Judul: Perilaku Gizi dan Kehadiran di Posbindu Lansia serta Kaitannya dengan Hipertensi.
Abstrak: Meningkatnya Umur Harapan Hidup secara otomatis akan menambah jumlah lanjut usia yang akan berdampak pada pergeseran pola penyakit di masyarakat salah satunya adalah hipertensi. Tujuan penelitian ini adalah menganalisis perilaku gizi dan kehadiran di posbindu lansia dalam kaitannya dengan hipertensi. Desain penelitian adalah cross-sectional study, melibatkan 100 subjek. Data karakteristik contoh, perilaku gizi, asupan garam dan lemak serta kehadiran ke posbindu lansia dikumpulkan melalui wawancara menggunakan kuesioner. Data kebiasaan makan menggunakan metode FFQ yang di konversi dalam satuan kali/minggu. Tempat dan subjek penelitian dipilih secara purposive. Variabel yang diteliti adalah karakteristik contoh, perilaku gizi, status gizi, kehadiran ke posbindu lansia dan tekanan darah. Hasil uji korelasi Rank Spearman menunjukkan hubungan yang signifikan antara praktik gizi, asupan garam dan minyak, status gizi dengan tekanan darah dan jenis kelamin dan umur dengan kehadiran di posbindu lansia (p< 0.05). Tidak ada hubungan yang signifikan antara kehadiran di posbindu lansia dengan pendidikan, status bekerja, pengetahuan dan sikap gizi (p> 0.05).

Judul: Gaya Hidup, Konsumsi Pangan, dan Hubungannya dengan Tekanan Darah pada Lansia Anggota Posbindu.
Abstrak: Penelitian bertujuan untuk mengetahui hubungan gaya hidup dan konsumsi pangan dengan tekanan darah pada lansia anggota posbindu. Desain penelitian adalah cross-sectional dengan jumlah subjek 8 orang laki-laki dan 31 orang perempuan dari Posbindu Al-Wusto, Kabupaten Bogor. Data gaya hidup berupa kebiasaan merokok, minum kopi, dan berolahraga diperoleh menggunakan kuesioner. Data konsumsi pangan berupa pangan pencegah dan pemicu hipertensi diperoleh menggunakan Food Frequency Questionnaire (FFQ). Data tekanan darah diperoleh dengan pengukuran langsung menggunakan tensimeter digital. Sebagian besar subjek (64.1%) mempunyai hipertensi, sebanyak 28.2% subjek memiliki hipertensi I dan 35.9% subjek memiliki hipertensi II. Tidak terdapat hubungan yang signifikan antara gaya hidup dengan tekanan darah (p>0.05). Terdapat hubungan signifikan negatif antara pangan pencegah (brokoli dan biji bunga matahari) dan pangan pemicu (crackers dan ikan asin) dengan tekanan darah sistol (p<0.05). Terdapat hubungan signifikan positif antara pangan pemicu (ikan pindang) dengan tekanan darah sistol (p<0.05).

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.
