E-Leges: Sistem Legalisir Ijazah Berbasis Online Pada Fakultas Tarbiyah dan Keguruan UIN Ar-Raniry
Get PDFPrinted documents such as diplomas and transcripts are very easy to do by imitating the form and content of the document. Such fraudulent practices are often passed from the monitoring of the authorities, this is because the agency's diploma checking system still uses manual methods. FTK UINAR, where the legalized certification checking system still uses manual way, so it is possible for irresponsible people to cheat such as forgery of diploma. Based on the problem, required an alternative system that can provide solutions to the problem. The system is a web based system and provide a computerized legalization service. Quick Response (QR) code will be used to facilitate verification of authenticity of the diploma for the institution of diploma user. The development methods that use in this research is prototype method. The result of the research is in the form of online legal certification system system by utilizing QR Code as the service system of alumni for legalizing diploma and transcript, which consists of database design and system design using Unified Modeling Language (UML), as well as the design of the legalized system based diploma online.Keywords: The legalized, Quick Response (QR) Code, Unified Modeling Language (UML), prototype method
Aplikasi Pembelajaran Unified Modeling Language Berbasis Computer Assisted Instruction
Get PDFUnified Modeling Language (UML) is one of the important materials in the analysis and design of information systems. UML is used in designing or modeling the system. UML has some form of diagram that is grouped in several aspects based on a different view. Forms of the diagram are illustrated by different functions and notations. This makes UML difficult to understand considering that time in the classroom is very limited. Therefore, it is necessary to design a learning aid based Computer Assisted Instruction (CAI). Interactive application interface helps students understand the learning materials. Students can learn independently wherever and whenever they need. The results of this study can be utilized for the development of teaching materials, especially about modeling the system with UML.

Data Hiding Through Media Audio
Get PDFAudio watermarking can use with various ways. Firstly, it have used for proving of ownership, production of information, copyright information in a form of a watermark, and it have routed directly in the recording. Specific owners have different insertion information. It can also be used for controlling access, watermark becomes a trigger to play music. Keeping track of unauthorized copies is a very important application. Personal information have inserted into the music. It used as numbers for customers to discover music
Penerapan Cloud Computing Pada Sistem Reservasi Homestay Dieng Berbasis Web
Get PDFHomestay is one of the places needed as lodging facilities in the tourist area. In recent years, lodging business is greatly increasing. Business lodging in Dieng is one of the promising venture business' due to the increasing number of the tourists who interested to visit the tourist places in Dieng and they need the hotel services. However, there are some managers who are unable to promote their lodging through the internet. Therefore, this research will make a software as a service in a cloud computing, regarding the Homestay Reservation System service in order to make the managers able to promote their homestay to public through the internet and it will make customers able to make a reservation through the software. This software was made by following waterfall paradigm in software engineering, start from analysis, design, implementation and testing. Testing result showed that the application deserved to be used.Keywords: information, cloud computing, homestay, reservatio
Rancang Bangun Sistem Informasi Akademik Berbasis Web ( studi kasus: SMA Swasta Harapan I Medan )
Get PDFSubmission of academic information to students, parents / guardians conducted at private high school SMA Harapan I Medan are still very ineffective and efficient both in terms of delivery time and in terms of finance. This is because the academic delivery is still manual in oral, written or via phone or SMS one by one. The impact of the process is the slow process of delivering academic information and the amount of expenditure in the delivery of information. To overcome these problems, then the academic community wants to improve the delivery of academic information systems using computerized technology. The purpose of the change is by building a School of Academic Information System (SISFO) Web-based SCRUM model. The system is built to produce academic information such as value and achievement of students in web-based schools that can be utilized by the academic staff to make it easier in conveying academic information to students, parents / guardians. This system includes and through several aspects of functionality, reliability, efficiency, and usability. And the scrum model used in the design of this system has a framework for building, developing and managing an ever-changing product. Keywords: Information , Academic, Scrum Model, We
Pengenalan Multi Wajah Berdasarkan Klasifikasi Kohonen SOM Dioptimalkan dengan Algoritma Discriminant Analysis PCA
Get PDFFace recognition is a process of identification with the image has variations changeable can be recognized, needs a method of optimization to minimize computational time by not affecting the classification results. This research proposes a face recognition system are directly based on Kohonen SOM classification that optimized by the method of Discriminant Analysis based Principal Component Analysis (PCA). Evaluation of PCA’s extraction performance uses two approaches, first the LDA method to optimize PCA issues of the election of irrelevant features of the dataset and the second approach is to apply a kernel function on the LDA (KDA), the results of both approaches are applied on face image classification for Kohonen directly. The testing is two phases, the first stage is testing with a single image of a face and then multi face. Based on the results of testing one face image, both of the approached feature extraction that proposed is very accurately be applied to the classification of the Kohonen SOM with the accurate value of the second approach PCA-KDA is more accurate with 94.22% and the first approach 93.91%, however on the first approach is faster than the second approach with the accurate value of time 0.4 seconds for PCA-LDA and 0.5 seconds to PCA-KDA to one image of the face, but while testing of multi face more two images the result is not significant.

The Development of Agent Information for Intrusion Detection
Get PDFAs the challenges and problems surround intrusion rises rapidly, the intrusion detection system has been gradually developed. Agent-based approach for intrusion detection system has developed from single to multi agent, and later developed mobile agents in order to increase system's capability to face with a more complex challenge and change. A number of studies had been identified that mobile agent can reduce network traffic, however the study related to intrusion detection using static and mobile agent for finding intruder has not been fully achieved.Keywords: Information, Intrusion, mobile, network
Kombinasi RSA-CRT dengan Random LSB untuk Keamanan Data di Kanwil Kementerian Agama Prov. Sumatera Utara
Get PDFIn this study the authors use Cryptographic Algorithms Rivest Shamir Adleman Chinese Remainder Theorem (RSA-CRT) and steganography technique Random Least Significant Bits (LSB). RSA-CRT is basically the same as usual, but utilizing RSA CRT theorem to shorten the bit size decryption exponent d by hiding d on congruent systems that accelerate time decryption, the difference in the key generation process and the decryption process. Cryptographic algorithm RSA-CRT produce ciphertext stored into a picture (image) using Steganography technique Random Least Significant Bits (LSB). The workings of Random LSB is storing the message (ciphertext) in the first bit or the second bit random key for use random number generator Pseudo Random Number Generator (PRNG) with Linear Congruential Generator (LCG) method. Ciphertext stored in a picture (image) has extracted key re-use random number generator at the time of inserting the message. Then the ciphertext is decrypted back by the algorithm RSA-CRT to produce the original text (plaintext). Merging Cryptographic Algorithm RSA-CRT with Steganography Technique Simple LSB than with Random LSB generate higher PSNR and MSE is lower, which means better level of data security and more resistant to attack. Has more difficult to find a secret message by cryptanalysis and steganalyst
