<p class="p1">Cooperative problem-based learning (CPBL) has been introduced in engineering education as an effective technique for developing students' professional skills. Moreover, the method is essential for engaging students in learning and developing 21st century skills. However, students are usually "shocked" by such inquiry learning because they face sudden changes in the learning environment. In addition, its implementation in online learning is another challenge. Therefore, this study aims to identify students' perceptions of online CPBL performance in vocational pre-teacher education institutions. A self-reporting questionnaire was designed focusing on 21st century skills and distributed to 71 students after the end of the semester. Quantitatively, the instrument of the survey data was analysed using SPSS software. Quantitative data were analysed using descriptive statistics. The results show that online CPBL improved students’ collaboration, communication, and problem-solving skills. In general, they agreed that online CPBL improved the development of 21st century skills.However, the students faced some difficulties during the online discussion session due to internet connection problems and team member involvement. Details of the items are also discussed.</p>
Praktik pengelasan merupakan salah satu jenis praktik dengan durasi yang cukup lama. Oleh karena itu, diperlukan desain meja las yang ergonomis agar praktikan bisa praktik dengan aman dan nyaman. Tujuan penelitian ini adalah untuk mengevaluasi desain yang sudah ada dengan pendekatan analisis REBA kemudian mendesain ulang meja las yang lebih ergonomis. Teknik pengumpulan data dengan menggunakan teknik purposive sampling. Desain meja las yang diusulkan berdasarkan data antropometri 30 orang mahasiswa Pendidikan Teknik Mesin UNS angkatan 2018, 2019, dan 2020. Rancangan desain meja las ini menggunakan software SolidWork 2019. Perhitungan evaluasi resiko ergonomi dengan REBA dihasilkan skor 6 artinya diperlukan perbaikan segera dan memerlukan investigasi lebih lanjut. Hasil dari penelitian ini didapatkan desain rancangan meja las baru yang memiliki dimensi: panjang 42 cm, lebar 40 cm, dan tinggi 2.010 cm. Meja las ini juga menyediakan ruang untuk meletakkan mesin las di bawah meja las. Dengan demikian, perbaikan desain meja las akan meningkatkan efisiensi pelaksanaan praktik. Selain itu, praktik akan lebih aman dan nyaman karena meja las sudah menyesuaikan dengan postur tubuh rata-rata mahasiswa.
The development process of augmented reality generally requires devices and software with high compatibility so that they are the only obstacles in its development. The purpose of this study was to design and produce an application of learning media on the hydraulic cylinder of excavator based on augmented reality with Shapr3d for prospective students of automotive engineering education and to see the product feasibility level of the test subjects and validators. This learning media development stage consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. For the data method using direct observation and closed questionnaires. The questionnaire of the research results was analysed using Likert scale analysis. The results of the material expert validator with a score of 91.25% are very good category. Expert media design validator 92.5% is included in the very good category with a very proper name. The response to product use from three lecturers of automotive engineering education with a proportion score of 88.34% is in the very good category. The response to the use of the product was from twenty automotive engineering education students with a score proportion of 85.73% in the very good category. This that the application of automatic learning media on excavator hydraulic cylinder based on augmented reality with shapr3d based on Augmented Reality technology that has been developed can be used in elementary schools as a learning media for technical education.
<p>The development of this fast era makes competition to get a job to increase and become more difficult. In the current competition in the industrial world, it demands an increase in the quality of Human Resources through education. Vocational High School Education also prepares its graduates to go directly into the world of industry, but there are still limitations between the need for human resources in industry and the human resources produced by educational institutions. So therefore<strong> </strong>Curriculum development in Vocational High Schools is developed by prioritizing the needs of society, one of which is the need to be able to compete directly in industry. The aims of this research are: (1) To find out the alignment process between the SMK curriculum and industry. (2) Knowing how far the curriculum in SMK is aligned with the world of work in industry. (3) Knowing whether the SMK curriculum with industry is feasible. The method used in the automotive concentration curriculum alignment activities at SMKs uses a qualitative approach with descriptive research. Data collection techniques using techniquespupose sampling. Data collection techniques in this study used data collection techniques in the form of interviews, documents, and observations. The research documents include the Merdeka Curriculum, K13 Curriculum, service books, vehicle inspection sheets, and the results of the FGD minutes. Data analysis techniques in this study used content analysis techniques (analysis content). The research locations were limited to 2 SMK, namely: SMKN 2 Surakarta and SMK Warga Surakarta and three industries, namely: Toyota Nasmoco Ringroad, Daihatsu Adi Sucipto, and Suzuki Pabelan (PT. Solo Indonesia Utama). The data obtained is then juxtaposed between the curriculum and competencies in the industry in tabular form so that it can be seen which curriculum and competencies are not aligned. The results of this study are: The curriculum between automotive engineering vocational schools and industrial competencies is aligned, this is evidenced by the existenceforum grub discussion (FGD) between the SMK and the automotive industry.<em></em></p>
<p class="Abstract"><span lang="EN-US">Developing substitution products for mining equipment parts in local industries will have a significant economic impact. In addition, it will create independence in the supply of mining components, not relying on imports. However, Ceper metal casting area is still using traditional methods. This community service aims to improve product design and skills to support the supply chain availability of consumable mining equipment parts. Designing from existing components is not easy for small industries; therefore, it needs assistance from university experts. The method used design assistance in the production of bucket-adapter consumable parts. The mechanical engineering study program team assists with three stages of the process: (1) scanning, (2) triangulation, and (3) CAD modeling. The results showed that consumable parts had been successfully submitted to an industry partner to proceed to the following stages: (4) CAM and (5) machining. The consumable parts design improves quality and independence in manufacturing mining equipment parts. The local industry appreciated this activity because a good design can improve the process of developing consumable mining equipment parts.</span></p>
