      Abstract
      Salah satu cara untuk memperbaiki cita rasa yang pada teh Sargassum yaitu dengan dilakukannya proses fermentasi menjadi teh kombucha. Penelitian ini bertujuan untuk menentukan pengaruh lama waktu fermentasi dan jenis gula yang berbeda terhadap profil sensori kombucha Sargassum, serta karakteristik fisiko-kimia dan profil flavour pada perlakuan jenis gula dan lama fermentasi terbaik. Sampel kombucha Sargassum diberikan perlakuan dengan gula yang berbeda (sukrosa, sorbitol, dan steviol) dan lama waktu fermentasi selama 9 hari dengan waktu pengambilan sampel hari ke 0, 3, 5, 7, 9. Karakteristik kombucha Sargassum dapat dilihat dari parameter pH, alkohol, warna, total gula, dan uji sensori. Berdasarkan uji sensori hedonik sampel terbaik kombucha Sargassum yaitu kombucha Sargassum dengan perlakuan gula steviol dan waktu fermentasi selama 3 hari. Profil flavour sensori kombucha Sargassum dapat dilihat dengan pengujian CATA dan GC-MS. Sampel kombucha Sargassum terbaik memiliki profil senyawa volatil dari golongan asam, alkohol, keton, heterosiklik dan lainnya.
       
      One way to improve the taste of Sargassum tea is by fermenting it into kombucha tea. This research aims to determine the effect of fermentation time and different types of sugar on the sensory profile of Sargassum kombucha, as well as the physico-chemical characteristics and flavor profile of the best type of sugar and fermentation time. Sargassum kombucha samples were treated with different sugars (sucrose, sorbitol, and steviol) and a long fermentation time of 9 days with sampling times of days 0, 3, 5, 7, 9. The characteristics of kombucha Sargassum can be seen from the parameters of pH, alcohol, color, total sugar, and sensory tests. Based on the hedonic sensory test, the best sample of Sargassum kombucha was Sargassum kombucha with steviol sugar treatment and fermentation time for 3 days. The sensory flavor profile of Sargassum kombucha can be displayed by CATA and GC-MS testing. The best Sargassum kombucha samples had a volatile compound profiles from acids, alcohols, ketones, heterocyclics and other groups.
