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.

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.

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.

Rapid adoption of cashless payments has reshaped everyday spending, especially among young consumers. While e-wallets deliver speed and convenience, constant exposure to discounts, cashbacks, and one-click checkouts may also foster more frequent discretionary purchases. This study examines the relationship between e-wallet usage intensity and consumptive lifestyle, focusing on how convenience and promotional stimuli relate to spending tendencies. Using a cross-sectional online survey of students and early-career workers, we collected self-reports on payment habits and consumption patterns with validated Likert-type instruments. Data were screened and analyzed with correlation and linear regression after basic assumption checks. The results indicate a positive and statistically meaningful association between e-wallet usage and consumptive lifestyle; respondents who transact more often via e-wallets tend to report stronger preferences for instant gratification, hedonic purchases, and impulse buying. Convenience features (e.g., stored cards, fast checkout) and promotional exposure (e.g., limited-time deals) emerged as salient correlates of the relationship. The findings add contextual evidence from Indonesia’s digital economy and suggest practical implications for users, platforms, and educators. Financial-wellbeing interventions such as digital budgeting tips, in-app nudges, spend limits, or post-purchase reflections may help align seamless payments with healthier consumption decisions. Future work can test causal mechanisms and evaluate design features that encourage prudent, goal-consistent spending without diminishing user experience.

This study aims to examine the application of mocaf flour as a partial or complete substitute for wheat flour in the preparation of dadar gulung, a traditional Indonesian delicacy. The research is grounded in the potential of mocaf, which is gluten-free, rich in dietary fiber, and supports efforts to diversify food sources based on local commodities. A quantitative experimental method was employed with three flour formulations 50% wheat : 50% mocaf, 25% wheat : 75% mocaf, and 100% mocaf evaluated through organoleptic testing by 25 panelists with varying levels of experience. The assessment parameters included color, aroma, taste, texture, and overall perception. The findings indicate that the formulation containing 100% achieved the highest overall score, followed by the 75% mocaf and 25% wheat blend, while the 50% mocaf and 50% wheat formulation ranked lowest. These results suggest that a dominant proportion of mocaf can maintain the sensory quality of the product, although full substitution requires further optimization to enhance consumer acceptance. This research contributes to the development of healthier innovations in traditional foods, offers a gluten-free alternative for individuals with dietary restrictions, and promotes the sustainable utilization of local resources.

Physical fitness is a fundamental determinant of athletic performance and is strongly influenced by dietary intake and lifestyle behaviors. Adequate protein consumption is essential for muscle development and energy metabolism, whereas smoking has detrimental effects on lung function and aerobic capacity. This study aimed to explore the relationship between protein intake and smoking habits with physical fitness, measured by maximal oxygen uptake, among athletes of Persela Football Academy under-eighteen. A quantitative approach with a cross-sectional design was applied, involving adolescent male athletes. Protein intake was assessed using a semi-quantitative food frequency questionnaire, smoking habits were obtained through structured interviews, and maximal oxygen uptake was measured using the multistage fitness test. Findings revealed that the average daily protein intake of athletes was relatively high, while the mean maximal oxygen uptake score fell within the good category. Correlation analysis demonstrated a significant association between protein intake and aerobic fitness, as well as between smoking habits and aerobic fitness. The results indicate that lower protein intake and higher smoking frequency are linked to reduced physical fitness capacity. This study highlights the importance of nutritional interventions and healthy lifestyle promotion as integral components in the development of youth athletes to optimize performance and prevent decline in fitness.

Premarital sexual behavior among adolescents remains a public health concern influenced by social change, technological development, and social environment. This study aims to analyze factors associated with adolescent premarital sexual behavior based on the Health Belief Model (HBM). A systematic literature review was conducted on eight studies published between 2019 and 2025, including journal articles, undergraduate theses, and a doctoral dissertation. The findings were analyzed by categorizing the results into six HBM components: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. The results indicate that perceived susceptibility is the most consistently associated component with adolescent premarital sexual behavior. Perceived severity, perceived barriers, cues to action, and self-efficacy also show significant associations in several studies, whereas perceived benefits demonstrate the weakest and most inconsistent relationship. Overall, adolescent premarital sexual behavior is shaped by the interaction between risk perception, environmental support, and individual confidence in behavioral control. These findings confirm that the Health Belief Model remains a relevant framework for designing adolescent health promotion and preventive interventions.

