BANDUNG - Two students of Physical Engineering named Syammary Naufal and Zsi Zsi Meydwika Andwitri, have successfully presented the result of their research in a prestigious global event 'International Conferences on Industrial Technology and Management (ICITM) 2017' which took place at the University of Cambridge, England.
The research conducted by two young physicists of Telkom University is under the direct supervision of a senior Physical Engineering researcher Dr. Abrar Ismardi, and a researcher from the Indonesian Institute of Sciences (LIPI) Gandi Sugandi.
The conference held at Clare College, the University of Cambridge in England on the 7th to 10th of March 2017 was attended by more than 23 countries, including Taiwan, Malaysia, China, Oman, Japan, Saudi Arabia, Thailand, Norway, Mexico, Germany, United Kingdom, Hong Kong, Indonesia, and so forth. From 159 papers that have been submitted, 103 papers get through the selection including the research carried out by young physicists from the Physical Engineering of Telkom University.
Technically, the research entitled 'Simulation and Characterization of Symmetrical Planar Sping FR4-Based Electrodynamic Vibration Energy Harvesting' is an attempt to create devices of producing energy from vibration processes. The device is in the form of micro devices measuring 25 mm x 25 mm. From the results of the research, the devices can produce electric power of approximately 500 to 1000 mV (millivolts), in which the main source of energy comes from vibration (Hertz), or well known as EVEH (Electro Dynamics Energy Harvesting).
Syammary Nauval said the research that has been conducted with his colleague is a part of their final project and a collective work with their supervisors, "We are grateful to get the opportunity to carry out this research, especially on the support of supervisors and Telkom University, and also LIPI. Hopefully, what we have done can be the beginning of the energy independence of Indonesia," he said.
Meanwhile, the Rector of Telkom University, Professor Mochamad Ashari explained that the university would not reluctantly encourage students to collaborate on research in order to realize a better cooperation between Universities and Industry, "We gradually establish this commitment. We have a specific concern related to the technology-based energy development, primarily to support the potential young physicists to always innovate in order that our research will give more impact on the needs of the wider community," he informed reporters in Bandung, Thursday (03/23/2017).
According to him, the working principle of the micro devices uses the Faraday's law and Resonance Frequency. A device consists of a thin membrane of PCB-FR4 material (made through a laser cutting method) and magnet which is attached to the membrane, and then surrounded by coils.
Therefore, when there is vibration toward the membrane (which is affected by the environment due to resonance process), there will occur electromotive force due to the effect of reaction between the magnet and the coils, so that at the edges of the coil there will be generated energy voltage.
During the meeting at the University of Cambridge in England, hundreds of researchers from around the world competed with each other to present the results of their research in front of all participants who were students in all strata, Professor of Technology, Researchers and Industries.
"The publication of the research will also be recorded in the indexed world Journals by the IEEE which is indexed as Scopus, Ei Compendex, in which the indices among the world's academic researchers is prestigious," he said. (MAT)
