Abstract

Maintaining the security of messages is a very important thing both within an organization and the personal especially in the age of information technology today. In order to the sent message does not fall into the one’s hands who are not interested, then encryption should be created to maintain the confidentiality of a message remains secure. Classical cryptography method using Vigenère Cipher and RSA (Riverst Shamir Adleman) is one of securing methods which will be used. In this case, the initial process is doing encryption on Vigenère cipher that produces a temporary ciphertext. The temporary ciphertext will be a plaintext on the RSA algorithm and then encrypted again to produce the actual ciphertext. Merging these two methods produces a ciphertext that is more powerful and difficult to solve.

Abstract

Baseline characteristics of students’ knowledge in the concept of learning technology is required. One is the student's learning style characteristics including attitudes, cognitive and psychomotor or skills. Then, characteristics of learning styles based approach sensory preferences, including visually, auditory, and kinesthetic or learning by doing/movement and touch. In this study, methods of teaching as a learning process consisting of multimedia-based teaching, lectures, demonstrations, problem solving, discussion, exercises (drill), case studies, frequently asked questions, and experiment. Three types of questionnaire consisting of the distribution characteristics of student learning styles, the tendency of students learning methods, and the tendency of lecturers teaching methods have been implemented. In order to determine the grade level of each questionnaire with grade visual (V), auditory (A), kinesthetic (K), auditory-kinesthetic (AK), and visual-auditory (VA) have been exploited. The results showed that the relationship between these three variables has yielded a value of 68.2%. It means that the FIS method could be used in order to assess the performance relationship.

Abstract

The successful accomplishment of a divestiture is generally calculated by the dimension of accomplishment in realizing the elemental strategic goal that the company set out to achieve when adopting a divestment strategy. The paper will highlight the substantial role that IT has to fulfil in bringing company divestment to completion by investigating if any one of the existing IT Governance frameworks and standards could be implemented or adopted to serve as a managerial and governance framework towards company divestment. The IT department has a fundamental function to fulfill in the disentanglement of systems and IT infrastructure. In order to achieve this goal it is imperative to have a well-defined IT governance framework to guide the disentanglement processes and ensure the smooth execution of the IT divestment process.

Abstract

This paper outlines and presents the development of genetic algorithms (GA) that are used for analyzing and predicting Regional Economic Growth (REG) with an agriculture share (SA) and an industry share (SI) as independent variables covers 13 districts/cities in East Kalimantan Province of 2002-2012 datasets. The genetic algorithm (GA) was used for modeling of REG datasets. The results of experiment shows that GA was produced prediction value of 92.389. This results indicate that the average price fluctuation is decreased in 2012. Meanwhile, the southern region is significantly increased in 2013. The results indicated that GA was good algorithm for prediction of REG. This paper is concluded by recommending some future works that can be applied in order to improve the prediction accuracy.
