ABSTRAK Penurunan kualitas udara pada bumi terus menurun. Ini disebabkan oleh polusi udara semakin lama semakin meningkat. Peningkatan jumlah kendaraan juga menjadi salah satu penyebab menurunnya kualitas udara. Penegakan aturan yang ketat dalam pengendalian pencemaran pada emisi gas buang semakin diperketat. Oleh itu diperlukan suatu bahan bakar kendaraan yang dapat mengurangkan emisi gas buang pada kendaraan. Pada saat sekarang ini pencarian bahan bakar ramah lingkungan difokuskan dengan menggunakan aditif berbahan dasar alami. Dengan demikian perlu diteliti penambahan aditif ditambahkan ke minyak solar, dengan tujuan untuk mengurangi emisi gas buang. Sebuah mesin diesel satu silinder telah digunakan yang digabungkan gas analyzer Bosc tipe BEA 150 / 250 / 350. Oksigenat berbahan dasar nabati digunakan sebagai aditif dalam bahan bakar diesel dengan campuran 1% - 5% volume. Tes emisi gas buang dilakukan pada kecepatan antara 900 - 1.700 rpm dan kondisi beban penuh. Percobaan dilakukan untuk mendapatkan parameter emisi gas buang. Hasil percobaan menunjukkan bahwa penambahan aditif oksigenat sebanyak 1 % bisa menurunkan jelaga 30%, meningkatkan CO2 sebanyak 5%, menurunkan CO 35% dan peningkatan NOx sebanyak 9% dibanding solar murni. Kata Kunci : Mesin diesel, Oksigenat, Emisi Gas Buang ABSTRACT Decline in air quality on earth continues to occur. One of its causes is air pollution which is the mistake of vehicle exhaust emissions. Strict enforcement of pollution control on exhaust emissions is one way to control exhaust emissions. It is therefore necessary to fuel a vehicle that can reduce exhaust emissions on vehicles. At the present time this environmentally friendly fuel search is focused using natural based additives. Thus it is necessary to examine the addition of additives added to the diesel oil, with the aim of reducing exhaust emissions. A single-cylinder diesel engine has been used which incorporates a BEA 150/250/350 Bosc gas analyzer. Vegetable oxygenates are used as additives in diesel fuel with a mixture of 1% - 5% by volume. The exhaust emission test is carried out at speeds between 900 - 1,700 rpm and full load conditions. The experiment was conducted to obtain the parameters of exhaust emissions. The experimental results show that the addition of 1% oxygenate additive can decrease carbon 30%, increase CO2 by 5%, decrease CO 35% and increase NOx by 9% compared to pure diesel. Keyword : Diesel Engine, Oxygenat, Emission Engine

Abstract: Motor Vehicle Pollution Doesn't Affect Against ISPA Disease. Air pollution is a problem that often occurs in the big cities, one of which is in the city of Bandung. Air pollution can cause various diseases from the most important ones namely respiratory, cardiovascular diseases, and to other diseases that attack certain organs. Based on the results of the study, air pollution from the transportation sector reached 60 percents, therefore this study will highlight the impact of motor vehicle air pollution on human’s health in Bandung, especially Acute Respiratory Infections (ARI), because the disease is the 2nd largest of the 20 biggest types of diseases in Community Health Centers / Puskesmas in Bandung. From several air pollutant parameters resulting from vehicle exhaust emissions, SO2 compounds were studied, because SO2 can cause irritation to the respiratory tract. This research using descriptive method, it can be concluded that air pollution caused by vehicle exhaust emission gas doesn’t directly affect the occurrence of Acute Respiratory Infections (ARI) in Bandung. The disease can occur due to other factors not examined in this paper, due to indoor air pollution, cigarette smoke pollution, industrial pollution or the continued use of synthetic chemicals.

