Judul: Faktor-Faktor yang Memengaruhi Preferensi Remaja di Kota Bogor dalam Memilih Kafe dan Restoran Bersertifikat Halal.
Abstrak: Jumlah kafe dan restoran di Kota Bogor terus mengalami peningkatan dan salah satu konsumen potensialnya adalah remaja. Remaja merupakan konsumen kafe maupun restoran dan sudah masuk kategori mukallaf (wajib mematuhi perintah Allah SWT termasuk untuk mengonsumsi makanan halal). Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi preferensi remaja di Kota Bogor terhadap kafe dan restoran bersertifikat halal. Penelitian ini dilakukan dari November 2017 hingga Juli 2018 di SMA Negeri 1, SMA Negeri 3, SMA Negeri 4, SMA Negeri 6, dan SMA Negeri 7 dengan jumlah responden sebanyak 150 orang. Pengambilan sampel menggunakan teknik Purposive Sampling dengan analisis data menggunakan metode regresi logistik dan analisis deskriptif. Hasil analisis data menunjukkan bahwa faktor-faktor yang memengaruhi preferensi remaja terhadap kafe dan restoran bersertifikat halal adalah pengetahuan, religiusitas, dan lingkungan sosial.

Abstrak: Perkembangan industri halal saat ini mengalami kemajuan yang sangat pesat, termasuk pertumbuhan industri makanan dan minuman yang menyasar konsumen muslim. Hal ini didukung oleh peningkatan populasi Muslim di dunia. Kopi merupakan salah satu minuman yang digemari diseluruh dunia, termasuk di Indonesia. Perubahan gaya hidup masyarakat yang mengarah pada budaya minum kopi di coffee shop mulai mengalami peningkatan berbanding lurus dengan adanya peningkatan konsumsi kopi di Indonesia. Kalangan masyarakat baik remaja maupun orang dewasa mulai gemar untuk datang ke coffee shop untuk menikmati kopi dan menu coffee shop lainnya. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan konsumen membeli produk coffee shop berlabel halal di Kota Bogor. Metode yang digunakan dalam penelitian ini yaitu analisis deskriptif dan analisis regresi logistik. Hasil penelitian menunjukkan bahwa faktor-faktor yang memengaruhi keputusan konsumen membeli produk coffee shop berlabel halal di Kota Bogor secara signifikan dipengaruhi oleh religiusitas, harga, dan fasilitas., The development of halal industry is currently experiencing very rapid progress, including the growth of the food and beverage industry which targets Muslim consumers. This is supported by the increasing of Muslim population in the world. Coffee is one of favorite drinks around the world, Indonesia included. People's lifestyle changes that lead to a culture of drinking coffee in coffee shops have begun to increase in parallel with the increase in coffee consumption in Indonesia. The community, both teenagers and adults, is starting interested in to come to the coffee shop to enjoy coffee and other coffee shop’s menus. The purpose of this research is to analyze factors that affecting consumers’s decisions to buy halal labeled coffee shop products in Bogor City. This research used descriptive analysis and logistic regression analysis methods. The results show that the factors that significantly affect consumer decisions to buy halal labeled coffee shop products in Bogor City are religiosity, price, and facilities.

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.
