The coastal area in Pekalongan has a big problem of flood that is caused by rain and tidal flood. To overcome the situation, in 2018-2019, a drainage with polder system has been built at Mrican-Wonokerto area, Pekalongan Regency, equipped with the 5 km embankment and long storage. The aim of this study was to acquire correlation model between pump discharge and fuel oil consumption of Mrican-Wonokerto Polder System and to conduct simulation of operational cost from the fuel oil to the electricity provided by PLN. The method used is quantitative method with daily data in the form of pump operation record of Silempeng and Sengkarang pump houses. The analysis results indicated that the equation of the relation between the pumping volume capacity (X) (in m 3 ) and fuel oil consumption (Y) (in liter) of Silempeng and Sengkareng pump house were linear equations. The equations were Y = 0.2509+ 0.0044X with a correlation coefficient (r) of 0.928 for Silempeng and Y = 0.5608+0.0035X with r=0.981 for Sengkarang. The equation of relation between the actual pumping volume and and fuel oil consumption during the absent of rain was Y=0.5292+0.0067X with r=0.8328, while the rainy days was Y= 0.6605+0.005X with r=0.8329. The simulation of change from propulsion of diesel pump machine to electric propultion proofed that the change could generate efficiency 45.12% at Silempeng and 30.53% at Sengkarang pump house in the aspect of operational cost. The results of this study are used to a guidance for pump operational financing by the government.
