Abstract

This study aims to analyze the effect of variations in fuel brands, spark plug types, and tire pressure on four-stroke motorcycle engine performance. The independent variables tested include three variations of fuel brands (Pertamax, Shell Power, and AKR 92), spark plug types (standard, iridium, and platinum), and tire pressure (28 psi, 33 psi, and 38 psi). The experimental method was conducted on a Honda MegaPro PGM-FI motorcycle by measuring torque and power at various RPM using a chassis dynamometer test equipment. The results show that the sample 2 with combination of Shell-Super fuel brand, platinum spark plugs, and 33 psi tire pressure has a significant positive impact on engine performance, with higher torque and power as well as more consistent variations than other combinations. This research has important implications for motorcycle users, enabling them to optimize vehicle performance by choosing the right fuel, keeping spark plugs in good condition, and maintaining optimal tire pressure.

Abstract

Through the Cooperative Learning type Group Investigation (CL-GI), this study seeks to improve students' communication abilities. The beginning ability was taken into account as a moderator variable in this quasi-experimental investigation, which was carried out using a 2x2 factorial design. The study's participants were LVE 1 and 2 students in the 10th grade at Vocational High School (VHS) YPM 8 Sidoarjo. After performing several preliminary tests, such as normality and homogeneity tests, a two-way ANOVA was used to analyze the data. Numerous inferences can be made in light of the findings and debate. First off, kids who learnt with CL-GI had much better communication abilities than those who learned with DI. Second, students with strong initial abilities had much better communication skills than students with poor initial abilities. Thirdly, there was no discernible connection between the learning model and students' starting points in terms of communication abilities in the basics of automotive engineering.

Abstract

The growth of motor vehicles in Indonesia, particularly motorcycles, is increasing rapidly. This rise contributes to environmental issues, especially noise pollution, which is caused by the disturbance from vehicle sounds. A catalytic converter, installed in vehicle exhaust systems, reduces harmful emissions but also affects noise levels. This study examines the impact of a nickel-coated copper catalytic converter on motorcycle noise. The research is experimental, comparing the noise produced by a standard exhaust with two experimental exhaust systems fitted with catalytic converters. The study uses a Honda Astrea motorcycle, and noise testing follows the ISO/FDIS 5130 standard. The results are compared to Government Regulation Law No. 07 of 2009, which sets noise limits for motor vehicles. The research results show that the standard exhaust produces a noise level of 83.3 dBA, experiment 1 catalytic converter produces a noise level of 83.6 dBA, and experiment 2 catalytic converter produces a noise level of 82 dBA. From these results, it is evident that experiment 2 catalytic converter succeeded in reducing the noise level by 1.56% compared to the standard exhaust. However, all three types of exhausts still do not meet the quality standards set in the Minister of Environment Regulation No. 07 of 2009 regarding Noise Limits for New Motor Vehicle Types, which sets the maximum noise limit at 80 dBA for stage 1

Abstract

Drill bit failure in the drilling process often occurs due to exposure to mechanical, thermal, and chemical loads during operation. Nachi HSS drill bits, as critical components in the manufacturing industry, are prone to sudden wear and breakage due to dynamic processes involving material fragmentation, friction, and increased local temperatures. This study analyses the root cause of Nachi HSS drill bit failure through fracture investigation, chemical composition, and microstructure. The analysis methods include macroscopic testing to identify fracture patterns, optical microscopy to evaluate surface deformation, and X-ray Fluorescence (XRF) testing to verify material composition. The results showed that the fault was a brittle fracture due to a mismatch in chemical composition: molybdenum (Mo) levels were not detected. At the same time, chromium (Cr) and vanadium (V) only reached 3.85% and 0.95%, 0.45% lower than factory standards. This deficiency reduces resistance to thermomechanical loads, triggering stress concentration and rapid crack propagation during the drilling of ST37 steel material at a speed of 1,800 RPM. These findings emphasize the importance of quality control of material composition and optimization of operating parameters to prevent premature failure.

Abstract

Pollution air in cities in Indonesia, such as Jakarta, Tangerang, and Bandung, is especially caused by exhaust emissions from vehicle motorized, like carbon monoxide (CO) and hydrocarbons (HC), which originate from burning material burn the ones that don't perfect. Technological catalytic converters are used to reduce emissions, but converters made from metal have their own cost. This study evaluates exhaust Metallic Catalytic Converter (MCC) technology with alternative materials copper (Cu). The result shows that the MCC Cu exhaust system is significantly more effective in reducing CO and HC emissions compared with exhaust without the original equipment manufacturer (OEM) catalyst and exhaust. The average CO emissions are 2.13 %Vol and HC emissions are 198 ppmVol, lower compared to the second type of exhaust. Findings This shows that MCC Cu exhaust is not only more effective in reducing danger but is also more economical compared to catalytic converters made from metal noble, offering a solution sustainable and affordable for problem pollution air from vehicles.
