Abstract:
The use of fossil fuels in transportation equipment,
especially motorized vehicles, will have an extraordinary effect on air pollution. Therefore, air pollution
becomes very important problem today. The amount of
percentage of air pollution from transportation sources
in Indonesia is 70.5 % CO, 18.34 % HC, 8.89 % NOx,
0.88 % SOx, and 1.33 % particulate matter. Given the
danger of exhaust emissions, especially carbon monoxide which can cause death for humans who inhale it,
therefore efforts are needed to control air pollution from
motorized vehicles. There are several methods that can
be used, one of which is to use adsorbents. Activated
carbon can be used as an adsorbent. One alternative
that can be applied as an adsorbent is peat soil-activated carbon which is abundant and easy to make as an
adsorbent. By utilizing the abundant peat-soil which is a
great potential area of Banjarmasin, South Kalimantan.
In this experimental study; model l has a diameter of
20 mm, model 2 has an outside diameter of 20 mm and an
inside diameter of 10 mm, and model 3 is without adsorbent. The length of this model is the same. Testing with
a 2005 Honda Kharisma motor vehicle with an engine
speed of 1000, 2000, and 3000 rpm. CO and HC emission
tests using a gas analyzer were carried out. Testing was
also carried out using a dyno test to determine the engine
performance of a motorcycle that was installed with an
adsorbent on the exhaust gas. The results showed that
peat soil adsorbents with perforated circle designs can
reduce CO gas emissions by 55 % compared to the others. Besides that, the use of peat soil adsorbents with
hollow circle designs can also reduce HC gas emissions
by 3.51 %. The results of the engine performance test
showed that there was no significant effect of using this
adsorbent on torque and power.
In conclusion, peat soil adsorbents used to reduce
exhaust emissions in motorized vehicles can be applied.
