Investment Project Analysis in the Crusher Replacement Plan

Abstract

The global coal market experienced three turbulent years, with a sharp decline in demand during the Covid-19 pandemic, followed by a rebound in demand post-Covid and after Russia's invasion of Ukraine. In 2022, global coal demand reached an all-time high of 8,415 million metric tons, driven by growth in China and India, and continued to rise slightly by 1.4% to 8,536 Mt in 2023. The downward trend in coal prices poses challenges for mining companies, including PT Berau Coal Site Binungan Mine Operation (BMO). This study aims to address the frequent breakdowns of the CR12 crusher at BMO, which result in increased maintenance costs, production downtime, and reduced overall efficiency. Using Total Cost of Ownership (TCO) calculations and the Discounted Cash Flow (DCF) method, the Net Present Value (NPV) of several secondary crusher brands—Joy (existing), MMD, and Shumar—were compared. Results show that Joy has an NPV of -$5,822,030, MMD has an NPV of -$4,527,456, and Shumar has an NPV of -$2,559,450. The negative NPV indicates total costs, where a smaller NPV is preferable. Incremental calculations show that MMD has an NPV of $1,294,575, and Shumar has an NPV of $3,262,581. Based on this analysis, Shumar was selected as the replacement for the CR12 crusher due to its low NPV and cost efficiency.
