Studies on Magnetohydrodynamic (MHD) boundary layer flow and heat transfer due to a stretching surface play an important role in many engineering processes and industries. It is proved that the rate of heat transfer influenced the quality of the final product in the engineering process. This research investigates mixed convection on unsteady MHD flow over a stretching surface with thermal radiation effect. The governing partial differential equation is transformed into the system of ordinary differential equations by applying similarity transformation. Then, the transformed boundary layer equation is solved numerically using the Runge-Kutta-Fehlberg method scheme with a shooting technique in the Maple software environment. It was found that the rate of the heat transfer at the surface increase with the presence of the magnetic unsteadiness parameter, A. Meanwhile, the heat transfer rate decrease with the presence of the Buoyancy parameter, λ.
