Judul: Kasus Mastitis Subklinis pada Kambing Perah di PT. Taurus Dairy Farm Sqkabumi, Menggunakan Pereaksi IPB-1 dan Metode Breed.
Abstrak: Salah satu sumber protein hewani yang mudah dikembangbiakkan adalah ternak kambing. Disamping dagingnya, ternak kambing juga menghasilkan susu yang berguna untulc kesehatan tubuh. Susu kambing sebagai minuman yang bergizi tinggi maka sudah selayaknya hams dipasarkan dengan bersih, sehat dan bebas dari kuman-kuman patogen serta bakteri (Murtidjo, 1 993). Susu tersebut terutama diperoleh dari kambing perah yang sehat dengan penanganan yang baik mulai dari pemerahan sampai pemasaran.

Judul: Perbandingan Uji Mastitis IPB-1 dengan Metode Breed untuk Diagnosa Mastitis Subklinis pada Susu Kerbau dan Susu Kambing
Abstrak: Kejadian mastitis subklinis mengakibatkan turunnya produksi dan kualitas susu yang tidak hanya terjadi pada sapi perah, tetapi juga pada kerbau dan kambing perah. Tujuan penelitian ini adalah untuk mengetahui perbandingan antara uji mastitis IPB-1 dengan metode Breed untuk diagnosa mastitis subklinis pada susu kerbau dan susu kambing berdasarkan jumlah sel somatis. Penelitian ini dilakukan menggunakan 42 sampel susu kerbau Murrah dan 20 sampel susu kambing dengan metode langsung dan tidak langsung. Metode langsung dilakukan menghitung jumlah sel somatis didalam susu menggunakan metode Breed, sedangkan metode tidak langsung dilakukan melihat reaksi yang terbentuk antara pereaksi IPB-1 dengan susu. Hasil uji menunjukkan 28 dari 42 sampel (66.67%) susu kerbau Murrah dan 13 dari 20 sampel susu kambing (65%) yang diuji dengan metode Breed berasal dari ternak yang mengalami mastitis subklinis dan dengan uji mastitis IPB-1 menunjukkan 27 dari 42 sampel (64.28%) sampel susu kerbau Murrah dan 10 dari 20 sampel (50%) susu kambing menunjukkan reaksi positif. Penelitian ini juga menunjukkan uji mastitis IPB-1 mempunyai tingkat sensitivitas 96% dan spesifisitas 100% terhadap susu kerbau Murrah dan sensitivitas 71% dan spesifisitas 100% terhadap susu kambing. Uji mastitis IPB-1 dapat digunakan sebagai uji cepat untuk mendiagnosa mastitis subklinis lebih dini dengan cepat dan mudah pada susu kerbau Murrah dan susu kambing.

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.
