ABSTRACT
The emergence of COVID-19 pandemic has forced many countries implement social restrictions, including Indonesia. There has been a growing interest in understanding the impact of the pandemic on air quality. This research analyses the air pollution before and after the COVID-19 pandemic in Jakarta and Banjarmasin, Indonesia, with a detailed analysis. It compared the results with previous years to determine the significant improvement in air quality and related weather factors obtained from Landsat 8 and 9 imagery. OMI and MERRA-2 were analysed for PM2.5, NO2, SO2, O3 and WRF-Chem model result especially for PM2.5 against the COVID-19 pandemic. As a result, there was a decrease in PM2.5 during the pandemic year in Jakarta, although it was not as good as in 2016 conditions. In Jakarta and Banjarmasin, PM2.5, NO2 and SO2 decreased in 2021 from 2020, which were in line with the high incidence of COVID-19 in 2021. This shows that more air quality increased in the form of healthy days in DKI Jakarta in 2020 than in 2019. In other words, there was an increase in air quality during the implementation Large-Scale Social Restriction (PSBB) policy in 2020 compared to 2019 before the COVID-19 pandemic. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
Prophetic communication (PC) is an Islamic perspective with which to view everyday communication phenomena. While there are currently many negative aspects to the use of social media and the internet, online learning is highly useful for supporting the PC learning process-especially during the COVID-19 pandemic. Before the current pandemic, online learning was typically conducted in a blended manner with face-to-face meetings. However, this shifted during the pandemic, and PC learning was undertaken entirely online. Since the students themselves are one of the success factors of online learning implementation, it is important to examine the students' self-regulated learning skills in an online PC course throughout the semester. Quantitative and qualitative data were gathered from four classes. Data analyses were also conducted to address the research aim. The findings revealed that, overall, students apply self-regulated online learning skills. However, improvement and facilitation are still needed to enhance evaluation skills. From the qualitative data gathered, we constructed and categorized several themes into positive learning experiences, challenges, online learning strategies, and suggestions with which to improve online class management. © 2022 International Information and Engineering Technology Association.

ABSTRACT
The COVID-19 pandemic has changed the way learning is conducted in several countries. Face-to-face interaction has been prohibited to help prevent the spread of the virus even further. This situation has necessitated the transition from face-to-face to long distance learning. Lecturers' participation in using e-Learning platforms is one of the main factors that has influenced the transition. However, lecturers have faced many challenges during the transition period. Those challenges must be identified so that institutions can provide the support lecturers need. This study aims to identify the challenges and opportunities that come from online learning based on the lecturer’s perspective. A systematic literature review (SLR) is used to identify challenges and opportunities of online learning from previous studies. The findings of the current study show three major themes related to these challenges: individual, institutional, and technological. Furthermore, it finds that online learning provides opportunities to explore new ways of teaching and using technology for learning purposes, such as utilizing online learning tools for course assignments or quizzes. © 2021 IEEE
ABSTRACT
Chatbots are a highly developed technology, especially in the current COVID-19 pandemic to apply contactless activities. Unfortunately, most of companies that have been implemented chatbot has failed gained benefit from the chatbot. This shows companies need to evaluate usability of the chatbot. One of specific questionnaire to evaluate usability of chatbot is Chatbot Usability Questionnaire (CUQ). Currently CUQ is only available in English and there is no research that provides CUQ in the Indonesian version. This research focuses on translating CUQ and producing a reliable Indonesian version of CUQ. CUQ needs to be adapted naturally into Indonesian so it can be understood by all types of users. Cross-cultural adaptation approach is used to translate CUQ to Indonesia. The reliability test was run with 100 respondents and resulted in Cronbach's alpha value of 0.749. This value indicated that CUQ is reliable and can be used in chatbot research and evaluation. © 2021 IEEE
ABSTRACT
This study aims to analyze teacher and student responses to learning using the Learning Management System (LMS) during the COVID-19 pandemic. The respondents in this study were 100 teachers and students in Cilacap Regency, Central Java, Indonesia. 90% of respondents choose Google Classroom as the LMS they use. The information collection method used in this study was a survey with a questionnaire. The data obtained were then analyzed descriptively qualitatively by considering the aspects of the software used, content aspects and display aspects. The results of this study show that LMS helps online learning well during the COVID-19 Pandemic © 2021 IEEE.
ABSTRACT
The COVID-19 pandemic that occurred in early 2020 around the world has implications for Indonesia’s education sector. This pandemic led to the Indonesian government policy to study from home at all academic levels using a distance learning approach. Studies on e-learning preparedness in Indonesia involving more comprehensive samples of universities during the pandemic are still limited. This study extended samples from several public and private universities in Indonesia to get a broader picture of e-learning readiness in various faculties with diverse university online learning cultures. This study used Rasch analysis to determine the validity and reliability of the instrument and differential item functioning (DIF) analysis to identify responses based on students’ demographic profiles. The results show that most students were ready to study online, but a few were not ready. Moreover, the results show significant differences in students’ e-learning readiness based on the academic year at university, the field of study, the level of organizational e-learning culture of the university, gender, and region. This work provides an insight into student readiness to study online, especially in higher education in Indonesia. The article presents the implications of online learning practices in universities and recommendations for future e-learning research. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
ABSTRACT
Due to the COVID-19 pandemic, most educational institutions across the world have shifted their teaching and learning processes and put efforts into preparing online distance education to ensure education continues uninterrupted. Some did not face difficult tasks or challenges during this process because they were already implementing online or blended learning before the pandemic. However, some institutions, lecturers and students were not ready to adapt to the conditions, and it is therefore important to examine to what extent lecturers are ready to teach online. This research aims to evaluate the readiness of lecturers during a pandemic that arises unexpectedly. It also aims to investigate the weaknesses and obstacles that lecturers must overcome in order to teach an online class. This research applies a mixed-method approach. Lecturers were surveyed through online preparedness questionnaires, and several themes were constructed from the gathered qualitative data. The results show that lecturers have strong baseline technical skills to use e-learning platforms for online courses;they have quickly adapted to using a Learning Management System (LMS), and most have a tactical solution for most online classes with insufficient feasibility, but they do not have a strategic solution. Their sufficiency for teaching online courses was not optimised since they did not fully believe the learning goals could be achieved. This paper elaborates on the theoretical and practical implications. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.
ABSTRACT
Online examination gains popularity during the COVID-19 pandemic due to the massive adoption of online learning. In the online examination, human proctoring activity is hardly possible, and therefore an alternative way to keep academic integrity is needed. Currently, camera, microphone, and gyro sensors have been standard embedded sensors in smartphones. This research utilizes those sensors to detect the possibility of cheating in the online examination. A mobile application with two main functions was developed to record the user activity during the exam as the background and carryout the examination function on the foreground task. Consequently, users may feel uncomfortable dueto activity recording requirements. This research reveals many aspects of user convenience during the examination of varied user locations, available bandwidth, and gadgets. A user experience questionnaire plus (UEQ+) was used to understand user feelings while engaging with the application. Our analysis shows no strong correlation between key performance indicator achievement and the smartphone specification. According to the questionnaire analysis, the user considered that the secure exam application achieves 1.61 points in a range of -3 to 3. It is indicated that the users, in general,have a positive experience with the mobile exam application. © 2020 IEEE.
