Dreg and husk of jathropa seed and the mixed of organic garbage for making the Briquette as an alternatif energy

Jathropa seed waste is one of organic garbage that still has benefit value, one of the benefits is used for briquette produced. There are two kinds of jathropa seed waste, which are dreg and husks of jathropa seed. Dreg and husks of jathropa are suitable materials for briquette production because they have under 20% of moisture content and high of carbon content. Whereas, rice husks is one of additional raw material for briquette production. The objectives of this research are to obtain the best briquette with raw materials variation composition and variation of binder content. The variation of raw material based on mass comparison are dreg: rice husk (20:80; 40:60; 80:20), dreg:husk (20:80; 40:60; 80:20), and husk rice husk (20:80; 40:60; 80:20). Briquette was made from pyrolysis process then the carbon result will be size reduced and screened. After process screening, carbon was mixed with binder then dried in the oven. Briquette that produced was proximate analyzed. For all variable was found the best briquette with mass comparison of raw materials from rice husk: husk of jathropa seed (80:20) with 10% binder content, 8.45% of moisture content, 8.36% of volatile content, 63.05% of carbon content and 5743.44 cal/gram.
