The method used in this study is classroom action research (CAR). Research takes the form of cycles that last twice the cycle, depending on the success rate of the target achieved. The research subject in this study was a student of class XI Design Modeling and Building Information (DPIB) Vocational High School (SMK) Negeri 5 Sungaipenuh. The number of students in this class is 14 students. Data analysis techniques are carried out by assessing the activeness of students' learning and assessment of learning outcomes. Student learning outcomes in the first cycle with a total of 14 students, with an average score of 72.86, and students who achieved the completion of 8 people's learning, which is 57.14%. In the second cycle with the number of students was 14 people, with an average score of 79.29, and students who achieved the completion of learning 11 people, namely 78.57%. In this second cycle, the average grade of students has reached above the Minimum Completion Criteria (MCC). Keywords: Learning Outcomes, Cooperative Learning, STAD, CAR INTRODUCTION Based on observations conducted in the July-December 2020 semester in class XI DPIB SMK Negeri 5 Sungaipenuh, there is a problem faced by the school that is seen students are less active in the learning process in the subjects of Construction Cost Estimation. One of the causes is that during the learning process, it is still centered on teachers and less interactively involved in the learning process so that it makes students feel saturated and less able to develop optimal learning skills. Teachers dominate the learning process as if there is only one-way communication between students and teachers. In addition to this, another problem encountered is the lack of adequate learning ools, resource books, and other learning media, so that the learning process becomes more passive for students and the role of teachers is very dominant. With these limitations, it is increasingly difficult to achieve the Minimum Completion Criteria required, especially for the subjects of Construction Cost Estimation in SMK Negeri 5 Sungaipenuh. Based on the problems that have been outlined above, as well as the results of observations of the teaching and learning process in SMK Negeri 5 Sungaipenuh. Making the learning results obtained by students to be low and less satisfactory, this is indicated by the acquisition of the average grade of the Final School Examination (UAS) as in the following table: Table 1.
