Improving Students' Critical Thinking Skills Against Environmental Problems: Practicum Mini Project "Understanding Public Perceptions of Environmental Problems"

The purpose of this research is to improve students' critical thinking skills towards environmental problems through mini-project practicum activities on the concept of understanding public perceptions of environmental problems. This research is descriptive research using a qualitative approach. The subjects in this study were Semester II class E students who took Environmental Science courses in the Even Semesters of the 2019/2020 Academic Year. The instrument used to measure critical thinking skills using indicators developed by Ennis are 1) Elementary, 2) Clarification Basic Support, 3) Inference, 4) Advanced Clarification, 5) Strategies and Tactics. Results The average critical thinking ability of 20 students is in the medium category (average score of 69.54). Of the 20 students, 10% were in the very high category, 30% in the high category, 25% in the medium category, and 35% in the low category. Indicators of students' critical thinking in 5 aspects, each of which has an average value that is in the medium category

Trends of Studies on Controlled Halogenated Gases under International Conventions during 1999–2018 Using Bibliometric Analysis: A Global Perspective

A lot of research on international convention-controlled halogenated gases (CHGs) has been carried out. However, few bibliometric analyses and literature reviews exist in this field. Based on 734 articles extracted from the Science Citation Index (SCI) Expanded database of the Web of Science, we provided the visualisation for the performance of contributors and trends in research content by using VOSviewer and Science of Science (Sci2). The results showed that the United States was the most productive country, followed by the United Kingdom and China. The National Oceanic and Atmospheric Administration had the largest number of publications, followed by the Massachusetts Institute of Technology (MIT) and the University of Bristol. In terms of disciplines, environmental science and meteorological and atmospheric science have contributed the most. By using cluster analysis of all keywords, four key research topics of CHGs were identified and reviewed: (1) emissions calculation, (2) physicochemical analysis of halocarbons, (3) evaluation of replacements, and (4) environmental impact. The change in research substances is closely related to the phase-out schedule of the Montreal Protocol. In terms of environmental impact, global warming has always been the most important research hotspot, whereas research on ozone-depleting substances and biological toxicity shows a gradually rising trend.

Integration of Environment and Content Knowledge into STEM Education

With a central focus on the research question: “What must be done to encourage people to become more E+STEM educated?” this research is based on a Systematic review on ecological knowledge, which is linked to teachers' career growth as well as Environmental Science, Technology, Engineering, and Mathematics (E+STEM) pedagogy. The aim is to identify what instructors must do to improve their experience and credentials as E+STEM-educated people in light of expert views. To disclose expert views, a "mixed method" research approach is utilized in this study, which includes both qualitative and quantitative techniques. The technique employed is exploratory study sequencing, which is a kind of mixed-method study. The Delphi study's initial stage is to gather qualitative data on teachers' professional growth. The quantitative methodology is featured for the phase two of the Delphi research once the data has been analyzed in the first step. Lastly, the ultimate quantitative formulation (third phase) is produced following the data evaluation in the second phase.

Excellency, Drs. Bedjo Santoso, MT. Ph. D., Rector Universitas Islam Sultan Agung; Honorable, Assoc. Prof. Dr. Mohd Ismid Bin Md Said, Pro-Vice Chancellor (International) UTM; Respectable, The distinguished guests and the participants, ladies and gentlemen. Welcome to the International Forum on Integrated Infrastructure Development (InFInID 2021) Hybrid Conference, which consists of 12th International Conference on Geotechnical Engineering in Tropical Regions (GEOTROPIKA), 2nd International Conference on Highway and Transportation Engineering (ICHITRA), and The 4th International Conference on Delta & Coastal Areas (ICCDA 4 2021), 21–22 September 2021. Due to the global health issue of coronavirus disease (COVID-19), InFInID 2021 is being held in mixed mode, offline and online. The conference is divided to Panel and Parallel session (7 parallel sessions, 3 rooms for 3 fields per session). I also want to inform that we will have ‘Best Paper’ Award for some topics and ‘Best Presenter’ Award for each session. For all presenters, do your best and catch the reward. The next step is publishing all paper to IOP Conference Series: Earth and Environmental Science, Scopus Index. May the conference run smoothly and the goals will be achieved. And last, but not least, I would like to thank you, our shareholders, for continuing to support us, in good times, and in difficult ones. Hope that the pandemic will leave us soon, and we will have the opportunity to meet again face to face. My best wishes to you all! Prof. Dr. Ir. S. Imam Wahyudi, DEA Chairman of ICCDA 4 List of Patrons, Advisors, Chairmen, Secretaries, Reviewer are avilable in this pdf.

Preface

Because of the travel restrictions between China and other countries of our keynote speaker, the 9th annual 2021 International Conference on Material Science and Environmental Engineering [MSEE2021] was held on November 27th, 2021 (Virtual Conference). The conference was held via Tencent Meeting Application. MSEE2021 aims to bring researchers, engineers, and students to the areas of Material Science and Environmental Engineering. MSEE2021 features unique mixed topics of Material Science and Advanced Materials, Material Engineering and Application, Environmental Science and Engineering and Mechanical Design and Technology. We received over 197 submissions from various parts of the world. The Technical Program Committee worked very hard to have all manuscripts reviewed before the review deadline. All the accepted papers have been submitted to strict peer-review, and selected based on originality, significance and clarity for the purpose of the conference. The conference program is extremely profound and featuring high-impact presentations of selected papers and additional late-breaking contributions. We sincerely hope that the conference would not only show the participants a broad overview of the latest research results on related fields, but also provide them with a significant platform for academic connection and exchange. There are two keynote speakers and four invited sessions. The keynote speakers are internationally recognized leading experts in their research fields, who have demonstrated outstanding proficiency and have achieved distinction in their profession. The proceedings would be published by IOP Journal of Physics Conference Series. We would like to express our sincere gratitude to all the members of Technical Program Committee and organizers for their enthusiasm, time, and expertise. Our deep thanks also go to many volunteers and staffs for the long hours and hard work they have generously given to MSEE2021. Last but not least, we would like to thank all the authors, speaker and participants for their great contributions to the success of MSEE2021.
