SMART MICROALGAE PHOTOBIOREACTOR HELPED BY SOLAR ENERGY AS ECO-GREEN TECHNOLOGY TO REDUCE CO2 EMISSIONS IN JAKARTA, INDONESIA

 Global warming that cause climate change effects has become the center of attention around the world to find a solution in order to reduce or minimize its impact. Formerly, Indonesia was an agricultural country. Currently, Indonesia has started become a state-based industries, especially in DKI Jakarta. The impact was increasing CO₂ emissions since the Industrial Revolution. The primary causes are deforestation and the burning of fossil fuels such as coal. CO₂ levels have risen, so have its effects on air pollution. In addition, Indonesia has one of the marine resource can be used to absorb CO₂ is faster than land plants that is Nannochloropsis sp microalgae. Therefore, the Nannochloropsis sp microalgae photobioreactor as eco-green technology will be placed on the rooftop of high buildings. So, it is expected as a potential solution in order to realize a healthy Indonesia 2030. Microalgae photobioreactor was created to find out how much CO₂ absorbed and O₂ produced. This research was conducted among 4 months in State University of Jakarta. The steps were study literature, supply tools and materials, photobioreactor manufacture, due diligence, Nannochloropsis sp cultivation, and CO₂ absorption and O₂ production test. The data obtained between CO₂ absorption and O₂ productivity is directly proportional. In the first, second and third repetitions CO₂ absorption and O₂ production were found at 40%, 68% and 83%. Therefore, microalgae photobioreactor can be one solution to reduce CO₂ emissions, especially city-based industries in Indonesia. So, microalgae photobioreactor assisted by solar energy as eco-green technology can be applied to reduce CO₂ emission trigger global warming that causes climate change effects in city-based industries. This is one of Indonesia’s efforts to gain sustainable green environtment and provide a good impact for public health.
