ANALISA PENGARUH VARIASI CAMPURAN BIOETANOL DARI BIJI BUAH PALEM (Adonidia Merrillii) DAN BBM TERHADAP KADAR EMISI GAS BUANG PADA MOTOR 4 LANGKAH INJEKSI

Abstract

This research aims to analyze the effect of varying bioethanol mixtures from palm seeds (Adonidia Merrillii) and fuel oil (BBM) on exhaust gas emission levels in 4 stroke injection motorbikes. The background to this research is based on the increasing need for energy and the negative impact of the use of fossil fuels which contribute to air pollution and climate change. The method used in this research was an experiment with various fuel mixture treatments, namely E0 (pure pertalite), E10 (10% bioethanol), E20 (20% bioethanol), and E30 (30% bioethanol). The test was carried out using a 2017 Yamaha Aerox motorbike engine, and exhaust emissions were measured using an Emission Gas Analyzer to determine CO, CO2, HC, O2 and Lambda emission levels.The research results show that the addition of bioethanol to the fuel mixture has a significant effect on reducing exhaust emissions. The higher the concentration of bioethanol, the lower the levels of harmful gas emissions produced. It is hoped that this research can contribute to the development of alternative fuels that are more environmentally friendly, as well as provide input for motorbike manufacturers and the government in efforts to maintain air quality and support environmental programs.
