ANALISIS KARAKTERISTIK NYALA API CAMPURAN BAHAN BAKAR PERTALITE DAN BIOETANOL BERAS KETAN PUTIH (ORYZA SATIVA GLUTINOSA)

Abstract

The fuel needs is a crucial issue that must be a concern to all sides, because of the availability is running low, especially that came from non-renewable resources. Therefore, an alternative source of energy such as bioethanol is required, which can be used as a fuel mixture. The basic ingridients that used to make bioethanol is white sticky rice. The white sticky rice bioethanol has an ethanol rate of 99,86%. The aim of this research is to analize the flame characteristics (burning time, flame height, flame temperature, and flame color) of pertalite (E0), white sticky rice bioethanol (E100), and biopertalite (E10, E20, E30, E40,E50, E60). This research was carried out by using an experimental method in the form of difussion combustion. During the data collection, each type of fuel was tested 3 times, with a volume of 2ml for each test. The instrument in this research are stopwatch, camera, LCD Digital Temperature, and ruler. a stainless steel plate was used as a fuel burning stove, with a size of 2.5 cm, a thickness of 0.2 mm, and has a concave shape. The research data were analyzed using quantitative descriptive methods. The research result that obtained are: The highest flame height was produced by pertalite E0, with an average height of 26.7 cm, and the lowest was bioethanol E100, with an average height of 8.8 cm. The longest combustion duration was produced by bioethanol E100, with an average time of 249 seconds, and the fastest duration was produced by pertalite E0, with an average time of 218 seconds. The highest flame temperature was produced by bioethanol E100, with an average temperature of 978.2 °C, and the lowest temperature was pertalite E0, with an average temperature of 796.°C. The dominant color produced by bioethanol E100 is blue.
