A magnetic field can accelerate its reaction by decreasing the frequency of reverse reactions in the radical pair mechanism. The effect of magnetic field (MF) changes the rotational dynamic of the radical pair and in general alters the yield and lifetimes of its product. The external magnetic field applied to the system causes a radical pair reaction change. This phenomenon can be explained by a rate constant K 3 for dual-reaction coordinate movement or triplet state formulation and according to the effect of the function rate dependent on magnetic K ISC . To achieve a desired magnetic effect on the system, state that the of K 3 and   rates must be equally large to observe the effect of the magnetic field on the reaction rate. In systems with forward reaction rate at  3 >>  , the modeling result indicates that the maximum rate of effectiveness, (  ) is likely to occur at ≈7.85 militesla with (  ) value at 2.63x10 -10 second. As simulated into the system, the MF influences reach at peak values of between 7.25mT (6.24 x 10 -9 second, reaction rate) to 8.25mT (3.94 x 10 -10 second, reaction rate). The significant result of the MF influences towards the microalgae growth production is indicated the range of 110 -10 to 7.75 militesla is observed to have influence on the rate of (  ).

INTRODUCTION n algae photosynthesis, lights are transferred into chemical energy via photo induced electron transfer reaction. The whole process consists two consecutive: Light and dark phase. The light reactions include light absorption, transfer of excitons, and electron and proton translocation resulting in the production of NADPH2, ATP, and oxygen. In the light phase, a photochemical process occurs, transforming the photon energy of solar radiation into chemical energy. At first, the energy of the radiation is converted into the energy of the excited electrons, which is converted by oxidoreductase to macroergic compounds - ATP (adenosine triphosphate, source of chemical energy) and NADPH (nicotinamide adenine dinucleotide phosphate, reducing agent). The light reaction is due to the photosynthetic apparatus experiences sequences reaction as refer to photoreceptors that contain radiation-absorbing pigments, photosynthetic reaction center, where light energy is converted into electrical energy (= electron excitation by absorbed radiation) and string oxidoreductase, where excited electrons are converted to chemical energy (formation of ATP and NADPH) [1]. The reaction centre itself is composed of the two intrinsic polypeptides D1 (psbA) and D2 (psbD). D1 and D2 form a heterodimer and bind a variety of photochemical components such as chlorophyll P680, pheophytin, tyrosine YZ, and plastoquinone I
