Sugarcane Bagasse as industrial waste contains 50% cellulose that can be synthesized into nanocellulose for applications in various fields such as face mask. Face mask was made by synthesizing nanocellulose from sugarcane bagasse with acid hydrolysis method. The hydrogel was synthesized from nanocellulose, alginate, and chitosan. The morphology of nanocellulose is in the form fiber with the size of 20-50 nm. The degree of swelling of Chitosan (CH), Nanocellulose-Chitosan (CN-CH), Alginate (AG), and Nanocellulose-Alginate (CN-AG) hydrogel samples were 81.56%, 82.25%, 63.69%, and 18.69%, and has a water contact angle 59.3o, 46.2o, 15.2o, and 24.9o, respectively. SEM characterization showed no pores on the surface on the hydrogel sample film. In conclusion, nanocellulose-chitosan hydrogel film is hydrophilic, with high degree of swelling, and no pores on the surface, and suitable for production of face masks.
