Abstract

Fuel needs are a big problem experienced by some countries in the world. Bioethanol is usually made from ingredients containing starch, sugar and cellulose that are widely contained in the musa paradisiaca stem bulbs. The purpose of this study was to determine the characteristics of the flames from bioethanol musa paradisiaca stem bulbs and pertalite. The research was conducted by the method of diffusion combustion using a wick lamp. Variations of the fuel mixture used are E0, E10, E20, E30, E40, E50 and E100. The fuel is burned as much as 1 ml with a burnt wick of 7,5 mm. The tools for research are wick lamp, wick, lighter, table, tripod, thermocouple, glass bottle, spuit and aquarium, while the research instruments are camera, stopwatch, ruler and LCD Digital Temperatur TM-902C. The research materials were bioethanol from musa paradisiaca stem bulbs and pertalite. The bioethanol musa paradisiaca stem bulbs used in this study had an ethanol of 99,66%, a heating value of 7280,5 kkal/l, a viscosity of 1,14 Cps, and a density of 828,6 kg/m3. The best results from characteristics of the flame were the highest flame at E0 which was 9,9 cm, the fastest combustion time at E0 was 179 seconds, the highest flame temperature at E100 was 915,2°C and the dominant flame was blue in the fule mixture E100. It is hoped that the results of this study can be used for further research, namely research for premix combustion to determine the performance and emissions of gasoline engines
