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.

Depression is one of the mental health problems that often arise in patients with chronic diseases, such as diabetes mellitus, hypertension, and chronic kidney failure. This condition not only impacts the patient's quality of life, but also affects the treatment process and the burden on the family. However, mental health literacy in the community is still low, so targeted preventive and curative efforts are needed. The Community Service Program (PKM) aims to improve people's mental health through educational interventions with scientific booklet media that are easy to understand and apply. The activity method is carried out in a participatory manner, including the preparation stage, socialization, educational implementation, and evaluation. Education is provided to the community with a focus on preventing depression through a healthy lifestyle, stress management skills, and early intervention efforts by seeking professional support. Evaluation is carried out through pre-post tests, observations, and group discussions. The results of the activity showed an increase in public knowledge about depression, a change in attitudes to be more open in expressing feelings, as well as practical skills in relaxation, maintaining sleep patterns, and building social support. Participants also better understand the importance of seeking professional help when depressive symptoms are getting worse. The conclusion of this PKM is that the scientific booklet has proven to be effective as a preventive and curative educational intervention medium, and can be an innovative strategy in improving the mental health of people affected by chronic diseases.

Global data shows that more than 60% of adolescents report experiencing moderate to severe stress due to academic and social demands. Physical activity plays an important role in maintaining adolescent mental health. Regular physical activity can stimulate the release of endorphins, improve cognitive function, reduce muscle tension, and reduce levels of cortisol, the main hormone associated with stress. One of the easiest, cheapest, safest, and most accessible forms of physical activity is walking. Walking is a moderate-intensity aerobic activity that has been proven to improve mood, improve sleep patterns, and reduce anxiety. The purpose of this study was to determine the effectiveness of walking as a physical activity on stress disorders in adolescents. The research method used a quasi-experimental design with a pretest-posttest control group approach, involving 44 participants, comprising 22 intervention and 22 control subjects. The walking activity was conducted for three consecutive days, with a duration of 60 minutes, from 16:00 to 17:00 WIB, on 16-18 December 2024. The sample criteria were first-year nursing students in their first semester who performed walking activities continuously for three days. The results showed a significant difference in stress levels before and after the intervention, with a significance level of (Z=-3.557, p=0.000). This means that there was a significant difference in stress levels between before and after the physical activity intervention. The difference in stress levels before and after the intervention in the control group was significant (Z=-1.000, p=0.317). This means that there was no difference in stress levels in the control group. The difference in stress levels between the intervention group and the control group after treatment was significant (Z=-3.445, p=0.001). This indicates that there is a significant difference in stress levels between the intervention group and the control group after the physical activity intervention. Walking is an effective, affordable, and feasible intervention for the adolescent population as a promotive and preventive strategy in stress management.

Daily drinking water requirement for healthy individuals is a crucial factor in maintaining health and physiological balance. For individuals involved in intense physical activity or exercise, fluid requirements can increase significantly, with recommendations reaching 3 to 4 liters per day to replace fluid loss through sweat, so researchers consider it important to discuss the provision of clean drinking water installations with the application of Reverse Osmosis (RO) machines that utilize PDAM water as a source, which is in the Candrasa complex to support the fulfillment of drinking water needs for the Indonesian Navy Academy Cadets. AAL is a military educational institution that requires a supply of safe and high-quality drinking water for the Cadets so that the learning and training process can run smoothly. This study covers the daily drinking water needs of AAL Cadets, the current condition of the drinking water supply, and the concept of the RO machine itself in the Candrasa complex by utilizing PDAM water to produce healthy and suitable drinking water for AAL Cadets.

The PKK group also showed high enthusiasm in disseminating food safety information. This program enhances the capacity of PKK as agents of change, strengthens the culture of food safety at the household level, and supports sustainable education through collaboration with the village government and health centers. It is hoped that this can be replicated in other villages.

The meaning of gratitude according to the perspective of the Qur'an and its relationship to modern human life which is influenced by technological advances, materialistic lifestyles, and social pressures. In the view of the Qur'an, gratitude is not merely expressed through words, but involves the awareness of the heart, verbal words, and real actions as a form of recognition of the blessings given by Allah SWT. Gratitude also functions as a reflection of faith that combines spiritual, moral, and social elements. In the context of modern life, the meaning of gratitude has shifted due to consumptive lifestyles and the culture of seeking recognition on social media, which has an impact on decreasing feelings of satisfaction and inner peace. This study uses a qualitative approach with a library research method through a review of the verses of the Qur'an, tafsir books, and various relevant academic literature. The results of the study show that the teachings of gratitude in the Qur'an play an important role in maintaining spiritual, emotional, and spiritual balance in the midst of modern life. The application of an attitude of gratitude has been proven to improve mental health, strengthen social relationships, and reduce materialistic tendencies. Furthermore, the value of gratitude can serve as a moral guideline for Generation Alpha, enabling them to balance technological advancement with spiritual life. Overall, the teachings of gratitude in the Quran remain universally relevant, not only as a religious obligation but also as a spiritual and social necessity that can bring happiness, serenity, and meaning to life amidst the dynamics of the digital age.

