Hypertension is a chronic clinical condition characterized by persistently elevated blood pressure above normal physiological limits and is a major global health concern due to its strong association with cardiovascular morbidity and mortality. One important contributing factor to hypertension is hypercholesterolemia, or an abnormal increase in total cholesterol levels in the blood. Elevated cholesterol concentrations may accelerate arterial stiffness and increase vascular resistance, thereby worsening blood pressure regulation. This study aimed to describe the relationship between blood pressure status and total cholesterol levels among productive-age individuals diagnosed with hypertension. The study was conducted in July 2023 using a descriptive design. A total of 30 hypertensive respondents within the productive age range were selected through accidental sampling. Data collection involved direct measurement of blood pressure using a sphygmomanometer and assessment of total cholesterol levels through standard clinical procedures. The results showed that the majority of respondents were categorized as having Stage 1 hypertension. With regard to cholesterol profiles, 16 respondents (53%) exhibited normal cholesterol levels, 9 respondents (30%) had borderline high cholesterol levels, and 5 respondents (17%) were classified as having high cholesterol levels. These findings suggest that most hypertensive individuals in the productive age category present with cholesterol levels ranging from normal to borderline high, although a smaller proportion already experience clinically high cholesterol concentrations. The study highlights the importance of regular monitoring of both blood pressure and lipid profiles in productive-age individuals to prevent progression to more severe cardiovascular complications. Lifestyle modification remains a cornerstone in hypertension management, particularly increasing physical activity, adopting a balanced diet low in saturated fats, and maintaining good sleep hygiene. Such preventive strategies can help reduce the dual burden of hypertension and hypercholesterolemia, ultimately lowering the risk of long-term cardiovascular disease.

Education plays a fundamental role in shaping character, developing personality, and exploring students' potential. Schools should ideally be safe, comfortable, and conducive spaces for student growth and development. However, reality shows that the school environment is still vulnerable to negative behaviors such as bullying and sexual violence. Bullying is understood as aggressive behavior carried out repeatedly with the aim of harming the victim, whether through physical, verbal, social, or online media (cyberbullying). Meanwhile, sexual violence includes various forms of sexual acts without the victim's consent, which have serious impacts on psychological, social, and academic achievement. Sexual violence in schools not only harms the victims physically but also leaves deep psychological scars that may affect their future. To respond to this problem, KKM Group 30 Bina Bangsa University conducted a socialization activity entitled "Stop Bullying and Sexual Violence" at SMAN X, District Y. The main objective of this activity was to provide in-depth understanding, build awareness, and encourage mutual respect in the school environment. The outreach was conducted through several methods, including presentations by resource persons, educational drama performances depicting real-life cases, and interactive question-and-answer sessions involving active student participation. Interactive sessions are essential to engage students and encourage them to express their thoughts openly. The results of the activities demonstrated high student enthusiasm, increased understanding of the forms and impacts of bullying and sexual violence, and a growing awareness to report victims or witnesses. These activities emphasized that prevention is not solely the responsibility of schools but also requires collaboration between students, teachers, parents, and the wider community. This creates a safe, comfortable learning environment free from all forms of violence.

Background: Pregnancy is a physiological process experienced by every woman, but it can be accompanied by various discomforts, both physical and psychological. In the third trimester, hormonal, physical, and emotional changes often trigger complaints such as anxiety, difficulty sleeping, and discomfort. These conditions, if not managed, can negatively impact the health of the mother and fetus, including increasing the risk of pregnancy complications. One non-pharmacological approach that is increasingly in demand to address these problems is aromatherapy, namely the use of essential oils from plants as a complementary therapy. Objective: This literature study aims to explore the effectiveness of aromatherapy in reducing anxiety levels and improving sleep quality in pregnant women, especially in the final trimester. Methods: A narrative literature review was conducted by analyzing ten national journal articles published between 2014–2024. Articles were selected through a purposive sampling method based on the suitability of the topics with aromatherapy, pregnancy, anxiety, and sleep quality. Results: Most studies show that aromatherapy, especially with lavender, orange, and chamomile essential oils, has a positive effect in reducing anxiety levels and improving sleep quality. The mechanism of action of aromatherapy is thought to involve stimulation of the limbic system in the brain via the olfactory pathway, which plays a role in regulating emotions, inducing relaxation, and reducing sympathetic nervous system activity. These effects help reduce tension and facilitate better sleep in pregnant women. Conclusion: Aromatherapy has been shown to be a safe, easy-to-implement, and effective complementary intervention for addressing anxiety and sleep disturbances in pregnancy. Healthcare providers, particularly midwives, are advised to integrate this therapy into holistic antenatal care to support the overall well-being of pregnant women.

One way to empower pregnant women in this effort is through community service activities. This community service activity is a collaboration between STIKes Mitra Husada Medan and a practice in Bangun Rejo Village, Tanjung Morawa. Anemia can affect pregnant women at various stages of pregnancy. Therefore, this community service program is implemented in the form of a pregnancy class aimed at preventing and early detection of anemia. The target group includes pregnant women in their first, second, and third trimesters, with the hope of increasing their knowledge about anemia, thus creating physically and emotionally healthy mothers-to-be. The results of the community service program indicate positive changes following the community service, including an increased understanding of the symptoms of anemia, preventive measures, and active participation in early detection of anemia during pregnancy.

