  We study the electronic instabilities of the Hubbard model in the 1/6
hole-doped Kagome lattice using the variational cluster approach. The 1/6 hole
doping is unique in the sense that the Fermi level is at the von Hove
singularity and the Fermi surface has a perfect nesting. In this case, a
density wave is usually realized. However, we demonstrate here that the chiral
$d_{x^{2}-y^{2}}+id_{xy}$ superconducting state is most favorable when a small
Hubbard interaction U(U<3.0t) is introduced, and a scalar chiral spin order is
realized at large U(U>5.0t). Between them, a spin-disordered insulating state
is proposed.
