Judul: Faktor-faktor yang Memengaruhi Keputusan Konsumen  Muslim DKI Jakarta dalam Membeli Suplemen Kesehatan Berlabel Halal
Abstrak: Halal tidak hanya sebatas pada makanan dan minuman saja, tetapi juga untuk semua kebutuhan hidup lainnya, termasuk produk farmasi suplemen kesehatan. Menurut LPPOM MUI, suplemen kesehatan perlu dicermati kehalalannya karena tidak semua produk suplemen sudah bersertifikat halal dan memiliki beberapa titik kritis kehalalan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dan persepsi konsumen muslim mengenai keberadaan label halal pada suplemen kesehatan serta menganalisis faktor-faktor yang memengaruhi keputusan pembelian terhadap produk suplemen kesehatan berlabel halal. Penelitian dilakukan di DKI Jakarta dengan mengambil sampel sebanyak 100 responden. Metode yang digunakan yaitu analisis deskriptif dan analisis regresi logistik. Hasil penelitian menunjukkan bahwa pengetahuan halal, halal awareness, harga, kualitas produk dan pendapatan berpengaruh signifikan terhadap keputusan konsumen muslim DKI Jakarta dalam membeli suplemen kesehatan berlabel halal., Halal is not only limited to food and beverages, but also for all other necessities of life, including dietary supplements, which are pharmaceutical products. According to LPPOM MUI, halal dietary supplements need to be observed because not all supplement products are halal certified and have several critical points of halalness. This study aims to identify and perceive Muslim consumers regarding the existence of halal labels on health supplements and analyze the factors that influence purchasing decisions for health supplement products labeled halal. The study was conducted in DKI Jakarta by taking a sample of 100 respondents. The methods used are descriptive analysis and logistic regression analysis. The results show that halal knowledge, halal awareness, price, product quality, and income have a significant effect on the decisions of Muslim consumers in DKI Jakarta when buying dietary supplements labeled halal.

Judul: Faktor-faktor yang Memengaruhi Keputusan Pembelian Makanan  Kemasan Berlabel Halal Masyarakat Muslim Kota Bekasi
Abstrak: Makanan kemasan merupakan produk terbanyak yang beredar di masyarakat, namun belum semuanya telah berlabel halal. Hampir seluruh kalangan masyarakat mengonsumsi makanan kemasan, termasuk pekerja pabrik dan pelajar. Penelitian ini bertujuan untuk menganalisis faktor-faktor pengambilan keputusan pembelian makanan kemasan berlabel halal masyarakat muslim Kota Bekasi. Penelitian ini dilakukan di Kota Bekasi dengan mengambil sampel sebanyak 100 responden menggunakan purposive sampling. Metode analisis data yang digunakan adalah regresi linear berganda. Hasil penelitian menunjukkan bahwa secara bersama variabel independen berpengaruh signifikan terhadap keputusan pembelian. Secara parsial, health reason dan merek berpengaruh terhadap keputusan pembelian sedangkan pengetahuan produk halal, halal awareness dan religiusitas tidak berpengaruh.

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.
