Judul: Pengembangan Aplikasi Android Modul Kartu Rencana Studi (KRS) pada Sistem Informasi Akademik Institut Pertanian Bogor (SIMAK IPB).
Abstrak: Modul KRS pada SIMAK IPB merupakan suatu sistem yang digunakan oleh mahasiswa IPB untuk mengisi KRS untuk kegiatan akademik serta mengakses informasi akademik. Modul KRS SIMAK IPB yang tersedia saat ini adalah berbentuk website dan dapat diakses melalui http://simak.ipb.ac.id. Untuk memudahkan pengaksesan modul KRS SIMAK IPB, diperlukan pengembangan pada perangkat mobile. Pada penelitian ini dikembangkan aplikasi mobile untuk modul KRS SIMAK IPB berbasis Android. Metode penelitian dan pengembangan yang dilakukan pada penelitian ini adalah menggunakan model incremental dengan jumlah iterasi sebanyak 3. Pengembangan front-end aplikasi menggunakan Android Studio dengan bahasa pemrograman Java dan pengembangan back-end aplikasi menggunakan Visual Studio 2015 dengan bahasa pemrograman C#. Seluruh fitur sistem telah diuji dengan metode black-box dan sudah berjalan dengan baik. Fitur yang telah berhasil dikembangkan tersebut antara lain pengisian KRS, pengecekan jadwal, rekapitulasi studi, jadwal departemen, pemilihan minor, ringkasan data mahasiswa dan grafik pergerakan IP dan IPK, serta biodata.

Judul: SIMAK Ilkom untuk Memantau Tugas Akhir Mahasiswa Berbasis Android
Abstrak: Currently, the Department of Computer Science has been adopting the web-based academic administration system (SIMAK) to monitor the students’ final project. The purpose of SIMAK is to facilitate the communication between supervisor and student in completing the final project as well as recording the supervising process and the literatures used. To add the functionality of SIMAK, this research developed Android-based SIMAK application. The application was developed using Java and XML programming languages, as well as the clientserver system with SMS gateway. The research showed that SMS gateway can be applied on Android-based SIMAK.

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).
