ABSTRACT
Polymeric materials are used for personal protective equipment (PPE), which is mandatory for clinicians to use when handling coronavirus disease 2019 (COVID-19) patients. The development of diagnostic tools and vaccines for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is also dependent on polymer technology. This current report aims to provide readers with the trend of polymer research regarding the COVID-19 pandemic, by employing bibliometric analysis. A literature search on the Scopus database (31 January 2022) was carried out using predetermined terms. Using Scopus database features, the publications were filtered based on the year of publication (2020-2022), types of articles (original research and review), and language (English). The metadata were extracted in a CSV (.csv) file, to be later used in VOSviewer software. The data were presented in a table, graph, and network visualization. As many as 512 publications were included, consisting of 66.4% original research articles and 33.6% review articles. Most of the publications were written by authors whose affiliation was in the United States (n = 118, 23%) and covering the Materials Science subject area (n = 142, 27.7%). The Ministry of Education of China was the most productive organization, publishing 11 articles. The National Science Foundation of China was the top funding source, supporting 45 publications. Heinz C. Schröder was the most prolific author, publishing nine articles. Science of the Total Environment was the leading journal publishing the included studies. The trend of polymer technology related to COVID-19 mostly covers PPE and waste-management themes. The use of polymer technology as a delivery system for the anti-SARS-CoV-2 and COVID-19 vaccine is also among the frequently researched areas. We encourage more research in the field of polymer technology be carried out, to overcome the global pandemic.
ABSTRACT
The implementation of learning has undergone significant changes due to the Coronavirus (COVID-19) spreading rapidly so that the teaching and learning process at various levels of education is generally carried out online. This urges lecturers to adapt teaching materials to online learning systems, especially subject topics that require laboratory activities. This study aims to develop an e-module for basic chemistry practice courses not only containing material and quizzes but also integrates practical video tutorials in each of its sub-topics. The research method used is research and development (R D) by applying the ADDIE model. Research respondents were 58 students of the Physics Education FKIP USK enrolled in basic chemistry practice courses in their first-year study in the 2019-2020. The research data were collected using instruments in the form of students’ responses to the questionnaire on 1) the e-module, and 2) the application of e-modules in basic chemistry laboratory courses. The questionnaires were distributed via Google form to avoid physical contact and comply with health protocols. Prior to distribution, the questionnaire was tested for validity and reliability using the Cronbach's alpha test and analyzed with SPSS version 12 (IDMTM). The results of the validation show that the mean value of validation is 91.48% for the display, content, grammar, and evaluation system items. Cronbach's alpha test shows a mean alpha value of 0.903. The results of the response questionnaire showed that the average response score was greater than 8.00 for each questionnaire item, while the mean score for the application of the e-module laboratory courses was 8.88. This shows that the e-module for basic chemistry lab work is favorable and suitable for use as teaching material in the online learning process.
