  Strangeness study is one of the major goal of the STAR experiment at RHIC.
Results presented here have been obtained from analyses restricted to the
mid-rapidity region of Au-Au collisions at $\sqrt{s_{NN}}$ = 130 GeV. An onset
of the understanding of the quark matter behavior produced at this relativistic
energy can be stressed from the investigation of the relative and absolute
yields of strange particle production, their transverse mass distributions and
from comparisons with previous results obtained by AGS and SPS experiments.
