Judul: Kajian User Experience pada Repositori Institusi Institut Pertanian Bogor
Abstrak: Institutional Repositories adalah platform pengelolaan asset pengetahuan untuk membantu institusi mengatur ruang penyimpanan yang berpusat dengan tujuan mengoleksi, mengatur, menampilkan, melestarikan dan menyebarkan artefak pengetahuan secara sistematis. Repositori IPB merupakan salah satu repositori kampus terbaik di Indonesia. Pengembangan Repositori IPB sebelumnya hanya memerhatikan dari segi fungsionalitas, sehingga masih banyak beberapa task dan konten yang dianggap membingungkan pengunjung dalam mencari suatu dokumen pada Repositori IPB. Penelitian ini berfokus pada pengembangan Repositori IPB yang memerhatikan aspek user experience (UX) menggunakan metode five plane user experience elements. Metode tersebut memiliki lima lapisan yang memiliki keterkaitan antar lapisannya. Tahap pengembangan dilakukan dari lapisan bawah menuju lapisan atas, meliputi lapisan strategy plane, scope plane, structure plane, skeleton plane dan surface plane, Setelah penelitian ini diharapkan Repositori IPB bisa mendapatkan respon yang baik dari admin dan pengunjung dengan meningkatkan layanan yang memerhatikan UX sehingga branding dan pengunjung Repositori IPB bisa terus meningkat., Institutional Repositories is a knowledge asset management platform to help institutions organize centered storage space with the purpose of collecting, organizing, displaying, preserving and disseminating knowledge artifacts in a systematic. Repository IPB is one of the best institutional repositories in Indonesia. Development of IPB Repository previously only noticed in terms of functionality, so many multiple tasks and content considered to confuse the visitor in finding a document on IPB Repository. This research will be focusing in aspect of user experience (UX) using five planes user experience elements to development IPB Repository. The method has five layers that have linkages between the layers. The development phase is done from the bottom layer to the upper layer, includes layer strategy plane, scope plane, structure plane, skeleton plane and surface plane. After this research will expect Repository IPB can get a good response from the admin and visitors by improving services noticed UX so that branding and visitors Repository IPB increase significantly.

Judul: Studi Kelayakan Pengembangan Repositori Institusi: Studi Kasus Institut Teknologi Del
Abstrak: Institutional repository is a repository of digital collections published by institutions. Institutional repository is important as a container store and preserve collections produced by the institution. However, before developing the institutional repository feasibility study needs to ensure that the development process will be able to run well. The purpose of this study is to assess/feasibility study analysis in the development of institutional repositories at ITD and make a recommendation for the development of institutional repositories at ITD. Institutional repository element studied is the infrastructure, human resources, budget, rules/SOP, and content. IPB repositories use as a model in this research. The method used is knowledge management systems (KMS) in stages 1 and 2. Weighting interests repository elements using AHP (Analytic Hierarchy Process). The weighting for each component element of institutional repository based on the opinion of experts, the assessment of the four elements are as follows institutional repository infrastructure (22.23%), content (21.32%), rule / SOP (20.00%), human resources (19.36%), budget (16.99%). Based on the weighting that the most important component in building repository is infrastructure and the last one is the budget. Based on the analysis of the feasibility of the ITD infrastructure percentages obtained in building institutional repositories amounted to 51.96%. The percentage is derived from the percentage of the value of the following eligibility is infrastructure (21.44%), human resources (14.33%), budget (0%), rules / SOP (3.40%), and content (12.79%). While the results of the alignment of the management of knowledge shows that knowledge in IPB and ITD focuses on strategies codification where codification in IPB done by (89%) and in the ITD by (78%). This shows that both IPB and ITD focus on storage technology knowledge management, indexing, retrieval and reuse of knowledge that is stored. Furthermore, if the IPB has had a team in developing the knowledge, the ITD has the potential to have a team that consists of a collaboration between Library and Resource Information Team (SDI) ITD. The results of the study referred to the several things that need to be ordered in the effort to develop the institutional repository ITD and refer to the model repository development in IPB is to provide the infrastructure that is software as a tool for transferring media content repository, making decree for institutional repository development team, create standard operational procedure for digital documents and the handover of the scientific work of the academic community ITD and make decree for deposit of scientific work and submit a budget for activities of institutional repository.

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.
