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.","PeriodicalId":233393,"journal":{"name":"NOZEL Jurnal Pendidikan Teknik Mesin","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122407904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RDF is a waste treatment that is used as an alternative energy material. The materials used to make RDF in this study were coffee grounds and bagasse. To make it, coffee grounds and bagasse are mixed and an adhesive is added. The mixture ratio is 100:0, 30:70,50:50,70:30, and 0:100 for the adhesive concentration using 10%, 20%, and 30%. The finished RDF-5 was tested by testing the burn time. The test was carried out at the Mechanical Engineering Education Laboratory, FKIP UNS. The method used is the experimental method. The variables studied in this study were the independent variable, the dependent variable, and the control variable. The independent variation consisted of composition variations between coffee grounds and bagasse with the following ratios 100:0, 70:30, 50:50, 30:70, and 0:100 and variations in adhesive concentrations of 10%, 20%, and 30%.