The use of electronic cigarettes (vapes) among adolescents continues to increase and has emerged as a significant public health concern influenced by the interaction of individual, social, and environmental factors. This study aims to comprehensively riview the factors influencing adolescent e-cigarette use from the perspective of Social Cognitive Theory. A descriptive-narrative literature review was conducted using empirical national and international studies published between 2015 and 2025 and retrieved from Google Scholar, PubMed, and ScienceDirect databases. The synthesis of the literature indicates that adolescent vaping behavior is influenced by social environmental factors, including peer influence and exposure to social media, as well as personal cognitive factors such as knowledge, risk perception, outcome expectations, and self-efficacy. These factors operate thorugh observational learning and reciprocal interactions between individuals, environment, and behavior. This review concludes that Social Cognitive Theory provides a relevant and comprehensive framework for understanding adolescent vaping behavior and offers a foundations for the development of effective health promotion interventions and preventive policies.

Health communication and community empowerment are crucial for improving health outcomes at the primary health care level. As a primary health care facility, the Empat Ulu Community Health Center in Palembang plays a strategic role in disseminating health information, strengthening community capacity, and promoting healthy lifestyles through various educational activities.

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.

Based on the analysis, it can be concluded that the right business location is an important strategy in increasing competitiveness and business revenue. Therefore, for MSMEs, selecting a location that suits the target market needs to be carefully considered so that the business can grow sustainably.

Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. It is transmitted through the air, specifically through droplets expelled by sufferers when coughing or sneezing. TB is divided into two main types: pulmonary TB, which attacks the lungs, and extrapulmonary TB, which can affect other organs such as the pleura, lymph nodes, skin, bones, and meninges. In the Community Health Center (Puskesmas) work area, 77 new cases of pulmonary TB were recorded from January to April 2025. Meanwhile, coverage of Tuberculosis Prevention Therapy (TPT) only reached 44.7%, still below the national target of at least 50%. This condition indicates the need for increased health promotion activities and community diagnostic approaches as promotive and preventive measures, in order to increase TPT coverage and reduce the incidence of TB. The results of the respondent questionnaire showed that the level of public knowledge about TB reached 64.6%, positive attitudes at 94%, and preventive behavior at 72%. Based on these findings, it is recommended that outreach activities be conducted regularly to improve public understanding, which can ultimately encourage behavioral changes and reduce TB cases.

Cervical cancer is a malignant tumor that grows in the cervix caused by infection with the Human Papilloma Virus, acquired through sexual intercourse. Indonesia ranks 8th in the highest incidence of cancer in Southeast Asia, the highest prevalence of cancer is Yogyakarta Province where Sleman Regency ranks the highest IVA positive at 2.5% and Halis IVA at the Pakem Health Center is suspected of cervical cancer reaching 13 out of 22 positive IVA results. This achievement is still very low, because there is still low public awareness to carry out early detection of cervical cancer. To determine the relationship between attitude and behavior for early detection of cervical cancer. Quantitative research with a Case Control approach. A sample of 160 women with a proportional sampling technique. Data collection was in the form of filling out questionnaires online using Google Forms with chi square test data analysis and logistic regression. There was a relationship between positive attitude p-value=0.017 and OR of 3.462, women aged >35 years p- value=0.038, multipara parity p-value=0.007, with early detection behavior of cervical cancer. Parity provided a great chance of 7,038 times that women performed early detection behaviors of cervical cancer (CT 95%= 0.187-264,350). To improve early detection examinations, health workers can design health education and promotion models, increase educational socialization to cadres, the public and the community continuously and sustainably.

