Judul: FINANCIAL FEASIBILITY ANALYSIS OF QURBAN BUSINESS IN FATTING OF SHEEP IN THE ALAM SEJATERA FARM
Abstrak: Domba merupakan salah satu ternak kelompok ruminansia yang memiliki rata-rata laju pertumbuhan populasi yang terus meningkat dan banyak dipelihara sebagai ternak penggemukkan. Domba penggemukkan banyak dijual pada hariraya Idul Adha dikarenakan permintaan pasar yang tinggi serta harga jual yang tinggi. Penelitian ini bertujuan menganalisis tingkat kelayakan finansial usaha qurban penggemukan domba Alam Sejahtera Farm yang berlokasi di Kabupaten Tangerang, dan menganalisis ROI investor. Nilai BEP jumlah domba adalah 53 ekor dengan penjualan menggunakan harga rata rata jual, nilai BEP harga Rp1.736.930, nilaiB/C ratio 1,23 dan nilai ROI investor 23,25%. Data-data tersebut didapatkan pada tahun 2020 yang merupakan data penggemukan yang berlangsung selama 2 bulan. Hasil yang diperoleh menunjukkan bahwa pada usaha penggemukan domba menguntungkan dan bisnis tersebut sangat cocok untuk terus dijalankan., Sheep are one of the ruminant livestock groups that have an average population growth rate that continues to increase and mostly to kept as fattening livestock. Farmers in fattening sheep are usually focused to be soldin Idul Adha, the consideration are the demands of market place and the higher price. This study aimed to analyze the level of feasibility of the AlamSejahtera Farm sheep fattening business located in Kabupaten Tangerang and to analyst the ROI Investor. Sheep BEP value is 53 tails, BEP value of Rp1.736.930, B/C ratio value of 1,23, and investor ROI value of 23,25%. These data are data obtained in 2020 which fattening lasts for 2 months. The results obtained show that sheep fattening is profitable and the business very suitable to be continue.

Judul: Analisis Kelayakan Finansial Usaha Penggemukan Domba di Peternakan Saudagar Embe Farm
Abstrak: Usaha penggemukan domba merupakan usaha yang banyak dijalankan oleh peternak karena perputaran uangnya cepat dibandingkan usaha pembiakan. Domba yang digemukkan akan dijual untuk qurban, karena harga jualnya lebih tinggi dibandingkan dengan hari biasa. Penelitian ini bertujuan menganalisis tingkat kelayakan finansial usaha penggemukan domba Saudagar Embe Farm yang berlokasi di Desa Sarampad Kecamatan Cugenang Kabupaten Cianjur. Metode penelitian yaitu pengisian kuisioner oleh pengelola Saudagar Embe Farm. Analisis yang dilakukan yaitu BEP, B/C ratio, dan ROI. Nilai BEP domba yaitu 216 ekor, nilai BEP harga Rp2 112 273. nilai B/C ratio 1.32, dan nilai ROI investor 12.78 %. Data-data tersebut merupakan data yang didapatkan di tahun 2019 yang penggemukannya berlangsung selama 6 bulan. Hasil yang diperoleh menunjukkan usaha penggemukan domba menguntungkan dan layak untuk dilanjutkan.

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.
