Abstract

Message security is must be managed seriously. Therefore, to maintain the confidentiality of any message, cryptography is needed. Cryptography is a science that uses mathematics to encrypt and decrypt messages. Cryptography is used as a tool to protect messages, for example, national secrets and strategies.  The method of this research is qualitative research with a literature review. This research implements a hybrid cryptographic algorithm by combining Hill cipher and 3x3x3 Rubik's cube methods with Python software simulation.

Abstract

The purpose of this study is to connect the concept of stress formulas in everyday life as a reinforcement of character education in students. This study uses a qualitative approach in the form of descriptive theoretical data with library study techniques. This study also uses the POE2WE model (Prediction, Observation, Explanation, Elaboration, Write, Evaluation). As a method of learning to strengthen character education, it places more emphasis on elaboration to strengthen the character education of student. The results of this study indicate that the concept of stress in physics can be used as a reinforcement of character education for students.

Abstract

This research was motivated by the low problem-solving abilities of students on sound wave material and the need for more innovative approaches in physics learning. To address this issue, the GISTEM learning model (Guided Inquiry, Science, Technology, Engineering, and Mathematics) was implemented. The research used a quasi-experimental method with a Pretest-Posttest Control Group Design. The population consisted of 216 students from six class XI Phase F physics specialization classes at SMAN 13 Garut. The sample was selected using a Cluster Random Sampling technique, with class XI-12 as the experimental group and class XI-11 as the control group, each consisting of 36 students. Problem-solving skills were measured using 10 descriptive test items administered as pretest and posttest. Data analysis involved prerequisite tests (normality and homogeneity), t-test hypothesis testing, and calculation of learning gains. The hypothesis test using the t-test at a significance level of α = 0.05 showed that  (15.56 > 1.67). Therefore, Hₐ was accepted, and H₀ was rejected. These results indicate that the GISTEM learning model significantly affects students’ problem-solving skills on sound wave material. The effectiveness of this model is attributed to its ability to promote independent learning, support conceptual understanding, and encourage the application of knowledge in new contexts.

Abstract

The PKK of Nglele Village plays an important role in supporting family development and welfare through various work programs. In implementing these programs, PKK cadres are required to be able to manage administration, compile activity reports, and create accountability reports (LPJ) independently. The main problem faced by PKK cadres of Nglele Village is limited skills in operating Microsoft Word and Excel, so that the creation of accountability reports (LPJ) and administrative documents still depends on external parties. The Microsoft Office (Word and Excel) training program for PKK cadres of Nglele Village aims to: (1) Equip PKK cadres with basic Microsoft Word skills for document and report preparation. (2) Train PKK cadres in the use of Microsoft Excel for data processing and administrative recording. (3) Encourage PKK cadres' independence in compiling accountability reports (LPJ) without relying on external parties. Increase the effectiveness and efficiency of PKK cadres' work in carrying out organizational administration. The method applied in this training is a Hands-on Training-based Workshop combined with a Service Learning (SL) approach. Service Learning is a learning approach that integrates theory with real-world practice in the community. The conclusion of this community service activity is that it can increase the independence of PKK cadres, eliminating their reliance on external parties for administrative document management. This activity supports the capacity building of PKK cadres and empowers the Nglele Village community in the digital era, resulting in more structured, efficient, and professional work.

Abstract

Technological developments in the 21st century era, especially in the field of education, are increasingly important and change the way teachers view learning. One thing that supports the learning process is the use of digital-based learning media, including Google Site. Research on the development of physics teaching materials based on the POE2WE model with the help of the Google site with the aim of: 1) Developing physics teaching materials based on the POE2WE learning model with the help of the Google site; and 2) analyze teacher and student responses to physics teaching materials based on the POE2WE learning model assisted by Google Site. The research was carried out at Madrasah Aliyah Negeri 1 (MAN 1) Tidore Islands. The research data was obtained from validation results from several validators, namely material, language and media validators used to state the suitability of teaching materials, while teacher and student responses were obtained through the results of filling out questionnaires. The data obtained from the research results showed that on average the teaching materials developed were declared very suitable for use by class XII students at MAN 1 Tidore Islands, especially regarding electromagnetic induction material. The feasibility of the teaching materials developed is 88.25%. Analysis of teacher response data obtained a result of 95.33% and for student responses a result of 96% was obtained. It can be concluded that the physics teaching materials based on the POE2WE model assisted by the Google site received a response in the category of strongly agreeing to be used.

Abstract

The family plays a central role in shaping the pattern of Islamic religious education habituation in early childhood, as the family environment is the first place where a child receives education. Instilling religious values from an early age becomes a crucial foundation in building strong Islamic character. This study aims to examine the role of the family, especially parents, in implementing patterns of Islamic religious education habituation in early childhood. The research method used is descriptive qualitative with a literature study and empirical observation approach. The results show that the family acts as the primary role model through daily behavior, communication, and religious practices, such as encouraging children to pray, read the Qur'an, and learn supplications. This habituation pattern requires consistency and positive reinforcement so that religious values can be deeply instilled. In conclusion, the family's role is vital in shaping a child's religious personality, which will serve as their provision for facing future life challenges.
