Abstract

The more commercial flights now, will be result more the number of aircraft operated and the competition to become the airline can keep operating even more difficult. Some airline companies can not compete with other companies, has gone out of business. This is one of them caused by the inaccuracy of an airline's decision in the selection of aircraft types. Type of aircraft used for flight routes should be tailored to the needs so that it can provide benefits to the company. The selection of planes is determined based on market analysis with indicators of the number of passengers, aircraft, engineering aspects of the commercial aspects or the operational costs of aircraft and competitor analysis. Aircraft direct operating costs are costs directly related to the operator of the aircraft in flight routes. Direct operating cost is very influential in the selection of aircraft types that will be used. On certain conditions the determination of the decision must be taken quickly, in which one of the conditions is the availability of relevant information. Information is the output system that can be utilized by the parties in need. Decision support system to determine the type of aircraft is a computer application that provides output in the form of aircraft operating cost information that can support managers in making decisions determining the effective fleet at the new flight routes.

Abstract

Decision Support System or DSS is a system that helps managers in solving the problems of semi-structured. Many techniques are used to make the Decision Support System, one with Fuzzy Logic. Fuzzy logic is one of problem-solving techniques where the degree of membership which are typically represented by values 0 and 1, with Fuzzy Logic is the degree of membership can be represented with a value between 0 and 1 so that it can be more balanced.             KPPN Yogyakarta in determining an employee on leave not yet have an application, and is still done manually. Therefore, to further assist in making the determination of the employee on leave should be made DSS. DSS will use fuzzy logic techniques MADM applying TOPSIS method in the calculation process. SPK expected this may be an alternative in the determination of an employee on leave in KPPN Yogyakarta later. Decision Support System determination of an employee on leave with TOPSIS method is to obtain results that are not much different from the calculations manually, so it can be applied to support the decision in the determination of employee leave.

Abstract

Funding accumulation should be designed to attract people to save in the institution money islamic. Savings Islamic investment is to apply the system to yield a return on investment. The value of customer revenue will never be the same each month even though they are the same a mount. Therefore, we need an alternative form of information storage decisions to be based recommendations for the specific results. For the results calculated by the method of the average daily balance is multiplied by other factors such as per classification average balance bank of funds, and the ratio(%). The average balance is the accumulation of sediment balance is divided by the number of days in a month. The application of fuzzy inference systems Tsukamoto and madman will be compared to the recommended savings will be applied to the system. Fuzzy logic has a degree of  membership that represented the values 0 and 1, to be more balanced in the calculation is limited by certain factors. Factors include the amount of sediment balance and sediment balance your time to calculate the value of savings products or recommendations.Application of fuzzy Tsukamoto and  Mamdani gives an overview of the differences indetermining the final outcome of the process defuzzifikasi, so that the known method is more suitable for recommending the value of deposits with a limited output of certain values (lower and upper limit of deposits). Fuzzy calculations have been tested with analysis of mathematical calculations manually and generate the same value.ListenRead phonetically

Abstract

Development of the world's information and communication technology-based growing rapidly. The development of these technologies has given rise to another dimension in human life, namely the need for computer use. Application of machine vision applications where a computer has the ability to understand the data in the form of image and make decisions based on data obtained from a real object, in this case is generated through the capture image from webcam.            The images (digital images) of a real object through a webcam can be done in many ways capture the object. In this research object retrieval using an object of activity is captured on the webcam through the motions of objects. Digital image acquisition is performed with the tool in the form of software (Obtion Remote Version 1.0). Obtion (Object Detection) method works with the system of comparison between that time frame the previous frame captured by the camera at the time of recording the object. Comparison of the difference in the frame will be accommodated in a place that will be used to support the execution of an object by counting the number of pixels that exceed the value of the difference in number of field values with regulator frame to frame changes in the location of the object motionObtion Remote Version 1.0 will take a digital image of the object with trigger object motion detection performed. Digital image acquisition (capture the object with a webcam) will be done automatically if the object has been successfully detected. The detected object will be stored automatically in the directory are executed as a digital image storage.

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

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.
