The Processing of Coconut Shell Based on Pyrolysis Technology to Produce Reneweable Energy Sources

This study is an experimental study that aims to make coconut shell charcoal briquettes which have reliably characteristics or qualities. This study includes drying of raw materials, composing, grinding and sifting, mixing the adhesive, printing and compression, drying, and determination of characteristics include density, ash content, duration of combustion and calorific value. The result of the study showed that in general there is no significant difference between the characteristics of the briquettes using a starch adhesive with one that use sago starch adhesive. The characteristics of briquettes that were produced are in accordance with the standard in Indonesia, the United States and Japan, except Britain which give very strict standards. Activated charcoal from coconut shell charcoal that was activated with 1M HCl has metal adsopsi power Cr (VI) that is quite high (up to 22.15%).Keywords: briquettes, coconut shells, gluten, calorific value, tapioca, sago, ash, density
