Judul: Perancangan User Experience Mahasiswa pada Repositori Institusi IPB Berbasis Mobile Menggunakan Metode Lean UX.
Abstrak: Repositori Institusi adalah wadah penyimpanan koleksi digital untuk menyimpan dan mempertahankan kekayaan intelektual dari sebuah institusi secara menyeluruh dan sistematis. Perancangan user experience Repositori Institusi IPB sudah dilakukan dari segi tampilan desktop namun pada aplikasi mobile masih menggunakan tampilan Responsive Web Design sehingga terdapat banyak konten yang tidak diperlukan bagi mahasiswa, tetapi tetap ditampilkan dalam aplikasi. Penelitian ini berfokus pada perancangan user experience mahasiswa pengguna Repositori Institusi IPB berbasis mobile dengan memerhatikan aspek user experience menggunakan metode Lean UX. Metode ini memudahkan proses perancangan user experience secara cepat dan tepat sasaran. Tahap perancangan dilakukan dengan 4 tahapan, yaitu declare assumptions, create minimum viable products, run an experiments, dan feedback and research. Tahapan ini memiliki keterhubungan satu sama lain sehingga membentuk sebuah siklus yang nantinya akan dilakukan dua kali pengulangan untuk penelitian ini. Prototipe sudah diuji kepada 5 orang mahasiswa dengan tingkat akurasi success rate pada task sebesar 86.7% serta telah diperbaiki berdasarkan saran dan masukan dari pengguna.

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: 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.
