Abstract

The development of a country's road or toll road infrastructure can be used as a benchmark to judge a country's economic development at both macro and micro levels. The location of toll exits has a significant impact on labor absorption and the creation of new business activities. Projects are dynamic, so contractors must adapt to changing project situations and conditions if they are to succeed in achieving optimal profits. Today's highly competitive aspects of construction planning require high levels of accuracy, efficiency, effectiveness and economy in project analysis. In the world of construction projects, there is much that can be done, including controlling costs. In cost control, efforts can be made so that the realization of costs incurred is consistent with implementation needs and is not excessive, such as efforts to limit costs, that is, to realize savings without does not reduce quantity or quality. The earned value method is used to determine the project's performance in terms of cost at a certain time, determine the project's performance in terms of progress/time at a point in time. certain, estimate the cost to complete the project after the evaluation period and estimate the cost to complete the project after the evaluation period. Project completion time after evaluation. In this study, the author performed a cost analysis using the earned value method for the conservation of Pandaan Malang Section 5 toll road. The schedule variance value is Rp1,652,192,521 with the time performance index value of 1.139743112 or SPI value > 1, meaning this project has arrived at week 17, the implementation is faster than planned.The estimated project completion date or Expected Schedule (EAS) is 278 days, 22 days faster than the total contract period of 300 days.

Abstract

Porous concrete is widely used as a sustainable construction material since it allows water to pass through its structure, reducing surface runoff and supporting groundwater recharge. However, its application is often limited by its low compressive strength. This study investigates the effect of adding superplasticiser at varying dosage levels: 0.3%, 0.6%, and 0.8% of cement weight, on the mechanical properties of porous concrete. The research was conducted through laboratory experiments, with material testing, slump testing, and compressive strength testing at 7 and 28 days of curing. The results showed that the addition of superplasticiser significantly improved the compressive strength of porous concrete without affecting its porosity. The highest compressive strength was achieved at a 0.8% dosage, reaching 23.01 MPa at 28 days, which represents a 21.4% increase compared to normal porous concrete. The slump test confirmed that all concrete mixtures maintained near-zero slump values, ensuring that permeability was not compromised. These findings suggest that superplasticiser is an effective additive for improving the strength of porous concrete while preserving its essential drainage function. The research supports the broader application of porous concrete in sustainable infrastructure, especially in areas where both strength and water management are critical.
