Abstract:
Coconut shell aromatherapy charcoal briquettes with the addition of local orange peel
powder and agarwood powder is an innovation to develop charcoal briquettes. The purpose
of the study was to analyze the proximate test which included moisture content, ash content,
volatile matter content, bound carbon content, heating value and density, knowing the best
treatment and organoleptic tests. Completely Randomized Design (CRD) method was used
for 5 treatments x 3 replications with 15 samples. The best water content is found in
treatment A (50% coconut shell + 50% agarwood powder) of 5.5067% and meets the ASTM
standard, which is a maximum water content of 6%, the best ash content is also found in
treatment A (50% coconut shell + 50 % gaharu sawdust) of 3.0600% and all treatments
entered the ASTM standard max 8%. The best value for volatile matter content of 54.9700
was obtained in treatment C (50% coconut shell + 30% agarwood powder + 20% local
orange peel powder) and for the bound carbon content the best value was found in treatment
C worth 34.3933%, all treatment of volatile matter content and bound carbon content did not
meet ASTM standards, namely for volatile matter content of 19 sd 28% and 60% bound
carbon content. Treatment A showed the best calorific value of 5043.3267 cal/g, but did not
meet the ASTM standard of 6500 cal/g. All treatments for density have not been included in
the ASTM standard with a standard value of 1 gr/cm3
, the best density is in treatment E (50%
coconut shell + 50% local orange peel powder). The results of the organoleptic test showed
that from 5 respondents who were selected said that treatment A (50% coconut shell + 50%
agarwood powder) began to smell aromatherapy at 30 seconds of burning charcoal
briquettes with long ignition of briquettes to ashes for 26 minutes.
