This study aims to analyze the growth of microalgae Chlorella pyrenoidosa cultured in the medium from a tofu wastewater area treatment. The study used an experimental method with 4 treatments and 3 replications. The treatments were carried out by administering different concentrations of tofu wastewater to C. pyrenoidosa. The concentrations used were 10%, 15% and 20% with a light intensity of 5000 lux. The main parameter observed was microalgae growth, while the supporting parameter was water quality, which affected the growth of C. pyrenoidosa. The results indicated that different tofu wastewater treatments produced different densities of C. pyrenoidosa. The highest density of C. pyrenoidosa was found in the tofu wastewater treatment of 20% (3.253x104 cells mL-1 ). The ranges of temperature, pH and dissolved oxygen from the culture were 27.4-28.5°C, 7.1-8.76, and 6.9-8 mg L-1, respectively. The analysis of variance (ANOVA) test revealed that different concentrations of tofu wastewater can affect the density of C. pyrenoidosa. The most significant differences were observed in the concentration of 20%. Moreover, the present study suggests further research on conducting semi-continuous cultures of C. pyrenoidosa with tofu wastewater treatment. © 2020, BIOFLUX SRL. All rights reserved.
