Judul: Pengaruh Pengetahuan dan Kesadaran Konsumen terhadap Perilaku Pembelian Pangan Halal
Abstrak: Indonesia merupakan sebuah negara dengan mayoritas populasi penduduk muslim yang terus meningkat. Hal ini menyebabkan semakin meningkatnya kebutuhan akan pangan halal. Tujuan dari penelitian ini adalah: 1) mengidentifikasi tingkat pengetahuan, kesadaran, dan perilaku pembelian pangan halal; dan 2) menganalisis pengaruh pengetahuan dan kesadaran terhadap perilaku pembelian pangan halal. Lokasi penelitian terdapat di Kelurahan Pasir Jaya dan Kelurahan Kedung Badak, Kota Bogor. Penelitian ini menggunakan metode survey dengan melibatkan 250 ibu rumah tangga yang dipilih secara proportional random sampling. Data dianalisis menggunakan regresi linier berganda dan analisis faktor. Hasil menunjukkan bahwa tingkat pengetahuan konsumen baik dan tingkat kesadaran konsumen sedang, sedangkan perilaku pembelian pangan halal rendah. Semakin tinggi tingkat pendidikan, kesadaran dan pengeluaran akan meningkatkan perilaku pembelian pangan halal.

Judul: Pengaruh Label Halal Terhadap Pembelian Konsumen Muslim Pada Restoran Cepat Saji Di Kota Bogor
Abstrak: Umat muslim diwajibkan untuk mengonsumsi pangan yang halal. Selain karena perintah agama, mengonsumsi makanan yang halal juga baik untuk kesehatan. Masih adanya penemuan bahan haram pada makanan, label halal pada produk pangan menjadi indikator yang penting dalam menentukan kehalalan. Penelitian ini mengidentifikasi persepsi konsumen muslim mengenai pangan halal dan lembaga halal pada produk pangan, mengidentifikasi tingkat pengetahuan konsumen muslim mengenai kehalalan suatu produk pangan, serta menganalisis pengaruh label halal terhadap keputusan pembelian pada produk pangan restoran cepat saji di Kota Bogor. Jumlah sampel yang digunakan adalah sebanyak 100 orang pada empat restoran cepat saji berlabel halal di Kota Bogor. Sampel dipilih menggunakan metode non-probability sampling. Analisis deskriptif digunakan untuk mengidentifikasi persepsi konsumen muslim mengenai pangan halal dan lembaga halal pada produk pangan serta tingkat pengetahuan konsumen muslim mengenai kehalalan suatu produk pangan. Partial Least Square Path Modeling (PLS-PM) digunakan untuk menganalisis pengaruh label halal terhadap keputusan pembelian. Persepsi konsumen muslim mengenai pangan halal dan lembaga halal pada produk pangan serta tingkat pengetahuan konsumen muslim mengenai kehalalan suatu produk pangan sudah cukup baik. Hasil Partial Least Square Path Modeling (PLS-PM) menunjukkan bahwa label halal berpengaruh signifikan dan positif terhadap keputusan pembelian pada konsumen muslim.

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.
