Abstract

Bioaerosol is dust particles consisting of bacteria and other fungi with spores that are in the room when the temperature and humidity level are adequate. Its presence in the room are generally harmless, but some time causes disease. This research was aims to determine the effect of ornamental plant Aglaonema sp., Dieffenbachia sp., and Spathiphyllum sp. on amount of bacteria and fungi in the class room. Bioaerosol isolation was performed according to the method of air sampling with three repetition before and after the plant placed on three classrooms. Plants Aglaonema sp. potentially the most effective in reducing the number of bacteria aerosols from the first week to the third week, whereas for fungal colonies do not show a reduction. The number of bioaerosol were found still in accordance with three quality standarts of Menteri Kesehatan Republik Indonesia. Bacteria found in this study were Streptococcus, Staphylococcus, Bacillus, Pseudomonas and Shigella, while from fungi were Aspergillus, Penicillium, dan Neurospora. Some species of the genus are found potentially pathogenic.
