Awesome! Udayana University's BioSmart Physics Team Makes History at PIMNAS 2025

Denpasar, November 1, 2025 — History has finally been made. For the first time since the Udayana University Physics Study Program was founded in 1984, physics students have successfully qualified for Indonesia's most prestigious scientific event, the 28th National Student Scientific Week (PIMNAS). Held at Hasanuddin University (Unhas), 420 teams from 170 universities across Indonesia participated. The prestigious event took place from November 23–28, 2025.

This impressive achievement was achieved by the BioSmart Team, led by Ni Luh Putu Ardini Astina Putri, along with I Nyoman Aditya Pramana and Haidar Mursyid Sumarna, students of the Physics Study Program, Faculty of Mathematics and Natural Sciences (FMIPA), Udayana University. They were declared to have qualified for PIMNAS 2025 through the Student Creativity Program (PKM) in the Exact Research (PKM-RE) scheme.

The BioSmart team conducted research entitled "Green Synthesis of CoFe?O?/Ag Nanoparticles for Creatinine and Glucose Detection Using a Surface Plasmon Resonance-Based Biosensor" under the guidance of I Putu Tedy Indrayana, S.Pd., M.Sc. This work was deemed worthy of being presented at PIMNAS by the national review team of PKM from the Directorate of Learning and Student Affairs (Ditbelmawa), Ministry of Higher Education, Science, and Technology of the Republic of Indonesia. PIMNAS XXXVIII will be held on November 23–28, 2025, at Hasanuddin University, Makassar.

This achievement is not merely qualification for the competition, but a historic milestone for the Physics Study Program at Udayana University. After more than four decades, physics students have finally reached the national stage and demonstrated that physics is not only theoretically sound, but also relevant and provides solutions to real-world problems in society.

The BioSmart Team's research focuses on strengthening science and technology in the healthcare sector, specifically developing a detection system for important biomolecules such as glucose and creatinine in bodily fluids, such as urine. These two biomarkers play a crucial role in diagnosing Chronic Kidney Disease (CKD), the prevalence of which continues to rise both nationally and globally.

According to data from the Indonesian Ministry of Health in 2018, the prevalence of CKD reached 0.38%, or approximately 3.8 per 1,000 people, and continues to show an increasing trend. Globally, the prevalence of CKD has even reached 13.4%, as reported by Zhang and Cheng-Lv in the journal Advances in Experimental Medicine and Biology (2019). Progressive decline in kidney function leads to impaired excretion of essential substances, including creatinine and glucose, making early detection key to preventing further complications.

Addressing this challenge, the BioSmart Team designed an optical biosensor based on Surface Plasmon Resonance (SPR) combined with CoFe?O?/Ag nanoparticles. This material innovation is expected to increase the sensitivity and accuracy of biomarker detection quickly and precisely.

Equally interesting, the nanoparticles were synthesized using green synthesis, an environmentally friendly approach that is more sustainable than conventional chemical methods. The research, proposed to begin in June 2025, includes characterizing the physicochemical properties of the nanoparticles and testing the performance of the biosensor in detecting variations in creatinine and glucose concentrations.

During the four months of research, the BioSmart Team not only honed their academic and experimental skills but also demonstrated that physics students are capable of producing applied innovations with real impact. This success serves as a source of inspiration and motivation for all Udayana University Physics students to continue daring to dream, innovate, and play a role in addressing global health challenges.

From a small laboratory to the national stage, the BioSmart Team has proven that new history can be carved through courage, hard work, and an unwavering scientific spirit.
