Judul: Breakfast Quality and Dietary Quality in Two High School Adolescents in Bogor City.
Abstrak: Tujuan penelitian ini adalah menilai kualitas sarapan dan kualitas konsumsi pangan serta hubungan keduanya pada remaja sekolah menengah atas di Kota Bogor. Desain penelitian ini adalah cross sectional study dengan responden 220 siswa dan siswi di dua SMA negeri dan swasta di Kota Bogor. Data konsumsi sarapan dan konsumsi pangan sehari diperoleh melalui food recall 1x24 jam. Kualitas sarapan dinilai dengan lima komponen berdasarkan Pedoman Gizi Seimbang yaitu memenuhi 15-30% kebutuhan energi sehari, memiliki indeks mutu gizi (IMG) zat gizi makro dan zat gzi mikro ≥15%, menu sarapan terdiri dari pangan sumber karbohidrat dan protein, sayur/buah dan minuman serta porsi sarapan memenuhi 25-30% total porsi sehari. Sebagian besar subjek tidak memenuhi kriteria tersebut sehingga 88.2% subjek memiliki kualitas sarapan kurang. Kualitas konsumsi pangan dinilai dengan Healthy Eating Index. Sebanyak 54.5% subjek memiliki kualitas konsumsi pangan dengan kategori kurang. Skor terendah ditemukan pada komponen konsumsi sayuran, konsumsi buah, konsumsi lauk nabati, asupan lemak total, dan asupan natrium. Tidak terdapat hubungan antara kualitas sarapan dan kualitas konsumsi pangan (p>0.05). Laki-laki memiliki skor sarapan berkualitas yang lebih tinggi dibandingkan perempuan (p<0.05).Subjek dengan pendapatan orangtua yang lebih rendah dan tinggal dengan orangtua memiliki skor total HEI yang lebih tinggi dibandingkan dengan subjek dengan pendapatan orangtua yang lebih tinggi dan tidak tinggal bersama dengan orangtua.

Judul: Kebiasaan Sarapan, Konsumsi Buah dan Sayur, dan Status Gizi Siswa Sekolah Menengah Pertama di Bogor
Abstrak: Fruits and vegetables are very important for consumption, especially for school-age children and adolescents. The purpose of this study were to analyze breakfast habits, fruits and vegetables consumption, and students’s nutritional status of junior high school in Bogor. The design of this study was cross-sectional with purposive sampling technique as much as 50 students in SMP Negeri 8 Bogor. Fruits and vegetables that consumed by students was included low as category. The result showed there was male students consumed breakfast more frequent than female students. Students’s nutritional status were categorized as normal. Correlation test showed there were no significant relationship (p>0.05) between individual and family characteristic, except households income with breakfast habits. There were no significant relationship (p>0.05) between individual and family characteristic, availability of fruits and vegetables at home, and parental habits of fruits and vegetables consumption, except households income with students of fruits consumption. Breakfast habits and fruits and vegetables consumption there were no significantly associated (p>0.05) with students’s 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.
