On Wednesday, July 9, 2025, to Thursday, July 10, 2025, the Physics Study Program once again held its biennial event, INDY 2025. This year’s INDY carried the theme Fourier, Heisenberg, and the Rise of Wavelets: “A New Lens on Physics”. The speakers for INDY 2025 included Drs. Janto V. Sulungbudi, Paulus C. Tjiang, Ph.D., and Reinard Primulando, Ph.D. The event was attended by high school students from Jakarta and Bandung, as well as UNPAR Physics students.
On the first day, the event began with an opening speech by Risti Suryantari, Ph.D. as the chair, followed by a welcome address from Haryanto, Ph.D., Dean of the Faculty of Science. The first session was delivered by Paulus C. Tjiang and Reinard Primulando, covering topics on the principles of Fourier analysis and the Heisenberg Uncertainty Principle (Heisenberg–Gabor limit). This was followed by Janto V. Sulungbudi discussing applications of wavelets.
The next session was a parallel session, where participants were free to choose the session they wished to explore further. These sessions were divided into theoretical and applied tracks. The Science Workshop (Bengkel Sains) also enlivened the event with science demonstrations for the participants, serving as the closing activity of the first day.
The second day began with the continuation of the parallel sessions, where participants who had chosen their sessions on the first day continued their discussions with the speakers.
The event concluded with a group photo session and the presentation of certificates to the speakers. INDY 2025 was not only a platform for sharing knowledge between academics and participants but also an inspiring forum that brought together fundamental concepts in physics with modern approaches such as wavelets. The presence of expert speakers and the enthusiasm of participants from diverse backgrounds reaffirm that physics remains a dynamic and relevant science. May the spirit of collaboration and intellectual curiosity fostered at INDY 2025 continue to thrive and serve as a valuable foundation for addressing current and future challenges in physics.
