Abstract

In the era of Industry 4.0, CO₂ laser cutting technology has been increasingly adopted across manufacturing, creative industries, and vocational education due to its precision, flexibility, and non-contact process. However, wood-based composites such as Medium Density Fibreboard (MDF) present challenges in laser machining, including thermal deformation, carbonization, and surface damage, necessitating further investigation into process parameters. This study designed and developed a CNC CO₂ Laser Cutting Machine with a 60 W laser source, dimensions of 160 × 100 × 85 cm, and a working area of 110 × 72 × 2 cm, integrating mechanical, optical, and control systems to improve efficiency and precision. The research method involved prototype design, fabrication, assembly, and iterative trials on acrylic, plywood, and MDF, with adjustments made to optimize power, cutting speed, and control stability. Surface roughness tests showed significant variation across materials, with MDF achieving an average Ra value of 6.25 µm (smooth) and acrylic achieving 0.85 µm (very smooth), indicating that acrylic provides superior aesthetic and precision outcomes, while MDF remains suitable for applications with moderate tolerance. The findings highlight that laser parameter optimization is critical for cut quality, and further refinements through jigs/fixtures and the addition of a rotary axis are recommended to enhance structural accuracy and expand application versatility.

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.
