Abstract

Capital resources play an important role in a project. The optimization of working capital effectively and efficiently can have a major effect on achieving the maximum profit value for the contractor. Therefore, controlling cash flow is very important. One alternative that can be used to obtain maximum profit is the right scheduling. This study aims to plan scheduling optimally using the Ms.Poject ap`plication by utilizing float time. Where the utilization of float time uses a scheme with  25% down payment and without down payment. The float time variations used are 0%, 50% and 100%. An economic feasibility analysis was conducted to review the NPV, BCR, and ROI values. From the analysis results, the greatest profitability was obtained in the alternative without a down payment using 100% float. With an NPV value of Rp16,164,849,630, BCR value of 1.0651, and ROI value of 6.51%. It can be concluded that this alternative has maximum profitability.

Abstract

One of the important elements in the construction process is lightweight brick work. Labor productivity in this work is very influential on the progress of the construction project as a whole. One method that can be applied to analyze labor productivity is work sampling, which is an observation method used to measure and analyze the productivity of workers or activities at a certain time. This study aims to investigate and analyze labor productivity of lightweight brick work labor. The work sampling method was chosen to analyze the productivity and quantity of labor in lightweight brick work on the Bekasi Mixed Use Development Pakuwon Residence project. Based on the analysis and discussion during the 10-day observation period, 8 lightweight brick masonry workers completed work with a total area of 658.480 m2 and obtained a productivity value of 52,730 m2/day. In addition, from the results of field observations, the level of worker adjustment factors and allowances can still be increased, with the hope that this increase will significantly increase worker productivity in terms of time, quality, and quantity.
