Abstract

Gas and Steam Power Plant (PLTGU) PT. PLN (Persero) Belawan Generation Control Implementation Unit (UPDK) is the main supplier of electricity needs in the Northern Sumatra System. In the initial period of operation, PLTGU PT. PLN UPDK Belawan uses diesel oil as fuel. The use of fuel originating from the bowels of the earth certainly produces greenhouse gas (GHG) emissions. Since 2015, this PLTGU has started using natural gas as fuel. Changes in fuel use will affect the GHG emission load resulting from the Belawan PLTGU. This research aims to analyze the GHG emission load from the two types of fuel and examine the differences in GHG emissions when the conversion of diesel fuel to natural gas occurs. The emission load calculation uses the IPCC method and guidelines from the Ministry of Energy and Mineral Resources with national emission factors, meanwhile, to carry out real difference tests using the WSR test from SPSS. The results of the emission load calculation show that there is a difference in the greenhouse gas emission load produced before using natural gas fuel and when using natural gas fuel of 20.85%. This shows that fuel conversion from diesel oil to natural gas can reduce the burden of household gas emissions

Abstract

Coal-fired power plants will emit several types of pollutants into the ambient air such as particulates and gases. One way to estimate the extent of the impact distribution of these pollutants is by using air quality modeling. The model used in this study is Calpuff, where this model is a non-steady state model and is influenced by variations in meteorological factors. The research location is PLTU Pangkalan Susu (2x200 MW) with SO2 and NO2 parameters. The purpose of this study was to calculate the concentrations of SO2 and NO2 with Calpuff, to validate modeling with field observations and to simulate the distribution of impacts. The results showed that the concentration of SO2 model obtained was 0.32 - 3.57 µg/m3 and NO2 was 0.51 - 5.15 µg/m3. Meanwhile, the observation results showed that the SO2 concentration was 27 - 39.88 µg/m3 and NO2 was 19.77 - 29.73 µg/m3. The simulation results of the distribution of SO2 and NO2 concentrations with the Calpuff model show that the impact distribution area is in the direction of the wind in the windrose and the affected area is in the southwest of the PLTU Pangkalan Susu. The results of model validation for the values ​​of d = 0.97, r = 0.616 - 0.665 and FB = -1.719 - -1.849, which means that the Calpuff model is quite valid and can be applied to predict the impact distribution area at PLTU Pangkalan Susu.

Abstract

Pemanasan global menjadi permasalahan krusial yang berdampak terhadap lingkungan, terutama disebabkanolehemisi gas rumah kaca (GRK) dari sektor energi. PT PLN Indonesia Power Pangkalan Susu PGU, sebagai pembangkit listrik berbahan bakar batubara, bertanggung jawab mengurangi dampak lingkungan dari operasional PLTU. Penelitian ini bertujuan mengevaluasi potensi serapan karbon dari program penghijauan PT PLN Indonesia Power Pangkalan Susu PGU serta nilai ekonominya. Metode yang digunakan adalah persamaan allometrik untuk mengukur serapan karbon dan perhitungan nilai ekonomi dengan metode proxy good technique. Penelitian ini mengidentifikasi potensi serapan karbon dan nilai ekonomi dari program penghijauan di lokasi operasional (8,57 ha) dan lokasimangrove (2 ha) di Desa Pasar Rawa. Hasil penelitian menunjukkan total serapan karbon mencapai 1.231,06 tonCO2 per tahun dengan nilai ekonomi sebesar 12.310,68 USD dolar atau sekitar Rp201.895.152,00 per tahun, berdasarkanharga pasar karbon sebesar 10 dolar per ton CO2. Meskipun memberikan manfaat lingkungan dan nilai ekonomi, programini masih defisit dalam memenuhi persetujuan teknis batas atas emisi (PTBAE) yang ditetapkan oleh KementerianESDM. Untuk memenuhi target emisi pada tahun 2024, diperlukan pengurangan sebesar 353.744,58 ton CO2e yangmembutuhkan lebih luas lagi lahan penghijauan. Kata Kunci: emisi gas rumah kaca, nilai ekonomi karbon, pemanasan global, penghijauan, serapan karbon
