Judul: Pengembangan Modul Back End Himpunan Alumni pada Aplikasi IPB Connect.
Abstrak: Menurut Statuta Insitutut Pertanian Bogor, adan alumni memiliki hubungan yang memeliki hubungan sepanjang masa. Dengan potensi alumni sebesar 122.932 orang dan alumni adalah pilar penting dalam kemajuan almamater, Himpunan Alumni memiliki tugas penting. Himpunan Alumni diharapkan mampu meneruskan menjadi jembatan antara alumni dan kampus. Penelitian ini mengembangkan aplikasi IPB Connect, yang bermanfaat untuk meningkatkan peran Himpunan Alumni IPB. Aplikasi ini dikembangkan menggunakan metode prototyping dengan arsitektur REST API. Node.js dengan framework Express.js menjadi bahasa pemrograman yang digunakan dan didukung dengan basis data MongoDB. Yang dikembangkan pada aplikasi ini hanya aplikasi server-side yang nantinya akan menghasilkan web services untuk dikonsumsi aplikasi client-side. Hasil pengembangan menghasilkan API yang bisa diakses di api.stage.ipb.ac.id dan sesuai dengan yang dibutuhkan pengembang aplikasi client-side.

Judul: Pengembangan Modul Back End pada Aplikasi IPB Connect Menggunakan Metode Prototyping.
Abstrak: IPB memiliki organisasi yang memfasilitasi hubungan antara alumni dan mahasiswa, yaitu Himpunan Alumni IPB. Himpunan Alumni IPB perlu sebuah aplikasi untuk mempermudah hubungan komunikasi antara alumni dan mahasiswa, sehingga dikembangkanlah aplikasi IPB Connect. Aplikasi tersebut sudah dikembangkan di penelitian sebelumnya tetapi masih dalam tahap pengembangan. Maka dari itu, aplikasi IPB Connect harus dikembangkan lebih lanjut baik dari sisi back end maupun sisi front end. Pengembangan modul back end pada aplikasi IPB Connect dikembangkan menggunakan metode prototyping. Lingkungan pengembangan yang digunakan, yaitu bahasa pemrograman Node.js, kerangka kerja Express.js, basis data MongoDB, dan arsitektur REST. Pengembangan modul back end akan menghasilkan API dengan arsitektur REST yang akan digunakan oleh tim front end dalam pengembangan antarmuka aplikasi IPB Connect. Pengembangan modul back end pada aplikasi IPB Connect selesai dalam dua iterasi metode prototyping dan sudah dapat digunakan untuk memenuhi kebutuhan tim front end.

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.
