Fabrication and characterization of activated charcoal briquette made from sago stem midrib have been performed. The sago stem midrib firstly dried before carbonized using kiln drum method. Subsequently, the sago stem midrib charcoal was activated using electric furnace with 650°C of temperature for 5 minutes. Then, the activated briquette mashed and sieved by 80-mesh strainer before moulded into a compaction pressure. The pressure that applied were 34.66 kg/cm 2 , 69,32 kg/cm 2  and 103,98 kg/cm 2 . Ignition time, burning rate, and burning test were performed to charaterize the briquette quality. The result shown that the higher the pressure applied, the lower ignition time, burning rate and the longer of burning time of sago stem midrib briquette, compared to the unactivated sago stem midrib briquette.
