Abstract

Security is an important aspect in digital data transmission, and steganography is one way for hiding a secret message in such a way so that others are not aware of the existence of something in the message. In this research, we built a digital steganography system using web-based with Adaptive Minimum - Error Least Significant Bit Replacement (AMELSBR) method. The media to hide the message is on the form of .jpg, the output is on the form of .png, and the message is on the form of .txt. The procedures for applying AMELSBR method are Capacity Evaluation, Minimum - Error Replacement and Error Diffusion. The result shows that the AMELSBR method is able to manage for hiding and restoring files without causing excessive distortion (noise) in stego image. The AMELSBR method has a possibility of returning most files to image manipulation such as the change of image Brightness and Contrast with the black color dominant (rgb(0,0,0)), white color dominant (rgb(255,255,255)).

Abstract

In this research, we develop The Application of Encoding and Decoding Tree Using The Dandelion Code.  It aims to obtain Dandelion code of a tree using encoding and decoding. The encoding generates code from a tree, and decoding processes a code back into a tree. This application is developed to produce the best tree representation. Additionally, in this research we give an example of problem that can use Dandelion Code for solving the lowest cost for electricity installation.Keywords : Application, Encoding, Dandelion Code, Decoding, Tree, Tree Representation.

Abstract

Security and confidentiality of data transmission are two important aspects in the era of openness to data access and information. One way to secure the data transmission is using steganography. In this research, the method used is End Of File (EOF) and used image as the medium. The message is hidden by inserting it in the end of the line image file. The media for hiding the message is in the form of .jpg and the output is in the form of .png. Inputting message is done manually. Testing have  been conducted on 5 types of images with different resolutions with a number of different messages characters which are 10, 100, and 1000 characters. The results show that the method of End Of File (EOF) successfully used to hide message in the media image and to take back the message that has been inserted. The image size and the number of characters used affects the processing time for embedding and extracting. Cropping, contrasting, and brightness on stego image are conducted to analyze the resilience of the message inserted. The results show that the stego image manipulations are sensitive or resistant to the manipulation that makes the message becomes corrupted and are not recommended in manipulating stego image.Keywords : embed, End Of File (EOF), extract, image, steganography, stego Image

Abstract

This study developed a Decision Support System (DSS) by utilizing Analytical Hierarchy Process (AHP) Method as a process in selection of employees acquisition. This selection process used several criteria (multicriteria) to choose which applicants will be accepted. This Decision Support System (DSS) helps managers of Human Resources (HR) in deciding which applicants will be selected. In this application, there are criteria used and the weight of those criteria. This application of module business process will be able to generate the rank of each applicant based on the final amount. The applicant who has the greatest value will be given a better rank and it means that the applicant has criteria in accordance with company’s requirement. In addition, Web Service as a business process of payroll modules. In this process, a set of functions or methods which contained on a server can exchange data and information using an operating system and application that different from each other through the internet that uses XML as the format of message delivery. This system constructed by using PHP and MySQL as language. The result of functional testing data based on test case testing shows that the system can work "in accordance" with its analysis.

Abstract

Job Record is the reference of Worker Performance Appraisal process where maximum or not the performance worker on certain period will be determined. The Development of Job record and worker performance appraisal information system with apply XML web service as method to exchange information between one and the other domains. With Web Service into information system could be handle business process that is recruitment, job record, worker performance appraisal, and payroll system. The resulting of exchange the information that is information of  employees, overtime, and incentive. The implemented of this information system using  PHP  programming language and  MySQL database and web service method using XML programming language. The result of Black Box testing showed that this The development of Job record and worker  performance appraisal information system has been successfully created as the users need.

Abstract

Every educational institution of Vocational High School periodically carries out the admission of new students. With the existence of Decision Support System is expected to assist schools in selecting new students. There are various methods in constructing a DSS and one of them is the method of AHP. AHP is one of DSS method that can handle the multi criteria selection. By using the result of DSS with AHP method as sample data and find the biggest criteria factor in a selection. The result of this study indicates that AHP method can be implemented in information system of new students admission and it can help to make decisions in the placement of departments based on the ability of students and the selected department.Keywords: Analytical Hierarchy Process (AHP), Decision Support System (DSS)

Abstract

Nowadays the development of information technology is growing rapidly not even be stopped. Such as the communication problems, which recently seemed there is no distance anymore, everything feels close, it is all because of technology. Along with the development of science and technology, emerging technology development is a GPS (Global Positioning System). In this study, researchers design and build android-based application to find out public transport route in Bandar Lampung called Balam Trans utilizing GIS technology in it. This application allows you to search route of the city transportation (Angkot) and Bus Rapid Transit (BRT) in the city of Bandar Lampung, so users no longer have difficulty in finding public transport to get to their destination location, especially for migrants in the city of Bandar Lampung. Additionally, this application can display information about public transportation and BRT route so as to broaden the users knowledge. This application was developed using Dijkstra's Algorithm for finding the shortest route. The conclusion of this study is the application Balam Trans successfully constructed and useful for every user who has used this Balam Trans applications, proved by questionnaire application testing achieves good. Keywords : Balam Trans, Public Transportation, Angkot, BRT, Route, Dijkstra's algorithm, Play Store, Android, Smartphone, Bandar Lampung.
