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.

Investigation of Noise Pollution in an Educational Building – Case Study of Babylon University in Iraq

Acoustic conditions, considered an indicator of the level of comfort, are a major concern in educational facilities since they are linked to students’ well-being and learning capacity. In this study, measurements of the acoustical comfort conditions were performed using portable IEQ meter have been assessed in four selected areas of environmental engineering department building (The classroom for fourth year, student’s corridor, teacher’s corridor and reception area) in the University of Babylon in Hillah City. This was done by analyzing the data measured for 13 months from August (2020) to August (2021). Statistical analysis by using the linear regression test was performed to determine the relationship between the selected areas. Noise is the major parameter for the educational areas that can interfere with the students’ activities and eventually, this will have a detrimental effect on the students’ physical and psychological health. The acquired results were compared to the reference values specified in the handbook to international standards for noise compliance in academic educational facilities. The results show that all the studied areas in the Environmental Engineering Department had back-ground noise levels out of the recommended threshold limit values (>50 dB) revealed that the indoor environment of these areas was of poor quality, indicating the require for interventions. This study can be considered a pilot study for future comparable research on Iraqi universities.

Preface

The International Conference on Materials Chemistry and Environmental Engineering (CONF-MCEE 2021) The International Conference on Materials Chemistry and Environmental Engineering (CONF-MCEE 2021) is a leading conference, hosted by Eliwise Academy annually. It encourages communication and collaboration, hoping to provide an international platform for its participants to present, share, and learn the latest advance and development of materials, chemistry, and environmental engineering. Academics, researchers, and students from across the world are all welcomed to exchange findings and ideas to draw further inspirations in these research fields. It’s a great opportunity to deepen your understanding in the related topics. This volume contains the papers presented at the International Conference on Materials Chemistry and Environmental Engineering (CONF-MCEE 2021), held during November 11-16, 2021. Under the influence of COVID-19, the on-site conference was regretfully cancelled and CONF-MCEE was held online. For the safety concern of all participants, we decided to hold a virtual conference which is also effective and convenient for academic exchange and communication. Everyone interested in this field were welcomed to join the online conference on our YouTube channel and to give comments and raise questions to the speeches and presentations. We are hoping the pandemic to soon come to an end and we could see each other next year. CONF-MCEE 2021 received 179 submissions in the area of materials science and engineering, chemical science and technology, and environmental engineering. Each of the 179 submissions was reviewed by at least two Program Committee members. The committee decided to accept 64 papers that are included in these proceedings. We would like to thank the Program Committee members and external reviewers for their hard work in reviewing and selecting papers. Hopefully, all participants and other interested readers can benefit scientifically from the proceedings and find it rewarding in the process.

APPLICATION OF THE SELF-DIRECTED LEARNING (SDL) LEARNING MODEL IN ENVIRONMENTAL ENGINEERING COURSES FOR STUDENTS OF THE BUILDING ENGINEERING EDUCATION STUDY PROGRAM, UNIVERSITY OF PALANGKA RAYA, ACADEMIC YEAR 2020/2021

Teachers must work on learning assignments from home (continuously and as a controlled routine) on an ongoing basis and have the potential to be unproductive to work in a completely new environment and without the supervision of a leader (intense). However, there are a number of ways to deal with this problem, especially preventing teachers from being confused in applying appropriate and effective learning models, as well as continuous professional development, they definitely want to be productive in utilizing their time during the Covid 19 pandemic. Time management must be carried out and controlled properly to improve quality. teacher professionalism as a professional educator. The solution, teaching staff is required to be able to design learning media as an innovation by utilizing online media (online). This research is motivated by the learning outcomes of Building Engineering Education students who program Environmental Engineering Courses are still relatively low below a score of 60 (C value). Self-Directed Learning (SDL) is learning in which the conceptualization, design, implementation and evaluation of learning projects are directed by students. The key point is whether students choose to concentrate on learning. This type of research is classroom action research which is carried out online, this is due to the ongoing covid-19 pandemic. Quantitative data in the form of numbers or scores obtained from student learning outcomes tests. The instrument used in this research is the final test of student learning outcomes. The parameters in this study are the learning outcomes and independence of Building Engineering Education students in the Environmental Engineering course. Plans or targets will be published in the Balanga Journal.
