Abstract

Abstract: The right oil selection is critical in maintaining the performance of a motorcycle engine, given its role in lubrication, cooling, and reducing friction between components. This study aims to analyze the effect of semi-synthetic and full-synthetic oils on oil temperature, engine vibration, torque, and power on 4 Stroke 250 CC motorcycles to provide comprehensive information to motorcycle users about the types of oils that can optimize engine performance. The research method uses an experimental approach with a Kawasaki Ninja 250 RR Mono motorcycle as the object of study. The test was carried out at various engine revolutions (RPM) by measuring vibration using a vibration meter, temperature with a thermocouple, and torque and power through a dyno test. Data analysis uses descriptive statistics to determine significant differences between oils. The study results show that full-synthetic oil consistently provides more optimal engine performance than semi-synthetic oil. Full-synthetic produces lower vibration, maintains stable temperatures, and produces higher torque and power at each RPM. These findings indicate that full-synthetic oils can improve engine efficiency, reduce the risk of damage, and extend the life of motorcycles.Keywords: Semi-synthetic Oil, Full-synthetic Oil, Engine Vibration, Oil Temperature, Engine Performance.

Abstract

Air pollution in urban areas is a multidimensional threat with systemic impacts on the environment and public health. Carbon monoxide (CO), as a toxic gaseous pollutant from the incomplete combustion of fossil fuels, is the focus of this study which evaluates the spatial-temporal distribution of CO concentrations in public spaces of Padang City during 2020-2024. Using a Systematic Literature Review (SLR) approach and longitudinal environmental data from four strategic points, a significant decrease in CO levels was found from 14,596 µg/m³ (2020) to 286 µg/m³ (2024). Peak concentrations occurred in the dry season, reinforcing the influence of meteorological variables. These results emphasize the importance of real-time digital monitoring systems, multi-sectoral emission policy reformulation, and integration of green open spaces in urban planning. In the future, monitoring should be expanded to other pollutants, congestion locations, and linked to public health early warning systems to support urban sustainability and resilience.
