Abstract :
Recently, the need and consumtion of energy just depend on using
petroleum energy which is a non-renewable fuel. On the other hand, there is a big
quantity of biomass energy which is quite abundant that has not been optimized.
One of the utilization a biomass energy is production of briquettes. The aim of this
research is to identify the effects of compotition of a mixture briquette from
bamboo waste and rice husk on the heating value, moisture content, ash content,
and briquette combustion rate.
This study used an experimental method by mixing bamboo waste charcoal
and rice husk with a compotition 85:15 (%), 80:20 (%), 75:25 (%), 70:30 (%),
using tapioca flour adhesive as 7%, and the briquette weight of 20 gram.
The result of the research showed that each addition to the compotition of
rice husk charcoal decreased of moisture content, heating value, briquette
combustion rate, and increased an ash content. All the tests have met the quality
standarts of the briquettes used, except for the ash content value, with the best
result in the A1 (85 % bamboo waste charcoal and 15 % rice husk charcoal)
variation, with the heating value of 6233,912 cal/gr, moisture content of 3,76 %,
ash content of 12,16 %, and combustion rate of 0,026789 gr/min
