Abstract

The number of people confirmed positive for Coronavirus Disease 2019 (COVID-19) in Indonesia reached 605,243 people as of December 11, 2020, of which 18,511 people died. COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) which can spread rapidly through droplets and is viable under certain conditions. On the other hand, the Ministry of Education and Culture of the Republic of Indonesia plans to allow face-to-face lectures starting in January 2021. Of course this requires strict health protocols and facilities that support learning activities without increasing cases of COVID-19 transmission. Therefore, in this paper an innovation is designed in the form of a smart classroom consisting of a sterilization system based on ultraviolet C (UVC) light with a wavelength of 254 nm. Smart classrooms are also equipped with a security system in the form of automatic locks, contactless sensors for opening and closing doors, automatic lighting, and a real-time Internet of Things (IoT) based monitoring system. In this paper, a system simulation is carried out using Tinkercad and the Thingspeak web server. The sterilization process is designed to be carried out for 30 minutes with a UVC dose of 220 J / m2. For a classroom with an area of ​​64.17 m2, a dosage of 14,117.4 J is needed, so it takes 2 Philips UVC TMS030 1xTUV T8 18W HFP which has an irradiation of 0.09 W / m2.
