The Lidisari Team, led by Adhystira Raihannoeza Almadiva from the Bachelor of Data Science study program, and consisting of Bima Adhi Nugraha and Mario Firdaus Abdillah, both from the Bachelor of Informatics study program, carried out a project in Pliken Village, known as the center of tempeh production in Banyumas Regency. They developed a tool for processing waste, in collaboration with their partner, Mr. Imam Sudrajat, one of the owners of a tempeh production house in Pliken Village. With guidance from Mr. Dasril Aldo, S.Kom., M.Kom., the team successfully obtained funding in the Innovilage 2024 event held by Telkom Indonesia together with Telkom University.
The process of making tempeh from soybeans produces waste in liquid and solid forms. This waste can cause unpleasant odors. Furthermore, soybean waste also has the potential to pollute water because its content can reduce oxygen levels and increase acidity levels.
The Lidisari Team developed the Ecosoy project as a solution to overcome these problems. This project utilizes filtration technology and the Internet of Things (IoT). Filtration is carried out through an electrolysis process on the waste so that the waste pH can be raised to reach pH 7. The device is also connected to a smartphone via an application that displays data from various sensors within the tool. With this system, tempeh producers can more easily monitor the condition of the tool and the waste being processed.
The design and testing of the device yielded satisfactory results, leading the Lidisari Team to decide to develop a device that could be used directly at the tempeh production site. However, during the waste filtration process, the Lidisari Team faced constraints because the electricity requirement exceeded the capacity that could be generated by the existing solar panels. In the filtration process, the required electrical power reached 30 kWh, an unreasonable amount because it was too large. Furthermore, the problem they faced was that waste stored for too long caused the growth of fungi and microbes, thus hindering the neutralization process.
The Lidisari Team successfully found solutions to both problems by readjusting the standard acidity level of the waste and creating ventilation holes that function to eliminate unpleasant odors. This ventilation was designed to flow air to a sufficiently high space so that the smell does not disturb the activities of the surrounding community.
As the final stage of the Ecosoy project development, the Lidisari Team held a device handover event to the tempeh production house owned by Mr. Imam Sudrajat. With the presence of this tool, it is hoped that tempeh production in Pilken Village will become more environmentally friendly and can inspire other tempeh producers to do the same.
