Judul: Infestasi Kutu Pada Kerbau Albino (Bubalus Bubalis) Di Desa Sukamaju, Kecamatan Ciampea, Kabupaten Bogor
Abstrak: Penelitian ini bertujuan untuk mengetahui keragaman jenis dan mengukur derajat infestasi kutu serta pengaruh berkubang terhadap infestasi kutu pada kerbau albino di peternakan kerbau Desa Sukamaju, Kecamatan Ciampea, Kabupaten Bogor, Jawa Barat. Koleksi kutu menggunakan metode pengambilan secara manual dan pengukuran derajat infestasi kutu berdasarkan jumlah kutu pada beberapa regio tubuh kerbau yang dilakukan sebelum dan sesudah berkubang. Kutu yang dikoleksi dipreservasi ke dalam preparat kaca untuk proses identifikasi. Total kerbau albino yang diteliti sebanyak 10 ekor dengan pembagian 8 regio tubuh yang terdiri atas regio I (kepala), II (leher), III (dada), IV (abdomen 1), V (abdomen 2), VI (punggung), VII (ekor), dan VIII (kaki). Jenis kutu yang diperoleh hanya satu jenis yaitu Haematopinus tuberculatus (Phthiraptera: Haematopinidae). Infestasi kutu sebelum berkubang terdapat pada regio VIII (kaki) sebesar 21.89%. Penurunan infestasi kutu tertinggi akibat aktivitas berkubang terdapat pada regio VI (punggung) sebesar 8.34%. Hasil analisis Wilcoxon menunjukkan penurunan derajat infestasi kutu yang signifikan sebelum dan sesudah berkubang.

Judul: Studi Kasus Skabies Kerbau di Desa Sukamaju Kecamatan Ciampea Kabupaten Bogor.
Abstrak: Penyakit parasitik merupakan satu diantara faktor yang dapat menurunkan produktivitas ternak. Kajian ini dilakukan untuk mengidentifikasi penyebab kasus skabies pada kerbau meliputi jenis tungau yang menyerang, gejala klinis yang menyertai, serta menghitung prevalensinya. Kerbau yang berjumlah 12 ekor diamati melalui pemeriksaan klinis, dilanjutkan dengan pemeriksaan laboratorium dan pembuatan slide preparat tungau sebelum dilakukan identifikasi. Hasil penelitian menunjukkan bahwa berdasarkan pemeriksaan klinis terdapat 2 dari 12 ekor kerbau yang menunjukkan gejala klinis skabies. Jenis tungau yang menyerang adalah jenis Sarcoptes scabiei. Gejala klinis skabies pada anak kerbau adalah alopesia, hiperemi, kaheksia, anoreksia, pruritus, dan penebalan. Sementara itu, pada kerbau dewasa gejalanya adalah alopesia, hiperemi, keropeng, pruritus dan penebalan kulit. Prevalensi kasus skabies pada kerbau di Desa Sukamaju, Kecamatan Ciampea, Kabupaten Bogor adalah 16,6%.

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.
