Bamboo species has widely used in many industries nowadays. The Gigantochloa albociliata (Buluh Madu) is chosen because of Malaysia’s fast-growing species, cheaper and plentiful. Gigantochloa albociliata has undergone a Kraft pulping process for cellulose, followed by an acidic hydrolysis process to process microcrystalline cellulose (MCC). In this study, MCC made from bamboo and the characteristic of MCC are described in this study. The MCC were analysed with FT-IR (Fourier transform infrared spectroscopy), B.E.T (Brunauer-Emmet Teller) and XRD (X-ray diffraction). The IR spectra shown the broad peak in the B-MCC (microcrystalline cellulose derived from bamboo) and C-MCC (commercialized microcrystalline cellulose) at range 3331 cm−1 to 3341 cm−1 was appointed and presented the functional group of hydroxy compounds, H-bonded and O-H stretch in the wavenumber of single bond region (2500 cm−1 to 4000 cm−1). Then, the specific surface area of particle size for B-MCC (microcrystalline cellulose derived from bamboo) is 0.019 m2/g, while for C-MCC (commercialized microcrystalline cellulose) is 0.0018 m2/g. Lastly, the crystallite size of B-MCC and C-MCC were 0.0163 and 5.5141 µm. The crystallite size of B-MCC was smaller than C-MCC. The smaller the size of the particle, the more value of the surface area of the particle. So, B-MCC can be one of the alternatives for the C-MCC due to the abundance of bamboo.
