Judul: Analisis pemasaran ayam broiler pada kelompok peternak plasma "jaya broiler" kabupaten Kuningan propinsi Jawa Barat
Abstrak: Pemasaran merupakan suatu hal untuk menilai berhasil atau tidaknya usaha yang dijalankan. Tujuan akhir dari proses produksi adalah untuk dipasarkan atau dijual dengan harapan mendapat imbalan berupa penghasilan atau keuntungan yang memadai. Kenyataannya harga yang diterima oleh petemak kecil masih jauh lebih rendah dari harga yang dibayar oleh konsumen akhir. Tujuan penelitian ini adalah untuk mengetahui bentuk keIjasama inti-plasma, saluran dan fungsi pemasaran, mengetahui biaya pemasaran, marjin pemasaran dan efisiensi pemasaran ayam broiler di Kabupaten Kuningan.

Judul: Analisis pendapatan peternak ayam ras pedaging pola kemitraan inti-plasma (Studi kasus peternak plasma dari tunas mekar farm di kecamatan Nanggung kabupaten Bogor, Jawa Barat)
Abstrak: Ayam broiler merupakan ayam penghasil daging yang memiliki beberapa keunggulan diantaranya, laju perputaran modal yang cepat dan waktu pemeliharaan yang singkat yaitu dalam lima minggu ayam broiler sudah dapat dipanen dengan bobot 1,5 kg/ekor. Hal inilah yang mendorong banyak peternak yang mengusahakan peternakan ayam broiler. Tunas Mekar Farm adalah salah satu perusahaan peternakan ayam broiler yang melakukan kerjasama dengan peternak di Kecamatan Nanggung melalui pola kemitraan inti-plasama. Tujuan pola kemitraan ini adalah meningkatkan pendapatan, dan peningkatan skala usaha baik dari pihak perusahaan maupun peternak. Tujuan dari penelitian ini adalah untuk menganalisis mekanisme kemitraan yang dilakukan pada pola kemitraan inti-plasma, mengetahui manajemen pemeliharaan (budidaya) ternak pada pola kemitraan inti-plasma, dan menghitung pendapatan dan nilai R/C Rasio yang didapat peternak plasma pada pola kemitraan inti-plasma.

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.
