Abstract

Coconut shell charcoals haven’t been used maximally by people in Bandarharjo whereas it can be utilized as activated charcoal, briquettes, etc which can increase its economic value. Previous research has not been able to answer the problem about the optimal size of charcoal particles and type of adhesive to get the briquettes which have a calorific value and durability of the best. The objective of this research is to study the optimal particle size, the best type of adhesive, the optimal concentration of adhesive, and briquette maker equipment design. Variables used in this research are type of adhesive (tapioca flour, wheat flour, molasses, and silicate), concentration of selected adhesive (10%, 15%, 20%), and sieve size (20 mesh, 30mesh, 40mesh). The parameters used are the calorific value that measured by Boom calorimeter, the stability of briquettes, and briquettes hardness tested shatter index method. Result shows that tapioca flour is the best type of adhesive as compared with 3 other gluten (wheat flour, molasses, and silicate). The highest calorific value of 6748.69 cal / g obtained in 20% of adhesive with a size 20 mesh coconut shell charcoal. According to the shatter index test, the best briquette hardness is obtained on a variable 20% adhesive with 40 mesh particle size because the particles lose only 0.11%.
