Abstract

Indonesia as the third largest grain producer in the world produces large amounts of bran. High contain Free Fatty Acid (FFA) in rice bran oil causes it can be converted into the fatty acid ethyl esters (biodiesel) by esterification and transesterification methods. The rice bran oil was obtained by rice bran extraction using n-hexane. The esterification process was catalyzed by HCl. In this study, the transesterification process to convert triglycerides into ethyl esters (biodiesel) was conducted by the addition of KOH as a neutralizer and a catalyst Oil and ethanol by ratio 1:6 using 0,5% KOH  as catalysator were reacted by utilizing 47 kHz ultrasonic wave for 45, 60 and 75 minutes. Biodiesel conversion value obtained were 49,23%; 70,55% and 52,04% respectively. Biodiesel product spectrum was analyzed using FTIR and GCMS instrument. The density, viscosity and flash point is also measured.  FTIR analysis on all variations give similar data spectrum, where the ethyl ester products are characterized by typical bands at specific frequencies such as -C=O; -C-C; -C-H (sp3) and = C-H (sp2) stretch. Based on the data from GCMS spectrum, the product components are ethyl palmitate, ethyl linoleate, ethyl stearate and ethyl oleate.

Abstract

Potensi keanekaragaman tumbuhan liar yang bermanfaat sebagai obat-obatan masih banyak diabaikan oleh masyarakat. Permasalahan ini terjadi antara lain karena pengetahuan yang dimiliki masyarakat masih tergolong rendah. Program pengembangan desa mitra bertujuan untuk meningkatkan pertisipasi masyarakat dalam mendukung tercapainya pusat konservasi tumbuhan obat (TO) di Sulawesi Tengah. Metode yang diterapkan adalah community development atau pengembangan masyarakat dengan langkah-langkah operasional adalah pembentukan kebun konservasi dan klinik tumbuhan obat dengan sasaran mengusahakan sebanyak mungkin tumbuhan yang berpotensi sebagai tumbuhan obat tradisional sebagai sumber plasma nutfa agar tidak punah dan menjadi sumber informasi. Hasil pelaksanaan pelatihan teknik konservasi tumbuhan obat untuk mendukung progam penyediaan obat herbal di Sulawesi Tengah kepada masyarakat di Desa Pakuli Kecamatan Gumbasa berlangsung dengan baik dan dapat diadopsi oleh masyarakat yang diindikasikan dengan kegiatan penanaman tumbuhan obat oleh masyarakat di halaman pekarangan rumah masing-masing. Pelaksanaan penyuluhan yang diikuti sebanyak 35 orang peserta dari 2 kelompok mitra dapat meningkatkan pengetahuan masyarakat yang ditandai dengan meningkatnya ketrampilan pada saat praktek budidaya tumbuhan obat, baik yang dilaksanakan di areal konservasi maupun di lahan pekarangan. Dengan konservasi tumbuhan obat terutama yang tergolong langka, maka masyarakat dapat mendekatkan diri dengan tumbuhan obat langka tersebut untuk kepentingan penyediaan obat herbal bagi anggota keluarganya
