Optimization of Profitability Based on Using Percentage of Total Float in the Project Implementation Schedule

A construction project can run well if they have efficiency in terms of time, cost and, resources. This research aims to determine optimization of the percentage of total float use to optimize project profitability, by looking at the highest Net Present Value (NPV), Return on Investment (ROI), and Benefit Cost Ratio (BCR) with a case study of the construction of a 12-story building in Surabaya. The variations used in this study include Total Float values ​​of 0%, 25%, 50%, 75%, and 100%. Based on each variation, it will produce different work weights and payment terms which will then be used for financial analysis to calculate BCR, ROI, and NPV on each cash flow to assess the optimization of the use of total float in this study. From the results of the discussion, known that most optimal cash flow planning is in scheduling conditions with the utilization of a total float value of 75% with an NPV value of Rp 7,037,643,148. with a BCR value of 1,09228 and an ROI value of 9,228%.
