Abstract

This study aims to determine the feasibility of the AutoCAD Engineering Drawing learning Jobsheet which was developed to increase interest in learning and analyze how much the technical drawing competence increases in automotive engineering education students at Muhammadiyah University of Purworejo. This study uses a four-D model device development model with the research subjects taken are students of Automotive Engineering Education, University of Muhammadiyah Purworejo totaling 40 students with a sample of two class groups. Collecting data using a questionnaire method and quantitative data analysis test by taking a percentage of the research results. The results of the research show that: (1) the AutoCAD Jobsheet development procedure includes define, design, develop, disseminate searches. (2) Jobshet AutoCAD technical drawings are suitable for use as learning media. This can be proven from media and material experts who show a percentage of 90%. The AutoCAD engineering drawing jobsheet also meets the criteria very good. This is shown through student responses which include small group trials obtaining an average percentage of 69% and large group trials obtaining an average percentage of 77.56%. The results of the validation of media experts and material experts as well as the results of the small group test and large group test indicate that the module is feasible to use. Comparison of student learning interest in the experimental class and control class with a score of 77.56 experimental class and control class score of 68.25. Based on these results, the AutoCAD technical drawing Jobsheet can increase student interest in learning.

Abstract

Kegiatan edukasi perawatan dan perbaikan sepeda motor matic mempunyai tujuan agar masyarakat pengguna sepeda motor matic di desa sangubanyu memiliki pengetahuan dan informasi tentang perawatan dan perbaikan sepeda motor matic baik yang dilakukan secara mandiri atau dilakukan dibengkel secara tepat. Metode pelaksanaan kegiatan diawali dengan persiapan, proses pelaksanaan, dan refleksi kegiatan. Proses persiapan dilakukan dengan diskusi dengan pamong desa dan karang taruna di Desa Sangubanyu. Dari hasil diskusi selanjutnya dibuat kesepakatan atau perjanjian kerja sama antara program studi pendidikan teknik otomotif dengan perangkat atau pamong desa Sangubanyu. Setelah kesepakatan perjanjian kerjasama dilanjutkan dengan pelaksanaan kegiatan yang diikuti oleh 18 orang pemuda. Setelah selesai kegiatan edukasi perawatan dan pemeliharaan sepeda motor matic dilanjutkan dengan tahap refleksi. Hasil akhir dari kegiatan pengabdian edukasi perawatan sepeda motor adalah peserta mendapatkan tambahan pengetahuan dan informasi terkait dengan cara melakukan perbaiki dan perawatan khususnya sepeda motor matic yang dapat dilaksanakan secara mandiri atau dengan melakukan perbaikan dan perawatan dibengkel secara tepat sesuai dengan pedoman perawatan dan perbaikan dari pabrikan. Hasil analisis dari angket refleksi kegiatan adalah sebagai berikut: 1) Pemahaman pemateri tentang materi perawatan dan perbaikan sepeda motor matic didapatkan skor 90 persen, 2) Manfaat materi kegiatan yang disampaikan mendapatkan skor 85 persen, 3) Tingkat rasa senang atau kepuasan peserta dalam kegiatan mendapatkan skor 90 persen. Berdasarkan data refleksi kegiatan pengabdian, disimpulkan bahwa pelaksanaan pengabdian mendapatkan respon yang baik, berharap ada tindak lanjut kegiatan edukasi dengan simulasi atau praktek secara langsung.

Abstract

This study aimed to determine the effect of angle changes on the primary fixed sheave and roller mass on torque, acceleration, engine power, and top speed of automatic motorcycles. This type of research is experimental research. The subjects in this study were 125 cc automatic motorcycles modified at the angle of the primary fixed sheave and the mass of the rollers. The angles of change were 14.5Ëš, 13.5Ëš, and 12.5Ëš; while the change in roller mass was 14, 13, and 12 grams. The testing began with tuning up the motorbike, then installing the fixed sheave and roller primary units that have been modified to the CVT (Continuously Variable Transmission) primary drive for further testing, and collecting the data using a dyno test tool. The results of this study show that: 1) Changes made to the primary drive pulley, especially to changes in the angle of the Primary fixed sheave and the weight or mass of the roller with the application simultaneously affect the torque, acceleration, engine power, and top speed of automatic motorbikes; 2) changing the angle of the primary fixed sheave (13.5Ëš) with the application of a roller weight of 13 grams can increase the maximum speed (top speed) by 0.4 (Kph) compared to the standard ones; 3) the increase in power and torque resulting from changes in the primary fixed sheave and the weight of the rollers applied at the same time do not significantly increase top speed and acceleration. Conversely, low power and torque do not necessarily reduce the top speed and acceleration of automatic motorcycles.
