Judul: Automatisasi perintah suara sebagai kendali formasi pada permainan futsal menggunakan codebook
Abstrak: Game development today is very advanced. Game Industry has been developing games in terms of graphics, storyline, and artificial intelligence. Artificial intelligence existing in current games development are getting smarter. The problem is, most game consoles are still using controllers such as joystick, keyboards and the other tools. In this research, has been developed a futsal game as artificial intelligence simulation, has been developed a futsal game as artificial intelligence simulation, by implementing some steering behaviors and finite state machine for modeling their movement. This futsal game controlled by voice command for the formation transition. The artificial intelligence of this futsal games are implemented using object oriented programming language. They consist of 4 steering behaviors and 7 field player states for their movement and 4 goal keeper states. Voice command are implemented using mel frequency cepstrum coefficients (MFCC) as feature extraction and modeling codebook as pattern recognition. The best frames for voice command system is 125 and 256 with value of K is 32. The accuracy of integration of two system (artificial intelligence system and voice command system) is testing of frame 128 for offence formation is 92,75% and for defence formation is 73%. Testing of frame 256 for offence formation is 93% and for defence formation is 73,5%

Judul: Modeling Multi-Agent in Futsal Sport Using Finite State Machine.
Abstrak: Building agents for futsal scenario requires methodologies for implementing high-level complex behavior and efficient programming. With that hypothesis in mind, this paper will show that we can develop futsal agents using simple logic and rule-based manner with Finite State Machine (FSM). FSM provides a powerful way to describe dynamic behavior of systems and components. The systems adapt specific behaviors with the main focus on how agents should behave for current situation. This research is designed with State design pattern to implement FSM in object oriented languages. In order to describe procedural aspects of the agents behavior, the state machine represented by state diagram. Because of this, we can revise behavior of agents which is triggered by external events. From this research the system can describe agent’s behavior and specified the state of the current situation. Keywords: Multi-agent, Finite State Machine, object oriented, State design pattern.

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).
