Learning Outcomes of Class XI Students of Building Construction and Sanitation Expertise Concentration on Building Construction Cost Estimation Elements at SMK N 7 Semarang with the Application of Skill Based Learning Model Assisted by Google Classroom Me

Abstract

The background of this study began during the implementation of UNNES Lantip 3 at SMK N 7 Semarang on August 31 - November 9, 2024. The researcher taught 11th grade Building Construction, Sanitation, and Maintenance major with the subject of Construction Cost Estimation. Furthermore, the researcher explored this lesson for further research. Based on pre-research data and interviews on October 30-31, 2023, KGSP grade XI students had difficulty in understanding Construction Cost Estimation, especially the calculation of volume and material requirements and work wages. Therefore, it is necessary to apply learning models and supporting media that are in accordance with the characteristics of construction cost estimation subjects, which are close to the characteristics of the skill-based learning model and Google Classroom. The purpose of this study was to determine the learning outcomes of grade XI students in the concentration of building construction and sanitation expertise in the element of building construction cost estimation at SMK N 7 Semarang after the application of the skill-based learning model assisted by google classroom media. This type of research is quantitative research with a Quasi Experimental Design approach. The samples used in this study were class 11 KGSP 1 as a control class totaling 32 students using a conventional learning model and 11 KGSP 2 as an experimental class totaling 33 students using a skill-based learning model assisted by google classroom media. The data collection technique is with a question instrument in the form of an initial test (Pre-Test) and a final test (post-test). The validation test is using the Product Moment formula, while the data reliability test is using the Alfa Cronbach technique. Data analysis techniques used by using t-test or average difference test. The results of this study indicate that the average post-test value (74.24) is higher than the pre-test value (39.39) in the experimental class, while the control class post-test value of (45.16) is much lower than the experimental class. This is evidenced by the Paired Sample t-test hypothesis test with a significance value (2-tailed) of (0.00 <0.05), which indicates a significant difference. In addition, the Independent Sample t-test hypothesis test with a significance value (2-tailed) of (0.00 < 0.05) also showed a significant difference. From these results, it can be concluded that the application of the Skill Based Learning model assisted by Google Classroom media improves student learning outcomes and is better than the conventional learning model on building construction cost estimation elements of class XI Phase F Building Construction and Sanitation Concentration at SMK N 7 Semarang.
