Pengaruh Penambahan Gelling Agent Carbopol Dan Asam Stearat terhadap Nilai Kalor Etanol Gel

Ethanol gel is a semisolid fuel made from ethanol by mixing the gelling agent. Ethanol gel has the advantage of facilitating packaging, distribution and storage because it does not spill and flow easily. Another advantage of ethanol gel is that it does not smoke during the combustion process, does not cause soot and does not produce harmful gases. This research aims to compare the 2 best gelling agents and study the effect of adding the gelling agent to the calorific value. The process of making ethanol gel begins by inserting a gelling agent of 4-12% w into a beaker glass. Then add 20 ml of distilled water while stirring until the solution thickens. After that, slowly put 75 grams of 95% ethanol into the beaker which already contains the gelling agent solution. For the manufacture of ethanol gel with a stearic acid gelling agent, heating is done first in making the solution and left for 3 hours after mixing with ethanol. Based on the analysis, it was found that the highest calorific value was 12052.7 cal / g with stearic acid gelling agent in the addition of 12% (% w).
