Banana is one of the most consumed food commodities in the world. People consume fruit flesh and remove peel as wastes. Banana peels contain starch, pectin, and phytochemical compounds such as phenolic and flavonoids that act as natural antioxidants. This study aimed to determine the antioxidant activity of Kepok Kuning banana peel extract (Musa paradisiaca L.) and Cavendish (Musa acuminata Colla, AAA), and its potential as a preservative of chicken meat. The dried banana peel was extracted using 80 % methanol. Kepok crude extract (KCE), cavendish crude extract (CCE) were evaluated for their antioxidant activity using DPPH and FRAP methods. BHT was used as a synthetic preservative control. Both extract KCE, CCE, and control BHT were tested for their preservatives potency for chicken meat. Three controls were meat without treatment, meat  2% salt and positive control meat  BHT 0.1%  2% salt. Whereas the treatments included meat + EKK + salt 2% and meat + EKC + salt 2%, both at concentrations of 5%, 10%, and 15%, respectively. The parameters observed were changes in the color of the meat for eight days incubation in the refrigerator. It was observed with ImageJ software while free fatty acid (FFA) contents were determined by titration. The results showed that both EKK 15% and EKC 15% showed higher antioxidant activity than 0.1% BHT. There was no significant difference between treatments on the L (lightness) and b (yellowness) values, but not for a (redness). FFA values were significantly different between treatments with the highest value in the untreated control at 0.41% and the lowest at 0.12% for the EKK 15 % and EKC 15%. These results indicate that both banana peel extracts have the potential to be developed as preservatives of chicken meat.
