Abstract

The advancement of technology demands learning media that are more engaging and interactive. In the Power Transmission Systems course, instruction is still dominated by lectures, resulting in suboptimal student comprehension. This study aims to examine the effectiveness of a differential tutorial video as a learning medium. The research employed a pre-experimental one-group pretest–posttest design involving 30 Automotive Engineering students. A test instrument was administered before and after the intervention. Normality tests showed that pretest data were normally distributed, while posttest data were not, leading to the use of the Wilcoxon Signed Rank test. The results indicated an improvement in learning outcomes, with 30 positive ranks. A Z-value of –4.798 and p = 0.000 confirmed a significant difference. The effect size of 0.876 indicated a very strong impact. Overall, the tutorial video proved effective in enhancing students’ understanding of differential concepts through visual and auditory stimulation.Keywords: Video Tutorial, Differential, Learning Outcomes, Learning Media, Power Transmission System

Abstract

Penelitian ini membahas peningkatan performa mesin sepeda motor matik Yamaha Aerox 155cc melalui optimasi sistem Continuously Variable Transmission (CVT). Fokus kajian adalah perubahan sudut primary pulley dan pemilihan massa roller, karena keduanya menentukan karakter penyaluran torsi dan daya. Metode eksperimen menggunakan desain faktorial pada dua sudut primary pulley (14° standar dan 13,5° modifikasi) dan tiga jenis roller (standar, sliding 12 gram, sliding 10 gram). Uji performa dilakukan dengan chassis dynamometer pada rentang 3000–9000 rpm dengan tiga pengulangan tiap konfigurasi. Hasil menunjukkan bahwa kombinasi primary pulley 13,5° dan sliding roller 10 gram meningkatkan daya maksimum dari 7,35 kW menjadi 9,52 kW atau sekitar 22,8% dibandingkan kondisi standar, sedangkan torsi tertinggi 11,70 Nm dicapai pada pulley 13,5° dengan roller standar. Temuan ini menegaskan bahwa pengaturan sudut pulley dan konfigurasi roller yang tepat mampu mengoptimalkan transmisi CVT dan menjadi dasar teknis bagi strategi tuning yang efisien dan ekonomis. This study investigates improvement of Yamaha Aerox 155cc scooter performance through optimization of the Continuously Variable Transmission (CVT) system. The analysis focuses on primary pulley angle and roller mass selection, since both parameters govern torque and power delivery. A factorial experimental design used two primary pulley angles (standard 14° and modified 13.5°) and three roller types (standard, 12 g sliding, 10 g sliding). Performance tests were conducted on a chassis dynamometer over 3000–9000 rpm with three repetitions for each configuration. The combination of a 13.5° primary pulley and a 10 g sliding roller increased maximum power from 7.35 kW to 9.52 kW, or about 22.8% above the standard configuration, while the highest torque of 11.70 Nm was obtained from the 13.5° pulley with standard rollers. These findings show that appropriate pulley-angle adjustment and roller configuration can optimize CVT transmission and support efficient and economical tuning strategies.

Abstract

Penggunaan sepeda motor yang terus meningkat berkontribusi pada pencemaran udara melalui emisi gas buang. Penelitian ini menganalisis pengaruh pemasangan Ignition Booster tipe plasma pada sistem pengapian terhadap emisi gas buang sepeda motor Honda Beat FI 2013. Penelitian deskriptif-eksperimental ini dilakukan pada kondisi putaran idle menggunakan four-gas analyzer, dengan tiga kali pengulangan untuk kondisi standar dan setelah pemasangan Ignition Booster. Hasil menunjukkan penurunan emisi karbon monoksida (CO) sebesar 23,52% (0,513% menjadi 0,39%), hidrokarbon (HC) 11,05% (60,33 ppm menjadi 53,66 ppm), dan karbon dioksida (CO₂) 2,12% (4,7% menjadi 4,6%), sementara kadar oksigen (O₂) meningkat 49,63% (8,18% menjadi 12,24%). Seluruh nilai emisi berada jauh di bawah ambang batas standar Euro 3. Temuan ini mengindikasikan bahwa penguatan energi percikan melalui Ignition Booster mampu meningkatkan kualitas pembakaran dan berpotensi menjadi solusi retrofit sederhana untuk menurunkan emisi kendaraan roda dua. The rapid growth of motorcycle use substantially contributes to urban air pollution through exhaust emissions. This study examines the effect of installing a plasma-type Ignition Booster on the ignition system of a Honda Beat FI 2013 motorcycle on its exhaust-gas composition. A descriptive experimental design was applied at idle speed using a four-gas analyzer, with three repeated measurements for the baseline and booster conditions. The Ignition Booster reduced carbon monoxide (CO) emissions by 23.52% (0.513% to 0.39%), hydrocarbons (HC) by 11.05% (60.33 ppm to 53.66 ppm), and carbon dioxide (CO₂) by 2.12% (4.7% to 4.6%), while oxygen (O₂) concentration increased by 49.63% (8.18% to 12.24%). All emission levels were well below the Euro 3 limits. These findings indicate that strengthening spark energy via an Ignition Booster improves combustion quality and offers a simple retrofit strategy to reduce emissions from existing two-wheeled vehicles.
