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
