One of the encryption algorithms is the Hill Cipher. The square key matrix in the Hill Cipher method must have an inverse modulo. The unimodular matrix is one of the few matrices that must have an inverse. A unimodular matrix can be utilized as a key in the encryption process. This research aims to demonstrate that there is another approach to protect text message data. Symmetric cryptography is the sort of encryption utilized. A Bernoulli Map is used to create a unimodular matrix. To begin, the researchers use an identity matrix to generate a unimodular matrix. The Bernoulli Map series of real values in (0,1) is translated to integers between 0 and 255. The numbers are then inserted into the unimodular matrix's top triangular entries. To acquire the full matrix as the key, the researchers utilize Elementary Row Operations. The data is then encrypted using modulo matrix multiplication.

One of the most widely used methods of survival analysis is Cox proportional hazard regression. It is a semiparametric regression used to investigate the effects of a number of variables on the dependent variable based on survival time. Using the Cox proportional hazard regression method, this study aims to estimate the factors that influence the survival of patients with type 2 diabetes mellitus. The estimated parameter values, as well as the Cox Regression equation model, were also investigated. A total of 1293 diabetic patients with type 2 diabetes were studied, with data taken from medical records at PKU Muhammadiyah Hospital in Yogyakarta, Indonesia. These variables have regression coefficients of 1.36, 1.59, -0.63, 0.11, and 0.51, respectively. Furthermore, the results showed the hazard ratio for female patients was 1.16 times male patients. Patients on insulin treatment had a 4.92-fold higher risk of death than those on other therapy profiles. Patients with normal blood sugar levels (GDS 140 mg/dl) had a 1.12 times higher risk of death than those with other blood glucose levels. Type 2 diabetes mellitus is a challenge for many Indonesians, in addition to being a deadly condition that was initially difficult to diagnose. As a result, patient survival analysis is needed to reduce the patient's risk of death.

This study aims to explore the development of research related to parental satisfaction with faith-based schools and to build a predictive model for future interest trends using bibliometric and supervised learning approaches. The bibliometric analysis was conducted using the VOSviewer software on 402 articles indexed in Scopus, focusing on co-authorship, keyword co-occurrence, and publication trends from 2010 to 2023. In parallel, a survey was conducted among parents (n=120) to assess key predictors of satisfaction using a supervised classification model. The bibliometric findings indicate that research on faith-based education has grown steadily, with clusters of themes emphasizing parental engagement, religious values, and school choice. The predictive model shows that parental satisfaction is significantly influenced by perceived moral development, academic quality, and alignment with family beliefs. The supervised algorithm achieved an accuracy of 86%, confirming the reliability of the predictive variables. This dual approach offers novel insights into the intellectual landscape of faith-based schooling and practical tools for anticipating parental preferences. The findings have implications for educational institutions and policymakers in designing responsive strategies to maintain trust and competitiveness in faith-based education.

Students' low reading interest greatly affects learning outcomes in Vector Analysis class. This is due to the rare interaction between students and learning resources in class. To increase student activity in reading and understanding the concept of vector analysis material, an e-LKM product is needed. This study aims to develop Student Worksheets (LKM) in electronic form that is integrated with numeracy literacy which can be used for learning vector analysis courses by knowing the validity and practicality of procedures so that the use of these e-LKM can improve students' critical thinking. This development research uses the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Furthermore, the evaluation stage is carried out at each stage to improve the e-LKM that is made. The subjects were 21 students in semester VI of class C Mathematics Education FKIP Universitas Ahmad Dahlan.

The majority of vocational mathematics teachers in Lumajang region provide mathematics materials traditionally using textbooks as learning resources. Whereas the fast development of technology can support the improvement of teachers' Technological Pedagogical Content Knowledge (TPACK). The use of technology such as Canva and Mathcitymap applications makes teaching materials look better, real, and more attractive. It was necessary to improve teachers' soft skills in mastering the Canva and Mathcitymap applications so that their skills in integrating technology in mathematics learning materials also increased. The implementation of this project uses training and mentoring methods for service partners, namely members of the MGMP of vocational mathematics teachers of Lumajang Regency in the odd semester of 2023/2024. Training was conducted online through zoom meetings and mentoring was carried out directly to selected teachers to practice the use of Canva and Mathcitymap. The results of the program showed an increase in mastery the concept of "Canva as an interactive math learning media" at 84.7%, an increase in mastery of the concept of "Mathcitymap" as a learning support application at 80.3%, and an increase in teachers' TPACK in making digital math learning media at 84%. This high increase in skills and knowledge needs to be balanced with the availability of digital facilities and infrastructure at school, which is the main obstacle faced by teachers at this time. In addition, teachers also expect further training on digital-based assessment in differentiated learning. References Adawiyah, R., Amin, S. M., Ibrahim, M., & Hartatik, S. (2021).

The focus of education during the COVID-19 pandemic is more likely to be cognitive and learning. There has been no maximum effort in strengthening character education. The limited face-to-face meetings in learning have an impact on character education. This situation also applies at the university level. Prospective mathematics teachers who are currently studying have an essential role in building good character education. This study will see how future mathematics teachers' character in producing culture-based learning videos will be seen. The theme in the video that was made was ethnomathematics. The subjects in this study were prospective mathematics teachers who had implemented campus teaching programs and educational internships. With the teaching experience that is owned, it will be seen how the character of the prospective teacher during making learning videos and what character values are contained in the tape so that it can have a positive impact on students. Based on observations during the manufacturing process, most of the prospective teachers have central character values . The results of ethnomathematics-based learning videos are one of the media that can instil character values for students.

Some conjectures related to the radical theory of rings are still open. Hence, the research on the radical theory of rings is still being investigated by some prominent authors. On the other hand, some results on the radical theory of rings can be implemented in another branch or structure. In radical theory, it is interesting to bring some radical classes into graded versions. In this chance, we implement a qualitative method to conduct the research to bring the Brown-McCoy radical class to the restricted graded Brown-McCoy radical class as research objective. We start from some known facts on the Brown-McCoy radical class and furthermore, let G be a group, we explain the Brown-McCoy radical restricted with respect to the group G. The result of this paper, we describe the Brown-McCoy radical in restricted graded version and it is denoted by G^G. Furthermore, we also give the fact by explaining G^G (A)=(〖G(A))〗_G, for any ring A, as the final outcome of this paper.
