A feasibility to use the hadronic decay mode of Z for the model independant measurement of the total cross section of Higgs-strahlung process (σZh) at a future e+e- collider was studied. For the recoil mass measurement from hadronic decay of Z, a simple cut based analysis was applied on samples produced by the ILD full detector simulation at √(s)=350 GeV and 500 GeV using the ILC beam parameters. At 350 GeV, a bump in the recoil mass distribution was reconstructed, and ΔσZh/σZh = 3.4% was obtained assuming 165 fb-1 data with e-(e+) beam polarization of -80%(+30%) and +80%(-30%), respectively. At 500 GeV, clear Higgs boson peak in the recoil mass distribution was not seen, however, from the excess of the events, ΔσZh/σZh=3.9% was obtained assuming 500 fb-1 data with e-(e+) beam polarization of -80%(+30%).
