Green Revolution In Kebondalem: Transforming Mung Beans Into Local Nutritional Gold

Kebondalem, Pemalang In order to implement the Thematic Real Work Lecture (KKN-T) programme of Team 163 Diponegoro University, student Amelia Syahrani from the Industrial Chemical Engineering Technology Study Programme, UNDIP Vocational School, has successfully carried out a multidisciplinary work programme with the theme “Tempe Product Diversification: Innovation of Green Mung Beans-Tapioca Tempe to Support Tempe Chips MSMEs Based on Local Nutrition” in Kebondalen Village, Pemalang District, Pemalang Regency.

Based on the advice of the Field Supervisor (DPL), Sri Risdhiyanti Nuswantari S.Tr.T., M.T., this programme is based on the concept of diversification of food products through a fermentation biotechnology approach by utilising alternative substrates. Conventional tempeh, which is generally made from soybean (Glycine max), was developed into an innovative product using mung beans (Vigna radiata) as the main substrate with the addition of tapioca (Manihot esculenta) as a binding agent and source of complex carbohydrates. Biochemically, the fermentation process by Rhizopus oligosporus mould on mung bean substrate produces a different essential amino acid profile compared to soybean tempeh, with high quality protein content reaching 20-23%. The addition of tapioca serves as a natural prebiotic that supports the growth of probiotic microorganisms, while improving the texture and shelf life of the product.

In this work program, Amelia conducted counseling on Thursday, 7 August 2025 using the audiovisual demonstration method through video tutorials on making mung bean-tapioca tempeh. Through the counselling activities, MSME players gained knowledge and technical skills in the diversification of tempe products, which are expected to increase economic added value and competitiveness of local products. “This multidisciplinary work programme has successfully integrated the industrial chemical engineering technology approach with community empowerment, creating innovative solutions for the development of MSMEs based on local potential,” said Dr. Ir. Falmi Arifan, S.T., M.Eng., M.M., IPM ASEAN Eng. Collaboration between students, supervisors, and MSME partners resulted in sustainable technology transfer to improve the economic welfare of the Kebondalem Village community.
