PENGARUH PEMAKAIAN HYDROCARBON CRACK SYSTEM (HCS) TERHADAP PERFORMA SEPEDA MOTOR  SUPRA X 125 TAHUN 2009

Kendaraan bermotor di Indonesia yang menjadi sumber emisi gas buang terbesar adalah sepeda motor. Ini merupakan kurangnya perhatian pengguna kendaraan bermotor dengan perbandingan kompresi mesin kendaraan yang tinggi cenderung memilih mengisi bahan bakar sepeda motornya dengan premium yang harganya lebih murah namun memiliki angka oktan yang rendah. Hal ini tentu akan menimbulkan masalah terhadap pembakaran yang tidak sempurna. Efek yang ditimbulkan adalah menyebabkan meningkatnya polutan pencemaran udara. Untuk mengatasi permasalahan diatas adalah dengan cara menggunakan Hydrocarbon Crack System (HCS), HCS bekerja untuk menyempurnakan proses pembakaran, sehingga dapat menurunkan kadar emisi gas buang kendaraan. Tujuan dari penelitian ini melihat pengaruh penggunaan Hydrocarbon Crack System (HCS) terhadap performa dan kandungan emisi gas buang yang dihasilkan. Berdasarkan hasil penelitian diperoleh bahwa penggunaan HCS pada sepeda motor Honda Supra X 125 dapat menurunkan emisi gas CO sebesar 40 %. Untuk emisi gas HC penggunaan HCS dapat menurunkan emisi gas HC sebesar 37%,sedangkan untuk emisi gas buang CO2 penggunaan HCS dapat meningkatkan emisi gas CO2 sebesar 12.98%. Motor vehicles in Indonesia which are the largest source of exhaust emissions are motorbikes. This is the lack of attention of motorized vehicle users with high engine compression ratios, which tend to choose to refuel their motorbikes with premium which is cheaper but has a low octane number. This of course will cause problems with incomplete combustion. The resulting effect is to increase air pollutants. To overcome the above problems is by using the Hydrocarbon Crack System (HCS), HCS works to improve the combustion process, so that it can reduce the levels of vehicle exhaust emissions. The purpose of this study is to see the effect of the use of the Hydrocarbon Crack System (HCS) on the performance and content of the resulting exhaust emissions. Based on the research results, it was found that the use of HCS on a Honda Supra X 125 motorcycle could reduce CO gas emissions by 40%. For HC gas emissions, the use of HCS can reduce HC gas emissions by 37%, while for CO2 exhaust emissions, the use of HCS can increase CO2 emissions by 12.98%.

The technological development of the automotive sector is increasing, every year there is an increase in the production of motor vehicles in Indonesia. The increase in motorized vehicles will certainly have an impact on the use of fuel oil which is also increasing. Though fuel oil is a non-renewable fossil fuel, so that continuous use can lead to scarcity of fossil fuels someday. In addition to causing scarcity of fossil fuels, the increasing number of vehicles will also cause the surrounding environment to be increasingly polluted by the exhaust emissions from the combustion process of the motorized vehicles. Various alternatives are used as a mixture of fuels to reduce fuel consumption and vehicle exhaust emissions, such as ethanol, hydrogen, butanol, biodiesel, methanol etc. The purpose of this literacy study was to determine the effect of using ethanol on fuel consumption and its economic value. Based on the results of a study of literacy is known that the addition of ethanol does reduce the level of fuel consumption, However, if viewed from an economic perspective, the addition of ethanol has actually caused the purchase price of fuel to increase, this will certainly hinder the growth of the desire to use ethanol as an alternative source of fuel substitute by the people of Indonesia.

