The use of commercial non-biodegradable materials is highly dependent on the availability of fossil oil sources and effect to the environment. The development of biocomposite materials is increasing to overcome these issues. Cellulose based biomaterial has been widely investigated and bacterial cellulose has high capability to produce biocompoitse due to high cellulose purity. This paper investigated yam bean (Pachyrhizus erosus L. Urban) as bacterial cellulose material for biocomposite matrix while bamboo microfibrillated cellulose (MFC) was used as the reinforcement agent. The objectives of this research were to determine optimum condition of bamboo MFC concentration and to characterize the modified biocomposite upon its mechanical (tensile strength), morphological (SEM), thermal (DSC and TGA) and structural (FTIR and XRD) properties. The results showed that optimum condition was achieved at 0.375 %-v/v of bamboo MFC with tensile strength of 22.41 ± 7.34 MPa. Furthermore, the biocomposite product had good thermal stability as evaluated by TGA analysis, while its glass transition temperature (Tg) attained at 75 °C which was lower than that of yam bean bacterial cellulose without the addition of MFC (115 °C).
