Judul: Pengetahuan tentang Alergi Makanan dan Alergen Pangan, Persepsi, Sikap, dan Perilaku Membaca Label Produk Pangan Olahan Beralergen pada Mahasiswa
Abstrak: Perubahan kebiasaan makan khususnya pangan olahan dapat meningkatkan risiko terjadinya reaksi alergi makanan pada individu dengan status alergi makanan. Label informasi alergen menjadi hal yang penting dalam upaya pencegahan terjadinya reaksi alergi. Penelitian ini bertujuan untuk menganalisis pengetahuan, persepsi, sikap, dan perilaku membaca label produk pangan olahan beralergen pada mahasiswa. Desain penelitian menggunakan cross-sectional study dengan jumlah contoh sebesar 94 orang yang dipilih secara acak. Contoh dibagi ke dalam dua kelompok, yaitu kelompok alergi makanan dan kelompok tidak alergi makanan dengan jumlah contoh dalam masing-masing kelompok 47 orang. Status alergi contoh ditentukan berdasarkan pernyataan contoh tentang adanya reaksi alergi makanan atau diagnosis formal yang diterima contoh. Data yang digunakan berupa data primer yang diperoleh secara langsung melalui penyebaran kuesioner. Penelitian ini dilaksanakan pada bulan Maret-Juni 2017. Hasil penelitian menunjukkan bahwa kedua kelompok contoh termasuk berpengetahuan kurang (80.85%), persepsi termasuk kategori cukup (64.9%), sikap termasuk kategori cukup (69.1%), dan perilaku termasuk kategori cukup (72.3%). Uji korelasi menunjukkan adanya hubungan yang signifikan (p<0.05) antara status alergi dengan sikap; usia dengan perilaku; pendidikan orang tua dengan persepsi dan sikap pada kelompok alergi makanan; pendidikan ayah dengan perilaku; pengetahuan dengan sikap pada kelompok alergi makanan; serta persepsi, sikap, dan perilaku membaca label produk pangan olahan beralergen.

Judul: Pengetahuan, persepsi, sikap, dan perilaku membaca label informasi gizi pada mahasiswa
Abstrak: Label informasi gizi merupakan label yang memuat informasi mengenai kandungan gizi di dalam produk pangan yang menjadi media sangat penting untuk mentransfer informasi mengenai karakteristik dari suatu produk pangan. Tujuan penelitian ini adalah untuk menganalisis pengaruh karakteristik individu, karakteristik keluarga, pengetahuan, persepsi, dan sikap terhadap perilaku membaca label informasi gizi produk pangan pada mahasiswa Strata Satu (S1) Institut Pertanian Bogor. Disain penelitian ini menggunakan cross sectional study dengan metode survei yang dilakukan di Kampus Institut Pertanian Bogor (IPB), Kecamatan Dramaga, Kabupaten Bogor. Penelitian ini melibatkan 400 mahasiswa IPB yang dipilih dengan menggunakan teknik multistage random sampling dengan lapis jenis kelamin. Terdapat perbedaan nyata antara responden laki-laki dan perempuan dalam hal pengetahuan, sedangkan persepsi, sikap, dan perilaku membaca label informasi gizi tidak berbeda nyata. Sikap berpengaruh nyata terhadap perilaku membaca label informasi gizi., Nutrition labels is a label that contains information about nutrition in a food product which become very important media to transferring information about characteristic in a food product. The aim of this research was to analyze the effect of individuals characteristics, family’s characteristics, knowledge, perception, and attitude on reading behavior of nutrition labels of undergraduate students of Bogor Agricultural University. The design of this research used cross sectional study with survey method which conducted in Bogor Agricultural University, Dramaga district, Bogor regency. This research involved 400 Bogor Agricultural University’s students selected by multistage random sampling based on gender. There was significant difference between male and female for knowledge, meanwhile the difference was not appear significant for perception, attitude, and reading behavior of nutrition labels. Attitude influenced on reading behavior of nutrition labels.

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.
