Judul: Studi Perbandingan Metode Recall Konsumsi Pangan dan Recall Pengeluaran Pangan dengan Metode Penimbangan Makanan (Food Weighing)
Abstrak: Tujuan Penelitian ini yaitu: 1) membandingkan pengumpulan data konsumsi pangan keluarga melalui metode recall konsumsi pangan tujuh hari berturut-turut dan recd pengeluaran pangan mingguan dengan metode penimbangan makanan selama tujuh hari (sebagai standar) untu k melihat konsumsi bahan makanan; 2) membandingkan pengumpulan data konsumsi pangan keluarga melalui metode recall konsumsi pangan tujuh hari berturut-turut dan recall pengeluaran pangan mingguan dengan metode penimbangan makanan selarna tujuh hari (sebagai standar) untuk melihat konsumsi energi dan zat gizi lainnya clan 3) mengidentiftkasi ragam jumlah jenis pangan, ragam konsumsi antar waktu dan ragam konsumsi antar keluarga dengan menggunakan metode recall konsumsi pangan tujuh hari berturut-turut dan penirnbangan makanan selama tujuh hari. Data konsumsi pangan yang diperoleh dengan menggunakan metode recall tujuh hari bertunit-turut, recall pengeluaran pangan mingguan dan metode penimbangan makanan selama tujuh hari dikonversi ke dalam satuan konsumsi energi dan zat gizi Iainnya (protein, lemak, karbohidrat, kalsium, phospor, zat besi, vitamin A, vitamin B dan vitamin C) menggunakan Daftar Komposisi Bahan Makanan (DKBM).

Judul: Studi perbandingan metode pengumpulan data konsumsi pangan kelurga
Abstrak: Berbagai studi mengenai metode pengumpulan data konsumsi pangan telah dilakukan. Setiap metode mempunyai keuntungan dan kerugian. Penelitian ini bertujuan untuk membandingkan metode "recall" konsumsi pangan dua hari berturut-turut dengan metode "recall" pengeluaran pangan bulanan untuk melihat konsumsi energi dan protein keluarga. Data yang digunakan diperoleh dari Proyek "Food Security", Institut Pertanian Bogor di Desa Karang Menggah, Kecamatan Wonorejo, Kabupaten Pasuruan, Jawa Timur pada tahun 1987. Data yang dianalisis meliputi data identitas keluarga dan data konsumsi pangan keluarga yang dikumpul kan melalui dua metode "recall" selama tiga bulan mulai bulan Juli sampai bulan September 1987.

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.
