Mathematics Modeling Ability of Students in Class XI Linear Program Materials with Problem based Learning Model

Mathematical modeling ability is a significant aspect of learning mathematics. Real problems can be solved through a mathematical process with modeling. The background of the problem in this study was the low mathematical modeling ability of students, especially in the Linear Programming materials. The application of the PBL model can be used as a problem solution for these matters. The purpose of this study is to obtain an overview of the modeling ability of students' mathematics on linear programming material after applying the PBL model. The research was held at SMA YPI Tunas Bangsa Palembang with 37 students as research subjects. The method used in this research is descriptive with data analysis techniques carried out quantitatively and qualitatively based on mathematical modeling indicators. The data was obtained from the test results in the form of essay questions and results of interviews with students. Based on the results of the data analysis, it can be concluded that the ability of mathematical modeling students on linear programming material after the PBL model was applied is in a medium category with a percentage of 46.24%. Therefore, the PBL model can be used as an alternative for teachers in improving students' mathematical modeling skills.
