Ash content of candlenut shell charcoal produced by candlenut shell carbonization tool using a vertical multi chambers

Abstract

Abstract Candlenut shell, as one of biomass that has not optimally utilized, can be converted into charcoal which potentially increase its value. Candlenut shell carbonization tool using a vertical multi chambers is a tool that designed to convert candlenut shell into charcoal. The quality of the resulted charcoal remains unknown. This research aims to identify one of the quality variable of the charcoal which is ash content. The method used in the research was Gravimetric Analysis. Three samples from each carbonization chamber were taken to be analysed. As the tool has three carbonization chambers, the samples are 9 in total. The result showed that every chambers has different amount of ash content which are 2.167 % in CCI, 1.020 % in CC II and 4.687 % in CC III. In average, the ash content in candlenut charcoal resulted from Candlenut shell carbonization tool using a vertical multi chambers is 2.624 %. Hence, the tool managed to meet the SNI charcoal quality requirement in term of ash content which may not exceed 6 %.
