Abstract

An electric car is a vehicle that is driven by an electric motor, the electric motor obtains power from electricity stored in the battery. Chassis is an important component in electric cars. Chassis is part of an electric car that functions as a support system in an electric car. In the chassis there is a maximum and minimum stress called the principal stress. This principal stress becomes a reference to determine the safety of the chassis. So it is necessary to know the principal stress on the chassis. The testing process uses two drivers, each of which weighs 45 kg and 56 kg. The tests were carried out at three different points on the electric car chassis. From the results of the principal stress test, σ1 = 3.3282 MPa and σ2 = 1.5429 MPa for the 45 kg driver and σ1 = 3.8233 MPa and σ2 = 2.1123 MPa for the 56 kg driver. The principal stress on the chassis is still in a safe condition because it does not exceed the yield stress of the chassis material.

Abstract

Nanoparticles are particles that have a size of nm and a size range of 1-100 nano. These particles are formed by the DC Thermal Plasma method. This study utilizes a 70 ampere DC Plasma cutting machine as a plasma flame. The combustion process is carried out in a reactor tube, and the material processed is Aluminum powder (Al) with a purity of 92.5%. The input mass of Aluminum powder is injected at 5gram. Burning process (15 seconds). The particles attached to the reactor wall are sucked in with the help of a vacuum pump then collected on the filter tube. The material is measured by mass using a digital scale. Analysis of the data used is using the Taguci L27 method. The parameters used in this study are injection angle with 3 variations (45 °, 60 °, 90 °) and fire length with 3 variations (2.31 cm; 3.87 cm; 4.28 cm). The contribution of machining parameters in the manufacture of alumina nanoparticles is significant, namely the injection angle parameter has a contribution of 37% and a fire length parameter of 4.2%. The results of the study are generally influenced by the injection angle. The optimum injection angle is 45 ° with an average of 3.56 grams and the least productivity is the injection angle parameter 90 ° which is equal to 2.17 grams The conclusion of the study is that the greater the material injection bend angle the less productivity of DC Thermal Plasma devices as well vice versa.

Abstract

The need for energy every year both in the domestic and global increases. Indonesia's energy needs are predicted to increase by 5% each year. Indonesia has renewable energy potential from solar, hydropower, wind, and geothermal sources. The potential of new renewable energy amounted to 442 GW. Of the 442 GW, the greatest potential is owned by 207 GW of solar energy. The high potential of solar energy in Indonesia is because Indonesia is located in the tropics which experiences sunshine time of approximately 6-8 hours per day and the sun continues to shine throughout the year. However, the length of irradiation also has an impact on increasing the temperature of solar panels. The higher the temperature of the solar panel, the output power will decrease and the life of the solar panel is reduced. The use of passive cooling from reference has a lower efficiency increase than active cooling. However, its installation requires lower costs, minimal maintenance, and no additional power requirements. This research will use 20WP monocrystalline solar panels with three cooling variations, namely: 1) with the addition of a thin aluminum plate and Vortex generator 2) By giving a tub of water under the panel 3) the Addition of aluminum fin. The three variations are compared with solar panels without cooling. The results on the first day showed a decrease in temperature of 2.30C with aluminum fin and an increase in power of 6.97% when using a water container. On the second day, a temperature decrease of 2.90C and a power increase of 5.81% when using aluminum fin coolers were recorded.
