Abstract

PT. Berau Coal merupakan salah adalah dengan salah satunya yaitu PT Berau Coal
– Site Lati (LMO). Sistem penambangan pada PT. Berau Coal – Site Lati (LMO) menggunakan sistem tambang terbuka dengan menggunakan metode back filling. PT Berau Coal – Site Lati (LMO) melakukan kajian Life Cycle Assessment yang bertujuan untuk meningkatkan kinerja lingkungan dan mengidentifikasi potensi dampak lingkungan akibat kegiatan produksi batubara. Metode penelitian ini mengacu pada SNI ISO 14040:2016 dan SNI ISO 14044:2017, Life Cycle Inventory, Life Cycle Impact Assesment dan Interpretasi. Perhitungan penilaian dampak dilakukan pada proses produksi dengan menggunakan metode kajian dampak CML IA Baseline dengan bantuan software Microsoft Excel. Dampak Lingkungan yang dikaji dalam penelitian ini yaitu meliputi potensi pemanasan global, potensi penipisan ozon dan potensi hujan asam dengan ruang lingkup kajian adalah cradle to gate. Ruang lingkup kajian meliputi proses produksi yang ada yaitu land clearing, top soil removal, drilling and blasting, material removal, coal getting, coal hauling dan coal crushing serta utilitas yang meliputi reklamasi, WWTP, utility mining dan workshop. Proses material removal memberikan kontribusi dampak tertinggi dengan menghasilkan potensi pemanasan global sebesar 30,2 kgCO2eq/ton batubara, potensi penipisan ozon sebesar 6,84 x 10-6 kgCFC-11eq/ton batubara dan potensi hujan asam sebesar 1,24 x 10-1 kg SO2eq/ton batubara. Potensi dampak lingkungan yang dihasilkan pada proses material removal disebabkan oleh penggunaan bahan bakar solar sebesar 89.284.166 L dengan menghasilkan emisi CO2 sebesar 238.174,44 tonCO2eq.

PT. Berau Coal is a coal mining located in East Kalimantan and operates three mining areas, one of which is PT Berau Coal – Site Lati (LMO). Mining system at PT. Berau Coal – Site Lati (LMO) is carried out using an open pit mining system using the back filling method. PT Berau Coal – Site Lati (LMO) conducted a Life Cycle Assessment which aims to improve environmental performance and identify potential environmental impacts due to coal production activities. This research method refers to SNI ISO 14040:2016 and SNI ISO 14044:2017, Life Cycle Inventory, Life Cycle Impact Assessment and Interpretation. The impact assessment calculation is carried out on the production process using the CML IA Baseline impact assessment method with the help of Microsoft Excel software. The environmental impacts studied in this study include global warning potential, ozone depletion potential and acid rain potential with the scope of the study being cradle to gate. The scope of the study covers the existing production processes, namely land clearing, top soil removal, drilling and blasting, material removal, coal getting, coal hauling and coal crushing and then utility processes namely reclamation, WWTP, utility mining and workshop The material removal process contributes the highest impact by producing a global warming potential of 30,2 kgCO2eq/tonne of coal, ozone depletion potential of 6,84 x 10-6 kgCFC-11eq/ton of coal. The potential environmental impact generated in the material removal process is caused by the use of diesel fuel of 89.284.166 L with CO2 emissions of 238.174,44 tonsCO2eq.
Keywords: Coal, Life Cycle Assessment, Goal and Scope, Life Cycle Inventory, Life Cycle Impact Assesment, Interpretation.
