PENGARUH PENERAPAN MODEL PEMBELAJARAN PROJECT-BASED LEARNING BERBANTUAN PERPLEXITY AI TERHADAP MOTIVASI DAN HASIL BELAJAR SISWA PADA MATA PELAJARAN IPS DI KELAS IX SMP MUHAMMADIYAH 2 TAMAN SIDOARJO

THE EFFECT OF THE APPLICATION OF THE PROJECT-BASED LEARNING MODEL ASSISTED BY PERPLEXITY AI ON STUDENTS' MOTIVATION AND LEARNING OUTCOMES IN SOCIAL SCIENCES IN GRADE IX OF SMP MUHAMMADIYAH 2 TAMAN SIDOARJO

Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model Project-Based Learning (PjBL) berbantuan aplikasi Perplexity AI terhadap motivasi dan hasil belajar siswa pada mata pelajaran Ilmu Pengetahuan Sosial (IPS). Penelitian ini menggunakan pendekatan kuantitatif dengan desain kuasi eksperimen tipe non-equivalent control group design. Subjek penelitian adalah siswa kelas IXA sebagai kelas eksperimen dan IXD sebagai kelas kontrol di SMP Muhammadiyah 2 Taman Sidoarjo pada semester genap tahun ajaran 2024/2025. Instrumen penelitian yang digunakan meliputi angket motivasi belajar dan tes hasil belajar (pre-test dan post-test). Selain itu, penilaian proyek mind map digunakan untuk mengukur keterlibatan siswa dalam proses pembelajaran berbasis proyek. Hasil analisis data menggunakan Independent Sample T-Test menunjukkan nilai signifikansi (Sig. 2-tailed) sebesar 0,000 < 0,05, yang berarti terdapat perbedaan yang signifikan antara kelompok eksperimen dan kontrol, baik dalam aspek motivasi maupun hasil belajar. Rata-rata skor post-test hasil belajar siswa kelas eksperimen adalah 85,1 dan motivasi belajar mencapai skor 71,8, lebih tinggi dibandingkan kelas kontrol. Siswa juga menunjukkan kualitas tinggi dalam produk proyek mind map, dengan rata-rata skor penilaian mencapai 91,3% (kategori sangat baik). Temuan ini membuktikan bahwa penerapan model PjBL berbantuan Perplexity AI berpengaruh positif dalam meningkatkan motivasi dan hasil belajar siswa IPS. Pembelajaran menjadi lebih aktif, kontekstual, dan sesuai dengan kebutuhan kompetensi abad ke-21.

This study aims to determine the effect of the implementation of the Project-Based Learning (PjBL) model assisted by the Perplexity AI application on student motivation and learning outcomes in Social Sciences (IPS) subjects. This study uses a quantitative approach with a quasi-experimental design of the non-equivalent control group design. The subjects of the study were students of grades IXA as the experimental class and IXD as the control class at SMP Muhammadiyah 2 Taman Sidoarjo in the even semester of the 2024/2025 academic year. The research instruments used included a learning motivation questionnaire and learning outcome tests (pre-test and post-test). In addition, a mind map project assessment was used to measure student engagement in the project-based learning process. The results of data analysis using the Independent Sample T-Test showed a significance value (Sig. 2-tailed) of 0.000 <0.05, which means there is a significant difference between the experimental and control groups, both in terms of motivation and learning outcomes. The average post-test score for students in the experimental class was 85.1, and their learning motivation reached 71.8, higher than the control class. Students also demonstrated high quality in their mind map project products, with an average assessment score of 91.3% (very good). These findings demonstrate that the implementation of the Perplexity AI-assisted PjBL model has a positive effect on improving the motivation and learning outcomes of social studies students. Learning becomes more active, contextual, and aligned with 21st-century competency requirements.
