SEEI ITB Students Achieve Outstanding Results at the National Electrical Summit UI 2025

Bandung, stei.itb.ac.id – Students of the School of Electrical Engineering and Informatics (SEEI) ITB once again achieved remarkable success at the National Electrical Summit (NEST) UI 2025, a national scientific competition organized by the Electrical Engineering Student Association of the Faculty of Engineering, Universitas Indonesia (IME FT UI). The competition centers on innovation in Electrical Engineering and supports efforts toward renewable energy transition through a series of technical and scientific challenges. Activities began in late September and culminated on 2 December 2025 in the final round held at Universitas Indonesia.

In this event, two SEEI ITB teams—“Aroes Koeat” and “Ohm My God”—participated in the Study Case Competition, while another SEEI ITB team competed in the Idea Competition category. The study case challenge assigned to the “Aroes Koeat” and “Ohm My God” teams focused on reducing a small island in Sumba’s dependence on a PLTD-based power system by designing renewable energy solutions using a combination of PV (solar), wind power, and batteries, aiming for 80–100% renewable energy penetration while maintaining affordable electricity costs.. . . .. . .  .

The “Aroes Koeat” team presented a project titled “Design of a Hybrid Energy System Based on Solar PV, Wind Power, Diesel Generators, and BESS to Enhance Reliability and Renewable Energy Penetration on Remote Islands in Sumba.” In their work, they applied concepts learned in coursework, supported by generator capacity optimization using Excel’s Solver feature. Their approach also referred to national energy programs and regulations, including the dieselization reduction initiative, the Net Zero Emission target, and energy policies such as Ministerial Regulations (Permen ESDM) and the RUPTL roadmap. The team included economic analysis and projected energy demand through 2045 to ensure that the proposed solution was both realistic and forward-looking. Ahead of the final round, the team prepared a presentation deck, practiced an 8-minute pitching session, and anticipated judges' questions to strengthen their delivery. The “Aroes Koeat” team consisted of Roni Septian, Adnein Hasna Al-Achyar, and Raffa Andhika Ilham. . .

Meanwhile, the “Ohm My God” team also developed a renewable energy solution using solar PV, wind, and battery storage to address the same study case. The team leader handled the core technical aspects, while Abie focused on research into technological innovations, and David analyzed socioeconomic impacts and economic feasibility. Clear task distribution and well-structured work targets served as their main strategy in completing the challenge. Despite difficulties in aligning schedules due to individual commitments, the team managed to maintain consistent progress by regularly updating their work and optimizing discussion time. The competition provided an opportunity for the team to apply knowledge from the 2024 Power Engineering curriculum while aligning technical innovations with real-world conditions. The “Ohm My God” team consisted of Natanael C. Pangaribuan, Abizar Diaz Ulhaq, and Raffa Dominikus David.

The SEEI ITB team that secured 3rd Place in the Idea Competition proposed an innovative concept involving microalgae cultivation using Metal–Organic Framework (MOF) technology installed along highway shoulders to generate electricity for the grid, supported by a Battery Energy Storage System (BESS). The idea originated from discussions during their internship and evolved into a cross-disciplinary collaboration, recognizing that integrating knowledge from different fields was their key strength. The team consisted of Marcelinus Aryo Wicaksono, who worked on biogas-to-electricity conversion and electrical system configuration and simulation using DIgSILENT; Hanif Yusran Makarim (SITH ITB), who handled microalgae processing into biogas through thermal pretreatment; and Ravi Adriansyah (FTMD ITB), who focused on MOF technology for microalgae cultivation and performed CO₂ absorption simulations. ..

The achievements of SEEI ITB students at the National Electrical Summit UI 2025 demonstrate their academic excellence and strong problem-solving capabilities in addressing future energy challenges. Their success is expected to inspire other students to continue innovating and contributing to the development of renewable energy technologies in Indonesia.
