Pengabdian ini tentang penerapan model pembelajaran berbasis proyek (Project Based Learning) terhadap hasil belajar matematika dengan tujuan untuk mengetahui (1) hasil belajar matematika peserta didik yang diajar tanpa menggunakan model pembelajaran berbasis proyek (2) hasil belajar matematika peserta didik yang diajar dengan menggunakan model pembelajaran berbasis proyek (3) apakah penerapan model pembelajaran berbasis proyek efektif dalam meningkatkan hasil belajar matematika pada peserta didik kelas IX MTs Madani Alauddin Paopao Kabupaten Gowa. Penelitian ini merupakan jenis penelitian eksperimen dengan menggunakan desain penelitian Quasi Experimental Design dengan bentuk Nonequivalent Control Groups Design. Populasi dalam penelitian ini adalah seluruh peserta didik kelas IX MTs Madani Alauddin Paopao Kabupaten Gowa terdiri dari 48 peserta didik sedangkan sampelnya adalah keseluruhan dari populasi yaitu kelas IXA sebagai kelas eksperimen dan siswa kelas IXB sebagai kelas kontrol yang masing-masing terdiri dari 25 peserta didik dan 23 peserta didik dan dikategorikan dalam tekenik sampling jenuh. Instrumen yang digunakan dalam penelitian ini adalah tes hasil belajar siswa, berupa pretest-posttest dan lembar observasi. Teknik analisis yang digunakan adalah analisis statistik deskriptif dan analisis statistik inferensial. Hasil analisis statistik deskriptif diperoleh rata-rata post-test kelas eksperimen 82,5 dan rata-rata post-test kelas kontrol 72,59. Sedangkan hasil analisis inferensial disimpulkan bahwa penerapan model pembelajaran berbasis proyek efektif dalam meningkatkan hasil belajar matematika pada peserta didik kelas IX MTs Madani Alauddin Paopao Kabupaten Gowa.

Abstract
This research is about the effectiveness of the application of project-based learning models (Project Based Learning) on mathematics learning outcomes with the aim of knowing (1) mathematics learning outcomes of students being taught without using project-based learning models (2) mathematics learning outcomes of students being taught using project-based learning model (3) whether the application of the project-based learning model is effective in improving mathematics learning outcomes in class IX students of MTs Madani Alauddin Paopao, Gowa Regency. This research is a type of experimental research using a Quasi Experimental Design research design in the form of Nonequivalent Control Groups Design. The population in this study were all students of class IX MTs Madani Alauddin Paopao, Gowa Regency consisting of 48 students while the sample was the whole population, namely class IXA as the experimental class and class IXB students as the control class, each of which consisted of 25 students and 23 students and categorized in saturated sampling technique. The instrument used in this study was a test of student learning outcomes, in the form of a pretest-posttest and observation sheets. The analysis technique used is descriptive statistical analysis and inferential statistical analysis. The results of the descriptive statistical analysis showed that the post-test average for the experimental class was 82.5 and the post-test average for the control class was 72.59. While the results of inferential analysis in testing the data hypothesis show that the t-count value is greater than the t-table value (3.25> 2.01) and the average learning outcomes of the experimental class are higher than the average learning outcomes of the control class, thus it can be concluded that the application of project-based learning models is effective in improving mathematics learning outcomes in class IX students at MTs Madani Alauddin Paopao, Gowa Regency.
