Preface

This year, Journal of Environmental Science and Sustainable Development (JESSD) is proud to hold its first international virtual symposium, featuring world-class speakers and editors worldwide. We were incredibly honored to have invited Prof. Shabbir H Gheewala, D. Eng. from King Mongkut’s University of Technology Thonburi, Thailand; Mari E. Mulyani, D.Phil. from University of Oxford, United Kingdom; Dr. Stefanie Steinebach from HAWK-HHG (Hochschule für angewandte Wissenschaft und Kunst-Hildesheim/Holzminden/Göttingen), Germany; Prof. Dr. Ing. Ir. Misri Gozan, M.Tech. from Universitas Indonesia, Indonesia; Assoc. Prof. Dr. Marlia Mohd Hanafiah from Universiti Kebangsaan Malaysia, Malaysia; Ian D. Hollingsworth, Ph.D. from Horizon Environmental Soil Survey and Evaluation Darwin, Australia; Nurdiana Darus from Unilever Indonesia; Dr. Ir. Haruki Agustina, M. Env Eng. Sc. From Director for Contamination Recovery and Emergency Response of Hazardous Waste, KLHK Indonesia; Dr. Yuki M. A. Wardhana from School of Environmental Science UI and Indonesia Infrastructure Guarantee Fund-IIGF/PT Penjaminan Infrastruktur Indonesia-Persero, Indonesia; Prof. Ir. Widjojo Adi Prakoso, M.Sc., Ph.D from Faculty of Engineering, Universitas Indonesia;. Dr Karen Lythgoe from Earth Observatory of Singapore; Walter Mooney Ph.D from U.S. Geological Survey, USA and Dr. Supriyanto Rohadi Center for Research and Development Center, BMKG (Indonesian Agency for Meteorology Climatology and Geophysics), Indoneia. The symposium was held in virtual format due to related restrictions during COVID-19 pandemic. I appreciate everyone’s participation in the first 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 virtually to response to emerging issues mainly related to earth science, energy, environmental science, and sustainability. Moreover, this symposium also facilitates the publications of qualified research on COVID-19 to contribute to the global response towards the pandemic situation. This symposium is slightly different with 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 progresses covering numerous subjects ranging from: the broad earth science, energy, and environmental science, to more specific topics on Sustainable Development Goals (SDGs), and the special issues of COVID-19 Research as well as Community Engagement for Better Environment. This symposium utilized Zoom, a widely known cloud-based video conferencing tool, as its telecommunication platform. The symposium was held on 28–30 September 2020. Committees are based in School of Environmental Science, Universitas Indonesia, Jakarta, Indonesia. The symposium consists of plenary sessions and parallel sessions. The plenary sessions include keynote speech from various experts in related fields. The topics of the plenary sessions are considered purposeful in today’s agenda, such as life cycle assessment of biofuels, environmental governance in developing countries, smallholder palm oil and sustainability, collaborative scheme of solid waste management, alternative financing for waste management, plastic recycling, disaster management, and many more. Meanwhile, the parallel sessions facilitate the authors/presenters to discuss about their research in a smaller group based on the topic grouping. Each author/presenter was given up to 9 minutes for presentation and 3 minutes for question and answer. Quick questions were addressed right after each presentation, but longer questions were compiled and discussed at the end of the session. The session was wrapped up by the moderator in his/her closing remarks. The participants (presenters) are coming from 25 different countries all around the world, including: Indonesia, India, Japan, Bulgaria, Russian Federation, Ukraine, Pakistan, Poland, Colombia, Iran, Romania, United Arab Emirates, Malaysia, Finland, Vietnam, Philippines, Nigeria, Sri Lanka, Netherlands, Morocco, Thailand, United Kingdom, Republic of Tajikistan, Brazil, and Ethiopia. Participant (presenter) numbers are 270. We are glad that we received lots of submissions from the symposium and selected a bunch of high-quality papers and compiled them into the proceedings after reviewed them using the double-blind peer review procedure. The symposium is considered successful. Signal loss and some technical issues happened during parallel sessions but had been well and quickly addressed by technical assistants, without causing any significant delay. I express my deep gratitude to the Chairman, all distinguished keynote speakers, committees, reviewers, and all the participants, for their time, hard work, and contribution to support this symposium during this challenging time. I would like to take this opportunity also to express my gratitude for our sponsors, Bank Rakyat Indonesia (BRI), PT Unilever Indonesia Tbk, and PT Larus Birus Utama, for sponsoring the main events, as well as APIKI Indonesia Network (Jaringan Ahli Perubahan Iklim dan Kehutanan Indonesia) and BMKG (Badan Meteorologi, Klimatologi, dan Geofisika) for conducting the joined session. Last but not the least, we send our sincere thanks to the IOP publisher for publishing the proceedings.
