Semarang, 22 December 2025 — The Faculty of Medicine, Diponegoro University (Universitas Diponegoro/UNDIP) has conferred a new doctoral degree upon Dr. Sera Budi Verinda, S.Si., M.Biomed., who successfully completed the Doctoral Program in Medical and Health Sciences after defending her dissertation.
Her dissertation, titled “Pengaruh Mikro-Nano Gelembung Plasma Ozon (MNG PLAZON) terhadap Polutan pada Hospital Wastewater (HWW): Kajian terhadap Efektivitas Mikro-Nano Gelembung Plasma Ozon dalam Meningkatkan Kualitas HWW berdasarkan Aspek Makro- dan Mikropolutan.”, investigates the use of micro–nano plasma-ozone bubbles as an advanced oxidation process for hospital wastewater treatment.
Supervised by Prof. Dr. Muhammad Nur, Prof. Gunawan, PhD, and Dr. Helmia Farida, M.Kes., Ph.D., Sp.A(K), the study examines both macro-pollutants and micro-pollutants, highlighting the potential of this technology to improve hospital wastewater quality while offering a solution positioned as effective, environmentally friendly, and applicable to medical-waste management systems.
The doctoral promotion examination was held at the Faculty of Medicine, UNDIP, and was attended by faculty leadership, the supervisory team, examiners, and members of the academic community. The session reflected strong academic appreciation for scientific contributions considered relevant to environmental health challenges and the sustainability of healthcare services.
Following this achievement, Dr. Verinda is expected to further strengthen interdisciplinary research spanning biomedicine, environmental health, and plasma-ozone technology, and to encourage the downstream application of research outputs supporting safer and more sustainable hospital-wastewater management in Indonesia.
Dr. Verinda completed her doctoral track with support from the PMDSU (Program Magister sampai Doktor Sarjana Unggul) scholarship at Diponegoro University for four years. Her academic journey includes an undergraduate degree in Physics, a master’s degree in Biomedical Science, and doctoral work in Medical and Health Sciences with a focus on antibiotic degradation. After completing her master’s program at UNDIP, she was appointed as a civil-servant lecturer at the Faculty of Medicine, IPB University. Post-doctorate, she plans to expand the application of medical ozone for therapy in collaboration with medical colleagues at IPB University.
