One of the Best Private Universities in Central Java, namely Dian Nuswantoro University, helped build a distance learning system, namely KULINO, which is a Moodle-based Learning Management System (LMS) in overcoming the Covid-19 Pandemic situation. This research aims to discover the social interactions that occur in online learning using KULINO. This study uses a qualitative research method with a phenomenological approach. Research results show interaction between students and lecturers in synchronous learning is more interactive. In contrast, the asynchronous learning interactions run in one direction so education is not interactive. The form of social interaction in online learning is associative in the form of cooperation and assimilation, while the form of dissociative interaction is in the form of conflict in the task group. Learning that is synchronously intertwined is more interactive, althought it must still be combined with asyncronous. Suggestions that can be given are that lecturers should be able to build interesting situations so that students are not bored and passive during online lectures.
