2024-10-26T17:08:56+07:00

The Teaching Factory is one of the suitable learning models for vocational high schools. It combines student competence with production, where learning at school is conducted as it would be in an industrial/work environment by running service activities or production activities. SMKN 2 Salatiga is one of the schools that have implemented the teaching factory learning model, especially in the Construction and Housing Engineering expertise program, which includes making rosters, often accompanied by practical paving block production. This research aims to determine the influence of the teaching factory on competence through the creativity of 11th-grade students in the Construction and Housing Engineering program at SMKN 2 Salatiga. This study uses a quantitative approach with path analysis techniques. The conclusions of this study are: (1) Partially, the teaching factory positively affects the increase in student competence and creativity. (2) Creativity has a negative influence on the increase in student competence, and (3) The teaching factory learning model positively affects the increase in student competence through creativity as an intervening variable, although creativity cannot fully function as a connecting variable.

Effect of Used Tire Rubber Powder Addition as Eco-concrete Innovation Through Job Mix Formula on Compressive Strength and Modulus Elasticity of Concrete

2024-10-26T17:36:30+07:00

This article discusses the effect of adding used tire rubber powder as an admixture of fine aggregate using the design method of job mix formula K-250 according to SNI 03-2834-2000. The variation of adding used tire rubber powder is 0%, 2.5%, 5%, 7.5%, and 10% against the acceptable aggregate content weight ratio. The Fas used was 0.58 with 210 l/m³ water. The test methods used are inspection of concrete constituent materials, vicat test, slump test, compressive strength, and modulus of elasticity of concrete. From testing the slump test, compressive strength, and elastic modulus of 28-day-old concrete, the more the level of addition of used tire rubber powder, the value of slump, compressive strength, and modulus of elasticity of concrete decreases. Seen at an average compressive strength of 21.06 MPa has an elastic modulus value of 21564.02 MPa, while at an average compressive strength of 15.13 MPa, the average elastic modulus value is 18268.14 MPa. Both data show that regular concrete is plastic and concrete with an admixture of used tire rubber powder is elastic. The compressive strength value decreased proportionally to the used tire rubber powder addition level, with a percentage decrease of 28% from standard concrete. The theoretical modulus of elasticity decreased by 15% from regular concrete, and the experimental modulus of elasticity increased by 3%. From the stress-strain relationship graph, concrete with used tire rubber powder experienced an increase in strain value of 171% of regular concrete when subjected to a load of 140 kN. The strain value illustrates the elasticity of concrete, where the more significant the strain value in concrete, the more elastic the concrete. It is concluded that concrete with used tire rubber powder is elastic, and regular concrete is plastic. The elasticity of concrete affects the resistance of deformation when damage occurs, so concrete with used tire rubber powder can minimize structural damage because it is more elastic.

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

2024-10-26T17:54:07+07:00

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.
