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 performance of an algorithm can be improved by using a parallel computing programming approach. In this study, the performance of bubble sort algorithm on various computer specifications has been applied. Experimental results have shown that parallel computing programming can save significant time performance by 61%-65% compared to serial computing programming.

Abstract

Today's rapid technological developments make information increasingly important. Not just its content, but the channels or media used for information distribution also need to be secured. Information security is an important aspect that requires serious attention. One of the most important parts of information security is implementation of encryption using certain methods or techniques. This study proposes bit-based cube rotation to secure a plaintext. The aim is to produce a ciphertext that satisfies the two properties of cryptography through diffusion to produce confusion. The result shows that in a normal sentence, there is a significant change in the ciphertext which has the highest avalanche effect value of 55.47% and a correlation coefficient of 0.115. This result proves that the bit-based cube rotation can produce a good ciphertext, where the encryption result is not influenced by its original text.
