Judul: Studi perbandingan beberapa metode estimasi umur dalam pengukuran status gizi anak balita secara antropometri
Abstrak: Penelitian ini bertujuan untuk membandingkan beberapa metode estimasi umur dalam pengukuran status gizi anak balita dengan menggunakan indikator antropometri yang tergantung pada umur, khususnya berat badan menurut umur dan tinggi badan menurut umur (BB/U dan TB/U). Selain itu juga untuk mengetahui faktor koreksi umur dari metode Ibu, kartu keluarga (KK), dan kartu menuju sehat (KMS) terhadap metode Lacak; prevalensi status gizi berdasarkan setiap metode estimasi umur, dan untuk mengetahui hubungan antara faktor umur ibu, jumlah anak yang pernah dilahirkan ibu, lama pendidikan formal ibu, dan umur anak balita dengan ketepatan informasi ibu tentang umur anak balitanya. Contoh dipilih dari populasi anak balita yang ada di Kelurahan Tegallega, Kecamatan Bogor Timur, Kotamadia Bogor dengan kriteria Memiliki kartu menuju sehat (KMS), terdaftar di Pos Pelayanan Terpadu (posyandu) setempat, dan terdaftar dalam kartu keluarga (KK) 1989. Berdasarkan kriteria itu terpilih 128 anak balita dari 122 keluarga dan semuanya dijadikan contoh.

Judul: Penggunaan standar antropometri lokal dan internasional untuk menilai status gizi anak usia 12 sampai 60 bulan di kecamatan Kebayoran Baru, Jakarta Selatan
Abstrak: Penelitian ini bertujuan untuk mempelajari pola pertumbuhan anak usia 12 sampai 60 bulan dengan membandingkan antar tiga standar antropometri yaitu standar Lokal dan standar Internasional (Harvard dan NCHS) serta mempelajari perbedaan penetapan status gizi anak usia 12 sampai 60 bulan antar ketiga standar tersebut menggunakan tiga indeks yaitu BB/U (berat menurut umur), BB/TB (berat menurut tinggi) dan TB/U (tinggi menurut umur). Penelitian ini dilakukan di Kecamatan Kebayoran Baru, Jakarta Selatan yang dipilih secara purposif dan meliputi delapan kelurahan. Penelitian dilaksanakan sejak akhir bulan Maret sampai bulan Juli 1989 Sebagai contoh dalam penelitian ini adalah anak usia 12 sampai 60 bulan yang tidak sakit yang ditentukan dengan cara acak stratifikasi berdasarkan umur dalam satuan bulan (49 strata umur). Jumlah contoh pada setiap strata umur antara 30 sampai 50 anak, sehingga diperoleh contoh sebanyak 2047 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.
