Abstract
Student competency in solving non-routine problem is very important. In the other hand, some students have obstacles in solving the problem, especially in the topic of system of linear equation in two variables (SLTEV). This purpose of this research is to identify learning obstacle by students in solving non-routine problems of SLTEV. The subjects of this study were five students of 8th grade in a Junior High School in Jakarta. The method of this research was qualitative with case study research design. The data was collected by using test of non-routine problems test and interview guideline. The non-routine problem of SLETV test consists of three questions. The interview was conducted by asking related questions about solving the problems. This research was not held in offline situation because of pandemic, so the ontogeny obstacle could not be observed. The data was analyzed in depth to identify the learning obstacle. The research results are there two learning obstacles, which are epistemological and didactical obstacles. The epistemological obstacle that found is students get confused in formulating or transcribing non-routine problems. The didactical obstacle that found is the sources of learning in the school just have few examples of non-routine problems.
