Abstract
Conceptual understanding is an understanding of theories, facts, rules, descriptions, and terminology of mathematics as well as all relevant information while procedural understanding is the procedure or set of rules (mathematical formula) to calculate or solve problems. Linear programming is a mathematical content very closely with procedural. The purpose of this study was to analyze the conceptual understanding and procedural understanding mathematics education students in the program linear material which familiar with the procedural. This research was conducted at a university by descriptive quantitative research methods using the test as an instrument for analyzing the two students ability in the form of a percentage. The results showed that 1) only 16% of students can understand correctly the concept of social arithmetic on linear programming problem is given. 2) Only 2% were able to formulate a mathematical model for the relationship between variables correctly and be able to relate to the concept of a linear program as the constraints. 3) Procedural ability on the simplex method is still less than 50%
