UNDIP, Semarang (April 21) – Students from the Applied Bachelor’s Program in Industrial Chemical Engineering Technology (TRKI), Vocational School of Universitas Diponegoro (UNDIP), have once again made an outstanding mark on the international stage. At the Jakarta International Science Fair (JISF) 2025 Online Competition, held from April 15–17, 2025, two teams from UNDIP’s research community, Kayovoks Chem-E-Car, secured two gold medals in two different categories: Engineering and Environmental Science.
The first team, Kayovoks Ramayana, earned the gold medal in the engineering category with their project titled “Advancing Green Automotive Prototypes: Chemical Reaction-Driven Oxygen Generation and Pneumatic Propulsion.” This team—comprising Akhmad Surya Adi Maulana, Muhammad Zidan Fadilah, Devano Gothicardo, Rizki Ananda, Ilyas Nur Hidayat, and Hamaz Al-Fauzan—designed a Chem-E-Car named Ramayana, which is powered by oxygen pressure generated from the decomposition of hydrogen peroxide (H₂O₂) using potassium permanganate (KMnO₄) as a catalyst. The resulting oxygen drives a pneumatic system, creating a clean and emission-free energy source.
Meanwhile, the second team, IO-Kayovoks, claimed the gold medal in the Environmental Science category with their project titled “The Potential of Aluminum-Air Batteries as a Green Energy Source: Design and Implementation in an Electric Vehicle Car Application.” Led by Maya Qisthina Gaissani (Team Leader), the team also included Maeza Dhenta Purniawan, Mochammad Wibisono Faizun Sunarko, M. Dio Pratama, David Auza Sitanggang, and Inas Taqiyyah. They developed an electric vehicle based on aluminum-air batteries, offering not only high energy efficiency and zero emissions but also an automatic stopping system based on the iodine clock reaction and laser sensor technology for high-precision control.
These achievements reflect the dedication and competence of UNDIP Vocational School students in combining chemical engineering principles with sustainable technological innovation. “This achievement is clear proof that vocational students are capable of competing globally. We want to show that applied research from vocational education can contribute real solutions to future environmental and energy challenges,” said Maulana, a member of the Ramayana team.
Their success was also made possible thanks to the guidance of their supervising lecturer, Abdullah Malik Islam Fillardli, S.T., M.T., who played a crucial role throughout the research, experimentation, and scientific writing process for both teams. His mentorship was instrumental in leading the Kayovoks Chem-E-Car teams to international recognition.
High appreciation was also extended to the UNDIP Vocational School and the Teaching Factory Laboratory, which served as the hub for technology development and testing. This victory further solidifies Kayovoks Chem-E-Car UNDIP’s position as a pioneer in eco-friendly vehicle innovation in Indonesia. It serves as an inspiration for other students to continue creating and contributing to the advancement of sustainable green technology.
Mohamad Endy Julianto, Head of the TRKI Program at UNDIP’s Vocational School, expressed his gratitude for this remarkable achievement. “This accomplishment proves that the innovations and inventions of our academic community are being recognized internationally. We hope that research and innovation activities in TRKI will continue to grow and make a real contribution to solving societal problems,” he concluded. (Endy; ed. DHW)
