Prediksi Potensi Pencemaran Pengolahan Sampah dengan Metode Gasifikasi Fluidized Bed (Studi Kasus: TPA Benowo, Surabaya)

Abstract

Sistem pengelolaan sampah di TPA Benowo masih bersistem open dumping dan belum memperhatikan dampak pencemaran terhadap lingkungan. Kuantitas sampah yang masuk ke TPA sebesar 461.705,782 ton pada tahun 2012. Kuantitas sampah diperkirakan meningkat sebanding dengan pertumbuhan penduduk, sehingga dibutuhkan skenario pengolahan sampah yang ramah lingkungan. Skenario pengolahan sampah yang akan dikaji adalah gasifikasi fluidized bed. Potensi pencemaran gasifikasi fluidized bed akan dikaji menggunakan metode Life Cycle Assessment (LCA) dengan software SimaPro versi 7.1. Satu ton sampah pada studi ini ditentukan sebagai satu fungsi unit. Data input Life Cycle Inventory (LCI) meliputi jumlah sampah yang masuk ke reaktor gasifikasi dan energi yang dibutuhkan pada proses gasifikasi berdasarkan pendekatan efisiensi reaktor gasifikasi. Penentuan nilai Life Cycle Impact Assesment (LCIA) meliputi Global Warming Potential (GWP) dan asidifikasi menggunakan metode Environmental Product Declarations (EPD) 2008. Besar dampak dinyatakan dalam faktor emisi yang ekivalen. Kesimpulan pada penelitian ini menunjukkan bahwa skenario pengolahan sampah dengan metode gasifikasi fluidized bed memberikan dampak GWP sebesar 1067,8 kg CO2/fu pada fase start-up dan 875 kg CO2/fu pada fase energy recovery serta asidifikasi sebesar 5,93 kg SO2/fu pada fase start-up dan 4,81 kg SO2/fu pada fase energy recovery.
