The purpose of this study was to describe the understanding of Class VIIIC students of SMP IT Qurrota A'yun Palu in solving the story problems of the Two Variable Linear Equation System. The research using a qualitative descriptive approach. The result of this study is that the understanding of students with high abilities shows that students tend to have a good understanding, both from understanding translation, understanding interpretation, and understanding extrapolation. The understanding of students with moderate ability shows that students have a good understanding of understanding translation and interpretation, but lacking in understanding extrapolation. Moderately capable students are able to convey and understand story problems, interpret and describe the intent of the questions, and determine the concept or appropriate steps properly and correctly. However, it is inaccurate and there are errors in applying the concept of mathematical calculations and concluding answers. The understanding of low-ability students has a fairly good understanding, on translational understanding, low-ability students can convey and understand story problems, but are unable to interpret and describe the intent of the questions, determine concepts or steps for solving problems and are unable to apply the concept of calculation and conclude the answer completely, which means that low-ability students are very lacking in understanding interpretation and extrapolation.

The purpose of this study is to profile the mathematical connection ability of students who have high mathematical abilities in the sub-topic of trigonometric equations. The research design uses a qualitative approach. The study was conducted on students of St. Andreas Palu Catholic High School. The instruments used are written assignments and interview guidelines. The results of this study show that the connection ability of students with high mathematical ability in solving equation problems in each category includes: 1) In the modeling connection category, students know the information in the problem completely and precisely this is characterized by recognize the relationship between time and trigonometry so that students can use the formulas they know to determine when the right time is so that the ship can enter the port based on known equations. 2) In the concept connection category, students understand the concept of trigonometric equations and trigonometric comparisons in solving trigonometric equation problems. However, the subject did not understand well the interrelationship of the concept of cosine trigonometric equations with the given question so that an incorrect final answer was obtained. 3) In the category of procedure connections, students relate concepts through appropriate procedures so that they can solve trigonometric equation problems.
