Abstract

Methyl orange dyes are often used in industrial activities and produce wastewater that can pollute the environment. One of the plants that usually live in water and usually used phytoremediation is pistia plan. This study aimed to determine the acute toxicity (LC-50) of pistia plants in methyl orange wastewater. This study consisted of two stages, acclimatization and range-finding tests. The reactor used in the study has volume 5 L. The detention time in determining acute toxicity for pistia plants is 30 days. The acclimatization stage for seven days showed a profitable growth in the pistia plant. The LC-50 value in pistia plants showed a value of 58.73 mg/L. Knowing the LC-50 value in pistia plants is
used as a standard reference for wastewater treatment containing methyl
orange into the waters. The lethal concentration (LC-50), which can kill
50% of the pistia plant, is 58.73 mg/L.
