Effect of Pretreatment Process by Using Diluted Acid to Characteristic of oil Palm's Frond

One of lignocellulosic biomass feedstock, oil palm's frond is the raw material for a potential second-generation bio- ethanol production. Pretreatment process is an important process in series of process to produce bio-ethanol. This research aims to study the effect of pretreatment process by using diluted acid to oil palm's frond characterization as raw materials in the hydrolysis reaction producing monomer sugars which will be fermented into ethanol. The raw materials are characterized in term of specific surface area and surface morphology. Analysis results of the specific surface area by BET (Brunauer Emmett Teller) method showed that after pretreatment by using diluted acid, their specific surface area increasing from 2.23 m2/g to 5.57 m2/g, while the surface morphology of the images shown by Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) showed that there is changing the morphology of surface followed by the increasing of amorphous part.
