Abstract

Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.

Abstract

Along with the development of current technology, making technology is very important in today's life. Security level digital data has become more vulnerable to exploitation, the problem arises when an information technology device was attacked by people who do not want to take a responsible and important data illegally, so the administrator must act quickly to secure important data. Making a data security technology on the internet is very important information. Limitations administrator underlying the creation of a system that is able to detect and defense systems against such attacks is automation, so that it can be applied to data security. The system is built to prevent attacks on computer networks with more specific on THC - Hydra. This system will analyze the number of errors in the log into the database, and if the error exceeds the tolerance rules are made by the administrator. If the error is more than 3 times in one minute, then with automation, the system will create a rule that can imprison users who do not have such access, and access to the prison in the illegal user can not perform such activities on legal access and access to activities conducted illegal user can be recorded on a file and jail.txt. So under any circumstances and not in supervising administrator, the security of other user data will be safe and can not be retrieved or viewed by a user of illegal access.

Abstract

So far, there are coaches who are less precise in determining the ideal position of the player as it only relies on instinct and the ego of the players so that there is still a coach who has not been able to objectively assess the players.By utilizing the method of Genetic Algorithm as Decision Support System (DSS) in the process of determining the ideal position of a player who uses several criteria (multicriteria) to choose a proper player. DSS is helping coach in making the right decisions and Genetic Algorithm is used as a model for multicriteria weighting in the selection process. This application was built with tools Borland Delphi (7.0) as the user interface design and media processing PostgreSQL as its database.            Based on these results we can conclude that this application expected to assist the coaches in the decision making process and can change the appraisal of which are subjective to more objective, to determine the ideal position for a player, can determine the best position of each position of a number of players and the expected results of the Genetic Algorithm on the system constructed in accordance with the results of manual calculations.

Abstract

The increase o f request brings large traffic to networks especially to data centers, large enterprises and portal websites. In addition, server provides more and more information by using applications. Most servers have to provide all-day services, and any service interruption or key data loss in communication will result in business loss. All these require high performance and high reliability on application services. However, the increase of server processing speed and memory access speed is greatly lower than that o f the network bandwidth and applications. In addition, the increase o f network bandwidth makes server resource consumption more serious. Therefore, the servers become the network bottleneck, and the traditional single device mode becomes the network failure point. Load balancing (LB) comes to provide a good solution by providing multiple servers form a server cluster, with each server providing the same or similar services. A load balancing application is managed at the front end o f the server cluster to distribute user requests in the server cluster according to pre-configured load balancing rules, provide services, and maintain the servers. Load balancing bring good advantage such as bring faster application, low cost, the available resources will not be wasted, and no high-end devices are needed for the new resources. It is expandability. When services are increasing, the system can satisfy the needs by adding servers, without affecting the existing services and reducing service quality. Load balancing also has high reliability. When a server fails, the LB application or LB device redistributes user requests to other servers in the same cluster, ensuring uninterrupted services.

Abstract

Defense system against interference when the activity is generally done manually by the administrator. This resulted in the integrity of the system depends on the availability and speed of the administrator in response to disturbance. In the current era of information technology, almost all information is important for an institution can be accessed by its users. Disclosure of such access raises new security issues in part of a computer network system that is very important to maintain the validity and integrity of data and ensure availability of services for its users.In this issue then designed a system to detect any interference. The detection is based filtering on the port service, using the programming language Delphi 7. The data obtained from the filtered traffic data packets passing the proxy server. By building a system that can work automatically and in real time, then perform the detection of intruders or illegal activities which will then be reported to the administrator.With this administrator can find out the use of illegal ports through port filter techniques on the traffic data service in and out in real time, from both internal and external networks. Administrators can do the monitoring without having to depend on availability. With such a system administrator can perform tasks more efficiently in maintaining the validity and integrity of data.

Abstract

Wi-Fi waves are commonly used as an intermediary in the communication relationships in the wireless network. However, the use o f Wi-Fi waves can be used in addition to getting the relationship in the network, the user is also able to detect and identify other devices by using Wi-Fi waves. Ad-hoc network is a network that can be built independently by the computer with the Microsoft Windows operating system, to enable ad-hoc device has to have an identity that is SSID, the SSID is then activate the device can be detected by other devices. Activation is done ad-hoc by the netsh command is a shell command in the Windows 7 operating system. An ID must be unique for each device as there is no dual identity, to maximize the identification process. Utilizing MAC address as an identity is used, allowing the device to be uniquely identified. In addition to the MAC address is added to the device profile in the identity o f the device for easier identification. Sapa application users can identify the device is detected, and recognize it as a co-owned devices. Scheme which is the concept o f the algorithm Sapa.
