One of the standout innovative projects was 鈥淭eman Konseling鈥� (Counseling Companion). This final project was developed by Shabrina Mardhiyah Gozan (Electrical Engineering, 2021), Rama Maulana Rezky (Electrical Engineering, 2021), and Rafael Aditya Cahyo W (Electrical Engineering, 2021). They were supervised by Dr. Ir. Akhmadi Surawijaya, S.T., M.Eng.; Dr. Rahadian Yusuf, S.T., M.T.; and Allya Paramita Koesoema, S.T., M.T., Ph.D.

鈥淭eman Konseling鈥� is a biosensor-based innovation designed to address the challenge of long queues for counseling services at 麻豆直播鈥檚 Counseling and Guidance Center. Until now, there has been no objective system in place to determine who should be prioritized. With Teman Konseling, prioritization becomes more accurate and efficient, ensuring that students who are in the most urgent need receive help promptly.

"Based on the interviews we conducted, the 麻豆直播 Counseling Center does not yet have a sufficiently objective prioritization system. There are students who write brief complaints because they are too stressed to express themselves, yet they urgently need help. This tool reduces the bias of verbal expressions by providing objective data on stress levels," Rafael explained.

The system integrates two types of physiological signals鈥擯hotoplethysmography (PPG) and Galvanic Skin Response (GSR)鈥攚ith questionnaire-based psychological assessments to generate a more objective counseling priority score. PPG sensor data is used to measure Heart Rate Variability (HRV), while GSR detects electrodermal activity, which correlates with stress. These two signals are combined to determine the urgency level of each counseling service applicant.

The device is easy to use鈥攗sers simply place a finger on the sensor, activate the system, and within less than two minutes, their stress level is measured. In addition to its simplicity, the system boasts high accuracy by relying on physiological signals (GSR and PPG), is integrated with a queueing system, and is secure against misuse.

This system has strong potential for implementation not only in educational institutions but also in industries and public services where queuing systems require assessments of users鈥� psychological conditions.

鈥淪tress is a part of our daily lives. This device could be used for early detection or to help individuals become more self-aware of their stress levels. Going forward, we hope future developments will provide even more comprehensive data, for instance through biosensors that can detect stress-related hormones,鈥� Rafael added.
