Anemia among adolescent girls is one of the health problems that is often overlooked, even though it has serious impacts on learning concentration, productivity, and reproductive health in the future. One of the main causes of anemia is iron deficiency and an unbalanced diet. This community service activity aims to increase adolescent girls’ knowledge about anemia prevention through health promotion using poster media with the approach of “Smart Nutrition for Iron Health.” The activity was carried out at Pesantren Al-Mubarak 12 November 2025, targeting 34 adolescent girls. The method included planning, preparation, implementation, and evaluation stages, with pre-test and post-test conducted to assess participants’ knowledge levels. The results showed a significant increase in adolescents’ knowledge regarding anemia prevention. Before the activity, 55% of respondents had poor knowledge, 35% moderate, and only 10% good. After the intervention, 75% of respondents had good knowledge and 25% moderate, with no respondents in the poor category. These results indicate that poster media is effective in increasing adolescents’ understanding of anemia and the importance of consuming a balanced diet rich in iron as an effort to prevent anemia among adolescent girls.

The incidence of degenerative diseases, which are part of Non-Communicable Diseases (NCDs), remains a major cause of death worldwide and in many regions of Indonesia. Meanwhile, efforts to prevent degenerative diseases affecting the adolescent age group are still rare, such as the establishment of a Youth Posyandu, including in Sungai Duren Village. There is no health post that provides youth care services in Sungai Duren Village, while there are many teenagers living there (students under 21 years old) with various lifestyles that are at risk of degenerative diseases. This study aims to analyze the increase in adolescent knowledge about CERDIK between before and after the establishment of the Youth Posyandu in order to prevent degenerative diseases early. This study is a quasi-experimental study involving 30 adolescents by measuring the dependent variable of knowledge. The research instrument used is a questionnaire. Computerized data processing and analysis were conducted through descriptive statistical analysis and T-test analysis. The results showed a significant difference in respondents' knowledge of CERDIK before and after the establishment of the Youth Posyandu in Sungai Duren Village (p=0.000). This study indicates that structured health education can improve adolescents' understanding of CERDIK and can be used as an effective promotive and preventive strategy.

Smoking behavior among adolescents is a serious and growing public health problem. Data from the 2023 Indonesian Health Survey (SKI) shows that 7.4% of adolescents aged 10–18 years smoke. This literature review aims to determine the determinants of smoking behavior among adolescents based on the Health Belief Model (HBM) theory, with a focus on components such as perceived vulnerability, perceived seriousness, perceived benefits, perceived barriers, cues to action, and self-efficacy. Using a literature review approach, this study identified and analyzed several academic references such as journals, books, encyclopedias, and others that discuss topics related to the determinants that influence smoking behavior among adolescents based on the Health Belief Model (HBM). The analysis conducted indicates that there is a relationship between perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived self-efficacy, cues to action, and smoking behavior among adolescents. The conclusion of this study shows that in 9 studies that applied the Health Belief Model (HBM) theory in examining smoking behavior in adolescents, all major components of HBM were proven to have a significant relationship with this behavior. This study provides an important theoretical basis for the development of effective and sustainable health promotion programs in controlling smoking behavior among adolescents.

Balance disorders are among the most common functional problems experienced by older adults and significantly increase the risk of falls, disability, and reduced quality of life. Early screening and health promotion efforts are essential in preventing these complications. This community service program aimed to introduce and implement the Fukuda Stepping Test as a simple, low-cost, and effective method for promotive and preventive assessment of balance impairment among elderly individuals in the community. The activity involved health education on balance maintenance, demonstration of the test procedure, and direct assessment of participants, followed by individualized feedback and recommendations for balance exercises. The results showed that the Fukuda Stepping Test was well-received, easy to perform, and successfully identified elderly individuals with potential vestibular asymmetry or dynamic balance deficits. Furthermore, the program increased participants’ awareness regarding fall prevention and encouraged adoption of regular balance training. This initiative highlights the importance of accessible physiotherapy-based screening tools in community settings and underscores the role of physiotherapists in promoting healthy aging and reducing fall risk among older adults.

