Abstrakt: This study aims to determine the characteristics of biochar from the pyrolysis of solid waste hydrodistillation of cardamom fruit oil. Pyrolysis temperature conditions 250-450°C for 1 h. At a temperature of 450°C, the optimum conditions for biochar from cardamom seeds and husk yields 38.55 wt.% and 34.27 wt.%, water content of 5.72 wt.% and 8.7 wt.%, respectively. The calorific value of seed and husk biochar was 6201.15 cal/g and 4343.19 cal/g. The results of the CHN test showed significant changes after pyrolysis of cardamom seeds and husk, where C content was 64.43 wt.% and 48.94 wt.%, H content was 3.98 wt.% and 2.97 wt.%, and N was 2.96 wt.% and 1.29 wt. %. The FTIR analysis resulted in a new peak in the wavelength range of 1919 cm−1 to 2170 cm−1 (the functional group of organic compounds C≡C (alkynes)). From SEM-EDX, it was observed very significant differences were obtained at 1500 x magnification for cardamom seeds (C changed from 62.73 wt.% to 67.10 wt.%) and husk (C changed from 48.25 wt. % to 68.18 wt.%) waste biochar. From these results, the carbon content is abundant which is the active side of biochar, which allows cardamom waste biochar to be applied as bio briquettes. [ABSTRACT FROM AUTHOR]
