Tofu Liquid Waste Filter gets gold in I2ASPO 2021


Solo, IO — Four students of Universitas Sebelas Maret (UNS) Solo: Rakel Junetty and Fatata A’izza Rosyada (Mathematics Program from Mathematics and Natural Science “Fakultas Matematika dan Ilmu Pengetahuan Alam-FMIPA”), Millenia Trias Puspa Rukmi (Chemistry Program FMIPA), and Dji Hanafit (Mechanical Engineering Program Faculty of Teacher Training and Education (FKIP), created “Green-Ma” (Utilization of biofilter and manganese greensand for tofu wastewater filtration), a tool that filters out liquid waste of tofu production before being discharged into a river.

The team won a gold medal in the Indonesia International Applied Science Project Olympiad (I2ASPO) 2021, held by the Indonesian Young Scientists Association (IYSA). The competition was participated in by students from 14 countries and juries from national and foreign institutions. UNS Team also won the Special Award from Yayasan Prestasi Pendidik Indonesia (YPPI) (“Indonesian Educator Achievement Foundation”) at a medal awarding ceremony held in Surabaya last month.

The tool was developed based on their experience in a Student Community Service Program (KKN) environment that historically discharged wastewater from tofu production directly to a river, despite its toxic content. “We are concerned about social conditions in our KKN area,” Rakel Junetty – representing her teammates – stated, as quoted by Mipa.uns.ac.id, Monday (2/1/2021).

The team went through several stages of the competition before entering the “Invention Talk” stage: a paper submission, poster and PPT submission stage, along with registration for invention talk. They were grateful to pass the selection process and being able to present their works in the invention talk.

“My team and I were grateful for this achievement and, of course, delighted because this is my first offline competition during the pandemic. We hope that this work we are researching could continue developing and benefit the industry of tofu production in general,” Rakel explained.

The team participated in the competition to expand their relations and experience, because it was an international event participated in by 14 countries and juries representing national and international institutions. The competition also adopted a convention method that was interesting to showcase works that could potentially be commercialized.

According to Rakel, the team was proportional because it had four members from three different programs that actively participated in the process. The tool design was prepared by Dji Hanafit, while testing of wastewater content was performed by Millenia Trias Puspa Rukmi, and tool and cost optimization were handled by Rakel and Fatata.
