Abstract

Precipitated Calcium Carbonate (PCC) merupakan bahan aditif penting dalam industri kertas, plastik, cat, dan karet karena kemurnian, ukuran partikel yang terkontrol, serta sifat optiknya yang unggul. Seiring meningkatnya kebutuhan PCC, khususnya pada industri kertas di Indonesia, diperlukan perancangan pabrik PCC yang efisien, berkelanjutan, dan kompetitif secara ekonomi. Perancangan pabrik dilakukan dengan mengevaluasi beberapa metode produksi PCC, yaitu metode karbonasi, lime soda, Solvay, dan SkyCycle. Pemilihan proses dilakukan menggunakan pendekatan Analytical Hierarchy Process (AHP). Berdasarkan hasil evaluasi, metode SkyCycle dipilih sebagai metode yang paling optimal. Bahan baku utama berupa steel slag dan gas buang blast furnace dimanfaatkan sebagai sumber kalsium dan karbon dioksida, sehingga mendukung konsep pemanfaatan limbah industri dan pengurangan emisi karbon. Pabrik dirancang berlokasi di Kawasan Industri Krakatau, Cilegon, Banten, dengan mempertimbangkan kedekatan terhadap sumber bahan baku, infrastruktur, serta pasar utama industri kertas. Proses produksi meliputi tahap size reduction, alkali fusion, water leaching, acid leaching, reaksi presipitasi, pemisahan padat-cair, pengeringan, dan pengolahan ulang bahan pendukung. Sehingga, dihasilkan PCC sebanyak 821 kg/jam dengan tingkat kemurnian (purity) 98,07% dan kandungan air 0,028%. Selain itu, dilakukan analisis awal kelayakan ekonomi untuk menilai potensi keberlanjutan pabrik. Pembangunan pabrik PCC dengan kapasitas 6.500 ton/tahun diperkirakan akan mencapai NPV Rp365,733,260,779.3, IRR 24.51%, POT 6.3 tahun, dan BEP tercapai pada kapasitas 43%. Hasil perancangan menunjukkan bahwa pabrik PCC yang dirancang memiliki potensi untuk memenuhi kebutuhan industri nasional dengan pemanfaatan sumber daya yang lebih efisien dan ramah lingkungan. Dengan demikian, perancangan ini diharapkan dapat menjadi alternatif pengembangan industri PCC berbasis konsep green industry di Indonesia.

Precipitated Calcium Carbonate (PCC) is a critical additive in the paper, plastics, paint, and rubber industries due to its high purity, controlled particle size, and superior optical properties. With the increasing demand for PCC, particularly in the Indonesian paper industry, the design of a PCC production plant that is efficient, sustainable, and economically competitive is required. In this study, the plant design was carried out by evaluating several PCC production methods, namely the carbonation, lime-soda, Solvay, and SkyCycle processes. The selection of the most appropriate process was conducted using the Analytical Hierarchy Process (AHP) approach. Based on the evaluation results, the SkyCycle method was identified as the most optimal process. The primary raw materials consist of steel slag and blast furnace exhaust gas, which are utilized as sources of calcium and carbon dioxide, respectively. This approach supports the concept of industrial waste valorization and carbon emission reduction. The plant is designed to be located in the Krakatau Industrial Area, Cilegon, Banten, the primary market of the paper industry. The production process comprises several stages, including size reduction, alkali fusion, water leaching, acid leaching, precipitation reaction, solid–liquid separation, drying, and the regeneration of auxiliary materials. As a result, the plant is designed to produce 821 kg/h of PCC with a product purity of 98.07% and a moisture content of 0.028%. Furthermore, a preliminary economic feasibility analysis was conducted to assess the sustainability and economic viability of the proposed plant. The results indicate that the PCC plant with a capacity of 6.500 ton/year is expected to achieve a NPV of IDR Rp365,733,260,779.3, an IRR of 24.51%, a POT of 6.3 years, and a BEP achieved at 43% of production capacity. Overall, the design results demonstrate that the proposed PCC plant has significant potential to meet national industrial demand through more efficient and environmentally friendly resource utilization. Therefore, this design is expected to serve as an alternative model for the development of a green industry–based PCC production in Indonesia.
