Judul: Analisis Faktor-Faktor Pengambilan Keputusan Pembelian Kosmetik Berlabel Halal di Kota Bogor
Abstrak: Seiring dengan meningkatnya pertumbuhan industri kosmetik di Indonesia, kesadaran konsumen akan jaminan produk kosmetik yang halal juga meningkat. Fenomena tersebut menyebabkan pembelian kosmetik halal di Indonesia juga meningkat. Tujuan diadakannya penelitian ini adalah untuk mengidentifikasi karakteristik responden, menganalisis proses keputusan pembelian, dan menganalisis faktor-faktor keputusan pembelian produk kosmetik berlabel halal di Kota Bogor. Metode penarikan sampel yang digunakan adalah non probability sampling dengan teknik snowball sampling. Analisis dilakukan dengan analisis deskriptif, analisis faktor, analisis crosstab, dan Net Promoter Score (NPS). Berdasarkan hasil penelitian didapatkan tiga kelompok faktor baru yang membentuk keputusan pembelian kosmetik berlabel halal yaitu faktor individu, konsep diri dan sosial-budaya .Sebanyak 37% responden cenderung merekomendasikan produk kosmetik yang digunakannya kepada orang lain.

Judul: Faktor-Faktor yang Memengaruhi Minat Beli Kosmetik Halal di Kabupaten Bogor
Abstrak: Muslim diwajibkan untuk mengonsumsi produk halal. Salah satu produk halal yang dikonsumsi oleh muslim adalah produk kosmetik. Berdasarkan survei Zap Beauty Index (2020), ditemukan bahwa 49,5 persen konsumen tidak memerhatikan label halal ketika akan membeli kosmetik. Penelitian ini bertujuan menganalisis faktor-faktor yang memengaruhi minat beli kosmetik halal di Kabupaten Bogor dengan mengambil sampel sebanyak 100 responden. Metode penarikan sampel yang digunakan adalah ¬purposive sampling dan dianalisis menggunakan Structural Equation Model-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa faktor yang signifikan memengaruhi minat beli masyarakat Kabupaten Bogor untuk membeli kosmetik halal adalah sikap, norma subjektif, kesadaran halal, dan religiusitas., Muslims are required to consume halal products. One of the halal products consumed by muslim is cosmetics. Based on the Zap Beauty Index (2020) survey, it was found that 49.5 percent of consumers did not pay attention to halal labels when buying cosmetics. This study aims to analyze the determinant factors of purchase intention of halal cosmetics in Bogor Regency by taking a sample of 100 respondents.

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.
