Judul: Pengembangan Sistem Informasi Himpunan Alumni IPB Berbasis Website Menggunakan Metode Prototyping
Abstrak: Alumni merupakan sebuah bagian yang tidak bisa terpisahkan dari sebuah akademik. Namun banyak dari mereka yang sudah menjadi alumni tapi sangat sulit bagi mereka untuk mencari informasinya. Maka dari itu aplikasi Himpunan Alumni IPB ini dikembangkan agar memudahkan para alumni untuk mencari informasi tentang alumni lainnya dan juga sebagai sarana silaturahmi. Pengembangan sistem informasi ini diharapkan dapat memudahkan para alumni untuk saling bertukar informasi dan lainnya yang dirasa perlu untuk disajikan pada saat dibutuhkan. Fitur utama yang dikembangkan pada sistem informasi ini adalah alumni IPB bergabung ke dalam himpunan alumni ipb sesuai dengan domisili daerahnya saat ini. Pengembangan sistem informasi ini menggunakan framework Laravel dan menggunakan bahasa pemrograman PHP. Metode yang digunakan pada pengembangan sistem informasi ini adalah metode prototyping., Alumni are an inseparable part of an academic. However, many of them are already alumni but it is very difficult for them to find information. Therefore the IPB Alumni Association application was developed to make it easier for alumni to find information about other alumni and also as a means of friendship. The development of this information system is expected to make it easier for alumni to exchange information and others that are deemed necessary to be presented when needed. The main feature developed in this information system is that IPB alumni join the IPB alumni association according to their current branch of domicile. The development of this information system uses the Laravel framework and uses the PHP programming language. The method used in the development of this information system is the prototyping method.

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: 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.
