Judul: Perancangan Media Informai Online dan Offline Usaha Ternak Ayam Kampung Berbasiskan Web (studi Kasus di P4S Eka Jaya di Jakarta Selatan)
Abstrak: Sampai saat ini belum ada batasan yang pasti tentang pengertian ayam kampung. Jika di sini disebut-sebut kata “ Ayam Kampung ”, penyebutan ini hanya sekedar untuk menunjukan jenis ayam lokal dengan keragaman genetis tinggi yang sudah dikenal luas dan tersebar di berbagai wilayah Indonesia. Jenis ayam lokal ini diperkirakan menjadi variasi karena pengaruh isolasi tempat. Variasi individu dalam satu jenis ini tidak hanya terbatas pada warna bulu, tetapi juga pada ukuran tubuh, produktivitas telur dan suara. Media informasi online (internet) dan offline (cakram padat) dapat digunakan sebagai salah satu medium komunikasi massa. Saluran komunikasi massa merupakan alat melalui mana sumber komunikasi menyampaikan pesan-pesan kepada penerima. Melalui media ini, diharapkan penerima dapat memperoleh informasi tentang ayam kampung dengan mudah. Disaat tidak dapat menggunakan internet, pengguna dapat memanfaatkan cakram padat sebagai sumber informasi.

Judul: Perancangan media informasi online dan offline usaha ternak ayam kampung berbasiskan web:studi kasus di P4S Eka Jaya, di Jakarta Selatan
Abstrak: The purposes of the research are (1) studying the information system design or web design as media that transfer any informations needed by native chicken’s breeder (2) studying the advantages of compact disk technology used as media of informations that is needed by native chicken’s breeder and (3) identifying and presenting any kind of data and informations related to native chicken’s breeder by means of software engineering.The research has five stages, they are :(1) the stage of identifying a system (2) the stage of analyzing a system and data collecting (3) designing and planning a system (4) making web and (5) maintenance. The research will be done by comparing some web systems which are populerly known as Content Management Systems (CMS). All of those Content Management Systems have some similarities, especially of system used. Those similarities are that they use PHP programming language and MySQL database server. Both are entirely open source. The research has sought data from P4S Eka Jaya chicken farming which locate at jagakarsa in South Jakarta. These data have been used as the contents of the web pages. As the result, there are four CMS recommended as the Web System to be used as online or offline web-based information media. They are Joomla, Mambo CMS, Word Press, and PHP nuke.The final results of the research may be observed on http://www.ayamkampoeng.net and also on Compact Disk.

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.
