ABSTRACT. Niken Harimurti, Tatang H Soerawidjaja, Djajeng Sumangat and Risfaheri. 2012. Patchouly oil extraction with hydrodiffusiontechnique at 1 – 3 bar pressure. Patchouli oil is a type of essential oil which was obtained by pressured steam or water distillation of Pogostemoncablin Benth dried leaves. Key components of patchouli oil are patchouli alcohol and norpatchoulenol which become indicators in determiningpatchouli oil quality. This research was objected to evaluate patchouli oil extraction with hydrodiffusion technique at 1-3 bar pressure. This experimentwas designed with response surface method, with pressure (Low level 1 bar, high level 3 bars) and time (low level 3 hours, high level 12 hours) asvariables. Yield, density, refractive index, optical polarization, solubility in ethanol 90%, acid number and ester number were evaluated as the responsof the two variables. Analysis of respons surface method showed that increasing extraction pressure significantly influence in acid number while theyield of patchouli oil was influenced by pressure, time and interaction of both. Results of qualitative analysis by GC / MS showed that oil samples atno 11 (pressure 3 bar for 3 hours) contained patchouli alcohol 29.66% and norpatchoulenol 0.68%. Microhistology identification of patchouli leavesbefore and after extraction showed reduction of glandular trichomas diameter about 61.2%. Based on quality parameters values, statistical and GC /MS analysis results, the best condition for hydrodiffusion process was at 3 bar pressure for 3 hours.Keywords: patchouli oil, hydrodiffusion, patchouli alcohol, norpatchoulenol

Abstract

Penelitian biokonversi buah semu jambu mente menjadi konsentrat protein mikrobial dilakukan di Laboratorium Fisiologi Hasil, Balai Penelitian Tanaman Rempah dan Obat mulai bulan April 1999 sampai Maret 2000. Tujuan penelitian ada-lah untuk memproduksi konsentrat protein mikrobial dengan menggunakan buah semu jambu mente kering sebagai substratnya melalui proses fermentasi substrat padat. Perlakuan yang dicobakan adalah (A) amonium sulfat sebagai nutrien dengan konsentrasi 0, 1, 2 dan 3% dan (B) lama fermentasi yaitu 48, 72, 96, 120 dan 144 jam. Inokulan yang digunakan dalam fer-mentasi adalah Aspergillus niger. Rancang-an percobaan yang digunakan adalah Rancangan Acak Lengkap yang disusun secara faktor tunggal, terdiri atas dua faktor dan tiga ulangan. Parameter pengamatan meliputi pertambahan bobot biomasa (%), kadar protein dari biomasa (konsentrat protein mikrobial) dan kandungan asam amino dari protein biomasa yang dihasilkan. Hasil penelitian menunjukkan bahwa makin tinggi konsentrasi amonium sulfat, maka kadar protein konsentrat mikrobialnya makin tinggi. Kadar protein tertinggi (17,001%) dicapai pada perlakuan konsen-trasi 3 % amonium sulfat dan lama fermen-tasi 72 jam. Konsentrat protein mikrobial yang dihasilkan mengandung beberapa asam amino esensial yaitu metionin, leusin, fenil alanin, treonin, valin, histidin, tapi tidak mengandung asam amino esensial lisin dan isoleusin. Pertambahan bobot biomasa (konsentrat protein mikrobial) yang tertinggi (0,63%) dihasilkan dengan perlakuan konsentrasi 2 % amonium sulfat dan lama fermentasi 96 jam.
