Penentuan Kinerja Kompor Bertungku Dengan Bahan Bakar Dari Campuran Minyak Jelantah Dan Pertalite
ABSTRACT
Kerosene is the fuel used in stoves, but the price of kerosene is very expensive. Based on the above, a mixture of used cooking oil with pertalite can be used as an alternative to kerosene fuel. This study aims to determine the effect of variations in the mixture between used cooking oil and pertalite (9:1, 8:2 and 5:5) on the color of the flame and the time needed to boil 1 liter of water, as well as the time test of 1 liter of mixed fuel being burned. on the resulting stove fuel, determine the characteristics of the resulting fuel and determine the best ratio of used cooking oil – pertalite mixture as an alternative to kerosene. Before use, 15 grams of detergent adsorbent was added to the used cooking oil, then a separation was carried out between the detergent adsorbent and the used cooking oil by filtering using gauze, then mixing 2 liters of used cooking oil with pertalite. The fuel mixture is analyzed before and after it is used on the stove. Stove performance is determined by the color of the flame, the time it takes to boil 1 liter of water and the time it takes 1 liter of fuel to burn out. The results showed that the best fuel performance was having a blue-red flame, the time to boil 1 liter of water for 22 minutes 49 seconds and the time needed for 1 liter of fuel to burn out was 1 hour 4 minutes 10 seconds. This fuel is a mixture of used cooking oil and pertalite in a ratio of 9: 1. The characteristics of this fuel include a density of 0.877 gr/cm3, a viscosity of 54.228 mm2/s, a heating value of 43.527 J/kg and a flash point of 39oC.
Keywords: detergent, stove, used cooking oil, pertalite.
