Abstract

Dalam transportasi yang sedang marak saat ini, sepeda motor listrik memiliki beberapa keunggulan, seperti tidak menggunakan bahan bakar minyak dan tidak menimbulkan polusi sama sekali. Tujuan dari penelitian ini yaitu untuk menganalisa performa rancang bangun sepeda motor listrik MOLIVET yang menggunakan motor BLDC 500 W. Untuk pengujian yang dilakukan meliputi uji torsi, daya, tegangan, kecepatan dan kuat arus. Hasil dari penelitian ini untuk uji torsi tanpa beban sebesar 4,10 N.m dan pada saat dengan beban 90 kg torsi menjadi turun sebesar 3,51 N.m. Untuk hasil uji daya tanpa beban sebesar 0,39 Hp dan pada saat menggunakan beban 90 kg daya turn menjadi 0,29 Hp. Untuk tegangan pada baterai saat tanpa beban sebesar 49,07 V dan pada saat menggunakan beban sebesar 48,16 V. Untuk kecepatan rata-rata pada saat tanpa beban sebesar 31,97 KPH dan pada saat menggunakan beban 90 kg sebesar 26,89 KPH  Kata kunci: Motor Listrik BLDC ; Performa ; Torsi ; Daya

Abstract

Developing Industry-Based Job Sheets to Improve Student Competence in Electronic Fuel Injection (EFI) Tune-Up for the Light Vehicle Engineering Program at SMK Miftahul Huda. The main issue addressed in this study is students' low competency exam scores on EFI system materials, which result from the use of conventional learning media that do not meet industry standards. This research used a development research model with the Research and Development (R&D) approach, carried out through several stages: needs analysis, design, expert validation, limited trials, and effectiveness testing. Data was collected via expert validation questionnaires, practical questionnaires completed by teachers and students, and an effectiveness test using a pre-test and post-test control group design. Validation results showed that the job sheet was categorized as “highly valid,” with an average score of 4.85 from both media and material experts. The practicality test indicated that teachers and students rated the job sheet as “highly practical,” with an average score of 91.7%. Additionally, the effectiveness test demonstrated a significant improvement in the experimental class compared to the control class. The experimental class achieved an N-Gain score of 76.23% (high category), while the control class reached only 43.22% (medium category)
