Judul: Sistem Informasi Manajemen Asrama Program Pendidikan Kompetensi Umum Institut Pertanian Bogor
Abstrak: Mahasiswa Program Pendidikan Kompetensi Umum (PPKU) diwajibkan tinggal di asrama Institut Pertanian Bogor (IPB) sejak tahun 2002. Oleh karena itu, asrama PPKU IPB perlu dikelola dengan baik. Adapun pengelolaan yang dimaksud adalah pengelolaan penghuni asrama serta pengelolaan sarana dan prasarana. Tujuan dari penelitian ini adalah membangun sistem informasi manajemen asrama yang disebut SIRAMA. Metode yang digunakan untuk mengembangkan SIRAMA adalah metode prototyping. Metode ini memiliki tahapan-tahapan yang diawali dengan mengidentifikasi kebutuhan bisnis asrama, mengembangkan prototipe, merevisi prototipe, serta implementasi dan perawatan. SIRAMA yang telah dibuat menyediakan fitur-fitur seperti fitur dasbor, fitur untuk mengelola data penghuni asrama, fitur mengelola data fasilitas asrama, fitur untuk mengatur data pengelola SIRAMA dan fitur untuk membuat laporan.

Judul: Sistem Informasi Manajemen Sarana dan Prasarana Pusat Studi Biofarmaka Tropika IPB (Trop BRC)
Abstrak: Sistem informasi manajemen sarana dan prasarana adalah sebuah sistem informasi yang bertujuan untuk mempermudah proses bisnis inventarisasi barang dan aset yang dimiliki sebuah perusahaan maupun pusat studi. Sistem informasi manajemen sarana dan prasarana Biofarmaka Tropika IPB dikembangkan karena pendataan dan pengiriman data inventaris atau barang yang masih manual. Hal tersebut menyulitkan pegawai unit bagian alat dan barang, administrator dan eksekutif di Trop BRC jika ingin membuat laporan maupun memonitor data barang atau inventaris yang dimiliki tiap unit di Trop BRC. Penelitian ini bertujuan untuk mengembangkan sistem informasi manajemen sarana dan prasarana di Trop BRC. Sistem informasi manajemen sarana dan prasarana (SIM-Sarpras) telah berhasil dikembangkan dengan menggunakan framework Laravel 5.5 dan design pattern MVC (model,view,controller). Pengembangan sistem ini menggunakan metode prototyping yang terbagi menjadi tiga iterasi. Pengujian pada iterasi terakhir tahapan metode prototyping menggunakan metode user acceptance test (UAT). Dari hasil UAT, SIM-Sarpras dinyatakan telah berhasil memenuhi keinginan dan kebutuhan pengguna.

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.
