Modifikasi Algoritma Vigenere Cipher dengan Pembangkit Kunci Random Number Generator Dalam Pengamanan Citra Digital

Digital image is an image that can be processed by a computer. Digital images that are not allowed to be known by others or are said to be private and are not allowed to be manipulated by other irresponsible parties. The act of manipulating, hijacking or tapping the image will cause harm to the owner of the image. The technique to reduce these actions is to use cryptographic techniques. Cryptographic techniques are very well known for securing information with a password that only the owner of the image understands. To strengthen the results of the encryption carried out by the Vigenere Cipher Algorithm, modifications are made to the Random Number Generator. The Random Number Generator used is Linear Congruent Generator which has linear recursive properties combined with modulus. So the combination of vigenere cipher with random number generator Linear Congruent Generator is very difficult for other parties to abuse the image

Pengaruh Model Pembelajaran Inkuiri Terbimbing terhadap Keaktifan Belajar Siswa di Sekolah Dasar

The activeness of students in teaching and learning activities undergoes various things, including the learning model used by teachers when teaching. The learning model uses the inquiry learning model where its process involves the activeness of students in teaching and learning activities to create critical thinking that is one of logical thinking way focused on decision-making to overcome the problem. In the guided inquiry, the student role is more dominant and active whereas the teacher directs and guides the right way. The problem that will be explained is how it affects the guided inquiry learning model on the activeness of 5th-grade students in SD Negeri Pujorahayu. The research method uses a quasi-experimental design whereas design research uses nonequivalent control group design. This research analyzes 2 classes that are 5th grade of A and B. The result of this research uses a simple linear regression test that the significant value was 0,000 ≤ 0,05 so Ha is accepted and Ho is declined which meant a significant affect between variable of the guided inquiry learning model on the activeness of 5th grade students in SD Negeri Pujorahayu. Explained the percentage of effect of puberty variable (X) on the student learning activeness (Y) is R square of 0,603 meaning that independent effect (guided inquiry learning model) on dependent variable (learning activeness) of 60%. So, guided inquiry learning model effects of 60% on the student learning activeness.

The Development of an Android Application of Terms Register in Malay – English for KSSM Physics and Its Usability among Student Teachers

This research aims to develop an Android application of terms register in Malay – English for KSSM Physics for Physics student teachers’ use. A need analysis was performed to obtain feedback from ten student teachers about the existence of this application. This application is developed based on the ADDIE instructional model and undergoes a pilot test using a qualitative approach to obtain the initial feedback. After improvement, this application undergoes an application validity process through three experts using face and content validity forms. A quantitative approach was made using the Heuristic Evaluation Questionnaire (HEQ) survey on 30 student teachers to obtain the application usability. This research has produced an application on an Android platform containing 418 extracted terms from Standard Document for Curriculum and Assessment (DSKP) for Form 4 and Form 5 Physics with the application name is FiPhyNeo. FiPhyNeo receives a Content Validity Index (CVI) of 0.93. FiPhyNeo also has obtained high usability (mean = 4.37 ± 0.34). This research developed an Android application called FiPhyNeo containing terms register in Malay – English for KSSM Physics for student teachers that is valid with high usability. This research will benefit the student teachers, current teachers, and students for a fast and easy search of terms register and operates in offline mode to support the teaching and learning of Physics.
The Need and Effectiveness of Form Two Algebraic Expression Training Module

The aims of the study are to determine the need and effectiveness of Algebraic Expression Training Module (Mi-T2) in improving Form Two students’ higher order thinking skills. The level of thinking skill of Malaysian students is still low. A descriptive study and quasi-experimental study was conducted at a secondary school in Perak in order to determine the need and effectiveness of Mi-T2 module. Questionnaires about the need of Mi-T2 training module, pre-test and post-test were the instruments being used in the study. The school teacher provided responses by completing questionnaires to determine the need of module. A control group and experimental group were selected from the Form Two classes to be the sample study. They had to answer the instruments pre-test and post-test before and after the treatment. The findings showed that 80% mathematics teachers indicated that there is a need for the Mi-T2 training module. The comparison of the mean scores for the experimental group and control group showed that there was a significant improvement in the post-test result, but the increase of the mean score for the experimental group was higher which from 50.87% to 78.27%. In conclusion, the study shows that there is a need of Mi-T2 training module and the training module can help the students to master the topic of algebraic more effectively. It is in the hope that Mi-T2 training module can be used extensively to help more students in mastering the concept of algebra more effectively and improving their thinking skill.
