Abstract
Portland Composite Cement (PCC) is a type of cement produced from Portland cement clinker, gypsum, and additional inorganic materials such as fly ash and copper slag. PCC offers several advantages, including lower heat of hydration, higher resistance to sulfate attack, and smoother concrete surface quality. The demand for PCC in Indonesia continues to rise in line with rapid infrastructure and housing development, particularly with the National Capital (IKN) relocation project, creating strong potential for new cement plant establishments to meet domestic needs and reduce imports. The planned PCC plant is scheduled for operation in 2028 with a production capacity of 350,000 tons per year. The plant will be located in Bangkalan Regency, East Java, an area with abundant limestone and clay reserves, strategic access to transportation facilities such as the Suramadu Bridge, Kamal Port, and Tanjung Perak Port, and proximity to suppliers of gypsum, fly ash, and copper slag. The dry process method is selected for production due to its cost efficiency, lower energy consumption, and reduced emissions compared to the wet process. The plant is designed to operate continuously for 330 days per year with 184 employees, adopting a line-and-staff organizational system under the structure of a Limited Liability Company (PT). Supporting facilities include utility supply units, water treatment, and waste management to ensure efficient and sustainable operations. From an economic perspective, the construction period is projected at three years, requiring a fixed capital investment of Rp 1.03 trillion and working capital of Rp 123 billion, resulting in a total capital investment of Rp 1.16 trillion. The annual raw material cost is estimated at Rp 381 billion, with utility costs of Rp 33 billion. Projected annual sales revenue reaches Rp 1.04 trillion, while total production costs amount to Rp 737 billion. The financial analysis shows a loan interest rate of 7.67%, a return on investment (ROI) of 20.39% before tax and 15.29% after tax, with a payback period of 3 years and 4 months. The internal rate of return (IRR) is 11.04%, and the break-even point (BEP) is calculated at 33.14%.
