<![CDATA[ABSTRACT Poetry writing instruction in schools continues to face several challenges, including students' low learning motivation, difficulties in generating ideas, and the use of instructional media that are insufficiently aligned with the characteristics of today's digital generation. This study aimed to describe teacher activities, student activities, and students' poetry writing achievement through the implementation of TikTok as an instructional medium at SMK NU 1 Sukodadi Lamongan. The study employed a quantitative descriptive approach involving one Indonesian language teacher and 32 tenth-grade students. Data were collected through classroom observations, poetry writing performance tests, and documentation, and were analyzed using descriptive statistics, including percentages and mean scores. The findings revealed that teacher activities achieved a percentage of 97.5%, which was categorized as excellent, while student activities were also classified as excellent, as reflected in their high level of participation throughout the learning process. The average score of students' poetry writing achievement was 84.56, with a classical learning mastery rate of 96.88%, indicating that almost all students successfully met the Minimum Mastery Criteria (MMC). These findings demonstrate that the use of TikTok supports a more interactive, creative, and student-centered learning process while improving students' poetry writing skills. This study provides empirical evidence that TikTok has considerable potential as an effective digital learning medium for Indonesian language instruction, particularly in teaching poetry writing at the vocational high school level.

Penelitian ini bertujuan mendeskripsikan aktivitas guru, aktivitas siswa, dan hasil belajar menulis puisi melalui pemanfaatan aplikasi TikTok sebagai media pembelajaran di SMK NU 1 Sukodadi Lamongan. Penelitian menggunakan pendekatan deskriptif kuantitatif dengan subjek seorang guru Bahasa Indonesia dan 32 siswa kelas X. Data diperoleh melalui observasi, tes praktik menulis puisi, dan dokumentasi, kemudian dianalisis menggunakan statistik deskriptif berupa persentase dan nilai rata-rata. Hasil penelitian menunjukkan bahwa aktivitas guru mencapai persentase 97,5% dengan kategori sangat baik, sedangkan aktivitas siswa juga berada pada kategori sangat baik yang ditunjukkan oleh tingginya keterlibatan selama proses pembelajaran. Nilai rata-rata kemampuan menulis puisi siswa mencapai 84,56 dengan ketuntasan belajar klasikal sebesar 96,88%, menunjukkan bahwa hampir seluruh siswa berhasil memenuhi Kriteria Ketuntasan Minimal (KKM). Temuan ini membuktikan bahwa pemanfaatan TikTok mampu mendukung proses pembelajaran yang lebih interaktif, kreatif, dan berpusat pada siswa, sekaligus meningkatkan kemampuan menulis puisi. Penelitian ini memberikan bukti empiris bahwa TikTok berpotensi menjadi media pembelajaran digital yang efektif untuk mendukung pembelajaran Bahasa Indonesia, khususnya pada materi menulis puisi di jenjang SMK.]]>
