Judul: Pengembangan Alat Ukur Pengetahuan, Sikap Dan Praktek Gizi Pada Remaja
Abstrak: Untuk menilai pengetahuan, sikap dan praktek gizi pada remaja diperlukan suatu alat ukur. Konsistensi pengukuran dan akurasi data yang dikumpulkan dalam suatu penelitian tergantung pada alat ukur (instrumen/kuesioner) yang digunakan. Suatu alat ukur yang standar harus memenuhi kriteria psikometrik yaitu validitas dan reliabilitas. Sampai saat ini, di Indonesia belum ada kajian ilmiah yang membahas alat ukur pengetahuan, sikap dan praktek gizi pada remaja yang memenuhi standar. Alat ukur yang digunakan untuk pengetahuan, sikap dan praktek gizi seadanya dan hanya terbatas digunakan untuk kalangan tertentu. Selain itu, alat ukur yang digunakan untuk kelompok sasaran yang sama bisa berbeda-beda dan sebaliknya alat ukur yang digunakan pada kelompok sasaran yang berbeda menggunakan alat ukur yang sama. Analisis pengetahuan, sikap dan praktek gizi pada remaja diperlukan sebagai dasar untuk melakukan upaya peningkatan perilaku gizi remaja. Tujuan penelitian ini adalah (1) merumuskan alat ukur pengetahuan, sikap dan praktek gizi pada remaja yang standar dan (2) menganalisis pengetahuan, sikap dan praktek gizi pada remaja.

Judul: Analisis Pengetahuan, Sikap, dan Praktik Gizi Remaja Putri SMP dan SMK di Kecamatan Ciampea, Bogor.
Abstrak: Tingkat pendidikan dapat menggambarkan kognitif dan pengetahuan yang dimiliki oleh seseorang. Tujuan penelitian ini adalah menganalisis perbedaan pengetahuan, sikap, dan praktik gizi remaja putri Sekolah Menengah Pertama (SMP) dan Sekolah Menengah Kejuruan (SMK) di Kecamatan Ciampea, Bogor. Desain penelitian adalah cross sectional melibatkan 387 subjek terdiri atas 176 subjek SMP dan 211 subjek SMK. Data pengetahuan, sikap, dan praktik gizi diperoleh melalui masing-masing 15 pertanyaan dengan menggunakan kuesioner, sementara data status gizi diperoleh melalui pengukuran antropometri. Pengetahuan (9.4 ± 1.6 vs 8.6 ± 1.5), sikap (12.5 ± 1.7 vs 12.0 ± 2.0), dan status gizi (-0.2 ± 1.1 vs -0.6 ± 1.4) pada subjek SMK secara signifikan lebih baik dibandingkan dengan subjek SMP, sementara praktik gizi (37.9 ± 5.9 vs 36.8 ± 5.8) pada subjek SMP cenderung lebih baik dibandingkan dengan subjek SMK.

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.
