Evaluasi dan Rekomendasi Perbaikan Desain Antarmuka Pengguna Menggunakan Pendekatan User-Centered Design Pada Aplikasi PeduliLindungi

PeduliLindungi is an application that was developed to assist relevant government agencies in tracking to stop the spread Coronavirus Disease (Covid-19). This application relies on community participation to share location data with each other when traveling so that contact history tracing with Covid-19 sufferers can be carried out. Users of this application will also get notifications if they are in a crowd or in a red zone, namely areas or sub-districts where it has been recorded that there are people infected with Covid-19 positive or there are patients under surveillance. Based on the reviews submitted by users, there are still deficiencies in the application related to user experience. Therefore, it is necessary to improve the interface as an element of the user experience. The purpose of this research is to improve the user experience of the method-based PeduliLindungi application User-Centered Design (UCD). The research phase begins with an evaluation usability use System Usability Scale (SUS), then the interface is improved using the UCD method where the results of this interface design are re-evaluated using SUS. The UCD method can increase user comfort when using applications because of the user's direct involvement in the application development process. The SUS method is applied to see user satisfaction with the application. From the results of testing the PeduliLindungi application, an average score of 51.75 was obtained acceptability ranges or user acceptance shows "Marginal Low" meaning user acceptance of the system is still low. Furthermore, with improvements based on users referring to the Material Design Guideline, problems, and user suggestions show an increase, namely to 83.87 with acceptability ranges or user acceptance shows "Acceptable". It shows the design of solutions using the UCD approach can improve usability by 34%.
