Abstract

This study aims to characterize the pyrolysis products of cocoa pod waste from North Kolaka Regency, Southeast Sulawesi Province. Pyrolysis takes place at various temperatures between 112 - 512 oC and produces liquid smoke and charcoal products. The highest liquid smoke yield was obtained at a temperature of 212 oC of 20.05%. The results of GC-MS analysis showed that liquid smoke contains many potential compounds consisting of acetic acid compounds with the highest concentration of 28.1%, Phenol, 2-methoxy- (CAS) Guaiacol with the highest concentration of 4.18%, 3-Hexine-2,5-diol (CAS) Hexine-3-diol-2,5 of 2.94%, and several aromatic and alcohol compound groups. FTIR analysis shows that the typical functional groups of cocoa pod charcoal consist of OH (hydroxyl) and C = C-H (aromatic) groups. XRD analysis shows that charcoal is dominated by an amorphous phase with a degree of crystallinity of 14%. Liquid smoke and cocoa pod charcoal have the potential to be used as raw materials in the chemical, health and manufacturing industries.
