I. Introduction
In March 2020, COVID-19 was declared by World Health Organization (WHO) a global pandemic. In the same month, the first cases in Indonesia also were also reported. Not long after that, the Indonesian Ministry of Education, Culture, Research, and technology called for immediate closure all schools and higher education institutions in order to suppress the COVID-19 spread, thus the remote learning modalities were implemented, teaching and learning were shifted to distance home-based learning [1]. The COVID-19 pandemic has led to an increase in digital learning platform use. There are various types of digital platforms which popularly used in educational settings in Indonesia during pandemics, namely: instant messaging platforms (e.g., WhatsApp, telegram), web-based video meeting platforms including Google meet, Zoom, and Microsoft Teams, as well as educational technology (ed-tech) platforms such as Rumah Belajar [2], Moodle and Google Classroom.
