Clean and Healthy Living Behavior (PHBS) is a promotive and preventive effort aimed at improving the level of public health. The Baduy indigenous community in Leuwi Damar, Kanekes Village, Lebak Regency, Banten Province has local wisdom and traditional lifestyles that influence daily health practices. However, limited access to information and health services is a challenge in implementing PHBS optimally. This article aims to describe the implementation of PHBS education in the Baduy Leuwi Damar community and its impact on community knowledge and attitudes. The method used is a descriptive approach with educational activities through counseling, discussion and simple demonstrations adapted to local culture. Educational material includes personal hygiene, clean water management, environmental sanitation, and healthy living behavior in daily life. The results of the activity showed an increase in public understanding regarding the importance of personal and environmental hygiene, as well as the emergence of a positive attitude towards implementing PHBS without eliminating the traditional values adhered to. PHBS education carried out using a simple cultural and communication approach is considered effective in increasing the health awareness of the Baduy community. Therefore, health education programs based on local wisdom need to continue to be developed as a strategy to improve the health of indigenous communities. .(Riset Kesehatan Dasar,2019).

Self-health education plays a crucial role in shaping the healthy habits, character, and behavior of elementary school students. This learning emphasizes not only physical hygiene but also the development of social and emotional skills that can prevent negative behaviors such as bullying. This study aims to examine teachers' strategies in implementing self-health education as an effort to prevent bullying behavior in elementary schools. The method used was a literature review by analyzing various relevant scientific sources from 2020–2025. The results of the study indicate that teachers' strategies in implementing self-health education include three main approaches: habituating clean and healthy living behaviors, integrating health values ​​into learning, and fostering social-emotional development through reflective activities in the classroom. These three strategies are effective in fostering students' awareness, discipline, responsibility, and empathy towards their peers. Self-health education also contributes to creating a safe, healthy, and respectful learning environment. Thus, self-health education can be used as a preventive strategy to prevent bullying in elementary schools. Teachers act as role models and facilitators who ensure the values ​​of health, empathy, and social responsibility are integrated into teaching and learning activities.

Introduction: Clean and Healthy Living Behavior (PHBS) is an important indicator in improving health status, particularly among university students as a productive age group. Health knowledge plays a role as a predisposing factor in the formation of healthy behavior. Individuals with a good level of health knowledge tend to have higher awareness and motivation to implement PHBS. Conversely, a lack of knowledge may lead to behaviors that pose health risks. Objective: This study aimed to determine the relationship between the level of health knowledge and clean and healthy living behavior (PHBS) among students at Universitas Muhammadiyah Semarang. Methods: This study employed a quantitative design with a cross-sectional approach. The sample consisted of 55 students, including students from health-related and non-health-related faculties. Samples were selected using an accidental sampling technique, namely respondents who were encountered and willing to complete the questionnaire at the time of data collection. The research instruments were a health knowledge questionnaire and a PHBS questionnaire. Data analysis was conducted using univariate and bivariate analysis with the Spearman test. Results: The results showed that the majority of respondents had good health knowledge (89.1%) and good PHBS (90.9%). The Spearman test results showed a p-value of 0.001 (p < 0.05), indicating a significant relationship between the level of health knowledge and PHBS. Conclusion: It can be concluded that the better the level of students’ health knowledge, the better the implementation of clean and healthy living behavior.

This study aims to describe the condition of clean water access and its impact on public health in Swadaya Village. The research employed a qualitative approach through in-depth interviews with household heads, community leaders, health workers, and local water managers. The findings reveal that access to clean water in Swadaya Village remains very limited. Most residents rely on dug wells and river water for daily needs, while only a small portion use water from the local water utility (PDAM) due to high installation costs and limited pipeline coverage. The water quality often decreases during the dry season, becoming cloudy, odorous, and causing skin irritation. These conditions contribute to the increasing incidence of waterborne diseases such as skin infections, diarrhea, and typhoid fever. Besides infrastructure limitations, the lack of community awareness regarding hygiene and sanitation practices worsens the situation. Although the village government has proposed clean water development programs, their implementation has been hampered by budget constraints. The study concludes that clean water problems in Swadaya Village are not only related to resource availability but also to environmental management and community behavior. Therefore, improving water infrastructure must be accompanied by community education to promote a healthy, safe, and sustainable living environment.

Stunting remains one of the major chronic nutritional problems in Indonesia, including in Oesapa Village, Kelapa Lima District, Kupang City, East Nusa Tenggara Province.

