Abstract

Microalga is single cell organism that can live by photosynthesize resulting biomass and other secondary product such as protein, carbohydrate, and fat by utilizing nutrients under appropriate environmental condition. Microalga can be used to processing liquid organic waste in order resulting safer effluent and easily neutralized by the nature. These study is aiming to get the data about the effect of gradual additions of tofu liquid waste to the growth and increase of lipid content in the microalga that cultivated in tofu liquid waste media. Microalga were cultivated by variations in gradual media adding. The variations are 0.45 liter in every day, 0.9 liter in every two days, and 1.35 liter in every three days. Microalga growth were measured by an object glass, the amount of cell density in every square field calculated using tomacytometer by aiding of hand counter where observed under light microscope. Total lipid content were gained by employ Bligh-dyer methode. The results of this study show the highest specific grow rate of Chlorella sp is 0.08692/day accounted from gradual tofu liquid waste addition in every three days. The highest lipid content is 40.879 % which gained from gradual tofu liquid waste addition in every day. Under unfavourable condition microalga will accumulate more lipid so that increase lipid content of it’s self. The highest chemical oxygen demand (COD) removal is 575 mg/mL.
