Abstract

In Gresik, East Java, a New Sulphuric Acid Plant (NSAP) construction project with a
capacity of 1.350 TPD is underway. However, the project has faced delays due to labor shifts across
different work areas, leading to a decline in project performance. If the project is delayed, the company
faces a penalty of 0,1% per day of the contract value. This study evaluates the performance of the NSAP
project at a copper smelting company in Gresik using the Earned Value method. The Earned Value
method is crucial in managing construction projects like NSAP to enhance control, monitoring, and
efficiency. The project, with a budget of Rp 44.450.000.000, is scheduled to be completed in 13 months.
By the 13th month, the Schedule Performance Index (SPI) was 0,90 (<1), indicating a delay of 9,512%.
The Cost Performance Index (CPI) was 1,03 (>1), showing that the actual cost of Rp 38.896.768.171
was below the budget, making the project more cost-efficient despite the extended timeline. The project
is expected to be delayed by 38 days, with a final estimated cost of Rp 42.985.536.316. After
rescheduling using the PDM method, it was determined that the project could be completed on schedule
without incurring late fees.