To reduce the risk of parasitic infections and improve children’s nutritional status, preventive efforts through education and health promotion are essential.This community service activity aimed to increase public awareness and knowledge, especially among parents and caregivers of stunted children, regarding the importance of maintaining hygiene and sanitation to prevent intestinal parasitic diseases. The methods used included participatory approaches such as interactive lectures, group discussions, and practical demonstrations of clean and healthy living behavior (PHBS), food hygiene, clean water management, and household waste disposal. Evaluation was conducted using pre-test and post-test instruments to measure changes in participants’ knowledge.The activities, carried out from May to September 2025 in Oesapa Village, showed a significant improvement in community understanding of hygiene and sanitation practices. Participants demonstrated greater commitment to maintaining environmental cleanliness and adopting healthier daily behaviors. Continuous educational efforts and multisectoral support are needed to help reduce the prevalence of stunting in the region

This community service activity aims to increase awareness and independence of elementary school students in maintaining hand hygiene through education on proper handwashing. The background to this activity stems from the low level of handwashing habits among school-age children, despite hand hygiene being a simple action that has a significant impact on preventing infectious diseases. Based on initial observations at Tamanbali 3 Public Elementary School, most students did not yet have the habit of washing their hands before eating or after playing, despite the availability of facilities. Therefore, a hand hygiene education program was implemented, designed to help students understand the importance of proper handwashing according to WHO guidelines. The activity methods included outreach through educational posters and videos, demonstrations of the seven steps of handwashing, mentoring in daily habits, and evaluation of behavioral changes. The results of the activity showed a significant improvement in students' hand hygiene behavior. Students began washing their hands independently before eating and after activities without being reminded by teachers. The school environment also became cleaner and healthier due to the growing awareness of personal hygiene among students. Teachers and the school are committed to continuing this habit as part of the daily classroom routine. This activity demonstrates that hand hygiene education delivered through interactive methods can shape character and hygiene habits from an early age.

In general, school students buy snacks in the school canteen or street vendors (PKL) around the school. 2 The types of food sold are varied, ranging from healthy snacks to unhealthy snacks so that they can attract students to consume school snacks. Healthy snacks are foods that have sufficient and balanced nutrition and do not contain (contaminated) elements that can harm or damage health. This community service activity aims to educate healthy eating patterns to prevent food and drinks containing microbial contamination at Mariana Catholic High School, Medan.

 Communicable diseases remain one of the leading public health burdens in Indonesia, particularly in densely populated residential areas and communities with inadequate sanitation. Poor housing conditions including insufficient ventilation, overcrowding, excessive humidity, inadequate lighting, and improper waste and wastewater management have been shown to increase the risk of respiratory infections, diarrhea, and other environment-related diseases. This literature review aims to identify effective environmental health strategies for preventing communicable diseases by synthesizing findings from 11 scientific articles published between 2014 and 2025. The review shows that basic sanitation, indoor air quality, waste management, and the implementation of the Community-Based Total Sanitation (STBM) program are key determinants in reducing disease incidence. Additionally, successful interventions depend heavily on clean and healthy living behaviors (PHBS) and active community participation. These findings highlight the importance of a comprehensive approach that integrates physical environmental improvements, health education, and community empowerment to create healthy settlements and sustainably reduce the risk of communicable diseases.

Household waste management is a significant challenge in creating clean, healthy, and sustainable residential areas. Dependence on manual monitoring methods often leads to delays in waste collection, waste pile-ups, and operational inefficiencies. This community service program implements a Smart Trash Monitoring Sistem (STMS) based on the Internet of Things (IoT) in Graha Panyindangan Estate, Indramayu. The system utilizes ultrasonic sensors and ESP32 to detect waste levels and sends real-time data to a dashboard accessible by residents and cleaning staff. The results of implementing STMS show improved efficiency in waste management, with waste collection being carried out on time based on accurate, real-time data. This system also reduces the need for manual inspections and encourages responsible waste management behavior among residents. In addition to technical benefits, there have been social changes, such as increased environmental awareness and the formation of new social norms within the community. The involvement of local leaders in supporting the system’s sustainability further strengthens the implementation of the smart living concept, resulting in a cleaner, healthier, and more sustainable residential environment in the long term.

Dermatophytosis is a superficial fungal infection of the skin, hair, and nails that is often found in tropical climates such as Indonesia, including Jambi City, which has high humidity and community habits that can support fungal growth. This study aims to describe the demographic characteristics of dermatophytosis patients who received treatment at a private dermatologist and venereologist in Jambi City throughout 2023. This study used a descriptive design using secondary data from patient medical records. A total of 399 patients who met the inclusion criteria were analyzed univariately and the results are presented in the form of a frequency distribution table. The results showed that tinea corporis was the most common type of dermatophytosis, followed by tinea cruris and tinea capitis. The majority of patients were male, aged 17–25 years, had a high school education, and worked as students. The most common locations of lesions were on the trunk and groin. These findings suggest that the productive age group is more susceptible to dermatophytosis, possibly related to high physical activity, excessive sweating, and suboptimal personal hygiene. This research is expected to be the basis for planning health education regarding the prevention of fungal infections and improving clean and healthy living behavior in the community.
