Judul: Pengaruh Social Media Influencer terhadap Keputusan Pembelian Produk Kecantikan Halal pada Generasi Z di Jabodetabek
Abstrak: Di Indonesia, kosmetik halal menjadi salah satu sektor industri halal yang sedang berkembang dan menempati posisi ke-2 di dunia. Kosmetik halal saat ini banyak diperhatikan oleh masyarakat khususnya remaja yang dikenal dengan nama generasi Z. Tujuan penelitian ini adalah untuk menganalisis pengaruh religiusitas, label halal, harga, kualitas dan social media influencer terhadap keputusan pembelian produk kecantikan halal pada generasi Z di Jabodetabek. Sampel penelitian ini berjumlah 114 responden yang mewakili generasi Z di Jabodetabek dan pengambilan data menggunakan kuesioner dengan skala Likert. Metode analisis data yang digunakan ialah metode regresi linear berganda dengan teknik pengambilan sampel menggunakan purposive sampling. Hasil menunjukkan bahwa secara bersama variabel independen berpengaruh signifikan terhadap keputusan pembelian. Secara parsial, harga dan kualitas produk berpengaruh terhadap keputusan pembelian sedangkan religiusitas, label halal dan social media influencer tidak berpengaruh., In Indonesia, halal cosmetics are one of the growing halal industrial sectors, occupying the 2nd position in the world. Halal cosmetics are currently getting a lot of attention from the public, especially teenagers, known as Generation Z. The purpose of this study was to analyze the effect of religiosity, halal label, price, quality and social media influencers on purchasing decisions for halal beauty products in Generation Z in Jabodetabek. The sample of this study amounted to 114 respondents representing generation Z in Jabodetabek and data collection using a questionnaire with a Likert scale. The data analysis method used in this research is multiple linear regression method with sampling technique using purposive sampling. The results show that simultaneously the independent variables have a significant effect on the dependent variable. Partially, price and product quality influence purchasing decisions, while religiosity, halal labels and social media influencers have no 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.
