UNDIP, Semarang (9/10) – Universitas Diponegoro (UNDIP) has once again demonstrated its contribution to advancing science through its lecturers’ scientific publications and citations. Several UNDIP academics were listed in the “Updated Science-Wide Author Databases of Standardized Citation Indicators, published by the Elsevier Data Repository” on October 7, 2026.
This achievement also reflects the increasingly significant contribution of UNDIP academics to the global scientific community. The inclusion of UNDIP researchers in an international database not only reflects their publication productivity but also demonstrates that their scientific work has become a reference for advancing knowledge across various fields. This citation-based recognition is one indicator of the university’s academic reputation, built through research quality, consistency in publication, and international research collaboration networks.
In the ‘Career-Long Impact or All Years’ category, three UNDIP lecturers were listed: Prof. Dr. Ir. Hadiyanto, S.T., M.Sc., IPU; Prof. Dr.rer.nat. Ir. Heru Susanto, S.T., M.M., M.T.; and Prof. Sugiharto, S.Pt., M.Sc., Ph.D. This category reflects the citation impact of a researcher’s academic work through the end of 2025.
The database, developed by John P. A. Ioannidis, contains scientific citation indicators for researchers from various disciplines based on Scopus data. The ranking includes two main categories: ‘Career-Long Impact’, which measures citation impact throughout a researcher’s career, and ‘Single-Year Impact’, which measures citation impact during 2025.
Meanwhile, the ‘Single-Year Impact’ category highlights the influence of scientific publications based on citations received during the 2025 calendar year. This category provides an overview of researchers’ contributions and the visibility of their scientific work in recent developments in knowledge.
UNDIP Rector Prof. Dr. Suharnomo, S.E., M.Si., expressed his appreciation to the lecturers who received recognition in the database of influential scientists worldwide. According to him, the achievement reflects UNDIP’s commitment to building academic excellence through high-quality research that remains relevant to global scientific developments.
“The inclusion of seven UNDIP lecturers among the world’s influential scientists is both a source of pride and a reminder that the quality of a university is built through consistent academic work. This is the spirit of ‘UNDIP Noble’—delivering academic excellence that is internationally recognized. However, this excellence must go hand in hand with the spirit of ‘UNDIP Valuable’, where knowledge and research findings can provide real solutions to society’s challenges,” he said.
The Rector added that international recognition of UNDIP researchers should serve as inspiration for the entire academic community, particularly lecturers and young researchers, to continue developing research that is not solely publication-oriented but also contributes to national development.
“For UNDIP, international reputation is not the final goal. Reputation must become a pathway to expand the benefits of knowledge. We want more UNDIP research to become global references while also being applied to address the nation’s challenges, ranging from food security, energy, the environment, and health to technological development,” he emphasized.
