AbstractThe potential amount of coconut sawdust biomass in Indonesia is very abundant, so far it has not been utilized optimally and tends to be wasted as waste. Coconut sawdust with the main composition of carbon contains heat equivalent to light coal, which is around 4400 kcal/kg. Even though its calorific value is still low, it has the potential to be used as a solid fuel source or an alternative energy source. The calorific value of coconut sawdust can be increased through the pyrolysis process. A study has been carried out on the effect of nitrogen inert gas flowing continuously into the pyrolysis reactor of coconut sawdust biomass waste (Cocos nucifera) on the calorific value of the resulting charcoal. The aim of the research is to determine the effect and optimum flow path of nitrogen inert gas which gives the maximum calorific value of charcoal product. From this study it was concluded that the continuous flow of inert nitrogen gas into the pyrolysis reactor had an effect on increasing the calorific value of the charcoal product by up to 4% compared to not using the inert gas. The optimum nitrogen gas flow rate is 2 L/minute giving a maximum effective calorific value of 7200 kcal/kg

This study aims to determine the effect of argon inert gas and pyrolysis time variations on the quality of charcoal produced from the pyrolysis of coconut sawdust waste. This research was carried out in a pyrolysis reactor operating at 400 oC, with an inert gas rate of 2 liters/minute with time variations of 60, 90, 120, 150, and 180 minutes. The results of the research obtained products in the form of charcoal and liquid smoke. Pyrolysis using inert gas has a heating value of 7229 kcal/kg. While the treatment without inert gas has a calorific value of 7050 Kcal/kg. This complies with SNI 1683-2021 concerning Wood Charcoal, which is a minimum of 6500 Kcal/kg. The optimum time obtained is 150 minutes with the characteristics of charcoal: (1) the volatile matter of 16.85% wt, (2) moisture of 2.47% wt, (3) ash content of 4.11% wt, and (4) fixed value carbon 76.57%wt.
