THE EFFECT OF PROJECT-BASED LEARNING MODEL ON STUDENTS’ WRITING IN DESCRIPTIVE TEXT ASSISTED WITH COMIC STRIPS AT GRADE XI OF SMA NEGERI 3 TANJUNGBALAI ACADEMIC YEAR 2025/2026

Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh model Pembelajaran Berbasis Proyek (PjBL) yang dibantu komik terhadap kemampuan menulis teks deskriptif siswa. Penelitian ini menggunakan metode kuantitatif dengan desain kuasi-eksperimental. Sampel terdiri dari dua kelas siswa kelas sebelas di SMA Negeri 3 Tanjung Balai tahun ajaran 2025/2026, yaitu kelas eksperimen dan kelas kontrol. Data dikumpulkan melalui pre-test dan post-test. Hasil penelitian menunjukkan bahwa nilai rata-rata kelas eksperimen pada pre-test adalah 62,2, sedangkan kelas kontrol adalah 57,6. Setelah perlakuan, kelas eksperimen meningkat sebesar 31% menjadi 81,5, sedangkan kelas kontrol meningkat sebesar 16% menjadi 66,8. Selanjutnya, hasil uji-t menunjukkan bahwa nilai t-observasi lebih tinggi daripada nilai t-tabel pada tingkat signifikansi 0,05. Ini berarti hipotesis alternatif (Ha) diterima dan hipotesis nol (Ho) ditolak. Kesimpulannya, model Pembelajaran Berbasis Proyek (PjBL) yang dibantu dengan komik memiliki pengaruh yang signifikan terhadap kemampuan menulis siswa dalam teks deskriptif.

This study aimed to determine the effect of the Project-Based Learning (PjBL) model assisted by comic strips on students’ writing ability in descriptive text. This research employed a quantitative method with a quasi-experimental design. The sample consisted of two classes of eleventh-grade students at SMA Negeri 3 Tanjung Balai in the 2025/2026 academic year, namely the experimental class and the control class.The data were collected through pre-test and post-test. The findings showed that the mean score of the experimental class in the pre-test was 62.2, while the control class was 57.6. After the treatment, the experimental class increased by 31% to 81.5, whereas the control class improved by 16% to 66.8. Furthermore, the result of the t-test indicated that the t-observed value was higher than the t-table value at the significance level of 0.05. This means that the alternative hypothesis (Ha) was accepted and the null hypothesis (Ho) was rejected. In conclusion, the Project-Based Learning (PjBL) model assisted by comic strips has a significant effect on students’ writing ability in descriptive text.
