Abstract

The increasing demand for energy efficiency and emission reduction in urban transportation requires innovative powertrain solutions. This study aims to design and analyze a parallel hybrid powertrain system for the Honda BeAT 110 eSP Scooter. The methodology involves integrating a 3000W BLDC Hub motor on a custom-made 6mm steel bracket arm, coupled with a 60V 27Ah lithium battery, without altering the main frame structure. Performance testing was conducted using a chassis dynamometer and on-road testing to measure fuel consumption, torque, and emissions. The results demonstrate that the hybrid system significantly improves vehicle performance. Fuel efficiency increased to 92 km per charge/refuel combination (compared to 38 km in standard mode). The electric motor produced a peak torque of 81.93 Nm, which is three times higher than the conventional engine's torque of 25.48 Nm. Furthermore, exhaust emissions (CO and HC) were reduced to 0% when operating in electric mode. Despite a 24 kg weight increase, the center of gravity shift remained within safe limits. This research concludes that a modular parallel hybrid system is a viable and efficient solution for urban scooters.

Abstract

This research investigates the various factors that affect entrepreneurial interest among vocational secondary school students enrolled in the electronics engineering program in Yogyakarta, Indonesia. The study identifies entrepreneurship as a crucial mechanism for fostering innovation, self-employment, and enhancing national competitiveness. It examines five primary determinants: self-efficacy, family support, entrepreneurial attitude, entrepreneurship education, and social and institutional support. A quantitative ex post facto methodology was utilized, involving 104 respondents chosen through proportional random sampling from three vocational institutions.  Data collection employed a validated four-point Likert scale questionnaire, with analysis conducted via simple and multiple linear regression techniques utilizing SPSS. The findings indicate that all five variables have significant and positive impacts on students' entrepreneurial interest, both independently and in combination. Entrepreneurship education and social–institutional support exhibit the most significant impact, underscoring the critical role of practical learning, mentorship, and supportive ecosystems in shaping entrepreneurial trajectories.  Self-efficacy and family support enhance motivation and confidence, while positive entrepreneurial attitudes promote perseverance and proactive engagement in opportunity recognition. These factors account for nearly half of the variance in entrepreneurial interest, thereby affirming the significance of the Theory of Planned Behavior and Social Cognitive Theory within vocational contexts. This study empirically enhances the discourse on entrepreneurship in technical and vocational education by highlighting the combined influence of psychological, familial, educational, and structural supports on the development of entrepreneurial intentions. Policy implications indicate that promoting entrepreneurship necessitates the alignment of curricular design, family involvement, and institutional policies to enhance entrepreneurial ecosystems within vocational education. Vocational schools can enhance student empowerment by fostering self-efficacy and offering accessible institutional resources, enabling the translation of entrepreneurial aspirations into sustainable ventures.

Abstract

Improving the teaching quality of vocational pre-service teachers requires integrative strategies that combine cultural values, motivation, and leadership development. This study examines the direct and indirect effects of Tamansiswa teaching values and motivation on teaching quality, with transformational leadership as a mediating variable. A quantitative longitudinal ex post facto design was employed. Data were collected from 697 vocational pre-service teachers in Yogyakarta, Indonesia, using structured questionnaires measuring Tamansiswa teaching values, motivation, transformational leadership, and teaching quality through validated Likert-scale instruments. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) to test measurement reliability, structural relationships, and mediation effects. The results indicate that motivation is the strongest predictor of teaching quality (β = 0.880), followed by transformational leadership (β = 0.238), while Tamansiswa teaching values show a smaller but significant direct effect (β = 0.088). Both Tamansiswa teaching values (β = 0.287) and motivation (β = 0.399) significantly enhance transformational leadership. Mediation analysis confirms that transformational leadership strengthens the effects of Tamansiswa teaching values and motivation on teaching quality. The structural model demonstrates good fit (SRMR = 0.056; NFI = 0.926). These findings position transformational leadership as a key mechanism through which indigenous values and motivation are translated into effective teaching practices. The study contributes to vocational teacher education by integrating culturally grounded values into a leadership-mediated model of teaching quality and recommends embedding value internalization, motivational support, and leadership development within pre-service teacher preparation programs.

Abstract

The global workforce’s rapid evolution and the complexities of Industry 4.0 necessitate a paradigm shift in Technical and Vocational Education and Training (TVET). Modern institutions are required to produce graduates who possess not only specialized practical skills but also robust non-technical competencies to navigate unpredictable professional environments. Despite the emphasis on workforce readiness, a significant research gap persists in contextualizing general TVET competencies into specific, actionable assessment frameworks for niche professions, such as the cook helper role in the culinary industry. This study aims to bridge this gap by conducting a qualitative Systematic Literature Review (SLR) of 30 peer-reviewed articles to identify core technical and non-technical competency variables. The findings reveal that while hard skills—such as culinary technique mastery, food safety, and hygiene—remain foundational, soft skills like adaptability, resilience, and effective communication are equally decisive for long-term career sustainability. This study successfully adapts these general TVET variables into specific, measurable indicators for cook helpers, emphasizing procedural precision and adherence to industry standards. Furthermore, the proposed assessment framework integrates work-based, interpersonal, and behavioral evaluations, offering a holistic measurement tool for SMK students. The study concludes that assessment frameworks in vocational education must transition from product-oriented testing to authentic, performance-based evaluations, particularly when implemented within Teaching Factory ecosystems.

