Rajab Bullah Anggara Nasution, Akbar Muntaqo, Nugraheni Novita Hutami, and Fathia Aqila Zatadini are students in the Industrial Engineering Program, Faculty of Industrial Technology (FTI), Universitas Islam Indonesia (UII). They successfully won a Bronze Medal at INDES 2025. The International Invention, Innovation and Design Competition (INDES) 2025 is a competition for innovation and design that brings together various creative ideas in the form of innovative products or works. The event took place on June 26, 2025, and focused on aspects of innovation, invention, and product design.
In this competition, the team developed the ECOBARA STOVE, an eco-friendly incinerator innovation designed to support more efficient waste management. This project serves as a waste management solution by designing a more environmentally friendly and beneficial waste incinerator. This achievement demonstrates that UII Industrial Engineering students are capable of providing solutions to environmental problems through innovation.
From Team Discussions to Final Presentations
The competition began with the development of ideas and product concepts together with all team members. Preparations included researching incinerators and waste management. In addition, the team developed the ECOBARA STOVE concept and created presentation materials and supporting media. During this phase, tasks were assigned based on each team member’s capabilities and skills.
The biggest challenges the team went through were managing their time and aligning ideas among members. They also had to explain the incinerator concept in a way that was easy for the judges to understand. The team overcame these challenges through effective communication, clear task allocation, and joint evaluations before the event day. With perseverance and teamwork, the project was successfully presented. The project was evaluated based on innovation, creativity, benefits, and thematic relevance, ultimately leading the team to win a Bronze Medal.
A Valuable Experience Behind the Bronze Medal

For Rajab, one of the team members, INDES 2025 was a valuable experience in developing innovative ideas, building teamwork, and building confidence when presenting the project. The process they went through together underscored the importance of listening to each other’s opinions and resolving challenges collectively. The team’s unity was the key to their success in winning the Bronze Medal.
“Don’t be afraid to try entering competitions. From competitions like this, we can gain experience, broaden our horizons, practice teamwork, and boost our self-confidence. The key is to dare to start, be willing to learn, and stay motivated throughout the process,” said Rajab.
Rajab also emphasized that a simple idea can become a useful project if developed with dedication. The team’s courage proves that innovations born from a concern for the environment can compete on the international stage.
