Judul: Gambaran Eritrosit Anjing Beagle terinfestasi Caplak Rhipicephalus sanguineus yang Diobati dengan Obat Berbahan Aktif Fluralaner Tiga Kali Dosis.
Abstrak: Anjing merupakan hewan kesayangan yang sering dipelihara manusia. Salah satu kendala memelihara anjing yaitu masalah ektoparasit seperti infestasi caplak Rhipicephalus sanguineus. Salah satu bentuk pengendalian ektoparasit yaitu dengan pemberian obat berbahan aktif fluralaner. Fluralaner merupakan pestisida dengan potensi tinggi untuk membunuh caplak secara sistemik. Penelitian ini dilakukan untuk mengetahui dan mempelajari gambaran eritrosit anjing yang terinfestasi caplak Rhipicephalus sanguineus yang diobati dengan obat berbahan aktif fluralaner tiga kali dosis. Anjing yang digunakan yaitu 3 ekor anjing ras beagle dengan umur 1-6 tahun dan berat badan antara 8.5-10 kg. Sample darah diambil melalui vena cephalica accessoria pada 24 jam pre-treatment, 24 jam, 4 minggu, 8 minggu, dan 12 minggu post-treatment untuk dianalisis total eritrosit, hemoglobin, hematokrit, dan indeks eritrosit (MCH, MCV, dan MCHC). Hasil pengamatan menunjukkan terjadi perubahan signifikan (P<0,05) total eritrosit, hemoglobin, hematokrit, dan MCHC serta tidak terjadi perubahan signifikan (P>0,05) MCV dan MCH pada pre dan post-treatment. Namun demikian, perubahan yang signifikan pada eritrosit bukan disebabkan oleh pemberian fluralaner, tetapi kemungkinan karena adanya infestasi parasit darah pada anjing.

Judul: Profil Eritrogram Anjing Terinfestasi Caplak Rhipicephalus sanguineus yang Diobati dengan Sediaan Fluralaner.
Abstrak: Sediaan fluralaner merupakan obat kunyah anticaplak terbaru dengan isoxazoline sebagai struktur utamanya. Sediaan ini terbukti efektif membunuh caplak Rhipicephalus sanguineus pada anjing sampai dengan 12 minggu setelah pemberian satu kali dosis yang dianjurkan, namun belum ada laporan mengenai pengaruhnya terhadap profil eritrogram. Penelitian ini mengevaluasi profil eritogram sembilan ekor anjing sebelum pemberian sediaan, empat jam setelah pemberian sediaan, serta pada 28, 56, serta 84 hari setelah pemberian sediaan fluralaner. Mesin hematology analyzer digunakan untuk memeriksa parameter berupa jumlah eritrosit, kadar hemoglobin, nilai hematokrit, serta indeks eritrosit. Hasil penelitian menunjukkan bahwa sediaan fluralaner mampu memperbaiki kondisi anemia pada anjing terinfestasi caplak yang ditunjukkan dengan perubahan jumlah eritrosit, nilai hematokrit, serta indeks eritrosit yang mendekati nilai normal pada hari ke-84.

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.
