Judul: The Willingness to Pay Analysis Against Halal Certification Steakhouse
Abstrak: Saat ini sudah banyak restoran yang menyediakan menu makanan dengan bahan dasar daging, salah satunya steakhouse. Akan tetapi masih banyak steakhouse yang belum memiliki sertifikat halal MUI. Steakhouse yang telah memiliki sertifikat halal akan memiliki harga produk yang lebih mahal jika dibandingkan dengan steakhouse yang belum memiliki sertifikat halal. Penelitian ini bertujuan untuk mengetahui nilai dan faktor yang mempengaruhi wilingness to pay konsumen Holycow! Steakhouse by Chef Afit di wilayah Jabodetabek terhadap steakhouse bersertifikat halal. Variabel yang digunakan dalam penelitian ini adalah halal awareness, halal label, religiousity, dan food quality. Penelitian ini menggunakan metode analisis Structural Equation Model (SEM) dan Contingent Valuation Method (CVM). Hasil dari penelitian ini menunjukkan bahwa variabel halal awareness, halal label, religiousity, dan food quality berpengaruh positif signifikan terhadap willingness to pay. WTP juga memberikan pengaruh positif signifikan terhadap demand on halal certfication. Berdasarkan analisis yang telah dilakukan nilai rataan WTP (EWTP) yang bersedia dibayarkan konsumen terhadap steakhouse bersertifikat halal adalah sebesar Rp15 030.

Judul: The Willingness to Pay Analysis of Bogor Regency Housewives Against Certified Halal Beef
Abstrak: Permintaan masyarakat Indonesia terhadap daging sapi dan olahannya meningkat dalam beberapa tahun terakhir. Penelitian ini bertujuan untuk menganalisis nilai dan faktor yang memengaruhi Willingness to Pay Ibu rumah tangga di Kabupaten Bogor terhadap daging sapi yang telah memiliki sertifikat halal. Objek penelitian ini adalah Ibu rumah tangga yang berdomisili di Kabupaten Bogor. Variabel-variabel yang digunakan dalam penelitian ini adalah pengetahuan terhadap daging halal, kepedulian terhadap sertifikasi halal, frekuensi pembelian, dan pendapatan. Metode analisis yang digunakan dalam penelitian ini adalah analisis regresi linier berganda dan Contingent Valuation Methods. Hasil dari penelitian ini menunjukkan bahwa nilai rataan (EWTP) kesediaan konsumen terhadap daging sapi bersertifikat halal adalah sebesar Rp 15 260. Variabel pengetahuan terhadap daging halal, kepedulian terhadap sertifikat halal, dan pendapatan berpengaruh positif dan signifikan terhadap besarnya nilai Willingness to Pay daging sapi bersertifikat halal, sedangkan variabel frekuensi pembelian tidak memiliki pengaruh yang signifikan., The demand of Indonesian people for beef and its processed products has increased in specified years. This study aims to determine the value and factors that influence Wilingness to Pay for housewives in Bogor Regency towards beef that has halal certificates. The object of this research is housewifes who live in Bogor Regency. The variables used in this study are knowledge of halal meat, concern for halal certification, frequency of purchase, and income. The analysis method used in this study is multiple linear regression analysis and Contingent Valuation Methods. The results of this study indicate that the average value (EWTP) of consumers' willingness to pay for halal certified beef is IDR 15 260. Knowledge about halal meat, concern for halal certificates, and income have a positive and significant effect on the value of Willingness to Pay for halal certified beef, while the purchase frequency variable does not have a significant effect.

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.
