This research is motivated by the low ability of students to solve mathematical problems, especially in the matter of two-variable linear equation systems. The reason is that students are not used to solving problems using problem solving skills. Efforts that can be made to improve mathematical problem solving skills are to design learning activities to make students accustomed to solving given contextual questions by applying problem solving steps. One learning model that can help students improve their mathematical problem solving abilities is the Problem Based Learning (PBL) model. In addition to the use of models in the implementation of learning, the use of learning approaches is also very much needed so that learning is carried out properly. One of the learning approaches designed to support students in solving mathematical problems is a scientific approach.
The teacher must have a systematic preparation and implementation of learning. However, some learning tools are not in accordance with the process standards in Permendikbud No 22 of 2016, such as the steps in the lesson plan are not clear and the LKPD is in the form of a summary of the material. So the purpose of this research is to produce a product in the form of learning tools (Syllabus, RPP and LKPD) on the material system of two-variable linear equations using a PBL model that is valid, practical and effective in order to improve students' mathematical problem solving abilities.
This type of research is development research with the development model used is 4D. namely define, design, develop and disseminate. In the define stage, the things that are done are the initial-end analysis, student analysis, material analysis, task analysis and formulation of learning objectives. In the final initial analysis, the results obtained were that the applicable curriculum was the 2013 curriculum, the problems encountered were the low ability of students to solve mathematical problems and the constraints of learning devices.
The results of the material analysis obtained that there were 5 materials compiled, namely completing the PLDV, completing the SPLDV using the graphical method, completing the SPLDV with the substitution method, completing the SPLDV with the elimination method and completing the SPLDV with the mixed method. The results of the material analysis are used to determine the tasks that will be carried out by students during learning. The define stage ends with the formulation of learning objectives. Learning objectives are determined based on the results of material analysis and task analysis.

The researcher did the design stage by compiling a test instrument that was used to assess the validity, practicality, and effectiveness of the learning device. make a design learning device that will be developed. in this case selecting the format and designing the initial design according to the format taken. The develop stage includes the development of learning tools according to the initial design, product validation, product revision, and product trials.
Based on the results of validity data analysis, the validity of the syllabus learning device is 95.33% with a very valid category, the validity of the lesson plan is 92.72% with a very valid category and the validity of the worksheet is 91.85% with a very valid category. The validity of the ability to solve mathematical problems is 95.13% with a very valid category. The test results of the mathematical problem-solving ability test show that the correlation coefficient of the validity of item number 1 and 2 has a very good interpretation. High test reliability correlation coefficient with good interpretation quality. The results of the discriminating index test were obtained for item number 1 of 0.524 (moderate), item number 2 of 0.571 (moderate). The test results of the difficulty level of the items obtained for both test items are at a moderate level of difficulty and can be used as research instruments.
The results of the practicality of the LKPD in the limited trial were 87.48% in the very practical category. The practical results of LKPD in field trials were 86.16% for student response results, teacher observations with an average of 92.68%. Thus, it can be concluded that the learning tools developed are very practical.
Based on the test results of data analysis of mathematical problem solving abilities, it was obtained that the average mathematical problem solving ability of students who used problem-based mathematics learning tools in the experimental class was higher than students who did not use problem-based mathematics learning tools. The results of the N-Gain test showed that students who used problem-based mathematics learning tools had higher mathematical problem solving abilities than students who did not use problem-based mathematics learning tools.
Because the average posttest score of the experimental class was higher than the average posttest score of the control class, and the increase in the mathematical problem solving abilities of the experimental class students was higher than the increase in the problem solving abilities of the control class, it can be concluded that problem-based mathematics learning tools proved effective. The disseminate stage is carried out by making articles to be published, and distributing learning tools to schools that have contributed to this research.
Keywords: Mathematical Learning Tools, Problem Based Learning Models, Mathematical Problem Solving Ability, Linear Equation System of Two Variables.
