The method used is design thinking as a framework and kansei engineering to translate the emotions of application users, as well as using the system usability scale for usage testing. The results of this study based on partial component analysis obtained two user interface designs formed based on the design elements that have been made. The results of the design were tested on performance matrics and System Usability Scale (SUS). It was found that concept one was the best with an effective value of 100%, an efficient value of 34.8 seconds (scenario one) and 33.1 (scenario 2). eror value of one and with an SUS value of 90.]]>
