Mathematical problem solving ability is surely the must-have any students in doinga math problem that is abstract. But many of the students who have not been able to use the problem-solving ability in doing a math problem. Many of them assumed that mathematics is a difficult lesson, and it usually requires a high concentration oflearning math. So the efficacy of self (self efficacy) is in need of students to cope with these problems. Self-efficacy (self efficacy) refers to the belief that relates to the ability and willingness of a student to achieve and complete tasks and results of the study with the target time has been determined and self efficacy refers to the consideration of how big someone's beliefs about their ability to perform a number of learning activities and their ability to complete tasks. Students who have a good self-efficacy will be successful in theirlearning activities andcanperform academic duties smoothly likewise viceversa if the efficacy in low students then have students will quickly give up on any problems in dealing with. Hence the need for self-efficacy so that arise from the student is either the later will provide confidence in the ability of students in solving mathematical problems.

One of the purpose mathematic learning is to develop problem solving abilities. Problem solving is obtained through experience in questioning non-routine. Improving students’ mathematical problem-solving abilities required an appropriate strategy in learning activities one of them is models problem based learning (PBL). Thus, the purpose of this research is to determine whether the problem solving abilities of mathematical students’ who learn to use PBL better than on the ability of students’ mathematical problem solving by applying conventional learning. This research included quasi experiment with static group design and population is students class XI MIA SMAN 1 Lubuk Alung. Class experiment in the class XI MIA 5 and class control in the class XI MIA 6. The instrument of final test students’ mathematical problem solving used essay form. The result of data final test in analyzed with t- test. The result is students’ mathematical problem solving abilities with PBL better then on the ability of students’ mathematical problem solving by applying conventional learning. It’s seen from the high percentage achieved by the group of students who learn to use PBL for each indicator of students’ mathematical problem solving.

Students' mathematical problem solving ability is one thing that must be considered. This is because when students are given problem solving problems in the form of routine students are able to solve these problems, but if a non-routine problem arises, students will have difficulty. During teaching and learning activities students are able to solve problems when presented with questions of the same type. However, if given a variety of questions, some students have difficulty working on them. This study aims to explore and describe students' mathematical problem solving abilities in solving spatial problems. This study uses a descriptive qualitative approach. The data analysis technique in this study used descriptive analysis techniques. The results of the analysis show that high-ability subjects can understand the problem by writing steps, solving problems, re-examining the results of work very precisely and correctly. Students with moderate abilities can only solve problems without writing what is known and asked. Meanwhile, low-ability students cannot fulfill all aspects of mathematical problem solving.
