UNS — Waste remains an unresolved scourge for the community and government; innovations in waste management are needed to reduce its negative impact. Recently a group of Universitas Sebelas Maret (UNS) Surakarta Student Community Service Program (KKN) in Bendan Village, Banyudono Sub-District, Boyolali, attempts to transform waste from tofu/tahu industry into fertilizers and biogas, Tuesday (16/2/2021). In total 30 residents are attending the event at Bendan Village Meeting Hall. Before practicing the process, the Group 10 of the KKN UNS Team held dissemination on fertilizers and biogas production as an introduction.

Tofu or tahu (bean curd) has become a commercial commodity in Bendan Village, resulting in a significant amount of waste. “In this KKN program, we bring ‘Creative Industry’ theme, where it still related with waste management. Therefore, we choose tahu waste utilization,” explains Arfais Rahman as the Head of the KKN team.

The student of Office Administration Education Study Program, Faculty of Teacher Training and Education (FKIP) UNS explains that they collaborate with the Environment Service Agency (DLH) of Boyolali District and Agni Mandiri Group. “We collaborate with the related government agencies and the Agni Mandiri Group, which focused on waste management in Boyolali. Thus, all activities from dissemination to the processing practice, we are assisted by the group,” he added.

The practice was given to clear up the material presented by DLH Boyolali and Agni Mandiri Group. The practice focus on fertilizers made from waste material. Aside from the materials and tools that are easy to use, the process can be done quickly and efficiently.

“The materials are tahu/tofu waste (150 liters), brown sugar (4 kg), water (5 liters), activator solutions (1 liter), a barrel with 200 liters volume, and mixer. The process started with mixing all materials in the barrel and then left it alone for about 15 days. After 15 days, the fertilizers can be applied directly,” he explains.

Arfais hopes that this activity can increase community awareness toward waste management, especially tahu waste. He emphasized that the existing waste problem become a collective responsibility. Humas UNS
