OPTIMALISASI PENYUSUTAN EXIF METADATA DENGAN TEKNIK SUBSTITUSI NULL VALUE PADA KASUS KEAMANAN CITRA DIGITAL Hendro Wijayanto; Iwan Ady Prabowo; Paulus Harsadi

Data and information security technique is a way to keep an object confidential. eXchangable Image File Format (EXIF) Metadata is data information about digital image. In the digital forensic investigation, this is very useful for copyright security or safeguarding digital evidence. Steganography and cryptography techniques have been widely used to overcome these problem. However, from the research that has been done in terms of security EXIF of metadata digital image photography, there are still some weaknesses. Among them is the depreciation of the digital image size after decryption. Since the standard EXIF metadata treatmens released by JEIDA and CIPA have different characteristic with JFIF metadata. A null value will be deemed to be the content with a value of 1 in EXIF standard. While in JFIF metadata model, the value of null is considered to be worth 0 (zero). This is make the EXIF metadata security process is shrinking of -25,15% from the original size. With the optimizing null value before encryption, the same metadata will be obtained between original image and after decryption. The null value will be replaced with an empty string (it’s worth 1) before encryption. Results from the model obtained an average of -1,51% depreciation of the original digital image size.Therefore, this technique can optimize the digital image copyright protection.

This study aims to diagnose ENT (Ear Nose Throat) disease through a computer-based system. Often people do not understand about the disease, and doctors are limited in serving the community. For the expert, the expert system can be used as an inexperienced assistant. Also for substituting human knowledge in the form of the system, so it can be used by many people. This application will assist in finding a conclusion illness with appropriate prevention. The application system is analyzed data ENT diseases and symptoms of the ENT disease. The method used is the Certainty Factor. Application development using PHP and MySQL for the database. The results showed that the system is built to provide information to visitors about the type of disease and its definition, diagnose symptoms experienced visitors, danmemberikan initial solution treatment.Keyword: certainty factor, expert system, ENT disease

Penerapan Pathfinding Menggunakan Algoritma A* Pada Non Player Character (NPC) Di Game Paulus Harsadi; Sri Siswanti

In this Game , we implement a character designer at the enemy by applying the algorithm A * pathfinding Algorithm. Furthermore, A * is as the algorithm for searching solutions with the use of additional information (heuristics) in which it is an optimal solution. The purpose of developing this Adventure Game is A * Algorithm implementation for Pathfinding using Unity 3D. Pathfinding is the fastest path of searching process from point of origin to point of destination by avoiding the various barriers along the path traveled without crashing the existing barrier along the way. Its design and development applies Unity 3D. The test result of algorithm in the Game shows that the total of passed node result is 50 nodes. It is similar with the previous manual count result. Furthermore, the Game route shows that its passed path is similar with manual count.

Existence of the file documents in an agency is required by the leadership. The position of the file can be spread over several units (sections) in the agency, requiring the search process to determine the existence of the file. Search process is performed using mobile agent that is aglet. Aglet can move to form a 'slave' aglet according to its function as work aglet to search the files in the units with Branching. Designing a search system files on distributed systems using the aglet has been created to produce an analysis aglet role in the search process in a distributed system.Keywords : Search, mobile agent, aglet, distributed, branching

Academic Information Systems in STMIK Sinar Nusantara Surakarta handling processes include financial, KRS online, New Student registration. In managing the process, using several application modules that implement the concept of Enterprise Resource Planning (ERP), wherein execution of the application have not been audited to ensure alignment of IT with business objectives. To measure how far the alignment between business processes, applications, and business enterprise.Strategies for information systems auditing standards COBIT 4.1, where the calculation of which can represent the level of maturity of a company. While service quality has a major influence on academic activities, the audit focused on the user's perspective of the Balanced Scorecard. The results of this audit stated that the level of process maturity. Process which indicates that the organization has a formal standard procedures and written, in the absence of supervision to perform the procedure, allowing the occurrence of many irregularities.

The development of internet has become one of the most popular data communication media. The ease of use and complete facilities are the advantages possessed by the internet. However, along with the development of internet media and applications that use the Internet, crime on information system increases as well. With various illegal information-gathering techniques developing, many are trying to access information that is not their right. There are several security techniques for sending messages confidentially and securedly, one of which is known as steganography. This study combined steganography and cryptography. The message was encrypted first using base64 then inserted using the LSB Crossed method. This method was aimed at making the process of extracting messages by unauthorized ones not easy. Embedding message into images was using the last binary number of the RGB value of an image by randomizing the placement of binary numbers by integrating base64 coding so that it combined base64 messages which next the text messages would be encrypted. The measurement results in the stego image using PSNR (Peak Signal to Noise Ratio) showed that the image quality after the insertion process was > 50 db
