Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematis siswa SMP dalam menyelesaikan masalah matematis pada materi bangun ruang sisi datar ditinjau dari tingkat self-efficacy. Fokus utama dari penelitian ini adalah tiga bentuk representasi matematis, yaiturepresentasi visual, verbal, dan simbolik. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus. Subjek penelitian terdiri dari 6 siswa kelas IX di salah satu SMP Negeri di Kota Bandung yang dipilih berdasarkan kategori tingkat self-efficacy tinggi, sedang, dan rendah. Instrumen yang digunakan meliputi angket semantik diferensial selfefficacy, tes representasi matematis, dan wawancara. Hasil penelitian menunjukkan bahwa siswa dengan self-efficacy tinggi mampu memenuhi seluruh indikator representasi matematis pada materi bangun ruang sisi datar dengan baik, baik dalam aspek visual, verbal, maupun simbolik. Siswa dengan self-efficacy sedang cenderung mencapai ketiga indikator representasi matematis pada materi bangun ruang sisi datar, namun terdapat kekeliruan dalam pengerjaannya. Siswa dengan self-efficacy rendah hanya menunjukkan pencapaian pada representasi simbolik pada materi bangun ruang sisi datar, meskipun banyak terjadi kesalahan dalam perhitungan dan proses penyelesaian masalah. Temuan ini mengindikasikan bahwa tingkat self-efficacy siswa berperan penting terhadap kemampuan representasi matematis siswa dalam menyelesaikan masalah matematis pada materi bangun ruang sisi datar. This study aims to describe the mathematical representation ability of junior high school students in solving mathematical problems on the polyhedron, viewed from the level of self-efficacy. The main focus of this research is on three forms of mathematical representation: visual, verbal, and symbolic. The study employs a qualitative approach using a case study method. The research subjects consisted of six ninth-grade students from a public junior high school in Bandung, selected based on high, medium, and low levels of self-efficacy. The instruments used include a semantic differential self-efficacy questionnaire, a mathematical representation test, and interviews. The results showed that students with high self-efficacy were able to meet all indicators of mathematical representation on the topic of three dimensional shapes with flat surfaces well, including the visual, verbal, and symbolic aspects. Students with medium self-efficacy tended to achieve all three indicators of mathematical representation, although some errors were found in their work. Students with low self-efficacy only demonstrated achievement in the symbolic representation on the topic, although there were many errors in calculations and problem-solving processes. These findings indicate that students’ self-efficacy levels play a significant role in their mathematical representation ability on the topic polyhedron.
