The Ten November Institute of Technology (ITS) collaborates with Airlangga University Hospital (RSUA) to continue to produce innovative technology for handling the Corona virus outbreak. This time, the invented innovation is in the form of Ultra Violet ITS - Airlangga (VIOLETA) robot which is useful to facilitate the process of room sterilization for the care of Covid-19 patients. ITS Deputy Rector IV, Bambang,Pramujati PhD explained that the idea of creating the VIOLETA robot began when several ITS lecturers succeeded in researching the use of UV light to eliminate or inhibit the growth of microorganisms. This robot can also avoid physical contact with UV exposure because it is very dangerous when it comes to humans directly.
VIOLETA uses a UV light that is controlled remotely by using wireless control. This robot is effectively used at a distance of 1 to 2 meters to the object and takes 10 to 15 minutes to fully sterilize. One of the VIOLETA's research teams, Endarko added that in general, these UV lights have wavelengths of 200 to 300 nanometers. In practice and theory, the wavelength range can kill microorganisms well. This 30 watt UV light is healthier and safer than using disinfectants. This is because there are no residues left after the sterilization process.
As for the application in the Covid-19 case, the VIOLETA robot has the benefit of being able to sterilize the isolation space that has been used or the area that has been used in handling Covid-19 and without involving humans directly. One of the VIOLETA robot team programmers, Achmad Zidan Akbar said, the robot which weighs 30 kilograms uses the basic platform of the ITS soccer robot named IRIS. The VIOLETA also uses an inverter to convert the direct current from the battery into an alternating current which will turn on the UV light.
