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

New and renewable energy (EBT) is a source of energy that can be created by humans by utilizing solid waste from industrial processing. One example of making renewable energy is RDF. Refuse Derived Fuel (RDF) is a form of solid waste utilization that is used from industries and households which have a high calorific value which can be used as a new alternative fuel. RDF is the treatment of waste which is used as an alternative energy material. The materials used to make RDF in this study are coffee grounds and bagasse. For the manufacture of coffee grounds and bagasse are mixed and adhesive is added. The mixture ratio is 100: 0, 30: 70,50: 50,70: 30, and 0: 100 for adhesive concentration using 10%, 20%, and 30%. The finished RDF-5 is tested by testing the burn time. Tests were carried out at the Laboratory of Mechanical Engineering Education, FKIP UNS. The method used an experimental method. The variables examined in this study are the independent variables, the dependent variable and the control variable. The free variation consists of variations between the composition of coffee grounds and bagasse with the following ratios 100: 0, 70:30, 50:50, 30:70, and 0: 100 as well as variations in adhesive concentrations of 10%, 20%, and 30%. The dependent variable consists of burn time. The control variables consist of the RDF-5 printer with a pressure of 6 kg / cm2 and a filter used with a size of 10 mesh. The best test results for burning time are 30 bagasse + 70 coffee grounds mixed with 30% adhesive concentration with a result of 1370 seconds.

The data analysis technique descriptive analysis. The research was conducted at the Laboratory of the Surakarta City Transportation Office located at Jl. Menteri Supeno No.7, Manahan, Banjarsari, Surakarta. The tool for measuring CO and HC exhaust gases is the KOREA IYASAKA brand gas analyzer (TYPE AET-4000Q). The subject in this research was the  Yamaha Soul GT 2012 motorcycle. From the results of the research, it can be concluded: (1) The use of Ferrite Bead can reduce levels of CO and HC exhaust gas emission on Yamaha Soul GT 2012 motorcycle. The test results without the use of Ferrite Bead produced CO emission levels of 0.61% and HC of 122.67 ppm. Whereas in testing the use of Ferrite Bead near spark plugs obtained CO emission levels of 0.53% and HC of 101 ppm, and on testing the use of Ferrite Bead near the coil obtained CO emission levels of 0.60% and HC of 122.67 ppm; (2) The use of variations of the spark plugs type can reduce levels of CO and HC exhaust gas emission on Yamaha Soul GT 2012 motorcycle. The results of testing using Standard spark plugs (C7HSA) produce CO emission levels of 0.61% and HC of 122.67 ppm. While testing using Platinum spark plugs (CR7HGP) obtained CO emission levels of 0.59% and HC of 131.33 ppm, and testing using Iridium spark plugs (NGK CR6HIX) obtained CO emission levels of 0.60% and HC of 93.67 ppm; (3) Interaction of the use of Ferrite Bead and variations of the spark plugs type can reduce levels of CO and HC exhaust gas emission on Yamaha Soul GT 2012 motorcycle. Test results show the lowest levels of CO and HC exhaust gas emission, namely the use of Ferrite Bead near the spark plug and the use of Iridium spark plugs ( NGK CR6HIX) with the lowest exhaust gas emission results, namely 0.45% for CO and 80 ppm for HC.
