UJI KINERJA RANCANGAN ALAT DESTILASI UAP AIR PADA TEKANAN VAKUM UNTUK PRODUKSI MINYAK NILAM DENGAN VARIABEL METODE PENGERINGAN BAHAN BAKU (Performance Test of Water Vapor Distilation Design on Vacuum Pressure for Patchouli Oil Production With Variable Drying Method Raw Materials)

Abstract

Patchouli oil is categorized in with the main component of essential oil Patchouli Alcohol, patchouli leaves and stems contain this oil. Patchouli oil is good to have PA levels above 30%, clear yellow color and has a distinctive odor that difficult to remove, because the nature of a strong scent, patchouli oil widely used in perfumery and cosmetics industry. Patchouli oil is a commodity exports, Indonesian patchouli oil greatest supplier of the world (90%) so that patchouli oil has a good prospect for development. In this study, the raw material used Aceh patchouli leaves that have been dried by different methods and processed using a steam distillation in vacuum pressure with temperature 500C and pressure of -50 cmHg. From the research that has been done the oil with drying aired method bright yellow with a yield of 2.37% and a density of 0.94 and Patchouli Alcohol content of 22.11%. while the yield generated by the method of drying diwah direct sun light yellow with a yield of 1.15% and a density of 0.95 and Patchouli Alcohol levels of 29.708%.
