in front of an audience, whether in the form of speeches, presentations, lectures, or discussions. Public speaking is a crucial skill in various aspects of life, ranging from education to the professional world. This ability not only helps in academic presentations but also impacts how a person communicates and influences others. At the high school level and equivalent, students begin preparing for the next stage in their education or entering the workforce. Many challenges arise for students when speaking in front of an audience in a formal setting and explaining their presentations. Students face difficulties due to a lack of self-confidence, nervousness, panic, and a lack of mastery over the material they will present. In addition to a lack of self-confidence, other challenges include limited vocabulary, low communication skills, fear of judgment from others, and insufficient preparation. Basic public speaking training at Al Ma'shum High School in Kisaran would be highly beneficial for students to boost their self-confidence, enhance their communication skills, sharpen their critical and logical thinking abilities, and equip them for entering the workforce. The basic public speaking training will involve methods such as self-introduction exercises, role-playing, speech structure practice, impromptu speaking, expression training, intonation and articulation exercises, as well as feedback and evaluation.

ital era. Some of the problems identified include low interest in reading, difficulty in simple arithmetic operations, and lack of clarity in the library. Therefore, students have developed several programs to improve digital literacy and numeracy in schools. Recommended programs such as reading fluency, coloring pages, math puzzles, bullying education, library organization, and literacy corners will help students improve their literacy and digital skills. Interactive and varied learning methods aim to increase student interest and participation in the learning process. Apart from that, the use of technology is also an important part of increasing digital literacy and numeracy. Through training, workshops, development of digital educational content, and integration of digital and computing skills into the curriculum, we aim to enable students to develop skills that meet the needs of our time. Through these programs, it is hoped that students will improve their literacy and numeracy skills, help them handle digital information better and prepare them to face the challenges of this digital era. We hope that the results of this Teaching Campus program can provide great benefits for education and the development of students' skills at school.

lationship between the consumption of sugar-sweetened beverages and the incidence of overweight among adolescents at SMP Negeri 28 Surabaya. This study employed an analytical observational design with a cross-sectional approach. A total of 164 respondents were selected using proportional random sampling. Data on sugar-sweetened beverage consumption were collected using a Food Frequency Questionnaire (FFQ), while nutritional status was assessed using Body Mass Index-for-Age (BMI-for-Age). Data were analyzed using the Chi-square test. The results showed a significant association between the consumption of sweetened tea (p = 0.023) and carbonated soft drinks (p = 0.000) with overweight, whereas the consumption of coffee, bubble tea, sweetened milk, isotonic drinks, syrup, and yogurt was not significantly associated with overweight (p > 0.05). It can be concluded that frequent consumption of sweetened tea and carbonated soft drinks is associated with an increased risk of overweight among adolescents. Therefore, nutrition education and limiting the consumption of sugar-sweetened beverages are recommended as preventive strategies to reduce overweight among adolescents.

mmunity navigates its religious identity within a deeply rooted Torajan cultural landscape. Through ethnographic methods, including participant observation and in-depth interviews, this research explores how minority Muslims practice their faith, access public space, and maintain communal harmony. The findings reveal that religious freedom in Rantepao is negotiated through a balance of cultural assimilation and religious preservation. While formal rights are generally respected, subtle social boundaries exist, particularly regarding religious expression and ritual intersections with traditional Torajan customs (Aluk To Dolo). This study highlights the resilience of the Muslim minority and demonstrates how local cultural mechanisms facilitate daily coexistence, offering crucial insights into religious tolerance and minority-majority relations in contemporary Indonesia.
