Nowadays, biocomposite polymers are widely used in daily life based on their ability which is compossible, recyclable and sustainable. This paper presents biocomposite film's characterisation with different concentrations of nanocrystalline cellulose(NCC) (0 wt.%, 0.5 wt.%, 1.0 wt.% and 1.5 wt.%). Several techniques were used to review biocomposite film's characterisation, such as X-ray diffraction (XRD), Fourier transformed infrared spectra (FTIR) and biodegradable test. In the XRD study, the reinforcement PLA with NCC shows the improvement of crystallinity from 43.00% to 46.09% and decrease to 45.87% due to agglomeration of excessive NCC. FTIR shows the same chemical structure for each samples. As a result of the biodegradable test, the increasing concentration of NCC in the PLA increased the percentage of weight loss. Sample with NCC 1.5 wt.% shows the highest weight loss value (6.223%) compared to neat PLA (3.646%). Hence, PLA reinforced with nanocrystalline cellulose shows high potential and practical implementation as a biomaterial commercial application.
