This research is started from the low of students problem solving emphasizing on mathematical representation of student which problems root because of model used by the teacher is less relevant. This research is conducted to know, (1) how the comprehension and improvement of students problem solving emphasizing on mathematical representation through problem based learning (PBL), (2) How complete learn of students problem solving emphasizing on mathematical representation through problem based learning (PBL) at discussion at system of linear equation two variable. This research is a classroom action research. The subject of this research is 30 students of grade VIII A SMP Angkasa LANUD Medan. The research object is the improvement of students problem solving emphasizing on mathematical representation. Result of data analysis at cycle one is: (1) score mean of students problem solving emphasizing on mathematical representation is 55,43, (2) student’s problem solving emphasizing on mathematical representation is 19 (63,33%) students. (3) The mean score of teacher’s observation is 82,27 % with good category. (4) The mean score of students observation is 79,00% with unfavourable category. The result of data analysis at second cycle is (1) score mean of student’s problem solving emphasizing on mathematical representation is 72,65, (2) student’s problem solving emphasizing on mathematical representation is 27 (90%) students. (3) The mean score of teacher’s observation is 94,37% % with very good category. (4) The mean score of students observation is 92,00 % with very good category. . From the result of research, It is concluded that the application of problem based learning can improve of student’s problem solving emphasizing on mathematical representation. and the study process which is conducted is good. Based on this conclusion it is expected that this research finding can be used as reference to improve the student’s problem solving emphasizing on mathematical representation.
