Pengaruh Konsentrasi Perekat Daun Jambu Mete dan Tekanan Pengempaan dalam Pembuatan Briket dari Sekam Padi dan Ketaman Kayu

Abstract

Briquette is usually made using binder. Binder can embed charcoal each other to form strong and compact briquettes. Some other variables beside binder that influence the quality of briquettes include raw material, compacting presseure and carbonization process. This research used rice husk and shaving woods as raw material with cashew leaves as binder. All variables affect the content of fixed carbon of the briquettes that influence the caloric value of the briquettes. The caloric value is the most important factor for determining the quality of the briquettes. In this research, the highest caloric value of the briquettes was 3.045,8271 cal/g. It was achieved when rice husk and shaving wood were carbonized by method 1 with compaction pressure of 85 kg/cm2 and binder concentration of 15% where the ratio of rice husks and wood shaving was1: 1 with particle size of 100 mesh. The caloricvalue of the briquettes was still very low and did not meet the qualification of Indonesian standard for briquettes. Based on the strength test, cashew leaves couldn’t be used as briquette’s binder. The produced briquettes that used cashew leaves as binder had soft structure and easily destroyed.
