<![CDATA[Indoor air pollution is a crucial thing cause it will affect for human health. One of the things that can be done in indoor air pollution to control indoor air pollution by using plants, namely Sansevieria trifasciata which is Green Tiger sp. This research is done in order to identity the absorption the level of Sansevieria to reduce carbon monoxide pollution. The research used pre-experimental design through the analytics of One Group Pretest Posttest. Statistical analysis using paired t – test. The level of carbon monoxide pollution were decreased after being treated by Sansevieria, which is from 64.27 ppm ± 11,87 and 42.06 ppm ± 12,68 and the results of the Paired t-test showed that the value of P namely 0.01 or P 0.05. Therefore, the utilization of Sansevieria in the room is needed to reduce carbon monoxide pollution, also furtter research future research is needed to be done. ]]>
