Abstract

Salah satu industri yang menyumbang dampak lingkungan adalah pembangkit listrik tenaga gas uap. Semakin meningkatnya permintaan produksi listrik, maka tentu semakin tinggi pula dampak lingkungan yang dihasilkan akibat dari aktivitas proses produksinya. Selain itu, dengan besarnya dampak lingkungan yang muncul, analisis finansial terkait dampak lingkungan juga penting dilakukan agar perusahaan tersebut memahami besarnya nilai ekonomi dari dampak lingkungan jika dikonversikan ke dalam kurs mata uang. Berdasarkan permasalahan tersebut, dilakukanlah suatu penelitian dengan menggunakan metode Life Cycle Assessment (LCA) dan Life Cycle Cost (LCC). Adapun tujuan dari penelitian ini yaitu untuk menentukan dan mengkaji potensi dampak lingkungan serta menganalisis biaya kategori dampak lingkungan yang muncul dari serangkaian daur hidup produk listrik. Ruang lingkup penelitian ini adalah cradle to grave dengan menggunakan metode EN 15804 + A2 dan Environmental Prices dalam analisisnya. Hasil analisis LCA menunjukkan bahwa lingkup gate memberikan kontribusi dampak lebih besar yaitu 198 kPt daripada lingkup cradle 120 kPt, dan lingkup grave 29,6 kPt. Dampak lingkungan terbesar pada lingkup gate adalah global warming potential. Hasil analisis LCC menunjukkan bahwa lingkup gate memberikan kontribusi biaya dampak lingkungan lebih besar yaitu Rp 932/kWh daripada lingkup cradle Rp 326,61/kWh, dan lingkup grave Rp 46,14/kWh. Biaya dampak lingkungan terbesar pada lingkup gate adalah land use.

One of the industries that contributes to environmental impacts is steam gas power plants. The increasing demand for electricity production, absolutely, increases the environmental impact of production process activities. At the same time, with the large environmental impacts that arise, financial analysis related to environmental impacts is also important so that the company understands the magnitude of the economic value of environmental impacts when converted into currency exchange rates. Based on these problems, research was carried out using the Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) methods. This research aims to determine and assess potential environmental impacts and analyze the costs of environmental impact categories that arise from a series of electrical product life cycles. The scope of this research is cradle-to-grave using the EN 15804 - A2 method and environmental prices in its analysis. The results of the LCA analysis show that the gate scope contributes a greater impact, namely 198 kPt, than the cradle scope of 120 kPt and the grave scope of 29.6 kPt. The biggest environmental impact on the gate scope is global warming potential. The results of the LCC analysis show that the gate scope contributes more to environmental impact costs, namely IDR 932/kWh, than the cradle scope, IDR 326.61/kWh, and the grave scope, IDR 46.14/kWh. The biggest environmental impact in the gate area is land use.
