ANALISIS KARAKTERISTIK TANAMAN SANSEVIERA DALAM MELAKUKAN PENYERAPAN GAS BERACUN PADA RUANGAN TERTUTUP

Indoor air quality needs special attention because it is very influential on human health. One way that can be done is to keep the indoor air quality clean by utilizing sansevieria trifasciata plants. This study aims to detect air pollution levels in a closed room containing the Sansevieria Trifasciata plant The results showed that sansevieria plants could absorb CO gas perfectly compared to ivory betel plants. This is evidenced by the level of effectiveness and efficiency in absorbing CO gas where the sanseviera plant is able to absorb CO gas by 54% in 75 minutes compared to the ivory betel plant which is only able to absorb CO gas by 20.57% in 85 minutes.
