Abstract
Sektor industri Indonesia menjadi kontributor utama emisi gas rumah kaca nasional—mencapai 88% pada 2022 dengan tren intensitas emisi yang terus meningkat sebesar 4,3% dalam empat tahun terakhir.. Untuk mengurangi dampak lingkungan, pemanfaatan CO₂ sebagai bahan baku produksi kalium karbonat (K₂CO₃) menjadi solusi inovatif. Saat ini, kebutuhan K₂CO₃ di Indonesia masih bergantung pada impor sebesar 10.554.307 kg/tahun (2022), dengan pertumbuhan rata-rata 0,48% per tahun. Berdasarkan proyeksi kebutuhan tahun 2029 sebesar 10.253 ton/tahun, pabrik K₂CO₃ dirancang dengan kapasitas 3.121 ton/tahun, setara dengan 30% kebutuhan nasional. Pabrik ini akan memanfaatkan 1.084 ton CO₂/tahun dari PT Petrokimia Gresik dan beroperasi selama 330 hari/tahun secara kontinu. Pemilihan lokasi menggunakan metode AHP dengan mempertimbangkan faktor bahan baku, utilitas, tenaga kerja, dan aksesibilitas. Pabrik direncanakan mulai beroperasi pada tahun 2029 dan bertempat pada Kecamatan Gresik, Kabupaten Gresik, Jawa Timur. Rancangan pembangunan pabrik ini akan mencakup diagram alur proses (PFD), diagram instrumentasi dan perpipaan (P&ID) sederhana, studi bahaya dan operabilitas (HAZOP) awal, spesifikasi peralatan, dan analisis ekonomi. Dengan periode konstruksi selama 4 tahun dan masa ekonomis pabrik yang diperkirakan selama 15 tahun, studi kelayakan menunjukkan bahwa pabrik ini layak untuk didirikan, dengan proyeksi tingkat pengembalian internal (IRR) sebesar 21,05%. Pay Out Time adalah 4 tahun, dengan Break Even Point sebesar 15% sehingga Pabrik Kalium Karbonat layak didirkan.

Since 2022, the industrial sector in Indonesia has been the dominant contributor to national greenhouse gas (GHG) emissions, accounting for 88% in 2022, with emission intensity trends increasing by 4.3% over the past four year. In order to reduce the environmental problem, utilization of CO₂ as the raw material for producing potassium carbonate (K₂CO₃) is one of the inovative solution. The current demand of K₂CO₃ in Indonesia still depends on the supply from imports of 10.554.307 kg/year (2022), with the increase of 0,48% per year. According to the pojection of market demand calculated for 2029 is 10.253 ton/year, K₂CO₃ plant is designed with the capacity of 3.121 ton/year, equal to 30% national demand. This plant utilizes 1.084 ton CO₂/year as the byproduct of PT Petrokimia Gresik and will be operating continously for 330 days/year. Location selecting process using AHP method with several factors such as raw material, utility, labor, dan accessibility. Pabrik is planned to start operating in 2029 and located at Kecamatan Gresik, Kabupaten Gresik, East Java. The plant design will include a Process Flow Diagram (PFD), a simplified Piping and Instrumentation Diagram (P&ID), an initial Hazard and Operability (HAZOP) study, equipment specifications, and an economic analysis. The estimated construction period is 4 years, with an expected economic lifetime of 15 years. Feasibility analysis indicates that the plant is financially viable, with a projected Internal Rate of Return (IRR) of 21,05%, a Pay Out Time (POT) of 4 years, and a Break Even Point (BEP) of 15%, making the K₂CO₃ plant highly feasible to be established.
