Industri Feedlot Indonesia
Abstrak: Daging merupakan komoditas utama yang diperdagangkan di seluruh dunia karena bernilai ekonomis dan bernutrisi. Sayangnya, peternakan rakyat di Indonesia belum mampu merespon permintaan daging sapi terlihat dari level impor tinggi sehingga feedlot memiliki peran penting dalam penyediaan komoditas tersebut melalui teknologi yang lebih baik. Namun, masih dipertanyakan bilamana industri feedlot Indonesia memiliki keunggulan komparatif dan kompetitif. Selain itu, belum diketahui pula apakah kebijakan yang diterapkan mendukung daya saing feedlot Indonesia. Oleh sebab itu, studi ini bertujuan untuk menilai keunggulan komparatif dan kompetitif industri feedlot indonesia serta mengevaluasi kebijakan pemerintah terkait daging dan sapi potong. Untuk mengukurnya, studi ini meliputi tiga provinsi yang menjadi produsen dan konsumen utama daging di Indonesia, yaitu Banten, Lampung, dan Jawa Barat. Keunggulan komparatif dan kompetitif serta dampak kebijakan terhadap industri feedlot Indonesia dianalisis menggunakan Policy Analysis Matrix (PAM). Penelitian ini menunjukkan bahwa feedlot memiliki keunggulan komparatif dan keunggulan kompetitif dinilai dari nilai DRC dan PRC kurang dari satu. Selain itu, kebijakan pemerintah telah mendukung tercapainya keunggulan komparatif dan keunggulan kompetitif industri feedlot Indonesia. Hal ini dibuktikan melalui analisis kebijakan pemerintah terhadap input dan output sapi potong. Kebijakan input dan output telah cukup memproteksi dan melindungi usaha sapi potong, sehingga pelaku usaha feedlot di Banten, Lampung, dan Jawa Barat memperoleh keuntungan berturut-turut sebesar 1 437 964, 1 763 357, and 1 196 335 IDR/ekor. Adanya kebijakan input dan output sapi potong meningkatkam nilai tambah keuntungan serta memberikan dampak positif terhadap biaya produksi, sebab menurunkan biaya produksi sebanyak 16 persen untuk Banten, 19 persen untuk Lampung, dan 13 persen untuk Jawa Barat. Lebih jauh, hasil analisis sensitifitas menjelaskan bahwa harga sapi bakalan berpengaruh terhadap daya saing.

Judul: Analisis Daya Saing Industri Penggemukan Sapi Potong Lokal di Indonesia
Abstrak: The competitiveness of the local cattle industry is analyzed to determine the direction and development of supporting factors to achieve meat self-sufficiency program in 20 priority areas of local beef cattle. Methode used is the Industrial Competitiveness Index (ICI) which aims to combine multidimensional economic performance including profitability, productivity, and output growth, using 1999-2010 data series. The results show that the profitability and productivity of local cattle feedlot industry is not efficient and effective way to cultivate despite an upward trend. This caused the low competitiveness of feedlot industries of local beef cattle. Condition of low competitiveness is empirically illustrate that the local cattle feedlot industry is still not capable to achieve self-sufficiency of meat in the short term.

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.
