      "note": "Penelitian ini bertujuan untuk mengetahui efektivitas dan pengaruh penerapan \r\nmodel pembelajaran Problem Based Learning (PBL) berbantuan ChatGPT \r\nterhadap kemampuan pemahaman konsep matematis siswa pada materi Sistem \r\nPersamaan Linear Dua Variabel (SPLDV) di SMPN 38 Kota Bekasi. Latar \r\nbelakang penelitian ini didasarkan pada rendahnya kemampuan pemahaman konsep \r\nsiswa yang teridentifikasi dari hasil belajar yang belum optimal, serta perlunya \r\nintegrasi teknologi kecerdasan buatan (Artificial Intelligence) untuk mengatasi \r\nhambatan belajar siswa secara personal. Penelitian ini menggunakan metode kuasi \r\neksperimen (quasi-experiment) dengan desain Nonequivalent Control Group \r\nDesign. Teknik pengumpulan data menggunakan instrumen tes berbentuk uraian \r\n(pretest dan posttest) yang telah teruji validitas dan reliabilitasnya. Teknik analisis \r\ndata menggunakan statistik deskriptif dan uji hipotesis non-parametrik Mann\r\nWhitney U. Hasil penelitian menunjukkan bahwa peningkatan pemahaman konsep \r\nmatematis siswa yang memperoleh pembelajaran dengan model PBL berbantuan \r\nChatGPT lebih tinggi secara signifikan dibandingkan dengan siswa yang \r\nmemperoleh pembelajaran dengan model PBL tanpa bantuan ChatGPT. Hal ini \r\ndibuktikan dengan rata-rata skor N-Gain kelas eksperimen yang termasuk dalam \r\nkategori tinggi, sedangkan kelas kontrol berada pada kategori rendah. Dengan \r\ndemikian, model PBL berbantuan ChatGPT terbukti efektif dalam mengakselerasi \r\npemahaman konsep matematis siswa.",

      "abstract": "This study aims to determine the effectiveness and influence of implementing the Problem-Based Learning (PBL) model assisted by ChatGPT on students' mathematical concept understanding of Systems of Linear Equations in Two Variables (SPLDV) at SMPN 38 Kota Bekasi. The background of this research is based on the low level of students' conceptual understanding identified from suboptimal learning outcomes, as well as the need for integrating Artificial Intelligence (AI) technology to overcome students' learning obstacles personally. This study employed a quasi-experimental method with a Nonequivalent Control Group Design. Data collection techniques used essay test instruments (pretest and posttest) that have been tested for validity and reliability. Data analysis techniques utilized descriptive statistics and the non-parametric Mann-Whitney U hypothesis test. The results indicated that the improvement in mathematical concept understanding of students who received learning with the ChatGPT-assisted PBL model was significantly higher compared to students who received learning with the PBL model without ChatGPT assistance. This is evidenced by the average NGain score of the experimental class, which falls into the high category, while the control class is in the low category. Thus, the ChatGPT-assisted PBL model is proven effective in accelerating students' mathematical concept understanding.",
