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

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
