Abstrak Penelitian ini dilatarbelakangi oleh hasil temuan tentang permasalahan hasil belajar pada mata pelajaran informatika dan ditemukannya model pembelajaran yang diguanakan masih bersifat konvensional. Tujuan penelitian ini yaitu mengetahui Pengaruh Model Pembelajaran Cooperative Student Teams Actievement Divison (STAD) terhadap hasil belajar siswa pada mata pelajaran Informatika di Kelas X TKJ SMK Negeri 1 Bokat. Penelitian ini menggunakan pendekatan kuantitatif dengan model quasi eksperimen, Sampel dalam penelitian ini adalah kelas X TKJ SMK Negeri 1 Bokat yang berjumlah 50 siswa, terdiri dari kelas kontrol 25 siswa dan kelas eksperimen 25 siswa. Teknik pengumpulan data meliputi pre-test, perlakuan, kemudian post test. Hasil belajar siswa pada kelas kontrol Skor Pre-Test rata-rata adalah 47.20, Skor Post-Test rata-rata meningkat menjadi 52.20. pada kelas Eskperimen skor Pre-Test rata-rata adalah 68.40, skor Post-Test rata-rata meningkat tajam menjadi 85.80. Peningkatan skor post-test di kelas eksperimen 17.40 poin jauh melampaui peningkatan di kelas kontrol 5,00, menunjukkan dampak positif yang dari Model STAD. Hasil uji hipotesis menggunakan Wilcoxon Signed Rank Test menunjukkan bahwa nilai Asymp. Sig. (2-tailed) sebesar 0,000 (< 0,05). Hal ini mengindikasikan bahwa terdapat perbedaan yang signifikan antara nilai pretest dan posttest pada kelompok eksperimen, serta antara kelompok kontrol dan eksperimen. Dengan demikian, H0 ditolak dan Ha diterima, artinya penerapan model pembelajaran STAD berpengaruh signifikan terhadap peningkatan hasil belajar siswa. Kata kunci: Hasil Belajar; Model STAD; Informatika Abstract This study was motivatedby findings regarding learning outcomes in computer scienceand the discovery that the learning model used was still conventional. The purpose of this study was to determine the effect of the Cooperative Student Teams Achievement Division (STAD) learning model on student learning outcomes in Informatics in Class X TKJ at SMK Negeri 1 Bokat. This study used a quantitative approach with a quasi-experimental model. The sample in this study was class X TKJ SMK Negeri 1 Bokat, consisting of 50 students, comprising a control class of 25 students and an experimental class of 25 students. Data collection techniques included pre-tests, treatment, and post-tests. The learning outcomes of students in the control class had an average pre-test score of 47.20, and the average post-test score increased to 52.20. In the experimental class, the average pre-test score was 68.40, and the average post-test score increased sharply to 85.80. The increase in the post-test score in the experimental class of 17.40 points far exceeded the increase in the control class of 5.00, indicating a positive impact of the STAD model. The results of the hypothesis test using the Wilcoxon Signed Rank Test showed that the Asymp. Sig. (2-tailed) value was 0.000 (< 0.05). This indicates that there is a significant difference between the pretest and posttest scores in the experimental group, as well as between the control and experimental groups. Thus, H0 is rejected and Ha is accepted, meaning that the application of the STAD learning model has a significant effect on improving student learning outcomes.
