Saturday, October 9, 2021, the Department of Chemistry Education, Faculty of Mathematics and Natural Sciences, UNY, held a Webinar Series #5 by inviting expert speakers in the field of chemistry. The webinar, which was held online via Zoom Meeting, was attended by 198 participants including teachers, students, lecturers, and practitioners in the chemistry field. Prof. Dr. Jaslin Ikhsan, PhD as the Deputy Dean for Academics and Cooperation at the Faculty of Mathematics and Natural Sciences, UNY, gave his remarks as part of the opening of this Webinar Series #5. On this occasion, the Department of Chemistry Education, Faculty of Mathematics and Natural Sciences, UNY, presented Dr. Nur Farhana Jaafar from Sultan Idris Education University, Malaysia, and Prof. Dr. Fitria Rahmawati from Sebelas Maret University, Indonesia.

The first material was delivered by Dr. Nur Farhana Jaafar on Image Mesoporrous Nanoparticles Photocatalyst for Degradation of Pollutants. As for Prof. Dr. Fitria delivered the second material on Materials for Electrochemical Energy Conversion and Storage. As many people know that the increase in CO2 emissions from burning fossil fuels globally is part of the description of the impact of global warming. This also has implications for floods, droughts, an increase in infectious diseases, and even a decrease in agricultural production, so that clean and environmentally friendly renewable energy is needed such as wind, sun, and even sea waves. Electrochemical cells can be an alternative because of 1) more specific reactions than combustion engines, 2) higher efficiency than combustion engines, 3) more flexible design, 4) quieter and less vibration, and 5) zero carbon emissions. Slowly, people can switch from fossil fuel combustion engines to energy conversions that are more environmentally friendly. Electrochemical energy conversion is a promising future technology.

With the implementation of the Webinar Series #5, it is hoped that it can be a learning tool to jointly prepare alternative energy that is more environmentally friendly. This will have an impact on future energy readiness to preserve the earth. Furthermore, the Department of Chemistry Education, Faculty of Mathematics and Natural Sciences, UNY still has Webinr Series #6, see you soon!
