Application Of Sansevieria Sp Sp And Cymbopogon Nardus Extract Formula As Control Of Mould And Germ Numbers In The Air With The Humidifier Method

Abstract

The purpose to be achieved is Analyzing Sansevieria sp sp and Cymbopogon Nardus Extract Formula as Control of Mould and Germ
Numbers in the Air with The Humidifier Method. The experimental design used in the study was the One Group Pretest Posttest
Design. The independent variables were extracts of Sansevieria sp and Cymbopogon Nardus with concentrations of 50%, 60% and
the dependent variable was the number of moulds and numbers of germs. Analysis of the data used in the form of the Mann
Whitney test. The results showed that the average number of airborne germs in the room before being treated with a
concentration of 50% and after being given treatment there was a decrease of 86.64%. The 60% concentration treatment
decreased by 87.35%. Meanwhile, with the number of air moulds in the room before being treated with a concentration of 50%,
after being given treatment there was a decrease of 80.34%. Likewise, the average number of air moulds in the room after being
treated with a concentration of 60% decreased by 85.45%. From the results of statistical tests, it was stated that the extracts of
Sansevieria sp and Cymbopogon Nardus with concentrations of 50% and 60% had the same ability to reduce the number of germs
and the number of moulds Room air. In conclusion, the germ numbers and numbers of room air mussels before and after exposure
to Sansevieria sp sp and Cymbopogon (Pasqua et al., 2018)
