Abstract

Dalam kegiatan proses produksi energi listrik PLTU, beberapa unit proses akan menghasilkan emisi yang berpotensi menimbulkan dampak pada lingkungan dan kesehatan manusia. Tujuan dari penelitian ini yaitu menganalisis dampak lingkungan yang paling dominan dan unit operasi yang memberikan kontribusi dampak lingkungan paling besar sehingga dapat menjadi inputan untuk mengevaluasi program yang telah diimplementasikan di perusahaan untuk mengurangi dampak lingkungan, serta memberikan rekomendasi prioritas program unggulan dalam menanggulangi dampak lingkungan secara tepat sasaran.
Analisis dampak lingkungan dilakukan dengan metode LCA menggunakan aplikasi SimaPro dengan metode CML-1A dan ReCiPe. Hasil analisis LCA menjadi dasar evaluasi penentuan program-program perusahaan terkait efisiensi energi dan pengurangan pencemaran udara. Program-program tersebut selanjutnya dianalisis menggunakan metode AHP dengan mempertimbangkan 3 aspek terdiri dari aspek finansial, aspek teknis, dan aspek lingkungan. Inputan data untuk pelaksanaan metode AHP berdasarkan dari responden expert internal perusahaan. Metode AHP menggunakan aplikasi expert choice (EC), hingga mendapatkan prioritas program unggulan yang mampu menurunkan dampak lingkungan.
Hasil analisis LCA menunjukkan bahwa proses produksi 1 kWh listrik memberikan kontribusi dampak lingkungan yang paling dominan berdasarkan metode CML-IA Baseline yaitu abiotic depletion fossil fuel sebesar 11,62466 MJ dan berdasarkan metode ReCiPe 2016 Midpoint yaitu dampak global warming sebesar 1.049575 kg CO2 eq dan dampak terrestrial acidification sebesar 0,003672 kg SO2 eq. Rekomendasi prioritas program unggulan pengelolaan lingkungan terkait dengan efisiensi energi yaitu pengaturan coal to air ratio, cleaning tube boiler, penggantian elemen air preheater, sedangkan prioritas program unggulan untuk pengurangan pencemaran udara adalah pengaturan coal to air ratio, tiny oil burner, perubahan pola operasi LFO pump. Dari analisis LCA diketahui bahwa dengan implementasi program pengaturan coal to air ratio terjadi pengurangan dampak global warming sebesar 71,01% (0,755846 kg CO2 eq) dan pengurangan dampak acidification sebesar 65,52% (0,002406 kg SO2 eq). Serta dengan implementasi program perubahan pola operasi LFO pump terjadi pengurangan dampak global warming sebesar 72,02 % (0,755891 kg CO2 eq) dan pengurangan dampak acidification sebesar 65,53% (0,002406 kg SO2 eq).

In the process of producing electricity, several process units will produce emissions that may have an impact on the environment and human health. The purpose of this study is to analyze the most dominant environmental impact and the operating unit that contributes the most to the environmental impact so that it can be used as input for evaluating programs that have been implemented in the company to reduce environmental impacts, as well as providing recommendations for priority leading programs in tackling environmental impacts appropriately.
Environmental impact analysis was carried out using the LCA method using the SimaPro application with the CML-1A and ReCiPe methods. The results of the LCA analysis become the basis for evaluating the determination of company programs related to energy efficiency and air pollution reduction. These programs are then analyzed using the AHP method by considering 3 aspects consisting of financial aspects, technical aspects, and environmental aspects. The data input for the implementation of the AHP method is based on the company's internal expert respondents. The AHP method uses an expert choice (EC) application, to get the priority leading programs that are able to reduce environmental impacts.
The results of the LCA analysis show that the production process of 1 kWh electricity contributes the most dominant environmental impact based on the CML-IA Baseline method is abiotic depletion fossil fuel of 11,62466 MJ and based on the 2016 Midpoint ReCiPe method are global warming of 1.049575 kg CO2 eq and terrestrial acidification of 0.003672 kg SO2 eq. The recommendations for environmental management priority leading programs related to energy efficiency are setting the coal to air ratio, cleaning tube boilers, replacing the air preheater element, while the priority leading programs for reducing air pollution are setting the coal to air ratio, tiny oil burner, changing the operating pattern of the LFO pump. It was concluded that the implementation of setting the coal to air ratio program effect on reduction in the impact of global warming by 71,01% (0,755846 kg CO2 eq) and reduction in the impact of acidification by 65,52% (0,002406 kg SO2 eq). As well as the implementation of LFO pump operational pattern change program effect on reduction in the impact of global warming by 72.02% (0.755891 kg CO2 eq) and reduction in the impact of acidification by 65.53% (0.002406 kg SO2 eq).