High Level

The presence of one or more contaminants (harmful substances) in the atmosphere in a specific quantity, for such duration, which is injurious or tends to be injurious to human health, welfare, animal, or plant life is called air pollution. Air pollutants are of commonly two types, which are produced through natural pollutants; they include dust (crustal material), sea salts, biological material, pollen, spores or plant-animal debris, volcanic eruptions (which release a very large quantity of gases and particles into the atmosphere), periodic forest fires, thunderbolts, wind erosion, and low concentration ozone. Other types of pollutants are produced in human-made (technical) environments, like mobile sources (cars, trucks, airplanes, marine engines, etc.) or point sources (factories, electric power plants, etc.). The high level of air pollution is a big problem all over the world and also in Afghanistan, and all residents of this country are severely exposed to this ever-worsening situation. Air pollution and other extraordinary environmental problems are factors that threaten the livelihood of millions of Afghans, as a study report shows that 60% of Kabul’s residents are exposed to increased levels of harmful toxins, such as, nitrous oxides and sulfur dioxide. According to the State of Global Air report, more than 26,000 afghan deaths could be attributed to pollution in 2007, but United Nations Assistance Mission in Afghanistan (UNAMA) documented nearly 3,500 civilian casualties from the war for the same time period, so air pollution is killing more Afghans than war because they burn anything possible to get energy and heat they need. Result of air sampling in major urban centers of Afghanistan shows high amounts of particulate matters (PM), benzo-a-pyrene, and polycyclic aromatic hydrocarbons (PAHs) originating from vehicle exhaust emission. The highest concentrations were founded in Kabul and Mazar-e-Sharif (13.6 ng/m3 ). The absence of industrial parks, nonconformity of environmental protection rules, especially by industries, urbanization, degradation of fertile lands, deforestation, seasonal winds, drought, internal migration, and low knowledge about pesticides and herbicides use, are factors that boost the severity of air pollution in Afghanistan. In Afghanistan, women are more exposed to high levels of indoor air pollution because they spend more time at home due to their cultural rules; also, women have responsibility for household activities, working in the kitchen to prepare food, they are exposed to poor sanitation and contaminated water supplies, they clean and sweep rooms and yards with inadequate protection equipment, which are significant sources of dust, so they are often exposed to high levels of smoke and dust for long periods.

: This paper presents the production of biodiesel from three different non edible oils of Pongamia, Mahua and Jatropha as an alternative fuel for diesel engine. Biodiesel is produced by followed transesterification process, using catalyst sodium hydroxide (NaOH) and methyl alcohol (CH3OH). A single cylinder four stroke three-wheeler auto diesel engine is used to evaluate the exhaust emission characteristics at a constant speed of 1500rpm with varying loads. Diesel as a reference fuel and cent percent of Pongamia Methyl Ester (PME), Mahua Methyl Ester (MME) and Jatropha Methyl Ester (JME) are used as an alternative fuel. The physicochemical properties of biodiesels are within the limits of international standards (ASTM D6751) noticeably. The results of tested biodiesels offer low exhaust emissions compared to diesel fuel, owing to presence of molecular oxygen and high cetane number. At maximum load the NOx emission reduced by 18.41% for JME, 17.46% for MME and 7.61% for PME. Low levels of CO emissions are recorded for JME (66%) followed by MME (33%) and PME (22%). Unburnt hydrocarbon emissions were reduced by 85.75% for JME and MME, for PME 14.28% reduction is observed. Exhaust smoke emissions are also reduced for PME and MME by 18.84%, for JME 14.49%. As a conclusion, it is observed that all the methyl esters exhibit significant reduction in harmful exhaust emissions compared to diesel fuel and JME is noted as a better choice.

Improving fuel consumption with lower exhaust emissions give more focused to all car manufactures. A higher engine performance with lower exhaust emissions requires a complete mixing process resulted in ultra-lean high combustion efficiency. Air intake temperature is one of the alternative strategies to improve fuel consumption and reduced exhaust emissions. This is due to the cold air is denser and contain higher oxygen availability. Air intake temperature will affect to the oxygen concentration in the charged air that influence the combustion process through ignition delay and fuel burning rate. The objective of this experiment is to investigate the effects of air intake temperature to the fuel consumption and exhaust emission at variation of engine speeds and constant load by using 1.6L gasoline engine. Air intake temperature was changed from 20 °C to 30 °C. The DaTAQ Pro V2 software was used to measure the engine fuel consumption while gas analyzer (MRU Gas Analyzer) was used to measure the exhaust emission such as Unburned hydrocarbons (UHCs) and carbon monoxide (CO). The results showed that fuel consumption, UHCs and CO emissions increased with the increase of air intake temperature. The increase of air intake temperature resulted in advanced and shorter combustion duration. Higher oxygen concentration at lower air intake temperature leads to the complete mixing process and complete combustion.  Therefore, the experimental results can be concluded that the lower air intake temperature resulted in improved fuel consumption and reduced UHCs and CO emissions.
