Judul: Aplikasi Web Pencarian Rute Angkutan Umum yang Optimal di Kota Bandung
Abstrak: Angkot merupakan moda transportasi yang banyak dimanfaatkan masyarakat dalam memenuhi kebutuhan mobilitasnya sehari-hari. Kota Bandung memiliki banyak angkot dengan rute yang berbeda, karena itu sulit untuk memilih angkot bagi seseorang yang tidak mengenal rute angkot di kota Bandung. Penelitian ini bertujuan untuk membangun aplikasi web angkutan kota Bandung dengan menggunakan algoritme Dijkstra untuk pencarian rute terpendeknya. Data yang digunakan merupakan informasi umum angkot resmi yang terdaftar di DLLAJ kota Bandung. Pembuatan sistem informasi geografis ini dengan menggunakan bahasa pemrograman PHP, PgRouting dan PostgresSQL untuk merancang sistem database sebagai penyimpanan data aplikasi. Hasil dari pengembangan aplikasi web ini menampilkan rute angkot berdasarkan tempat asal dan tujuan yang dimasukkan pengguna.

Judul: Penerapan Algoritme Dijkstra Pada Rute Angkot Bogor Berbasis Android
Abstrak: There are some problems dealing with angkot in Bogor. The problems are related to the complexity of route system and amount of angkot unit. In this research, information system was developed for guiding user in order to choose the most efficient route to reach the purpose location. The Dijkstra algorithme was employed to support the system in order to find the route that provide the shortest distance from the origin to the purpose location. The system was developed by using Java and XML programming language and evaluated by applying black box testing method. The evaluation results show that the system can succesfully meet all requirements, particularly providing the most efficient route of a certain location.

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).
