Lack of direct interaction with people in the surrounding environment and lack of concern for people in the surrounding environment and students are exposed to a lot of useless, negative content on the TikTok application, which some people consider to be part of entertainment as a means of showing off to follow current trends so that many posts lower the morals of students due to the lack of guidance from those closest to them. 2).