Infancy is a crucial golden period for determining the quality of a child's future growth and development. Infant massage has long been recognized for its numerous benefits for infant growth and development. Various studies have shown that infant massage can increase weight gain, improve sleep quality, strengthen the immune system, and aid digestion. Many parents still lack understanding of infant massage. Some assume that infant massage is only performed on sick babies and is performed by traditional healers or medical personnel skilled in infant massage. The purpose of this community service is to increase mothers' knowledge about infant massage through outreach. The target audience was 22 mothers with babies in Gampong Barat, Nisam District, North Aceh Regency. The implementation method used was lectures, discussions, and demonstrations. The results showed that the majority of mothers' knowledge was in the good category after the outreach. This was due to the mothers' enthusiasm in participating in the outreach. Outreach is an effective method for increasing knowledge. Mothers are expected to continue to improve their knowledge about infant massage by increasing their interest in seeking information, whether through reading books, the media, or other sources.

Social media has become an integral part of adolescents' lives, offering quick access to information, including reproductive health information. However, exposure to inaccurate information can pose risks. This study aims to analyze the relationship between social media use and adolescent reproductive health knowledge and behavior. A quantitative research method with a cross-sectional approach and chi-square test was used to examine the relationship between the independent variable (social media use) and the dependent variable (reproductive health knowledge and behavior). The study population was all 10th grade students (23 students) and 11th grade students (30 students) at SMK Tamansiswa Boja Kendal. A sample of 53 respondents was taken using an accidental sampling technique, consisting of students who happened to be present and willing to participate during the study. The results showed that the majority of respondents (56.6%) had low social media usage intensity. The majority of respondents also had a high level of knowledge (75.5%) about reproductive health, with an average score of 8.13 and a median of 10. Most respondents (66.0%) demonstrated positive reproductive health behavior. However, the chi-square test results showed no significant relationship between social media use and levels of knowledge (p = 0.673) or reproductive health behavior (p = 0.495). Although social media did not show a significant direct relationship to adolescent reproductive health knowledge and behavior in the context of this study, the high levels of knowledge and positive behaviors found indicate that existing educational programs, both in schools and from other sources, have been effective. Further research with larger samples and wider geographic variation is needed to understand other factors that influence adolescent health behavior.

Hand Washing with Soap (CTPS) is a hygienic behavior that plays an important role in preventing the spread of infectious diseases, especially in children. However, in reality, this behavior is still not optimally implemented by elementary school students. One approach that can be used to increase awareness and hygienic behavior is through health promotion media that is interesting and appropriate for the child's age, such as comic media. This study aims to determine the influence of comics as a health promotion medium on improving knowledge, attitudes, and actions of CTPS in students at SD Negeri 149 Palembang. This study applied a pre-experimental design with a one group pretest-posttest design approach involving 90 students of class V. Data were collected through questionnaires to measure knowledge and attitudes and observation sheets to assess actions. Data analysis was carried out using the Paired Sample T-Test to determine the differences before and after the intervention. The results showed a significant increase in the three variables, namely the average knowledge score increased from 3.38 to 5.34, attitude from 20.37 to 30.80, and action from 37.22 to 67.21 after being given comic media. Statistical tests showed a p-value of < 0.001 on all variables, which means there was a significant effect after the intervention. Based on these results, it can be concluded that the use of comic media as a health promotion tool has proven to be effective in increasing knowledge, forming positive attitudes, and encouraging better CTPS actions in elementary school students. This study recommends the use of educational and fun visual media as part of health promotion strategies in the school environment.

The application of proper cough etiquette is an essential part of Clean and Healthy Living Behavior (PHBS) and serves as a preventive measure in reducing the transmission of respiratory infectious diseases from an early age. Health education for young children is crucial, as this stage represents the formative period where foundational habits are developed, potentially influencing long-term individual and environmental health. This community service activity was conducted on May 9, 2025, at Stella Maris Kindergarten in Tangerang City, involving 29 Nursery group children. The main objective of the program was to enhance the knowledge and skills of early childhood students in practicing correct cough etiquette and to instill healthy behaviors that they can apply in their daily lives at home and school. The implementation of the activity followed the POAC approach (Planning, Organizing, Actuating, Controlling) in a structured manner. Activities included storytelling (using engaging illustrations), screening of age-appropriate educational videos, practical simulations of cough etiquette, and fun, interactive games. These methods were designed to encourage active participation and ensure that children could understand and retain the health messages through enjoyable learning experiences. The results showed a notable improvement in the children's understanding and active involvement in practicing healthy coughing techniques, such as covering their mouths with a tissue or the inside of their elbows when coughing. Visual education combined with hands-on practice proved to be highly effective in conveying health messages to young children. The teachers responded positively to the program, emphasizing that the approach used was appropriate and should be widely implemented in other early childhood education institutions. They recognized it as a valuable promotive effort and a long-term health investment for children, laying the groundwork for healthier habits and environments in the future.

