Karakteristik Biodiesel Kemiri Sunan [Reutealis trisperma ( Blanco ) Airy Shaw] Menggunakan Proses Transesterifikasi Dua Tahap

Asif Aunillah, Dibyo Pranowo

Abstract


Biodiesel merupakan alternatif terbaik pengganti bahan bakar diesel yang bersumber dari fosil. Selain dapat digunakan secara langsung pada mesin tanpa modifikasi, biodiesel juga ramah lingkungan. Pengembangan biodiesel kedepan lebih diarahkan ke bahan nonpangan. Salah satu bahan nonpangan yang berpotensi sebagai bahan biodiesel adalah kemiri sunan [Reutealis trisperma (Blanco) Airy Shaw]. Proses produksi biodiesel minyak kemiri sunan saat ini masih menghasilkan biodiesel yang belum memenuhi Standar Nasional Indonesia (SNI). Penelitian ini dilakukan di Lembaga Minyak dan Gas serta di Balai Penelitian Tanaman Industri dan Penyegar bulan November 2011, bertujuan mengevaluasi karakteristik biodiesel kemiri sunan dan membandingkannya dengan SNI (SNI-04-7182-2006) dan standar USA (ASTM D6751). Metode pembuatan biodiesel menggunakan proses transesterifikasi dua tahap. Hasil yang diperoleh menunjukkan bahwa rendemen biodiesel kemiri sunan mencapai 88% dari volume minyak. Dari 18 kriteria yang diamati, hanya residu karbon yang belum memenui kriteria SNI. Sedangkan untuk standar USA, yang belum memenuhi kriteria adalah residu karbon dan titik nyala.

 

The Characteristic Of The Philippine Tung [Reutealis Trisperma(Blanco) Airy Shaw] Biodiesel Processed Through Two Step Transesterification Process

ABSTRACT

Biodiesel is likely to be the best alternative to replace diesel derived fuel from fossil. It may be used directly onto machines without any necessary modification and be environmental friendly. Biodiesel development in the future will focus on non-edible vegetable oils of many potential sources. Philippine tung [Reutealis trisperma (Blanco) Airy Shaw] might be considered. However, biodiesel production at present has not been standarized by  Indonesian National Standard (SNI). A study was conducted at the Research and Development Center for Oil and Gas Technology and Indonesian Research Institute for Industrial and Beverages Crops on November 2011. The objective of this study was to evaluate the characteristics of Philippine Tung biodiesel and compared with SNI (SNI-04-7182-2006) and USA standart (ASTM D6751). The method used was a two-stage transesterification process. The result showed that the ratio of biodiesel to total oil volume (v/v) was 88%. From 18 parameters on SNI based there was only carbon residue which is not meet SNI. While based on US standard, flash point and carbon residue didn’t meet with the criteria.
