Monitoring Covid-19 patients is extremely challenging due to under-resourced or risk of infection. With the increased demand for hospital beds and the difficulty of delivering care, some health centers have advised individual with milder symptoms to stay home. Hence, this paper presents a health monitoring system based on IoT that helps the medical staff to monitor blood saturation, heart rate, pulse rate and body temperature remotely. A Biosensor Module MAX3100 is used to read blood saturation level and heart rate of the patient while body temperature sensor, DS18B20 is employed to scan the body temperature. The measurement of room temperature and humidity level is done through humidity sensor. ESP32 Arduino will encode and decode all input data before execution process. The patient's fingers are connected to the sensors and the data is displayed on the smart phone or PC. The proposed system was tested and provide the intended output. Therefore, with the aid of this proposed system, medical staff can examine and keep track on several patients' status simultaneously and without the hassle of being infected by the virus as it is monitored remotely.
Geocoding is a common technique to transform address information into digital latitude/longitude format. One of the engineering conversions can be used is Google Maps based on S2 (Spherical) Geometry Library algorithm. This journal explains the quality analysis of the algorithm using geocoding quality matrix testing from hundreds of address data samples particularly on three cities in Indonesia-Jakarta, Bandung, and Balikpapan. However, the result of this research concludes that completeness of address information will affect its overall fourth matrix quality and the linkages of it such as transform success rate, landmark exactness, the score of accuracy and range of radius in meter.
The outbreak of the covid-19 virus has caused many listing and funding companies to go bankrupt. J-trus group is one of the companies that has experienced the impact of covid 19, so that the company is able to survive, the company is looking for other ways to get additional income, namely by expanding the sale of basic necessities online, here the author provides a solution using a web-based application to realize this the. So the purpose of this paper is to design and build a PHP-based application with the Codeignither framework. The method uses the waterfall and the database uses a MYSQL database. The design includes Use Case Diagrams, Activity Diagrams, class diagrams. Testing the application with the Black Box testing method, functionally has been declared successful. And based on the test results using the System Usability Scale (SUS), a score of 71 has been obtained with a value above the average so that it can be accepted by users
The benefits of a web-based application make web developers improve the quality of their applications, one of which is implementing a Progressive Web App (PWA). Researchers see the potential of web-based summative test applications at Jakarta Global University (JGU) which have been designed by previous researchers to be developed by implementing PWA. This study aims to develop a web-based online summative test system/application to be PWA-based. PWAs combine the best of the web with the features native apps already have. The benefits of this research can be used as input or reference for JGU in developing more optimal web applications for campus needs. The development in this system applies the public server and PWA methods. Unified Modeling Language (UML) for system design. PWA testing using the Lighthouse tool. The results obtained from this study are in the form of a PWA-based online test summative system with the ability to be accessed on desktop and mobile and the ability to be accessed offline.
