Judul: Alokasi Uang Saku, Food Coping Strategy, dan Tingkat Kecukupan Gizi Mahasiswa Penerima Bidikmisi Institut Pertanian Bogor
Abstrak: Tujuan penelitian ini adalah menganalisis alokasi uang saku, food coping strategy, dan tingkat kecukupan gizi mahasiswa penerima bidikmisi IPB. Penelitian dilakukan dengan desain cross sectional study, pada bulan Maret-Mei 2016. Pemilihan contoh penelitian secara acak sederhana dengan jumlah contoh sebanyak 95 mahasiswa penerima bidikmisi yang tinggal di asrama PPKU IPB, terdiri dari 30 laki-laki dan 65 perempuan dengan usia 17-20 tahun. Hasil penelitian menunjukkan bahwa pengeluaran pangan sebesar 71.2%. Sebagian besar contoh memiliki tingkat food coping strategy kategori rendah dan sedang dengan rata-rata 7.1 ± 5.4, tingkat kecukupan energi dan protein kategori defisit berat, tingkat kecukupan vitamin A dan zat besi tergolong kurang, dan status gizi kategori normal. Hasil uji hubungan menunjukkan bahwa tidak terdapat hubungan signifikan (p>0.05) antara uang saku dengan pengeluaran pangan dan non pangan, pengeluaran pangan dan non pangan dengan tingkat food coping strategy, serta antara total pengeluaran pangan dan tingkat food coping strategy dengan tingkat kecukupan gizi. Hasil lain menunjukkan bahwa terdapat hubungan signifikan (p<0.05) antara beberapa kelompok pengeluaran pangan dengan tingkat kecukupan gizi, diantaranya pangan nabati, sayuran, buah-buahan, dan minuman.

Judul: Food coping strategy dan pola konsumsi pangan mahasiswa penerima dan non penerima beasiswa Bidikmisi Institut Pertanian Bogor
Abstrak: Tujuan utama penelitian ini adalah untuk menganalisis food coping strategy dan pola konsumsi pangan pada mahasiswa penerima dan non penerima beasiswa bidikmisi Institut Pertanian Bogor. Desain penelitian ini adalah cross sectional study dengan 72 contoh dari penerima dan non penerima beasiswa bidikmisi Institut Pertanian Bogor, yang dilaksanakan pada bulan April-Mei 2018. Sebagian besar contoh memiliki tingkat food coping strategy sedang pada mahasiswa bidikmisi (50%) maupun non bidikmisi (69.4%). Sebagian besar contoh memiliki tingkat kecukupan energi dan protein yang termasuk dalam kategori defisit berat baik pada bidikmisi maupun non bidikmisi. Hasil uji hubungan menunjukkan pada contoh bidikmisi dan non bidikmisi tidak terdapat hubungan signifikan antara pengeluaran pangan dan non pangan dengan food coping strategy (p=0.632 dan p=0.250), pengeluaran pangan dengan tingkat kecukupan energi (p=0.645 dan p=0.635) dan protein (p=0.487 dan p=0.474), dan food coping strategy dengan tingkat kecukupan energi (p=0.402 dan p=0.081) dan protein (p=0.533 dan p=0.371).

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.
