The observation sheets is analyzed in qualitative desciptive, while the students mathematic tests is analyzed in quantitative descriptive. The qualitative descriptive show an improvement of learning process prior to the action on the first and second cycle. Most of students are very confidence and active in learning process, such as while they are finishing mathemathic’s problems that given, presenting the result of problems and giving the conclusion of learning. The results of this study indicate the number of students who reached Minimum Mastery Criteria of knowledge increase from basic score to first test and second test. The results of this research showed an increasing number of students learning mathematics about knowledge of the basic score (28,13%) to the first test (59,37%) to the second test (71,89%). For the skills of the first test (65,62%) to the second test (87,50%). From these data it can be concluded that the application of Problem Based Learning can increase mathematics achievement from the students at class VIIJ SMP Negeri 1 Siak Hulu in academic years 2018/2019 for the subject Aritmatika Soaial.