Coffee is one of the most widely consumed beverages worldwide, including in Indonesia. Coffee consumption has become part of people's daily habits, whether as a companion for work, relaxation, or as part of social culture. However, this habit is often associated with the potential for increased blood pressure due to caffeine, which is a stimulant to the central nervous system and can affect the function of the heart and blood vessels. This study aims to analyze the relationship between the frequency of coffee consumption and systolic and diastolic blood pressure in adults. The research method used a quantitative approach with a correlational design. The study sample consisted of 100 adult respondents selected through a purposive sampling technique based on certain criteria, such as not currently taking antihypertensive medication and having no history of serious cardiovascular disease. Data collection was carried out in two stages. First, respondents completed a questionnaire containing information on the frequency and habits of coffee consumption, including the number of cups per day and the type of coffee consumed. Second, blood pressure was measured using a digital sphygmomanometer to obtain accurate systolic and diastolic blood pressure data. The results of the statistical analysis showed a significant positive correlation between the frequency of coffee consumption and increases in blood pressure, both systolic and diastolic. Specifically, respondents who consumed more than two cups of coffee per day tended to have higher blood pressure values compared to those who consumed one cup or less. This finding has important implications for health promotion efforts, particularly in educating the public about wise coffee consumption. Recommendations include limiting coffee intake, choosing coffee with low caffeine content, and balancing this with a healthy diet, regular physical activity, and stress management as part of a healthy lifestyle.

Obesity among college students is a public health issue that is gaining increasing attention because it is associated with an increased risk of chronic diseases such as diabetes mellitus, hypertension, and heart disease, and can reduce quality of life and academic productivity. College students, as a group of early adults, are in a transition phase towards independence and are therefore vulnerable to lifestyle changes, including unhealthy eating patterns, fast food consumption, low physical activity due to busy studies, irregular sleep habits, and high academic stress. This study aims to determine the risk factors associated with obesity among students at the Islamic University of Ogan Komering Ilir in 2025. This study used a cross-sectional design with a quantitative approach. A sample of 95 students was selected using a purposive sampling technique. Data were collected through a structured questionnaire and body mass index (BMI) measurement to determine respondents' nutritional status. Independent variables included diet, physical activity, sleep quality, stress levels, and a family history of obesity. The results showed a prevalence of obesity of 17.9%. Bivariate analysis found a significant association between obesity and unhealthy diet (p=0.002), low physical activity (p=0.000), poor sleep quality (p=0.000), and high stress levels (p=0.001). Meanwhile, a family history of obesity showed a tendency to have an effect but was not statistically significant. These findings indicate that obesity in college students is largely influenced by modifiable lifestyle factors. Therefore, this study emphasizes the importance of health promotion interventions on campus, such as balanced nutrition counseling, increased access to sports facilities, stress management, and education on healthy sleep patterns. Promotive and preventive efforts undertaken from a young age are expected to reduce the risk of obesity and chronic disease in the future.

The Community Service Program (KKN) is a tangible form of student service to the community through the application of knowledge in the field. Nagacipta Village, Serang Baru Subdistrict, Bekasi Regency, was chosen as the location for the KKN because it has considerable potential for community economic development, particularly through the Micro, Small, and Medium Enterprises (MSME) sector, and faces various challenges in the fields of education, social affairs, and culture. The objectives of this activity are to empower the community through education in schools, MSME assistance, and increased social awareness in order to support sustainable village development. The implementation method used is a qualitative descriptive approach with a participatory element (Participatory Action Research/PAR). The stages involved observation, interviews, group discussions with village officials, youth, and the community, work program preparation, implementation, and evaluation. The main programs implemented included anti-bullying and hygiene education in schools, simple digital marketing training for MSMEs, environmental health education, and support for community social and cultural activities. The results showed an increase in students' awareness of hygiene and mutual respect, the development of MSME actors' knowledge of digital promotion through social media, and increased community participation in social and cultural activities. Documentation of the activities also showed the active involvement of the community and the support of village officials. In conclusion, the KKN program in Nagacipta Village made a positive contribution to community empowerment and MSME development.
