Judul: Hubungan Sarapan dengan Asupan Jajanan Siswa Peserta dan Bukan Peserta PROGAS di Kabupaten Cianjur
Abstrak: Tujuan penelitian ini adalah menganalisis pengetahuan gizi dan asupan sarapan serta jajanan siswa sekolah dasar peserta (SDN Pamoyanan) dan bukan peserta (SDN Ciwalen Peuntas) PROGAS di Kabupaten Cianjur. Desain penelitian yang digunakan adalah cross-sectional study dengan melibatkan 67 subjek. Penelitian dilaksanakan bulan November 2018 hingga Juli 2019. Pengumpulan data dilakukan dengan menggunakan kuesioner untuk karakteristik subjek, keluarga dan pengetahuan, food recall 2x24 jam untuk konsumsi pangan, dan Food Frequency Questionnaire (FFQ) untuk frekuensi konsumsi jajanan. Pengetahuan gizi subjek dari dua sekolah termasuk dalam kategori kurang (<60%). Kontribusi rata-rata asupan energi dan zat gizi sarapan dari dua kelompok sudah mencapai 25% total asupan harian. Rata-rata asupan energi jajanan pada subjek bukan peserta PROGAS lebih tinggi. Tidak terdapat hubungan signifikan antara karakteristik subjek dan keluarga, serta pengetahuan gizi dengan asupan sarapan (p>0.05). Terdapat hubungan signifikan antara pekerjaan ayah dan pengetahuan gizi dengan asupan jajanan, serta asupan karbohidrat sarapan dengan asupan lemak jajanan (p<0.05).

Judul: Hubungan Kebiasaan Sarapan dan Kebiasaan Jajandengan Status Gizi Siswa Sekolah Dasar di Kabupaten Sukabumi.
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan kebiasaan sarapan dan jajan dengan status gizi siswa sekolah dasar. Penelitian inimenggunakan desain cross sectional dengan melibatkan 105contoh. Dilaksanakan pada bulan April sampai Mei 2017. Contoh adalah siswa kelas 5 dari SDN Sukalarang, Sukabumi. Pengumpulan data karakteristik contoh dansosial ekonomi keluarga dilakukan dengan cara pengisiankuesioner; asupanharian, sarapan,dan jajanan diperoleh dengan Food Recall 24 jam selama 2 kali; jenis jajanan diperoleh melalui Semi Quantitative Food Frequency Questionnaire; status gizi ditentukan berdasarkan IMT/U. Hasil penelitian menunjukkan bahwa frekuensi sarapan contoh tergolong teratur. Jenis sarapan yang biasa dikonsumsi adalah makanan pokok dan lauk hewani. Jajanan yang paling sering dikonsumsi adalah camilan dan minuman. Terdapat hubungan positif signifikan (p<0.05) antara pendapatan keluarga dengan asupan energi dan karbohidrat sarapan; serta asupan protein jajanan. Terdapat hubungan negatif signifikan (p<0.05) antara kontribusi energi dan karbohidrat sarapan dengan asupan energi dan karbohidrat jajanan,dan hubungan negatif signifikan antara asupan lemak jajanan dengan status gizi (p<0.05).

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.
