Abstract

This study aims to determine the effect of cooling media on microstructure and hardness values on alloy steel S45C using the welding method of Gas metal arc welding (GMAW). This research is using an experimental method. The data analysis technique used is descriptive comparative. The tool used for microstructure testing is Olympus Metallurgical Microscope and hardness test using the Vickers Hardness Tester. Based on the results of the study, it can be concluded that the results of the microstructure show an increase in the structure of pearlite after welding. In raw material, ferrite structures are seen evenly but in the welding results, GMAW which has cooled by using water, air, and oil cooling media show that ferrite is reduced in each specimen, so the pearlite structure dominates. The values of hardness and microstructure in the welding results using water, oil and aircooling media show differences in the level of hardness and microstructure. Specimens with water cooling media at the Heat Affected Zone (HAZ) test point have a higher hardness level of 315.4 VHN when compared to specimens using an oil cooling medium of 268.7 VHN and air conditioning media of 177.4 VHN. Specimens with water cooling media the microstructure in the Heat Affected Zone (HAZ) section showed more pearlite which was evenly distributed compared to specimens using other cooling media, or it could be concluded that the further away from the Las area and HAZ the smaller the pearlite content. This study shows that welding using variations in cooling media changes the microstructure and influences the hardness value of the S45C steel alloy

Abstract

Vehicle technology is still not effective in saving fuel consumption. Various attempts have been made to reduce fuel consumption in motorized vehicles. This is done to prevent the depletion of the availability of fossil energy, especially petroleum. One of the emerging technological innovations is the Magic ring. Magic ring is a technology to reduce fuel consumption by reducing the diameter of the exhaust manifold channel with a special design. This study aims to determine the effect of the use of the Magic ring on the fuel consumption of motorized vehicles (gasoline engines). This study used an experimental method on a single cylinder 110cc four-stroke gasoline motorcycle engine. This study uses three types of fuel, RON 90, RON 92, and RON 98 for fuel consumption in ml / minute, and data analysis using quantitative descriptive. The results of this study are looking for the most efficient fuel consumption in each type of fuel at 1500 rpm. The results show that there is an effect of installing a Magic ring in saving fuel consumption. Evidence of this is the increase in the value of fuel consumption savings with a percentage of 23.3% at RON 90, 21.5% at RON 92, 19.4% at RON 98. The test results show that the installation of Magic rings is effective in reducing fuel consumption and can used in the future to save fuel.

Abstract

The purpose of the study are analyzed the potential energy of durian peels as an ingredient of solid fuel use the conversion of biomass hydrothermal technology. This study used an experimental method with hydrothermal treatment. Variations used in this method are temperature variations of 180°C, 200°C, and 220°C with variations in holding times of 30 minutes and 60 minutes. To determine the fuel content of durian peels, heating values and proximate analysis were carried out to determine water content, ash content, volatile content, and carbon content. The test result showed that durian peels waste is suitable to be used as an alternative fuel that is suitable for lignite coal fuel. In testing, the highest calorific value is 4515.52 kal / gram which was equivalent to the calorific value of lignite coal (3500 - 4611 cal / gram) according to the American Standard Testing and Mineral (ASTM).

Abstract

This research has an objective to describe : (1) the effect of silicon addition to tin bronze alloy at an elastic properties; (2) the effect of silicon addition to tin bronze alloy at an impact power; (3) the effect of silicon addition to tin bronze alloy at a micro structure level. The research uses an experimental method with descriptive data analysis. The research sample is the result of tin bronze alloy plus silicon. The independent variables of this research are variations in the addition of silicon 1.5%, 3%, and 4.5%. The dependent variable of this research is tin bronze alloy. The results of this research indicate that the increased elastic properties are influenced by the addition of silicon which is known from the calculation of elastic modulus that the highest is 4.5% silicon variation has increased by 21.218% from tin bronze alloy. Broken toughness through the biggest impact test on the addition of 4.5% silicon has an impact value increase of 53.793%. The addition of silicon has an effect on the mechanical properties of the alloy where the elastic properties and impact strength have increased. The resulting microstructure explains that variations in the addition of silicon have an effect on the phase formed on the mechanical properties of the alloy. With the addition of silicon to tin bronze alloy can be recommended as a substitute for gamelan musical instruments.

Abstract

Solar and wind are sources of potential energy that are not widely used. The kinetic energy of wind and thermal energy of solar can be converted into electrical energy source. Both of these energy sources in addition to not polluting are also available in unlimited quantities.This experimental research studying the effect of the slope angle of solar panel to determine the most optimal angle and the feasibility between solar panels and wind turbines in the area of Campus V UNS. Variations of the angle that is used in this research is the angle of 18o; 24o; 30o; and 36o. The measurement is done by measuring the electrical current and the voltage of the electricity produced in solar panels as well as to measure the wind speed as a comparison to find out the electrical power generated in wind turbines. This research was conducted in the area of campus V UNS Pabelan for 30 days.The results showed that the power generated influenced the angle of the slope in the solar panel. The Highest power produced is 41.1 Watt at the intensity of the sunlight 120000 lux on the slope angle of solar panel is 24o, while at the slope angel of solar panels an 18o, 30o, and 36o, in respectively is 37.4; 39.7; and 38.6 Watts. This research states that solar panels produce electrical power more effective and optimal than wind turbines. The highest average of electricity power for 30 days generated by solar panels is 40.19 Watt at 11:20 a.m. while wind turbines produce the highest average of electrical power is 7.88 Watt at 15:40 p.m.
