ALAT STERILISASI UDARA DILENGKAPI SINAR UV DAN HEPAFILTER DENGAN KONTROL MENGGUNAKAN APLIKASI BLYNK

In a room there are microorganisms suspended in the air. The size of the cells of these microorganisms is usually very small and can be blown by air. Its spread will affect the room so that the room must be kept sterile. Therefore, this research will design an air sterilizer with UV light and a Hepafilter with control using the blynk application which is used to sterilize the air contained in a room to keep it clean from microorganisms. This tool is equipped with a UV lamp and a hepafilter that can be controlled using push button and blynk application on smartphone. The tool will suck the air contained in the room using a blower, then the air will be sterilized using UV light and a hepafilter. From the test results, there is a decrease in the number of particles before and after sterilization, when the blower is set in the high position, the number of particles decreases by ± 5000 for 30 minutes after the sterilization process, when the blower is set in the medium position the number of particles decreases by ± 2000 for 30 minutes after sterilization process, and when the blower is set to a low position, the number of particles decreases by ±1000 for 30 minutes after the process. It can be concluded that this tool can be operated automatically using the blynk application and manually, because sending data from blynk to the tool will cause a delay of ± 0.5 seconds in operation, the faster the blower and the longer the sterilization process is carried out, the faster the particles will be reduced
