Judul: Analisis Keputusan Bisnis dalam Pembelian Produk Makanan Halal di Kota Ho Chi Minh, Vietnam
Abstrak: Populasi muslim yang meningkat setiap tahunnya di Vietnam berdampak pada peningkatan permintaan produk halal. Produk makanan yang berada di pasar saat ini sangat beragam dan bisa jadi mengandung bahan yang tidak boleh dimakan oleh umat muslim. Penelitian ini bertujuan untuk menganalisis karakteristik konsumen muslim Vietnam di kota Ho Chi Minh, menganalisis pengaruh theory of planned behavior dan daya saing produk terhadap keputusan bisnis dalam pembelian produk makanan halal. Sampel dalam penelitian ini berjumlah 66 responden yang dipilih dengan teknik convenience sampling. Analisis faktor dilakukan dengan menggunakan metode SEM-PLS, sedangkan karakteristik konsumen muslim Vietnam dianalisis dengan menggunakan analisis deskriptif. Hasil penelitian menunjukkan bahwa theory of planned behavior dan daya saing produk berpengaruh signifikan dan memengaruhi pengambilan keputusan pembelian. Variabel dengan hasil pengaruh terbesar adalah sikap dan variasi produk.

Judul: Analisis Faktor-Faktor dalam Keputusan Pembelian Terencana Produk Makanan Halal di Daerah Penyangga Ibukota
Abstrak: Makanan adalah kebutuhan setiap manusia. Namun bagi setiap muslim, makanan yang dikonsumsi harus terjamin kehalalannya Namun diketahui bahwa sebagian besar produk yang beredar di Indonesia belum tersertifikasi halal. Berdasarkan dari teori perilaku terencana (Ajzen 2011), hal tersebut diasumsikan akan mempengaruhi keputusan konsumen dalam membeli produk makanan. Selain itu faktor-faktor lingkungan makro menurut Kotler dan Keller (2016) akan mempengaruhi keputusan pembelian konsumen sehingga akan berdampak pada keuntungan yang didapatkan perusahaan. Penelitian ini akan mengkombinasikan teori perilaku keputusan dengan faktor-faktor lingkungan eksternal dalam mempengaruhi minat beli produk makanan halal dan pengaruh tidak langsung terhadap keputusan pembelian produk makanan halal oleh masyarakat di daerah penyangga ibukota (kota dan kabupaten Bogor, kota dan kabupaten Bekasi, serta kota Depok) dengan variabel minat beli sebagai vaiabel intervensi. Hasil analisis SEM-PLS menunjukkan bahwa variabel sikap, norma subjektif, kendali perilaku, ekonomi, dan sosial-budaya berpengaruh secara tidak langsung terhadap keputusan pembelian konsumen.

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.
