Petroleum reserves will increasingly be depleted if alternative energy is not found. Therefore, various breakthroughs are needed to prevent an energy crisis from occurring. Simultaneously the researchers are also trying to find equipment that can save fuel consumption. To get a more effective and efficient flame, you can apply a magnetic field effect to the burning fire, especially in terms of the rate of burning of the fire. Fuel oil under normal conditions tends to be irregular and grouped together. By providing a magnetic field to induce the fuel oil, the hydrocarbon bonds will break and will make the chemical composition more homogeneous. The experimental research method is to heat ethanol until it is in the form of steam, then flow it to the burner which will then be given air which is controlled by the mass flow. The research began with the manufacture of magnetic induction from carbon steel wrapped in copper wire. Then testing the fuel by providing a magnetic field before the ethanol fuel enters the burner tip. The magnetic field helps the fuel ionization process, this ionization is needed so that the fuel can easily bind oxygen during the combustion process. If the ionization process goes well then the combustion process becomes more complete. In this ionization process, it will result in the formation of positively charged fuel molecules so that during combustion the combustion process will occur more quickly. The magnetic field will generate Far Infrared waves, which will strengthen the positively charged bonds in the fuel structure due to the ionization process and position these bonds in an orderly manner. This makes it easy for oxygen to react with fuel in the combustion process. With the electric motion force will increase the combustion temperature. The increase in temperature is caused by the process of ionization of the fuel due to the magnetic field generated by the electromotive force. The dynamic electromotive force causes the flame to increase when the current is flowing and decrease when the electric current is cut off. The resulting fire is more transparent, clearer and more visible. The direction of the N-S magnetic field causes the temperature to be higher than the direction of the N-N magnetic field. The magnetic field can affect the burning speed of the ethanol flame. In a poor mixture (ϕ <1) in the presence of magnetic influence, the rate of fire is lower without the influence of a magnetic field, but in a rich mixture (ϕ > 1) in the presence of a magnetic influence, the rate of fire is higher than without the influence of a magnetic field. Key words : Burning speed, premixed, Ethanol, Electromotive Force, Effect of Magnetic Field. 1. INTRODUCTION Ethanol is an environmentally friendly alternative (renewable) fuel that produces low carbon emissions compared to gasoline or the like (up to 85% lower). Basically, ethanol is made from sweet potatoes, corn or other plantation products and until now there has been no vehicle specifically designed to use 100% ethanol. The use of ethanol in vehicles usually uses 2 types of ethanol, namely ethanol 10 (E-10) which is a mixture of 10% ethanol and 90% gasoline and can be used in all the latest vehicles [1]. In general, the hydrocarbon molecules in fuel compounds will carry out vibrational activity towards the core. In addition, hydrocarbon compounds will tend to attract and attract intermolecular molecules so as to form clustered molecules (clustering). Clustering in this fuel causes the hydrocarbon molecules not to separate from each other when they react with oxygen. There is a rapid chemical reaction between the hydrogen and carbon in the fuel with the oxygen contained in the air. As a result of the clustering effect there is still fuel that has not been burned and turned into UHC (Unburned Hydrocarbon) and carbon monoxide. So to reduce emission levels and increase combustion efficiency, it is necessary to improve the atomization process. One way to improve the fuel atomization process is to apply a magnetic field to the fuel flow [2]. In everyday life, the emergence of an electric field is always accompanied by the emergence of a magnetic field. The use of a magnetic field in the fuel flow is as follows: 1. The magnetic field helps the ionization process in the fuel, this ionization is needed so that the fuel can easily bind oxygen during the combustion process. If the ionization process goes well, fuel consumption will be reduced because the combustion process is more complete.
