Abstrak: Mediamassa sebagai saluran komunikasi massa memiliki beberapa fungsi dan peranan, salah satu peranan penting dari media massa adalah sebagai pemuas kebutuhan khalayak dalam memberikan informasi. Media cetak sebagai salah satu saluran dari komunikasi massa merupakan jenis media yang paling tua umurnya dibandingkan dengan jellis media massa lainnya, tetapi dengan sejumlah karakteristik dan keunikan yang dimilikinya maka media cetak masih digunakan oleh khalayaknya untuk memperoleh informasi lebih detail dan terperinci.

Judul: Pengaruh Motivasi dan Perilaku Pembaca Terhadap Keputusan Dosen IPB Dalam Membaca Media Online
Abstrak: Saat ini industri media cetak mengalami masalah serius. Perkembangan teknologi di bidang komunikasi dan informasi telah menyebabkan media online tumbuh dengan cepat menggantikan fungsi media cetak. Pertumbuhan media online mendorong industri media cetak mengubah produk mereka menjadi versi online, bahkan beberapa perusahaan berhenti cetak dan tidak berproduksi lagi. Penelitian ini bertujuan (1) menganalisis pengaruh motivasi pembaca terhadap keputusan membaca media online (2) menganalisis pengaruh motivasi pembaca terhadap perilaku membaca media cetak (3) menganalisis pengaruh motivasi pembaca terhadap perilaku membaca media online (4) menganalisis pengaruh perilaku membaca media cetak terhadap keputusan membaca media online (5) menganalisis pengaruh perilaku membaca media online terhadap keputusan membaca media online. Penelitian ini dilakukan di Institut Pertanian Bogor terhadap 92 dosen IPB sebagai responden penelitian. Teknik proportional stratified random sampling digunakan dalam penelitian ini. Structural Equation Model (SEM) berbasis Smart PLS versi 2.0 dengan 4 variabel laten yang terdiri dari motivasi pembaca, perilaku membaca media cetak, perilaku membaca media online dan keputusan membaca media online digunakan dalam penelitian ini untuk menganalisis data. Hasil penelitian menunjukkan bahwa (1) motivasi pembaca mempunyai pengaruh signifikan terhadap keputusan membaca media online (2) motivasi pembaca mempunyai pengaruh signifikan terhadap perilaku membaca media cetak (3) motivasi pembaca mempunyai pengaruh signifikan terhadap perilaku membaca media online (4) perilaku membaca media cetak tidak mempunyai pengaruh terhadap keputusan membaca media online (5) perilaku membaca media online tidak mempunyai pengaruh terhadap keputusan membaca media online.

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.
