Indonesia emitted approximately 692.2 million tons of carbon dioxide in 2022, mainly from coal fired power plants, which also generate large amounts of fly ash and bottom ash. The results show that four photobioreactor units with a capacity of 300 liters each produce 18 kilograms of microalgal biomass per month and capture 32.4 kilograms of carbon dioxide per month. Biofuel production reaches 4.14 liters per month, equivalent to 40.16 kilowatt hours, while the photovoltaic system generates 192 kilowatt hours. it also produces about 4.2 kilograms of  carbon brick material and achieves an energy surplus of 68 kilowatt hours per month.
