Abstract—The objective of this research is to investigate the effect of teak leaf extract as antibacterial to the quality and antibacterial activity of active packaging edible film. This research is arranged used Randomized Block Design consists of 2 factor combinations. First factor is carrageenan concentration consist of 3, 5 and 7% of tapioca’s weight. Second factor is teak leaf extract’s concentrations consist of 10, 15 and 20% of edible film’s solution’s volume and repeated 3 times. The data were analyzed with ANOVA and continued with BNT or DMRT α=5%. The best treatment was determined using Multiple Atribute Method. The result showed that the addition of 7% carrageenan and 20% teak leaf extract was the best treatment. The edible film produced had 0,183 mm thickness, 11,635 gram/m2, 24hour water vapor transmission, 54,334 % elongation, 1,034 N/cm2 tensile strength and 0,600 cm and 0,650 cm antibacterial activity toward E. coli and S. aureus, respectively.
