This year, Journal of Environmental Science and Sustainable Development (JESSD) is proud to hold its fourth international virtual symposium, featuring world-class speakers and editors worldwide. We were incredibly honored to have invited Mohamad Nor Azra, Ph.D. from Head of Climate Change Adaptation Laboratory, Institute of Marine Biotechnology, Universiti Malaysia Terengganu (UMT), Prof. Dr.Arch. Iryna Bulakh from Darmstadt, Hesse, Germany, Dr. Ir. Haruki Agustina, M.Env.Eng.Sc. from Director of Contamination Restoration and Emergency Response of Hazardous Waste, Ministry of Environment and Forestry Indonesia, and Dr. Yuki M. A. Wardhana from Senior Vice President at PT Penjaminan Infrastruktur Indonesia (Persero).The symposium was held in a hybrid format, arranged online and offline, due to related restrictions during Covid-19 pandemic. I appreciate everyone’s participation in the fourth JESSD Symposium: International Symposium of Earth, Energy, Environmental Science, and Sustainable Development, despite the restrictive situation caused by the global Covid-19 pandemic. Instead of being postponed, this symposium was conducted hybridly in response to emerging issues mainly related to earth science, energy, environmental science, and sustainability. Moreover, this symposium also facilitates the publication of qualified research on Environment Sustainable after Covid-19 to contribute to the global response to the post-pandemic situation.This symposium is slightly different from the previous symposium and conference held last year. By making the best use of development in telecommunication platforms, we are able to gather virtually to share our insights and progress covering numerous subjects ranging from: the broad earth science, energy, and environmental science, and the special issues as well as Cleaner Production, Environmental Management and Protection, Environment during Post Covid-19, and Community Empowerment in Environmental Sectors. This symposium utilized Zoom and YouTube, a widely known cloud-based video conferencing tool, as its telecommunication platform.The symposium was held on 26-27 August 2023. Committees are based in School of Environmental Science, Universitas Indonesia, Jakarta, Indonesia. We are aware that a hybrid setup will not provide the same experience as an on-site symposium. However, it is in our nature as researchers to be undeterred by new challenges. The opportunity to host this event virtually allows us to facilitate cross-borders discussion and collaboration at lower cost and less impact on the environment through reducing carbon footprint. We have invited some prominent speakers from various regions to provide lectures on a wide range of environmental research. In addition, we have also invited world-class speakers and editors to help with your scientific publication process. The participants (presenters) come from 13 different countries all around the world, including: Iraq, Malaysia, Indonesia, Sri Lanka, Uzbekistan, Filipina, Jepang, Nigeria, China, Germany, Ukraine, Vietnam, Russia.List of committees, speakers are available in this Pdf.