Hypertension is one of the main risk factors that can cause damage to target organs, including the eyes. One of the complications that often occur in hypertensive patients is hypertensive retinopathy, which is damage to retinal blood vessels due to a persistent increase in blood pressure. This damage can be progressive and asymptomatic in the early stages, so it often goes undetected until severe visual disturbances appear. This study aims to identify and analyze the role of blood pressure control in the prevention of ocular complications in hypertensive patients through a literature review. The method used is literature review by selecting national and international research articles published in 2021–2025 from the PubMed, ScienceDirect, Google Scholar, and Cochrane Library databases. Inclusion criteria include full-text articles, relevant research designs, and discussing the relationship between blood pressure control and ocular complications. The results of the study showed that uncontrolled blood pressure increased the risk of retinal damage, decreased ocular perfusion, and microvascular changes detected through funduscopy and Optical Coherence Tomography Angiography (OCTA) examinations. Some studies have concluded that stable blood pressure control, not just the average value of blood pressure, has a significant effect in preventing the progression of hypertensive retinopathy. In addition, regular eye exams have been proven to be able to detect retinal changes early, so that preventive interventions can be carried out in a timely manner. Thus, optimal blood pressure control, therapy adherence, healthy lifestyle education, and regular retinal examinations are effective strategies in preventing ocular complications and maintaining vision quality in hypertensive patients.

Diabetes mellitus (DM) is a metabolic disease characterized by elevated blood glucose levels. This condition includes several types, such as type 1 and type 2 diabetes. It occurs when the body is unable to produce enough insulin, experiences impaired insulin function, or faces a combination of both. As a result, glucose cannot be effectively absorbed by the body’s cells and accumulates in the bloodstream, leading to high blood sugar or hyperglycemia. If this condition persists, the buildup of glucose can cause various disorders in different organs. Without proper management, diabetes may lead to severe and life-threatening complications. Chronic hyperglycemia in diabetic patients is associated with long-term damage, dysfunction, and even failure of vital organs such as the eyes, kidneys, nerves, heart, and blood vessels. In this activity, percentage-based methods and demonstrations of blood glucose testing were used as educational tools for students. The results showed that students’ awareness of the dangers of elevated blood sugar levels remains low. Many of them are still unfamiliar with the importance of regular blood glucose monitoring and maintaining a healthy lifestyle to prevent diabetes. Therefore, continuous efforts are needed to provide education and outreach on the prevention and early management of diabetes mellitus.

Hypertension remains a major health problem with high prevalence, often linked to poor lifestyle habits and low self-efficacy in managing one’s health. Effective hypertension management requires not only support from health professionals but also encouragement from family members who can remind patients to adhere to treatment and provide emotional support. This study aimed to analyze the relationship between self-efficacy, lifestyle, and family support with hypertension among Prolanis members in the working area of Puskesmas Oesapa, Kupang City. Using an observational analytical approach with a cross-sectional design, the study involved 65 hypertensive Prolanis members selected through simple random sampling. Data collection was conducted using a structured questionnaire. The findings showed significant relationships between self-efficacy, physical activity, and diet with hypertension status (p-value = 0.000). However, resting habits were not significantly associated with hypertension (p-value = 0.063), and family support also showed no significant relationship (p-value = 0.388). The study recommends that the Puskesmas continue to strengthen Prolanis activities and enhance health education, particularly regarding the importance of maintaining a healthy lifestyle through proper dietary management and regular light physical activity tailored to the abilities of Prolanis members.

Occupational Safety and Health (OHS) is a fundamental aspect in maintaining the smooth production process while maintaining the welfare of workers in the food manufacturing industry. This study aims to analyze in depth the implementation of the OHS program at PT XY, a medium-scale food manufacturing company, by reviewing the applicable policies, program implementation, obstacles encountered, and potential strategies for improvement. The study used a qualitative descriptive approach through direct observation in the production area, semi-structured interviews with 12 informants consisting of managers, supervisors, and operators, and a review of various internal company documents related to OHS. The research findings revealed that the company has a formally formulated OHS policy supported by regular training, but its implementation is not evenly distributed across all work units. Key weaknesses include inconsistent internal audit implementation, low worker awareness in reporting incidents, and a limited number of human resources with specific OHS competencies. Based on these findings, the study recommends strengthening the risk-based OHS management system, increasing human resource capacity, and integrating OHS indicators into the production performance evaluation system to support more optimal OHS implementation in the company.

Elevated blood pressure above the normal range is a hallmark of a medical condition known as hypertension. It is estimated that as the population ages, the number of hypertension cases will also increase. If this condition is properly managed early, it can be controlled. Controlling daily eating habits is one of the most effective non-pharmacological methods for lowering blood pressure. Therefore, finding alternative food sources that can naturally lower blood pressure is crucial. Red dragon fruit (Hylocereus polyrhizus), which is high in fiber, potassium, and antioxidants such as vitamins B, C, and E, is one possible option. These nutrients are important for maintaining blood vessel flexibility and controlling hypertension. The purpose of this study was to determine the effect of red dragon fruit juice consumption on blood pressure in the Paku Village Community Health Center (Puskesmas Pembantu) operational area. A single-group pre-experimental design was used in this study. A paired-sample t-test was used to assess the data. Based on the findings, the average systolic blood pressure was 184 mmHg before consuming red dragon fruit juice and decreased to 164 mmHg after the intervention. With a t-value of 23.4, a correlation of 0.96, and a p-value of 0.000 (p < 0.05), this decrease was statistically significant. Meanwhile, the average diastolic blood pressure dropped from 101 mmHg to 84 mmHg, with a correlation of 0.961, a t-value of 18.65, and a p-value of 0.000 (p < 0.05). These results indicate that consuming red dragon fruit juice significantly lowers blood pressure, with an average decrease in systolic pressure of 20 mmHg and diastolic pressure of 17 mmHg.
