Abstrak: Omega-3 egg is modificated egg with higher nutrition content than conventional egg and has a lot benefits for health and intelligence. This study aimed to identify public perception on omega-3 egg and its benefits by dividing them into several categories. There were 50 selected sample of respondents having knowledge about omega-3 eggs which are also divided into five characteristic. There are pregnant women, infants mother, educated at least bachelor people, disease susceptible age (45-60) years, and the elderly (> 60) years. Respondents were given eleven questions about the advantages of omega-3 egg and five choices of virtues in consuming omega-3 eggs. The result indicated that all categories of respondents agree with all the advantages of omega-3 eggs. While, the virtue in consuming omega-3 eggs are chosen selected by respondents were toddlers intelligence. In conc1usion,the study has showed that society in Bogor area received omega-3 egg products as adventageous products for health and brain intelligence

Judul: Perilaku Konsumen dalam Aktivitas Pembelian Telur Omega-3 di Beberapa Supermarket di Kota Bogor
Abstrak: Omega-3 egg is egg that contains more omega-3 than conventional egg but still not too popular in society. The aim of this study was to identify consumer behavior towards purchasing activity omega-3 egg in several categories supermarket in Bogor City. This study conducted in 26 August – 26 September 2013 in 6 supermarkets namely Ramayana Tanah Sareal, Lotte Mart Cimanggu, Yogya Cimanggu, Giant Yasmin, Giant Botani Square and Superindo Jembatan Merah. There were 60 selected samples were divided 10 samples supermarket-1. This study used non randomized sampling method. Consumer in Bogor city have known the information about omega-3 egg from print media, buy it from supermarket purpose to consumed, all family member consume but not rutine, amount of eggs 10 eggs purchase-1, brown egg shell is preferred, the most preferred packaging was plastic mica, egg price 2.500 rupiah egg-1 and respondents thought that omega-3 egg price expensive.

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.
