BANDUNG, itb.ac.id – A student team from the Institut Teknologi Bandung (ITB), known as Team FLUX, successfully won 2nd Place in the Gandeng x TBS Renewable Energy Ideation Challenge 2025. The team advanced through a rigorous selection process involving more than 100 national teams, a series of mentoring sessions, and ultimately the final pitching stage.
Team FLUX consists of Ghifari Jauhar Yajri (Petroleum Engineering), Syakira Fildza Nazhifan (Information Systems and Technology), and Inggried Amelia Deswanty (Information Systems and Technology).
BioSync: A Circular Energy Innovation from Livestock Waste
Aligning with the theme “Powering the Transition to a Net Zero Future”, Team FLUX presented a proposal titled “BioSync – Smart Circular Energy System,” a solar-powered biodigester integrated with Internet of Things (IoT) technology.
This innovation aims to address two major issues: the low utilization of organic waste in the livestock sector—one of the contributors to high methane emissions—and the limited access to clean and affordable energy in rural areas.

“We offer a solution that transforms livestock waste into biogas as a clean energy source, while also producing organic fertilizer for local agriculture,” said team representative Ghifari.
“With BioSync, we aim to turn environmental challenges into opportunities for energy,” he added.
Creative, Feasible, and Scalable Innovation
Team FLUX’s work was recognized for meeting three core criteria of the competition: creative, feasible, and scalable.
-Creative: BioSync integrates a biodigester, solar panels, and an IoT monitoring system into a single circular energy ecosystem.
-Feasible: The financial analysis shows an estimated Return on Investment (ROI) of 11.67% with a projected payback period of 6.4 years.
-Scalable: The business model is designed to grow in stages, starting with a B2C pilot project in Lampung and expanding toward B2B2B and B2G schemes for national-scale implementation.
Competition Challenges and the Final Stage
In the final round, Team FLUX presented their idea before professional judges, including Dimas Adi Wibowo, President Director of New Energy at PT TBS Energi Utama Tbk, and Anugraha Dezmercoledi, Executive Director of TBS Foundation.

The team shared that their biggest challenge was combining technical, digital, and business approaches into one realistic solution, while also managing academic responsibilities, thesis preparation, and organizational activities.
When announced as the 2nd Place winner, the team expressed their pride and gratitude.
“After weeks of discussion, revisions, and presentation simulations, our hard work finally paid off,” they said. “We are proud to contribute a concrete idea for Indonesia’s energy future.”
Looking ahead, Team FLUX plans to further develop BioSync into a real-world project and is exploring collaboration opportunities for a small-scale pilot implementation.
They also offered a message for fellow students. "Don’t wait for your idea to be ‘perfect’ before taking action. Competitions are not just about winning—they’re about sharpening your mindset. From that first step of courage, new opportunities will begin to open.”
