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.
