Abstract

In the welding process it will produce excessive heat and in the slow cooling process it will form chromium carbide which precipitates on the grain. These deposits can cause a decrease in the physical and mechanical properties of a material. This research aims to determine the effect of tensile strength and hardness of material resulting from GTAW welding on ST 45 Steel on variations in cooling media. The research method used is quantitative experimental, where the specimens are welded and cooled with three cooling media, then tested for tensile and Vickers hardness to evaluate their mechanical properties. The results showed that the SAE 20 W-50 oil cooling media produced the highest Modulus Young value (average 1584.60 MPa) and the highest Vickers hardness (459.33 HVN), while air provided a higher Yield Strenght (368.72 MPa). Statistical analysis using ANOVA confirmed that the differences were statistically significant. The conclusion of this research shows that SAE 20 W-50 oil is most effective in increasing material hardness and stiffness, while air is superior in increasing tensile strength.

Abstract

Finding the appropriate thickness for the trash can. Will use the 3d printer method to make specimens and carried out by experimental methods that require several specimens to be tensile tested and the planned result is to find a strong thickness by knowing what thickness and layer will be used next. This research was conducted at the workshop of the Polytechnic of the State of Malang, there needs to be an innovation where the author makes several experiments  with  a  thickness  of  3  mm,  4  mm  and  the  last  one  is  5  mm  with  a  layer combination of 0.1 mm, 0. 2 mm and 0.3 mm to find out at what thickness and using what layer we should use, When we have found the thickness and what layer we should use we can make another trash can using 3d printing, and in using 3d printing parameters we must use 100% infill, From the results of data analysis using statistical software shows that the p-value is 0.000 with α of 0.05 which means the p-value ˂ α, then H0 is rejected and H1 is accepted.

Abstract

The significant increase in motorcycle production in August 2024 has reached 137,350,299, but there are still several obstacles that cause less than optimal engine performance. The study aims to analyze the effect of variations in the number of injector holes on power in a 110cc motorcycle. The approach used is a quantitative experimental type to reveal the effectiveness of using variations in the number of injector holes on power in a 110cc motorcycle engine. The sample used is a 110cc motorcycle, which is affected by four variations in the number of injector holes 4, 6, 8, 10. The results of the study show that the highest power of 6.43 HP and 7.80 Nm is obtained from hole 4 using RON 95 fuel, meaning that H0 is rejected and H1 is accepted, meaning there is a significant influence between the number of injector holes and the type of fuel on the power of a 110cc motorcycle.

Abstract

The modification of the dredger ladder at Perum Jasa Tirta I Workshop in Kediri has so far only involved an increase in length, without any changes to the shape or design model. The objective of this study is to analyze the influence of joint angle and material selection on the structural strength of the dredger ladder. The research method involves Finite Element Analysis (FEA) simulations using SolidWorks and ANSYS software to test variations in joint angles—30°, 45°, and 60°—and two types of steel materials: SS400 and ASTM A36. The simulation results show that the variation in angle affects the von Mises stress, with values of 278.16 MPa for SS400 and 271.21 MPa for ASTM A36. SS400 material has a higher safety factor, making it safer for ladder applications, although ASTM A36 also demonstrates better performance in terms of dynamic resistance. Overall, the combination of a 30° angle and SS400 material yields the best structural strength analysis results compared to other combinations.

Abstract

PT KAI (Persero) requested PT INKA (Persero) to increase the operational speed of passenger trains from 120 km/h to 160 km/h to enhance efficiency and meet mass transportation demands. A key component affecting stability is the yaw damper bracket, which absorbs lateral vibrations between the bogie and carbody. This study analyzes and optimizes the bracket’s structural strength using FEA in ANSYS Workbench. The material used is SM490A steel, chosen for its high yield strength and deformation resistance. Two models were evaluated: the initial design and a topology-optimized design. Results show the bracket’s mass was reduced from 13.36 kg to 9.61 kg, improving weight efficiency by 28%. Although stress increased from 124.12 MPa to 145.05 MPa, the final design maintains a safety factor of 2.2405, remaining within safe limits. The optimized bracket is suitable for use in high-speed train structures.

Abstract

Motorcycles are the most widely used vehicles in Indonesia due to their practicality, especially those with automatic transmissions. However, the increasing number of motorcycles, particularly in East Java Province, has contributed significantly to air pollution through exhaust gas emissions. This study aims to analyze the effect of injector hole variation and fuel octane rating (RON) on exhaust emissions and in 110cc gasoline motorcycles. The method involves laboratory testing with injector hole variations (4, 6, 8, 10) and the use of Shell RON 92 and RON 95 fuels. The observed variables include exhaust emissions (CO and HC) and specific fuel consumption, with engine temperature controlled at 80–85°C and fuel pressure at 43 psi. The results show that the configuration of a 6-hole injector with RON 95 produces the lowest emission values, with CO at 0.02% and HC at 84 ppm, meeting the Indonesian Ministry of Environment and Forestry’s emission standards (CO ≤ 3%, HC ≤ 1000 ppm), while also achieving the most efficient fuel consumption across all RPM ranges.

Abstract

This study analyzes the maintenance of the CY-K510N CNC machine at PT Wilis Indonesia Steel using the Reliability Centered Maintenance (RCM) method. The main issue identified is high downtime, primarily caused by repeated failures of the servo motor, which recorded 15 breakdowns and a total downtime of 218 hours in 2023. The RCM approach was chosen because it can identify critical components and develop maintenance strategies based on function and failure risk, unlike conventional preventive methods that rely only on fixed schedules. The Failure Mode and Effect Analysis (FMEA) results show that the servo motor and gear spindle are the most critical components with the highest risk values. Implementing the RCM strategy is recommended to improve machine reliability, reduce breakdown frequency, and enhance overall productivity.

Abstract

Aluminum 6061 is susceptible to corrosion in aggressive environments despite its natural corrosion resistance. Anodizing effectively improves corrosion resistance and hardness; however, the effect of voltage variation requires further analysis. Research using voltages of 9V, 10V, 11V, and 12V showed that 10V resulted in the lowest corrosion current (1.456 × 10⁻⁸ A) and the highest polarization resistance 7,1474 × 10⁶, indicating optimal corrosion resistance. Hardness increased with voltage, reaching 49 HB at 12V. Voltage variation had a significant effect, with 10V being optimal for corrosion resistance and 12V for maximum hardness. This research are relevant for industries requiring a combination of high corrosion resistance and mechanical strength.

Abstract

The study aims to analyze how variations in wheel rotation speed and disc pad geometry affect brake pad temperature. During the braking process, heat is generated due to friction. If not managed properly, this heat can diminish braking performance and accelerate brake pad wear.Tests were conducted at four different motor rotation speeds: 1000 RPM, 1500 RPM, 2000 RPM, and 2500 RPM. The test system was designed using a braking system demonstration tool equipped with speed sensors and temperature sensors. This setup was connected to an Arduino microcontroller, allowing real-time data to be displayed via a Graphical User Interface (GUI) in MATLAB.The results indicated that both brake pad geometry and wheel rotation speed significantly impact temperature. Standard brake pads displayed the highest temperature at 2500 RPM, reaching 63.33°C. In contrast, brake pads with holes demonstrated superior performance, producing the lowest temperature of only 43.00°C. As the wheel's rotational speed increased, the temperature on standard pads rose from 36.67°C at 1000 RPM to 63.33°C at 2500 RPM. This indicates that RPM is a primary factor in heat generation due to friction. The MATLAB GUI effectively visualized the relationship between RPM and temperature, facilitating the analysis and evaluation of the data.
