ii ABSTRACT DESIGN AND IMPLEMENTATION PROTOTYPE OF IOT CLOUD SERVICE DEDICATED FOR MEASURING URBAN HEAT ISLAND SENSOR DEVICES By Josua Dion Tamba NIM: 23219325 (Master’s Program in Electrical Engineering) Urban Heat Island is a phenomenon characterized by urban areas that have hotter air than rural areas. This phenomenon can be caused by many factors. There are two ways to observe this phenomenon: indirect and direct measurement. Direct measurement by measuring at observation points such as mobile measurements and fixed stations. Measurements with the fixed station can produce data from time to time at one observation location. The implementation of this method can use the IoT concept, the results of the latest research show that in this way the UHI value can be calculated periodically and automatically. From the literature review results, the author has not found a system for device management and measurement dedicated to UHI. Therefore, the authors designed a cloud service that provides device management services and measurement data, also data access management for further analysis. Interaction on this system is through a website app so that it is easily accessible through a browser. The results of the analysis of problems and needs describe the points that must be overcome and then design the system architecture. Tests were carried out by simulating 2 groups of devices, with 6 and 8 devices respectively. Also testing the response time of data retrieval without Redis is 52464.02 ms and with Redis is 27978.47 ms. Then the results of the design are tested for their functions, and the results are that this system can work according to the design. Keywords: Urban Heat Island, fixed-station, IoT Cloud-Service
