PENGARUH FREKUENSI PENGGUNAAN FILTER WAJAH TIKTOK TERHADAP TINGKAT SELF CONFIDENCE MURID PEREMPUAN SMPN 9 TEGAL

Abstract

ABSTRACT

The use of social media, particularly facial filter features on TikTok, has increasingly become common among adolescents and may be associated with self-perception and self-confidence. This study aimed to examine the effect of the frequency of facial filter use on TikTok on the level of self-confidence among female eighth-grade students at SMP Negeri 9 Tegal. This study employed a quantitative approach with an ex post facto design. The population consisted of 108 eighth-grade female students, while the sample comprised 73 students selected using purposive sampling based on the criteria of being active TikTok users and using facial filter features. Data were collected using psychological scales that met validity and reliability requirements, with Cronbach’s Alpha values of 0.935 for the facial filter use variable and 0.927 for the self-confidence variable. Data were analyzed using SPSS version 27 through descriptive analysis, classical assumption tests, simple linear regression, a partial t-test, and the coefficient of determination. The results showed that both the frequency of facial filter use and the students’ self-confidence were categorized as high. The partial t-test yielded a t-value of 8.210, which was greater than the t-table value of 1.994, with a significance value of 0.000 < 0.05, indicating that the alternative hypothesis was accepted. The coefficient of determination (R²) of 0.487 indicated that facial filter use contributed 48.7% to self-confidence, while the remaining 51.3% was influenced by other factors outside the study. Thus, the frequency of facial filter use on TikTok had a positive and significant effect on the self-confidence of female students
