Abstract

In this study the characteristic of humic acid extracted from solid state fermentation of oil palm empty fruit bunch EFB with cellulolytic fungi Trichoderma viride were compared with humic acid extracted from chrysanthemum compost. Since the functionality of humic acid depends on their structural composition the following method have been applied to characterize the humic acid fraction; elemental analysis performed by Scanning Electron Microscopy SEM with integrated Energy Disperse Spectroscopy EDS detector and by Fourier Transform Infrared FT-IR spectroscopy. The elemental analysis from EDS showed the humic acid extracted from solid fermentation of EFB consist of 53.5 carbon 4.0 nitrogen and 25.9 oxygen and the humic acid extracted from chrysanthemum compost consist of 54.4 carbon 2.4 nitrogen and 24.4 oxygen. From FT-IR analysis of both humic acid extracted from solid fermentation of EFB and chrysanthemum compost dominant band indicating O-H stretching 3432cm- for EFB and 3431cm- for chrysanthemum aliphatic vibration of methylene peak 2928cm- for EFB and 2930cm- for chrysanthemum aromatic with endo double bond CC stretching vibration 1647cm- for EFB and 1638cm- for chrysanthemum and a peak at 1053cm- obtained from both EFB and chrysanthemum were attributed for a primary structure of an alcohol.
