Judul: Mobile Mashup Informasi Objek Wisata Kota Bogor dengan Location Based Service Sebagai Query
Abstrak: Aplikasi berbasis mobile sudah menjadi kebutuhan wisatawan untuk memberikan kemudahan dalam akses informasi atau transaksi seperti navigasi, informasi destinasi wisata, booking hotel, dan booking pesawat. Penelitian ini dilakukan untuk membangun aplikasi berbasis mobile dengan konten informasi wisata kota Bogor. Informasi lokasi wisata kota Bogor didapatkan dari beberapa API yang dikombinasikan untuk memberikan gambaran informasi dalam bentuk yang lain. Informasi yang muncul pada aplikasi dipicu oleh posisi perangkat dengan objek wisata yang jaraknya paling dekat dengan posisi pengguna. Jarak yang diperoleh dari posisi pengguna menuju objek wisata menggunakan algoritme haversine. Evaluasi aplikasi ini meliputi kenyamanan pengguna aplikasi dengan pendekatan ukuran user interface satisfaction yang diuji oleh 10 responden. Hasil menunjukkan pada angka 79.69% (masuk pada interval memuaskan

Judul: Mobile Mashup Informasi Objek Wisata Indonesia
Abstrak: Mashup is a web application that allows one to integrate information from several companies to create a new or more helpful product information. Nowadays, mobile phone that is being used as a communication tool, is also used as a navigation tool to give directions on the map from the initial position to a certain destination. The position information of various interesting tourism objects in Indonesia is very important to inform the users about the location of the desired tourism object. This research aims to develop a mobile phone mashup application for the information of tourism objects in Indonesia. Information provided includes description, location, videos, photos, hotels, news, and books of the related tourism objects. Trackpacking, Wego, Google, Flickr, and Youtube were used as the sources of information to obtain the data. Model data passing style with blackboard approach was used to merge the data, in which the source data is written to the variable which is used by the interface component to generate information that will be displayed to the user. The results of the tests performed on this application produced 90% of the successful display of information. However, the application only showed 70% level of relevance between the query and information displayed, due to the lack of data and the more specific query.

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.
