Abstract

The high level of air pollution is partly triggered by emissions from fossil-fuel-powered vehicles. Therefore, the presence of environmentally friendly vehicles is greatly needed. On the other hand, the availability of conventional vehicles cannot be immediately eliminated. One alternative is to convert conventional vehicles into electric vehicles. This study aims to assess and implement the process of converting conventional motorcycles into electric motorcycles as a more environmentally friendly transportation solution. The main components used are several parts from conventional motorcycles, a BLDC electric motor as the main drive, an electronic control unit, and a LiFePO4 battery as the energy source. The study was conducted using the R&D method. The result of the study is the creation of a converted electric motorcycle with a 3KW BLDC hub motor and a 48V 15 Ah LiFePO4 battery, with an average range of 30 km per full battery charge and a maximum speed of 56.7 km/h. Tingginya polusi udara salah satunya dipicu oleh emisi gas buang kendaraan berbahan bakar fosil. Oleh karenanya kehadiran akan kendaraan yang ramah lingkungan sangat dibutuhkan. Di lain sisi, ketersediaan kendaraan konvensional tidak bisa langsung dihilangkan. Salasatu alternatifnya adalah melakukan konversi dari kendaraan konvensional menjadi kendaraan listrik. Penelitian ini bertujuan untuk mengkaji dan mengimplementasikan proses konversi sepeda motor konvensional menjadi sepeda motor listrik sebagai solusi transportasi yang lebih ramah lingkungan.

Abstract

This study presents a thermo-structural finite element analysis of a single-cylinder diesel piston using ANSYS, comparing three aluminum alloys: Al2618-T61, Al4032-T6, and Al6061-T6. A coupled simulation approach was applied, where steady-state thermal results were imported into static structural analysis. Realistic boundary conditions, including applied combustion pressure, symmetry constraints, and cylindrical pin supports, were implemented based on Yanmar TF55 engine geometry. Results indicate that Al6061-T6 experienced the highest deformation and stress, nearing its yield limit at elevated temperatures. In contrast, Al2618-T61 and Al4032-T6 maintained structural integrity, with lower stress and elastic deformation within safe limits. Al4032 demonstrated superior dimensional stability, while Al2618 exhibited better strength under thermal load. These findings validate the importance of coupled thermal-structural analysis and material selection in piston design. The proposed framework offers reliable guidance for developing more durable, thermally resilient pistons for modern diesel engines.

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

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).
