Judul: Keragaan Tingkat Keanekaragaman Konsumsi Pangan, Tingkat Kecukupan Gizi, dan Status Gizi Mahasiswa Gizi IPB.
Abstrak: Penelitian ini bertujuan untuk menganalisis tingkat keanekaragaman konsumsi pangan, tingkat kecukupan gizi, dan status gizi mahasiswa Program Studi Ilmu Gizi IPB. Desain penelitian yang digunakan adalah cross sectional study dengan menggunakan data primer. Subyek dalam penelitian ini adalah mahasiswa Program Studi Ilmu Gizi IPB semester 6 yang berjumlah 98 orang. Hasil penelitian menunjukkan bahwa separuh dari contoh memiliki tingkat keanekaragaman konsumsi pangan yang tergolong ke dalam kategori tinggi. Tingkat kecukupan energi, protein, lemak, besi, kasium, dan vitamin C contoh tergolong defisit berat, namun tingkat kecukupan karbohidrat dan vitamin A-nya tergolong sudah cukup. Status gizi contoh sebagian besar tergolong normal. Hasil uji hubungan menunjukkan adanya hubungan signifikan positif antara tingkat keanekaragaman konsumsi pangan dengan tingkat kecukupan gizi dan status gizi contoh.

Judul: Pengetahuan Gizi, Kebiasaan Makan, Konsumsi Minuman Manis, Tingkat Kecukupan Gizi, dan Status Gizi Mahasiswa IPB University.
Abstrak: Penelitian ini bertujuan untuk menganalisis pengetahuan gizi, kebiasaan makan, konsumsi minuman manis, dan tingkat kecukupan energi dan zat gizi dengan status gizi pada mahasiswa IPB University. Desain penelitian ini adalah cross sectional study dengan melibatkan 46 mahasiswa berstatus gizi normal dan 46 mahasiswa berstatus gizi gemuk/obesitas. Sebagian subjek memperoleh tingkat pengetahuan gizi rendah (50%), skor kebiasaan makan rendah (81,5%), asupan energi minuman manis sedang (45,7%), frekuensi konsumsi minuman manis sering (75%), dan tingkat kecukupan energi (76,1%), protein (68,5%), lemak (67,4%), dan karbohidrat (78,3%) kurang. Terdapat perbedaan yang signifikan antara kelompok status gizi normal dan gemuk pada variabel asupan energi minuman manis dan frekuensi konsumsi minuman manis (p<0,05). Uji korelasi menunjukkan terdapat hubungan yang signifikan antara frekuensi konsumsi minuman manis, tingkat kecukupan protein dan lemak dengan status gizi (p<0,05). Hasil uji regresi menunjukkan secara keseluruhan terdapat pengaruh antara frekuensi konsumsi minuman manis terhadap status gizi., This study aims to analyze the nutritional knowledge, eating habits, consumption of sweetened beverages, energy and nutrients adequacy level with the nutritional status of IPB University students. The design of this study was cross sectional study involved 46 students with normal nutritional status and 46 students with overweight/obese nutritional status. Most subject has low nutritional knowledge (50%), low eating habits’ score (81,5%), moderate energy intake of sweetened beverages (45,7%), high frequency of sweetened beverages consumption (75%), and low adequacy level of energy (76,1%), protein (68,5%), fat (67,4%) dan carbohydrate (78,3%). There was a significant difference of normal and overweight/obese students in energy intake of sweetened beverages and frequency of sweetened beverages consumption (p<0,05). There was a significant correlation between frequency of sweet beverages consumption, adequacy level of protein and fat with nutritional status (p<0,05). Regression test result showed over all there was an effect in frequency of sweetened beverages consumption to nutritional status.

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.
