The research respondents were 592 students from 2 districts in the mountains of Aceh, namely Central Aceh and Bener Meriah. The results showed that high school students gave a poor perception of online learning; the learning media that students liked was the WhatsApp application. Students' loneliness causes this perception. Due to a lack of "social presence", social media as a learning medium is one solution to these problems, students choose social media to build a collaborative learning environment. Social media should be used as a learning medium, to reduce boredom due to lack of learning interaction.
