Abstract
Cocoa pod husk (CPH) is a lignocellulosic waste that can be processed for producing chemical compounds. It can be used antifungal active substances which have the potential to become promising biofungicide. The purpose of this study was to obtain active material of bio-oil and char from CPH pyrolysis as an antifungal. This research include CPH pyrolysis, compounds analysis of bio-oil and char using Gas Chromatography-Mass Spectrometry/Fourier transform infrared (GC-MS/FTIR) further testing effectiveness as antifungal with the Total Plate Count (TPC) method. The spectrogram of GC-MS shows content of major chemical compounds of bio-oil are 2-methoxy-phenol; 2,3-dimethyl-pyridine; 3-methyl-1,2-cyclopentanedione; 2,6-dimethoxy- phenol; 2-butanol; 5-hydroxy-2,7-dimethyl-4-octanone; maltol; 3,4-dihydroxyaceto-phenone; 3-methyl-phenol; 2-methoxy-5-methylphenol; 2,3-dimethyl-cyclohexanol. The FTIR spectrum of char shows vibration at functional groups O-H, C≡C, C=O and CH3. The concentration of bio-oil 30% (v/v) and char effectively inhibit 100% fungus like control + (synthetic fungicide). Therefore, it is very promising to be applied as biofungicide.
