Abstract

Currently, the vehicles that are commonly used are vehicles with fossil fuels, but we all know that these fuels are non-renewable fuels and their availability in nature is very limited, so it is necessary to innovate to use other renewable energy sources. one of which is electrical energy. Besides that, the use of electrical energy for vehicles is currently very relevant because of its relatively high efficiency and friendly to the environment, namely no CO or CO2 gas is formed as in conventional vehicles. Indonesia has the potential to develop electric cars because there is a lot of nickel available to be processed into batteries. Thus, our country has a very large opportunity to produce electric cars. To realize this, it is deemed necessary to conduct a thorough study such as the level of comfort and safety. Thus, it is needed to conduct a study of the mechanical control system so that driving comfort and safety can be achieved. In this research, we will measure the turning radius of the vehicle at various TOE angles. The resulth of this study are the greater of TOE angle produce the higer the turning radius of the vehicle, The smallest turning radius is at a TOE angle 0 degrees which is 4.42 meters and the largest at a TOE angle 1.035 degrees which is 4.53 meters.

Abstract

The use of used cooking oil and waste oil as fuel—particularly for cooking—is becoming increasingly common among the public in Indonesia. While this practice offers economic advantages, improper management of used oil can lead to environmental problems such as air and soil pollution. To address this issue, alternative methods for processing used oil are needed to minimize its negative impact. One such method is the use of a used oil stove, which utilizes waste oil as fuel. This not only reduces the amount of oil discarded but also provides a cost-effective substitute for more expensive fuels like gas or kerosene. The purpose of this study was to examine the effect of varying air flow velocities on flame temperature, flame color, and the time required to heat water using used oil as fuel in a stove. The stove was tested under different air flow conditions, and flame temperature and color were observed in three stages. Additionally, the time taken to heat water to approximately 90 °C was recorded. At the lowest air flow rate of 15 m/s, the flame temperature reached 251.5 °C, and the water heating time was 187 seconds. At the highest air flow velocity of 29 m/s, the flame temperature increased to 273.7 °C. These results indicate that higher air flow velocity lead to increased flame temperatures and improved heating efficiency, suggesting that optimizing air flow in used oil stoves can enhance their performance while supporting more sustainable fuel practices.
