This news publication also aims to provide official information and documentation to the academic community and the public regarding the outstanding academic achievements of students from the Department of Physics at UGM.

From April 21 to 24, 2025, doctoral students from the Department of Physics at Universitas Gadjah Mada, namely Kurnia and Sudarmono, actively participated in the International Conference of Asian Union of Magnetics Societies (IcAUMS) 2025, held at the Okinawa Convention Center in Okinawa, Japan. This prestigious conference serves as a major platform for researchers, scientists, and engineers from across Asia and beyond to share the latest advancements and breakthroughs in the field of magnetism and magnetic materials.

The IcAUMS 2025 conference featured a wide range of topics including spintronics, magnetic nanomaterials, magnetic sensors, and biomedical applications of magnetics. It provided an excellent opportunity for participants to present their research findings, engage in scientific discussions, and establish valuable collaborations with international experts.

In addition to the doctoral students, the conference was also attended by master’s students Siti Fatimah Azzahro and Husna Ajrina, who are part of the same research group known as ES-Club. Their joint participation highlights the strong collaborative spirit within the group, fostering knowledge exchange and mentorship between different academic levels.

The delegation from UGM was accompanied and guided by Prof. Dr. Eng. Edi Suharyadi, whose expertise and support were instrumental in maximizing the benefits of this international exposure for the students.

Overall, the participation of UGM students in IcAUMS 2025 not only enhanced their academic and research capabilities but also strengthened the university’s presence in the global scientific community. This experience is expected to inspire further innovation and collaboration in the field of magnetics research.

During the conference, the students were accompanied by Prof. Dr. Eng. Edi Suharyadi, S.Si., M.Eng., who provided academic guidance and support. The presence of their supervisor was crucial to ensure the smooth participation of the students and to help them maximize the benefits of this international conference.

IcAUMS 2025 is organized by the Asian Union of Magnetics Societies (AUMS) and serves as a premier platform for scientific discussions related to magnetism, magnetic materials, and their applications. The conference gathers researchers, engineers, and experts from across Asia and beyond to share the latest advancements, foster collaborations, and promote innovation in the field.

The participation of UGM students in this event not only enhances their academic experience but also strengthens the university’s presence in the global scientific community.

The Department of Physics at Universitas Gadjah Mada (UGM) has achieved international recognition again. Nugraheni Puspita Rini, a doctoral student in Physics at UGM, won the “Best Oral Presentation” award at the prestigious International Symposium on Advanced Magnetic Materials and Applications (ISAMMA) 2024. The event, held in Vietnam from August 4-8, 2024, attracted 300 participants from 20 countries.

ISAMMA, a biennial symposium, provides a platform for scientists and researchers to present the latest innovations and research in magnetic materials. This year, Nugraheni impressed the judges with her presentation titled “Photocatalytic Degradation of Rhodamin B using Green Synthesized Fe3O4/rGO/ZnO Magnetic Nanocomposite Utilizing Moringa Oleifera and Amaranthus Viridis Leaf Extract.” Her research explores the use of eco-friendly magnetic nanocomposites to degrade Rhodamin B dye, utilizing Moringa and Red Amaranth leaf extracts as key components in the synthesis.

Nugraheni’s success in this research not only makes a significant contribution to the field of magnetic materials but also aligns strongly with the Sustainable Development Goals (SDGs). Her research supports several SDGs, including SDG 6 (Clean Water and Sanitation), SDG 9 (Industry, Innovation, and Infrastructure), and SDG 12 (Responsible Consumption and Production). By developing effective technology for degrading pollutants like Rhodamin B, her research contributes to maintaining clean water and adequate sanitation. The innovation in using natural materials for synthesizing magnetic nanocomposites reflects advancements in environmentally friendly technology that can support sustainable industrial development. Using natural materials such as Moringa and Red Amaranth leaves also demonstrates a commitment to sustainable and responsible production practices.

Nugraheni’s achievement brings pride not only to herself but also to the UGM Physics Department and the entire academic community. This success demonstrates the quality of research and innovation produced by UGM students, showing they can compete internationally and support global sustainability goals. It is hoped that this achievement will inspire all students and researchers to continue creating and achieving for a better and sustainable future.
