The research method used includes three main parts, namely literature study, observation of similar applications, and surveys. Literature study includes four main parts, namely literature study, observation of similar applications, prototyping, and evaluation. Literature study includes reading and studying books, previous theses, literature related to the topic, and drawing conclusions from all references. Observation of similar applications is carried out by observing several similar applications that have similar functions and analyzing the advantages and disadvantages of each of these applications as a reference. A working application prototype is built based on the prior requirement gathering. The evaluation was conducted using the System Usability Scale survey which is carried out by providing an online form to the public. The results achieved from this study based on the reliability test show that this research instrument is reliable or trustworthy.
