The rapid growth of social media among university students raises concerns regarding its impact on health, particularly sleep patterns. This research investigates the link involving social media usage intensity and students’ sleep patterns. A descriptive quantitative approach was employed through a survey method involving 30 active undergraduate students from various universities in Indonesia, using a survey based on Likert items. The analysis applied Pearson’s correlation to assess the intensity and orientation of the link between variables. The results revealed a strong and affirmative link between social media engagement and sleep pattern disturbances, indicated by a correlation score of 0.655. This reflects that greater intensity in using social media is associated with increased likelihood of disrupted sleep patterns, including irregular sleep schedules, reduced sleep duration, and decreased sleep quality. These findings emphasize the importance of better digital time management and educational interventions regarding healthy sleep habits, both for students and higher education institutions.  

The growth of digital technology and social media platforms has promoted intercultural communication, especially in second language acquisition by non-native speakers. This study examines phonological deviations in the Indonesian pronunciation of SunnyDahye, a South Korean influencer who frequently uses the language in her TikTok content. Employing a descriptive qualitative approach, data were collected from five purposively selected videos based on the clarity of audio and frequency of Indonesian usage. The analysis focused on segmental (consonants and vowels) and suprasegmental (intonation and stress) features using the International Phonetic Alphabet (IPA). Findings reveal notable instances of phonological interference, including the substitution of the alveolar trill /r/ with /l/, mispronunciations of the schwa vowel /ə/ replaced with /e/ or /a/, and flat intonation patterns influenced by Korean prosody. These deviations are rooted in the phonological system of the Korean language, which lacks certain Indonesian phonemes and prosodic features. The results emphasize the influence of first language phonology on second language articulation and underscore the importance of incorporating contrastive phonetic analysis in Bahasa Indonesia instruction for foreign learners. The study contributes to broader discussions in applied linguistics and second language pedagogy, particularly for the Indonesian for Foreign Speakers (BIPA) program.
