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%.

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.

Judul: Peran Gambaran Leukosit terhadap Kesembuhan Luka antara H-Plasty dengan Linear Closure pada Kucing Lokal (Felis catus).
Abstrak: Skin wounds commonly seen in veterinary practice can be repaired with a variety of reconstructive choices such as skin flaps. The research purpose is to learn and understand the healing process between skin flap H-Plasty and linear closure in domestic house cats by observing leukocyte profiles. Six male cats divided into two groups were used of which open wounds of 2x2 cm were made on the skin of lateral thorax. In H-Plasty group, 1 cm parallel incisions were made on each sides of the defect, skin is undermined, advanced over the defect and sutured. In linear closure group, the elliptic defect was sutured across the widest part, continued by dividing each remaining segment in half with subsequent sutures. Blood was drawn of 1 ml from the medial saphenous vein for an alternating 3 days of a 12-day period and the profiles’ results were observed. Both flaps showed insignificant differences (P>0.05) in the profiles of segmented neutrophils, lymphocytes and monocytes whereas significant differences (p<0.05) was seen in the profiles of leukocytes, banded neutrophils and eosinophils when compared between observation time. The profiles’ results were all within reference range, therefore both skin flaps can be used to close wounds.
