Judul: Feasibility analysis of fattening beef cattle in pt prisma mahesa unggul kecamatan babakan madang kabupaten bogor
Abstrak: PT Prisma Mahesa Unggul merupakan salah satu bisnis penggemukan sapi potong. Tujuan dari penelitian ini adalah untuk menganalisis kelayakan bisnis penggemukan sapi potong dari aspek finansial dan non finansial. Metode analisis yang digunakan dalam penelitian ini adalah analisis kualitatif dan kuantitatif. Analisis kualitatif digunakan untuk melihat kelayakan bisnis dari aspek non finansial, yaitu aspek pasar, teknis, manajemen dan hukum, sosial dan ekonomi, serta lingkungan. Analisis kuantitatif digunakan untuk melihat kelayakan bisnis dari aspek finansial dengan menggunakan beberapa kriteria investasi serta analisis sensitivitas. Kriteria investasi yang digunakan adalah NPV, IRR, Net B/C, serta payback period. Nilai NPV yang diperoleh sebesar 35 879 286 506, IRR sebesar 36 persen, Net B/C sebesar 3.312, dan payback period selama lima tahun tiga bulan dua puluh delapan hari. Berdasarkan kedua aspek, bisnis penggemukan sapi potong PT Prisma Mahesa Unggul ini layak untuk dijalankan kecuali pada aspek teknis dan lingkungan karena pembersihan kandang dilakukan selama satu bulan sekali dan pengolahan limbah cair belum dilakukan secara tepat. Berdasar analisis sensitivitas, penurunan bobot sapi lebih peka dibandingkan dengan kenaikan harga sapi bakalan., PT Prisma Mahesa Unggul is one of fattening beef cattle bussiness. The purpose of this research is to analyze the feasibility of fattening beef cattle in financial and non-financial aspects. Data analysis methods used are qualitative and quantitative. Qualitative analysis used to analyze non-financial aspects such as market aspects, technical, management and legal, social and economic, and environmental. Quantitative analysis used to analyze the financial aspects using multiple investment criteria and sensitivity analysis. Investment criteria used are NPV, IRR, Net B/C, and payback period. The value of NPV is Rp 35 970 988 334, an IRR is 36 percent, Net B/C is 3.318, and the payback period is for five years and three months and twenty-six days. Based on the two aspects, fattening beef cattle in PT Prisma Mahesa Unggul is feasible to run, except the technical and environmental aspects because cleaning cages did once a month and waste water treatment has not been done properly. Based on the sensitivity analysis, weight reduction of cow more sensitive than the price increased of feeder cattle.

Judul: Analisis Kelayakan Bisnis Penggemukan Sapi Potong pada PT Catur Mitra Taruma Desa Cariu Kecamatan Cariu Kabupaten Bogor
Abstrak: Terdapat kesenjangan antara jumlah konsumsi daging sapi dengan jumlah produksi daging sapi nasional. Kesenjangan tersebut membuka peluang untuk bisnis penggemukan sapi potong. PT Catur Mitra Taruma melihat peluang tersebut dan membuka bisnis penggemukan sapi potong pada bulan Maret 2010. Tujuan dari penelitian ini adalah untuk menganalisis kelayakan bisnis penggemukan sapi potong pada PT Catur Mitra Taruma. Lokasi penelitian dilakukan di kantor pusat PT Catur Mitra Taruma di Jakarta Selatan dan di lokasi kandang penggemukan di Desa Cariu Kabupaten Bogor. Metode analisis data yang digunakan dalam penelitian ini adalah analisis kualitatif dan kuantitatif. Analisis kualitatif digunakan untuk menilai kelayakan bisnis berdasarkan aspek non finansial berupa aspek pasar, aspek teknis, aspek manajemen dan hukum, dan aspek sosial, ekonomi, dan lingkungan. Analisis kuantitatif berdasarkan kriteria penilaian investasi dan analisis sensitivitas mengunakan switching value digunakan untuk menilai kelayakan bisnis aspek finansial. Hasil analisis yang diperoleh, bisnis penggemukan sapi potong pada PT Catur Mitra Taruma layak untuk dijalankan baik berdasarkan aspek nonfinansial maupun aspek finansial. Berdasarkan analisis sensitivitas menggunakan switching value, komponen volume penjualan sapi siap potong lebih peka terhadap perubahan dibandingkan komponen biaya pakan konsentrat.

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.
