Judul: Analisis Faktor-Faktor yang Mempengaruhi Perilaku Konsumen dalamKeputusan Pembelian Susu Cair Ultra Milk (Studi Kasus Mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Indonesian people’s growing awareness of the impotance of liquid milk as a product for maintaining health, brings about an opportunity of marketing a product of liquid milk. A liquid milk industry is in fact dominated by popular players, among other things, Ultra Milk. Therefore, to maintain its market, Ultra Milk is supposed to know the factors influencing the making of the desicion of buying liquid milk. The consumers who have become a research target is a student of bachelor degree of Bogor Institute of Agriculture who has bought some liquid milk of Ultra Milk. This research is intended to as follows : (1) to identify the characteristic of the costumers of Ultra Milk, (2) to identify a process of deciding to buy Ultra Milk, (3) to analyze the factors influencing the customers’ decision to buy Ultra Milk, (4) to analyze customers attitude towards the attributes owned by Ultra Milk. The data used in this research are primary and secondary. The primary data are taken from the spreading of questionaires and the secondary data are taken from a library study, information on the internet, and a study of references. Secondary data are taken frombook’s study, internet and literature’s study.The technique to take samples used in this research is a quota sampling. The means of analyzing are the descriptive analysis, the factor analysis and a model of MultiattributeFishbein analysis with the help of SPSS software version 17 and Microsoft Excel. The results of the research show that the majority of the customers of Ultra Milk’s liquid milk are the female university students (62%), aged 21 years old (46%), their origins of Jakarta, Bogor, Tangerang and Bekasi (41%). Their average monthly expenses are from 500,001 rupiahs to 1,000,000 rupiahs ( 67%). The process to decide on buying the customers of Ultra Milk’s liquid milk goes through 5 phases namely, recognizing the need, searching for the information, evaluating the alternatives, buying and evaluating the. Referring to the factor analysis, there are 3 factors which are seen, among other things, the factors of individual characteristic, the knowledge of a product and a personality, and the source of information. Referring to the analysis of multiattributeFishbein, the customers put emphasis on the halal of a product, the quality of product and the security of a consuming process while buying liquid milk. The customers see Ultra Milk’s liquid milk from the quality of a product, the halal of a product and the security of a consuming process. Referring to the Fishbein score of 258.68, it is concluded that the product of Ultra Milk’s liquid milk is considered as a good category.

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.
