Judul: Hubungan Tingkat Partisipasi dengan Pengatahuan dan Status Gizi Lansia di Posbindu Kelurahan Pasir Kuda
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan tingkat partisipasi dengan pengetahuan dan status gizi lansia di Posbindu Kelurahan Pasir Kuda. Desain penelitian yang digunakan adalah cross-sectional. Contoh dalam penelitian ini adalah 96 orang lansia yang berusia ≥55 tahun. Tempat penelitian dipilih secara purposive dengan pengambilan contoh secara accidental sampling. Penelitian dilaksanakan pada bulan Maret–Mei 2015. Hasil penelitian menunjukkan bahwa sebagian besar contoh memiliki tingkat partisipasi (58.3%) dan pengetahuan tentang gizi dan Posbindu (66.7%) kategori sedang. Status gizi contoh 35.4% tergolong obese-I dan 9.4% tergolong underweight. Berdasarkan uji korelasi Pearson terdapat hubungan yang signifikan antara tingkat partisipasi dengan pengetahuan tentang gizi dan Posbindu (p<0.01) serta status gizi contoh (p<0.1).

Judul: Analisis Perbedaan Pengetahuan Gizi, Status Gizi, Tekanan Darah dan Aktivitas Fisik pada Lansia Peserta dan Bukan Peserta Posbindu
Abstrak: Angka Harapan Hidup Sehat (AHHS) Indonesia pada tahun 2016 adalah 12.7 tahun yang menandakan bahwa lansia Indonesia dapat menjalani hidup mereka dalam kondisi sehat sampai usia 72-73 tahun. Penyakit terbanyak pada lansia berdasarkan Riset Kesehatan Dasar tahun 2013 yaitu hipertensi yaitu sebanyak 57,6% (Depkes 2018). Tujuan penelitian ini adalah untuk melihat perbedaan pengetahuan gizi, status gizi, tekanan darah dan aktivitas fisik lansia peserta posbindu dan lansia bukan peserta posbindu. Desain penelitian adalah cross sectional study, melibatkan 100 responden. Data karateristik responden, persepsi posbindu, pengetahuan gizi, aktivitas fisik dan konsumsi pangan dikumpulkan melalui wawancara menggunakan kuesioner. Data konsumsi pangan menggunakan metode SQ-FFQ. Tempat dan responden penelitian dipilih secara purposive. Variabel yang diteliti adalah karakteristik responden, pengetahuan gizi, status gizi, tekanan darah, aktivitas fisik dan tingkat kecukupan gizi. Tidak terdapat perbedaan yang signifikan pada pengetahuan gizi (p=0,125), status gizi (p=0,231), tekanan darah sistolik (p=0,459), tekanan darah diastolik (p=0,568) pada kedua kelompok responden. Terdapat perbedaan yang signifikan (p<0,05) pada tingkat kecukupan energi, protein, lemak dan karbohidrat pada kedua kelompok responden.

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.