The high population in Indonesia has an impact on increasing the mobility of the population in work and activities, which is followed by the increased transportation facilities needed by the community. One of the negative effects of the increasing number of vehicles is the danger of exhaust emissions. One way to minimize the danger of exhaust gases is to regulate the mixture of air and fuel on the gasoline engine. In Yamaha injection motors there is a CO setting technology, this technology will have an impact on fuel use. The standard CO on a Yamaha motorbike is 0 and can be added or reduced (±) until it reaches 30. Increasing CO one strip will cause the fuel sprayed by the injector to be reduced by 0.05 cc. Examination of exhaust gas emissions is carried out using the Qrotect 401 Engine Gas Analyzer which is capable of measuring CO2, O2, CO, HC and Lamda. Based on the test results show that the lowest exhaust emissions are produced by the vehicle at 2500 rpm and in CO-30 mode settings, namely CO gas emissions of 0.49%. So we can conclude that the lowest exhaust gas emissions are produced by the vehicle at rpm 2500 with CO-30 settings. In addition to co mode settings, variations in engine rpm also affect exhaust emissions. In different modes but with different rpm the results will also be different. In the CO 10 mode setting with rpm 1400 CO gas emission is produced at 2.102 while at 2500 rpm is produced 0.821. So at rpm 2500 produced exhaust emissions lower than rpm 1400. There is a significant effect between CO mode settings and engine rpm on motorcycle exhaust emissions.

Sulfur dioxide is a major constituent of exhaust gas generated by diesel engines. The mainimpact of SOx (S02 and S03) contaminant is the generation of very sharp odor, the eventualoccurrence of corrosive acid rain, where as to humans such contaminants may cause irritation to eyes,skin and repiratory systems, and may prove to b~ fatal.The final produeNtf chemical reaction, H2S04 may cause corrosiveness, acid rain, and irritationto the eyes, skin, and respiratory tract, and may even be fatal, therefore it is deemed necessary toinitiate control of exhaust emissions from diesel engines. One of the many methods is the use of asaturated solution of lime water (CaOH2)as absorbent to reduce the said emissions.The purpose of this study was to determine the capacity of a saturated aqueous solution of limeor Ca (OH) 2 in lowering the levels of S02 in the flue gas emission from diesel engines (mobilesources).This is a pre-experimental study using One Group Pre-PostTest Design, this study was carriedout by conducting measurements on 6 samples of diesel engine exhaust emissions where 2 (two)measurements were done before and 4 (four) samples after passing through saturated lime waterabsorbent (CaOH2). Duration of sampling ranged between 20 -25 minutes.The results indicated the average levels of SOx before passing through saturated lime water(CaOH2) was 117,355 mg/m3 and the mean level of S02 after passing through a saturated lime waterwas 79,90 mg/m3. There was a decline in the average levels of S02 at a value of 37,455 mgr/m3 orby 31,90%This study concluded, that the lime water (CaOH2)solution was able to reduce the level of S02in exhaust emissions of a diesel engines by 37,455 mgr/m3 or 31,90%.It is suggested to owners of diesel engine motor vehicles to always perform proper maintenanceof their vehicles, and citizens (especially those living on the outskirt of a highway), in order to helppreserving the environment, are expected to plant trees and various other plants that can absorbcontaminants or can be used as indicators of pollution by motor vehicle exhaust emissions.

The development of transportation technology now has made distance become increasingly meaningless, but without realizing there has been a degradation of the environment as a direct impact of the development of transportation technology. Exhaust emissions produced by each vehicle have now become the main source of pollution, which is about 70% of all factors causing pollution. Unconsciously that so far the air quality that is inhaled by the community has slowly decreased so that it is not realized until an adverse impact appears, then the community then realizes that there has been a very complicated problem as a result of transportation that is less environmentally friendly. Most of the fuel for transportation comes from refined petroleum which is a non-renewable natural resource so that on the one hand it has caused air pollution which greatly affects health besides the amount of raw material for fuel production of these vehicles is also running low so prices are set for consumption society also becomes more expensive.The purpose of this research is to find out how much the level of air pollution in Bali Province at several sample points as a result of motor vehicles, to find out the type and amount of hazardous gas content produced by motor vehicles in Bali Province, to determine the impact caused by the exhaust gas of the vehicle on the health of the respiratory tract of residents of the Province of Bali, as well as ways that can be taken to reduce the negative impact resulting from pollution caused by vehicle exhaust emissions.
