Abstract

Production and consumtion oxygen in water ecosystem main problem because of plant respiration, animal, bacteri and other organism.acuatic plant efective that si hypothesized capable in increasing oxygen level throug photosynthesis.But aquatic plant is wear potential bigger oxygen respiration. The aim of study production and consumtion is measure Hidrilla verticillata Royle, Ceratophyllum demersum, Eicchornia crassipes Solm, Salvinia molesta All. This experiment was to understand production and consumtion of plants and species study potencial to supplay oxygen in the water. This experimentwas designed using Complete Randomized Desingned (CRD).This result is rate of oxygen production highest is Ceratophyllum demersum 0,9 mg/L, while lowest rate oxygen negative is Salvinia molesta – 0,58 mg/L is species no oxygen production water, but consumtive water oxygen.Greates oxygen consumtion is Hidrilla verticillata royl 1,43 mg/L, and lowest is Ceratophyllum demersum 0,12 mg/L. Aquatic species plant potencial oxygen production is Ceratophyllum demersum , much oxygen production and some oxygen consumtion
