One of the innovations of cascara is the kombucha cascara which is made from the fermented coffee fruit skin, which is fermented with a kombucha starter or Symbiotic Culture of Bacteria and Yeast (SCOBY). The cascara used in this study was cascara from the Timtim, Borbor, and Ateng super coffee varieties. This study aims to determine the effect of different varieties of arabica coffee and fermentation time on the quality of kombucha cascara. This study used a factorial randomized block design method consisting of two factors. The first factor is cascara from coffee varieties consisting of three levels (Timtim, Borbor, Ateng super). The second factor is the length of fermentation, consisting of three levels (4, 8, and 12 days). Parameters analyzed were antioxidant activity, total phenol, tannin content, pH, and total microbe. The results showed that cascara from coffee varieties significantly affected antioxidant activity, and pH. Fermentation time significantly affects antioxidant activity, total phenol, tannin content, pH, and total microbial. The best treatment was obtained in the cascara treatment of the Ateng super coffee variety and the fermentation time was 12 days with the following characteristics; antioxidant activity 45.74%, total phenol 132,59 mg/L, tannin content 0.46%, pH value 2.69, and total microbes 4.99x104 CFU/ml.
