Judul: Mashup Informasi pada Situs Blog Institut Pertanian Bogor Berbasis Wordpress Menggunakan Web Service
Abstrak: Wordpress merupakan salah satu content management system (CMS) untuk pengembangan aplikasi web. Situs web Institut Pertanian Bogor (IPB) memiliki subdomain bagi mahasiswa, dosen, atau lembaga kemahasiswaan untuk memiliki sebuah blog berbasiskan Wordpress. Isi dari Wordpress biasanya memiliki struktur yang sama dan isinya dapat dipanggil dalam format tertentu melalui web service yang sudah tersedia di dalamnya. Pada penelitian ini akan diintegrasikan isi dari total 20 blog Wordpress di situs IPB, yang terdiri dari lima blog mahasiswa dan lima blog lembaga kemahasiswaan, serta sepuluh blog dosen. Web service yang digunakan yaitu JSON API, sebuah API yang tersedia untuk Wordpress. JSON API mengijinkan sisi klien mendapatkan dan memanipulasi isi wordpress menggunakan HTTP request. Isi dikembalikan dalam data berstruktur JSON yang akan mengalami praproses sehingga dapat diindeks oleh Sphinx Search, sebuah library tambahan untuk membangun sebuah sistem pencari. Hasil evaluasi sistem pencari yang didapatkan yaitu nilai mean average precision dari 9 query yang diuji sebesar 0.48, yang berarti sekitar 48% dokumen yang didapatkan oleh sistem berdasarkan query, relevan terhadap query.

Judul: Pengembangan Agregator Berita IPB
Abstrak: The rapid growth of Internet led to the diversity of the data. An example of this diversity is the sites of faculty and department at Bogor Agricultural University (IPB), which not all of newest news of the sites can be retrieved using Rich Site Summary (RSS). This would complicate the collection of recent news. To overcome this, the method that be used is mashups. The mashup was created using the Application Programming Interface (API). In this study, the API used is the Google Search API, which is will be used to search related news.

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).
