The effect of composition of candlenut shell charcoal briquette mix with petung bamboo on briquettes performance

Briquettes are solid fuels produced through a compression process from biomass. It was discovered
during its development that it was still less effective when only one ingredient was used in the formation of
briquettes. As a result, it is necessary to combine charcoal briquettes rather than just one ingredient. The goal
of this study was to determine the time it took to light a fire, the calorific value, the ability to boil water, and
the thermal efficiency produced by a mixture of charcoal briquettes made from candlenut shell waste and
bamboo petting of various compositions. The research method used is an experimental method that involves
combining candlenut shell waste with petung bamboo in various compositions before testing chemical
properties, calorific value, and burning briquettes in a biomass stove to obtain thermal efficiency values. The
results revealed that the best mixture of candlenut shell charcoal briquettes and petung bamboo with various
compositions was obtained in B4 briquettes (a mixture of 60% candlenut shell charcoal briquettes, 20% petung
bamboo, and 20% additives) with an ignition time of 95 minutes, the calorific value is 5321 calories per gram,
the capacity to boil water is 9 liters, and the maximum efficiency is 54.78 percent.
