Anti-microorganisms in the white ginger root have attracted attention to utilizing ginger's water extract (GW) and nanocellulose fiber (GNCF), especially for preparing the robust antimicrobial composite film. Moreover, the mechanical property of the film is also necessary to be considered so it would not be torn easily. This work aims to quantify the GW/poly (vinyl alcohol) (PVA) composite film mixed with Zinc Oxide (ZnO) and GNCF for a potential biomedical application. The film preparation was assisted with a sonicator with 600W power for 1 hour. The results show that the most robust performance belongs to the PVA/GW composite film. It had the highest value for tensile strength of 30.7 MPa, while the PVA/ZnO/GNCF/GW had the highest tensile modulus of 104 MPa. Moreover, the PVA/GW/ZnO/GNCF film also shows the most vigorous antimicrobial activity. This study promotes composite film, which has the potential for biomedical applications with good antimicrobial and high mechanical properties. © 2024 Author(s).
