Penelitian ini bertujuan untuk mengetahui pengaruh durasi penggunaan media sosial terhadap kemampuan menulis teks resensi pada siswa kelas XI-3A SMA Hang Tuah 4 Surabaya. Latar belakang dari penelitian ini berangkat dari fenomena meningkatnya penggunaan media sosial di kalangan remaja yang dikhawatirkan berdampak pada penurunan minat dan kualitas keterampilan menulis, khususnya dalam penulisan teks resensi yang menuntut kemampuan berpikir kritis dan sistematis. Penelitian ini menggunakan pendekatan kuantitatif deskriptif untuk menggambarkan hubungan antara durasi penggunaan media sosial dan kemampuan menulis siswa. Data dikumpulkan melalui dua instrumen, yaitu angket untuk mengetahui durasi harian penggunaan media sosial dan tes tulis untuk mengukur kemampuan siswa dalam menulis teks resensi. Tes menulis dievaluasi berdasarkan struktur, isi, kebahasaan, dan ketepatan penggunaan unsur-unsur resensi. Hasil penelitian menunjukkan bahwa sebagian besar siswa memiliki durasi penggunaan media sosial yang cukup tinggi, yakni lebih dari 4 jam per hari.

This study aims to determine the effect of the duration of social media use on the ability to write review texts in class XI-3A students of SMA Hang Tuah 4 Surabaya. The background of this study departs from the phenomenon of increasing social media use among teenagers which is feared to have an impact on decreasing interest and quality of writing skills, especially in writing review texts that require critical and systematic thinking skills. This study uses a descriptive quantitative approach to describe the relationship between the duration of social media use and students' writing skills. Data were collected through two instruments, namely a questionnaire to determine the daily duration of social media use and a written test to measure students' ability to write review texts. The writing test was evaluated based on structure, content, language, and the accuracy of the use of review elements. The results showed that most students had a fairly high duration of social media use, namely more than 4 hours per day. Meanwhile, students' ability to write review texts tended to vary, with some showing weaknesses in conveying opinions and analysis of the objects being reviewed. This finding indicates a tendency that the higher the duration of social media use, the lower the quality of review writing skills. Therefore, there needs to be better awareness and time management so that social media does not interfere with the development of students' literacy skills.
