| dc.description.abstract | Briquette is a solid fuel that made from organic waste and mixed with other materials by pressure. In this
research, the raw material used is waste of sengon sawdust and used tapioca flour as binder. This study
focused on the effect of temperature pressure variations on ignition time, burning time and the rate of
combustions of briquette charcoal sengon. Pyrolisis temperature 400 ºC and variation of temperature
pressure were 150ºC, 175ºC, and 200ºC. The results of research on suppression temperature of 200 ºC, the
ignition time is getting longer, because the more water out of charcoal and tapioca, it makes active
adhesive particles to bind the charcoal leading to higher density briquettes. On suppression temperature
of 200 , the burning time is getting longer, because more and more moisture out of charcoal and tapioca,
so that more particles tapioca that binds the active charcoal. On pressure of 200 , the slower the rate of
combustion because the evaporation of the water content of charcoal and tapioca so that the higher the
water content out of the adhesive will more actively bind charcoal and increase density of briquettes. | en_US |
