ENERGI ALTERNATIF BIOBRIKET DARI KOMBINASI LIMBAH AMPAS KOPI DAN LIMBAH BAWANG MERAH

Bio-briquettes have become a feasible method for achieving alternative energy and waste utilization goals. The approach of this research is to manufacture bio-briquettes by utilizing Robusta coffee grounds onion peels with optimal standards obtained from nourishment agricultural outgrowth in Brebes Regency. In experiments, 25% - 75%, 60% 40% composition ratio was used, 50% ratio. result the experiment demonstrate that mixture 75% most according SNI Quality Wood Charcoal Briquettes Number 01-6235-2000 calorific value 5000,15 cal/gram, water content 6,55%, ash 6,8%, volatile matter 41,87%, bG
