KAJIAN LITERATUR PERBEDAAN PELARUT EKSTRAKSI DAN VARIETAS KULIT PISANG TERHADAP AKTIVITAS ANTIOKSIDAN METODE RSA DPPH

Banana peel is an agricultural waste that has potential as a source of natural antioxidant compounds because it contains phytochemicals which are antioxidant components. The content of antioxidant compounds needs to be maximized by selecting the right solvent in the maceration method extraction process. The purpose of this study was to identify differences in extraction solvents and banana varieties on the antioxidant activity of RSA DPPH method. This research was conducted using SLR (systematic literature review) method with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach. The results showed that banana peels contain bioactive compounds including flavonoids, phenolics, tannins, triterpenoids, and steroids, all of which contribute to antioxidant activity. Of the five extraction solvents used, ethanol solvent yielded the highest antioxidant activity of 70.244% with a strong category and is the most effective and safe solvent (food grade) in extracting antioxidant compounds for food products. Among the banana varieties studied, kepok banana peel with 96% ethanol solvent showed the highest antioxidant activity with IC50 value reaching 9.702 1 ppm, which is in the very strong antioxidant category. This provides a wide potential to be developed as a functional ingredient as well as a strategic step to reduce agricultural waste and improve local food security.
