    Intense braking can cause heat accumulation that can reduce the braking system’s efficiency and damage the braking system components due to changes in material structure. The high temperature in the braking system of heavy vehicles requires an air-cooling system that produces high-pressure air. This study compares the cooling process results between natural air and forced air. CFD modeling was chosen as the method to simulate the cooling process of bus drum brakes. The CFD method works by involving a network of elements in a system called a mesh. In CFD, the mesh is a component that focuses on dividing the fluid domain into small elements to analyze fluid flow, heat transfer, and dynamic phenomena. Using a cooling process, the brake system temperature gradually decreased as the wind speed increased. The examination proved that natural air could reach the highest temperature of 168.73 °C and the lowest temperature of 63.01 °C. Meanwhile, forced air could reach the highest temperature of 73.8 °C and the lowest temperature of 30.73 °C. Statistical models and machine learning were carried out to predict the accuracy of simulation from SOLIDWORKS. The values of average temperature after the cooling process are examined by employing the Gradient Boosting algorithm with the highest accuracy of prediction (R2) value of 0.999895 in natural conditions and 0.999822 in forced conditions. Overall, forced air shows better temperature reduction than natural air. By lowering the operating temperature, drum brake systems can extend their lifespan.

    Hybridization on a motorcycle is a condition of utilizing an electric motor as an additional powertrain. Motorcycle hybridization needs to consider the topology used, specifications of the internal combustion engine (ICE), electric motor (EM), and battery capacity. This paper focuses on the hybridization mechanism using the P1 topology and considering 3 basic components. The P1 topology design is commonly used on conventional motorcycles. The use of the P1 topology makes the EM a torque assist when the engine accelerates. The ICE used is a single cylinder with a capacity of 125cc, the EM uses a BLDC type motor with a power of 250W, and the battery is described with a voltage of 51.8V with 5 capacity variations such as 6.8, 9.6, 12.8, 16.0, and 19.2 Ah. Motorcycle dynamics tests use 3 Driving Cycle models, such as ECE-R15, ECE-R40, and WMTC. The achievement of this analysis is the determination of battery capacity with a deep of discharge (DoD) of less than 70%. The results show that when testing on the ECE-R15 Driving Cycle, using a 6.8 Ah battery is effective with a DoD of 11.911%. The reduction in fuel consumption reaches 6.891%. Testing on the ECE-R40 Driving Cycle, a 9.6 Ah battery is more effective with a DoD of 50.181%. The reduction in fuel consumption reaches 1.853%. Testing on the ECE-R40 Driving Cycle, a 9.6 Ah battery is more effective with a DoD of 69.795%. The reduction in fuel consumption reaches 0.863%. In 3 Driving Cycle tests, the use of a 3P battery is more efficient because during testing, the DoD value is not more than 70%.

    Universidad de Antioquia
    A vehicle is more stable when the geometric center, center of gravity, and stagnation point are in line. However, the inflow direction and velocity magnitude of the operational environment of road vehicles are varying. This study aims to investigate the aerodynamic behavior of a water-drop-shaped vehicle under side wind conditions. Some essential aerodynamic performances of the vehicle are numerically and graphically analyzed at 0 deg, 10 deg, and 20 deg of side wind directions. The value of the coefficient of drag, drag force, coefficient of lift, and lift force exponentially increases as the yaw angle elevates. The lower part on the area of the front-wheel compartment becomes the critical location indicated by the results on pressure coefficient, friction coefficient, and total wall shear stress distribution along the vehicle surface. Increasing the side wind angle triggers more significant vortex regions generated around the wheel compartment and on the leeward side of the vehicle.

    Z. Arifin, I W Adiyasa, and M A Hizami Rasid
    IOP Publishing
    Abstract Optimal design results in maximum motor performance. This type of BLDC motor has undergone design innovations such as surface-mounted permanent magnet (SPM) with variants such as: radial magnet, rectangular magnet, and bread-loaf. The position of the outer rotor is a motor design that is commonly applied to electric bicycles. The position of the magnet attached to the side of the electric motor body allows for superior torque performance. In this paper, we present an analysis of the BLDC motor on an electric bicycle that has been implemented. The motor used uses the outer rotor SPM geometry with a power of 500W. Parameter changes made are slot depth, tooth width, and comparing the basic design with the Halbach array design using 2 and 3 magnets. Changes in these parameters have an impact on power, torque, speed, and efficiency.

