Optimasi Penurunan Kadar Tanin Pada Minuman Herbal Kulit Pisang Raja Dengan Penambahan Karbon Aktif Menggunakan Response Surface Methodology

ABSTRACT
Banana peel waste remains underutilized. An alternative to maximize the processing of banana peel waste is to make food products that are useful as health drinks such as herbal drinks, but the main problem with herbal drinks is the bitter taste. Tannin, which causes the bitter taste in herbal drinks, can be reduced in raja banana peel herbal drinks by adding activated carbon. One method that can be used to optimize tannin reduction using activated carbon is response surface methodology (RSM). This study aims to optimize the reduction of tannin in raja banana peel herbal drinks using RSM. The optimization process was preceded by a literature review to determine the range of experimental points with the dependent variable being tannin. The literature review obtained experimental points with variations in activated carbon concentrations of 0.2, 0.85, 1.5 g, temperatures of 70, 75, 80°C, contact times of 40, 50, and 60 minutes. The optimization of tannin reduction was carried out using Box-Behnken design (BBD) and then analyzed using RSM. The optimum condition for tannin reduction in the raja banana peel herbal drink obtained by RSM verification was by adding 1.198 g of activated carbon, 80°C temperature and 51.670 minutes contact time, resulting in a tannin concentration of 91.8567 μg/mL and antioxidant activity with an IC50 value of 127.60 ppm. The results of the organoleptic tests (color, aroma, and taste) and lightness test showed that the variation of activated carbon addition, temperature, and contact time had no significant effect on the herbal drink.
