Judul: Pengembangan Sistem Informasi Aktivitas Kemahasiswaan (Studi Kasus: Direktorat Kemahasiswaan Institut Pertanian Bogor).
Abstrak: Pengelolaan aktivitas kemahasiswaan Institut Pertanian Bogor masih dilakukan secara manual. Terutama pada proses penyimpanan data yang belum memiliki basis data yang saling terhubung dengan semua kegiatan kemahasiswaan. Kegiatan yang dimaksud antara lain organisasi kemahasiswaan, program kreativitas mahasiswa, dan prestasi mahasiswa. Penelitian ini melakukan pengembangan sistem informasi berbasis web untuk mempermudah Ditmawa Institut Pertanian Bogor dalam pengelolaan aktivitas kemahasiswaan. Sistem informasi ini dikembangkan menggunakan pendekatan prototyping dengan dua kali pengulangan sesuai kebutuhan pengguna dan berorientasi objek menggunakan ASP.NET MVC framework. Metode black-box digunakan untuk pengujian sistem yang menunjukkan seluruh fungsi pada sistem informasi aktivitas kemahasiswaan IPB berhasil dijalankan.

Judul: Pengembangan Sistem Informasi Layanan Bebas Pustaka (Studi Kasus: Perpustakaan Institut Pertanian Bogor)
Abstrak: Sistem informasi layanan bebas pustakaInstitut Pertanian Bogor saat ini sudah berjalan dengan baik. Namun,masih terdapat kendala dalam pengelolaan data karena data mahasiswa belum terintegrasi dengan basis data IPB dan masih dilakukan secara manual. Penelitian ini melakukan pengembangan sistem informasi berbasis web dengan data yang terintegrasi untuk menangani kendala tersebut.Sistem informasi ini telah berhasil dikembangkan menggunakan metode prototypingdan pendekatan berorientasi-objekdengan ASP.NET MVC framework. Metode black-box digunakan untuk pengujian sistemdan hasilnya menunjukkan seluruh fungsi pada sistem informasi layanan bebas pustakaIPB berhasil dijalankan.

Judul: Mercury Toxicity and It’s Effect on Histopathology Change of Nile Tilapia (Oreochromis niloticus).
Abstrak: Nile tilapia (Oreochromis niloticus) is one of fish species that oportunity to contaminated with mercury. The effects of pollutants can damage living organisms organs and can cause death. The effects caused mercury had acute or chronic character. The aims of this study are to determine threshold and acute toxicity of mercury chloride (HgCl2) of Nile tilapia (Oreochromis niloticus), to assess the effect of mercury chloride (HgCl2) on several biometric parameters (survival, growth rate of average daily weighted, liver condition, bile and reproductive variability of Nile tilapia (Oreochromis niloticus), assess the level of damage to the histological structure of the gills, liver and kidney of Nile tilapia (Oreochromis niloticus) caused mercury chloride (HgCl2) exposure. This study was conducted from February to June 2013. Nile Tilapia (Oreochromis niloticus) were used in this study were female with average weight 20 grams or 11-13 cm length range. Toxicant materials used in this study was mercury chloride (HgCl2). Fish were reared in each aquarium 60x40x30 containing 48 liters of water. This study consists of three stages: a preliminary test, acute test, and sub-chronic test. To determine the changes in biometric condition of tilapia approximated by measuring the survival rate (SR), the growth rate of average daily weight , the content of mercury in the fish organs, hepatosomatic index (HSI), the relative bile volume (VER), gonadal soamtic index (IKG), fecundity and oocit diameter, tissue damage caused by mercury in fish organs by making histological preparations stained with hematoxylin and eosin. The median lethal concentration (96 hr, LC50) of Mercury Chloride was calculated as 1,64 mgL--1.The survival rate was highest in the control treatment (46,67 %) . Mercury chloride with concentration 0.196 mgL--1 show significant effect to changes HSI and relative bile volume, and oocyte diameter of Nile tilapia (p < 0,05). Mercury chloride with a concentration of 0,164 mgL-1 and 0,196 mgL-1 have not a significant effect on the growth rate of weight, gonadal somatic index and fecundity of Nile tilapia (p > 0,05). Mercury chloride cause damage to gills (hyperplasia, hypertrophy, proliferation and neukrosis), liver (hyperplasia, hemorhage, shrinkage of hepatocytes, proliferation and neukrosis) and kidney (hyperplasia, hemorrhage, shrinkage of the glomerulus, proliferation and neukrosis).
