<![CDATA[This study examines the relationship between TikTok usage intensity and social interaction among Islamic Communication and Broadcasting (KPI) students at UIN Mahmud Yunus Batusangkar. Preliminary observations revealed that 100% of KPI students actively use TikTok, with 93.1% spending more than three hours daily and 95.8% reporting that TikTok usage disrupts their face-to-face social interaction. This study employed a quantitative correlational design with descriptive analysis. Using simple random sampling via Slovin's formula (10% margin of error), 74 respondents were drawn from 291 active KPI students. Data were collected through a four-point Likert scale questionnaire. Instrument validation via Pearson Product Moment correlation (n = 32; r-table = 0.349) yielded 9 valid items for Variable X and 19 valid items for Variable Y, with Cronbach's Alpha of 0.807 and 0.924 respectively. As Kolmogorov-Smirnov normality testing confirmed non-normal data distribution (p = 0.035), Spearman's rank correlation was applied as the primary inferential test. TikTok usage intensity was categorized as high (Grand Mean = 3.12), and social interaction also as high (Grand Mean = 2.79). Hypothesis testing revealed a significant negative relationship between the two variables (r = −0.244; p = 0.036), indicating that higher TikTok usage intensity is associated with lower social interaction quality. This study recommends that students manage social media usage time wisely to preserve the quality of face-to-face social interaction.]]>
