“…An eco-friendly alternative disinfection technique, which does not rely on chemicals, involves the use of ultraviolet (UV) decontamination [7], specifically ultraviolet-C (UV-C) light [8], [9]. The International Ultraviolet Association (IUVA) also releases the fact that UV is capable of inactive coronavirus [10].…”

To prevent the transmission of the coronavirus disease (COVID-19), one approach involves the application of disinfectants containing specific chemical compounds. Nonetheless, an overabundance of chemicals may yield adverse effects on both humans and the environment. Therefore, alternative methods are needed to prevent the spread of the virus without endangering humans and the environment. One method that minimizes the use of chemicals is ultraviolet-C (UV-C) light. The method used in this study is to make a UV-C lamp control system based on the internet of things (IoT). Then conduct experiments on the spread of UV-C radiation using a system that has already been built. Based on the research that has been done, a disinfectant system has been successfully designed using two Philips 30 W UV-C lamps with Wemos D1 mini microcontroller and Blynk application. The results of data collection show that the highest ultraviolet-C radiation irradiation on the intended object is 0.017 mW/cm<sup>2</sup> with a distance between the two is 1.5 m.
