Abstract: Belajar materi peluang membutuhkan kombinasi logika berpikir dan pengalaman dalam kehidupan sehari-hari. Penelitian deskriptif kualitatif ini bertujuan mendeskripsikan cara berpikir siswa berdasarkan hasil analisis pemahaman konsep peluang siswa SMP yang ditinjau dari urutan aksi, proses, objek, dan skema. Subjek terdiri dari 3 siswa kelas IX SMP yang diambil secara purposive dan memiliki kemampuan yang berbeda-beda masingmasing tinggi, sedang, dan rendah. Instrumen penelitian utama adalah peneliti dibantu instrumen pendukung berupa 2 soal pada tes kemampuan matematika dan pedoman wawancara. Hasil penelitian menunjukkan aksi dari ketiga subjek yaitu mengetahui tindakan awal untuk menyelesaikan soal peluang dan mampu menjelaskannya secara verbal maksud dari soal tes yang diberikan. Subjek berkemampuan matematika tinggi dan sedang menjelaskan secara terperinci sedangkan subjek berkemampuan matematika rendah menjelaskan secara sederhana. Subjek berkemampuan matematika tinggi dan sedang mencapai tahap proses, subjek berkemampuan matematika tinggi menggunakan tabel dalam penyelesaiannya. Pada tahap objek subjek berkemampuan matematika tinggi dan sedang menyelesaikan soal tes dengan caranya masing-masing yaitu subjek berkemampuan matematika tinggi menyelesaikan soal dengan metode yang dipahaminya dan subjek berkemampuan matematika sedang menyelesaikan dengan menyederhanakannya. Skema yang dimiliki subjek berkemampuan tinggi dan sedang yaitu mampu mengembangkan konsep yang telah mereka pelajari.
The study of probability needs a combination of logical thinking and experience in daily life. The purpose of this qualitative descriptive research is to describe the way of students thinking based on the analysis results toward the understanding of the probability concept of junior high school students based on stages of APOS (action, process, object, and scheme). The subjects of this research are three junior high school students grade IX by using purposive technique with different mathematics ability: high, medium, low. The main instrument of research is the researcher and two questions of mathematics ability test questions and interview guidelines as the supporting instruments. The results of the research showed that the action of the three subjects knew the first action to solve the probability questions and were able to explain verbally about the meaning of questions test. The high and medium capable subjects explained it as detail as possible while the low capable subject explained it simply. The high and medium capable subject achieved the process stage and the high capable subject used a table to complete the test. On the object stage, the high and medium capable subjects answered the questions based on their own way. The high capable subject solved the questions by using the methods that have been learnt and the medium capable subject preferred to simplify it. The high and medium capable subjects were able to develop the concept that has been learned on the scheme stage.
