Characteristic of briquette from kemiri sunan (Reutealis trisperma) shell at several binder ratios

Abstract

Kemiri Sunan (Reutealis trisperma) can be used as raw material of biodiesel. Production of biodiesel from Kemiri Sunan generates shell as waste, that can be utilized as briquette material. During production process, adding binder for briquette is a must in order to create solid and hard shell Kemiri Sunan briquette. This study aims to find out the best ratio of binder (cassava starch) at the production of briquette. Kemiri Sunan was carbonized, grinded (mesh 30) and mixed with some binder ratios, then molded. The ratio of binder and Kemiri Sunan shell were 2:100, 4:100, 6:100, 8:100 and 10:100 (w/w). The study showed that binder ratio affected characteristic of Kemiri Sunan briquette. The best ratio was 6:100 with characteristics: moisture content was 5.5%, ash content was 6.6%, fixed carbon was 49.94%, calorific value was 6.372 cal/g and burning time was 101 min.
