: This study aimed to find out the antibacterial and effective concentration of pomegranate leaf extract toward Escherichia coli and the validity of movie media in learning materials. This research consisted of two phases. First, the examination was conducted using antibacterial power experiment with six treatments and five repetition which were analyzed with ANOVA on RAL models. The findings showed pomegranate leaf extract had natural antibacterial power against E. coli. It was indicated by the formation of a transparent zone around the paper disc and 50% effective concentration. Second, examining of movie media validity using descriptive method which was validated by five validators and analyzed based on the average score for all aspects. The results of movie media validation analysis obtained an average score 3.6 (it classified as valid) and appropriate to be used in learning process on the role of bacterial material for tenth grade students
