Abstract

Graduates of the Vocational Education in Mechanical Engineering (PVTM) program at Ivet University have predominantly pursued careers in relevant fields of expertise. A total of 87% of alumni work as educators. According to the graduate profile, PVTM alumni are also projected to become industry instructors and entrepreneurs. However, a key issue arises regarding the implementation of the Indonesian National Qualification Framework (KKNI) curriculum in PVTM, which remains focused on less adaptable skills, leading to concerns about graduates' competencies in the industry. By integrating the concept of Outcome-Based Education (OBE) with the Indonesian National Work Competency Standards (SKKNI) in the technical schema, graduate competencies are expected to be strengthened and better recognized in the industry. This study aims to design an OBE-integrated curriculum aligned with SKKNI to support the implementation of the Merdeka Belajar Kampus Merdeka (MBKM) initiative in the Vocational Education in Mechanical Engineering program at Ivet University. The research employed the Borg and Gall research and development methodology, culminating in a hypothetical model represented by a draft curriculum ready for trial implementation. The findings resulted in an OBE-integrated curriculum draft aligned with SKKNI, targeting the Level IV Welding Inspector occupational schema, comprising: (1) Eighteen study topics forming eight core courses within the program; (2) A curriculum integrated with three key concepts: OBE, SKKNI, and Welding Inspector; (3) Study topics applicable to Merdeka Belajar activities such as independent studies, student exchange programs, and projects; (A survey of 10 expert respondents, where 83% strongly agreed, 12% agreed, and 5% were neutral regarding the draft curriculum's feasibility. Thus, it can be concluded that the developed curriculum draft is suitable for trial implementation.

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

This study aims to develop a portfolio assessment instrument based on the Indonesian National Qualifications Framework (KKNI) and the National Higher Education Standards (SN-DIKTI) to support the implementation of the Merdeka Learning Campus Merdeka (MBKM) program in the Outcome-Based Education (OBE) curriculum. The research subject is the Mechanical Engineering Vocational Education (PVTM) study program at IVET University. The research method uses the 4-D model (Define, Design, Develop, Disseminate), which consists of the stages of needs definition, instrument design, validation, and development. The developed instrument was designed in a five-level Likert scale format, covering three main aspects: cognitive, affective, and psychomotor. The results of validation by experts showed a high level of validity with an average score of 0.85 (very valid). Testing was conducted in the Research Methods course involving 30 students, resulting in an average portfolio assessment score of 78.5 (good). Feedback from lecturers showed that this instrument increased the accuracy of the assessment, while students found the instrument easy to understand and use.

Abstract

Perkembangan teknologi di bidang otomotif sebagai alat penunjang kehidupan yang dapat memberikan kemudahan dan kenyamanan untuk memenuhi kebutuhan manusia. Penggunaan sepeda motor yang terus meningkat dari tahun ke tahun berdampak pada konsumsi bahan bakar minyak bumi yang meningkat pula, oleh karena itu perlu dilakukan inovasi pada kendaraan agar mampu menurunkan tingkat konsumsi bahan bakar tanpa mengurangi performa mesinya. Seiring bertambahnya usia pakai kendaraan matic akan mengakibatkan penurunan preforma mesin sehingga perlu diadakan usaha-usaha untuk meminimalisir penurunan performa kendaraan. Hasil penelitian : 1). Pengaruh sudut kontak drive pulley 13,5° dan roller 10 gram menghasilkan torsi lebih kecil dari standarnya di 4000 rpm. Sudut kontak 13,5° dan roller 10 gram torsi turun 3,77%. Sudut kontak 13,5° dan roller 13 gram torsi turun 0,47%. Sudut kontak 14° dan roller 10 gram torsi naik 2,83%. 2).

Abstract

This research aims to determine the effect of adding capacitors and variations in spark plugs on the Exhaust Gas Emission content of the Honda Supra X 100cc motorbike. This research method uses an experimental method with descriptive statistics. The object used in this research is a 100cc Supra The place of research was carried out at the PVTMO Ivet Semarang Automotive Workshop. The technique used in collecting data is conducting experiments by testing the objects to be studied and recording the necessary data. Data analysis in this research uses descriptive statistics, namely describing or describing the data that has been collected as it is without making general conclusions or generalizations. The resulting data includes the amount of CO, HC, CO2, O2, lambda, and AFR. The research results showed that the highest CO gas content was produced by Spark Plug Racing using additional capacitors with an average value of 6.80%. Meanwhile, the lowest CO gas content is created by original or standard spark plugs without using additional capacitors with an average value of 5.93%. Meanwhile, the highest HC was produced by Racing Spark Plugs using additional capacitors with an average value of 485 ppm, almost the same as that produced by original spark plugs with the addition of capacitors. Meanwhile, the lowest HC gas content is produced by original or standard spark plugs without using additional capacitors with an average value of 378 ppm.

Abstract

The purpose of this study is to analyze the needs of teachers and students for learning media, to determine the feasibility of learning media, and to measure the effectiveness of this learning media on Shiva learning outcomes. This type of research is Research and Development (R&D). With the validation of the research instrument, it is then continued with the research procedure using 10 stages, and quantitative descriptive data analysis techniques. The results of the media feasibility test obtained a percentage of 95% for the media assessment so that the product was categorized as "very feasible", and 93% for the assessment of material experts so that the product was also categorized as "very feasible". Student learning outcomes at n-gain value get an average score of 0.8547, meaning that the increase in student learning outcomes is in the "high" category. The researcher suggested that the use of android-based learning media to improve student learning outcomes on product branding materials could be an alternative and reference for learning media.