  • Analysis of the potential of renewable energy in fulfilling home electrical loads and charging systems for electric motorcycles in Yogyakarta
    I W Adiyasa, F D Wijaya, and R P Suteja
    IOP Publishing
    Abstract The implementation of renewable energy sources such as photovoltaic (PV) and wind turbine (WT) is widely applied. Indonesia is a country located in the tropics, with the potential for renewable energy sources such as solar and wind. The number of potential sources of renewable energy has an impact on the amount of energy that can be produced using PV and WT. Data on potential renewable energy sources is obtained from the NASA Prediction of Worldwide Energy Resource (POWER) database and is used for analysis of electrical energy that can be produced. The PV and WT power plants used in this analysis use a power range of 600 - 1200 Wp for PV and 1 - 3 kW for WT. The electrical energy that has been produced will be stored in energy storage in the form of a battery with a capacity of 1 kWh. The test analysis uses 6 scenarios of the number of PV, WT and batteries using a house load and charging an electric motorcycle.

  • Aerodynamic performance analysis of open-wheel vehicle: Investigation of wings installation under different speeds
    A Yudianto, H A Susanto, A Suyanto, I W Adiyasa, A Yudantoko, and N A Fauzi
    IOP Publishing
    Abstract An open-wheel vehicle with manual hybrid engine control with formula-like body shape was developed for a learning media at a vocational high school. This study aims to analyze the airflow of over the vehicle body as the effect of wing installation under various vehicle speeds. The investigations are to observe and evaluate the drag coefficient, drag force, lift coefficient, downforce, pressure distribution, streamlines, and velocity vector condition by emphasizing on the results from Computational Fluid Dynamics (CFD) simulation. The study found that installing the front and rear wings contribute to the decrement of drag coefficient 0.07 points and keeping the drag force relatively constant since the projection area changed. The benefit of having wings installed significantly increases the downforce by 334 N, which is 5.51 times higher than without wings in the speed of 150 km/h. However, the engine cover gives a significant obstacle to airflow, reducing the functionality of the rear wing. As such, the presence of the rear wing does not have a substantial effect on reducing the wake region.

    IOP Publishing
    Abstract Modification of a motorcycle helmet has been performed by inserting an electronic device in the helmet’s inner liner. Therefore, a hole requires to be made to place the device. This study aims to analyze the impact loading performance of a motorcycle helmet due to an impact from the top, rear, and side. The investigation of stress distribution and acceleration experienced by the helmet is analyzed by utilizing finite element method simulation. The results indicate that the hole position is not in the impact area. The outer shell experiences higher stress than the inner liner in all testing conditions. The rear impact causes the highest value of the outer shell stress, where for the inner liner, the side impact contributes to the maximum value of the stress. Headform linear acceleration reaches the peak than is higher than the basic requirements of the helmet testing standard.

    IOP Publishing
    Abstract The stiffness of the car body becomes important due to the fact that it must keep the passenger’s compartment undeformed even during severe operating conditions. Car body T-joint is one of the main parts of car’s body to properly support its function. Three different cases were applied to evaluate the influence of difference spot weld configuration to bending and torsional stiffness of car body T-joint. The stresses and the displacements were also deeply investigated. The maximum stress in longitudinal direction and due to moment reaches its peak on 55x15 spot weld configuration. The displacement increases as the spot weld distance widen. Both bending and torsional stiffness decrease as the spot weld distance becomes larger.

    Sutiman, I W Adiyasa, A Prayoga, A G Irfak, and R S Ardiyan
    IOP Publishing
    Abstract The use of an electronic system to regulate the injection system is a solution that can improve the performance and fuel efficiency of an engine. However, conventional vehicles require retrofit to be able to use the electronic fuel injection (EFI) system. The design uses a microcontroller system with ARM32 architecture. The inputs used to determine the duration and timing of the injection are a crankshaft position sensor (CKP), throttle position sensor (TPS), manifold absolute pressure (MAP), air temperature sensor (ATS), and lambda sensor. Before the sensor signal enters the microcontroller, the signal is filtered using a low pass filter (LPF) with a cut-off point of 50Hz. The actuator system consists of an injector. While the ignition system can use a capacitor discharge ignition (CDI). The novelty in this design is that the type of sensor can be replaced with a resistant type sensor. So that there will be many variants of the fuel injection system tuning retrofit that can be done with conventional motors.

