Judul: Profil Eritrosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Afoxolaner banyak digunakan untuk mengobati dan mencegah infestasi caplak pada anjing. Senyawa tersebut memiliki efektivitas yang tinggi dan mampu mencegah reinfestasi sebulan sejak diberikan. Hingga saat ini belum diketahui efek afoxolaner terhadap profil eritrosit anjing. Afoxolaner diberikan kepada enam anjing beagle (8-12 bulan) yang secara klinis tidak terinfestasi caplak. Anjing dibagi menjadi dua kelompok perlakuan yang berbeda. Kelompok 1 diberikan sediaan afoxolaner sebanyak satu kali dosis anjuran sementara kelompok 2 diberikan lima kali dosis anjuran. Pemberian sediaan afoxolaner dilakukan sebulan sekali sebanyak tiga kali pengulangan dengan jarak antar pemberian satu bulan. Sampel darah diuji menggunakan hematology analyzer MEK-6450 dan data dianalisis menggunakan perangkat lunak SPSS 16.0. Hasil yang didapat menunjukkan bahwa secara statistik tidak ada perubahan signifikan antara profil eritrosit anjing beagle sebelum dan sesudah pemberian sediaan afoxolaner. Disimpulkan bahwa pemberian sediaan afoxolaner lima kali dosis anjuran secara oral tidak memengaruhi profil eritrosit anjing beagle.

Judul: Profil Leukosit Anjing Beagle Setelah Pemberian Obat Anti Caplak Afoxolaner Lima Kali Dosis.
Abstrak: Penelitian ini bertujuan mengetahui profil leukosit anjing beagle setelah pemberian obat anti caplak afoxolaner dengan dosis 1 dan 5 kali dari dosis yang dianjurkan. Penelitian ini menggunakan enam ekor anjing ras beagle yang dibagi menjadi dua kelompok, yaitu kelompok dosis satu kali dan kelompok dosis lima kali. Masing-masing kelompok terdiri atas tiga ekor anjing. Kelompok dosis satu kali diberi afoxolaner dengan dosis 6,3 mg/kg BB, sedangkan kelompok dosis lima kali diberi afoxolaner dengan dosis 31,5 mg/kg BB. Masing-masing perlakuan diberikan sediaan afoxolaner secara per oral dengan frekuensi tiga kali selama 2 bulan, yakni pada hari ke 1, 28, dan 56. Sediaan darah diperiksa dengan alat Hematology Analyzer (Celltac Alpha® type MEK 6450K produksi Nihon Kohden) berupa parameter (leukosit, limfosit, dan granulosit). Selanjutnya data dianalisis menggunakan program Statistical Products and Solution Services version 25 (SPSS V.25). Hasil penelitian menunjukkan bahwa terdapat kenaikan atau penurunan beberapa nilai parameter. Namun, secara statistik menunjukkan tidak adanya perbedaan yang signifikan dari nilai rata-rata semua parameter antar ke 2 kelompok perlakuan. Hal tersebut menandakan pemberian sediaan afoxolaner tidak mempengaruhi faal leukosit anjing sampai lima kali dosis.

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.
