Abstract

This study aims to develop a virtual reality-based learning model for automotive competence. The study was conducted using research and development method with the following steps: (1) analyzing the factual model; (2) constructing a conceptual model; (3) conducting model validation; (4) revising the model and determining the hypothetical model. The results indicated that: (1) factually virtual reality was still implemented in classical manner without using the right learning model; (2) the conceptual model was organized by incorporating elements of problem solving, flipped classroom, focusing on automotive competence, providing syntax for model implementation; (3) with a score of 85.7%, validators strongly agreed to implement this model, but with some improvements; (4) the concept was improved by providing information about competencies, reinforcing the steps of flipped classroom, focusing on automotive competencies, and clarifying the model steps. In conclusion, a hypothetical model was obtained through the following steps: (1) Preparation; (2) Simulation and Confirmation; (3) Exploration or Virtual Action; (4) Review of Material Exploration; and (5) Evaluation. Steps 1 to 3 were conducted out of class while steps 4 and 5 were conducted in class. This hypothetical model is ready to be applied in further study, specifically in limited trials.

Abstract

Berkembangnya teknologi di dunia otomotif yang sangat pesat, hal ini mendorong manusia untuk berpindah ke kendaraan menggunakan sistem EFI yang mempunyai campuran bahan bakar yang irit dan performa yang lebih optimal, serta menghasilkan emisi gas buang yang rendah. Pada sistem EFI pada pabrik dinilai kurang menghasilkan daya yang kurang maksimal, maka dari itu perlu dilakukan re-mapping ECU pada kendaraan sistem EFI, agar mampu menaikkan performa di banding setelan pabrik. Penggunaan pegas CVT yang tepat juga akan mempengaruhi performa yang dihasilkan oleh mesin kendaraan. Hasil penelitian: (1) Penggunaan ECU remapping dan pegas CVT racing menghasilkan torsi tertinggi pada mapping bahan bakar 5% sudut pengapian 2° dan limiter 11000 rpm torsi naik 15% di 4000 rpm dan 16% di 7000 rpm, (2) Daya tertinggi pada mapping bahan bakar 5% sudut pengapian 2° dan limiter 11000 rpm menggunakan pegas racing naik 13% di 4000 rpm dan 16% di 7000 rpm, (3) Specific fuel consumption terbaik setelah di lakukan remapping mencapai 19% pada 4000 rpm dan 6% di 7000 rpm saat mapping bahan bakar 5% sudut pengapian 2° dan limiter 11000 rpm, (4) Terdapat perubahan emisi gas buang setelah mapping bahan bakar 3% sudut pengapian 1° dan limiter 11000 rpm CO meningkat 32%, HC menurun 19%, CO2 naik 3%, dan O2 tetap. Lalu mapping bahan bakar 5% sudut pengapian 2° dan limiter 11000 rpm CO meningkat 91%, HC naik 42%, CO2 turun 2%, dan O2 tetap. Dan mapping bahan bakar 10% sudut pengapian 3° dan limiter 11000 rpm CO meningkat 5%, HC meningkat 6%, CO2 dan O2 sama dengan ECU standar.

Abstract

Work motivation is an important component in improving the professionalism of vocational teachers who possess teacherpreneur characteristics. Teachers are required to have more than technical expertise to meet the demands of the workforce in the Industrial Era 4.0. They must also demonstrate creativity, innovation, and entrepreneurial skills. The purpose of this study was to evaluate the influence of teachers’ work motivation and professionalism on the development of teacherpreneur characteristics. The research sample consisted of 264 productive teachers in the Automotive Vocational Technology field in Semarang City. The study employed a quantitative approach with an ex post facto research design. Path analysis and descriptive statistics were used to validate and analyze the questionnaire instruments. The results showed that work motivation had a significant direct effect on teacher professionalism (t = 4.69). The main conclusion is that increasing teachers’ work motivation positively contributes to the professional development of vocational teachers. This research highlights the importance of integrating entrepreneurial values into teacher development efforts within vocational education.

Abstract

This research aims to analyze the influence of the virtual learning environment and participant motivation on their understanding of the New Model Training material at the Astra Motor Training Center Semarang. After the global Covid-19 pandemic occurred, many training and education shifted to virtual learning methods. However, challenges such as lack of face-to-face interaction and potential distractions in the home or work environment can affect participant motivation. This research method is quantitative using surveys of training participants. The results of the analysis show that the virtual learning environment, especially through the Zoom application, has a positive influence on participants' understanding of the training material. Apart from that, participants' motivation also had a significant positive correlation with their understanding. The combination of an effective virtual learning environment and high levels of motivation provides a significant positive impact on understanding the training material. Based on the results of the t test, the following data was obtained: the virtual learning environment variable obtained a significant value of 0.037, which is smaller than 0.05. So these results show the influence of the virtual learning environment on the understanding of New Model Training participants at the Astra Motor Training Center Semarang and the learning motivation variable obtained a significant value of 0.002, which is smaller than 0.05. So these results show the influence of learning motivation on the understanding of New Model Training participants at AMTC Semarang. In conclusion, in the context of the New Model Training at AMTC Semarang, the virtual learning environment has a presentation of 3.8% and participant motivation has a presentation of 9.3% are important factors that are interrelated in increasing participants' understanding of the New Model Training material.

Abstract

Background of the problem The development of 21st century competencies requires someone to master various skills, including technology, information and communication skills. So it is an obligation for a teacher to provide distance learning or better known by the abbreviation PJJ. This shows that PJJ plays an important role not only in the development of 21st century competencies but also during the pandemic after COVID-19. However, from the information obtained, all students at Purwodadi National Development Vocational School have smartphones that are used in distance learning. The objectives of this research are: (1) to determine the effect of distance learning on work readiness, (2) to determine the effect of 21st century competencies on work readiness, (3) to determine the effect of distance learning and 21st century competencies on work readiness. The type of research used is quantitative research with a descriptive approach that is ex post facto in nature. Data collection techniques using documentation and questionnaires. The population and sample were 126 and 96 students. The data testing used is a validity test and a reliability test. Test data analysis requirements using normality test, linearity test, autocorrelation test, multicollinearity test, and heteroscedasticity test. Meanwhile, data hypothesis testing uses simple regression tests, multiple regression tests, T tests, F tests, R square tests (determinants) using the help of the SPSS data processing program version 24.0. The results of the analysis show (1) Distance learning on work readiness in the strongly agree category. (2) 21st century competency towards work readiness in the strongly agree category. (3) There is an influence of distance learning and 21st century competencies on work readiness. Which is proven by the results of the F test which shows a significance value (Sig) = 0.000 < 0.05 and the calculated F value = 131.046 > t table 1.41.
