Antioxidants are essential for the body to overcome and prevent oxidative stress. Oxidative stress also plays an important role in the pathophysiology of aging and various degenerative diseases. This study aims to develop functional food products as a source of antioxidants in the form of herbal drinks dipped in snake fruit skin powder and red ginger. The experimental design used was a Completely Randomized Design (CRD). Determination of the formulation of herbal drinks with a ratio (Snake fruit skin: Red ginger) namely P1 (1:9), P2 (3:7), P3 (5:5), P4 (7:3), P5 (9:1) and was repeated five times. Based on the results of the study, it showed a significant difference (P <0.05) in the antioxidant activity of herbal drinks in each treatment with the highest activity in P5 (9:1) which was 43.56% and the lowest antioxidant activity in P1 (1:9) which was 27.5%. Based on the results of the organoleptic test, the color produced was more dominant in the characteristics of chocolate and the panelists preferred the treatment that had the characteristics of brown color. In the aroma parameter, the treatment preferred by the panelists was P1 because it has a characteristic of a rather strong spicy aroma.
