Judul: Determinan Pembelian Makanan Tanpa Label Halal Melalui Layanan Online Food Delivery pada Muslim Generasi Z
Abstrak: Manusia memiliki kebutuhan dasar, salah satunya adalah makanan. Bagi umat muslim mengonsumsi makanan halal dan baik merupakan kewajiban, namun tidak semua makanan yang dijual telah berlabel halal. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian konsumen muslim generasi Z di Jawa Barat terhadap makanan tanpa label halal melalui online food delivery. Sampel dalam penelitian ini berjumlah 100 responden yang mewakili muslim generasi Z Jawa Barat. Analisis yang dilakukan adalah analisis deskriptif dan SEM-PLS. Hasil penelitian menunjukkan bahwa pengetahuan produk halal tidak berpengaruh signifikan terhadap sikap. Review konsumen memiliki pengaruh signifikan terhadap norma subjektif. Harga dan pendapatan berpengaruh signifikan terhadap persepsi kontrol perilaku, akan tetapi kualitas produk tidak berpengaruh signifikan terhadap persepsi kontrol perilaku. Niat pembelian dipengaruhi secara signifikan oleh persepsi kontrol perilaku, sedangkan sikap dan norma subjektif tidak berpengaruh signifikan terhadap niat pembelian. Persepsi kontrol perilaku, promosi, dan niat pembelian berpengaruh signifikan terhadap keputusan pembelian makanan tanpa label halal.

Judul: Analysis the Influence of Attitudes, Subjective Norms, Behavioral Control, and Product Attributes on the Z Generation’s Decision to Purchase Halal Labeled Local Cosmetics
Abstrak: Halal merupakan gaya hidup seorang Muslim. Generasi Z adalah generasi yang melek teknologi namun memiliki value tersendiri dalam kehidupan yang terkadang belum sesuai dengan nilai-nilai Islam, salah satuya terkait penggunaan kosmetik halal. Penelitian ini bertujuan menganalisis pengaruh dari sikap, norma subjektif, kontrol perilaku, dan atribut produk terhadap keputusan pembelian kosmetik lokal berlabel halal yang dilakukan oleh Generasi Z dan juga mengidentifikasi karakteristik Generasi Z yang membeli kosmetik lokal berlabel halal. Penelitian ini menggunakan metode analisis deskriptif dan SEM-PLS. Hasil penelitian menunjukkan bahwa responden didominasi oleh perempuan dan paling banyak berumur 20-24 tahun. Seluruh hipotesis dalam penelitian ini berpengaruh positif dan signifikan, kecuali hipotesis kontrol perilaku berpengaruh langsung terhadap keputusan pembelian.

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.
