The purpose of this study was to produce a contextual-based Student Worksheet (LKPD) which was developed with the Logan Avenue Problem Solving (LAPS)?Heuristic model oriented to students' mathematical problem solving abilities that were valid, practical, and effective. The type of research carried out is Research and Development using a research model according to Borg and Gall with a one group pretest posttest design. Data analysis techniques include interviews, questionnaires, observations and tests. The results of the analysis show that first, the contextual-based LKPD development design with the LAPS?Heuristic model is oriented towards mathematical problem solving abilities and has valid and practical criteria. Second, the average gain of students' mathematical problem solving abilities using contextual-based worksheets with the LAPS?Heuristic test model (N-gain) ? 0.71 and the t test obtained is 5.328 {\ensuremath{>}} 2.160, so that contextual-based worksheets with the LAPS?Heuristic model are effective in improving students' mathematical problem solving abilities.

ABSTRAK
Tujuan penelitian ini adalah untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) berbasis kontekstual yang dikembangkan dengan model Logan Avenue Problem Solving (LAPS)?Heuristic berorientasi pada kemampuan pemecahan masalah matematis peserta didik yang valid, praktis, dan efektif. Jenis penelitian yang dilakukan adalah Research and Development dengan menggunakan model penelitian menurut Borg dan Gall dengan desain one grup pretest posttes. Teknik analisis data diantaranya wawancara, angket, observasi dan tes. Hasil analisis menunjukkan bahwa pertama, desain pengembangan LKPD berbasis kontekstual dengan model LAPS?Heuristic berorientasi pada kemampuan pemecahan masalah matematis memiliki kriteria valid dan praktis. Kedua, rata-rata gain kemampuan pemecahan masalah matematis siswa menggunakan LKPD berbasis kontekstual dengan model LAPS?Heuristic uji (N-gain) ? 0,71 dan uji t diperoleh 5,328 {\ensuremath{>}} 2,160, sehingga LKPD berbasis kontekstual dengan model LAPS?Heuristic efektif dalam meningkatkan kemampuan pemecahan masalah matematis siswa}
