Abstract

The development of cassava stem waste from year to year is increasing and the utilization
of cassava stem waste is not optimal because only 10% of the cassava stem height used for
replanting with the remaining 90% is not utilized at all. This study aims to utilize cassava stem
waste into charcoal briquettes as an alternative fuel by carbonizing or fabricating using fast
pyrolysis reactors at 350 ° C for 4 hours to produce charcoal. Charcoal that has been formed
is mixed with starch adhesives, molasses and cow dung with concentrations of 5, 10, and 15%
and printed using a hydrolic press. The analysis results obtained, the value of water content
(0.0015%), ash content (0.0212%), volatile matter values (2.33824%), heating value (7.184 cal
/ g), combustion rate (46:52) and fixed carbon (98,0159%). Based on the results of the analysis,
the optimal value of making charcoal from cassava stem waste is found in cow dung adhesive.
