Multilevel logistic regression is one of the alternatives to solving a problem that has a nested data structure like the student data in Alauddin in 2016. The data indicates that students are nested in each different study program. This condition allows the students in the same study program tend to have similar characteristics. The study aims to gain a student graduating model of punctuality using multilevel regression analysis and recognize factors that have a significant impact on student graduating time. Based on our research, we find the best model that fits the data to be the random intercepts model with a random slope of gender variable. The variables that have significant effects are gender, cumulative achievement index, educational background, and accredited program. Keywords: logistic regression, nested, multilevel logistic regression, graduation of studentMSC2020: 62J05

This study aims to determine the implementation of the school literacy movement as a form of independent character in students at MI Muhammadiyah 4 Brangsi. Most students in Indonesia experience a lack of interest in reading. One way to overcome the lack of interest in reading is by optimizing the school literacy movement. The school literacy movement is an effort to shape the character of students. Character education is an effort to prepare a generation with a social, religious, cultured, and virtuous sense of words, deeds, behaviour, morals, and independent personality. This research method is qualitative with a descriptive approach. The research data sources are primary and secondary data with data collection techniques through observation, interviews and documentation. Data analysis used includes data reduction, data presentation and conclusion drawing. The results showed that implementing the school literacy movement fostered student's independence. The implementation of the school literacy movement in students at MI Muhammadiyah 4 Brangsi is divided into three stages, namely the habituation stage, the habituation stage, and the literacy stage. The implementation of this school literacy movement is carried out routinely every two weeks. It can be concluded that with the literacy movement, the literacy movement can instil independent character in students. In implementation, it needs to be invested in students to introduce reading habits from an early age and get used to reading for 15 minutes according to the existing schedule.

Data security is vital in digital exchange, yet standard Least Significant Bit (LSB) steganography remains vulnerable to unauthorized extraction. This study aims to develop a web-based steganography application combining LSB with Exclusive OR (XOR) encryption to enhance confidentiality. The proposed method involves encrypting secret data using XOR operations before embedding it into the cover image's LSB. The application is built on a web platform for accessibility, and the resulting image quality is evaluated using Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The results demonstrate that the system successfully embeds and extracts data intactly. The obtained PSNR values exceed 40 dB, indicating that the stego-images maintain high visual fidelity indistinguishable from the original images, thereby offering a robust solution for secure data transmission.
