Security aspects are the most important thing for the time being, since there are many higher crime rate and thus require innovation in overseeing inhabited places and to create a sence of security. Making security applications to monitor the incidence of theft or negative things such as criminal acts by those strangers which generally occurs in a room. Having the ability to monitor the condition of a room through the PIR sensor (Passive Infrared Receiver) and recorded by the camera as a webcam which can turn on the buzzer alarm. In this study, we described how the system will respond to any movement and it will be detected then inform and visualization an images and a buzzer as an alarm call that indicates a person who entered the room. And there is a camera view so the webcam can see a real incident. The equipment that has been designed and implemented this will certainly be very helpful in terms of improving security with the concept of real time and video recorder that can be run as the evidence at the police when a time there was a criminal act. Security application software design is done by using waterfall method and implementation analysis using the SWOT method is used to view a topic or problems from four different sides. Results of analysis is a referral or recommendation to retain strength and adds to the advantage of existing opportunities, accompanied by decresing shortages and avaid Threats.Keywords : Application Security, Webcam, PIR, arduino

Bantumi or so-called Mancala or Congklak, is a traditional game which belong to the type of strategy game that is played by two players. Along with the development of technology, particularly in smartphones, then made this Bantumi traditional game to make it more practical to play is by expanding into the Android mobile-based application form. With the help of Artificial Intelligence (AI), the computer will be able to play and think to beat his opponent as well as humans. Alpha-Beta Pruning Algorithm is the best step search algorithm used in this Bantumi application in determining the best move. By using this algorithm, the computer will do a search with the best possible move. The higher the depth of the search, the better the computer will determine the pace of the game so that the computer will be more difficult to defeat. That's needed for a high concentration of the players in the play, in order to train and improve the skills of logic that is in them.Keywords: bantumi, alpha-beta pruning, algorithms, android

Develop a study group at school is conducted manually and take a long times to compile the result. Moreover, the review of the group is done many times; therefore, it takes along times. Based for this reason it needs an automatic study group system. Genetic algoritm is an alternative in solving the problem, which serves as the brain to organize the study group. How to represent the problem into a chromosome is the primary key of this algorithm. Chromosome encoding process is using integer permutation. Chromosome length is determined by the number of students (male and female). The number of genes determined from the depth of static single snake formation (SSF depth). The method used is the elitism which used half of the population with the lowest fitness value and then will be eliminated. Cross over operator used is a single crossing point, by choosing the initial locus and subsequent locul will be exchanged with each other. By using the original data for each existing study program, this application will not has trouble in developing study group and of course has a far better performance compare to manual preparation of the study group.Keywords : Genetic algorithms, study group
