Abstract

The electric vehicle is a vehicle with a driving source of an electric motor, requiring a battery for the stored energy. Battery packs are widely used as energy storage for electric vehicles. The battery pack is a series of several small batteries arranged in series and parallel so that they have an output voltage and capacity as required. 18650 Lithium battery is the most widely used to make battery packs and used on electric motorcycles. a 18650 Lithium battery has an output voltage of 3.7 V with various capacities such as 1500 mAh, 2000 mAh, 3000 mAh, etc. To design a 48 V 50 Ah battery pack requires a series of 18650 3.7 V 3000 mAh batteries which are arranged 13 pieces in series and 19 pieces in parallel. Before assembling, each 18650 battery must be checked for voltage, the voltage in each 18650 battery must be in the range of 3 ”“ 4.2 V. If it is less than 3 V then it needs to be recharged, if it is less than 2 V then the battery condition is not good. The battery pack discharging test is carried out by loading a BLDC 2000W 48V electric motor until the battery pack voltage drops to 39 V. The discharging process lasts for 13 hours with an average current of 3.5 A. From the test results, the battery pack capacity can be calculated, namely 45.5 Ah.

Abstract

The suspension must provide comfort and safety to the vehicle. Therefore, it is necessary to analyze the load's effect on the pressure distribution on the axle so that the spring strength from the sideload force can be simulated. This study aims to analyze the sideload force of type C suspension springs using FEM. Spring variations are the number of different threaded coils, namely 11, 12, and 13. In the FEM simulation, the spring is given a load until 50mm, 100mm, 150mm, 200mm, and 250mm displacement occurs. The loading spreads to the X, Y, and Z axes. Each direction of the axis is measured by the pressure that occurs. The results showed that the pressure values that occur on the X, Y, and Z axes decreased with each increase in the number of screw coils. The lowest X-axis pressure reduction occurs in thread 12 at 63%. Meanwhile, the pressure on the Y axis decreased by 27% on the spring screw 12. The highest decrease in pressure on the Z axis occurred by 34% on the spring screw 12 compared to the spring screw 11.

Abstract

Indonesia is one of the countries that uses the most motorized vehicles, which increases air pollution and fuel crises. Using biofuel is one solution to overcome this problem. Methanol is used as a mixture of Pertamax to produce environmentally friendly and renewable biofuel. This is because methanol has high octane and oxygen. Mixing methanol in Pertamax was carried out to analyze the impact of Torque, Power, and Exhaust Gas Temperature (EGT) of a 150cc petrol engine. Methanol 5%, 10%, and 15% was mixed into Pertamax with engine speed variations of 1000, 2000 and 3000 rpm. Dynotest is used to measure engine performance and thermocouples to measure EGT. Test results show the highest increase in engine torque and power of up to 25% at a speed of 2000 rpm with the PM15 mixture compared to P100. The highest reduction in EGT value occurred when using the PM15 mixture at a speed of 1000 rpm up to 28% compared to P100. This shows that the addition of methanol to Pertamax increases torque and power and reduces the EGT of the gasoline engine.

Abstract

Badminton is a popular sport in the world, especially in countries such as Indonesia, Malaysia, China and many European countries. One of the important elements in badminton is the shuttlecock, which is used as a game ball. The shape density of feather shuttlecocks or synthetic shuttlecocks also affects the movement of the shuttlecock and produces different drag force values. Several methods can be used to test the balance of a shuttlecock, such as a method of throwing it vertically, the method of hitting it manually or using a throwing machine. Both methods show the movement of the shuttlecock directly so that it can be seen whether its movement is balanced or unbalanced, but this method requires a fairly large area. A simpler method is to use a shuttlecock balancing tester (SBT), but the current equipment is noisy and has quite large dimensions so it is not practical. This research aims to develop an existing SBT with less noise, smaller sizes, and more practicality by using a 120 mm cooling fan. The study was carried out to determine the required air flow speed and the correct size of the honeycomb hole. The results of the research show that the airflow speed required in the SBT so that the shuttlecock lifts per floats and rotates stably is 5.0 m/s using a honeycomb hole with a diameter of 6 mm and 4.6 m/s using a honeycomb hole with a diameter of 8 mm . Using 8 mm honeycomb produces air flow with a greater lifting force than using 6 mm honeycomb.
