Judul: Pengembangan Media Edukasi Gizi Buku Harian Makanku serta Pengaruhnya terhadap Perilaku Makan Anak Sekolah Dasar
Abstrak: Masalah gizi ganda lebih sering ditemukan pada anak-anak usia 5 sampai 12 tahun. Anak sekolah dasar merupakan salah satu kelompok yang rawan mengalami masalah gizi ganda. Penelitian ini bertujuan untuk mengembangkan media pendidikan gizi Buku Harian Makanku, menganalisis tingkat penerimaan, dan pengaruhnya terhadap peningkatan pengetahuan, sikap, dan praktik terkait gizi seimbang anak sekolah dasar. Desain studi berupa quasy experimental study yang dimulai bulan Agustus hingga November 2018. Penarikan subjek dengan metode purposive dan melibatkan 68 siswa SD Negeri Gunung Batu 2 Bogor. Data karakteristik individu, tingkat penerimaan media, serta data pengetahuan, sikap, dan praktik terkait pedoman gizi seimbang diperoleh melalui kuesioner. Data frekuensi konsumsi makan subjek diperoleh melalui media Buku Harian Makanku (BHM). Hasil penelitian ini menunjukkan bahwa media BHM dapat diterima oleh subjek. Hasil penelitian ini juga menunjukkan bahwa pengetahuan dan sikap subjek yang diberikan media BHM maupun diberikan edukasi gizi disertai buku mengalami peningkatan. Sementara itu, praktik subjek terkait pedoman gizi seimbang pada kedua perlakuan tidak meningkat secara signifikan.

Judul: Keterkaitan antara Pemberian Media Pendidikan Gizi Menggunakan Buku Harian Makanku dengan Pengetahuan dan Sikap Gizi serta Praktik Makan Anak Sekolah Dasar
Abstrak: Buku Harian Makanku (BHM) merupakan media pendidikan gizi yang berisi catatan makanan subjek. Penelitian bertujuan untuk menganalisis hubungan pendidikan gizi menggunakan BHM dengan pengetahuan (PE) dan sikap (SI) gizi, serta praktik makan (PR) anak sekolah dasar. Penelitian berupa quasy experimental study terhadap 70 orang siswa beserta ibu, pada bulan Oktober-November 2019, di SDN 1 Gunung Batu. Intervensi BHM dilakukan setiap hari dan leaflet pedoman gizi seimbang (PGS) dilakukan sekali seminggu selama 30 hari. Data karakteristik, PE, SI, dan PR diperoleh melalui kuesioner. Data keragaman makan anak diperoleh melalui BHM. Hasil penelitian menunjukkan bahwa intervensi dapat meningkatkan PE dan SI gizi subjek, serta pengetahuan gizi ibu, meskipun peningkatannya tidak signifikan. Selain itu, pendidikan gizi juga belum berdampak pada perbaikan PR dan keragaman makan subjek. Tidak terdapat hubungan yang signifikan antara pengetahuan gizi ibu dengan PE, SI, dan PR pada subjek. Perlu pendidikan gizi secara berkelanjutan, terutama kepada Ibu. BHM dapat dijadikan instrumen untuk mengetahui kebiasaan makan anak.

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.
