N2 - Microfibre cellulose (MFC) is one of trending topics in advanced material researches. This work was aimed to study the characteristics of MFC produced from waste sorghum stem. To produce MFC, the amorphous part presence in the fibre such as hemicellulose and lignin had to be removed through chemical process. This study compared two methods for preparing the waste sorghum stem i.e. 1) Alkalization 1-Hydrolysis-Alkalization 2-Acetylation and 2) Alkalization-Bleaching-Acetylation. Thermal stability, crystallinity, morphology, and functional group analysis were the parameters measured in this research. The method that produce MFC with better quality was the first method. The MFC had a significant reduction of amorphous fraction with crystallinity index of 81.07%. From STA analysis it was found that the MFC product was able to endure the thermal treatment at 315°C without any significant weight loss.
