The goal of this research is to describe the analysis of mathematics students error to solve problem of linear programs. This research belongs to the type of qualitative research with using a descriptive approach. The data collection technique is done by giving tests in the form of linear program story questions and interviews. This study used in fifth semester of the students of mathematics of Pahlawan University. The results showed that the types of conceptual errors are: a) making graphic error solution, b) error in using the concept of a variable that will be used, c) identify what is asked and d) choosing error symbol. Procedural errors are: a) error in choosing the strategy to be used in problem solving, b) error in apply strategy to solve the problem, and c) error in viewing return what is the solution obtained is in accordance with what known and asked. Causative factor students make mistakes in solving program problems linear: a) Students are not accustomed to solving story problems so that students have difficulty transform into a mathematical model b) Students do not understand the concept of symbols inequalities c) Students are less proficient at making graphs including determining the area completion d) Students do not understand the concept of extreme points e) Students are less thorough in performing calculation operations

Learning tools become one of the important things in the learning process that has an impact on the ability of students, especially the ability to think creatively. Learning tools in the form of RPP and LKPD can create an effective and fun learning process, and can facilitate students' creative thinking skills. Although this creative thinking ability is one of the important abilities and must be mastered by students, there are still many students who find it difficult to solve problems that can encourage the development of students' creative thinking skills, so it is necessary to develop learning tools that can help improve students' abilities. creative thinking of students. Learning according to these characteristics is the STEM integrated Project Based Learning model of mathematics learning. This study aims to design valid, practical and effective learning tools in the form of STEM-PjBL-based RPP and LKPD for Class VIII Junior High School students. The development research was carried out using the Plomp development model. The Plomp development model consists of three stages, namely the preliminary research stage, the development or prototyping stage and the assessment stage. Data were collected through questionnaires, interviews and observation sheets. Analysis of the validity data showed that the resulting device was in the very valid category with a RPP validity score of 3.63 and LKPD 3.54. In the analysis of practicality data, it was found that the mathematics learning tools were practical with a practicality score of 82.1% for RPP and LKPD 82%. Learning tools are effective based on learning outcomes where the completeness is 63.02 %. Based on the results of the study, it was concluded that the STEM-PjBL-based learning tools developed were valid, practical and effective.
