Penelitian ini didasari oleh rendahnya kemampuan pemecahan masalah matematis peserta didik pada materi Sistem Persamaan Linear Dua Variabel (SPLDV) yang salah satunya disebabkan oleh bahan ajar yang kurang menunjang proses pembelajaran. Tujuan penelitian ini untuk mengembangkan lembar kerja peserta didik (LKPD) berbasis kearifan lokal Kabupaten Kuningan untuk memfasilitasi kemampuan pemecahan masalah matematis sesuai dengan prosedur model pembelajaran problem based learning yang memenuhi kriteria valid, praktis, dan efektif. Jenis penelitian yang digunakan adalah penelitian Research and Development (R&D) dengan menggunakan model pengembangan ADDIE (analysis, design, development, implementation, and evaluation). Subjek uji coba yaitu peserta didik kelas VIIIC SMP Negeri 2 Cibeureum yang berjumlah 13 peserta didik. Instrumen pengumpulan data yang digunakan adalah pedoman observasi, pedoman wawancara, lembar validasi ahli, angket respon peserta didik dan guru, dan soal posttest. Teknik analisis data yang digunakan yaitu analisis deskriftif kualitatif. Berdasarkan hasil validasi LKPD diperoleh rata-rata skor ahli materi adalah 86% dengan kriteria sangat valid. Sedangkan rata-rata skor ahli media adalah 79% dengan kriteria valid. Kriteria kepraktisan memperoleh skor rata-rata dari respon guru yaitu sebesar 89% dengan kategori sangat praktis. Sedangkan rata-rata skor kepraktisan dari respon peserta didik yaitu sebesar 93% dengan kategori sangat praktis. Keefektifan diperoleh dari hasil ketuntasan klasikal yaitu sebesar 92% dengan kategori efektif. Berdasarkan hasil tersebut dapat disimpulkan bahwa LKPD yang dikembangkan memenuhi kriteria valid, praktis, dan efektif sehingga dapat digunakan dalam pembelajaran. Peneliti selanjutnya diharapkan dapat melakukan uji coba secara luas.

This research is based on the low mathematical problem solving abilities of students in the System of Linear Equations in Two Variables (SPLDV) material, one of which is caused by teaching materials that do not support the learning process. The aim of this research is to develop student worksheets (LKPD) based on local wisdom in Kuningan District to facilitate mathematical problem solving abilities in accordance with problem based learning model procedures that meet the criteria of valid, practical and effective. The type of research used is Research and Development (R&D) research using the ADDIE development model which consists of 5 stages, namely analysis, design, development, implementation, and evaluation. The test subjects were 13 students in class VIIIC of SMP Negeri 2 Cibeureum. The data collection instruments used were observation guidelines, interview guidelines, expert validation sheet questionnaires, student and teacher response questionnaires, and posttest questions. The data analysis technique used is qualitative descriptive analysis. Based on the results of the LKPD validation, the average material expert score was 86% with very valid criteria. Meanwhile, the average score of media experts is 79% with valid criteria. The practicality criterion obtained an average score from teacher responses, namely 89% in the very practical category. Meanwhile, the average practicality score from student responses was 93% in the very practical category. Effectiveness is obtained from the results of classical completion, namely 92% in the effective category. Based on these results, it can be concluded that the LKPD developed meets the criteria of being valid, practical and effective so that it can be used in learning. It is hoped that future researchers will be able to carry out extensive trials.
