On the surface of a neutron star, a significant particle density changes can produce charge separation in the form electric dipole layer. This research studied electric field effect from dipole layer on the properties of neutron star. We use two models with different assumptions: namely a model assumes the neutron star only composed of p, n, e and Âµ and a model which assumes the neutron star is composed of p, n, e, Âµ dan hyperon. The result showes that the maximum mass is not sensitive to the electric field on the surface, but the radius of star with canonical mass 1,4 MÊ˜ is quite sensitive to the electric field . The neutron star with hyperon is softer than without hyperon.
