Teachers cannot reach all the students in the class. This results in a significant difference in value between the most intelligent and least intelligent students on elements of Cost Planning and Building Construction Scheduling. This difference in scores is a factor in selecting peer teaching learning methods. This research was conducted to determine how effective peer teaching to improving student learning results in elements of Cost Planning and Building Construction Scheduling. The type of research used is experimental research with a non-equivalent pretest posttest control group design model. The number of samples used was 36 people: 18 students of class XI DPIB 1 who acted for the control class and 18 students of class XI DPIB 2 who acted for the experimental class. The experimental class uses a peer tutor teaching approach. The research was conducted by providing test instruments in the form of a pretest and posttest which were first tested on 26 class XI students of SMK Negeri 1 West Sumatra. The average of student learning results in the experimental class was 92.17 and the control class was 47.89. Student learning results appear to be better than the average comparison of the two classes in this study. Hypothesis testing used the Mann Whitney U-Test which found that Asymp.Sig < 0.05 and 0.000 < 0.05. So, from hypothesis testing it is stated that peer teaching is effective in improving student learning results in the Elements of Cost Planning and Building Construction Scheduling.

Vocational High Schools face several issues related to the facilities and infrastructure of the practical room for the Building Modeling and Information Design Expertise Program (DPIB), such as a lack of adequate drawing tables and uncomfortable, hot room conditions, which reduce student comfort. Additionally, supporting equipment such as cleaning tools and safety equipment (K3) are insufficient, and the maintenance of facilities is not carried out optimally. These conditions hinder the effectiveness of the learning process and do not meet the national standards set by Permendikbud Number 34 of 2018.This study aims to evaluate the adequacy of facilities and infrastructure in the practical room of the Building Modeling and Information Design Expertise Program (DPIB) at SMK Negeri 1 Lintau Buo, based on the standards outlined in Permendikbud Number 34 of 2018. The evaluation focuses on equipment completeness, the physical condition of the practice room, and other supporting facilities used for learning activities. The research employs an evaluative method with a quantitative descriptive approach. Data were collected through direct observation, interviews with school officials, and documentation of the existing facilities.The results indicate deficiencies in the quality of the drawing tables and the uncomfortable condition of the practice room, both of which could potentially hinder the achievement of national education standards. This research is expected to provide valuable input for the school to improve its facilities and infrastructure to support more effective and efficient learning activities in the future.
