<![CDATA[The rapid growth of TikTok usage among adolescents has become an important issue due to its potential influence on students' character development. This study aims to examine the effect of TikTok social media use on the politeness character of tenth-grade students at SMAN 1 Giri Banyuwangi. The research employed a quantitative approach using a survey method. The population consisted of 360 students, while 80 respondents were selected through proportional random sampling. Data were collected using questionnaires, observations, and documentation. Prior to hypothesis testing, the research instrument was tested for validity and reliability, followed by normality and linearity tests. Data were analyzed using descriptive statistical analysis and inferential statistical tests with the aid of SPSS version 26 after the research instrument met the validity, reliability, normality, and linearity assumptions. The results showed that all questionnaire items were valid and reliable (Cronbach's Alpha = 0.922). The data were normally distributed (Asymp. Sig. = 0.200 > 0.05), and the hypothesis test indicated that TikTok social media use significantly affected students' politeness character (t = 2.518; Sig. = 0.014 < 0.05). However, the coefficient of determination (R² = 0.075) revealed that TikTok social media use contributed 7.5% to students' politeness character, while the remaining 92.5% was influenced by other factors outside this study. This study contributes to strengthening empirical evidence regarding the relationship between social media use and character education in the digital era, while providing practical recommendations for schools, teachers, and parents to improve students' digital literacy and character development.]]>
