PENGARUH KADAR INHIBITOR EKSTRAK KULIT BUAH RAMBUTAN DAN KONSENTRASI LARUTAN HCL TERHADAP LAJU KOROSI BAJA ST 37
Get PDFIndustrial manufacture of steel with pickling process method uses HCl solution as a cleaner. Besides as a cleaner, HCl solution can also causes a corrosion on steel product from pickling process. That corrosion can be controlled by corrosion inhibitor from organic material. Organic material consist of tannin compound that can react by forming a complex compound on the steel surface and protect it from corrosion attack. Organic material in this research is rambutan peel extract used as inhibitor corrosion with the values of 0.5%, 1.0%, 1.5%, and 2.0% in HCl solution with the values of 0.1 N, 0.5 N, and 1.0 N. St 37 steel is used as test sample in this research. The aims of this research are to investigate the effect of amount of rambutan peel extract and concentration of HCl solution toward the corrosion rate of St 37 steel. Weight loss method is used to calculate the corrosion rate and Two Way Anova is used as data analysis technique. The result of this research shows that there is an effect of the amount of rambutan peel extract as an inhibitor and concentration of HCl solution toward the corrosion rate of St 37 steel. Corrosion rate has the lowest value in the variation of 2.0% inhibitor and 0.1 N HCl with the highest efficiency value as 63.13%

Get PDFThe availability of fossil fuels in Indonesia has recently been running low due to exaggerated use of the fuel. To fulfill the electrical energy needs of the community which more environmentally friendly used, wind turbines can be used. In this study, researchers use a micro-scale horizontal axis wind turbine from wood and composite materials on the blades, where it try to determine the effect of each performance. This study uses an experimental method which is carried out at the Wind Tunnel Laboratory of the Mechanical Engineering Education, Sebelas Maret University. The variables are blades with a variety of composite and wood material. Performance of electrical power is investigated in this research. Data shows that the wind speed 5m/s - 6m/s composite without load produces the highest rotate, which is 544.64 rpm. While, wood material take lower at 494.2 rpm. The wind turbine is driven at 5 m/s – 6 m/s by using 12V of load. It produces 367.68 rpm and 6.771 watts for composites, and 303.6 rpm and 5.047 watts for wood. So it can be concluded blade materials could effect to the turbine performance
