Abstract

Quality of product in various industries, especially in metal industry is the most attention so the product can compete and attract consumers. Surface roughness is one of the demand that must be fulfilled because it can be the initiation of cracks, especially when material receives recurring and fluctuating loading. Therefore, low surface roughness can produce a product with longer lifespan material. The goal of this study is to determine the most optimal combination of electroplating process with factors variety of voltage (volts), temperature (℃), and time of immersion (minutes) to produce a low values of surface roughness. This study uses an experimental design with Taguchi method. Contribution factors of control that produce the surface roughness values ​​were influenced significantly by control factor voltage (volts) amounted to 77.31% with an average roughness value of 1.29 μm. This is due to the increase in voltage which causes the deposition of electrolyte ions which is faster in the deposition structure of the specimen. Where as other control factors were not effected significantly on the temperature control factor amounted to 4.85% with an average roughness value of 1,32 μm. These results are possible because the temperature variations used (40℃ to 50℃) are still within the optimum operating temperature. And the other control factors is immersion time amounted to 10.13% with an average roughness value of 1,32. The result ware obtained because the length of coating time affected the quantity of deposition of nickel ions on the surface of the specimen. The result of optimal condition is the voltage level 2 (6 volts), the temperature at level 2 (45℃), and the immersion time at level 3 (25 minutes).

Abstract

To reduce dependence on oil usage that increasing every day, many countries have adopted a substitution of petroleum fuels with renewable fuels such as ethanol is used as a blend in gasoline. Because ethanol can be produced from agricultural products such as corn, sugarcane, rice, etc., then the ethanol is one of the best alternative fuel in motor gasoline. Blending gasoline with ethanol would not fully produce a homogeneous mixture, need for additional treatment to obtain a more homogeneous results, one way is to heat the fuel. If the fuel is heated, there will be expansion or changes in fuel volume, in addition to the viscosity of the fuel will be decreased. It’s can be explained by the theory of thermodynamics, which states that the higher the temperature of a fluid, the fluid molecules will move quickly so at fixed volume will increase the pressure. Fuel with low viscosity will be atomized better, resulting smaller granules. With these conditions the process of mixing fuel with air will be more homogeneous so that the fuel burn more. The results obtained from testing the performance of the engine is the highest maximum torque obtained when using T40˚C fuel, with 6.37 Nm at 3400 rpm, increased 22.5%. The highest maximum power obtained when using T40˚C fuel with 3.450 HP at 5600 rpm, increased 5.11%. lowest Fuel Consumption average obtained at T40˚C fuel with 4.46% more efficient. Keywords: gasoline, ethanol

Abstract

The air pollution rate caused by the vehicles in big cities is now reach the critical limit. It affects the environmental health as well as the financial factors. To reduce the pollutant gas from the vehicle engines emission, a technology is needed. One of the technology is the application of catalytic converter  inside the exhaust emission. A research has been done on 125 cc motorcycle engine to modify its exhaust emission. The catalysts used in this research was made of copper and designed using the honeycomb system with various diameters ( 4, 6, 8, 10, 12 mm). The observation variables are catalyst temperature, CO and HC emission rate. The emission of CO and HC from the sample engine was then compared with the standard emission rates. Result showed that increase of the copper catalyst temperature resulted in decrease of  CO and HC emission rates. The decrease started to occur for all the catalysts at 225 oC. Optimum convertion efficiency is up to 47,93 % (CO) and 50,36 % (HC). Both optimum efficiency reached at the temperature of 325 oC using 8 mm diametered catalysts. Keywords : air pollutions, honeycomb system catalytic converter, temperature and copper

Abstract

Al-SiC is a composite composed of AA6061 as a matrix and SiC as a reinforcement particle. The variation of mass added will affect the mechanical properties of the composite because Al-SiC is hardenable, which means that its mechanical properties can be improved by adding the reinforcement component. However, an excessive portion of SiC leads to a decrease in mechanical properties. The purpose of this study was to find the optimal composition of the addition of SiC into the aluminium matrix to gain maximum tensile strength and hardness. The mass fraction variation that would be used in this composite was the addition of 6%, 8%, and 10% SiC with the addition of 1% Mg as a wetting agent. The mixing process used the stir casting method. The process of adding SiC and Mg was carried out by melting the aluminium while stirring it for a certain time before it went to the furnace. The ASTM E8/E8M standard was used for observing the tensile strength of the specimens. Machining was carried out before testing. The specimens were also tested for hardness using the Rockwell hardness method. The result shows that the addition of SiC at the amount of 6%, 8%, and 10% SiC increased the ultimate tensile strength by154.10 MPa, 175.01 MPa, and 198.14 MPa, respectively. Similarly, the hardness also increased up to 30.1 HRF, 48.1 HRF, and 66 HRF, respectively. Microstructure observation also confirmed that a 10% SiC fraction results in less defect and good wettability. The addition of 10% SiC and 1% Mg resulted in maximum tensile strength and hardness and the best microstructure.

Abstract

Research on emission spectra of metal combustion at temperatures above the boiling point of Al has been successfully carried out. This method can be used as a qualitative characterization of the presence of elements or compounds involved in the combustion process. Recording of emission spectra data was carried out during the process of burning Al powder with oxygen O in an air plasma flame at atmospheric pressure. The burning characteristic of Al was detected at the peak intensity of the wavelength λAl = 396 nm, and the reaction products of AlO with the peak intensity of the wavelength λ­AlO were 471, 489 and 512 nm, respectively. The absolute temperature of the plasma flame black body was 5660 K based on the highest peak intensity λAlO = 512 nm. The increase in emission intensity was quite significant when Al was started to be injected at 1.25 seconds, followed by an unstable plasma form. The steady state of the plasma flame indicates a full reaction in the vapor phase of AlO(g) in the form of Al sub-oxide and alumina before condensing on the outer surface area of ​​the plasma. High temperature thermal plasma-air can increase the homogeneity of the atomization process of particles into gaseous vapor which is an important initiation where nanoscale AlO particles begin to form.

The number of energy demand these days is very high. This shows the need for new inonovation to solve the problem of energy needs, one of which is the use of Phase Change Material (PCM) as a heat exchanger material. The purpose of this research is to know the characteristics of PCM with addition cooking oil and paraffin. The percentage of cooking oil and paraffin are 30%, 40%, and 50% of total volume. The research was start with heating process during 1 hours with temperature ± 25oC. Result of this research shows PCM paraffin - cooking oil with 50% mixture is the best cooling speed PCM, next is PCM paraffin - cooking oil 40% mixture, and the last is PCM paraffin - cooking oil with 30% mixture. On the cooling process, the 30% cooking oil mixture can hold the temperature longers than the other, while the 40% cooking oil mixture has second position, and the last is 50% cooking oil mixture. The conclusion is the addition of cooking oil can improve thermal conductivity of PCM.
