The purpose of this study is to investigate the ability of coontail plants (Ceratophyllum demersum) to produce oxygen gas which is used for the survival of aquatic biota and to determine the effect of temperature and intensity of sunlight in photosynthesis. The method used in this study is the Ingenhousz method with three sets of devices that are given different treatment that is placed in an open space, a closed room and using water that is heated at a temperature of 40 ° C. The number of oxygen bubbles with the highest yield was at a treatment temperature of 40 ° C, 30 bubbles in 40 minutes. Coontail plants are best used as phytoremediation agents because these plants have quite good photosynthetic abilities to maintain the survival of aquatic biota.
