Judul: Analisis Perbandingan Profitabilitas Usaha Penggemukan Sapi Madura Dan Persilangan (Madura-Limousin)(Studi Kasus: Desa Banyubunih Kecamatan Galis Kabupaten Bangkalan).
Abstrak: Sapi potong merupakan salah satu komoditi unggulan dari subsektor peternakan. Salah satu bangsa sapi potong yang mempunyai potensi besar untuk memenuhi kebutuhan daging nasional adalah Sapi Madura dan persilangan Sapi Madura dengan Limousin (Madrasin). Tujuan penelitian ini adalah menganalisis perbandingan profitabilitas pada usaha penggemukan Sapi Madura dan Sapi Madrasin. Berdasarkan pengamatan pada kelompok tani ternak Harapan Jaya I Desa Banyubunih Kecamatan Galis Kabupaten Bangkalan dengan menggunakan metode purposive sampling memperoleh hasil sebagai berikut: Rata-rata perolehan nilai profitabilitas usaha penggemukan Sapi Madura mencapai 10.06 persen, sedangkan rata-rat perolehan nilai profitabilitas usaha penggemukan Sapi Madrasin sebesar 12.63 persen. Profitabilitas usaha penggemukan sapi Madrasin lebih tinggi dibandingkan usaha penggemukan Sapi Madura.

Judul: Analisis Pendapatan Usahaternak Sapi Rakyat di Madura, Jawa Timur.
Abstrak: Sebagian besar peternak sapi di Indonesia merupakan peternak rakyat. umumnya memelihara sapi kurang dari sepuluh ekor dan hanya dijadikan usaha sampingan. Penelitian ini bertujuan untuk mengetahui bagaimana penerimaan dan pendapatan peternak rakyat sapi lokal khususnya sapi Madura. Menurut masyarakat Madura, ternak sapi digunakan sebagai salah satu cara untuk menyimpan harta mereka. Peralatan yang digunakan untuk melakukan usahaternak masih sederhana. Tenaga kerja yang digunakan dominan menggunakan tenaga kerja dalam keluarga. Penelitian ini dilakukan pada bulan Januari 2016 hingga Februari 2016 di Kabupaten Pamekasan dan Kabupaten Sumenep. Metode pengumpulan data menggunakan metode purposive sampling dengan menggunakan metode analisis pendapatan, analisis R/C ratio dan menggunakan uji-t. Hasil perhitungan menyatakan bahwa, usaha penggemukan sapi lebih menguntungkan dibandingkan dengan usaha pembibitan. Peternak yang hanya memelihara satu atau dua ekor sapi hasil yang didapatkan dari usahaternaknya masih lebih rendah dibandingkan dengan UMR (Upah Minimum Regional) di daerahnya. Hasil yang diperoleh adalah peternak dapat memperoleh pendapatan minimal setara UMR (Upah Minimum Regional) apabila jumlah sapi yang dipelihara 3-7 ekor sapi.

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.
