Judul: Perbandingan Arsitektur Informasi Repositori Institusi Terbaik di Indonesia dan Dunia
Abstrak: Sistem perangkingan repositori dapat dinilai sebagai cara untuk meningkatkan kinerja setiap institusi. Sistem perangkingan yang digunakan dalam penelitian ini berbasis Webometric versi Januari 2017. Arsitektur informasi berfokus pada sistem organisasi, sistem navigasi, sistem pelabelan dan sistem pencarian. Tujuan arsitektur informasi adalah untuk membantu pengguna mendapatkan informasi dan penyelesaian tugas. Penelitian ini menekankan kepada perbandingan kualitas arsitektur informasi pada repositori terbaik di dunia dan di Indonesia. Hasil analisis menunjukkan bahwa dari 10 menu yang paling banyak digunakan oleh repositori di Indonesia lebih cenderung menampilkan koleksi dokumen melalui menu document (collection) dengan nilai 154 sementara repositori di dunia lebih cenderung menampilkan berbagai macam pelayanan melalui menu service dengan nilai 242.

Judul: Analisis Arsitektur Informasi Situs Web Universitas Terbaik di Dunia dan Indonesia Berbasis Webometrics
Abstrak: University ranking system can be considered as a method to improve the performance at each university. Two popular university ranking systems can be viewed on the site Webometrics and QS World University Rankings. There are three things that affect the rank of universities,i.e,the information architecture, the quality of the content of information, and the activities of the universities. This research emphasizes on the information of architecture by comparing the architecture of information on universities in the world and universities in Indonesia. Menus on the website of 10 universities in the world and 10 universities in Indonesia are compared based on the search level and position the menu located on each website. From the entire menu, only 30 menus are analyzed based on the highest weight values. The analysis showed that the universities in Indonesia are more likely to provide profile information, while universities in the world put forward the research and development based on user information.

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.
