It is believed that there are still many untapped benefits from this plant. This study was conducted to determine the effectiveness of D. serrata fruit extract as an antimicrobial that causes disease in humans, and to determine its effectiveness as an antioxidant. The antioxidant test was carried out using the DPPH method while the antimicrobial test was carried out by the agar diffusion method (Kirby-Bauer). The ripe Dillenia fruit was extracted using methanol, the extract was then diluted in various concentrations for the DPPH test The results showed that the D. serrata extract had the ability as an antioxidant. The antioxidant activity of fresh fruit extracts was higher than that of dried fruit extracts.
