This study aims to analyze students' numeracy literacy in solving proportional comparison problems. The research employs a qualitative method with a case study approach. The subjects of the study are 30 eighth-grade students from a public junior high school in Tasikmalaya. The instruments used include numeracy literacy tests, in-depth interviews, and classroom observations. The results indicate that the level of understanding of proportional comparison concepts varies widely among students. Students with a good understanding tend to use analytical and systematic strategies in problem-solving, while those with lower understanding rely on a trial-and-error approach. The main difficulties faced by students include understanding the language of problems, performing mathematical operations, and using visual representations. This study emphasizes the importance of developing conceptual understanding, effective problem-solving strategies, as well as improving mathematical literacy skills and the use of visual representations in teaching. The implications of these findings are the need for curriculum development and more effective teaching strategies to enhance students' numeracy literacy.
Penelitian ini bertujuan untuk menganalisis kemampuan literasi numerasi siswa dalam menyelesaikan masalah perbandingan senilai. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Subjek penelitian adalah 30 siswa kelas VII di Sekolah Menengah Pertama Negeri di Tasikmalaya. Instrumen yang digunakan meliputi tes soal literasi numerasi, wawancara mendalam, observasi kelas, dan analisis dokumen. Hasil penelitian menunjukkan bahwa tingkat pemahaman konsep perbandingan senilai sangat bervariasi di antara siswa. Siswa dengan pemahaman baik cenderung menggunakan strategi analitis dan sistematis dalam menyelesaikan masalah, sementara siswa dengan pemahaman rendah mengandalkan pendekatan trial-and-error. Kesulitan utama yang dihadapi siswa mencakup pemahaman bahasa masalah, operasi matematika, dan penggunaan representasi visual. Penelitian ini menekankan pentingnya pengembangan pemahaman konseptual, strategi pemecahan masalah yang efektif, serta peningkatan keterampilan literasi matematika dan penggunaan representasi visual dalam pengajaran. Implikasi dari temuan ini adalah perlunya pengembangan kurikulum dan strategi pengajaran yang lebih efektif untuk meningkatkan literasi numerasi siswa.
