Tingkat pengetahuan konsumen mengenai sertfikasi dan label halal sudah cukup baik. Hasil analisis mengunakan metode crosstab dan chi-square test menunjukkan bahwa pengetahuan produk halal, norma subjektif dan kesadaran halal yang didalamnya terdapat poin penting mengenai label halal berpengaruh positif secara signifikan terhadap keputusan pembelian konsumen., Currently, halal products are becoming a consumption trend for various groups, both in Indonesia and outside Indonesia. Not all of the food products sold online are definitely halal food products. These problems resulted in the existence of Muslim communities who were trapped when they wanted to buy these food products. The existence of halal labels in product packaging will make it easier for consumers to identify products that are suitable for consumption or not especially for Muslim consumers. This study aims to determine consumer awareness of halal labels in purchasing food products online in Jabodetabek. The method used is the survey method. The total population is 18,928,217 people and the number of samples used is 236 people. The sample was determined by the convenience sampling method. The data used in this study were analyzed using descriptive analysis to identify the level of consumer knowledge about halal certification and labeling. Crosstab and chi-square test analysis methods are used to analyze independent variables, namely knowledge of halal products, halal awareness, subjective norms that influence the dependent variable purchasing decisions. The level of consumer knowledge regarding halal certification and labeling is quite good. The results of the analysis using the crosstab and chi-square test methods show that knowledge of halal products, subjective norms and halal awareness in which there are important points regarding halal labels have a significant positive effect on consumer purchasing decisions.

Judul: Behavior Analysis and Clustering of Restaurant Consumers Towards Halal Awareness In JABODETABEK
Abstrak: Tingginya populasi umat Islam di Indonesia membuat isu halal menjadi hal yang sensitif bagi masyarakat Indonesia. Terutama isu lemak babi yang terdapat pada produk makanan yang dijual bebas di Indonesia merebak menjadi bahan perbincangan masyarakat Indonesia. Hal ini yang melatarbelakangi dibuatnya Lembaga Pengkajian Pangan Obat-obatan dan Kosmetika - Majelis Ulama Indonesia untuk melakukan pemeriksaan dan sertifikasi halal. Namun, restaurant di Indonesia banyak yang belum memiliki sertifikasi halal yang membuat kurangnya awarenss masayrakat terhadap halal. Penelitian ini bertujuan menganalisis faktor yang mempengaruhi behavior dan mengetahui cluster konsumen terhadap halal awareness dalam memilih restoran di Jabodetabek. Selain itu penelitian ini juga menganalisis implikasi manajerial untuk meningkatkan halal awareness. Penelitian ini menggunakan pendekatan kuantitatif dengan populasi konsumen yang berdomisili di Jabodetabek. Teknik analisis dilakukan dengan memanfaatkan Microsoft Excel untuk analisis deskriptif, uji validitas dan reliabilitas. SmartPLS untuk analisis hubungan antar variabel dan cluster analysis menggunakan software WEKA. Hasil penelitian menunjukan faktor yang mempengaruhi perilaku konsumen dalam memilih restoran diantaranya subjective norm, perceived behavior control, halal awareness dan intention terhadap behavior secara positif dan signifikan. Sementara attitude toward behavior tidak berpengaruh signifikan terhadap behavior konsumen dalam memilih restoran bersertifikat halal. Cluster konsumen yang terbentuk 3 cluster dimana cluster 1 responden yang kurang memiliki intention terhadap restoran halal dan kurang aware terhadap halal. Cluster 2 konsumen yang memiliki intention terhadap restoran halal dan aware terhadap halal dan cluster 3 konsumen yang memiliki intention terhadap restoran halal sangat tinggi dan awareness terhadap halal yang tinggi. Implikasi manajerial pada cluster 1 peran yang paling penting untuk meningkatkan halal awareness konsumen adalah peran pelaku usaha dan pemerintah yang diwakili oleh BPJPH. Cluster 2 dibutuhkan peran BPJPH yang bersinergis dengan BPOM untuk membuat aturan baru mengenai penanda terhadap setiap restoran. Pada cluster 3 pelaku usaha berperan menjaga prosedur halal dan konsumen berperan merekomendasikan restoran-restoran halal., Due to Indonesia's large Muslim population, the halal issue is a sensitive topic for Indonesians. In particular, the presence of lard in freely available food products in Indonesia has become a topic of conversation among Indonesians. This is the rationale behind the establishment of the Indonesian Ulema Council for halal inspection and certification. However, many restaurants in Indonesia lack halal certification, resulting in a lack of halal awareness among the general public. This study aims to examine the factors that influence consumer behavior and clusters of halal awareness in Jabodetabek when selecting a restaurant. In addition, the managerial implications of increasing halal awareness are analyzed in this study. This study employs a quantitative methodology with a population of Jabodetabek-based consumers. Microsoft Excel are utilized for descriptive analysis, test of validity, and test of reliability by the analysis technique. SmartPLS for analyzing the relationship between variables and cluster analysis using the WE KA software. The findings revealed that subjective norms, perceived behavior control, halal awareness, and behavior intention are positively and significantly related to consumer restaurant choice. In contrast, consumers' selection of halal-certified restaurants is not substantially influenced by their attitudes toward behavior. Three consumer clusters were identified, with cluster 1 respondents requiring more intention toward halal restaurants and less knowledge of halal. In cluster 2, the

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.
