%X Kemampuan representasi matematis merupakan aspek penting dalam pembelajaran matematika karena membantu siswa memahami, mengorganisasi, dan mengomunikasikan ide-ide matematika secara efektif. Penelitian ini bertujuan mendeskripsikan kemampuan representasi matematis siswa SMP pada materi operasi hitung bentuk aljabar ditinjau dari self-efficacy. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus. Subjek penelitian adalah siswa kelas VII di salah satu SMP di Kota Cimahi yang telah mempelajari materi operasi hitung bentuk aljabar. Teknik pengumpulan data melalui angket self-efficacy, tes kemampuan representasi matematis, dan wawancara terhadap tujuh siswa terpilih yang mewakili setiap tingkatan self-efficacy. Hasil penelitian menunjukkan bahwa sebagian besar siswa memiliki kemampuan representasi matematis pada kategori kurang. Siswa dengan self-efficacy tinggi cenderung memiliki kemampuan representasi matematis kategori baik. Siswa dengan self-efficacy sedang memiliki kemampuan representasi matematis yang beragam, dengan siswa cenderung berada pada kategori cukup dan kurang. Siswa dengan self-efficacy rendah cenderung memiliki kemampuan representasi matematis kategori kurang. Siswa dengan self-efficacy tinggi tidak mengalami kesulitan dalam menyelesaikan soal, namun masih terdapat sedikit kesalahan karena kurang teliti. Siswa dengan self-efficacy sedang masih mengalami kesulitan dalam merencanakan strategi penyelesaian soal dan cenderung tidak melakukan evaluasi terhadap hasil pekerjaannya. Siswa dengan self-efficacy rendah mengalami kesulitan dalam menyelesaikan soal karena kurang memahami materi operasi hitung bentuk aljabar.    Mathematical representation ability is an important aspect of mathematics learning as it helps students understand, organize, and communicate mathematical ideas effectively. This study aimed to describe the mathematical representation ability of junior high school students on algebraic operations, as viewed from their self-efficacy. This research used a qualitative approach with a case study method. The subjects were seventh-grade students at a junior high school in Cimahi City who had studied algebraic operations. Data were collected through a self-efficacy questionnaire, a mathematical representation ability test, and interviews with seven selected students representing each level of self-efficacy. The results of the study showed that most students had mathematical representation abilities in the low category. Students with high self-efficacy tended to have mathematical representation abilities in the good category. Students with moderate self-efficacy demonstrated varied mathematical representation abilities, with a tendency to fall into the fair and low categories. Meanwhile, students with low self-efficacy tended to have mathematical representation abilities in the low category. Students with high self-efficacy did not encounter significant difficulties in solving problems, although minor errors still occurred due to inaccuracy. Students with moderate self-efficacy experienced difficulties in planning problem-solving strategies and tended not to evaluate the results of their work. Meanwhile, students with low self-efficacy experienced difficulties in solving problems due to a limited understanding of algebraic operations.
