Abstract
Briquettes can be used as an alternative fuel to replace fuel oil.The method of making briquettes can be done in several ways, one of which is using the hydraulic system compression force method.The physical characteristics resulting from this method have advantages and disadvantages.Therefore, this study aims to analyses the physical characteristics of coconut shell briquettes using tapioca flour as an adhesive.The process of making briquettes was done by compression force.Parameters observed were hardness and briquette flame.The results showed that the higher the compression force, the higher the hardness of the briquettes and the flame was also very good.The best coconut shell briquettes are found in a compression force of 12 kg/cm 2 with a hardness of 27.7 kg/cm 2 and a flame of 112.61 minutes.While the worst quality was obtained at a compression force of 4 kg/cm 2 with a hardness of 16.5 kg/cm 2 and a flame of 111.34 minutes.The development of the method of making briquettes still needs to be developed as a cheap alternative energy source.
