%T EVALUASI EMISI KARBON BERDASARKAN AKTIVITAS AKADEMIK DAN OPERASIONAL MENGGUNAKAN PENDEKATAN LIFE CYCLE ASSESSMENT (LCA) DI FAKULTAS TEKNIK UNTIRTA
%O Hasil penelitian menunjukkan bahwa total emisi karbon yang dihasilkan dari aktivitas akademik dan operasional Fakultas Teknik Universitas Sultan Ageng Tirtayasa (UNTIRTA) berdasarkan metode Life Cycle Assessment (LCA) pada kategori Global Warming Potential 100 tahun (GWP100a) sebesar 2124,1 kg CO₂-eq. Sumber emisi terbesar berasal dari konsumsi listrik gedung Fakultas Teknik dengan kontribusi 1254,47 kg CO₂-eq atau sekitar 59% dari total emisi, diikuti oleh penggunaan sepeda motor sebesar 742,30 kg CO₂-eq dan kendaraan roda empat sebesar 122,90 kg CO₂-eq, sedangkan kontribusi bus kampus relatif tidak signifikan yaitu 4,46 kg CO₂-eq. Selain dampak pemanasan global, aktivitas operasional juga menghasilkan dampak lingkungan lain berupa penipisan lapisan ozon sebesar 2,25×10⁻⁵ kg CFC-11 eq, pengasaman sebesar 6,42 kg SO₂ eq, dan eutrofikasi sebesar 7,60 kg PO₄ eq. Berdasarkan hasil identifikasi sumber emisi utama dan analisis fishbone, strategi pengurangan emisi difokuskan pada sektor konsumsi listrik dan transportasi bermotor sebagai kontributor dominan emisi karbon di Fakultas Teknik UNTIRTA.
%X The results of this study indicate that the total carbon emissions generated from academic and operational activities at the Faculty of Engineering, Universitas Sultan Ageng Tirtayasa (UNTIRTA), based on the Life Cycle Assessment (LCA) method in the Global Warming Potential over a 100-year time horizon (GWP100a), amounted to 2,124.1 kg CO₂-eq. The largest emission source originated from building electricity consumption, contributing 1,254.47 kg CO₂-eq or approximately 59% of the total emissions, followed by motorcycle usage at 742.30 kg CO₂-eq and four-wheeled vehicles at 122.90 kg CO₂-eq, while emissions from campus buses were relatively insignificant at 4.46 kg CO₂-eq. In addition to global warming impacts, operational activities also resulted in other environmental impacts, including ozone layer depletion of 2.25×10⁻⁵ kg CFC-11 eq, acidification of 6.42 kg SO₂ eq, and eutrophication of 7.60 kg PO₄ eq. Based on the identification of major emission sources and fishbone analysis, emission reduction strategies are focused on electricity consumption and motorized transportation as the dominant contributors to carbon emissions at the Faculty of Engineering, UNTIRTA.
