Karakter demokratis dan kemampuan pemecahan masalah siswa masih rendah dan kurang mendapat perhatikan dalam penerapan matematika. siswa tidak aktif mengikuti kegiatan diskusi, cenderung diam dan siswa masih kesulitan dalam memecahkan masalah yang disebabkan kurangnya kepercayaan diri dan kurang kreatif. salah satu upaya untuk mengembangkan karakter demokratis dan meningkatkan kemampuan pemecahan masalah siswa adalah dengan pendekatan realistic mathematics education (rme). penelitian ini bertujuan 1) menganalisis karakter demokratis siswa selama proses pembelajaran melalui rme; 2) mengetahui peningkatan kemampuan pemecahan masalah siswa setelah mengikuti pembelajaran melalui pendekatan rme; dan 3) menganalisis kemampuan pemecahan masalah ditinjau dari karakter demokratis siswa. jenis penelitian ini adalah penelitian kuantitatif deskriptif dengan desain penelitian pre-experimenal design. sampel penelitian adalah siswa kelas viii yang berjumlah 45 orang siswa. instrumen yang digunakan pada penelitian penelitian ini yaitu lembar observasi karakter demokratis, tes awal (pretest) dan tes akhir (post test) kemampuan pemecahan masalah. analisis data observasi karakter demokratis harian siswa menggunakan rubrik penilaian karakter demokratis siswa. hasil pretest- post test dianalisis dengan uji t berpasangan lalu peningkatannya melalui n-gain, dan selanjutnya data karakter demokratis dan kemampuan pemecahan masalah diberi katagori. hasil penelitian menunjukkan bahwa 1) perkembangan karakter demokratis siswa selama proses pembelajaran dengan pendekatan rme mengalami peningkatan; 2) terdapat peningkatan kemampuan pemecahan masalah siswa setelah mengikuti pembelajaran menggunakan pendekatan rme; dan 3) siswa yang berkarakter demokratis baik tidak selalu mengarah pada kemampuan pemecahan masalah yang baik, namun siswa yang berkarakter demokratis rendah menyebabkan kemampuan pemecahan masalah siswa juga rendah. kata kunci: karakter demokratis, kemampuan pemecahan masalah, pendekatan realistic mathematics education (rme)

Students' democratic character and problem solving skills are still low and receive less attention in the application of mathematics. Students do not actively participate in discussion activities, tend to be silent and students still have difficulty in solving problems due to lack of confidence and lack of creativity. One of the efforts to develop democratic character and improve students' problem solving ability is the Realistic Mathematics Education (RME) approach. This study aims to 1) analyze students' democratic character during the learning process through RME; 2) find out the improvement of students' problem solving ability after participating in learning through the RME approach; and 3) analyze problem solving ability in terms of students' democratic character. This type of research is descriptive quantitative research with pre-experimenal design. The research sample was class VIII students totaling 45 students. The instruments used in this research are observation sheets of democratic character, initial test (pretest) and final test (post test) of problem solving ability. Data analysis of students' daily democratic character observations using the student democratic character assessment rubric. The results of the pretest-post test were analyzed by paired t-test and then the increase through N-Gain, and then the data on democratic character and problem solving ability were categorized. The results showed that 1) the development of students' democratic character during the learning process with the RME approach had increased; 2) there was an increase in students' problem solving ability after participating in learning using the RME approach; and 3) students with good democratic character did not always lead to good problem solving ability, but students with low democratic character caused students' problem solving ability to be low.
