Abstract: Vibrio cholerae menghasilkan enterotoksin yang dapat menyebabkan penyakit kolera yaitu infeksi saluran pencernaan yang disebabkan oleh bakteri Vibrio cholerae. Kombucha teh hijau sebagai agen antibakteri yang dapat menjadi pilihan dalam upaya pengobatan infeksi yang disebabkan oleh Vibrio cholerae. Karakteristik dari kombucha teh hijau berperan penting dalam potensinya sebagai antibakteri terhadap Vibrio cholerae. Penelitain dilakukan dengan metode pengujian fermentasi, uji organoleptik dan difusi cakram. Karakteristik kombucha teh hijau yang terbentuk berwarna coklat muda, memiliki aroma harum dan rasa yang asam dengan pH 3. Kombucha teh hijau memiliki sifat antibakteri terhadap Vibrio cholerae dengan adanya pembentukan zona hambat sebesar 21,43 mm. Karakteristik kombuca teh hijau menunjukkan profil sensori yang khas, meliputi rasa asam, aroma harum yang cukup menyengat, dan warna coklat muda. Kombucha teh hijau mengandung metabolit sekunder yang berpotensi sebagai antibakteri dengan adanya zona bening yang terbentuk disekitar pertumbuhan bakteri Vibrio cholerae. Vibrio cholerae produces enterotoxins that can cause cholera, which is an infection of the digestive tract caused by the bacterium Vibrio cholerae. Green tea kombucha serves as an antibacterial agent that can be a potential option for the treatment of infections caused by Vibrio cholerae. The characteristics of green tea kombucha play an important role in its potential as an antibacterial against Vibrio cholerae. The research was conducted using fermentation testing methods, organoleptic tests, and disk diffusion. The characteristics of the formed green tea kombucha are light brown in color, have a fragrant aroma, and a sour taste with a pH of 3. Green tea kombucha exhibits antibacterial properties against Vibrio cholerae, as evidenced by the formation of an inhibition zone measuring 21.43 mm. The characteristics of green tea kombucha show a distinctive sensory profile, including a sour taste, a quite pungent fragrant aroma, and a light brown color. Green tea kombucha contains secondary metabolites that have the potential to act as antibacterial agents, as indicated by the clear zone formed around the growth of the bacterium Vibrio cholerae.
