Judul: Intensi Mahasiswa Program Pendidikan Kompetensi Umum Institut Pertanian Bogor Untuk Membeli Kosmetik Halal.
Abstrak: Pasar kosmetik di Indonesia terus mengalami peningkatan dengan rata-rata pertumbuhan sebesar 9.67 persen dari tahun 2010-2015. Produk kosmetik yang berlabel halal hanya 0.77 persen dari total yang terdaftar di BPOM. Tujuan penelitian ini adalah untuk melihat intensi mahasiswa dalam membeli kosmetik halal. Penelitian dilakukan di Institut Pertanian Bogor (IPB) dengan mengambil sampel sebanyak 60 mahasiswa Program Pendidikan Kompetensi Umum (PPKU) dengan menggunakan teknik Accidental Sampling dan dianalisis menggunakan Partial Least Square-Sturctural Equation Model (PLS SEM). Hasil analisis data menunjukkan bahwa faktor yang signifikan memengaruhi intensi mahasiswa PPKU IPB untuk membeli kosmetik halal adalah norma subjektif dengan indikator yang paling mendominasi lingkungan sosial berupa pengaruh dari teman-teman sesama mahasiswa PPKU IPB.

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. The sampling method used is purposive sampling and analyzed using Structural Equation Model-Partial Least Square (SEM-PLS). The results show that the factors that significantly determine purchase intention in Bogor Regency to buy halal cosmetics are attitude, subjective norm, halal awareness, and religiosity.

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.
