AbstractDecomposition produces methane gas that contribute to greenhouse gas emissions. A research has been conducted to anticipate the occurrence of greenhouse gas emissions by composting of oil palm empty fruit bunches (EFB) waste with aerobic systems using lignocellulolytic bacterial decom-posers (LCBD) in a commercial scale. Two of the activities carried out areoptimization of anaerobic decomposition (pre-treatment) process and optimization of anaerobic-aerobic decompositionin a scale of 50 tons and 780 tons. The results showed that the best pre-treatment is decomposition using fungal decomposer (Acticomp) in an open area and covered with a plastic. In the anaerobic-aerobic decomposition system on scale of 50 tons, the best treatment is using fungal decomposer (Acticomp) and lcbd both for four weeks each while on a scale of 780 tons showed that EFB decomposition on combination of anaerobic and aerobic decom-position system within two months and two weeks respectively produce compost with the C/N ratio of 20.5. The properties of compost was perfectly mature and producing the highest number of green bean germinated seeds.AbstrakPengomposan atau dekomposisi secara anaerob menghasilkan gas metan yang dapat me-nyumbang emisi gas rumah kaca.Untuk antisipasi terjadinya emisi gas rumah kaca telah dilakukan penelitian pengomposan limbah tandan kosong kelapa sawit (TKKS) dengan sistem aerobik menggunakan dekomposer bakteri lignoselulolitik (DBLS)pada skala komersial. Dua kegiatan yang dilakukan adalah optimasi pengomposan anaerob (pre treatment) dan optimasi pengomposan anaerobik-aerobik masing-masing pada skala 50 ton dan 780 ton. Pada optimasi pengomposan dua faktor yang diuji adalah penggunaan dekomposer dan penutupan kompos sedangkan pada optimasi pengomposan anaerobik-aerobik diuji pengaruh penggunaan DBLS dan pengaruh penggunaan DBLS dan lama periode sistem pengomposan. Hasil pengujian menunjukkan bahwa pre treatment terbaik adalah pengomposan dengan dekomposer jamur (Acticomp) di areal terbuka dan ditutup terpal. Perlakuan pada sistem anaerobik-aerobik skala 50 ton terbaik adalah pengomposan dengan dekomposer jamur (Acticomp) selama empat minggu dan dengan DBLS selama empat minggu sedangkan pada skala 780 ton menunjukkan bahwa pengomposan TKKS pada kombinasi antara pe-ngomposan dengan dekomposer jamur (Acticomp) dan DBLS masing-masing dalam waktu dua bulan dan dua minggu menghasilkan kompos TKKS dengan rasio C/N 20,5 dengan karakter matang sempurna dan mampu menghasilkan jumlah biji kacang hijau berkecambah tertinggi.

ABSTRAK Drainase yang berlebihan dan penggunaan pupuk yang intensif diduga menjadi penyebab tingginya emisi gas rumah kaca (GRK) pada perkebunan kelapa sawit di lahan gambut. Penelitian ini bertujuan untuk mempelajari pengaruh tinggi muka air (TMA) saluran drainase, pupuk, serta amelioran terhadap emisi CO 2 dari perkebunan kelapa sawit di lahan gambut. Penelitian dilakukan dari bulan Januari 2010 sampai dengan Desember 2011, pada perkebunan sawit di lahan gambut, di Kecamatan Siak Kecil, Kabupaten Bengkalis, Riau, menggunakan rancangan petak terpisah, tiga ulangan. Petak utama adalah TMA saluran drainase (40, 60, dan 80 cm). Anak petak adalah pupuk dan amelioran: (1) dolomit 3 kg/pohon/tahun; (2) Pugam 10 kg/pohon/tahun; (3) Pupuk dosis rekomendasi (2,5 kg urea+2,75 kg SP-36+2,25 kg KCl+dolomit 2 kg)/pohon/tahun; (4) Pupuk 75% dosis rekomendasi pukan 20 kg/pohon/tahun; (5) Pupuk 75% dosis rekomendasi Pugam 2,5 kg/pohon. Parameter yang diamati adalah fluks CO 2 . Hasil penelitian menunjukkan bahwa pada TMA drainase 80 cm, perlakuan dolomit menghasilkan fluks CO 2 nyata paling tinggi (142,1 t/ha/tahun) dan terendah (44,5 t/ha/tahun) dicapai perlakuan pugam. Fluks CO 2 yang tinggi (130,6 t/ha/tahun) juga dicapai perlakuan pupuk dosis rekomendasi, khususnya pada TMA 40 cm. Pada musim kemarau TMA drainase berpengaruh nyata terhadap fluks CO 2 , terendah dicapai TMA 40 cm. Oleh karena itu, untuk meminimalkan emisi gas CO 2 , maka TMA drainase perlu dipertahankan sedangkal mungkin (sekitar 40 cm) selama tidak menurunkan produksi kelapa sawit. Amelioran dengan bahan aktif kation polyvalen berpotensi dapat menekan emisi GRK dari lahan gambut yang dikelola secara intensif. Kata kunci: amelioran, emisi, drainase, gambut, kelapa sawit, pupukABSTRACT Excessive drainage and intensive use of fertilizers thought to be the cause of high greenhouse gas emissions in peatland under oil palm plantations. The study aimed at measuring the influence of water level drainage (WLD), fertilizer, and ameliorant on CO 2 emissions from oil palm plantations on peatland. The study was conducted from January 2010 to December 2011, at oil palm plantation on peatland, located in Siak Kecil District, Bengkalis Regency, Riau, using split plot design, with three replications. The main plot were WLD (40, 60, and 80 cm), as sub plots were fertilizer and amelioran: (1) dolomite 3 kg/tree/year; (2) peat fertilizer 10 kg/tree/year; (3) dose of fertilizer recommendations (2,5 kg urea+2,75 kg SP-36+2,25 kg KCl+dolomite 2 kg)/tree/year; (4) 75% dose of fertilizer recommendations + manure 20 kg/tree/year; (5) 75% dose of fertilizer recommendations + peat fertilizer 2.5 kg/tree/year. Parameter observed was CO 2 flux. The result showed that at WLD 80 cm, dolomite treatment resulted the highest (142,1 t/ha/year) and the lowest CO 2 flux (44,5 t/ha/year) resulted by peat fertilizer. The highest CO 2 flux also reached by fertilizer recommendations treatment, particularly on WLD 40 cm. In dry season WLD significantly effect on CO 2 flux. The lowest reached by WLD 40 cm. Based on that the WLD needs to be maintained in a state of shallow (approximately 40 cm), without lowering production. The use of fertilizer containing ameliorant with the polyvalen cation as active material, potentially suppress the rate of greenhouse gas emissions from peatlands are managed intensively. Key words: ameliorant, emission, drainage, peatland, oil palm, , fertilizer

This study investigated emissions of CH4, N2O and NH3 from nine anaerobic digestion plants that treat biowaste. The treatment is in form of mechanical pre-treatment, anaerobic digestion followed by a composting with or without intensive aeration. The exhaust gases from the mechanical and anaerobic steps are treated by biofilters. The emission sources at the plants consisted of biofilters, combined heat and power units (CHP), liquid digestate treatment systems (LTS) and open composting windrows of the solid digestate. Overall, the emission factors were 0.4 - 16 kg (Mg biowaste)-1 for CH4, 7 - 170 g (Mg biowaste)-1 for N2O and 41 - 6,032 g (Mg biowaste)-1 for NH3. Open composting windrows of solid digestate resulted in high emissions of CH4 and N2O. Intensive aeration of the solid digestate could reduce greenhouse gas emissions.
