Abstract

The growth of the human population causes an increase in pollution generated because of the activities carried out. One of the causes is from the vehicle fuel used with the resulting exhaust gases that can cause global warming. From the fuel problem, there is an alternative solution through fuel from the bio-mass of living things or known as biofuels. The great potential of the material used as a biofuel is the microalgae Chlorella sp. because of the amount of lipids that reach 20% of the total dry biomass. Through hematite nanoparticle supple-mentation, Chlorella sp. microalgae can be accelerated in growth and lipid production. The research conducted obtained the results that the best concentration of hematite nanoparticles for lipid production for Chlorella sp. microalgae was 3 g/L. This concentration is 17 g of lipids and from the Luedeking-Piret model it is obtained that 20% of lipids are produced along with biomass growth. So that the lipids produced from microalgae Chlorella sp. have great potential to be processed into biofuels as a nature-based solution for sustainable vehicle fuels.
