dc.description.abstract | One of the environmental issues that has been always occurs every year is the issue of air pollution. The causes of air pollution can come from both human activities and natural activities. Carbon monoxide (CO) and Carbon dioxide (CO2) are types of pollutant gases that are harmful to the environment. CO and CO2 gases are produced due to the burning process of fossil fuels. In addition to reduce the concentration of CO and CO2 gases in the air, carbon capture technology has the potential as one of the mitigation measures. One of the carbon capture technologies is to use bioreactors. In this study, a bioreactor was used to obtain the concentration values of parameters (CO, CO2, HCHO, TVOC, PM2,5, PM10, temperature, pH, and lux), as well as biomass weight. The biomass of microalgae in treatment 1 is in the range of 0,012 g/ml−0,048 g/ml. The biomass of microalgae in treatment 2 is in the range of 0,011 g/ml−0,031 g/ml. The biomass of microalgae in treatment 3 is in the range of -0,006 g/ml−0,069 g/ml. As for treatment 1, the average absorption capacity of CO was in the range of 8,776%−48,474% and CO2 is in the range of 0,76%−23,36%. In treatment 2, the average absorption capacity of CO was in the range of 9,382%−49.972% and CO2 is in the range of 1,094%−19,463%. In treatment 3, the average absorption capacity of CO was in the range of 33,366%−65,221% and CO2 is in the range of 0,580%−0,975% | en_US |
