Abstract

This study is aimed to evaluate and access the growth rates and biomass productivity in different concentrations of microalgae Scenedesmus sp. using Industrial Meat Food Processing Wastewater as a media. The focus of this study is to determine the best concentrations of microalgae Scenedesmus sp. in raw wastewater in terms of kinetics of cells growth rates. The study verified that concentration of 1×10⁶ cells/ml of microalgae gives the highest specific growth rates of biomass at 0.4488 day-1 and 1720 cells/ml/day compare to the other concentrations, while the lowest occurred at concentration of 1×10³ cells/ml at 0.4108 day^-1 and 14.9 cells/ml/day. The result shows the different concentration of microalgae Scenedesmus sp. culturing in Industrial Food Processing Wastewater influence the cells growth of biomass and the optimum were obtained at concentration of 1×10⁶ cells/ml which suggested use for Industrial Meat Food Processing Wastewater Treatment purposed. With this finding, it should be seemly to adopt and applied efficiently in treating the wastewater especially for Scenedesmus sp. type of microalgae.
