The Team of Biology students from Faculty of Biology Universitas Gadjah Mada collaborated with PT Pagilaran on the development of herbal tea made from the leaves of Aquilaria malaccensis, an agarwood species. This collaboration, conducted from March 2023 to November 2023, was part of the Independent Learning Independent Campus Program (MBKM). The team consists of Atikah Nurunnissa’, Damar Nirma Wati, and Listia Dewi Amaliawati, under the guidance of Drs. Tri Rini Nuringtyas, S.Si., M.Sc., and Tri Wahyuni, S.TP. from PT. Pagilaran.
The herbal tea development activities commenced with a discussion at the PT Pagilaran Kotabaru headquarters, located at Jl. Faridan M. Noto, No. 11, Kotabaru, Kec. Gondokusuman, Yogyakarta. Subsequently, the students visited the PT Pagilaran Samigaluh branch on 13-14 March 2023, focusing on the production of green and black tea. During the visit, the team were guided by Mr. Waridi through the entire tea-making process, starting from harvesting, withering, fermentation, to drying. Following the visit, the team formulated agarwood leaves with other ingredients to create various herbal tea blends: 1) Agarwood leaves, black tea, red ginger; 2) Agarwood leaves, green tea, lemon; and 3) Agarwood leaves, green tea, rosella. Each formulation had different concentrations, such as Agarwood leaves: Black tea / Green tea: Natural ingredients (1: 0.75: 0.25), (1: 0.75: 0.5), and (1: 0.75: 0.75). Subsequently, the students conducted organoleptic tests to determine the preferred formulation and concentration of herbal tea. They also performed extractions using 80% ethanol, followed by UV-Scanning to identify the compound profile of agarwood herbal tea with antioxidant, antidiabetic, and antiobesity activities.The UV-Scanning results and bioactivity analysis using PASS Online revealed that all three formulations possessed potential bioactivity, making them suitable for health-supporting beverages.
It is anticipated that this collaboration will provide valuable insights for the students throughout their research process, expanding possibilities for drug development from natural resources, particularly agarwood leaf extracts. This activity is expected to strengthen public understanding of Indonesia’s natural wealth and its potential in pharmaceutical development, inspiring the creation of innovative solutions to enhance human health and well-being.
