Abstract
Tujuan penelitian ini adalah untuk menganalisis kesalahan siswa SMP dalam menyelesaikan soal cerita sistem persamaan linear dua variabel berdasarkan kemampuan tingkat tinggi, tingkat sedang dan tingkat rendah yang dimiliki siswa. Penelitian ini dilakukan pada siswa kelas VIII G SMP Negeri 1 Wungu, kemudian untuk menentukan subjeknya dilihat dari nilai hasil Ujian Tengah Semester (UTS) yang diperoleh dari guru matematika. Peneliti menggunakan 6 siswa untuk digunakan sebagai subjek.Teknik pengumpulan data dilakukan dengan metode tes, wawancara, dan dokumentasi. Teknik keabsahan data dilakukan dengan triangulasi waktu yaitu membandingkan data hasil tes dan wawancara tahap 1 dengan data hasil tes dan wawancara tahap 2. Pada penelitian ini analisis data menggunakan 3 tahap yaitu reduksi data, data display dan verivikasi/penarikan kesimpulan. Kesimpulan dari hasil penelitian ini adalah: 1) subjek berkemampuan tinggi tidak melakukan kesalahan dalam menyelesaikan soal. 2) subjek berkemampuan sedang memiliki tingkat kesalahan sedang, subjek tidak menuliskan kesimpulan dari soal yang telah dikerjakan. 3) subjek berkemampuan rendah memiliki tingkat kesalahan tinggi, subjek tidak dapat mentransformasikan soal, subjek tidak mengetahui prosedur yang dibutuhkan untuk menyelesaikan soal tersebut dan subjek tidak dapat menuliskan kesimpulan dari soal yang telah dikerjakan. Dari kesalahan-kesalahan yang dilakukan siswa, penelitian selanjutnya diharapkan dapat mengembangkan Lembar Kerja Siswa atau media pembelajaran yang menarik agar siswa paham dengan materi yang diajarkan untuk meminimalisir kesalahan yang dilakukan siswa.
