The purpose of this research was to determine the percentage of student errors in solving story problems on the linear program material. The errors noted were misunderstandings of questions, errors in mathematical modeling, errors in calculating / solving, and errors in drawing conclusions. The research was conducted on class XI MIPA students of SMA Negeri 1 Langowan. The results showed that all students made mistakes solving story problems with the material of the linear program. There were 38 errors (23.89%) at the question understanding stage. There were 5 errors (3.14%) at the mathematical modeling stage. There are 90 errors (56.60%) at the computation / completion stage. There were 24 errors (15.09%) at the conclusion stage. There were 2 other errors (1.25%) made by students. © Published under licence by IOP Publishing Ltd.
