The Physics Department of Diponegoro University (UNDIP) once again demonstrated its commitment to supporting science education at the secondary level through a community service activity titled “Interactive Simulation-Based Digital Physics Practicum Training to Enhance Interest and Understanding of High School Students in Semarang City.” This event was held on Thursday, February 6, 2025, at SMAN 9 Semarang, involving UNDIP Physics Department lecturers Dr. Suci Faniandari, S.Pd., M.Si., Dr. Drs. Priyono, M.Si., and Dr. Erik Bhekti Yutomo, M.Si. The program represents a concrete effort to address the challenges posed by limited access to physics laboratory equipment in schools.
The training was designed as a solution to the lack of practical physics facilities, a common obstacle in many schools. One of the approaches utilized was the integration of digital technology, particularly the PhET Interactive Simulations platform. These simulations not only enhance students’ understanding of physics concepts but also spark greater interest in science learning through engaging and accessible visual displays.

With PhET, students can conduct virtual experiments, manipulate variables, and observe outcomes in real-time. This allows for a more exploratory and discovery-based learning process, ultimately strengthening the understanding of abstract physics concepts. Such simulations are highly relevant in today’s digital era, where access to technology is increasingly widespread and can be harnessed as an alternative learning medium.
In addition to introducing PhET, the training also equipped teachers with strategies for designing creative experiments using available resources. The team emphasized the importance of inventory management, regular maintenance of equipment, and the use of simple tools to support traditional laboratory activities. Thus, even schools with limited resources can still optimize physics learning.
Interestingly, this activity also involved UNDIP Physics students as part of the implementation team. The students played an active role in providing technical assistance to teachers and students, sharing their academic experiences, and discussing career prospects in the fields of physics and science. Furthermore, they introduced other study programs at Diponegoro University, aiming to broaden students’ horizons and inspire them in planning their educational futures.

The training received positive feedback from both teachers and students at SMAN 9 Semarang. They stated that the digital simulation approach greatly helped them understand topics that were previously difficult to grasp through conventional learning methods. Students showed high enthusiasm, especially when they were able to directly engage with various PhET simulations and discuss their findings.
Through this initiative, the UNDIP Physics Department not only contributed to enhancing the quality of physics education in secondary schools but also fostered broader collaboration between universities and schools. Such community service programs are expected to continue and evolve, in line with the increasingly dynamic and technology-driven needs of today’s educational landscape.
