I. Introduction
When the Covid-19 pandemic hit the entire world, many changes were put in place to prevent a massive spread [1]. One form of change must be made in learning activities, from faceto-face learning to online learning [2]. Even though onlinebased technology is very familiar in the community, its use for learning is minimal and causes several problems [3] [4]. Several online media are used in education by students and teachers in Indonesia, e.g., Whatsapp, Microsoft learning, or Google Classroom, Zoom, Skype, etc. [5]. These various applications have become familiar to use, even though previously they were not very popular.
