Judul: Hubungan Praktik Pemberian ASI dan MP-ASI dengan Status Gizi pada Bayi Usia 6-11 bulan di Kelurahan Menteng Kota Bogor
Abstrak: Penelitian ini bertujuan menganalisis hubungan praktik pemberian ASI dan MP-ASI dengan status gizi bayi 6-11 bulan di Kelurahan Menteng, Kota Bogor. Desain penelitian adalah cross sectional study dengan consecutive sampling yang melibatkan subjek 53 bayi usia 6-11 bulan. Praktik pemberian ASI dan MP-ASI diukur dengan menggunakan metode Infant and Child Feeding Index (ICFI). Status gizi diukur dengan z-score. Praktik pemberian ASI dan MP-ASI mayoritas subjek kelompok usia 6-8 bulan berada pada kategori sedang, sedangkan mayoritas subjek kelompok usia 9-11 bulan berada pada kategori tinggi. Sebanyak 1.9% subjek tergolong stunting dan 5.7% subjek tergolong overweight. Hasil uji Spearman menunjukkan tidak terdapat hubungan signifikan antara praktik pemberian ASI dan MP-ASI dengan status gizi subjek (p>0.05).

Judul: Hubungan Praktik Pemberian ASI dan MP-ASI dengan Morbiditas dan Status Gizi Baduta Usia 6-24 Bulan di Kota Bogor
Abstrak: Praktik pemberian ASI dan MP-ASI dalam periode 1000 Hari Pertama Kehidupan merupakan salah satu faktor penting yang dapat menentukan status gizi anak di usia mendatang. Penelitian ini bertujuan menganalisis hubungan praktik pemberian ASI dan MP-ASI dengan morbiditas dan status gizi baduta. Desain penelitian ini adalah cross sectional study dengan consecutive sampling yang melibatkan 42 subjek. Praktik pemberian ASI dan MP-ASI diukur dengan metode wawancara dan instrumen berupa Infant and Child Feeding Index (ICFI). Status gizi diukur dengan z-score. Praktik pemberian ASI dan MP-ASI mayoritas subjek kelompok usia 6-8 dan 9-11 bulan berada pada kategori baik, sedangkan mayoritas subjek kelompok usia 12-24 bulan berada pada kategori cukup baik. Kejadian morbiditas subjek dalam satu bulan terakhir tergolong rendah. Sebanyak 23.8% subjek tergolong stunting dan 7.1% tergolong overweight. Tidak terdapat hubungan signifikan antara praktik pemberian ASI dan MP-ASI dengan morbiditas maupun status gizi subjek (p>0.05). Terdapat hubungan positif yang signifikan antara berat badan lahir subjek dengan status gizi indeks BB/U (p=0.012, r=0.383) yang bermakna bahwa subjek dengan berat badan lahir rendah berpeluang lebih besar untuk mengalami gizi kurang.

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.