Indonesia, as an agricultural country, has a large population working in the agricultural sector. Agricultural activities often involve the use of chemicals that can cause skin disorders, one of which is contact dermatitis. Contact dermatitis is an occupational disease with a high prevalence, both globally and nationally. As a form of concern for the increasing number of dermatitis cases among farmers, a community service activity was conducted in Mlati Village, Grobogan Regency. This activity aimed to increase farmers' awareness and knowledge regarding contact dermatitis prevention. The intervention included educational sessions, interactive discussions, role-plays, pre- and post-tests, and the distribution of skin health information leaflets. The activity was carried out by the Health Promotion Team from the Faculty of Medicine, Semarang State University. The evaluation results showed an increase in participants' understanding of the symptoms of contact dermatitis by 11.86% of the 21 participants who attended. Materials considered important by participants included the importance of maintaining personal hygiene after contact with chemicals, as well as the use of personal protective equipment (PPE) during work. The participants' enthusiasm was also evident in their active participation in the discussion sessions and hands-on practice. However, there was still a lack of in-depth understanding of skin health care. This demonstrates the need for regular follow-up education to reinforce the program's positive impact. Overall, these activities demonstrate the critical importance of community-based health promotion in reducing the risk of occupational skin diseases and encouraging healthier and safer behavior changes in farmers.

Handwashing with soap (HWWS) is one of the simplest, most effective, and cost-efficient behaviors for preventing infectious diseases. However, its practice remains suboptimal at the household level in Indonesia. This research aims to analyze HWWS behavior using community questionnaire data as a basis for developing health promotion strategies through the Problem Solving Cycle (PSC) approach. This descriptive quantitative study was conducted among 50 respondents using a closed-ended questionnaire covering the knowledge, attitude, and practice dimensions of HWWS. The results showed that although respondents had high awareness and positive attitudes toward HWWS, their practices remained inconsistent due to habitual and infrastructural barriers. These findings highlight the need for integrated interventions combining direct education, social media campaigns, and improved access to handwashing facilities. This study contributes to evidence-based, participatory, and contextually adapted health promotion strategies aimed at achieving sustainable behavioral change.

Social media has proven to be an effective tool for health promotion, particularly in rapidly and widely disseminating information and encouraging behavioral changes. This study is a literature review aiming to evaluate the role of social media in digital-based health promotion interventions over the past five years (2019–2024). Articles were collected from Google Scholar, PubMed, and Garuda databases, focusing on interventions conducted in Indonesia or those with global relevance. The review of nine articles revealed that platforms like Instagram, WhatsApp, and Facebook are effective in improving health knowledge and behaviors, especially among adolescents and mothers. Strategies involving visual and interactive content, along with collaborations with digital influencers, significantly increased audience engagement. However, key challenges identified include low digital literacy, the spread of invalid information, and a lack of standardized evaluation for intervention effectiveness. This study recommends enhancing healthcare professionals' capacity in utilizing social media and strengthening public digital literacy to support sustainable health promotion efforts.

Mental health issues among adolescents have become an increasingly critical concern, particularly regarding the low level of mental health literacy among the younger generation. This study aims to analyze the role of Instagram as a health promotion medium in improving mental health literacy among adolescents aged 15–18 years. A descriptive quantitative method was employed using the Mental Health Literacy Questionnaire (MHLQ), which was distributed online to 70 respondents who met the inclusion criteria. The results indicate a significant positive correlation between the frequency of interaction with mental health promotion content on Instagram and adolescents' mental health literacy levels (ρ = 0.449; p < 0.05). Most respondents demonstrated moderate to high levels of mental health literacy, suggesting that Instagram has the potential to be an effective tool for enhancing adolescents' understanding and awareness of mental health issues. This study provides evidence that social media can serve as a non-formal intervention tool to support efforts in increasing mental health literacy among Indonesian adolescents.
