Abstract

This study originated from the lack of enthusiasm of students following the learning of milling machining in the classroom, because of the many distractions that make it difficult for students to concentrate. The purpose of this study is to determine whether there is a difference in students' learning concentration in the subject of milling machining techniques of vocational high school students when they are taught with whiteboard animation media and textbooks. This research design is a quasi-experiment with post-test only. Based on the researcher's consideration and initial interviews, the subjects of this study were formulated as two classes. The number of students for the experimental class XI TPM 1 (15 people) and the conventional class XI TPM 2 (15 people). The experimental class XI TPM 1 was given whiteboard animation learning media, while the conventional class XI TPM 2 was given conventional learning. To analyze the research data, t-test technique was used. The results of the t-test analysis showed that, compared to the conventional learning method, students learned milling machining techniques with higher concentration.

Abstract

Additive Manufacturing (AM), particularly Fused Deposition Modeling (FDM), has evolved from a rapid prototyping technology into a manufacturing approach for producing functional components across a wide range of industrial sectors. Nevertheless, the limited build volume of FDM systems has encouraged the use of adhesive bonding as a practical method for joining sub-components, with the single-lap joint (SLJ) configuration being among the most widely adopted designs. This review aims to provide an integrated analysis of the relationship between FDM-induced surface morphology, the adhesion mechanisms developed at the bonded interface, and their implications for stress distribution, shear strength, and joint failure modes. The findings indicate that the surface characteristics generated by the FDM process, including layer lines, stair-stepping effects, voids, and porosity, create interfacial conditions that differ fundamentally from those of homogeneous materials. These characteristics also produce a non-linear relationship between surface roughness and joint strength. Process parameters such as printing orientation and layer height were identified as key controlling factors that influence surface topography and adhesive performance. From a mechanical perspective, the eccentric load path inherent in SLJ configurations generates significant shear and peel stress concentrations at the overlap ends. These stress concentrations coincide with structurally weak regions that are intrinsically associated with FDM adherends, making them the primary sites for crack initiation and joint failure. Furthermore, modifications to overlap geometry and tailored adhesive distribution have been recognized as effective strategies for improving stress redistribution and enhancing the load-bearing capacity of the joint. This review highlights that the assessment of adhesive joints in FDM-manufactured components requires an integrated analytical framework that accounts for the coupled interactions among printing process parameters, surface conditions, adhesive properties, and progressive failure modeling. Such an approach is essential for the development of reliable structural joint designs for FDM-based applications.

Abstract

This study aimed to analyze the effect of the Video-Assisted Problem Based Instruction (PBI) learning model on students’ learning outcomes in Lathe Machining Engineering by controlling learning motivation variables. The study employed a quasi-experimental method using a Post-test Only Control Group Design. The research sample consisted of 50 students divided into an experimental class (25 students) and a control class (25 students) at SMKS Semen Padang. Data collection instruments included learning outcome tests and learning motivation questionnaires. Data were analyzed using Analysis of Covariance (ANCOVA). The findings demonstrated that the implementation of the video-assisted Problem Based Instruction learning model exerted a statistically significant effect on students’ learning outcomes, as indicated by the ANCOVA results of F(1,47) = 63.145 with a significance value of p < 0.001. The effect size was categorized as large with Partial Eta Squared = 0.573. However, learning motivation as a covariate did not significantly affect learning outcomes with F(1,47) = 0.001 and p = 0.974. Simultaneously, the model used in this research was significant with F(2,47) = 32.851 and p < 0.001 and contributed 58.3% to the variance of learning outcomes (R² = 0.583). Therefore, video-assisted Problem Based Instruction was proven effective in improving students’ learning outcomes in Lathe Machining Engineering

