Abstract

Indonesia merupakan salah satu negara penyumbang emisi global dengan total 1,981 miliar ton emisi karbon dioksida (CO2) per tahunnya. Pendorong utama peningkatan emisi ini dihasilkan dari berkembangnya sektor industri. Aktivitas sektor industri menyumbang 39 juta ton emisi berupa gas rumah kaca (CO₂, CH4, dan N2O) dan polutan udara yang terlepas ke atmosfer yang dapat berdampak pada lingkungan, termasuk pemanasan global, hujan asam, dan gangguan kesehatan. Sebagai salah satu perusahaan petrokimia terbesar di Asia Tenggara, PT Trans-Pacific Petrochemical Indotama (TPPI) Tuban pada proses produksinya seperti pembakaran bahan bakar, flaring, dan kebocoran peralatan turut menyumbang emisi yang signifikan ke lingkungan. Untuk mengurangi dampak emisi terhadap lingkungan, perlu dilakukan analisis pada proses produksi sebagai strategi penting dalam menganalisis emisi, konsumsi energi, dan bahan baku sepanjang siklus hidup produksi. Penelitian ini bertujuan untuk menghitung emisi dan mengevaluasi dampak emisi terhadap lingkungan yang timbul dari proses produksi di PT TPPI melalui pendekatan gate to gate, yaitu pada unit produksi di Platforming dan Aromatic Plant. Metode yang digunakan pada analisis Life Cycle Assessment (LCA) yaitu dengan metode pendekatan midpoint CML-1A Baseline. Emisi yang dianalis yaitu CO2, SO2, NO2, N2O, CH4 dan PM. Tahap penelitian dimulai dari penentuan goal dan scope. Hasil analisis emisi, bahan bakar, dan energi dianalisis pada tahapan Life Cycle Inventory (LCI). Selanjutnya, dilakukan identifikasi dampak menggunakan metode Life Cycle Impact Assessment (LCIA) dengan menggunakan software Microsoft Excel yang selanjutnya dilakukan interpretasi data. Dampak lingkungan yang dianalisis yaitu Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Photochemical Oxidation, dan Human Toxicity Potential (HTP). Hasil dari penelitian ini yaitu didapatkan total emisi dari proses produksi pada Tahun 2023 yaitu sebesar 421.563,91 Ton CO2; 84.965,27 Ton CO2 sekunder (dari konsumsi listrik); 19,70 Ton CH4; 3,94 Ton N2O; 76,91 Ton SO2; 2.273,04 Ton NO2; dan 228,02 Ton PM. Dampak emisi terhadap lingkungan yang dihasilkan diantaranya yaitu Global Warming Potential (GWP) sebesar 233,452 kg CO₂-eq/Ton Produk; Acidification Potential (AP) sebesar 0,633 kg SO₂ eq/Ton Produk; Eutrophication Potential (EP) sebesar 0,153 kg PO₄-eq/Ton Produk; Photochemical Oxidation sebesar 0,035 kg C₂H₄-eq/Ton Produk, dan Human Toxicity Potential (HTP) sebesar 1,536 kh 1,4-DCB eq/Ton Produk. Adapun titik hotspot yaitu pada Unit 203 Platforming dan Unit 211 Aromatic Fractination. Rekomendasi alternatif perbaikan diantaranya yaitu penerapan Carbon Capture and Storage dan Carbon Capture and Utilisation Storage (CCS/CCUS); adsorpsi CO2 menggunakan adsorban zeolit; dan penambahan Air Preheater (APH) pada Heater.

Indonesia is one of the global emission contributors with a total of 1.981 billion tons carbon dioxide (CO2) emissions per year. The main driver of this emission increase comes from the growing industrial sector. Industrial sector activities contribute 39 million tons of emissions in the form of greenhouse gases (CO₂, CH4, dan N2O) and air pollutants released into the atmosphere that can impact the environment, including global warming, acid rain, and health problems. As one of the largest petrochemical companies in Southeast Asia, PT Trans-Pacific Petrochemical Indotama (TPPI) Tuban in its production processes such as fuel combustion, flaring, and equipment leakage contributes significant emissions to the environment. To reduce emission impacts for the environment, analysis of the production process needs to be conducted as an important strategy in analyzing emissions, energy consumption, and raw materials throughout the production life cycle. This study aims to calculate emission loads and evaluate emission impacts for environmental arising from production processes at PT TPPI through a gate-to-gate approach, specifically in the production units at Platforming and Aromatic Plant. The method used in Life Cycle Assessment (LCA) analysis is the CML-1A Baseline midpoint approach. The emissions analyzed are CO2, SO2, NO2, N2O, CH4 and PM. The research phase begins with determining goals and scope. The analysis results of emission loads, fuel, energy, and raw materials are analyzed in the Life Cycle Inventory (LCI) stage. Subsequently, impact identification is conducted using the Life Cycle Impact Assessment (LCIA) method using Microsoft Excel software, followed by data interpretation. The environmental impacts analyzed are Global Warming Potential (GWP), Acidification Potential (AP), Eutrophication Potential (EP), Photochemical Oxidation, and Human Toxicity Potential (HTP). The results of this study show that the total emission load from the production process in 2023 includes 421,563.91 tons of CO₂; 84.965,27 tons of secondary CO₂ (from electricity consumption); 19.70 tons of CH₄; 3.94 tons of N₂O; 76.91 tons of SO₂; 2,273.04 tons of NO₂; and 228.02 tons of PM. The corresponding environmental impacts are as follows: Global Warming Potential (GWP) of 233.452 kg CO₂-eq/ton of product; Acidification Potential (AP) of 0.633 kg SO₂-eq/ton of product; Eutrophication Potential (EP) of 0.153 kg PO₄-eq/ton of product; Photochemical Oxidation of 0.035 kg C₂H₄-eq/ton of product; and Human Toxicity Potential (HTP) of 1.536 kg 1,4-DCB-eq/ton of product. Identified hotspots are in Unit 203 (Platforming) and Unit 211 (Aromatic Fractionation). Recommended improvement alternatives include the implementation of Carbon Capture and Storage (CCS) and Carbon Capture, Utilization, and Storage (CCUS); CO₂ adsorption using zeolite adsorbents; and the addition of an Air Preheater (APH) in the heater system.
