The XRD spectra of the cocoa pod ash were examined before and after use. The XRD of the ash in Fig. according to shows the process of banding and that its usage as a catalyst does not cause a change on the structure of the cocoa pod husk. There is an indication of amorphous structure which is derived from lignin and hemicellulose content of the cocoa pod husk which also has amorphous structure. The peaks catalyst crystalline structure in Fig. shows that value 2θ angles exhibited between 10° -70° peaks. These values were ascribed to amorphous structure of carbon atoms and some fainted crystalline structures due to the presence of some bond structures between potassium and other compounds. The minor peak values 27.011°, 38.11°, and 60.11° indicate the presence of crystalline structure before use Fig. which may be associated with potassium bonded with inherent element of the catalyst as revealed by the SEM. After the catalyst has been used Fig. , there seems to be no significant change in the structure of the catalyst.
