The objective of this research was to study the experimental design for the
production of briquette solid fuel from oil palm fiber and kernel meal residue by Factorial
Design. Independent variables consisted of mixture ratio of oil palm fiber to oil palm
kernel meal residue, percent of coordinate volume and the briquette forming pressure
whereas the dependent variables were composed of compression resistance value, impact
resistance value and combustion rate. The results of the experimental design showed that
at 20 tons of forming pressure, the mixture ratio of kernel meal residue to oil palm fiber
80:20 and 20 percent of coordinate volume provided the best compression resistance value
of 2,636 Newton with 85.75% impact resistance value, combustion rate of 1.71
Grams/Minute, heating value of 4386.3 Calories/Gram and the density of 700
Kilograms/Cubic Meter.
