Emisi GRK dari Peternakan Enteric Fermentation (Fermentasi Enterik) Methan (CH4) Manure Management (Pengelolaan Kotoran) Direct N2O Indirect N2O CH4
Enteric Fermentation Ternak ruminansia (sapi potong, sapi perah, kerbau, domba, kambing), kuda, babi menghasilkan Methan (CH4). Gas yang dihasilkan ternak ruminansia adalah CO2, CH4, H2S, H2O Methan dihasilkan dari proses methanogenesis di dalam rumen dengan bantuan bakteri methanogen. CO2 + 4H2 ==> CH4 + 2H2O
CH4 Manure Management Methan: Dihasilkan dari proses penanganan manure (manure management) pada semua jenis ternak (sapi perah, sapi potong, kerbau, domba, kambing, babi, itik, ayam ras, ayam kampung, ayam petelur) secara anaerobik Penanganan secara liquid (kondisi anaerob) lebih memungkinkan terjadinya methanogenesis dibandingkan penanganan secara solid. CH4
Manure Management N2O N2O Direct N2O Indirect N2O Dihasilkan dari proses kombinasi nitrifikasi dan detrifikasi N dari manur selama dalam penyimpanan. Proses nitrifikasi adalah perubahan N-ammonia menjadi N-nitrat dalam kondisi oksigen yang cukup. Indirect N2O Dihasilkan dari N-volatile seperti NH3 atau NOx. N organic yang mudah menjadi volatil adalah urea dan ureic acid N2O N2O
Faktor Emisi pada ternak tergantung dari berbagai hal: Jenis dan Bangsa Ternak Berat Badan, Umur Produksi Susu/Kerja Status reproduksi Kualitas Pakan Sistem Pemberian Pakan Sistem Pemeliharaan Sistem Pengelolaan Kotoran

Emisi N2O dari Manajemen Manur
Definition of Manure Management System Pasture/Range/Paddock The manure from pasture and range grazing animals is allowed to lie as deposited, and is not managed. Daily spread Manure is routinely removed from a confinement facility and is applied to cropland or pasture within 24 hours of excretion. Solid storage The storage of manure, typically for a period of several months, in unconfined piles or stacks. Manure is able to be stacked due to the presence of a sufficient amount of bedding material or loss of moisture by evaporation. Dry lot A paved or unpaved open confinement area without any significant vegetative cover where accumulating manure may be removed periodically
Definition of Manure Management System Liquid/Slurry Manure is stored as excreted or with some minimal addition of water in either tanks or earthen ponds outside the animal housing, usually for periods less than one year. Uncovered anaerobic lagoon A type of liquid storage system designed and operated to combine waste stabilization and storage. Lagoon supernatant is usually used to remove manure from the associated confinement facilities to the lagoon. Anaerobic lagoons are designed with varying lengths of storage (up to a year or greater), depending on the climate region, the volatile solids loading rate, and other operational factors. The water from the lagoon may be recycled as flush water or used to irrigate and fertilise fields. Pit storage below animal confinements Collection and storage of manure usually with little or no added water typically below a slatted floor in an enclosed animal confinement facility, usually for periods less than one year.
Definition of Manure Management System Anaerobic digester Animal excreta with or without straw are collected and anaerobically digested in a large containment vessel or covered lagoon. Digesters are designed and operated for waste stabilization by the microbial reduction of complex organic compounds to CO2 and CH4, which is captured and flared or used as a fuel Burned for fuel The dung and urine are excreted on fields. The sun dried dung cakes are burned for fuel. Cattle and Swine deep bedding As manure accumulates, bedding is continually added to absorb moisture over a production cycle and possibly for as long as 6 to 12 months. This manure management system also is known as a bedded pack manure management system and may be combined with a dry lot or pasture. Composting - invessel Composting, typically in an enclosed channel, with forced aeration and continuous mixing. Composting - Static pile Composting in piles with forced aeration but no mixing.
Definition of Manure Management System Composting - Intensive windrow Composting in windrows with regular (at least daily) turning for mixing and aeration. Composting - Passive Composting in windrows with infrequent turning for mixing and aeration. Poultry manure with litter Similar to cattle and swine deep bedding except usually not combined with a dry lot or pasture. Typically used for all poultry breeder flocks and for the production of meat type chickens (broilers) and other fowl. Poultry manure without litter May be similar to open pits in enclosed animal confinement facilities or may be designed and operated to dry the manure as it accumulates. The latter is known as a high-rise manure management system and is a form of passive windrow composting when designed and operated Properly Aerobic treatment The biological oxidation of manure collected as a liquid with either forced or natural aeration. Natural aeration is limited to aerobic and facultative ponds and wetland systems and is due primarily to photosynthesis. Hence, these systems typically become anoxic during periods without sunlight.

Perhitungan Populasi Ayam Broiler Pada perhitungan inventory SNC populasi ayam broiler dan ayam kampung tidak dikoreksi Populasi ayama broiler dihitung dengan mempertimbangkan masa pemeliharaan. Pada umnya ayam broiler dipelihara selama 60 hari dan ayam kampung dipelihara 120 hari. Jika pada tahun 2011 produksi Boiler ekor/tahun 1.041.968.000 ekor/th, maka rataan populasi broiler per tahun: Rataan produksi per tahun = 60 x (1.041.968/365) = 171.822.410 ekor/tahun
Koreksi Populasi Ternak Impor sapi bakalan dan kerbau masuk dalam perhitungan populasi sapi (?) Setiap tahun Indonesia masih mengimport sapi bakalan sekitar 500 ribu ekor. Sapi bakalan dipelihara hanya 4 bulan (120 hari), dengan demikian perlu dikoreksi (120/365)
Kegiatan Mitigasi Kegiatan mitigasi dalam peternakan berupa instalasi Biogas melalui BATAMAS atau BIRU dapat dihitung. Perbaikan kualitas pakan, peningkatan kualitas pastura dan peningkatan mutu genetik masih sulit untuk diperhitung.
