Abstract

Research on the effect of the concentration of the inhibitor on the corrosion behavior of carbon-steel material has been done. The research was started by immersing the prepared carbon-steel plate in a 1 M HCl en-vironment. After that, corrosion inhibitor was added with several concentrations, which are 0, 100, 200, 300, and 400 ppm in to that environment, to be stirred using a magnetic stirrer at 300 rpm for 30 minutes under room temperatur condition. The effect of the added inhibitor was then analyzed using the Electrochemical Impedance Spectroscopies (EIS) method. The experiment results showed that the greater the concentration of the inhibitor, the greater the resistance, so that the metal is more pro-tected from corrosion attack. The calculation results showed that the inhibitor efficiency is directly proportional to the concentration of inhibitor that is achieved at a concentration of 400 ppm with an efficiency of 71.24%.

Abstract

Electric mobility mode could be a great opportunity to reduce emissions from the transportation sector. The future mobility calculator and electric car power demand, developed by Coalition for Urban Transitions and International Energy Agency, respectively, were used to analyze Indonesia’s shifting strategy toward electric mobility. It was shown that going to electric mobility will reduce 90% of Indonesia’s emissions from the transportation sector by the year 2050. Nevertheless, the charging infrastructure must be improved quickly to provide a proper ecosystem for electric mobility. Additionally, the electric vehicle waste management system is urgently needed soon. The success of shifting toward electric mobility not only benefits Indonesia’s environment but also strengthens its international credibility for sustainable development.
