This study aims to enhance students' engagement and mathematics achievement through the implementation of differentiated learning. The method employed is classroom action research conducted in two cycles, each consisting of planning, action implementation, observation, evaluation, and reflection stages. The research was carried out during the odd semester at SMK Muhammadiyah 1 Sleman with the participation of 28 students from the XI Automotive class. The findings reveal a significant improvement in students' engagement and learning outcomes. In the first cycle, the average engagement score was 9.51, which increased to 17.12 in the second cycle. Regarding learning outcomes, in the first cycle, only 10 students (35,71%) achieved the passing grade, while 18 students (64.29%) did not, with an average score of 64.75. In the second cycle, the number of students achieving the passing grade sharply increased to 28 students (100%) with an average score of 84.92. These results demonstrate that differentiated learning effectively enhances student engagement and mathematics achievement in the XI Automotive class at SMK Muhammadiyah 1 Sleman during the 2024/2025 academic year

This study aims to develop a mathematics module on the infinite limit material of algebraic functions to improve critical thinking skills of phase-F students at SMA Muhammadiyah 1 Sleman. The study used the ADDIE development model which includes five stages: Analysis, Design, Development, Implementation, and Evaluation. Data were collected through material and media expert validation questionnaires, student response questionnaires, and pretest and posttest tests. The validation results showed that the module was classified as very valid, with an average score of 71 from material experts and 103 from media experts. The student response questionnaire produced a practicality score of 72.6, indicating that the module was practical to use. The effectiveness test was carried out using the normality test and paired sample t-test using SPSS-25, which showed a significant increase (p <0.05) in student learning outcomes. The average pretest score of 58.22 increased to 84.27 in the posttest, with an n-Gain value of 0.64 which is classified as moderate. This module also improved scores on all indicators of students' critical thinking. Thus, the developed e-module is declared valid, practical, and effective in improving students' conceptual understanding and critical thinking skills

The Baitul Arqam program, held at SMA Muhammadiyah Mlati on March 19-20, 2025, aimed to strengthen Islamic identity and build the moral integrity of the participants. The program involved various educational activities, such as discussions on Muhammadiyah ideology, worship training, forums on Islamic values, and reflective activities. It focused not only on theory but also on spiritual experiences that heightened religious awareness. The program was conducted in three main stages: preparation, implementation, and evaluation. The methods used included lectures, role-playing simulations, and discussions. The results of the implementation showed success in motivating participants to delve deeper into Muhammadiyah values, with high enthusiasm throughout the event. Participants also expressed great benefits in preparing themselves to become better Muhammadiyah cadres. Evaluation was carried out using a non-test approach, encompassing cognitive, affective, and psychomotor aspects. The success of this activity highlights the importance of careful planning and good coordination in supporting the strengthening of character and religious understanding among students. This program is expected to be held regularly to prepare future generations who are more committed to the values of the organization

The primary objective of this activity was to enhance students' understanding of the critical importance of instilling and practicing the values of Pancasila as a means to confront the growing threat of radicalism in the era of globalization. This event was conducted at Muhammadiyah Seyegan Vocational School and engaged 25 twelfth-grade students in a dynamic and interactive dialogue session. The program featured a knowledgeable resource person who delivered an in-depth presentation on a specific theme, which was followed by an engaging discussion to explore and reflect upon the key points shared. The outcomes of the dialogue revealed that the values embedded within Pancasila are not only foundational but also remain highly relevant and applicable in addressing contemporary challenges. This initiative sought to provide students with a clearer understanding of Pancasila as a comprehensive national worldview, a philosophical cornerstone of Indonesia, and a guiding principle for governance and citizenship. Beyond theoretical understanding, the activity encouraged participants to internalize Pancasila's principles in their daily interactions and decisions, fostering a commitment to embody these values in their personal lives, within their families, in community settings, and in their contributions to national and state affairs. Through this approach, the program aimed to cultivate a sense of responsibility and pride in upholding Pancasila as a unifying and protective force against radicalism

This study is a Classroom Action Research (CAR) aimed at improving the understanding of multiplication concepts among Grade II A students of SD N Koroulon 2 Sleman through a Deep Learning approach assisted by coin-based media. The research was conducted in two cycles using the spiral model developed by Kemmis and McTaggart. In the Cycle I, the learning process focused on using coin games as a concrete medium to build conceptual understanding of multiplication. The results showed that only 68% of students achieved learning mastery. Discrepancies were still observed in the achievement indicators, particularly in converting repeated addition into multiplication sentences. Based on the reflection results, improvements were implemented in the Cycle II through strategies such as paired group work, varied learning activities, and the inclusion of a "semi-abstract" stage in the instructional process. The results of the second cycle showed a significant improvement: learning mastery reached 89%, and all learning achievement indicators exceeded 80%. This study demonstrates that the Deep Learning approach, supported by contextual media and adaptive teaching strategies, can meaningfully enhance students' conceptual understanding of multiplication. This success was also supported by effective classroom communication and the cultivation of reflective thinking habits throughout the learning process.

This study aims to describe the procedure for managing incoming and outgoing mail in the General and Personnel section. The type of research used is descriptive qualitative, namely the author describes the results of observations, interviews, documentation and analyzes the data obtained in the field. The author of this final project is the result of research conducted from May to June 2020. The results showed that the process of managing incoming and outgoing letters in the general and staffing section, namely incoming mail, starts from receiving letters, scheduling letters, directing letters, storing letters. While the outgoing letter starts from drafting the letter, approval of the letter concept, typing the concept, giving the coordination stamp, signing the letter, recording the letter, storing the letter. The procedure for managing letters at the education office is running optimally.
