Design and Implementation of a Registration System with Mobile Application at Public Health Center Based on IoT Using a RESTful API

In the health service center, many people often meet in a queue and tend to be chaotic, causing uncomfortable conditions and time inefficiency. From these problems, it was thought that technology was needed to make it easier for users to register and monitor queues. In previous studies, we have successfully implemented a digital queue system using a mini PC as the main control. This system has been implemented at the public health center “Puskesmas” Bojong Soang, Bandung. However, the mechanism of queuing, registration, or ticketing and monitoring could not be done online in an application. Therefore, in this study, an Android-based application was developed to register and monitor queues online and in real-time. The main purpose of this study is to build an integrated system between existing queuing machines and mobile applications so that the queuing mechanism can be done online. The proposed system consisted of three main components, namely the digital queue machine, server-cloud, and client application in the user’s smartphone. All modules were connected via the cloud with the developed protocol. This application was called “Q-Puskesmas”, which could run on the Android mobile platform with a minimum version of 5.0. The proposed system is able to display location identity, the latest queue number, and a menu for registering. From the test results, the application can update the queue number in real-time according to the existing conditions with a delay of <150 ms and also print a virtual registration number. This developed application was expected to facilitate the public in using health facilities/services.
