PROSES KOMPOSTING LIMBAH PADAT RUMAH POTONG HEWAN DENGAN METODE AEROBIK DAN A2O ANAEROBIK-ANOKSIK-OKSIK

ABSTRAK

Rumah Potong Hewan RPH Pegirian menghasilkan 038 ton rumen 526 ton kotoran dan sisa pakan setiap hari. Limbah ini belum dimanfaatkan dan hanya dibuang ke TPA Benowo. Metode pengomposan aerobik dan A2O anaerobikanoksik- oksikaerobik dipilih sebagai alternatif pengolahan limbah padat ini. Penelitian ini bertujuan membandingkan proses pengomposan dengan metode aerobik dan A2O perubahan kadar N dan P selama pengomposan penyisihan emisi NH3 menggunakan kompos matang dan Granular Activated Carbon GAC serta penyisihan total coliform. Penelitian menggunakan isi rumen sebanyak 20 kg pada tiap reaktor. Penelitian dilakukan selama 50 hari dengan konfigurasi waktu 25-10-15 hari untuk A2O dan dolomit 2. Penelitian ini menggunakan suplai udara 0757 L.kg-1berat kering.min-1 dan 058 L.kg-1berat kering.min-1. Media filter dari GAC dan kompos digunakan untuk penyisihan emisi NH3. Penelitian ini menggunakan 20 reaktor uji dan 4 reaktor kontrol selama proses pengomposan. Degradasi karbon pada pengomposan aerobik lebih besar 9023-12188 dibanding A2O 6688-11272.Reduksi massa kompos dengan metode aerobik 5420-6215 sedangkan A2O 3460-4073. Pengomposan aerobik matang lebih cepat dibanding A2O dimana suhu telah stabil dari hari ke-48 pada kisaran 26-27oC serta rasio CN berkisar 644-1371 syarat SNI 19-7030-2004 berkisar 10-20. Suhu kompos akhir A2O masih bergerak turun pada 275-28oC. N-total selama pengomposan aerobik meningkat dari 308-324 menjadi 3571-654 kecuali reaktor kontrol. Sedangkan A2O N-total sebagian reaktor meningkat dari 311-332 menjadi 360-511 dan sebagian menurun dari 317-321 menjadi 252-305. P-total pada pengomposan aerobik meningkat dari 112-191 menjadi 281-379 sedang pada A2O menurun dari 129-221 menjadi 078- 186 kecuali reaktor B4. Penyisihan NH3 oleh filter GAC 12 kali lebih besar dibandingkan kompos matang. GAC mampu menyisihkan NH3 sebesar 7600 8423 sedangkan kompos matang sebesar 60006967. Penyisihan coliform pada proses aerobik berkisar 9383 9999 sedangkan A2O 5832-9998.


ABSTRACT

Pegirians slaughterhouse SH generates 038 tons of paunch manure 526 tons of manure and grass feed residues every day. This solid waste is not used and generally disposed of to Benowo landfill. Aerobic and anaerobic-anoxicoxic aerobic A2O methods were selected as alternative methods for treating the SH solid waste. This research was aimed to compare the aerobic and A2O composting processes changes of N and P concentrations during process NH3 removal with compost and Granular Activated Carbon GAC filters and coliform removal. The composting process was done using 20 kg of paunch manure in each reactor during 50 days were conducted with 20-15-10 day intervals for A2O process and addition of 2 dolomite. Aerobic condition was maintained with air supply of 0757 L.kg-1dry weight.min-1 and 058 L.kg-1dry weight.min-1. Filters from compost and GAC was used to remove the emission of NH3. A total 20 reactors and 4 control reactors were used during composting period. Degradation of carbon in aerobic composting was higher 9023-12188 than that of A2O 6688-11272. Aerobic composting could reduce the compost material up to 5420-6215 and that of the A2O process was 3460-4073. Compost from aerobic reactors reached maturity within 48 days which was faster than in A2O reactors. The temperature of aerobic compost was stable at 26-27oC with CN ratio was 644-1371requirement from SNI 19-7030-2004 is 10-20. Temperature of A2O compost was changed at 275-28oC. The N-total increased from 308-324 to 3571-654 in aerobic reactors. The N-total on several reactors of A2O increased from 311-332 to 360-511 and others decreased from 317-321 to 252-305. The P-total increased from 112-191 to 281- 379 in aerobic reactors but decreased from 129-221 to 078-186 in A2O. NH3 removal by GAC 12 times higher than compost filter which was 7600 8423 by GAC and 60006967 by compost. Coliform removal efficiencies were 9383-9999 in aerobic reactors and 5832-9998 in A2O reactors.
