ABSTRACT

In an organization, institution or government and private agencies that provide public services, requiring the issuance of an information system and effective to handle errors that often occur in the issuance process, which in fact is still the need for management to administrative correspondence particular decree.

Information System of Decree Based on Web is a system within an organization that will support decision-making processes and policies that will taken by those who carry the responsibility in accordance with the decree has been issued. By using information systems of decree based on web is expected to improve the performance of an organization to be more effective and efficient, which in turn accelerates the process of decision-making or policy.

By applied the information systems of decree based on web will be obtained the expected results as simplify and expedite the process of issuance of the decree to those entitled to receive the letter, so as to achieve energy efficiency, space and time and simplify both in making and in providing information associated with the issuance of the decree and show through the website.

 

Keywords: Information System, Decree, Web.

ABSTRACT

Citra is two-dimensional images generated from continuous two-dimensional analog images into discrete image through a process of sampling. Analog image is divided into N rows and M columns so become discrete image. Intersection between certain rows and columns called pixels (pixel).

The larger the contrast value given in the original image will make the resulted image from equalization will be brighter and vice versa. Contrast and brightness settings will affect the width of the image histogram. By using the histogram equalization function, then the resulting image will have the graphic histogram is more evenly distributed.

Keywords: Citra, Histogram, Diskrit

ABSTRACT

The number of motor vehicles used by the public is the outlook for providers of parking space. However, the conventional system of parking management is still applicable today much less provide convenience for users. Especially for users who often visit the park, such as shopping venues, office buildings, and also in government agencies. With the continued use of the parking ticket as evidence of parking of vehicles, as well as the payment is made in cash. Such parking system will result in a queue at the entrance/exit the parking lot. Therefore, we need a system that can perform automatic identification of vehicles that will use the car park. On this system, vehicles registered customers can identify the name and address of the owner, the vehicle license plate number, and the amount of the deposit that has been paid.

In this parking system used card RFID (Radio Frequency Identification) to replace the payment transactions that occurred in the parking system. RFID tech parking card customers will recognize the customer parking, and be a means of transaction costs prepaid parking system or using a credit card balance. Applications to enter and exit the parking booth will cut customer parking card balance, and to service the card list, buying can be done at the counter balance system administration parking.

 

Keywords : Parkiing, RFID (Radio Frequency Identification)

ABSTRACT

Fuzzification has been done using AVR microcontroller ATmega8535. Changes in temperature from 0°C to 100°C is used as the input variables, which are obtained from IC LM35. Then the analog voltage generated by the sensor is read by an ADC (Analog to Digital Converter) that is contained in the AVR microcontrollers. Membership functions used to create fuzzy sets are trapezoidal and triangular. To inform the result of changes in fuzzification process used LCD (Liquid Crystal Display). Input variable membership functions using three labels, namely, "LOW", "MEDIUM" and "HIGH".

The experimental results of fuzzification temperature by using Microcontroller ATmega8535 are validated with Matlab software has been successfully and get the same degree of membership value.

Keywords : Fuzzification, ATmega8535

ABSTRACT

Video steganography is one way to hide a message or confidential data in the video file that appears does not contain anything. Video steganography method used in this research is the LSB (Least Significant Bit) and HWT method (Haar Wavelet Transform). While the calculation of video quality to the original video steganography is done by calculating the value of MSE (Mean Square Error) and PSNR (Peak Signal-to-noise ratio).

The process of inserting a message on steganography requires two inputs, namely the message you want to hide a text file and insert the media in the form of AVI video files. Based on the calculation of video quality testing MSE and PSNR, shows the quality of the video steganography method HWT higher than the LSB method.


Keywords:  Steganoraphy, Video, Least Significant Bit (LSB), Haar Wavelet Transform (HWT)
