Abstract

The demand for increasingly diverse product designs and specifications in the manufacturing industry requires  Computer Numerical Control (CNC) machine operators to have high technical skills and strong self-efficacy and creativity. High self-efficacy allows operators to be more confident in applying their technical skills, while creativity helps them solve problems and challenges during the production process. This study aims to improve students' self-efficacy and creativity by applying the Peer-Project Based Learning (Peer-PjBL) model, which combines aspects of project-based learning with peer-to-peer learning. The method used in this research is Classroom Action Research (PTK), which consists of two implementation cycles. Each cycle involves planning, implementation, observation, and reflection stages. The subjects of this study were 20 students who took the CNC Machining Technology course at Universitas Negeri Yogyakarta. Data were collected using a questionnaire that measured self-efficacy and student creativity indicators and then analyzed descriptively. The results showed that applying the Peer-PjBL method significantly increased students' self-efficacy and creativity in each research cycle. This improvement can be seen in students' ability to face new challenges independently, as well as their ability to generate diverse creative ideas in solving problems. This research makes an important contribution to the development of learning methods in vocational education by emphasizing the improvement of technical abilities and non-technical skills, such as self-efficacy and creativity, which are needed in the modern world of work.

Abstract

The demands of the workplace in the Industry 4.0 era require vocational education to produce graduates who not only master technical skills but also possess non-technical (or "soft") skills, such as communication, teamwork, adaptability, and problem-solving. This study aims to identify and analyze effective institutional practices in developing soft skills in vocational higher education. This research employs a qualitative case study approach, using semi-structured interviews with department heads, study program heads, and lecturers at two State polytechnics in Indonesia. Thematic analysis reveals that soft skills development is implemented through four primary strategies: student orientation, internal training, external training with industry, and integration into the curriculum. These four strategies form a holistic institutional model to strengthen students' personal and professional readiness for the workplace. The research findings emphasize the importance of systematic management of soft skills development to produce vocational graduates who are technically competent, possess strong character, and are highly competitive.

Abstract

This study aims to analyze the direct influence of achievement motivation and workshop facilities, as well as the indirect influence through independent learning and practical machining learning on students' machining competency. A quantitative approach using path analysis, assisted by the SPSS program, was used to determine the causal relationships among variables. Before conducting the path analysis, the data met the prerequisite tests for normality, linearity, multicollinearity, and homoscedasticity, making it suitable for parametric analysis. The results show that achievement motivation and workshop facilities have a positive and significant influence on machining competency, both directly and indirectly through increasing independent learning and the effectiveness of practical machining learning. Overall, these findings confirm that both student and learning environment factors play an important role in the development of machining competency. The results of this study provide an empirical basis for the development of vocational learning strategies that are more effective and aligned with the needs of the modern manufacturing industry.

Abstract

Vocational higher education is required to produce graduates with Computer-Aided Manufacturing (CAM) competencies that align with rapidly evolving industrial demands. However, variations in learning models across institutions often result in inconsistent competency outcomes. This study aims to explore and analyze CAM learning models implemented in Diploma-level vocational higher education and examine their relevance to workplace requirements. Employing a qualitative multi-case study approach, data were collected from four vocational higher education institutions in Indonesia through observations, document analysis, and semi-structured interviews with lecturers and industry partners. The findings identify three dominant CAM learning models: textbook-based, industry-based, and internet literacy-based learning. The industry-based model demonstrates the most substantial alignment with workplace competencies, particularly in problem-solving and adaptability, while the textbook-based model remains effective for foundational conceptual understanding. Internet literacy-based learning supports independent learning but requires structured guidance to ensure depth of competency. The study highlights the importance of integrating soft skills, including leadership and problem-solving, into CAM learning models to enhance graduates’ employability in Industry 4.0. These findings provide practical insights for curriculum designers and vocational institutions in developing more industry-responsive CAM learning strategies

Abstract

Welding practice in vocational education must align with industry standards to produce competent and work-ready graduates. This study evaluated the effectiveness of WPS-based job sheets in improving students’ learning outcomes in carbon steel welding practice. A quasi-experimental pre-test–post-test control group design was conducted with 42 vocational mechanical engineering students. Two intact classes were assigned as the experimental group using WPS-based job sheets and the control group using conventional job sheets. Data were collected through performance assessments covering understanding of WPS, welding process skills, weld quality, and procedural and occupational safety and health (OSH) compliance. Data were analysed using descriptive statistics, independent-samples t-tests, normalized gain (N-gain), and Cohen’s d effect size analysis. Significant differences were found between the groups across all domains (p < .001). The experimental group achieved higher N-gain scores (0.78–0.84) than the control group (0.53–0.61), with very large effect sizes (d = 2.41–2.62). These findings demonstrate that WPS-based job sheets effectively improve vocational students’ welding learning outcomes.
