Abstract

Various efforts continously to be made by humans to overcome the energy crisis. Utilization of coconut shell and rice husk charcoal as adsorbents for combustion air can improve the quality of the combustion process. Both of these charcoal have the ability to attract water vapor in the air, so that when combustion air is contacted to these two charcoal, it will produce combustion air containing rich oxygen concentration. This will result in a better combustion process that occurs. The physical activation by heating using oven to these two charcoal can increase the adsorption ability of water vapor, which means the better the combustion process that occurs. Before being used, these two charcoal are formed into pellets with a diameter of 10 mm and a thickness of 3 mm, then heated in the oven at 3 various temperatures, namely 175, 200, and 225 oC. After that it is inserted into the frame, then mounted on a motorcycle filter. Tests of fuel consumption are carried out under running conditions at an average speed of 50 kph as far as 5 km, and stationary conditions at 1500 and 3000 rpm. The test results showed that the adsorbent activated at 225 oC was able to save the highest fuel consumption in both test conditions, namely 10.32% using coconut shell charcoal and 10.08% using rice husk charcoal on the road test. In stationary tests, coconut shell charcoal is also able to save fuel consumption higher than rice husk charcoal, which is 31.71% and 10.17% at 1500 rpm testing, and at 43.90% and 23.73% at 3000 rpm.
