Objectives: The rate of coronavirus disease 2019 (COVID-19) booster vaccination in Indonesia remains relatively low, representing15.33% of the overall vaccination target as of April 2022. The implementation of a reminder and recall system hasbeen shown to be effective in increasing vaccination rates. In prior research, reminders and recalls were sent through traditionalmedia, such as mail, and had not yet been integrated into modern media, such as smartphone applications and (inparticular) contact tracing applications. Therefore, the present study was conducted to design a reminder and recall systemfor the PeduliLindungi contact tracing application.
Methods: We used the design science research (DSR) methodology withthree iterations. The first iteration produced a low-fidelity prototype (or wireframe), and the next yielded a high-fidelity(clickable) prototype.
Results: The final prototype included three main features: a reminder and recall mechanism, onlineregistration for COVID-19 booster vaccination, and educational articles. The evaluation consisted of interviews in the firstiteration, interviews and the System Usability Scale (SUS) questionnaire in the second, and the Post-Study System UsabilityQuestionnaire (PSSUQ) in the third. The SUS value obtained in the second iteration was 71.6, indicating good (acceptable)results, while in the third iteration, the system usefulness, information quality, interface quality, and overall PSSUQ valueswere 2.456, 2.473, 2.230, and 2.397, respectively, indicating good quality of the resulting design.
Conclusions: This researchcontributes to two areas: implementation of a reminder and recall system in the PeduliLindungi contact tracing applicationand enhancement of contact tracing applications using DSR methodology.
