Aplikasi Penggunaan Serah Wangi Sebagai Bioaditif Alami untuk Karakterasi Unjuk Kerja dari Mesin Diesel

Abstract

The consumption of diesel fuel in Indonesia is increasing every year, one way to overcome this problem is to use natural bioaditive in the form of essential oils found in Indonesia. Essential oils used in this study are fragrant lemongrass because fragrant lemongrass contains carboxylic compounds (-COOH) [1,2,3]. With the aim of improving engine performance and reducing fuel consumption. This research was conducted by mixing fragrant citronella oil with diesel oil with a percentage of 1%, 0.5% and 0.1% of the total volume. Diesel engines are operated with variations in loading 200, and 2000 W at a constant engine speed of 1500 rpm. The variables measured and calculated in this experiment are power, torque, Break Mean Effective Pressure (BMEP), Specific Fuel Consumption (SFC). The results showed that adding citronella oil to diesel fuel with a percentage of 1%, 0.5% and 0.1% significantly reduced fuel consumption by 15.5%, 3.6% and 2.6% respectively. The maximum reduction in fuel consumption reaches 0.055 liters / hour at 200W loading with a bioaditive level of 0.1%. The next study planned is to mix clove oil and citronella oil as bioaditive so that it is expected to reduce fuel consumption and engine corrosion.Abstrak: Konsumsi bahan bakar diesel di indonesia meningkat pada setiap tahunnya, salah satu cara untuk menangulangi Gambar 1.

“…Transesterification is the process of converting triglycerides (vegetable oils) into alkyl esters and glycerol by reacting them with an alcohol. The trans esterification reaction is shown in Equation (2) [28].…”

“…FTIR is an analytical method that can be used to determine the functional groups of a compound by recording the residue spectrum with energy absorption by organic molecules in the infrared [26,27]. Biodiesel B100 which has been transesterified was analyzed using the FTIR instrument to prove that a methyl ester functional group will be formed [28].…”
