Abstract

Pencemaran udara menjadi isu lingkungan yang semakin mendesak, khususnya di kawasan industri petrokimia. Salah satu sumber utama emisi adalah pelepasan gas buang hidrokarbon melalui flare stack. PT XYZ, sebagai salah satu industri petrokimia terbesar di Timur Tengah, menghadapi tantangan signifikan dalam mengurangi emisi gas berbahaya seperti metana, etana, dan etilena. Penelitian ini bertujuan untuk mengkaji penerapan teknologi Flare Recovery Unit (FRU) dalam mendukung pengelolaan limbah gas secara lebih efisien dan ramah lingkungan melalui pendekatan Green Manufacturing, yang sejalan dengan prinsip zero waste dan net zero emission. Metode penelitian yang digunakan adalah pendekatan mix method dengan studi kasus yang dilakukan dalam dua tahap, yaitu di mulai kuantitatif dan dilanjutkan dengan pendekatan kualitatif untuk menjelaskan atau memperdalam hasil kuantitatif. Data primer diperoleh melalui Kuesioner, Observasi teknis di lokasi penelitian dan Forum Group Discussion (FGD), sementara data sekunder dikumpulkan dari dokumen internal perusahaan dan literatur ilmiah yang relevan. Hasil penelitian menunjukkan bahwa FRU berhasil menangkap dan mengolah gas buang, yang kemudian dimanfaatkan kembali dalam proses produksi. Penerapan prinsip reduce, reuse dan recycle terbukti meningkatkan efisiensi energi dan mengurangi pencemaran udara. Analisis dengan Pengurangan Emisi CO₂ Analysis, Material Flow Analysis (MFA) dan Energy Flow Analysis (EFA) mendukung temuan ini. Dari aspek ekonomi, sistem FRU sangat layak diterapkan. Hal ini dibuktikan melalui nilai Net Present Value (NPV) yang tinggi, Internal Rate of Return (IRR) di atas ambang kelayakan, Payback Period (PBP) yang relatif singkat serta Benefit-Cost Ratio (BCR) yang sangat layak. Temuan ini menegaskan bahwa inovasi seperti FRU dapat menjadi bagian integral dari strategi bisnis berkelanjutan, sekaligus mendukung target lingkungan nasional melalui pengurangan emisi dan peningkatan efisiensi sumber daya.

Air pollution has become an increasingly urgent environmental issue, particularly in petrochemical industrial zones. One of the main sources of emissions is the release of hydrocarbon waste gases through flare stacks. PT XYZ, as one of the largest petrochemical industries in the Middle East, faces significant challenges in reducing harmful gas emissions such as methane, ethane, and ethylene. This study aims to examine the application of Flare Recovery Unit (FRU) technology to support more efficient and environmentally friendly gas waste management through a Green Manufacturing approach, in line with the principles of zero waste and net zero emission. The research method employed is a mixed-method approach using a case study design, Sequential Mixed Method, which is conducted in two stages: beginning with a quantitative approach, followed by a qualitative approach to explain or deepen the quantitative findings. Primary data were collected through Quetioner, technical observations at the research site and Forum Group Discussion (FGD) while secondary data were obtained from internal company documents and relevant scientific literature. The results show that FRU successfully captures and processes waste gases, which are then reused in the production process. The application of the reduce, reuse and recycle principles has proven to improve energy efficiency and reduce air pollution. These findings are supported by Reduction Emission of CO₂ Analysis, Material Flow Analysis (MFA) and Energy Flow Analysis (EFA). From an economic perspective, the FRU system is highly feasible. This is evidenced by a high Net Present Value (NPV), an Internal Rate of Return (IRR) above the viability threshold, a relatively short Payback Period (PBP) also very feasible of Benefit-Cost Ratio (BCR). These results confirm that innovations such as FRU can become an integral part of sustainable business strategies, while also supporting national environmental targets through emission reduction and improved resource efficiency.
