The purpose of this study was to determine the increase in mathematical problem solving abilities using the DPLS learning model with the Guided Discovery method based on Rubik's Cube media on the cube space building material for SMP N 4 Ungaran students.

This study uses classroom action research (CAR), with 2 cycles consisting of 4 stages of planning, implementation, observation and reflection. The population in this study was class VIII SMP Negeri 4 Ungaran for the academic year 2021/2022, class VIII-B obtained and became the research sample through a sampling technique, namely observation consisting of 34 students. Data collection techniques used observation sheets, post test tests, questionnaire sheets, documentation, and field notes. The analysis of the instrument trial used validity, rehabilitation, level of difficulty, and differentiating power.

The results of this study showed an increase in each cycle, in the first cycle the students who achieved the success indicator value 75 (T) were 25 students or 73.53% with an average value of 77.15. Meanwhile, the increase in the second cycle as many as 30 students reached the indicator or 88.24%, with an average value of 86.24, and the results of the student response questionnaire showed a percentage result of 81%, which means they strongly agree/like. The conclusion of the research: that the application of the DPLS learning model with the guided discovery method based on the rubric's cube media can improve the mathematical problem solving ability of class VIII B students of SMP N 4 Ungaran, on the material of building a cube space.

Abstrak

Tujuan penelitian ini adalah untuk mengetahui peningkatan kemampuan pemecahan masalah matematis dengan menggunakan model pembelajaran DPLS dengan metode Guided Discovery berbasis media Rubik's Cube pada materi bangunan ruang kubus pada siswa SMP N 4 Ungaran.

Penelitian ini menggunakan penelitian tindakan kelas (PTK), dengan 2 siklus yang terdiri dari 4 tahap perencanaan, pelaksanaan, observasi dan refleksi. Populasi dalam penelitian ini adalah siswa kelas VIII SMP Negeri 4 Ungaran tahun pelajaran 2021/2022, kelas VIII-B yang diperoleh dan menjadi sampel penelitian melalui teknik pengambilan sampel yaitu terdiri dari 34 siswa. Teknik pengumpulan data menggunakan lembar observasi, post test, lembar angket, dokumentasi, dan catatan lapangan. Analisis uji coba instrumen menggunakan validitas, rehabilitasi, tingkat kesukaran, dan daya pembeda.

Hasil penelitian ini menunjukkan adanya peningkatan pada setiap siklusnya, pada siklus I siswa yang mencapai nilai indikator keberhasilan 75 (T) sebanyak 25 siswa atau 73,53% dengan nilai rata-rata 77,15. Sedangkan peningkatan pada siklus II sebanyak 30 siswa mencapai indikator atau 88,24%, dengan nilai rata-rata 86,24, dan hasil angket respon siswa menunjukkan hasil persentase sebesar 81% yang berarti sangat setuju/suka. . Kesimpulan penelitian: bahwa penerapan model pembelajaran DPLS dengan metode penemuan terbimbing berbasis media rubrik kubus dapat meningkatkan kemampuan pemecahan masalah matematis siswa kelas VIII B SMP N 4 Ungaran, pada materi membangun kubus ruang angkasa.
