Wed (9/21), the study program of Automation Engineering Technology Vocational College Undip held the third series of Visiting Lecturer webinar, with Dr. Yono Hadi Pramono, M.T., a lecturer from Departement of Physics ITS, as the presenter.
This webinar was held through Zoom conference and attended by 70 – 80 participants from numerous institutions, e.g. the students from Undip’s Automation Engineering Technology, ITS, IAIN Salatiga, Universitas Jember, etc. The webinar started at 2 pm and closed at 4 pm local time, with a stimulating discussion.
The topics presented by Dr. Yono was “The Utilization of Optoelectronics and Electromagnetic Technology as Sensors”. At the beginning of the presentation, Dr. Yono stated that the automation engineering program has a huge opportunity in the future, because the ability to create a device that can represents or helps people’s job. Of course, the represented job must be appropriate, efficient, and beneficial for human life.
The main topic of the webinar was divided into two themes, namely the use of optoelectronics and the use of electromagnetic in life. The use of optoelectronics are very broad, e.g. telecommunication laser, blue laser, fiber optic, solar panels, etc. Because of the characteristics and superiority of optoelectronic devices, it can be applied as sensors on many field such as health, chemistry, magnetic, rotation sensor, industry, automotive, etc. The characteristics that can be utilized as sensors are intensity, frequency variation, phase modulation, and polarization. These characteristics can be used to sense something without changing the shape of the object (non destructive).
On the second theme, Dr. Yono stated that the utilization of electromagnetic can be seen on capacitive sensor, inductive sensor, LVDT and RDVT sensor. Furthermore, Dr. Yono showed his interesting research on the application of Microwave (high frequency) sensors. He made an early warning system for tectonic earthquakes, utilizing the results of reflection, absorption, and scattering on the ionosphere layer when induced by electromagnetic waves.
The discussion session was held after the presentation sessions ended. The participant was very enthusiast to ask questions to Dr. Yono, until the end of discussion session there were still many participants who wanted to ask questions.
The third series of Visiting Lecturer webinar provide a very broad view for the participants, especially for Automation Engineering Technology’s students, so there are lots of opportunities for the development in the field of automation itself. The webinar was closed by a statement from Dr. Yono, he stated that whoever masters the height, they will rule the world.
