The research aimed to measure the effectiveness of Azolla microphylla in reducing petroleum hydrocarbon in brackish water. A completely randomized design was used with two factors: pollutant concentration (factor A) and A. microphylla addition (factor B). A consisted of A1 (10 ppm), A2 (20 ppm), A3 (30 ppm), A41 (40 ppm), and A5 (50 ppm). B consisted of B1 (50 g) and B0 (0 g of A. mycrophilla). The experimental units contained 10 L of water planted with fern (50 g) and control (B0). Analysis of variance shows that A. microphylla has a significant effect on the reduction of petroleum hydrocarbons in brackish water. The plant reduced levels of this pollutant by up to 36%. Without A. microphylla plants, the pollutant was decreased to 14-22% only. The pollutant reduced the leaf chlorophyll of the fern to 39.5%. The higher the pollutant level, the lower the chlorophyll content.
