Abstract

Limau Manis Village as Kampung Manggis is supported by the production of mangosteen in Padang City which is number 2 (two) in West Sumatra and 80% of mangosteen in Padang City comes from Pauh Subdistrict, with the center being in Limau Manis Village and the existence of Kampung Manggis brings hope for the community to improve their economy and will have an impact on the economy of the Padang City community. The skin of mangosteen fruit can be processed into value-added products. However, farmers and local businesses still face several challenges, such as the lack of knowledge and technology to process mangosteen peels into economically valuable products. Abundant mangosteen peels during the harvest season are often discarded or burned, causing environmental impacts such as soil and air pollution. However, due to the lack of public knowledge on mangosteen peel processing as waste, an innovative solution is needed to turn mangosteen peel waste into a new source of income through the development of competitive derivative products. This community service activity is designed as a strategic step to empower the community, optimize local potential, and build an innovative, sustainable mangosteen agroindustry, creating value-added products and improving the economic welfare of the community. In addition, this activity is also expected to be a model of agroindustry development based on local potential that can be developed. The purpose of this community service activity is to provide training in improving the knowledge, skills of the community in processing mangosteen skin, increasing the added value of mangosteen skin into mangosteen skin tea and mangosteen skin syrup products that have a broad impact on economic, social and environmental improvement.

Abstract

Sago liquid waste contains high levels of carbohydrates and has potential as a fermentation medium for bacterial cellulose production. However, its nutritional content requires enhancement by supplementing it with tea waste to achieve optimal yields. This study investigated the effect of varying tea waste additions on the characteristics of bacterial cellulose produced from kombucha fermentation based on sago liquid waste. The research method used a completely randomized design with five treatments (2, 4, 6, 8, and 10 g of tea dregs) and three replications. The observed parameters included yield, thickness, moisture content, cellulose content, and Fourier Transform Infrared (FTIR) spectroscopy. The results showed that increasing tea waste levels significantly affected all parameters (p < 0.05). The best treatment (10 g) resulted in a yield of 18.21%, a thickness of 13.47 mm, a moisture content of 47.57%, and a cellulose content of 52.43%. FTIR spectral analysis confirmed the characteristic peaks of bacterial cellulose, indicating the presence of crystalline β-1,4-glucan structures. The identification of cellulose type I is significant because it represents the native crystalline form of bacterial cellulose, which is associated with high mechanical stability, strong hydrogen bonding, and potential suitability for biopolymer applications. This study demonstrates that tea waste is an effective nutrient supplement that enhances the quality and quantity of bacterial cellulose derived from kombucha fermentation of sago liquid waste.