Abstract

The phenomenon of job mismatch is one of the challenges in the development of vocational education and training because it indicates a discrepancy between the competencies possessed by graduates and the requirements of the jobs they hold. This situation can affect the effectiveness of training in preparing a workforce that meets the needs of industry, business, and the workforce (IDUKA). This study aims to analyze job mismatch in non-formal vocational training based on the results of a tracer study of alumni from the Rumah Gemilang Indonesia Training and Course Institute (LKP). The study employs a quantitative approach with a descriptive design. Data were collected through a tracer study using an online questionnaire involving 72 alumni of the Rumah Gemilang Indonesia Training Center. Data analysis was conducted using descriptive statistics, including frequency, percentage, and mean. The results indicate that the majority of alumni have entered the workforce, with 38.9% working in fields aligned with their training and 27.8% working in fields not aligned with the training they received. The indicator with the highest average score was “training that helps prepare for employment or entrepreneurship” (4.43), while the lowest-scoring indicator was “discrepancies between training content and the requirements of current jobs” (3.06). The research findings indicate that non-formal vocational training has made a positive contribution to improving graduates’ work readiness; however, there are still signs of a job mismatch, as evidenced by the proportion of graduates working outside their field of training, the need for additional training, and the demand for new competencies after entering the workforce. Therefore, the results of the tracer study should be utilized as a basis for program evaluation through curriculum updates, strengthened collaboration with industry partners, and enhanced practice- and technology-based learning to improve the relevance of graduates’ competencies to labor market needs.

Abstract

The rapid advancement of Artificial Intelligence (AI) and smart energy technologies has created new opportunities for enhancing vocational education, particularly in electrical engineering learning environments. Critical thinking skills are essential competencies for students in Electrical Installation Engineering programs, as they support problem-solving, decision-making, and analytical reasoning during practicum activities. However, electrical control system practicums in vocational schools are often conducted using conventional instructional approaches that provide limited opportunities for students to engage in higher-order thinking processes. This study aims to investigate the potential implementation of AI-Based Smart Grid Simulation as an innovative learning medium to enhance students’ critical thinking skills in electrical control system practicum learning. A qualitative case study approach was employed at SMKN 1 Tambun Utara, Indonesia. Data were collected through classroom observations, semi-structured interviews with teachers and students, and analysis of learning documents. The collected data were analyzed using the Miles and Huberman interactive model, including data reduction, data display, and conclusion drawing. The findings indicate that current practicum activities primarily rely on jobsheets and conventional laboratory equipment, which tend to emphasize procedural execution rather than analytical problem-solving. Teachers and students expressed the need for interactive learning media capable of visualizing complex electrical systems and simulating real-world operational scenarios. The study reveals that AI-Based Smart Grid Simulation has significant potential to support critical thinking development by enabling students to analyze system conditions, evaluate alternative solutions, and make informed decisions in simulated electrical control environments. These findings provide practical insights for integrating AI-driven smart grid technologies into vocational education and contribute to the development of innovative learning strategies that align with Industry 4.0 and Education 5.0 requirements.

Abstract

In the current digital era, quantitative data analysis remains a critical yet demanding stage of the research process, particularly for researchers without a strong statistical background. Complex analysis procedures, inconsistent method selection, and manual data handling increase the risk of human error and can threaten the validity of research findings. This study addresses this problem by designing and developing the CQR (Calculation of Quantitative Research) Application, a web-based predictive quantitative-analytics system intended to simplify statistical data processing for researchers regardless of their statistical expertise. The system was developed using the Research and Development (RD) method combined with the Waterfall model, comprising problem identification, data collection, system design, implementation, and testing, and was built using the Laravel 11 framework with a MySQL database. System design was guided by an analysis of functional and non-functional requirements and modelled using Use Case and Activity Diagrams. The developed system was evaluated through black-box testing across four core modules-user authentication and three data-upload calculator modules for the System Usability Scale (SUS). All eleven scenarios (100%) produced the expected output. A preliminary usability evaluation of the CQR Application itself, using the System Usability Scale with 32 student respondents, yielded a mean score of 76.09 (SD = 9.67), corresponding to an “Acceptable” rating and a curved grade of B. These findings indicate that the CQR Application is functionally reliable and perceived as usable, while quantitative benchmarking of analytical accuracy and processing time against established statistical software, together with a complementary User Experience Questionnaire evaluation, are identified as the immediate next steps for strengthening the system's scientific and practical contribution. The CQR Application is expected to help researchers, particularly those without extensive statistical training, conduct quantitative analysis that is more consistent, efficient, and credible.

Abstract

Background: The shift in demand for a workforce suited to the green economy has shifted the responsibility of vocational education toward producing graduates ready to contribute to the development of green jobs and industries. However, teachers of Generation Z face serious challenges in effectively managing green learning despite this need. This study aims to investigate the practices, challenges, and determinants of adopting green learning management by Generation Z teachers in vocational education in Indonesia Method: This study was qualitative in nature and employed a multi-case study design. The research subjects were 12 Generation Z teachers from 4 vocational schools with the Adiwiyata program that has been implemented for at least 4 years. Data collection was done through semi-structured interviews, field observations, and document analysis. Data were analyzed using qualitative thematic analysis based on Miles and Huberman's concept, which involved open, axial, and selective coding. Result: Green learning is implemented through learning orientation, contextual and project-based models, and multi-stakeholder roles. However, conceptual constraints, a lack of professional development, and inflexible curriculum structures limit its implementation. Also, its management is greatly influenced by individual, institutional, and work-demand factors. This indicates a gap between the theory of sustainability and classroom practice and the need for systemic alignment. Conclusion: With that in mind, to achieve green learning effectiveness, vocational education needs integrated curriculum reform, improved teacher capacity, and collaborative governance to support sustainable vocational education.
