Judul: Online Purchasing Decision Halal Cosmetics by Muslimah in DKI Jakarta
Abstrak: Indonesia memiliki potensi produksi maupun konsumsi produk halal didunia karena penduduk Indonesia terdiri dari mayoritas muslim, separuhnya merupakan wanita. Namun dengan potensi besar tersebut Indonesia belum mampu untuk berada dalam Top 10 Pharma and Cosmetics Producerin Global berdasarkan State of Global Islamic Economy Report 2020. Seiring dengan berkembangnya era digital, pembelian secara online memberikan dampak positif. Namun masih perlu ditelaah mengingat kosmetik impor yang beredar juga semakin meningkat dari seluruh dunia. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen muslimah DKI Jakarta dan menganalisis faktor-faktor dalam pengambilan keputusan pembelian kosmetik halal secara online oleh muslimah di DKI Jakarta. Penelitian ini dilakukan di DKI Jakarta dengan mengambil sampel sebanyak 100 responden. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan analisis regresi logistik. Hasil penelitian menunjukkan bahwa harga berpengaruh signifikan positif terhadap keputusan pembelian kosmetik halal secara online oleh muslimah di DKI Jakarta.

Judul: Keputusan Pembelian Kosmetik Halal Oleh Muslimah Kota Bogor Selama Pandemi COVID-19
Abstrak: Indonesia sebagai negara mayoritas muslim terbesar di dunia merupakan pasar potensial bagi produk halal termasuk kosmetik. Namun, akibat pandemi COVID-19 kinerja industri kosmetik di Indonesia mengalami penurunan termasuk kosmetik halal. Penelitian ini bertujuan untuk mengetahui keputusan pembelian kosmetik halal oleh muslimah Kota Bogor selama masa pandemi. Sampel penelitian ini berjumlah 100 responden mewakili muslimah Kota Bogor dan pengambilan data menggunakan kuesioner dengan skala likert. Analisis data menggunakan statistik deskriptif dan regresi logistik. Berdasarkan hasil analisis statistik deskriptif karakteristik muslimah pada penelitian ini didominasi dengan usia 15 tahun hingga 25 tahun dan membeli kosmetik halal selama pandemi didominasi oleh responden pada usia 15 tahun – 25 tahun. Berdasarkan hasil analisis regresi logistik variabel promosi, tren dan halal awareness memiliki peluang yang signifikan terhadap keputusan pembelian kosmetik halal selama masa pandemi., Indonesia as the largest Muslim country in the world is a potential market for halal products, including cosmetics. However, due to the COVID-19 pandemic, the performance of the cosmetic industry in Indonesia has decreased, including halal cosmetics. This study aims to determine the decision to purchase halal cosmetics by Muslim women in Bogor City during the pandemic. The sample of this study amounted to 100 respondents representing Muslim women in the city of Bogor and data collection using a questionnaire with a Likert scale. Data analysis used descriptive statistics and logistic regression. Based on statistical analysis of the characteristics of Muslim women in this study, they were dominated by the age of 15 years to 25 years and halal cosmetics during the pandemic were dominated by respondents at the age of 15 years to 25 years. Based on the results of the logistic regression analysis of promotion variables, trends and awareness of halal have a significant opportunity to purchase halal cosmetics during the pandemic.

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.
