Nowadays, cellulose knowledge from natural plant is one of the major contributions to the new and advance product development since it has no harm to the environment. Microcrystalline cellulose (MCC) possesses the merits of cellulose which has a lots of potential to be used in all manufacturing areas and various studies on the isolation of MCC from different sources using various procedures was held in order to define its characterization so that the potential of MCC as fiber phase in composite will be beneficial to user. In this work, fibres from banana pseudostem appear as an interesting source for cellulose fiber due to its readily available in Malaysia. The aim of this project was to evaluate the effects of chemical treatments over structural modifications on the fibre by hydrolysis analysis and mechanical treatment. MCC were determined through fiber chemical reaction which involves alkali treatment, bleaching and acid hydrolysis treatment. Scanning micron electroscope (SEM) and X-ray diffraction analysis was used in order to see the morphology before and after the treatment. The results showed the highest crystallinity index is banana pseudostem treated with 60% H2SO4 concentration with 90 minutes concentration at value 79.53%. The addition of sulfuric acid concentration has given effect through the SEM image which is clearly seen that the fibers have raptured. Measurement on SEM and PSA images proved that the reduction of raw fibers was from 280.20μm to 58.16μm and 171.13μm respectively. This research specifies chemical treatment (hydrolysis process) is the main factor of cellulose presence meanwhile the mechanical treatment (sonication process) will catalyst the presence in terms of diameter size and surface morphology.
