Antibacterial Potential of Freshener Water Based on Siwalan Coir Extract (Borassus flabellifer) and Lemongrass (Cymbopogon citratus) Against Airborne Bacteria

Air is an important part of life. The Quality of air can be seen from three parameters, namely chemical, physical, and biological parameters. One of the biological parameters of air quality can be seen from the presence of microorganisms such as bacteria. The presence of airborne microorganisms, especially in enclosed spaces can affect human health, one of which can cause respiratory infections. On the other hand, people often use air freshener products. Therefore, this research was conducted with the aim of analyzing the potential of air freshener based on siwalan (Borasus flabellifer) coir extract and lemongrass as antibacterial against airborne bacteria. This research is an experimental research with a pre test-post test design. The data obtained is in the form of the value of the Total Plate Count of indoor air bacteria before and after treatment using air freshener based on coir extract of siwalan and lemongrass. The results showed that both formulations (P1 and P2) of air freshener based on coir extract and lemongrass were able to reduce the number of airborne bacterial colonies in the room, with a significance value of 0.000
