Improving the milling machine competency learning outcomes through industrial project-based learning for vocational school students
No full textThis research is motivated by the implementation of conventional learning. Besides, student learning motivation is still low due to student activities that are less centered on making workpieces that are suitable for work in the industry. Learning outcomes show that only 55.88% of students reach Minimum Completeness Criteria (Kriteria Ketuntasan minimum or KKM). The design and learning of productive machining competencies that are in accordance with the needs of the industry influence students\u27 experience and learning outcomes. This study aims to analyze the results of industrial project-based learning (InPro-BL) milling machine competency learning outcomes in SMK Negeri 1 Semarang. The method used in this study is Class Action Research (CAR) through four stages: (1) planning, (2) implementation of actions, (3) observation and evaluation, (4) reflection. The samples were 34 students of class XII of Mechanical Engineering. The data were collected using product assessment instruments to measure dimensional accuracy, timeliness, level of disability, level of smoothness, and work attitude. This study was descriptive quantitative, and qualitative. The results of the study show that InPro-BL is effective in improving the learning outcomes of milling machine competencies. In Cycle I, there is an increase in learning outcomes, from 19 students who completed the KKM to 25 students or 73.52%. In Cycle II, there are 88.23% of students passed the KKM. These results can be improved by paying attention to the management of learning time through the block system, teacher\u27s understanding of industrial-project-based learning, and industry guest teachers mentoring every learning process
The pathway of strengthening the working readiness: A study on graduate students of Islamic Economics and Business Faculty of UIN Walisongo Semarang
No full textResearch on working readiness is not a new thing. Nevertheless, studies related to working readiness still become interesting topic considering the empirical phenomena that indicate low working readiness. In addition, the results of previous studies have not provided conclusive conclusions about the factors that explain working readiness. This study was conducted to test the working readiness model developed in this study empirically by using the variable approach of training, apprenticeship, self-efficacy, and locus of control. Data on training, apprenticeship, self-efficacy, locus of control, and working readiness were obtained through interviews using a questionnaire conducted to the final semester students of the Islamic Economics and Business Faculty of UIN Walisongo Semarang. The research model testing was done by using SEM as an approach to the analysis technique. The test results show that training and apprenticeship are proven capable of explaining self-efficacy and locus of control. The results of this study also show that training, apprenticeship, self-efficacy, and locus of control are appropriate variables to explain variations in working readiness
