PENINGKATAN KADAR PATCHOULI ALKOHOL MINYAK NILAM (Pogostemon cablin Benth) DENGAN MENGGUNAKAN MEMBRAN SELULOSA ASETAT Increase of the Content of Patchouli Alcohol in Patchouli Oil (Pogostemon cablin Benth) Using Cellulose Acetate Membrane

The aims of this research were to increase patchouli alcohol content of patchouli oil using cellulose acetate membrane and evaluated performance  of the membrane. The nanofiltration  cellulose acetate membrane used in this study was the Vivaspin 15R. The filtration process of patchouli oil was carried out using centrifugation speed 212, 850 and 1912 g, and centrifugation time 10, 20, 30, 40, 50 and 6 minutes. Analysis of patchouli oil was carried out using gas chromatography, meanwhile  the separation performance membrane can be described as a permeability  (flux) and selectivity. The nanofiltration  process of patchouli oil using cellulose acetate membrane showed that the patchouli  alcohol content increase 2 times (58.11 %) of the initial content of patchouli alcohol (30.08 %) by using centrifugation speed of 1912 g and centrifugation time of 50 minutes. There are significant effect of centrifugation speed and centrifugation time on patchouli alcohol content, flux and selectivity. The highest value of flux is 166,81 L/m2.jam and selectivity is 44.91 %.ABSTRAKTelah dilakukan penelitian yang bertujuan untuk meningkatkan kadar patchouli alkohol dalam minyak nilam dengan menggunakan membran nanofiltrasi  selulosa asetat dan mengevaluasi  kinerja membran yang digunakan. Membran yang digunakan adalah membran nanofiltrasi selulosa asetat tipe Vivaspin 15R. Proses filtrasi  minyak  nilam  dilakukan dengan menggunakan kecepatan sentrifugasi 212 , 850, dan 1912 g serta  waktu sentrifugasi 10, 20, 30, 40, 50, dan 60 menit.  �adar patchouli  alkohol  di analisis menggunakan kromatografi  gas, sedangkan kinerja  membran dinyatakan sebagai permeabilitas (fluks) dan selektivitas. Hasil penelitian menunjukkan bahwa filtrasi dengan menggunakan membran nanofiltrasi selulosa asetat dapat meningkatkan  kadar patchouli  alkohol  sebesar 2 kali (61,52 %) dari kadar patchouli alkohol awal (30,08%) pada kecepatan sentrifgasi 1912 g dan waktu sentrifugasi 50 menit. Kecepatan dan waktu sentrifugasi berpengaruh signifikan terhadap nilai fluks dan selektivitas membran �ilai fluks tertinggi diperoleh sebesar 166,81 L/m2.jam dan selektivitas membran sebesar 44,91 %.
