Abstract

Year by year, fossil fuels start to run out due to the increasing marketing of fuel due to the increasing number of vehicles in Indonesia. It is proven by the increase in fuel prices in Indonesia, which means that the available oil is running low. To overcome the excessive use of fossil waste, researchers use alternative materials which are recycled from waste or commonly called bioethanol. The purpose of making a fuel mixture is that in addition to materials that are easily available, bioethanol does not damage the surrounding environment because it uses materials that do not contain harmful substances, which can be recycled such as fruit peels or plant waste. The study method used is experimental, using a Yamaha Force 115cc motorcycle. Data is obtained directly by observing the analysis of experimental results and then concluding in the form of graphs and tables. This test uses a dynamometer to determine the power and torque produced, while for testing the rate of fuel consumption using a measuring burette, then the calculation of fuel consumption is carried out. The results showed that there were differences in power, torque, Bmep and fuel consumption produced by variations in fuel. For maximum power produced on E15 fuel of 6.47 hp and a maximum torque of 5.16 Nm. For the lowest power produced on E20 fuel of 5.67 hp and the lowest torque of 4.39 Nm. The lowest fuel consumption was found in the use of E10 fuel of 0.000338 kg/hP while the highest fuel consumption was produced by E20 fuel of 0.0000406 kg/hP. For the highest Bmep on E15 fuel of 11.91 Psi and the lowest on E20 fuel of 11.39 Psi.

Abstract

Along with technological developments, the system in vehicle engines is also experiencing developments, with the technology embedded in vehicle engines it is hoped that vehicles can become more efficient, powerful, produce low emissions, even vibration and sound produced is very small. This also needs to be supported by using the right fuel. Bioethanol is an alternative fuel made from vegetable and can produce complete combustion. The data collection method is by recording the proportion of the bioethanol mixture with 92 octane fuel and changes in engine speed, when vibrations occur, the LCD vibration meter will display the vibration value. Engine speed starts from 1500 to 8500rpm with a change of 1000rpm each rotation. From the tests carried out, at engine speed of 1500 to 2500 rpm the 5% mixture is a good mixture because the vibration value is lower than before mixing. Then for engine speed of 3500 to 8500 rpm a 10% mixture is a good mixture because the vibration value is lower than before mixing and lower than other mixtures.

Abstract

Naphthalene is a chemical hydrocarbon compound with the chemical formula C10H16O. Napthalene is a simple polycyclic aromatic hydrocarbon compound, in the form of a white crystalline solid with a characteristic odor and detectable by the sense of smell at concentrations as low as 0.08 ppm. As an aromatic compound, napthalene's structure consists of a pair of linked arene groups or benzene rings. Objective: To determine the ratio of the power produced by a gasoline engine using a mixture of naphthalene with 90 fuel compared to the use of pure fuel in the engine. Knowing the effect of exhaust emissions produced by gasoline engines using 90 octane fuel, with a mixture of naphthalene and without a mixture of naphthalene. The method used in this study was experimental, tested only with pertalite fuel, Pertamax and added camphor (Napthalene) consisting of 5gr, 10gr, 15gr with 2lt volume of 90 octane fuel fuel. The conclusion is expected that the addition of napthalene has an effect on power and exhaust emissions.

Abstract

This research focuses on the use of bioethanol mixed with 92-octane gasoline as an alternative fuel to improve engine performance and reduce emissions. The main problem addressed is the lack of optimization in the bioethanol and gasoline mixture ratio, which affects combustion efficiency and engine performance. The results show that mixing bioethanol with gasoline improves the brake mean effective pressure (BMEP) and decreases specific fuel consumption (SFC) at certain engine speeds, indicating enhanced combustion efficiency. However, the mixture ratio beyond a certain percentage (30% ethanol) leads to decreased performance, showing the limits of bioethanol use in fuel blends. The distinctive feature of this study is the comprehensive evaluation of different bioethanol proportions (13%, 15%, and 17%) and their effect on engine performance, providing more specific insights into the optimal fuel mixture for various engine conditions. The results are particularly useful for the automotive industry and policymakers looking to implement bioethanol as a sustainable alternative fuel

Abstract

High concentrations of pollutants from incomplete combustion of motor vehicles have an impact on the surrounding environment and the health of living things. Incomplete combustion as a result of the design of the combustion chamber and the type of fuel used that does not correspond to its compression ratio. To improve the octane value of the fuel can be mixed bioethanol, because this alternative fuel is environmentally friendly. The purpose of knowing how much the change in the emission values of CO, HC, O2 and CO2 when using 92 octane fuel, and 95. additionally determines the change when using 92 octane fuel mixed with bioethanol 5, 15, 25%.

Abstract

In this modern era, technological developments are growing so fast, from information technology, communication technology, transportation, medical to industrial technology. One of the advances in the rapidly developing industrial world is the technique of coating metal or material surfaces. There are many methods of material surface coating techniques such as Physical Vapor Deposition (PVD), implantation, radio frequency (RF) sputtering, chemical vapor deposition, polymer supported electrodes (PSE), and electrochemical deposition. The Electrochemical Deposition method is a simple method with cost advantages, but this method requires processing of liquid waste which has recently become a public concern regarding environmental pollution. The APD (Arc Plasma Deposition) method has a higher level of satisfaction in fulfilling the requirements for deposition of a material, namely it is easy to control the size of the particles to be deposited and is faster in the deposition process and also has a very small impact on environmental pollution. This method requires quite large assets for its application so not many people know the stages of layer deposition. Therefore, the preparation of a prototype of a laboratory scale thin film growth machine was carried out and can carry out the deposition of a material onto a material. To optimize the layer growth results, adjustments are required in the machine parameter settings and the pure gas rate used
