Judul: Factors That Influence The Purchase Decision of Generation Z Muslims towards Non Halal Labeled Cosmetic Products in Kabupaten Bogor
Abstrak: Produk halal memiliki peran penting di Indonesia, termasuk dalam industri kosmetik. Namun, tidak semua produk kosmetik yang beredar di Indonesia memiliki label halal dari Majelis Ulama Indonesia (MUI). Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian generasi Z Muslim terhadap produk kosmetik tanpa label halal di Kabupaten Bogor. Sampel penelitian terdiri dari 100 responden yang mewakili generasi Z di Kabupaten Bogor, Indonesia. Data dikumpulkan melalui kuesioner dengan skala Likert, dan analisis data menggunakan regresi linear berganda. Penelitian ini menemukan bahwa citra merek, kualitas produk, dan media sosial secara signifikan memengaruhi keputusan pembelian generasi Z Muslim terhadap produk kosmetik tanpa label halal. Namun, religiusitas dan halal awareness tidak memiliki pengaruh signifikan., Halal products have an important role in Indonesia, including in the cosmetic industry. However, not all cosmetic products circulating in Indonesia have a halal label from Majelis Ulama Indonesia (MUI). This study aims to analyze the factors that influence the purchasing decisions of Muslim Z generations for cosmetic products without a halal label in Bogor Regency. The research sample consisted of 100 respondents representing Generation Z in Bogor Regency, Indonesia. Data was collected through a questionnaire with a Likert scale, and data analysis used multiple linear regression. The result found that brand image, product quality, and social media significantly influence the purchase decision of Muslim Z generation for cosmetic products without a halal label. However, religiosity and halal awareness do not have a significant effect

Judul: Faktor-faktor yang Memengaruhi Keputusan Pembelian Generasi Z Muslim Terhadap Produk Kosmetik Berlabel Halal MUI (Studi Kasus Kota Bogor)
Abstrak: Seluruh produk yang masuk, beredar dan diperdagangkan di wilayah Indonesia harus terjamin kehalalannya dan memiliki sertifikat halal tidak terkecuali produk kosmetik. Kosmetik saat ini telah digunakan oleh remaja wanita atau generasi Z. Produk kosmetik yang beredar di Indonesia sangat banyak tetapi tidak semua memiliki label halal MUI. Pada tahun 2018 jumlah produk kosmetik yang sudah berlabel halal hanya sebanyak 2 115 produk dari 49 557 produk kosmetik yang telah mendapat izin edar dari BPOM. Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik generasi Z dan mengetahui faktorfaktor yang memengaruhi keputusan pembelian generasi Z muslim terhadap produk kosmetik berlabel halal. Penelitian dilakukan di Kota Bogor dengan mengambil sampel sebanyak 70 responden dengan menggunakan teknik purposive sampling. Metode analisis data yang digunakan pada penelitian ini adalah analisis regresi logistik. Hasil penelitian ini menunjukkan bahwa pengetahuan halal, halal awareness, dan media sosial berpengaruh positif signifikan terhadap keputusan pembelian generasi Z muslim terhadap produk kosmetik berlabel halal.

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.
