Judul: Pengetahuan, nilai religiusitas, sikap, dan perilaku membaca label halal pada mahasiswa
Abstrak: Label halal merupakan label pada makanan yang dibenarkan menurut syariat Islam, bermutu, dan tidak membahayakan kesehatan. Penelitian ini bertujuan menganalisis pengaruh karakteristik individu, karakteristik keluarga responden, pengetahuan, nilai, dan sikap terhadap perilaku membaca label halal produk pangan pada mahasiswa Strata Satu (S-1) Institut Pertanian Bogor. Disain penelitian ini adalah cross sectional study dengan metode survei. Penelitian ini melibatkan 400 mahasiswa IPB yang dipilih menggunakan teknik multistage random sampling dengan lapis jenis kelamin. Terdapat perbedaan nyata antara laki-laki dan perempuan pada variabel pengetahuan, nilai, dan sikap dalam membaca label halal, sedangkan perilaku membaca label tidak berbeda nyata. Usia berpengaruh negatif nyata terhadap perilaku. Agama dan sikap berpengaruh positif nyata terhadap perilaku membaca label halal produk pangan., Halal label is a label on food that justified accoording to Moeslim’s syari’ah, qualified and does not harm our health. The purspose of this research was to analyzed the effect of individual characteristics, family characteristics, knowledge, value and the attitude towards behavior of reading the halal label on food products of undergraduate students of Bogor Agricultural University. This study used cross sectional study with survey method. The research involved 400 students of Bogor Agricultural University that were chosen by multistage random sampling with gender as a layer. There was significant differences between female and male in knowledge, religiosity, and attitude in reading halal label, whereas the behavior in reading label had no significant difference. Age, religion and attitude were found affected behavior of reading halal label on food products.

Judul: Analysis of Student Behavior Against Food Product Labels
Abstrak: Label pangan sangat penting untuk agribisnis pangan. Survey yang pernah dilakukan oleh Badan Perlindungan Konsumen Nasional terhadap konsumen di Indonesia tentang memperhatikan kelengkapan label produk pangan dalam beberapa tahun mengalami kenaikan namun masih tergolong rendah sehingga menunjukkan konsumen masih kurang peduli terhadap label pangan. Tujuan dari penelitian ini adalah untuk mengidentifikasi pengetahuan, persepsi, sikap, dan perilaku mahasiswa IPB terhadap label pangan dan menganalisis pengaruh pengetahuan, persepsi, sikap, dan perilaku mahasiswa S1 IPB terhadap label pangan. Penelitian ini menggunakan metode analisis deskriptif dan structural equation modeling dengan pendekatan partial least square (SEM-PLS). Hasil analisis deskriptif menunjukkan hampir seluruh responden memiliki pengetahuan awal tentang label pangan. Responden lebih banyak memperhatikan atribut harga dibandingkan label pangan. Lalu label yang sering diperhatikan oleh mahasiswa yaitu tanggal kadaluarsa dan urutan prioritas label pangan yaitu nama produk, tanggal kadaluarsa, dan label komposisi. Kemudian pengetahuan dan persepsi mahasiswa terhadap label pangan tegolong baik, sikap dan perilaku mahasiswa terhadap label produk pangan tergolong cukup baik. Hasil analisis SEM-PLS menunjukkan pengetahuan berpengaruh positif signifikan terhadap persepsi dan sikap, persepsi berpengaruh terhadap sikap, dan sikap berpengaruh terhadap perilaku mahasiswa.

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.
