The aim of present study is to synthesize chitosan-TiO₂ nanocomposite for packaging and its ability to inactive Staphylococcus aureus. TiO₂ Degussa P25 were dispersed in chitosan matrix in order to produce film-forming solution. The samples were characterized by SEM, FTIR, tensile strength, antibacterial and biodegradable test. The tensile strength test results showed that Cs-0.1Ti was the best nanocomposite compared to other variations of TiO₂ addition. Whereas for the test of S. aureus bacteria showed that no more S. aureus bacteria were found in chitosan-TiO₂ nanocomposite after incubation for 24 hours. It indicated more effective use of nanocomposites by adding TiO₂ compared to without adding TiO₂. For biodegradation analysis, the addition of TiO₂ slows the nanocompostites degradation process, which is indicated by the less mass loss that occurs in Cs-0.5 Ti nanocomposite.