Abstract

The low learning results of students when learning the Frais Technique serve as the impetus for this study. It is believed that this is because students are not actively participating in teacher-centered learning models and their learning is not at its best. The purpose of this study is to ascertain how well the Project Based Learning learning paradigm affects the learning outcomes of SMK Negeri 1 Tanjung Raya students studying framing techniques. This study employs quantitative approaches and quasi-experimental research. 40 students made up the study's sample, and they were divided into two categories: the experimental category and the control category. The research period was carried out during the academic year 2024–2025's odd semester. The findings from the analysis of the data in this research suggest that the learning model centered around projects is significantly more influential than the conventional model to improve learning outcomes, the findings of the analysis illustrate that the average post-test results of the experimental class of 75.25 are greater than the control class with an average of 63.75. Based on the results of research and discussion, quasi-experimental research on the XI grade Frais Engineering Subject at SMK Negeri 1 Tanjung Raya can be concluded that there is an effectiveness of using project-based learning models on student learning outcomes where the value of learning outcomes in groups using project-based learning models is higher than conventional models.

Abstract

The integration of technology in vocational education has become a critical need to support 21st-century skills, especially in practice-based learning such as Basic Mechanical Engineering subjects. One promising innovation is the use of Augmented Reality (AR) media, which enables interactive three-dimensional visualization to help students concretely understand abstract concepts. This study aims to examine the effectiveness of lathe-based AR media in improving student learning outcomes and motivation in Grade X of the Machining Engineering Department at SMK Semen Padang. The research employed a quasi-experimental method using a non-equivalent control group design. The subjects consisted of two classes: the experimental class (using AR media) and the control class (using conventional learning methods). Data were collected using pre-tests and post-tests to assess learning outcomes and Likert-scale questionnaires to evaluate learning motivation. The analysis results showed that the use of AR media significantly increased student learning outcomes and motivation compared to traditional methods. Based on hypothesis testing and normalized gain score analysis, the AR media was found to be highly effective in the learning process. In conclusion, lathe-based Augmented Reality media proved to be an effective interactive learning tool that enhances students' academic performance and motivation, while also contributing to the development of innovative media in technical education.

Abstract

This study aims to measure the geometrical accuracy of complex object scanning using the Artec Leo 3D scanner. The scanned object is a wheel rim, with eight combinations of parameters including variations in distance (50 cm and 100 cm), scanning angle (45° and 90°), and lighting conditions (indoor and outdoor). Deviations were measured from four reference points on the scanned model and compared to a reference model. The results show that the Indoor configuration with a scanning distance of 50 cm and a scanning angle of 90° gives the smallest deviation of 0.025 mm (0.01%), while the Outdoor configuration with a scanning distance of 50 cm and a scanning angle of 45° produces the largest deviation of -3.275 mm (-1.80%). The overall average deviation of all combinations is -0.63 mm or -0.36%, indicating that the Artec Leo can produce high accuracy if configured with the right parameters. The smallest deviation was obtained under indoor scanning conditions with a scanning distance of 50 cm and a scanning angle of 90°.

Abstract

ABSTRACT The learning outcomes of Shielded Metal Arc Welding (SMAW) practical training among vocational high school students remain suboptimal and are presumed to be influenced by teachers' roles and the availability of workshop facilities. This study aimed to analyze the relationship between teachers' roles and workshop facilities and SMAW practical learning outcomes among Grade XI students of the Metal Welding Engineering program at SMK Negeri 2 Painan. The study employed a quantitative correlational approach. The population consisted of 12 students, all of whom were selected as the sample using a total sampling technique. Data on teachers' roles and workshop facilities were collected through questionnaires, while practical learning outcomes were obtained using an SMAW practical assessment rubric. Data were analyzed using descriptive statistics, prerequisite tests including normality, linearity, and multicollinearity tests, followed by multiple linear regression analysis. The findings revealed that the teacher's role had a positive and significant relationship with SMAW practical learning outcomes (r = 0.618; p < 0.05), whereas workshop facilities showed a positive but non-significant relationship (r = 0.629; p > 0.05). Simultaneously, teachers' roles and workshop facilities demonstrated a positive and significant relationship with SMAW practical learning outcomes (R = 0.707; R² = 0.500), indicating that both variables jointly explained 50.0% of the variance in students' practical learning outcomes. It can be concluded that the teacher's role is the primary factor significantly associated with SMAW practical learning outcomes, while workshop facilities serve as a supporting factor whose management should continue to be optimized to improve the quality of practical learning.
