This study aims to describe the ability to solve mathematical problems in terms of self-confidence in two-dimensional figure material. This research uses a descriptive qualitative research method. The subjects in this study were students of SMP Negeri 9 Serang City class VII selected by purposive sampling. The time of the research was carried out in the even semester of the 2020/2021 academic year. The instruments used in this study were self-confidence questionnaires, mathematical problem-solving ability tests, and interview guides. Data collection techniques in this study used the triangulation method through tests, questionnaires, and interviews. The analysis techniques used are data reduction, data display, and conclusion drawing/verification. The results of this study indicate that: (1) subjects with high self-confidence can solve three problems solving according to Polya namely, understand the problem, devise a plan, and carry out the plan, (2) subjects with average self-confidence can solve two problems solving according to Polya namely, understand the problem and devise a plan, and (3) subjects with low self-confidence only able to fulfill the stages of problem solving according to Polya namely, understand the problem.References
