Judul: Analisis penerimaan, pengetahuan, dan lama penggunaan media cakram gizi remaja pada siswa SMP dan SMA di Kota Bogor.
Abstrak: Remaja dengan status gizi normal merupakan investasi yang menentukan kualitas sumber daya manusia di masa yang akan datang. Media edukasi gizi sangat diperlukan di sekolah-sekolah agar remaja lebih peduli terhadap status gizi mereka masing-masing. Cakram gizi remaja yang diproduksi oleh PERGIZI PANGAN ialah sebuah media edukasi untuk mengetahui status gizi seseorang dengan cepat, tepat, dan mudah. Penelitian ini bertujuan untuk menganalisis tingkat penerimaan, pengetahuan, dan lama penggunaan cakram gizi pada remaja. Desain studi berupa cross-sectional yang dimulai sejak bulan Mei hingga bulan Agustus 2018. Penarikan subjek dengan metode purposive ini melibatkan 82 siswa dari SMPN 5 Bogor dan 85 siswa dari SMAN 3 Bogor. Data primer meliputi karakteristik subjek dan keluarga, tingkat penerimaan, pengetahuan, yang dikumpulkan melalui hasil dari penyebaran kuesioner dan lama penggunaan cakram diukur dengan stopwatch. Data sekunder meliputi gambaran sekolah serta adanya alat edukasi pemantauan status gizi, yang dikumpulkan melalui proses wawancara. Menurut pendapat ahli, cakram bermanfaat sebagai tahap awal dalam pemantauan status gizi remaja yang cepat, tepat, dan mudah. Namun, masih diperlukan penambahan sejumlah informasi gizi pada cakram yang telah beredar. Secara keseluruhan, baik siswa SMP dan SMA tertarik dan dapat menerima visualisasi, desain dan layout, isi, serta informasi keseluruhan cakram. Sebagian besar siswa SMA (61.2%) maupun siswa SMP (52.4%) tergolong sangat baik dalam tingkatan pengetahuan mengenai isi cakram. Rata-rata siswa SMP menghabiskan waktu 31.6 ± 15.6 detik dan siswa SMA menghabiskan waktu 27.8 ± 9.2 detik untuk menggunakan kedua sisi cakram cakram dengan efektif. Terdapat perbedaan nyata (p<0.05) antar sekolah mengenai tingkat pengetahuan cakram dan lama penggunaannya. Tidak terdapat perbedaan nyata (p>0.05) mengenai penerimaan secara keseluruhan cakram gizi remaja pada siswa SMP dan SMA.

Judul: Hubungan Pengetahuan, Sikap, dan Praktik Gizi dengan Keragaman Konsumsi Pangan Remaja di Kecamatan Ciampea, Bogor
Abstrak: Pengetahuan, sikap, dan praktik gizi merupakan faktor tercapainya keseimbangan zat gizi remaja. Penelitian ini bertujuan untuk menganalisis hubungan pengetahuan, sikap, dan praktik gizi dengan keragaman konsumsi pangan remaja di Kecamatan Ciampea, Bogor. Penelitian berdesain cross-sectional ini menggunakan data sekunder penelitian lain yang dilakukan pada bulan Oktober 2017 – Febuari 2018 terhadap 262 siswi SMP dan SMK. Variabel yang diteliti meliputi karakteristik remaja, pengetahuan gizi, sikap gizi, praktik gizi, asupan zat gizi, status gizi, dan keragaman konsumsi pangan remaja. Hasil penellitian ini menunjukkan bahwa sebagian besar remaja putri memiliki pengetahuan gizi sedang, sikap gizi baik, dan praktik gizi sedang. Rata-rata skor keragaman konsumsi pangan (IDDS) remaja putri tergolong tinggi (≥6 jenis kelompok pangan). Terdapat hubungan positif signifikan antara usia dan uang saku remaja putri dengan pengetahuan dan sikap gizi (p<0,05). Karakteristik remaja putri memiliki hubungan positif signifikan dengan keragaman konsumsi pangan (p<0,05). Pendidikan gizi mendorong alokasi uang saku yang sesuai dengan prinsip gizi seimbang penting untuk dilakukan., Nutritional knowledge, attitude, and practice are important factors for balanced nutrition for adolescents. This research aimed to analyze relationship between nutritional knowledge, attitude, practice, and dietary diversity of adolescents in Ciampea district, Bogor. This cross-sectional study used secondary data of a study conducted in October 2017 – February 2018 to 262 junior and vocational high school students. Variables included were individual characteristics, nutritional knowledge, attitude, and practice, nutrient intake, nutritional status, and dietary diversity. Results showed that majority of adolescent girls had fair nutritional knowledge, good nutritional attitude, and fair nutritional practice. Average individual dietary diversity score (IDDS) of adolescents was high (≥6 food groups). There were positive significant associations (p<0.05) on age and school allowance with nutritional knowledge and attitude. These individual characteristics were also associated with dietary diversity of adolescents (p<0.05). Nutrition education encouraging proper allocation of school allowance in line with balanced nutrition guidelines is important.

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.
