This study aims to obtain an overview of the learning obstacles experienced by students in terms of mathematical literacy skills obtained through the experience of students in solving problems on flat-sided space building material space and shape content. The research method used is the qualitative method. This research involved students of grade VIII of SMPN 2 Sungguminasa and a subject teacher. The analysis of students' mathematical literacy skills and learning obstacles was carried out based on the results of the test instrument of the mathematical literacy competency test on space and shape content, in-depth interviews, and direct observation. The results show that students experience learning obstacles that are ontogenic, didactic, and epistemological in solving flat-sided space problems based on students' mathematical literacy skills. The ontogenic learning obstacle is the lack of basic geometry skills which results in errors in the application of flat-sided space formulas, determining the position of lines. Didactic learning obstacles are incomplete understanding of the concepts obtained where students tend to only use quick formulas so they forget to use the right and easy problem-solving procedures. The epistemological learning obstacle is the lack of understanding of the concept of students who tend to memorize formulas so that when developing problems students cannot solve the given mathematical problems. Based on this, this study obtained an overview of the didactical situation based on the learning obstacles experienced by students based on mathematical literacy skills.
