Judul: Pengobatan dengan PGF2a dan kombinasi enukleasi korpus luteum dengan antibiotik pada sapi perah yang kawin berulang disertai identifikasi kuman kuman uterus
Abstrak: Tujuan penelitian ini adalah untuk mengetahui hasil pengobatan dengan PGF2a dan kombinasi enukleasi korpus luteum dengan antibiotik pada sapi perah yang kawin berulang terhadap timbulnya gejala berahi dan kebuntingan serta identifikasi kuman-kuman dari uterus yar1g diduga sebagai penyebabnya. Sapi perah bangsa FH akseptor inseminasi buatan yang kawin berulang sebanyak 44 ekor digunakan dalam penelitian ini. Untuk percobaan pengobatan sebanyak 28 ekor diobati dengan PGF2a (Enzaprost-F), dosis 2 ml (8 mg) diberikan secara intra uterin dan sisanya sebanyak 16 ekor diobati dengan kombinasi enukleasi korpus luteum dengan antibiotik (Terramycin-100), dosis 10 ml (1000 mg) diberikansecara intra muskuler. Berahi yang timbul setelah pengobatan diamati dan terjadinya kebuntingan ditentukan dengan palpasi rektal 60 sampai 90 hari setelah inseminasi. Spesimen untuk pemeriksaan kuman yang diperoleh, berupa bilasan uterus sapi perah yang diambil dengan kateter mini secara aseptik dengan metoda rectovaginal.

Judul: Pengaruh pengobatan/rangsangan berahi dengan penstap PGF2 terhadap kebuntingan dan identifikasi human dari uterus sapi brahman kawin berulang
Abstrak: Hasil penelitian menunjukkan bahwa : Penstrep PGF 24 Pengobatan dengan menjadi berahi sebanyak 14 ekor (93.33%) dan bunting delapan ekor (53.33%). Pengobatan dengan PGF menjadi berahi 13 ekor (86.67%) dan bunting dua ekor (13.22%). Uji statistik menunjukkan bahwa pengaruh pengobatan sampai terjadi berahi oleh PGF2+ antibiotik dan PGF2 saja pada taraf nyata lima persen tidak berbeda nyata, sedangkan sampai terjadi kebuntingan berbeda nyata. Identifikasi kuman-kuman dari uterus sapi Brahman yang kawin berulang diperoleh kelompok isolat Gram positif yaitu : Gram positif 37 isolat yaitu : Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus pyogenes, Bacillus sp., Streptococcus faecalis dan Streptococcus agalactiae. Gram negatif 32 isolat yaitu : Escherichia coli, Alkaligenes faecalis, Neisseria mucosa, Actinobacillus lignierrisii, Pseudomonas aerugenosa dan Gemella sp. Uji kepekaan isolat secara in vitro menunjukkan bahwa rata-rata semua isolat peka terhadap antibiotik yang digunakan. Persentase kepekaan pada masing-masing antibiotik ada- Ampicillin (91.6%), Oxytetracyclin (91.6%), Kanamycin (83.3%), Penicillin (75.0%), Cloramphenicol (66.7%), Streptomycin (66.7%). Dari hasil penelitian ini dapat disimpulkan bahwa hasil pengobatan Penstrep + PGF, 24 lebih baik daripada hanya dengan PGF untuk sapi Brahman kawin ulang. ...

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
