Abstrak: Methane (CH,) is one of reactive greenhouse gases, its current concentration in atmosphere is increasing with a rate of about 12 + 1 ppbvlyr. An increase of 12 ppbv requires an excess of sources over sinks of 36 Tglyr. Roughly 70% of the total global emission of atmospheric methane (500 f 100 Tglyr) stems from anthropogenic sources mainly from anaerobic decay of organic matter in rice fields and enteric fermentation in ruminants, and about 30% stems from natural sources mainly frcm wetlands. Rice fields are considered as one of important sources of methane emissions into the atmosphere. Estimates of methane from this source show a wide range of 30 - 100 Tglyr with an average of about 60 Tglyr or around 18% of the total global methane emissions. There are large uncertainties about methane emission rates from wetland rice, these are due to the differences of agroclimatic condition and agricultural practices from one region to the others. Most studies on methane emission rates from rice fields are conducted in temperate regions, and practically no data are available from tropical regions. Those data obtained from temperate regions are used to extrapolate global methane emissions from rice fields.

Abstrak: National economic p w t h which is relatively high is expected to solve many problems of national development overwhelming Indonesia currently. But the negative impact is the increasing greenhouse gas emission, which followed by global warming; and hence, assumedly, it will also cause a negative impact to Indonesia as an archipelago as well as agricultural country. This study is intended primarily to observe relationship among the national economy growth, agricultural sector, and the outbreak of the most important greenhouse gas emission, namely carbon dioxide (COz), methane gas (Cb) and nitrous oxide (N20). analyses instrument used mostly is reversion matrix of Leontief through Input-Output tables of 1980, 1990, and 2000 from Indonesian Central Bureau of Statistics. The result of this study shows that the decreasing national economic growth during the three pointed yeam (1980, 1990, and 2000) had influenced at the decreasing capacity of paddy sector in creating income, added value and job opportunity; but it had not influenced in establishing output. The increasing finai demand in agricultural sector limitedly has just influenced in establishing methane gas in agricultural sector only, and slightly influenced in other sectors. With an assumption that economy grows by 5.8%, then the increasing greenhouse gas emission (GRK) established up to 5,173,124 tons, and if economy grows further, becoming 7.4%, then the increasing GRK will also raise by 28%.

Judul: Profil Hematologi Selama Proses Kesembuhan Skin Flaps H-Plasty Dan Linear Closure Pada Kucing Lokal (Felis Catus).
Abstrak: Skin flaps merupakan salah satu prosedur bedah rekonstruksi untuk penutupan luka. Tujuan penelitian ini adalah melihat profil hematologi selama proses kesembuhan luka menggunakan teknik skin flaps H˗plasty dan linear closure pada kucing (Felis catus). Pembuatan luka dengan luas 2x2 cm dilakukan pada daerah toraks 6 kucing lokal jantan sehat yang dibagi kedalam dua kelompok. Penutupan luka dilakukan dengan teknik skin flaps H-plasty dan linear closure sesuai kelompok. Pengambilan darah sebanyak 1 ml dilakukan secara aseptis pada vena saphena pada hari ke˗0 pra operasi, hari ke˗3, 6, 9, dan 12 pasca operasi skin flaps. Hasil rata-rata jumlah SDM, hemoglobin, hematokrit, MCHC, dan trombosit tidak menunjukkan perbedaan signifikan (P>0.05) antar kelompok perlakuan H-plasty dengan linear closure. Berbeda dengan parameter MCV dan MCH yang menunjukkan perbedaan signifikan (P<0.05) antar kelompok perlakuan. Pengamatan rata-rata jumlah SDM, hemoglobin, hematokrit, MCV, MCH, MCHC dan trombosit menunjukkan perbedaan yang signifikan (P<0.05) diantara hari pengamatan. Kedua teknik skin flaps menunjukkan nilai rata˗rata jumlah profil hematologi yang fisiologis selama proses kesembuhan luka.
