Abstract


Tujuan dari penelitian ini adalah untuk mengungkap strategi dan tingkat ekspresi kepekaan bilangan siswa sekolah dasar dalam menyelesaikan masalah terkait dengan operasi bilangan bulat, yang meliputi operasi penjumlahan, pengurangan, dan perkalian. Kajian ini menggunakan pendekatan kualitatif. Responden dalam penelitian ini terdiri atas 5 orang siswa yang diambil secara acak dari sebuah Sekolah Dasar di Pulau Lombok. Data dikumpulkan melalui tes. Analisis data menggunakan tiga indikator kepekaan bilangan untuk menjawab dua pertanyaan penelitian. Hasil penelitian ini menunjukkan bahwa: Pertama, strategi yang digunakan siswa dalam menyelesaikan masalah terkait operasi penjumlahan, pengurangan, dan perkalian bilangan bulat adalah seragam dan terpaku pada penggunaan algoritma atau prosedur berhitung yang bersifat baku dan rutin, yaitu prosedur penjumlahan bersusun, pengurangan bersusun, dan perkalian bersusun. Kedua, berdasarkan empat tingkatan ekspresi kepekaan bilangan, yaitu belum nampak, nampak, terungkap, dan terampil, temuan penelitian ini menunjukkan bahwa tingkat kepekaan bilangan siswa termasuk dalam katagori belum nampak, yaitu level terendah dari 4 tingkatan tersebut.