    IOP Publishing
    Abstract Virtual reality technology has been adopted as a modern learning media in vocational education. Nowadays, the practical learning needs complete equipment and tools to achieve the goal study. However, the conventional media requirement is a challenge for academician for learning process, specifically in automotive and machine areas. Virtual reality provides a solution for this problem, but still needs proper analysis on the impact of usability between conventional and VR media to which each learning objective is achieved. The case study used in this research is a two-stroke engine, which is currently a rare item in the real world. We replicated this two-stroke engine in the developed VR system using Unity game engine and Oculus quest. A comparison on the usability effectiveness on conventional and virtual reality methods was conducted using cognitive walkthrough, which follows the four steps of learning objective training. The result shows that three out of four learning objectives are similar with conventional objective training. One of the process on preparation for disassembly machine has slight difference with conventional training; faulty engine due from environment elements (liquid, rusty iron) was not included.

    IEEE
    The location of the plant depends on the potential of renewable energy sources. This microgrid power source is a renewable energy generator that will be optimized. The mobile power plant in which implemented is a synchronous generator coupled with a diesel engine, and two power plants based on an induction generator which is implemented as a wind power plant and a micro hydropower plant. Generator will be operated in stand-alone and parallel in the system when the load increases, the load decreases. The increase in load and decrease in the burden can be influenced in terms of the location of these renewable energy plants and can cause a decrease in voltage and frequency. To support the benefits of the scattered power plant, good planning is needed, including determining the location of placement and the power of the scattered power plant that is used so that by optimizing the location of the power plant system in order to achieve optimal operating patterns, when the system voltage stability can reach the voltage parameter 380 V (+ 5% and -10%) and 50 Hz (± 1%) frequency when the generator is working in parallel with variations in loading. Voltage reduction can be minimized by choosing the cable type and generator distance.

  • Applied programmable ECU on an internal combustion engine single cylinder 600 cc for Student Formula Japan
    I Wayan Adiyasa, Aan Yudianto, Ninda Kurniadi, and Sutiman
    IOP Publishing
    Abstract Student formula competition requires modification of the intake manifold hole by 20 mm. The internal combustion engine used has a capacity of 600 cc and an intake hole of 45 mm. The intake hole reduction affects the performance of the internal combustion engine. The ratio of the amount of air that is too small causes a decrease in engine performance. Ignition remapping is needed and fuel injection on the internal combustion engine. In the remapping process, the ratio of air and fuel is adjusted to the needs. The standard ECU on an internal combustion engine cannot be remapped. So the standard ECU on internal combustion engines is replaced using Motec M400. The parameters on the engine are only added to the camshaft sensor to determine the ignition timing and injection. Other sensors such as throttle position sensor, manifold absolute pressure, intake air temperature sensor, and engine temperature are used to determine ignition mapping parameters, fuel injection, and compensation for cranking, idle, and acceleration requirements. Tests obtained ignition remapping and fuel injection on internal combustion engines using ECU.

  • The Effect of Masses in the Determination of Optimal Suspension Damping Coefficient
    A Yudianto, N Kurniadi, I Wayan Adiyasa, and Z Arifin
    IOP Publishing
    Abstract The proper design of the suspension damper determines the ride quality and road holding performance of the suspension system against the road excitation. The objective of the present study is to investigate the effect of both sprung and unsprung masses on the root-mean-square vertical acceleration experienced by the occupants to determine the optimal value of the damping coefficient. Road excitation, 2-DOF mathematical model, and ISO 2631 weighting function were numerically modelled into three different cases in Matlab platform. The responses in root-mean-square value of acceleration were then evaluated. Further, the results were compared and the analysis was performed to determine the optimal value of the damping coefficient for the proposed suspension model. The obtained results indicate that varying the sprung masses with the proportional value of unsprung masses does not affect the root-mean-square value, but it increases the value of optimum damping coefficient by 131.5 Ns/m. Making the sprung mass constant increases the root-mean-square value by 0.005 m/s2 for each chosen unsprung mass. However, fixing the unsprung mass influences both acceleration and the value of damping coefficient.
