Abstract

Dalam era globalisasi saat ini, nilai impor barang non-migas di Indonesia mengalami peningkatan, salah satunya adalah soda ash. Pada tahun 2024, diketahui terdapat defisit dari
nilai ekspor dan impor soda ash yang berpotensi menjadi keuntungan jika Indonesia mampu memproduksi soda ash. Namun, produksi soda ash dalam negeri masih terbatas, sehingga
belum mampu memenuhi kebutuhan. Soda ash dapat diproduksi menggunakan bahan baku CO2, NaCl, dan NH3. Melimpahnya emisi CO2 yang dihasilkan oleh PT XYZ memiliki potensi untuk
dimanfaatkan sebagai bahan baku produksi soda ash (Na2CO3) melalui teknologi carbon dioxide utilization. Namunpendirian pabrik soda ash memiliki potensi dampak lingkungan yang serius, karena proses kalsinasi pada produksi soda ash menghasilkan CO2. Oleh karena itu, pada proyek akhir ini dilakukan analisis potensi dampak lingkungan yang disebabkan
selama daur hidup proses produksi soda ash dari pemanfaatan karbon dioksida dan menentukan solusi alternatif untuk mengurangi dampak lingkungan tersebut. Metode yang digunakan adalah CML-IA : Baseline dengan lingkup analisis gate-to-gate yang mencakup proses produksi soda ash dari bahan baku hingga terbentuk produk yang terdiri dari lima section dan utilitas. Adapun data yang digunakan dalam proyek akhir ini adalah data primer, yaitu kapasitas bahan baku yang digunakan dan diperoleh dari perusahaan, serta data sekunder yang diperoleh dari hasil simulasi menggunakan software Aspen Plus dan perhitungan. Dengan berdasar pada SNI ISO
14040 dan 14044 dan menggunakan metode CML-IA Baseline, diketahui bahwa potensi dampak mungkin terjadi selama proses produksi soda ash di antaranya adalah Global Warming
Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Photochemical
Oxidation, Human Toxicity Potential (HTP) dengan GWP yang memiliki potensi dampak paling besar dan kontribusi terbesar dari Carbonation Section diikuti dengan Unit Utilitas
Boiler. Oleh karena itu, dalam kajian LCA ini diberikan saran program seperti instalasi absorber-stripper menggunakan MDEA untuk recovery CO2 di Carbonation Section dalam rangka mengurangi potensi dampak GWP, dan pemasangan hybrid air filter berbasis AHPC di Calcination Section untuk mengurangi release particulate matter (PM) ke atmosfer.

In today's era of globalization, the value of non-oil and gas imports in Indonesia has increased, one of which is soda ash. In 2024, there was a deficit in the value of soda ash exports and imports, which could potentially be an advantage if Indonesia were able to produce soda ash. However, domestic production of soda ash is still limited, so it is not yet able to meet demand. Soda ash can be produced using raw materials such as CO2, NaCl, and NH3. The abundance of CO2 emissions generated by PT XYZ has the potential to be utilized as raw material for soda ash production (Na2CO3) through carbon dioxide utilization technology. However, the establishment of a soda ash plant has the potential for serious environmental impacts, as the calcination process in soda ash production generates CO2. Therefore, this final
project analyzes the potential environmental impacts caused during the lifecycle of the soda ash production process from carbon dioxide utilization and determines alternative solutions to reduce these environmental impacts. The method used is CML-IA: Baseline with a gate-to-gate analysis scope covering the soda ash production process from raw materials to the formation of the product, consisting of five sections and utilities. The data used in this study are primary
data, namely the capacity of raw materials used and obtained from the company, as well as secondary data obtained from simulation results using Aspen Plus software and calculations. Based on SNI ISO 14040 and 14044 and using the CML-IA Baseline method, it is known that potential impacts may occur during the soda ash production process, including Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Photochemical
Oxidation, and Human Toxicity Potential (HTP), with GWP having the greatest potential impact and the largest contribution from the Carbonation Section, followed by the Boiler Utility Unit. Therefore, in this LCA study, recommendations are provided for programs such as installing an absorber-stripper using MDEA for CO2 recovery in the Carbonation Section to reduce the potential impact of GWP, and installing a hybrid air filter based on AHPC in the
Calcination Section to reduce the release of particulate matter (PM) into the atmosphere.
