This initiative was driven by the high number of heart disease cases, largely due to the low public awareness of the importance of early health checkups. In response, the ITB Physics Team took the initiative to develop a simple and affordable heart rate detection device using a non-invasive infrared sensor and a basic microcontroller. The goal is to enable rural communities with limited access to healthcare facilities to use the device independently.
Agus Sara Sawita stated that the program, funded by the 2025 Research, Community Service, and Innovation Grant (PPMI) from the Faculty of Mathematics and Natural Sciences (FMIPA), required approximately six months of preparation. The team first conducted surveys and secured permits at the designated location. They then proceeded to design the device, carry out calibration, and collect data. During the design process, they also studied various health parameters – particularly those related to heart function – in order to provide the community with a general understanding of the topic.

The community service program was held from Friday to Sunday, July 25–27, 2025. During the event, the ITB Physics Team carried out two main activities: data collection using the early heart detection device and a public health awareness campaign promoting a healthy lifestyle. The program was well received by the residents of Raharja Village. The Village Head, Yayat Ruhiyat, expressed his appreciation for the contribution of the ITB Physics Team, highlighting it as a meaningful demonstration of care and synergy between the academic world and the local community.
Although the event went according to plan, the implementation process was not without its challenges.
“We encountered some issues after the device was assembled. Since the device was analog, we had to program it from scratch, which made calculating BPM (beats per minute) a bit challenging. This differs from digital devices that are more practical and ready to use without the need for complex programming,” said Jihan Prihatini, Physics Class of 2022.
Dr. Maria Evita, S.Si., M.Si., the Field Coordinator, expressed hope that the project would make it easier for the community to monitor their heart rate independently using the device.
“This activity left a deep impression on me, personally. I felt that our small contribution was truly appreciated by the community. I hope that community service programs like this can continue – not only in Raharja Village but also in other regions – and that our contributions can extend beyond heart rate detection tools to other forms of meaningful assistance,” she said.
