Judul: Efektivitas LINE sebagai Media Promosi Produk Olahan Pertanian (Kasus: Ayam Geprek Pejuang Bogor Barat).
Abstrak: Pertanian adalah aspek penting dalam pemenuhan kebutuhan pangan, salah satunya pada subsektor peternakan. Produk pertanian memiliki karakteristik yang mudah rusak, volume besar, dan mengambil ruang besar menuntut untuk mengolah produk pertanian tersebut. Seiring dengan perkembangan teknologi, internet dimanfaatkan untuk memasarkan suatu produk melalui sosial media. Penelitian ini bertujuan untuk menganalisis hubungan keterdedahan dalam mengakses media sosial dengan efektivitas media komunikasi. Penelitian menggunakan teknik sampel aksidental dengan menggunakan uji statistik Chi-square dan Rank Spearman. Hasil penelitian menunjukkan bahwa LINE dinilai efektif sebagai media promosi produk olahan pertanian. Berdasarkan uji statistik, karakterisrik responden dan beberapa indikator pada keterdedahan media komunikasi tidak memiliki hubungan yang signifikan dengan keterdedahan terhadap media sosial. Hasil penelitian juga menunjukkan bahwa keterdedahan terhadap media sosial tidak memiliki hubungan yang signifikan dengan efektivitas media komunikasi.

Judul: Efektivitas Instagram sebagai Media Promosi Produk Olahan Pertanian Serambi Botani.
Abstrak: Produk olahan pertanian yang sebagian besar beroperasi di pedesaan dan berupa sektor usaha kecil biasanya membuat promosi melalui media konvensional seperti brosur, poster, booklet dan lainnya sudah tidak efektif. Penjualan secara konvensional mulai banyak ditinggalkan karena munculnya inovasi dalam teknologi informasi dan komunikasi dimana pembelian barang atau jasa dapat dilakukan melalui internet salah satunya media sosial instagram. Tujuan penelitian adalah menghasilkan analisis efektivitas instagram sebagai media promosi, menganalisis hubungan karakteristik followers dengan tingkat keterdedahan media sosial serta menganalisis hubungan tingkat keterdedahan media sosial dengan efektivitas instagram sebagai media promosi. Penelitian menggunakan metode survei dengan data kuantitatif berupa kuesioner online yang didukung oleh data kualitatif berupa wawancara mendalam dengan satu orang admin instagram Serambi Botani sebagai informan. Jumlah responden dalam penelitian adalah 40 orang. Hasil penelitian menunjukkan bahwa instagram efektif dalam meningkatkan pengetahuan (aspek kognitif) responden terkait produk olahan pertanian Serambi Botani.

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.
