Eka Maulana bersama mahasiswa Teknik Elektro UB merakit Plasma Ozon dalam bentuk chamber

Since the outbreak of the COVID-19 virus, sterilization has often been carried out using various methods. Lecturer at the Faculty of Engineering, Universitas Brawijaya (FTUB) Eka Maulana, S.T., M.T., M.Eng., presents a more practical and effective alternative sterilizer, the Plasma Ozone Sterilizer.

Plasma Ozone Sterilizer is a non-contact sterilizer with ozone generator and ultraviolet technology based on high voltage technology to kill bacteria, viruses, fungi, and other pathogens.

This innovation can be applied in various spaces; medical rooms, academic rooms, public facilities (terminals, stations, airports, etc.), public rooms (malls, hotels, apartments, etc.), as well as special rooms (homes, offices, industries, etc.).

Not only space, sterilization can also be done on items that interact directly with living things. From kitchen utensils to pets and plants.

“And what’s special about this innovation is that it can also sterilize waste,” Eka explained.

Plasma Ozone Sterilizer, he continued, can be made according to needs. Can be shaped like an air conditioner, hand dryer, or chamber.

“The shape is flexible, can be adjusted according to the needs of the room,” this Electrical Engineering lecturer said.

How the Tool Works?

The method used in this system is by flowing air in a certain room and processing it in a chamber using a plasma generator and UV treatment.

Clean air that has been sterilized and contains ozone is flowed through a pipe at the top of the room continuously.

“Air is flowed through plasma (which is generated from a high voltage generator) and also through UV treatment so that it is layered. So that air, even from garbage or from waste, can be sucked up and removed with the addition of ozone gas. This is what we called, double treatment,” he explained.

Eka emphasized that Plasma Ozone Sterilizer does not damage the environment. In addition, the way it works also does not create air circulation like AC which can makes ones infected just by being in the same room.

“The tool will immediately suppressed the growth of pathogenic microorganisms, be it viruses, fungi, algae, or bacteria,” he said.

It can also detect the user’s presence in the room. Within a few seconds this tool works to absorb air at the inlet which is located at the bottom, while the sterile air containing ozone is flowed through the air outlet at the top.

“This tool can be operated for sterilization rooms, entrance gates, and cleaning industrial equipment from pathogenic microorganisms that damage and disturb human health quickly, safely ,and effectively,” he said.

Not only those above, this tool can also be operated automatically and monitored by a smartphone or computer device via an internet network connection.

“To see the status is on or off, how many times a day is active, this can be monitored,” he added.

Solutions for Waste/Medical Waste Sterilization

Plasma Ozone Sterilizer can also be designed for the sterilization of medical waste. Eka explained, viruses/bacteria in medical waste must be turned off or lysed before being disposed of so that they do not damage the environment.

“So the direction is actually for medical waste. “It should be processed first so that existing viruses do not spread again,” he said.

He added that currently there is no medical waste processing in Malang. Usually it must be sent to Mojokerto. Meanwhile, in the shipping process, waste is certainly prone to contaminating many things during the expedition.

“So ideally every hospital or clinic or any health institution should carry out early treatment waste with this system so that the virus dies before it is transferred to the medical waste processing place,” he said.

Not only that, Plasma Ozone Sterilizer is also effective for installation in public places such as cafes where there are many people. It’s just that, the aroma may be more distinctive and oxidative.

“Not as dangerous as air conditioning. But the risk is that there may be corrosive to uncoated iron,” he added.

Eka hopes that the results of this innovation can be used for the sterilization process, at least to minimize the spread of harmful viruses/bacteria.

This treatment system is relatively safe compared to the existing sterilization systems and is effective because the resulting air gusts can enter between parts that are not on the surface. Thus, it is hoped that the number of covid-19 spreads can also be minimized.

“It is hoped that this tool will not only benefit individuals but also society in general,” this alumni of Japan Miyazaki University concluded. (malangtimes/mic)
