Abstract

Bieby Voijant Tangahu

Growth rate measurement of Scirpus grossus plant is conducted to know the growth characteristic. By knowing the growth characteristic of plant, it can be decided the exact time of the fastest growth of plant. Growth rate of plant can be measured by physical parameters such as stem height, number of leafes, leafes lenght, root lenght, wet weight and dry weight of plant. The aim of this study is to observe the growth characteristics of Scirpus grossus plant, which is need to apply the plant in wastewater treatment using reedbed system. By knowing the growth characteristics of plant, will be choose the exact age the plant that is match to be used in the experiment. Besides, it also can be used as a compartment physical indicator that shows the abnormality of Scirpus grossus plant which is exposing to wastewater. The steps conducted in this study are propagation plant to get second generation of plant which is observed its growth rate on stem height, leafes height, and number of leafes, root height, wet weight and dry weight.
