Abstract
Indonesia telah berkomitmen untuk mengurangi emisi karbon sebagai langkah penanggulangan pemanasan global. Salah satu penerapannya adalah dengan menciptakan green industry dimana dapat meminimalisir bahkan memanfaatkan emisi karbon sebagai bahan dasar pembuatan produk. Industri terbesar kedua penghasil emisi karbon adalah power plant, sehingga pada desain pabrik ini digunakan sebagai penyuplai bahan baku utama dalam bentuk flue gas. Flue gas yang digunakan bersumber dari PT. PJB Paiton dengan flowrate 236.832 ton/jam mengandung 16% CO2. Pemanfaatan CO2 dari flue gas yang direaksikan dengan larutan NaOH akan menghasilkan produk NaHCO3 solid untuk memenuhi kebutuhan dalam negeri yang masih menggunakan 100% produk impor. Flue gas akan melewati proses desulfurisasi sebelum akhirnya direaksikan dengan larutan NaOH 15% dalam proses karbonasi untuk menghasilkan NaHCO3 (Natrium bikarbonat) yang kemudian difiltrasi, dikeringkan, dan penyesuaian ukuran. Produk NaHCO3 yang dihasilkan memiliki kemurnian 99,1%. Kapasitas produksi pabrik sebesar 500.000 ton/tahun dengan pabrik beroperasi secara kontinyu selama 330 hari/tahun dengan mempertimbangkan aspek ekonomi berupa Internal Rate of Return (IRR) sebesar 26,55%, Pay Out Time (POT) selama 5,57 tahun dan Break Even Point (BEP) sebesar 49,25%. Pendirian pabrik dalam segi sosial, ekonomi, dan lingkungan bertujuan untuk membuka lapangan pekerjaan baru, pengurangan ketergantungan produk impor, serta meminimalisir emisi karbon. Berdasarkan penilaian dari aspek ekonomi dan teknisnya, maka pabrik natrium bikarbonat dari CO2 dan NaOH layak untuk didirikan.

Indonesia has committed to reducing carbon emissions as a measure to address global warming. One of the implementations is the creation of a green industry that can minimize or even utilize carbon emissions as raw materials for product manufacturing. The second-largest carbon-emitting industry is power plants, wherein this plant's design utilizes flue gas as the main raw material supplier. The flue gas used is sourced from PT. PJB Paiton, with a flow rate of 236.832 tons/hour and containing 16% CO2. The CO2 from the flue gas, when reacted with NaOH solution, will produce NaHCO3 solid (Sodium bicarbonate) products to meet domestic demand, which currently relies entirely on imported products. The flue gas will undergo a desulfurization process before being reacted with 15% NaOH solution in the carbonation reaction to produce NaHCO3. The resulting sodium bicarbonate will then be filtered, dried, and sized accordingly. The produced NaHCO3 product has a purity of 99.1%. The factory's production capacity is 500,000 tons per year, operating continuously for 330 days per year, considering economic aspects such as an Internal Rate of Return (IRR) of 26.55%, Pay Out Time (POT) of 5.57 years, and Break Even Point (BEP) of 49.25%. The establishment of this plant aims to have social, economic, and environmental benefits, including creating new job opportunities, reducing dependence on imported products, and minimizing carbon emissions. Based on its economic and technical aspects, the sodium bicarbonate plant using CO2 and NaOH is deemed feasible for establishment.
