<![CDATA[Today, Collection of image data on the Internet is growing rapidly in terms of quantity. In parallel with this a method of content -based image retrieval (Content -based image retrieval) is needed in the process of identifying and accessing visual information. Content -based image retrieval basically simulates the human perception of an image so that an error occurred in the text -based retrieval methods can be overcome. In this research, the image retrieval system is implemented with the extraction of low level features of the image. Low-level information used in this study is the color information contained in the image. Composition of color pixels in an image can be represented in a color histogram. The degree of similarity between the image color is determined based on the distance between the histogram using Laplace distance and Euclidean distance. The smaller the distance between the histogram, the higher the percentage of similarity of an image. Results of image retrieval through the database will be displayed according to the query by example method performed by a user, based on the sequence of images that have a higher percentage of similarity.]]>

<![CDATA[The use of cryptographic techniques and digital signatures is widely applied as a method to secure confidentiality and authenticity of data such as sending data over the internet network. on cryptographic, data that intent to be secret is disguised by changing the original data to unreadable format while the digital signature is used to check the authenticity of the message according to the source. Both of these techniques have weaknesses, but by combining these two techniques it will make confidential data more secure in secrecy and authenticity. The main discussion of this research is to create a data security application by combining cryptographic techniques and the use of digital signatures. The algorithm used is a Multi- encryption algorithm consisting of a combination of substitution and transposition algorithms and el gamal algorithm for document verification using digital signatures. The process that is done is to encrypt the message either typed directly into the application or from the text file that is loaded into the application. The results of this study are applications designed to meet information security needs, both protection against the confidentiality of information and protection against counterfeiting and changing unwanted information.Keywords: Cryphtograph, Multi-encryption, Digital Signature]]>

<![CDATA[A university needs IT strategic planning to be able to guide the future development of the university, one of them is Atma Jaya University of Makassar. The IT Implementation at Atma Jaya University of Makassar is currently still minimal because it has not utilized information technology well and thoroughly for operational purposes. This is due to the absence of IT strategic planning for the long term. The previous research has designed IT strategic planning using the Mobile Enterprise Architecture Framework. The documentation results from IT strategic planning have some recommendations of IT projects that can be implemented. The priority selection of IT project becomes very important in achieving IT strategic planning that has been designed. This research applies Analytical Hierarchy Process and utilizing Expert Choice tools to get priority from 20 recommended IT projects that related with IT strategic planning. There are 7 criteria of IT project implementation that is obtained from Head of BAPSI UAJM. The result of this research shows that IT project which is the main priority to be implemented is the Development of Student Portal and Lecturer with the priority scale of 0.109 and the lowest priority IT project is the Procurement of LAN Cable (0.011) because the network infrastructure in UAJM is currently sufficient to support the designed IT strategic planning.Keywords: IT strategic planning, project priority, Decision Support System, Analytical Hierarchy Process]]>
