UNAIR NEWS – Universitas Airlangga (UNAIR) students made another achievement through the International Invention Competition for Young Moslem Scientist 2021 (IICYMS 2021), a competition held by the Indonesian Young Scientist Association.
In the competition, a team of five students won a gold medal and Macedonia Special Awards for their innovation on lie detector technology. IICYMS 2021 was an international competition participated by 17 countries, including Malaysia, Singapore, and Turkey.
Gina Yunita Pranosa as the team leader said that lie detectors generally use special sensors and polygraphs to measure heart rate. Meanwhile, the lie detector being developed by Gina and her team uses fiber optics to measure heart rate and detect lies.
“By using fiber optics, we can get a much more accurate lie detection. In the heart rate range of 50-300 bpm, we have proven that the linearity level is almost 100 percent,” said the 2019 Physics study program student.
Furthermore, the lie detector developed by her team has a simpler design. Moreover, the high accuracy level can be achieved with low fabrication costs. Thus, according to Gina, this innovation can be easily applied in the field.
Gina said that the innovation was greatly inspired by a research journal entitled Fiber Optic Sensor Heart Rate Detection. The innovation is a real application of the scientific hypothesis proposed in the journal.
Participating in the innovation-based science competition was not easy amid of the Covid-19 pandemic. With approximately two months of preparation, the team had to go through various revisions for the presentation video.
“Moreover, we were also unable to present in full team because two of our members had to take a rest due to health,” said Gina.
Meanwhile, Prof. Dr. Retna Apsari as the supervisor gave positive comments to the team. The Physics Professor explained that the development of fiber-optic-based heart rate detection was first developed by her at the Photonics Laboratory, Faculty of Science and Technology UNAIR, with other physicists from UNAIR, Prof. Dr. Moh. Yasin and Yhosep Ghita Yhun Y., S.Si., MT.
Prof. Retna also said that this year’s achievement is hope and trigger for Physics and UNAIR students to continue to excel in the national and international arenas.
“Of course, we hope that this innovation can be applied optimally in the forensic world. Moreover, in collaboration with the Department of Physics UGM, this optical-sensor-based research innovation can also be used for the detection of volcanic movement and it has received research funding from RKI for two years. We open opportunities for collaboration with all UNAIR academics and practitioners outside UNAIR to maximize the results of research based on fiber optic sensors and their supporting aspects,” she said.
