An earthquake occurs when energy is suddenly released within the earth’s layers, potentially causing loss of life and environmental damage. One factor contributing to the high impact of earthquakes is the lack of student understanding and inadequate education on disaster preparedness. This study aimed to assess earthquake disaster management education at the Nur Adia Junior High School Education Foundation, Tanjung Selamat, Deli Serdang. A quantitative pre-experimental design with a one-group pretest and posttest was applied, involving 63 eighth-grade students. 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.

Stunting is a health issue that remains a concern for the government, particularly in supporting the achievement of the Sustainable Development Goals (SDGs), namely the nutritional status of children under five. Stunting, or chronic malnutrition, causes children to fail to grow, which is influenced by mothers' knowledge of nutritional fulfillment in children, especially from the first 1,000 days of birth until the child is 2 years old. The purpose of this study was to determine the effect of health education on parents in preventing stunting in Sumeith Pasinaro Village. The targets of this study were pregnant and breastfeeding mothers and parents who had children aged 1-5 years. This study used a One Group Pre-test-Post-test design with paired sample t-test analysis. There were 12 participants in the activity. Data were collected through a multiple-choice questionnaire administered before and after the socialization with the material “Prevent Stunting from the Heart.” The average pre-test score of the participants was 6.75 and then increased to 9.33 on the post-test, with a difference of 2.58. The paired sample t-test results showed a Sig. (2-tailed) value of 0.014 (< 0.05), indicating a significant increase in participants' knowledge after receiving education. Therefore, health education through socialization activities is effective in increasing mothers' knowledge about stunting prevention. Activities like this are important to continue as an effort to reduce the incidence of stunting in the community.

Air pollution is not an unfamiliar phenomenon for areas surrounding industries. The Cikoneng area has a wok industry center where the production process produces air pollution fumes. The wok industry center is adjacent to residential houses so that the factory smoke produced has an impact on the health of the surrounding community. Therefore, the targets of counseling are community leaders, health cadres, youth organizations, and residents who live around the industrial area. The purpose of this empowerment activity is to increase community knowledge, awareness, and creativity towards planting Sansevieria plants with the kokedama technique to maintain environmental health around the wok industry. The material was given using the lecture method with the help of power point media and leaflets. While the practice of planting Sansevieria with kokedama technique uses lecture and simulation methods. The Wilcoxon test was used to measure the level of knowledge of participants from the pre-test and post-test results which could show a difference in results before and after providing material with asymp. Sig (2-tailed) of 0.002, it can be concluded that there is an increase in knowledge in participants who take part in counseling activities. It is hoped that the people of Jetak Hamlet can minimize air pollution generated from the wok industry process by planting Sansevieria plants.
