Abstract
The calculation of cost estimation that has been done so far in the Office of Public Works and Spatial Planning of Sidoarjo Regency was made based on experience in similar projects in previous years without any specific method, so that can not be identified any work that significantly affects the total cost the project. So that required an estimation method that is considered quite accurate and significantly affect the cost of the project, namely Cost Significant Model. This study aims to determine the components of work that significantly influence the total cost of channel development in Sidoarjo and calculate the estimated cost model of channel development with the method of "Cost Significant Model". The most influential/significant work to the planning of development project per m channel work is stone masonry work, then sequentially are pile work, reinforcement work, and concrete work. The estimated model produced is Y = 71.864,499 + 1,257X1 + 1,235X3 + 0,990X4 + 1,605X5, where X1 is stone masonry work, X3 is concrete work, X4 is reinforcement work, and X5is pile work. With the accuracy of cost estimation of the significant cost of the model between -18,7.0% up to + 10.5%, with an average accuracy of 0.2% and the value of Cost Model Factor (CMF) of 1.0000 then the estimated model obtained very well.
