Semarang, April 20, 2025 – Students from the Applied Bachelor’s Program in Industrial Chemical Engineering Technology (TRKI), Vocational School of Diponegoro University (UNDIP), have once again made Indonesia proud on the international stage. At the prestigious Jakarta International Science Fair (JISF) 2025 Online Competition, held from April 15 to 17, two research teams from UNDIP’s Kayovoks Chem-E-Car community secured two gold medals in different categories: Engineering and Environmental Science.
Team Ramayana: Emission-Free Car Powered by Chemistry
The first team, known as Kayovoks Ramayana, took home the gold in the Engineering category with their project titled “Advancing Green Automotive Prototypes: Chemical Reaction-Driven Oxygen Generation and Pneumatic Propulsion”. They developed a Chem-E-Car prototype powered by oxygen gas generated through the decomposition of hydrogen peroxide (H₂O₂) using potassium permanganate (KMnO₄) as a catalyst. This oxygen is then used to drive a pneumatic propulsion system, creating a zero-emission, environmentally friendly vehicle.

The team members—Akhmad Surya Adi Maulana, Muhammad Zidan Fadilah, Devano Gothicardo, Rizki Ananda, Ilyas Nur Hidayat, and Hamaz Al-Fauzan—demonstrated how basic chemical principles can be applied to real-world, green transportation solutions.
IO-Kayovoks: High-Tech Electric Car Using Aluminum-Air Battery
Meanwhile, the second team, IO-Kayovoks Team, clinched the gold 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”. This team created an electric vehicle powered by Aluminum-Air Batteries, known for their high energy density and zero emissions.

The innovation doesn’t stop there—the vehicle is also equipped with a high-precision laser sensor and an iodine clock reaction-based system for automatic stopping, making it not only eco-friendly but also smart and safe. The team members include Maya Qisthina Gaissani (Leader), Maeza Dhenta Purniawan, Mochammad Wibisono Faizun Sunarko, M. Dio Pratama, David Auza Sitanggang, and Inas Taqiyyah.
Proving That Vocational Students Can Compete Globally
These achievements showcase the ability of UNDIP’s vocational students to excel on the global stage through hands-on research and sustainable technology innovation. “Through this project, we aim to prove that vocational students can also become leaders in solving global energy and environmental challenges,” said Maulana, a representative of Team Ramayana.
The success of both teams was made possible by the dedicated mentorship of Abdullah Malik Islam Fillardli, S.T., M.T., who guided the students through the entire process—from conducting experiments to crafting their scientific papers.
Strong Campus Support and a Vision for the Future
Appreciation also goes to the Vocational School of UNDIP and its Teaching Factory Laboratory, which have served as nurturing grounds for innovation and technological development. This victory further solidifies Kayovoks Chem-E-Car UNDIP’s role as a trailblazer in Indonesia’s green automotive movement.
Mohamad Endy Julianto, Head of the TRKI Program, expressed his pride and optimism: “This achievement is solid proof that innovations from our vocational academic community are internationally recognized. We hope to see more research and inventions like this, bringing real solutions to society’s challenges.”
With this outstanding achievement, UNDIP’s vocational students are not only making headlines—they are also shaping the future of sustainable energy in Indonesia, one breakthrough at a time.
