Semarang, June 13, 2025 – The Department of Physics at Universitas Diponegoro once again hosted its Praktisi Mengajar (Practitioner Teaching) program, aiming to strengthen the connection between academic theory and industrial practice. This session, titled “Effects of Pumping Medium Temperature to the Pump Performance,” featured a special guest speaker, Antonius Giri Martanto, S.Si., M.Si., a seasoned professional from PT KSB Indonesia specializing in industrial pump engineering.
Held online via Zoom, the lecture was attended by 128 students enrolled in the Thermodynamics course, along with several faculty members. The event began with opening remarks from a representative of the Physics Department, followed by the main presentation by the guest speaker.
In his presentation, Mr. Antonius systematically explained how temperature changes in the pumped fluid affect its physical properties—such as viscosity, density, and vapor pressure—and how these changes impact pump performance, efficiency, power consumption, and the risk of cavitation. His explanation was enriched with real-world industrial case studies, providing students with a concrete and applicable understanding of the topic.
The discussion session was highly interactive. Students posed thoughtful questions about the implementation of thermodynamic principles in fluid systems and the engineering solutions used in practice. The high level of engagement reflected the success of the session in sparking interest and deepening students’ comprehension.
This event is a result of collaboration between the Department of Physics, FSM UNDIP, and the industry sector, demonstrating the faculty’s strong commitment to enhancing education through practical, real-world applications aligned with current workforce needs.
Through this program, students not only gained theoretical knowledge but also valuable insight from an experienced industry practitioner. It is hoped that initiatives like this will continue to grow, fostering the development of physics graduates who are competent, adaptive, and ready to compete in the industrial world.
