Abstract

Adding too many electrical components to a vehicle can cause a lack of electrical energy. To overcome this, the capacity of the charging system needs to be improved. One method is by changing the diameter and number of turns of the copper wire in the stator coil. This study tested various combinations of wire diameter and turns to examine their effects on the voltage and temperature produced by the stator coil. The test used wire diameters of 0.7 mm, 0.9 mm, and 1.1 mm, with 50, 60, and 70 turns, at a constant engine speed of 3000 RPM for 5 minutes. The lowest voltage was recorded with a 0.7 mm diameter and 50 turns 26.5 V at the start and 25.7 V at the end. The highest voltage came from the 1.1 mm diameter with 70 turns 51 V at the start and 48.6 V at the end. The starting temperature for all variations was 36 °C. The lowest end temperature was 47.3 °C (0.7 mm, 50 turns), and the highest was 48.8 °C (1.1 mm, 70 turns). The results show that increasing both diameter and the number of turns raises voltage output, while temperature also increases slightly.

Abstract

3D printing technology is rapidly developing and being used in various fields. One of the main factors affecting print quality is the filament, with ABS being a popular material due to its eco-friendliness, ease of printing, and good mechanical strength. To achieve precision, the filament diameter must be consistent, around 1.75 mm or 2.85 mm according to the design nozzle diameter. The production of ABS filament uses a single screw plastic extruder machine, where the material is melted, extruded, and then cooled. Two main factors that affect the final dimensions are the extrusion temperature and the cooling medium. Improper temperature can alter the viscosity of ABS melt, affecting the extrusion rate and diameter accuracy. Meanwhile, differences in cooling media, such as blower air and water, affect material shrinkage and dimensional stability. This research aims to analyze the influence of extrusion temperature variations and cooling media on the diameter of ABS filaments. Through experiments with varying parameters, the pattern of diameter changes will be analyzed to determine the optimal conditions that minimize dimensional deviations. The research results are expected to contribute to the optimization of ABS filament extrusion parameters to support the 3D printing industry with higher quality materials.

Abstract

The rapid growth of motor vehicles, exceeding 169 million units in Indonesia by 2025, highlights the urgent need for energy-efficient and environmentally friendly transportation solutions, such as hybrid vehicles. Brushless Direct Current (BLDC) motors are crucial components in these systems due to their high efficiency and compact design, particularly when directly integrated into wheels. This study specifically aims to analyze the impact of varying loads on the power consumption of a BLDC motor within a front-wheel-drive hybrid motorcycle prototype equipped with a Continuously Variable Transmission (CVT) system. Experimental data was collected using a wattmeter on a prototype subjected to different passenger loads: 55 kg, 75 kg, and 100 kg, at constant speeds of 20 and 40 km/h. The findings consistently show that an increase in load significantly and positively correlates with higher power consumption of the BLDC motor. For instance, at 40 km/h, power consumption for a 100 kg load reached 729.578 Watt, whereas for a 55 kg load it was 649.605 Watt. This demonstrates that greater effort (power) is required from the motor to overcome the inertia and increased resistance associated with heavier loads. These results contribute to optimizing energy efficiency in hybrid vehicle design and underscore the importance of load management for sustainable transportation.

Abstract

Engine overheating is a critical condition that can cause damage to internal components, reduce operational efficiency, and lead to overall system failure. The absence of an automatic protection system is one of the primary factors contributing to damage. This study aims to design and test a temperature sensor-based safety device that can automatically cut off the engine's working system when the temperature exceeds the safe limit. The method used is descriptive statistical analysis to evaluate the effect of independent variables (operational time duration and workload) on the dependent variable (coolant temperature). The system was tested through water heating simulation using an electric heater and controlled by an Arduino Nano microcontroller, a MAX6675 temperature sensor. Testing was carried out with variations in power load (150, 300, 450, 600, and 750 Watts) and operational duration (20, 40, and 60 minutes). Temperature data were collected and analyzed using ANOVA to determine the effect of load and time on temperature increase. The results showed that the temperature increased significantly with increasing power load, with temperatures approaching 100°C at loads ≥450 Watts in less than 20 minutes. The load variable shows a significant effect on temperature (p < 0.05), while the duration of time shows a nonlinear but not statistically significant upward trend. The safety device is proven to be able to automatically disconnect the system when the temperature reaches the specified maximum limit, thus effectively preventing engine damage due to overheating.

Abstract

The development of construction materials is currently very rapid, including in the manufacture of fishing boats that still use wood. As an alternative, High Density Polyethylene (HDPE) plastic can replace wood because of its various advantages. The process of making fishing boats uses the plastic welding method, where the material is heated close to the melting temperature with a welding gun. The welding rod melts due to heat and is pressed continuously while the welding gun moves backward. This study aims to determine the effect of variations in the hot gas welding process on mechanical tests, especially bending tests on plastic welding joints. The two independent variables used are the hot gun temperature (250°C, 300°C, and 350°C) and the V bevel angle (60°, 75°, and 90°). The five controlled variables include the anvil temperature of 150°C, 3,2 mm thick HDPE plastic sheet, hot gas speed welding method, 5 mm diameter HDPE plastic additives, 7 liters/minute air flow rate, 1.2 mm/s welding speed, and 2 mm root gap. The research results are expected to obtain the maximum value of the bending test strength from the interaction of hot gun temperature variations and V-beam angles, as well as being a reference in making fishing boat bodies from HDPE using the hot gas welding method.

Abstract

Flywheel is an important element in the motor starter system due to its ability to store relase kinetic energy during the rotation process. This study aims to evaluate the effect of rotation speed variation and flywheel geometry shape on the kinetic energy produced, assuming the flywheel mass is fixed. The analysis is conducted through theoretical approach and numerical simulation using the rotational kinetic energy equation, with I as the moment of inertia that depends on the geometry shape,and as the angular velocity and shape of  the flywheel. The results show that the geometry shape greatly affects the moment of inertia, and at the same angular velocity, the flywheel with larger moment of inertia is able to store more kinetic energy. The conclusion of this study provides recommendations in the selection of the optimal flywheel design to improve the efficiency of the motor starter system.
