The utilization of corncob for the manufacture of charcoal briquette as an alternative fuel

Abstract Biomass of sweet corncob and birdlime that is much found in society is the garbage that until now have not widely used as a product that have value added. This research aims to use biomass of sweet corncob and the birdlime as an alternative fuel to substitute fossil energy sources. One alternative to make sweet corncob and birdlime as an alternative fuel is process them into charcoal briquettes so it can produces high calorific value. The process to make charcoal briquettes from corncob and birdlime is very easy which includes charcoal raw material drying, preparation of the adhesive, printing and drying the Briquettes. Besides, the testing of briquettes quality of sweet corncob includes: density (0.54 – 0.78 gr/cm3), calorific value (4936.454 cal/gr), water level (6.39%), ash level (3.8%), vaporized substance level (16.72%) and bonded carbon level (79.48%. Whereas, birdlime corncob include: density (0.61 – 1.3 gr /cm3), calorific value (6033.650 cal/gr), water level (6.83%), ash level (4.8%), vaporized substance level (18.41%) and bonded carbon level (76,48%).
