Abstract

Haute couture-making techniques are critical competencies to be mastered by fashion engineering education (CEE) graduates. However, until now, many graduates have been unable to master these techniques optimally. Various studies and field phenomena confirm that they are unprepared for supporting knowledge (SK), socio-cultural, and psychological aspects. This phenomenon prompted us to measure practical learning readiness (PLR) in these three dimensions. In addition, we also examine the differences between dimensions and indicators and test the determination in constructing the PLR to determine the order of solving the problem. The survey was conducted on 386 CEE students with criteria who were currently studying haute couture (HC). The results of the descriptive analysis confirmed that psychological conditions (PC) and SK had a low level, while socio-cultural support had a high level. The results of the comparison test show that the three are generally similar, although there are notes in several indicators. Although all dimensions contribute significantly to constructing PLR, PC contribute the highest. This indicates that low PC are the first step to be addressed by CEE. Furthermore, several notes related to the decrease in knowledge-supporting practice are also the second effort that CEE must make to boost PLR in its students.

Abstract

The competency of vocational high school students is still said to be lacking in work readiness. This is caused by a lack of encouragement for oneself, family, school facilities, school environment, etc. This research aims to analyze the mediating role of work motivation in determining vocational school students' work readiness. This research uses an ex-post facto quantitative approach with the path analysis method. Research subjects in 3 vocational schools in machining engineering expertise in class XII with a total sample of 193 people. Data collection uses questionnaires, interviews, and documentation. Hypothesis testing in this study used SmartPLS 3 software. The findings show that work competency and industrial work practice experience can influence work motivation. Work motivation can directly influence students' work readiness. Indirectly, work competency affects work motivation through work readiness. Indirectly, industrial work practice experience affects work motivation through work readiness. It was concluded that work motivation plays a role in determining vocational school students' work readiness, especially in class XII machining engineering, followed by work competency and industrial work practice experience. So it is recommended to the vocational school community always to be motivated so that students are ready to work, have sufficient competence and experience, and always pay attention to the 3 things researchers discovered and discussed because vocational schools aim to work, continue, and become self-employed.

Abstract

Occupational Safety and Health (K3) is essential in machining engineering lessons at vocational schools because students often carry out practices involving many complex and sharp objects. This research aims to analyze occupational safety and health implementation in machining practical learning. This research uses an ex-post facto quantitative approach—research subjects in class XI machining engineering in four vocational schools with a sample of 172 people. Data collection uses surveys, observations, interviews, questionnaires, and documentation. The data analysis technique in this research is regression analysis. The findings show first, there is a significant influence between the application of K3 on learning machining practices. Second, the analysis results of the impact of the application of K3 on learning machining practices are in the weak category. Third, the results of the synthesis and evaluation show that there are four reasons or factors that influence the inadequate implementation of K3 in learning machining practices, including the lack of student knowledge about K3, the lack of school facilities related to K3, the lack of student perception regarding the importance of K3, and the lack of student behavior regarding K3 (motivation, discipline, honesty). This research concludes that applying K3 in learning machining practices is the task of stakeholders and every individual because health and safety at work are some of the supporting aspects towards success.

Abstract

The development of soft skills remains a critical challenge in vocational education, as the curriculum often prioritises technical competencies while neglecting systematic integration of interpersonal skills. This study aims to develop and evaluate the Peer-Engaged Project Application Model (PePA), a project-based learning framework designed to enhance communication, teamwork, and problem-solving through structured peer engagement. Employing a Research and Development (R&D) approach based on the ADDIE model, the research was conducted in the D4 Mechanical Engineering Program at Yogyakarta State University. The PePA model was tested on a group of 15 students in the Fabrication Construction Practices course. Data were collected through Likert-scale questionnaires, structured observations, and semi-structured interviews, and analysed using descriptive and inferential statistics, along with qualitative techniques. The implementation of PePA resulted in improved performance in soft skills, with average scores increasing from 3.03 to 3.65 (communication), 3.20 to 3.78 (teamwork), and 3.13 to 3.70 (problem-solving). The model was also rated as “very valid” by expert evaluators, with an average validation score ranging from 3.58 to 3.85. These findings suggest that PePA is a feasible and effective learning model for strengthening vocational students' soft skills in alignment with industry expectations. The model has potential applicability beyond engineering education and supports policy recommendations for integrating soft skills into vocational curricula.

Abstract

This study aims to increase production effectiveness in the fabrication process for the PT Pou Yuen Indonesia workshop construction by applying Lean Manufacturing and Manufacturing Cycle Effectiveness (MCE). The research used a quantitative descriptive method by taking representative samples from the overall production process in the cutting, setting, and submerged arc welding (SAW) lines. Data were collected through interviews, observation, documentation, and measurements of process time and transfer distance. The results show that the most effective cutting method is the method used by MSS, which applies a double-nozzle cutting process. In the setting process, the most effective methods are those used by MKR and MSS because they require fewer workers and have shorter process times than SST. In the welding process, the most effective method is the method used by MKR because flux is supplied during the welding process. Several types of waste were identified, including waiting time, transportation waste, inventory waste, motion waste, and processing waste. Applying the recommended process methods can reduce the total production process time by 9,011.99 seconds for one WF beam and reduce transfer distance by 2,070 m.

Abstract

This study successfully investigated the engine performance and emission characteristics of a dual injection system that uses both gasoline and ethanol fuels. The study utilized a microcontroller-based control system (PGM-FI) to substitute ethanol fuel injection for gasoline injection. Ethanol fuel was injected at the inlet with three different pressures: 1.0 bar, 1.2 bar, and 1.4 bar, while gasoline injector pressure was fixed at 2 bar. Results showed that substituting ethanol injection with a pressure of 1 bar resulted in a slight decrease in torque and power, but it was the best compared to the other pressures tested. The study found that the use of ethanol injection resulted in improved fuel economy at an ethanol injector pressure of 1 bar with a reduction in SFC of 8.89%. Exhaust emissions were also reduced, with a maximum reduction in CO emissions of 42.54% occurring at a pressure of 1 bar. Similarly, the lowest HC content in exhaust gas was observed at a pressure of 1 bar, which was reduced by 44.48%. However, the results highlighted that ethanol injection pressure could significantly reduce fuel consumption for case A-04 and increase the air-fuel ratio.
