THE EFFECT OF AMYLUM ADHESIVE AND SAWDUST COMPOSITION FOR RUBBER SEED SHELL BIO-BRIQUETTE AS AN ENVIRONMENTALLY FRIENDLY ALTERNATIVE FUEL
Abstract
The purpose of this reaserch is to determine the optimum composition of rubber seed shell, sawdust,
and amylum adhesive. Experiments were carried out in several stages: aggregate of the raw materials,
drain the raw materials, do carbonization or combustion with 600°C temperature for 2 hours, restrict the
supply of oxygen so that the materials do not burn to ashes, sieve the materials, weigh each of
ingredients in the ratio of 60:20:20, 50:20:30, 40:20:40, and 30:20:50, blend the materials, print the
briquettes, drain, and analyze the contents of briquette. This reasearch generates optimum
compositionwith ratioof 60% rubber seed shells, 20% sawdust and 2 % amylum adhesive. It is in terms
of the parameters that have been analyzed in the form of spesification of inherent moisture is 4.99%,
ash content is 4.38%, volatile matter content is 24.75%, fixed carbon is 66.38% and calorific value is
6069 cal/gr.
