Abstract

Although the teaching profession has a strategic role in ensuring the quality of vocational education, not all students in education study programs show a strong interest in pursuing a career as teachers. This study aims to analyze the effect of students’ perceptions of the teaching profession on interest in becoming teachers among students of the Mechanical Engineering Education Study Program at Universitas Negeri Padang. This study used a quantitative approach with an associative ex post facto design. The population as well as the research sample consisted of 72 students from the 2022 cohort, determined through a total sampling technique. Data were collected using a four-point Likert-scale questionnaire distributed through Google Forms. The research instrument consisted of 35 valid items with a Cronbach’s Alpha reliability coefficient of 0.949. Data were analyzed using descriptive statistics, normality testing, linearity testing, and simple linear regression with the assistance of SPSS. The results showed that students’ perceptions of the teaching profession were in the good category, with the largest percentage of 36%, while interest in becoming teachers was also in the good category, with the largest percentage of 44%. The regression analysis produced the equation Y = 10.348 + 0.448X, while the t-test obtained a value of 4.718 with a significance of 0.000 < 0.05. These findings indicate that students’ perceptions of the teaching profession have a positive and significant effect on interest in becoming teachers. The conclusion of this study affirms that the more positive students’ perceptions of the teaching profession, the higher their interest in choosing a teaching career. The implications of this study emphasize the importance of strengthening understanding, experience, and a positive image of the teaching profession in vocational education programs so that students’ interest in becoming teachers can develop more optimally.

Abstract

In recent years, the exploration of polyvinyl alcohol (PVA) composites has garnered significant attention due to their versatility applications in aqueous environments. However, despite their promise, neat PVA exhibit limitations such as significant mechanical degradation under repeated swelling cycles. This study investigates the durability and tribological performance of polyvinyl alcohol (PVA) composites reinforced with nickel-iron layered double hydroxide (LDH) and tannic acid (TA) under repeated swelling cycles. Building on previous research that explored composite preparation and initial characterization, this research emphasizes the effects of cyclic swelling on wear resistance, friction behavior, and mechanical properties. Tribological tests were conducted to evaluate the coefficient of friction (COF) and wear rate before and after multiple swelling cycles, alongside tensile strength and strain measurements. The results revealed that the PVA/TA2/LDH2 composite, containing the highest additive content, exhibited the lowest wear rate of 11.52 × 10⁻⁵ mm³/Nm after 3 swelling cycles, demonstrating superior resistance to material degradation. Although PVA/TA2/LDH1 exhibited a slightly lower COF, its wear rate was higher due to reduced reinforcement. Compared to neat PVA, which showed a COF increase from 0.45 to 0.53, the PVA/LDH/TA composites retained their tribological stability, with only a marginal increase in COF and wear rate. Similarly, tensile strength of PVA/TA2/LDH2 decreased by only 11% after 3 cycles (from 33.3 MPa to 30 MPa), while neat PVA experienced a 25.5% reduction (from 30 MPa to 22.5 MPa). These findings highlight the potential of PVA/LDH/TA composites for applications in aqueous environments, offering significantly enhanced long-term performance and reliability.

Abstract

Anti-UV films and composites play a critical role in protecting materials from ultraviolet-induced degradation, which can weaken polymers, reduce product lifespan, and compromise performance in sectors such as food packaging, outdoor coatings, and biomedical devices. The growing emphasis on sustainability and the need for environmentally friendly protective materials have further accelerated research on UV-shielding technologies that incorporate biopolymers, multifunctional additives, and renewable resources. This study presents a comprehensive bibliometric analysis of global research on anti-UV films and composites over the period 2014–2024. Data were retrieved from the Scopus database and analyzed using Bibliometrix (R package) and VOSviewer were employed to analyze publication patterns, map keyword networks, and visualize thematic evolution, as these tools enable robust quantitative and structural mapping of large bibliographic datasets. Three dominant thematic clusters were identified: (i) nanoparticle-based UV shielding using inorganic fillers such as ZnO and TiO₂, (ii) multifunctional films integrating UV protection with antibacterial and antioxidant properties, and (iii) biopolymer-based matrices emphasizing mechanical durability and environmental sustainability. These clusters highlight the convergence of performance, sustainability, and multifunctionality as key drivers shaping current research directions. Despite significant progress, the analysis reveals limited attention to scalability, industrial compatibility, and long-term performance evaluation. The findings underscore the need for future research to incorporate pilot-scale processing, life-cycle assessments, and interdisciplinary collaboration to bridge the gap between laboratory formulations and commercial implementation. Overall, this bibliometric study provides a consolidated understanding of the evolution and research landscape of anti-UV films and composites.

Abstract

This study examined the implementation of Problem-Based Learning (PBL) and its effect on Grade X Machining Engineering students’ cognitive achievement in Technical Drawing, particularly orthogonal projection. The study used a quantitative quasi-experimental design with a non-equivalent control group. The participants were 70 students at SMK Negeri 5 Padang, divided into an experimental class taught using PBL and a control class taught using conventional instruction. Data were collected through pretest and post-test scores using a validated multiple-choice test on orthogonal projection. The final instrument consisted of 28 valid items with a KR-20 reliability coefficient of 0.914. Descriptive statistics, Shapiro-Wilk normality tests, Levene’s homogeneity test, and an independent samples t-test were used for data analysis. The results showed that both groups improved after instruction, but the experimental class achieved a higher increase. The mean score of the experimental class rose from 53.57 to 79.28, while the control class increased from 53.67 to 64.29. The t-test showed a significant post-test difference between groups, t (68) = -10.152, p < 0.001. These findings indicate that PBL supports stronger cognitive achievement in orthogonal projection learning by engaging students in investigation, discussion, presentation, and evaluation. The findings directly recommend PBL for visual technical topics in vocational classrooms.

Abstract

This study examined the effects of Training Quality and Work Motivation on Teacher Performance among vocational high school teachers. A quantitative explanatory survey was conducted involving all 31 teachers at SMKN 7 Sijunjung using a census sampling technique. Data were collected through a structured questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4.1.0.8. The measurement model demonstrated satisfactory reliability and validity. Training Quality had the strongest positive effect on Teacher Performance (β = 0.646, p < 0.001), followed by Work Motivation (β = 0.416, p < 0.001). Together, both variables explained 64.9% of the variance in Teacher Performance (R² = 0.649). Enhancing teacher performance requires integrating high-quality professional development with strategies that strengthen teachers' work motivation
