This article explores mathematical logic as a fundamental discipline within mathematics that systematically investigates the principles of valid, coherent, and consistent reasoning. Mathematical logic serves as an essential foundation for developing structured thinking and constructing well-grounded, persuasive arguments supported by clear justification. It primarily focuses on the processes of reasoning, argumentation, and formal proof, enabling individuals to distinguish between valid and invalid conclusions. By establishing precise rules and logical structures, mathematical logic provides a rigorous framework for assessing the strength and consistency of arguments. The discipline emphasizes clarity, objectivity, and analytical accuracy in examining propositions and their relationships. In practice, mathematical logic is presented through the use of symbolic representations, formal logical statements, connectives, quantifiers, and truth tables to analyze patterns of reasoning and verify the truth values of statements. These systematic tools allow complex ideas to be evaluated methodically, prevent logical fallacies, and ensure that conclusions are derived from sound and demonstrable reasoning principles.

Data were collected through questionnaires to measure students’ knowledge before and after the educational intervention on earthquake disaster management. The results indicated that before the education, 69.8% of students rarely received information about earthquake causes, 61.9% had never participated in school earthquake evacuation simulations, and 55.5% had never practiced evacuation drills. After the educational intervention, knowledge improved, with 66.6% of students reporting that the program significantly increased their understanding of earthquakes. Statistical analysis showed a significant difference between pretest and posttest scores (Sig. 2-tailed = 0.000 < 0.05), confirming the effectiveness of the intervention. The study concluded that education on earthquake disaster management can enhance students’ knowledge and preparedness. It is recommended that schools implement regular educational programs and disaster simulation exercises to cultivate students’ readiness and promote a culture of disaster preparedness within the school environment.

The goal of this thesis is to increase awareness and give victims a better understanding of the causes of bullying and coping mechanisms by analysing the causes, effects, and efficacy of current anti-bullying interventions at Cendekia Harapan School in Jimbaran, Bali. To strengthen anti-bullying initiatives, it also assesses current solutions and makes culturally appropriate suggestions. Students completed open-ended surveys as part of a qualitative research design to learn more about their individual experiences, opinions, and the success of ongoing programs. To find patterns in bullying behaviours and their impacts, thematic analysis was used. The results showed that bullying is frequently caused by insecurity, a desire for power, and a need to fit in. Bullying victims often experience emotional distress, mental health conditions like anxiety and depression, and academic decline. According to the study, bullying can be influenced by the school environment. While students believe that current initiatives are effective, they also recommend additional interventions like workshops that foster empathy and greater parental involvement. These findings provide useful recommendations for improving school-based anti-bullying initiatives and corroborate theories put forth by Olweus and Adler.
