| dc.description.abstract | The use of the mask is one of the most effective efforts to prevent the spread of dangerous viruses such as Covid-19. The masks themselves have many types, one of which is a medical mask, this mask uses a filter that can prevent harmful substances in the air. Masks have a type that can protect depending on the level of danger from exposure to hazardous particles in the air. This research was conducted using an experimental method in which the process of measuring the penetration power of particles with variations in distance and variations in the source power (lamp) using a lux meter with the steps (1) Preparation of the tool. (2) Pipe connection. (3) Installation of the LED light. (4) Installation of samples (masks). (5) Measurement of light intensity. (6) Data analysis. The result of the research carried out has obtained superior masks from 5 variations of masks that have been tested, namely filtered cloth masks which have an intensity value of 0 and there is no increase | en_US |
