Abstract

This research investigates the impact of Continuously Variable Transmission (CVT) roller weight on fuel consumption and engine performance in motorcycles. The study involved experimental testing of motorcycles fitted with rollers of varying weights (9 grams and 12 grams) to evaluate their effects on fuel consumption, and overall engine performance. This study concludes that the choice of CVT roller weight significantly affects both fuel consumption and engine performance, with potential implications for optimizing motorcycle efficiency based on user preferences and riding conditions. This study found that the 9-gram roller produced greater torque and power (7.85 Nm at 3,500 RPM, 8.45 hp at 6,500 RPM) than the 12-gram roller, but its fuel consumption was higher at low RPM (SFC 0.07 kg/hp.h at 1,500 RPM).

Abstract

Effective education is crucial for instructing students to attain competencies aligned with the curriculum of their educational level. This study aims to assess the teaching profession and its correlation with teacher performance, professionalism, and teacher confidence in connection with student learning outcomes. This research was carried out on vocational educators in West Sumatra who have participated in the teacher professional education program. This research employs the Partial Least Squares Structural Equation Modeling (PLS-SEM) analytical technique. Data was gathered through purposive sampling from vocational educators in vocational high schools in West Sumatra. The findings indicated that teacher professional education (X1) exerts a significant direct influence on Teacher Performance in the Merdeka Curriculum (Z1), Professional Teachers in Indonesia (Z2), and Self-Confidence (Z3), in addition to Student Learning Outcomes (Y1). Notably, professional teachers have a substantial impact on the execution of the Merdeka Curriculum in contemporary vocational high schools, as evidenced by the largest path coefficient of the relationship between X1 and Z1 (0.558). Professional education for vocational high school teachers in West Sumatra has a significant effect on teacher professionalism, self-confidence and improving student learning outcomes, even though Indonesia is implementing a new curriculum, namely the Merdeka curriculum, teachers are still ready to be professional, confident to have an impact on student learning outcomes.

Abstract

The high unemployment rate in Nagari Sialang Gaung, reaching 30–40% of the productive-age population, poses a serious problem hindering community welfare. This situation is paradoxical given the significant opportunities in the motor vehicle service sector, driven by an estimated 10% annual increase in the number of motorcycles. Unfortunately, this market potential remains largely untapped due to the lack of technical and entrepreneurial skills among the unemployed youth. The Prodi and Nagari Integration Program (PIPN) Life Skill was established to bridge this gap with a dual objective, enhancing motorcycle mechanic competence and fostering entrepreneurship through hands-on practice. The program was comprehensively designed, encompassing needs analysis, development of a curriculum based on local potential, technical training (covering both conventional and EFI injection systems), instruction in workshop management, and post-training business mentoring. Program results indicate a significant increase in participant competence, with 85% demonstrating the ability to perform repairs independently and 30% having successfully initiated small-scale repair businesses. This success underscores the critical importance of synergy between universities and village governance in empowering communities based on sustainable local potential, thereby contributing directly to the achievement of the Sustainable Development Goals (SDGs).

Abstract

SMK memiliki peran dalam peningkatan kecerdasan, pengetahuan, kepribadian, akhlak mulia, dan keterampilan sebagai bekal untuk hidup mandiri dan siap kerja. Tamatan SMK diharapkan mempunyai kompetensi yang baik agar siap pakai dan terampil, sehingga memudahkan industri untuk medapatkan tenaga kerja sesuai posisi yang kebutuhan. Tetapi berdasarkan data BPS pada Agustus 2020, TPT SMK adalah 8,49% dan tertinggi dibandingkan jenjang pendidikan lainnya. Masalah ini terjadi karena belum selarasnya antara kompetensi tamatan SMK dengan kebutuhan industri. Penyelarasan kompetensi tamatan SMK terhadap kebutuhan industri tergantung pada sumber daya serta sarana/prasarana yang dimiliki SMK. Permasalahannya sarana/prasarana praktik yang dimiliki SMK masih sedikit dan kondisinya kurang memadai. Tamatan SMK Jurusan Teknik Sepeda Motor seharusnya memiliki pengetahuan dan keterampilan teknologi programmed fuel injection sepeda motor. Maka kegiatan ini bertujuan meningkatkan kompetensi siswa SMK melalui rancang bangun simulator dan pelatihan teknologi programmed fuel injection sepeda motor. Berdasarkan evaluasi pelaksanaan kegiatan, terdapat peningkatan kompetensi siswa tentang teknologi programmed fuel injection sepeda motor, sehingga diharapkan kualitas tamatan SMK Jurusan Teknik Sepeda Motor semakin baik dan dapat menurunkan TPT tamatan SMK.

Abstract

Peningkatan konsumsi bahan bakar fosil dan tingginya emisi kendaraan bermotor mendorong perlunya inovasi teknologi ramah lingkungan berbasis bioetanol dan sistem pembakaran modern. Penelitian ini bertujuan menganalisis pengaruh water–methanol injection (WMI) terhadap konsumsi bahan bakar, emisi gas buang, serta indikasi durability mesin pada sepeda motor Honda Beat FI 2019. Metode eksperimen digunakan dengan empat variasi perlakuan: standar, X2a (5% metanol), X2b (10% metanol), dan X2c (15% metanol), diuji pada 1500, 3500, dan 5500 RPM. Hasil menunjukkan bahwa variasi X2c memberikan efisiensi konsumsi tertinggi dengan penghematan hingga 13,04% pada 1500 RPM dan 11,11% pada 5500 RPM. Sementara itu, variasi X2a paling efektif menekan emisi CO dan HC, masing-masing 63,16% dan 32,45% pada 5500 RPM. Penurunan deposit karbon memperkuat temuan bahwa kombinasi teknologi WMI, ECU programmable, dan busi iridium berpotensi meningkatkan efisiensi energi sekaligus memperpanjang umur mesin. The increasing consumption of fossil fuels and vehicle emissions highlights the need for eco-friendly innovations such as bioethanol and advanced combustion systems. This study aims to analyze the effect of water–methanol injection (WMI) on fuel consumption, exhaust emissions, and indications of engine durability in a 2019 Honda Beat FI motorcycle. An experimental method was applied with four variations: standard, X2a (5% methanol), X2b (10% methanol), and X2c (15% methanol), tested at 1500, 3500, and 5500 RPM. Results indicated that X2c achieved the highest efficiency with fuel savings of 13.04% at 1500 RPM and 11.11% at 5500 RPM. Meanwhile, X2a was the most effective in reducing CO and HC emissions, with reductions of 63.16% and 32.45% at 5500 RPM. The reduction in carbon deposits further demonstrates that combining WMI with a programmable ECU and iridium spark plug can improve energy efficiency and extend engine lifespan.