Children are one of the most vulnerable groups during disasters due to their limited physical and psychological resilience. Therefore, providing disaster mitigation education to children is essential to enhance their awareness, preparedness, and response capabilities in the face of potential disasters. This community service activity aims to increase children's understanding of disaster mitigation through both theoretical education and participatory simulations that reflect real-life scenarios. The activities were carried out using a cooperative-participatory approach in collaboration with the local Indonesian Red Cross (PMI) in Tanah Karo and members of the surrounding community. The stages of implementation included conducting a site survey, securing necessary permits, determining the time and location, coordinating with local stakeholders, and executing the service program. The educational activities covered disaster phases, including pre-disaster, during disaster, and post-disaster, with a focus on practical and age-appropriate learning strategies. The educational team involved an interprofessional group of facilitators who delivered the material through socialization and counseling sessions. The sessions were enthusiastically received by the children, indicating a high level of engagement and interest. However, findings revealed that children's knowledge of disaster mitigation was still minimal, emergency response plans were underdeveloped, and community involvement in disaster preparedness training remained low. This highlights the need for continuous and sustainable disaster education efforts, especially for children and communities in disaster-prone areas. By fostering early awareness and preparedness through ongoing education and simulation-based activities, it is expected that children will be better equipped to respond effectively and safely during disaster situations. Long-term, this approach also aims to build a more resilient and disaster-aware community.

 Matra Health is a form of health service specifically designed to maintain and improve public health in dynamic, complex, and constantly changing environmental conditions. This service plays a very vital role, especially in facing and handling various types of disasters, both natural disasters such as earthquakes, floods, and landslides, as well as non-natural disasters such as residential fires. One form of non-natural disaster that often occurs in densely populated areas is residential fires. This is caused by various factors such as unsafe electrical installations, a lack of public awareness of the dangers of fire, and buildings that are not resistant to heat or fire. Residential fires not only cause physical damage to buildings and infrastructure, but also cause various health problems, ranging from burns, respiratory problems due to smoke exposure, to psychological trauma, especially in vulnerable groups such as children, the elderly, and pregnant women. In response to these conditions, a dimensional health intervention activity was carried out from June 23 to 26, 2025 in areas affected by the fires under the coordination of the South Sumatra Regional Crisis Center. This activity aims to reduce health risk factors that arise after the fires through a series of actions such as multi-sector health surveillance, public health education, and distribution of logistical assistance. The activity also includes conducting rapid assessments using the Rapid Health Assessment (RHA) method, providing education on fire impact prevention, and distributing supplementary food to vulnerable groups. The results of the activity showed a significant increase in public understanding of the dangers of fire and the importance of preparedness for its impacts. Furthermore, the need to strengthen cross-sectoral coordination, such as health, disaster management, and social sectors, in disaster management was identified. It is hoped that this activity can serve as a model for strengthening community-based emergency response systems.

The betel nut (Areca catechu) is a tropical plant that thrives in Southeast Asia, including Indonesia. This plant has long been known in traditional medicine and local culture for its content of various beneficial active compounds. One form of its utilization that has rarely been scientifically studied is fresh betel nut juice. Therefore, this study aims to conduct a preliminary assessment of the characteristics of fresh betel nut juice, particularly from a physical, chemical, and microbiological perspective. The juice production process is carried out simply by squeezing fresh betel nuts without the addition of chemicals or heating. Based on initial observations, the betel nut juice exhibits a distinctive reddish-brown color and a sharp, pungent aroma. This color and aroma likely originate from the phenolic and alkaloid compounds naturally present in the betel nut. pH measurements indicate that the juice has a fairly high acidity level, which can affect the stability of microorganisms within it. Qualitative tests of the chemical composition of the betel nut juice indicate the presence of bioactive compounds, particularly tannins and alkaloids. Tannins are known to have antimicrobial activity, while alkaloids act as physiologically active compounds that can affect the nervous system. However, the presence of these compounds does not completely inhibit the growth of microorganisms. Through simple isolation of microorganisms from the fresh juice, bacteria from the genus Lactobacillus spp., which are typically associated with natural fermentation processes, were found. The presence of these bacteria indicates that fresh areca nut juice can be a potential growth medium for certain microorganisms, particularly lactic acid bacteria. This finding opens up opportunities for further research into the use of areca nut juice as a natural fermentation agent that may have functional and probiotic value.

This research is motivated by the high intensity of activity in the apron area, the limited number of personnel, and the implementation of a shift work system in the Apron Movement Control (AMC) unit at Halim Perdanakusuma Airport. These conditions have the potential to cause excessive workloads for personnel, which can impact the effectiveness of operational supervision and disrupt their physical and mental health. The main objective of this study is to analyze the workload of AMC personnel and determine the ideal number of workers to ensure optimal supervision in the apron area. This study uses a quantitative descriptive approach. Data collection techniques were carried out through direct observation and the distribution of questionnaires to all personnel activities in the AMC unit. Data analysis used the Full Time Equivalent (FTE) method to calculate the total actual working time required, and compared it with the standard full-time working hours according to employment regulations. The results showed that the workload of AMC personnel is quite high. Of the seven personnel analyzed, two people obtained an FTE value above 1.28, indicating an overload condition, four people were in the FTE range of 1.00 to 1.28, which is considered normal, and one person had an FTE value below 1.00, indicating an underload condition. These findings indicate an imbalance in the distribution of workload among personnel. As a result, some personnel must perform multiple tasks simultaneously, potentially compromising the quality of oversight and operational safety in the apron area. Based on these findings, a re-evaluation of the division of tasks and workforce within the AMC unit is recommended to create a proportional workload and support optimal safety and operational performance at Halim Perdanakusuma Airport.
