Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning berbantuan Media Flashcard Augmented Reality berbasis Assemblr edu terhadap Kemampuan Menulis Teks Deskripsi Siswa Kelas X SMA Negeri 2 Tanjungbalai. Metode penelitian yang digunakan adalah eksperimen dengan desain dua kelompok, yaitu kelas eksperimen dan kelas kontrol. Teknik pengumpulan data dilakukan melalui tes kemampuan menulis teks deskripsi (posttest). Analisis data menggunakan uji normalitas, homogenitas, dan uji Independent Samples t-test. Hasil penelitian menunjukkan nilai rata-rata posttest kelas kontrol sebesar 61,87, sedangkan kelas eksperimen sebesar 81,25. Nilai signifikansi 0,001 < 0,05 menunjukkan adanya pengaruh signifikan penerapan model pembelajaran Problem Based Learning berbantuan media Flashcard Augmented Reality berbasis Assemblr edu terhadap kemampuan menulis teks deskripsi siswa. Dengan demikian, model pembelajaran Problem Based Learning berbantuan media Flashcard Augmented Reality berbasis Assemblr edu efektif digunakan dalam pembelajaran Bahasa Indonesia pada materi menulis teks deskripsi. Hasil uji hipotesis menunjukkan bahwa nilai t hitung (12,11) lebih besar daripada t tabel pada taraf signifikan 5% (2,00) dan 1% (2,65), sehingga hipotesis nihil (Ho) ditolak dan hipotesis alternatif (Ha) diterima. Dengan demikian, dapat disimpulkan bahwa model Problem Based Learning berbantuan Media Flashcard Augmented Reality berbasis Assemblr edu berpengaruh signifikan terhadap kemampuan menulis teks deskripsi siswa. Model dan media ini mampu meningkatkan kemampuan siswa dalam aspek struktur teks, isi, kaidah kebahasaan, serta penggunaan ejaan dan tanda baca, sehingga pembelajaran menjadi lebih aktif, kreatif, dan menyenangkan.

This study aims to determine the effect of the Problem Based Learning model assisted by Flashcard Augmented Reality media based on Assemblr edu on the ability to write descriptive texts of Grade X students at SMA Negeri 2 Tanjungbalai. The research method used is experimental with a two-group design, namely the experimental class and the control class. Data collection techniques were conducted through a descriptive text writing ability test (posttest). Data analysis used normality test, homogeneity test, and Independent Samples t-test. The results of the study showed that the average posttest score of the control class was 61.87, while the experimental class was 81.25. The significance value of 0.001 < 0.05 indicates a significant effect of the implementation of the Problem Based Learning model assisted by Flashcard Augmented Reality media based on Assemblr edu on students' ability to write descriptive texts. Thus, the Problem Based Learning model assisted by Augmented Reality Flashcard media based on Assemblr edu is effective for learning Indonesian in the material of writing descriptive texts. The hypothesis test results showed that the calculated t value (12.11) is greater than the t table at a 5% significance level (2.00) and 1% (2.65), so the null hypothesis (Ho) is rejected and the alternative hypothesis (Ha) is accepted. Therefore, it can be concluded that the Problem Based Learning model assisted by Augmented Reality Flashcard media based on Assemblr edu has a significant effect on students' ability to write descriptive texts. This model and media can improve students' abilities in aspects of text structure, content, language rules, as well as the use of spelling and punctuation, making learning more active, creative, and enjoyable.
