As many as five students of Thursina International Islamic Boarding School achieved proudly a silver medal in the 2025 Global Youth Invention and Innovation Fair (GYIIF). The competition has witnessed their innovation in the field of natural beauty based on organic waste. The team consisting of Muhammad Dhonan Chilmi, M. Azzam Fahim A, Evan Dhaqii Afta, Azka Hafianto, and M. Zaiyan Al Ghozi, carried out a study entitled Sunbynana: Exploring Natural Beauty Through Organic Banana Peels Waste for Moisturizing Facial Sheet Mask. The product utilizes banana peels as the main ingredient in producing natural moisturizing facial mask.

The research is based on the increasing awareness of the importance of environmentally friendly and natural skincare products. Banana peels, which are generally considered waste, actually contain active compounds such as tannins, flavonoids, and triterpenoids that have the potential to provide moisture and nutrition for facial skin.

"Banana peels contain various active compounds that are beneficial for the skin, especially in moisturizing and maintaining healthy facial skin naturally," said Muhammad Dhonan Chilmi, a member of the research team.

Furthermore, he explained that the research aims to optimize the use of banana peels through the extraction of its active ingredients, the formulation of an effective facial mask, and testing its effectiveness in hydrating the skin.

"With the innovation, we hope to present an alternative beauty product that is more environmentally friendly while reducing organic waste that is simply thrown away," he added.

The success has proved that Thursina IIBS students are not only academically accomplished, but also able to develop innovative solutions, beneficial to society and environment. They hope the research would inspire other young people to  originate sustainable products.

"We hope the research will be the beginning of more organic waste-based innovations to offer real benefits for the environment and society," concluded Chilmi.
