Perancangan Teknologi Pengelolaan Landfill Gas di TPA Galuga Berdasarkan Analisis LandGEM

Abstract

TPA Galuga menerima sekitar 800–900 ton sampah per hari dari Kota dan Kabupaten Bogor sehingga berpotensi menghasilkan landfill gas (LFG) yang didominasi metana (CH4). Penelitian ini bertujuan menganalisis produksi LFG menggunakan LandGEM, potensi pemanfaatannya sebagai energi, serta teknologi pengelolaan yang sesuai. Data diperoleh melalui wawancara, data timbulan sampah, literatur, dan dokumen operasional TPA. Estimasi menggunakan pendekatan first-order decay, sedangkan pemilihan teknologi menggunakan Cost Benefit Analysis. Hasil menunjukkan potensi energi termal 21,30 MW dan daya listrik 7,46 MW dengan efisiensi generator 35%. Sumur vertikal dan PLTSa menjadi alternatif teknologi paling sesuai untuk mengurangi emisi dan menghasilkan energi terbarukan secara berkelanjutan.

TPA Galuga receives approximately 800–900 tons of waste per day from Bogor City and Bogor Regency, generating landfill gas (LFG) predominantly composed of methane (CH4). This study aims to analyze LFG production using Landfill Gas Emissions Model (LandGEM), assess its potential utilization as an energy source, and determine appropriate LFG management technology. Data were obtained through interviews, waste generation data, literature, and landfill operational documents. LFG production was estimated using a first-order decay approach, while technology selection employed the Cost Benefit Analysis. The results indicate a thermal energy potential of 21.30 MW and an estimated electricity generation capacity of 7.46 MW at 35% generator efficiency. Vertical extraction wells and Waste-to-Energy (WtE) technology were identified as the most suitable alternatives for reducing greenhouse gas emissions and generating renewable energy.
