These groups have been reported that have potential as antioxidant, antimicrobial, etc. Methanol extract from dahlia were assayed for antibacterial activity by agar diffusion method. Methanol exfract at 10% concenfration (w/v) in ethanol absolute showed antibacterial activities, against Bacillus subtilis, Staphilococcus aureus and Escherichia coli. Strength of antibacterial activity for flower extract from dahlia were showed by Du Bandung againts Bacillus subtilis (15 mm), D? Bandung and Dii Berastagi againts Staphilococcus aureus (15 nmi), and D19 Malang againts Escherichia coli (15 mm).Dahlia variabilisantibacterial activityagar diffusion methodUR e-Research
