ABSTRACT
The implementation of a construction project often results in residual construction materials. Factors that cause residual or waste iron material is cutting that is not optimal. During the cutting process, it can be triggered by an error factor in the preparation of the bar bending schedule or bestat . Therefore, to reduce a large amount of waste, an effort is made to calculate or re-plan the iron demand using the linear. In this method, we can solve an optimization problem of the combination of cutting length of reinforcing steel, by determining the objective function and the constraints. So that in this research, an optimization waste of iron pier of the Jakarta – Cikampek 2 Elevated program linear. The results obtained are that with the linear and the help of the excel solver add-in, it can optimize waste of reinforcing iron-on pier toll road elevated. The total amount of savings on waste is 21.65% and the total savings on the number of iron rods is 23.46%. However, there are no savings in D25 iron, because the results from the waste and the need for iron solver are the same as those in the field.
