UNDIP, Semarang (July 2, 2025) – Universitas Diponegoro (UNDIP) held a scientific presentation by three prospective professors on Wednesday, July 2, 2025, at the Academic Senate Meeting Room, 3rd floor of the SA-MWA Building, Tembalang Campus.
The three candidates included Dr. Eng. Achmad Widodo, S.T., M.T. from the Faculty of Engineering; Dr. Ngadiwiyana, S.Si., M.Si. from the Faculty of Science and Mathematics; and Dr. Ir. Limbang Kustiawan Nuswantara, S.Pt., M.P., IPU. from the Faculty of Animal and Agricultural Sciences.
Dr. Eng. Achmad Widodo, S.T., M.T. presented a study titled “Machine Learning-Based Diagnosis and Prognosis for Future Engineering System Maintenance.” His research focused on developing machine learning (ML) and artificial intelligence-based technologies to support future maintenance strategies for engineering systems.
The ML models developed were capable of accurately detecting early performance degradation, diagnosing failures, and predicting the timelines of these failures. These AI-driven diagnosis and prognosis technologies hold significant potential for application in future prescriptive and cognitive maintenance systems, offering more innovative, more adaptive, and efficient solutions to sustain the manufacturing and energy industries.
Such systems have demonstrated increased equipment reliability and operational efficiency. The proposed technology enables anomaly detection, root cause analysis, and prediction of the remaining useful life (RUL) of equipment. This innovation marks a shift from reactive to predictive and prescriptive maintenance strategies, positioning it as a cutting-edge solution for sustainable industry.
In the second session, Dr. Ngadiwiyana, S.Si., M.Si. presented a study titled “Development of Eugenol-Based Organic Polymers to Support a Better Life.” His work addressed environmental challenges arising from the use of fossil fuels and petrochemical-based synthetic polymers, approached through the lens of green chemistry.
Eugenol-based polymers offer environmentally friendly, functional materials for applications in energy and coating technologies. Structural modifications and crosslinker support yield robust, stable polymer networks with superior electrochemical and protective properties, making them highly promising for future energy storage and conversion technologies.
Next, Dr. Ir. Limbang Kustiawan Nuswantara, S.Pt., M.P., IPU, delivered a presentation titled “Strategies to Enhance Milk Production through Ruminal Manipulation.” His study examined the use of leguminous trees, such as Calliandra, Indigofera, and Gliricidia, in livestock feed to enhance dairy cow productivity.
Feeds rich in protein that is digestible in the small intestine, combined with regulated supplementation of rumen-bypass protein and essential amino acids, can enhance milk production efficiency and reproductive health in livestock. Dr. Limbang emphasized the importance of feed quality, noting that legumes—with their high protein content, crude fiber, and essential micronutrients—support optimal rumen function, leading to increased milk yields.
These scientific presentations reflect UNDIP’s substantial contribution to innovation with real-world impact across sectors. The research aligns with UNDIP’s vision of becoming a World Class University (WCU) through transformative, interdisciplinary studies. This effort reaffirms the university’s commitment to developing science that is both relevant and solution-oriented for the benefit of Noble and Valuable UNDIP. (Public Communication/UNDIP/Zaila)
