Telang flower has the potential to inhibit the growth of Candida albicans, Malasezia furfur, Pitosporum ovale, and Aspergilus fumigatus through the kombucha fermentation biotechnology method. The purpose of this study was to determine the antifungal activity of telang flower kombucha at various concentrations of white sugar. The varying concentrations of granulated sugar used in this study were 20%, 30%, and 40% (w/v), each repeated 3 times. The positive control used was kombucha made from green tea. The negative control used was sterile distilled water. The well diffusion method is one of the methods used to test antifungal activity. The fementation of telang flower kombucha has overall antifungal activity. White sugar concentration of 40% kombucha telang flower was the best concentration in inhibiting the growth of fungi as a whole when compared to the concentration of white sugar kombucha telang flower of 20%, 30% and positive and negative controls.

Telang flower (Clitoria ternatea L.) is a plant that has long been used in medicine and has been shown to have antibacterial activity. This study aims to determine and test the antibacterial activity against S. epidermidis bacteria. This research method uses laboratory experiments conducted in vitro. The liquid body wash formulation of C. ternatea L. flower ethanol extract was made with various concentrations, namely 10%, 15% and 20%. The liquid body wash preparation was tested for its antibacterial activity against S. epidermidis bacteria using the disc diffusion method. The working procedure includes extraction, preparation of liquid body wash preparations, evaluation of preparations and testing of antibacterial activity of liquid body wash preparations of C. ternatea L flower ethanol extract. The results showed that C. ternatea L. flower ethanol extract had inhibitory zone activity against S. epidermidis bacteria. at each concentration, namely 10% of 3.33 mm, 15% of 3.8 mm and 20% of 6.13 mm. Meanwhile, the results of the evaluation of the preparations of all liquid body wash formulations of C. ternatea L. flower ethanol extract met the standards.

Telang flower kombucha is a probiotic that has the potential to be developed as a functional drink and even an active cosmetic ingredient in the form of hand soap as an effort to break the chain of transmission of COVID-19 and its mutations. The purpose of this activity is to provide additional insight to students, especially in the pharmaceutical study program at the Faculty of Health Pharmacy, Mathla'ul Anwar University, Banten, in utilizing the fermented kombucha solution of telang flower as an active ingredient in environmentally friendly hand soap cosmetics. The results of the activity showed that the service participants had increased knowledge or insight about the importance of using conventional biotechnology products as a new breakthrough in the pharmaceutical field. This can be seen from the increase in the pre-test and post-test which have been conveyed a lot during material exposure during pharmaceutical biotechnology lectures and during training. Participants who have attended training on making probiotic handwashing soap from fermented kombucha flower telang solution are more enthusiastic and understand the importance of the benefits of fermenting kombucha flower telang not only in the functional food sector but also in the potential for environmentally friendly cosmetics.
