Abstract

This research aims to (1) analyze the implementation of edupreneurship through a teaching factory in the light vehicle engineering skills program in Kutowinangun Muhammadiyah Vocational School; (2) analyze the driving factors for implementing edupreneurship through a teaching factory in the light vehicle engineering skills program at Muhammadiyah Kutowinangun Vocational School; and (3) analyzing the factors inhibiting the implementation of edupreneurship through a teaching factory in the light vehicle engineering skills program at Muhammadiyah Kutowinangun Vocational School. This qualitative research uses descriptive methods approach. Data collection was carried out by interviews, observations, and documentation. Research subjects are: principal, deputy principal curriculum fields, productive teachers, and students. The data analysis technique uses interactive analysis, starting from data collection and then reducing the data; after reduced, presented the data, and finally verified. The validity of the data was tested by triangulation. Findings in this research revealed that (1) Planning , organizing, implementing, and monitoring/evaluation, implementation of edupreneurship through the teaching factory , competency in light vehicle engineering skills at Muhammadiyah Kutowinangun Vocational School has gone very well in carrying out vehicle service and maintenance from inside and outside the school, the implementation of edupreneurship through the teaching factory makes a contribution to foster students' entrepreneurial spirit; (2) Factors driving the success of edupreneurship consist of: quality educational resources, adequate infrastructure both in quantity and quality, standard operational procedures according to industry standards, quality services, an established service marketing network, and students is to be directly involved in the work; (3) Inhibiting factors, namely the fluctuating number of customers, limited operational time, limited spare parts for all brands, and varying public perceptions of vocational school service results.

Abstract

Kesenjangan kompetensi lulusan Sekolah Menengah Kejuruan (SMK) dengan kebutuhan dunia usaha dan dunia industri masih menjadi tantangan utama dalam pendidikan vokasi Indonesia. Pola pembelajaran yang masih berorientasi pada penyampaian materi secara satu arah membuat siswa kurang memperoleh pengalaman langsung yang mencerminkan situasi kerja profesional. Praktik produktif di bengkel sekolah pun belum sepenuhnya merepresentasikan standar dan budaya kerja industri. Metode yang digunakan adalah Research and Development (R&D) dengan mengadaptasi model Richey dan Klein melalui tiga tahap: analisis dan perancangan, validasi internal oleh ahli, serta validasi eksternal. Validasi melibatkan dua praktisi industri otomotif dan tiga guru produktif SMK. Data diperoleh melalui wawancara terstruktur, angket skala Likert, dan tes unjuk kerja. Hasil penelitian menunjukkan bahwa model yang dikembangkan dinilai layak diterapkan, dengan skor validasi 87,14% dari praktisi industri dan 77,78% dari guru SMK. Model ini terdiri atas lima tahapan dengan pembagian peran yang jelas antara guru, siswa, dan mitra industri. Secara keseluruhan, model ini berpotensi meningkatkan kesiapan kerja dan daya saing lulusan SMK di era Industri 4.0.

Abstract

This study compares the engine performance and exhaust emissions of the Honda Vario 150 using four air filters: paper (OEM), foam, hybrid, and stainless steel. The testing used a quantitative experimental approach with a chassis dynamometer and an exhaust gas analyzer. The results showed that the stainless steel filter produced the highest peak power but significantly reduced engine torque due to a disrupted scavenging effect. Furthermore, the stainless steel filter generated the highest levels of emission pollutants (CO and HC) as it triggered an overly lean air-fuel ratio at high RPMs. Conversely, the paper filter (OEM) proved to be the most superior in maintaining maximum torque. In conclusion, the paper filter (OEM) is the best choice for daily commuting as it provides an optimal balance between torque, combustion efficiency, and clean emissions. A stainless steel filter is effective only for maximum-speed use and requires injection-system recalibration.

Abstract

This study compared the energy efficiency of 350 W and 400 W DC motors on the Niskala electric vehicle prototype under different gear ratios. Experimental testing was conducted using three gear combinations: 12T–17T, 12T–22T, and 12T–24T. The prototype was operated under each configuration, and energy consumption was measured with a Wh meter to determine efficiency as travel distance per unit of energy. The results showed that the 350 W DC motor combined with the 12T–17T gear configuration produced the lowest energy efficiency, at 248.3 km/kWh. This result indicates that the configuration did not provide optimal motor performance under the test conditions. In contrast, the 400 W DC motor with the 12T–24T gear combination achieved the highest energy efficiency, reaching 280.3 km/kWh. These findings indicate that higher motor power, combined with an appropriate gear ratio, can help maintain more optimal operating conditions. Therefore, the 400 W DC motor with the 12T–24T gear combination was the most optimal configuration for the Niskala electric vehicle prototype.
