectrum produced tends to be the same as coconut oil, while if less coconut oil content is mixed then the spectrum produced also tends to be the same as patchouli oil. The oil spectrum has 7 vibrations that signify the presence of molecules CH, CH2, CH3,ROH and H2O.
