  The analysis for the strange and multi-strange hadrons production is
presented for proton-proton (pp) collisions at $\sqrt{S_{_{NN}}} =$ 200 GeV as
reported by the PYTHIA 8 event generator simulations. The strangeness
enhancement is studied in details at $\sqrt{s_{_{NN}}} = $ 200 GeV in
proton-proton (pp). We preform the transverse momentum distributions for high
and low multiplicity events of the strange and multi-strange hadrons. Here we
present the observation of strangeness enhancement in pp collisions for
$K_{s}^{+}(u\bar{s})$, $K_{s}^{-}(s\bar{u})$, $\Lambda^{0}(uds)$,
$\Xi^{0}(uss)$, $\Xi^{-}(dss)$, $\Omega^{-}(sss)$ production. At the RHIC
energy, the strangeness content yield increases with the event multiplicity.
