Judul: Interaksi Sosial, Strategi Koping, dan Kesejahteraan Subjektif Lansia di Masa Pensiun
Abstrak: Penelitian ini bertujuan untuk menganalisispengaruh interaksi sosial, strategi koping, dan kesejahteraan subjektiflansia di masa pensiun. Desain penelitian yang digunakan adalah cross-sectional study. Penelitian dilakukan di Kelurahan Cilendek Barat, Kecamatan Bogor Barat. Jumlah contoh dalam penelitian ini berjumlah 60 orang lansia. Hasil penelitian menunjukkan tidak terdapat perbedaan nyata skor pencapaian interaksi sosial, strategi koping, dan kesejahteraan subjektif pada lansia laki-laki dan perempuan. Usia dan lama pensiun berhubungan negatif dengan interaksi sosial. Usia, lama pensiun, dan jumlah anak berhubungan positif dengan strategi koping. Terdapat hubungan dan pengaruh positif signifikan interaksi sosial terhadap kesejahteraan subjektif.

Judul: Pengaruh Dukungan Sosial dan Strategi Koping terhadap Kualitas Hidup Lansia
Abstrak: Saat ini Indonesia sedang memasuki tahap aging population karena persentase penduduk lanjut usia telah melebihi angka 10 persen. Kondisi kesehatan fisik yang terus menurun seiring bertambahnya waktu dapat mempengaruhi kualitas hidup, terutama pada kelompok lansia. Adanya permasalahan fisik serta gangguan psikologis membuat lansia semakin tergantung pada bantuan dan perawatan orang lain. Peran lingkungan sekitar seperti dukungan keluarga dan teman cukup penting dalam mencapai tugas-tugas perkembangan individu di setiap tahapannya, terutama pada lansia. Penelitian ini bertujuan untuk menganalisis pengaruh dukungan sosial dan strategi koping terhadap kualitas hidup lansia. Contoh dalam penelitian ini berjumlah 60 orang dengan usia lebih dari sama dengan 60 tahun keatas yang masih memiliki pasangan. Penelitian berlokasi di wilayah Kabupaten Kebumen, Jawa Tengah dengan menggunakan desain penelitian cross-sectional study. Pengambilan contoh dilakukan melalui pengisian kuesioner dengan wawancara langsung. Hasil penelitian menunjukkan lama pendidikan, pendapatan per kapita, dukungan sosial, dan strategi koping berhubungan positif sangat signifikan dengan kualitas hidup lansia. Hasil uji regresi menunjukkan bahwa pendapatan per kapita dan dukungan sosial berpengaruh positif signifikan terhadap kualitas hidup lansia.

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.
