Abstract

This study aimed to know: 1.) Describe the development of augmented reality books in the differential system; and 2.) Analyze the feasibility level of the application on the augmented reality book differential system. This study uses research and development (R&D) with the waterfall development design model, which includes four stages: analysis, design, coding or implementation, and testing. This study's sample was 11th-grade vocational high school students majoring in automotive light vehicle engineering. Application testing uses black-box testing by testing functionality without testing the internal structure or function of the application. The data collection used in this study included three media experts, three material experts, and 30 user responses (students) with data analysis techniques using descriptive analysis. The results of this study are (1) augmented reality books and applications on the android platform as learning media on the differential system, and (2) feasibility analysis by media expert validation with an average value of 80%, material experts with an average value of 84% and user responses with an average value of 90 % with a total value of 85% with the 'very eligible' category to be used as a learning medium in the differential system of chassis and power transfer competencies. Research products can be used as an attractive alternative learning media by utilizing digital technology that can display 3D objects in detail on the competence of the differential system.

Abstract

Augmented Reality (AR) is a technology that combines two-dimensional and or three-dimensional virtual objects into a real environment and then projects these virtual objects in reality in real time. Through this AR technology, users can see virtual objects added to the real world with contextual information. In education, AR has been widely used to complement the standard curriculum. Text, graphics, video, and audio can be superimposed into the student's real-time environment. This article aims to examine how the application and impact of the use of AR in vocational education. The Systematic Literature Review (SLR) method is used to identify, study, evaluate, and interpret Augmented Reality in vocational education. Research data were identified using the SLR method with the help of the PRISMA 2020 form. Article collection was carried out on the Science Direct database. There were as many as 454 articles. After being selected using inclusion and exclusion criteria, the data used were 14 articles. The study results reveal that AR is applied in learning as an innovative learning medium, a new approach to learning to improve students' understanding of knowledge and skills and provide a concrete learning experience. The integration of AR in education has the impact of increasing students' understanding and learning experience, promoting positive attitudes, making the learning process fun and interesting, and learning efficiency

Abstract

This study aims to evaluate the effect of feed rate (advance speed) on the wear of Creusabro 4800 saw blades during the cutting of low-carbon steel using a cold saw machine with a constant cutting speed of 107 m/s. The methods employed include literature review, direct field observation, interviews with technicians and operators, and data analysis from operational logbooks over a 40-day period. The results show that increasing the advance speed significantly accelerates tooth wear, reduces the number of cuts that can be performed, and affects the quality of the cut surface. An advance speed of 0.05 m/s produced 1200 cuts with 0.20 mm wear, while at 0.40 m/s, wear increased to 1.00 mm and the number of cuts dropped sharply to 300 units. Observed wear patterns included flank wear, rounding, and chipping, which were aggravated by thermal load and cyclic pressure due to the geometry of materials such as H-beams and C-channels. The optimal advance speed range was found between 0.10–0.20 m/s, where the number of cuts remained high and wear was within acceptable limits. This study recommends implementing a blade replacement logbook system, using active cooling systems, and evaluating the use of TCT blades as an alternative to improve cutting efficiency and tool life in industrial production settings

Abstract

This research aims to identify the challenges faced by students during the Field Work Practice (PKL) in the Automotive Light Vehicle Engineering (TKRO) program at SMK Negeri 4 Serang City. The focus of the study includes aspects of planning, implementation, assessment, as well as monitoring and evaluation of the PKL. The method used is descriptive quantitative, with data collection through questionnaires given to 63 students of class XII TKRO and interviews with supervising teachers. The results of the study show that students face various challenges, such as the mismatch between the PKL location and their field of expertise, insufficient preparation before the PKL, and the discrepancy between school material and industry practices. However, the planning, implementation, and evaluation of the PKL were rated as good to excellent. The industry's assessment of the students was also positive, but monitoring activities by the school are still limited due to resource constraints. This study recommends strengthening school-industry cooperation, improving preparation and monitoring systems, and placing students in PKL locations that align with their competencies. These findings are expected to serve as a reference in efforts to improve the quality of PKL implementation and the job readiness of vocational school graduates.

Abstract

This study aims to explore learning innovation skills in vocational teacher candidates in the Mechanical Engineering Vocational Education Program (PVTM) at Sultan Ageng Tirtayasa University. A qualitative approach with a case study method was used in this research. Data were collected through observations and in-depth interviews, utilizing interview guides and assessment rubrics to ensure the objectivity of the analysis. The research sample was drawn from 30% of students previously categorized as having low skills based on earlier studies, with the condition that they had completed the School Field Introduction course (PLP). The results showed that this classification was not entirely accurate. Some students categorized as “low” actually demonstrated strong competencies in innovative skills such as creative thinking, collaboration, communication, and problem-solving. The findings suggest that PVTM students have potential that can be developed into adaptive vocational teachers who are capable of facing the challenges of 21st-century learning. Strengthening teaching strategies and holistic evaluations is crucial to optimizing their abilities.

Abstract

Keselamatan dan kesehatan kerja adalah kepentingan bersama yang melibatkan berbagai aspek seperti hukum, kemanusiaan, ekonomi, dan tanggung jawab. Dengan terlibatnya aspek penting yang saling mengikat ini, manajemen K3 merupakan hal penting yang harus diperhatikan keberadaannya. Penelitian ini dilakukan di Bengkel Mitsubishi Dipo Internasional Pahala Otomotif Serang City. Peneltiian dilakukan dengan metode deskriptif-eksperimental dengan pengambilan data selama 30 hari. Poin klausul yang dibahas pada ISO 45001:2018 berupa poin klausul ke 6 yang membahas mengenai perencanaan (planning). Hasil penelitian menunjukkan bahwa sistem manajemen K3 pada lingkungan bengkel telah memenuhi syarat dalam sistem manajemen ISO 45001:2018 pada klausul ke 6 poin 6.1 Tindakan untuk mengatasi risiko dan peluang, 6.1.2 Identifikasi bahaya dan penilaian risiko dan peluang, dan 6.1.2.2 Pengkajian risiko K3 dan risiko terkait sistem manajemen K3 lainnya. Bagaimanapun, ISO 4500:2018 telah menjadi panduan untuk semua lingkungan kerja yang melibatkan aturan K3 didalamnya sebagai bentuk pencegahan resiko terjadinya kecelakaan kerja.
