THE EXHAUST GAS EMISSION TEST ON HONDA BRIO SATYA WITH VARIATION OF FUEL AND ROTATION ENGINE

The purpose of this research are: 1) Knowing the exhaust gas emission test result from Honda Brio Satya with variation of fuel 2) Knowing the type of fuel that produces the lowest exhaust gas emission value. This research is using experimental method. This research was conducted in the automotive workshop of SMKN Udanawu Blitar Regency. Test media is a Honda Brio Satya type E 2017. The emission test used QROTEC QRO 402 gas analyzer. The results show that: 1) There is influence of fuel type to vehicle exhaust emissions, both at idle and intermediate rotation; 2) The average of CO gas emissions at idle rotation with fuel of each premium, pertalite and pertamax are 0.026%, 0.023% and 0.003%. The average of HC gas emission at idle rotation in each fuel type are 87 ppm, 86.3 ppm and 30 ppm. Thus, pertamax fuel produces the lowest level of exhaust emissions. The third fuel type still meets the threshold of motor vehicle emissions threshold in accordance with PERMEN LH No. 5 of 2010 so it is worthy to be used as an environmentally friendly learning media.


INTRODUCTION
The automotive industry continues to grow rapidly, not least in Indonesia.
Gaikindo (2017) reported that throughout 2016, the sum of vehicle production reached 1,177,797 units and sales during of it's year reached 1,062,729 units.Production and sales increased compared to 2015 with production of 1,098,780 units and sales reached 1,013,291 units.
The data is in line with the BPS data.BPS (2017) released from vehicle data in 1987-2013 where every year the number of vehicles ranging from passenger cars, buses, trucks, and motorcycles tends to increase.
For example, in 2013 there was an addition of 9.7 million units, in 2012 increased 8.7 million units and in 2011 increased 8.6 million units.
The development of automotive industry still leaves three major issues, and this issues are a global issues.Kumara (General Secretary of Gaikindo) in Kompas.com (2017)  respectively.The highest value of HC gas emissions (4020 ppm) is generated when using premium fuel, but with premium also CO emissions at the lowest level of 0.76%.
The three findings are also in line with the results of a study by Prawoto (2011) which states that in vehicles operating within the city, the exhaust emissions (CO and HC) using pertamax plus fuel are better than using Liquid Gas Vehicle (LGV) .
Conversely, for out-of-town conditions, fewer CO2 emissions are generated when using LGV fuel instead of using pertamax fuel.
The fuel factor is not one of the causes affecting the exhaust emission levels of a vehicle, because combustion involves not only fuel but also air and ignition factors.

THEORETICAL BASIS Gasoline Engine
Gasoline engine is a type of motor fuel by using gasoline as a fuel source.Daryanto (2013: 1) states that motor fuel is a prime mover that converts fuel chemistry into heat

RESEARCH METHOD
This research is a kind of quantitative research.According to Sugiyono (2013: 34), quantitative methods are used when we want to know the effect of certain treatment.For this purpose the correct method is the experimental method.

Start
Checking by hand and eye to make sure everything is in normal condition (electricity, exhaust pipe etc) Turn on the engine to normal temperature Step on the gas pedal and keep the RPM at 3000 round for 30 s   The result of emission test with premium fuel at idle cycle (750 rpm) showed that CO gas concentration in three (calor) power by combustion.The heat is then transformed into mechanical power.The combustion process occurs inside the combustion chamber so that this type of motor is also known as internal combustion engine or I.C Engine.The burning process occurs when a machine meets several criteria.Daryanto (2013: 66) states that combustion can occur when there is fuel, air and fire (heat).These three conditions do not guarantee the complete combustion so that it is necessary to set the ratio of the amount of fuel and air with a certain ratio and also other factors namely the maximum (heat) flame.Based on the cycle work, the motor is divided into 2 parts, there are motor 2 stroke and 4 stroke.Daryanto (2013: 12) states that the 2-stroke motor is a motor that requires 2 times the piston step (one rotation of the crankshaft) to produce one work, while the motor 4-stroke is a motor that requires 4 times the piston step (2 times the spin axis crank) to produce a onetime effort.The steps of the piston are known by the steps of intake, compression, combustion and exhaust.At the intake step, the introduction of new gas into the cylinder through the suction valve.In the compression step, the pressure and temperature of the gas is increased by the compression of the gas by reducing the space.Position of inlet and exhaust valve closes.At the step of the combustion, the combustion pressure pushes the piston down and the position of the valve closes.At the exhaust step there is expenditure of used gas from the cylinder, through the exhaust valve.(Daryanto, 2013: 20).

Figure 3. Technique of Exhaust Emission Testing Sources: Wraiter (2017) trials resulted in average 0.026%.NOx gas concentration average 0 ppm and HC gas average 87 ppm.Based on the data and PERMEN LH No. 5 of 2010, the Honda Brio Satya type E 2017 with premium fuel still meets the emission threshold category where for production vehicles above 2008 at the time of maximum idle rotation testing of CO 1.5% and HC 200 ppm.The following data of exhaust emissions of Honda Brio Satya Type E 2017 by using fuel pertalite in several engine revolutions.Vol.3, No.1, July 2018 ISSN 2528-2611, e-ISSN 2528-2700 pertamax at idle rotation (750 rpm) showed that CO gas concentration in three trials resulted in average 0.003%.NOx gas content average 0 ppm and 30 ppm of HC gas.Based on the data and PERMEN LH No. 5 of 2010, the Honda Brio Satya type E 2017 with premium fuel still meets the emission threshold category where for the production vehicle above 2007 at the time of maximum idle rotation testing of CO 1.5% and HC 200 ppm.The three types of fuel in the idle rotation test are still included in the threshold of exhaust emissions based on PERMEN LH No. 5 of 2010.The best value is obtained when the experiment uses Pertamax fuel with the average CO value of 0.003%, NOx of 0 ppm and HC level equal to
