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.

This corpus-based study explores the acquisition patterns of English modal verbs by Indonesian EFL (English as a Foreign Language) learners through a comprehensive analysis of learner language data. The study utilizes a specialized learner corpus consisting of 2.5 million words drawn from both written and spoken productions of 450 Indonesian learners, covering various proficiency levels. The research focuses on examining the frequency patterns, semantic distributions, and error types associated with modal verb usage across the learner corpus. The study employs a combination of quantitative corpus linguistic methods and qualitative error analysis to uncover developmental trends and persistent difficulties in acquiring English modals. The findings highlight a significant underuse of epistemic modality, which expresses degrees of certainty, and an overreliance on core modals like "can," "will," and "must." Additionally, learners systematically avoid more complex modal constructions that are semantically nuanced and less frequent in their linguistic output. The analysis also reveals notable cross-linguistic influences from Indonesian, particularly in the areas of politeness marking and the expression of certainty. These interference patterns suggest that Indonesian learners may transfer modal expressions from their native language, leading to specific errors in the usage of English modals. Based on the findings, the study proposes a usage-based pedagogical framework that integrates corpus-informed instruction with explicit semantic mapping of modal meanings. This framework encourages teachers to address modal verb acquisition by emphasizing frequency-based approaches, contrastive semantic analysis, and corpus-driven awareness-raising activities. The research suggests that by focusing on the form-meaning-function relationships of modals in authentic contexts, learners can better understand and produce English modals accurately and appropriately. The findings have significant implications for enhancing modal verb instruction in EFL classrooms, especially for Indonesian learners.

In addition to improving interpersonal communication skills, this training also emphasized the importance of strategic communication in the context of advocacy and social mobilization. NGO administrators were trained to design campaign messages tailored to audience segments, including potential donors, corporate partners, and government stakeholders. An understanding of the importance of framing and emotional appeal was also emphasized, so that the messages delivered were not only informative but also able to inspire empathy and concrete action from the audience. During the training process, participants were also equipped with a basic understanding of digital communication, particularly in utilizing social media platforms as a tool to expand the reach of messages. Creative content strategies, effective posting scheduling, and the use of visual storytelling were introduced so that NGO administrators could build a positive image of their institutions in the digital space. These skills are crucial considering that the dynamics of public communication today are influenced by the speed and reach of social media.The positive impact of this activity was felt not only individually, but also institutionally.The NGO "Kakak Asuh" began to show an increase in public engagement through social media, an increase in the number of new volunteers, and the opening of opportunities for partnerships with external parties. This demonstrates that persuasive communication is not merely a means of conveying a message, but also a strategy for building strong, credible, and sustainable relationships with the wider community. Going forward, the sustainability of this training program is designed through a system of ongoing mentoring and support. This approach is expected to strengthen the implementation of the communication strategies learned and enable a comprehensive transformation of organizational communication. Thus, this PKM activity will not only have a short-term impact but also build a solid communication foundation to support the NGO's social mission in the future.

The Abbasid dynasty was one of the most influential Islamic caliphates and left a long legacy in the development of world civilization. Established in 750 AD and ending in 1258 AD, the Abbasid period is known as the Golden Age of Islam due to its extraordinary progress in various fields, including politics, economics, and science. This study aims to examine how the Abbasid political and economic policies and the development of science that took place during that period were able to contribute significantly to the progress of global civilization. This study uses a qualitative method with a descriptive-historical approach through the study of relevant literature in the last five years. The results of the study indicate that political stability and a structured bureaucratic system provided a strong foundation for economic growth and intellectual progress. The Abbasid government established a center of knowledge in Baghdad known as Baitul Hikmah (House of Wisdom). Here, scientists from various religious and cultural backgrounds gathered to translate, develop, and disseminate knowledge from Greek, Persian, Indian, and other scientific traditions into the Islamic world. Some of the great figures who emerged during this period included Al-Khwarizmi (mathematics), Ibn Sina (medicine and philosophy), and Jabir Ibn Hayyan (chemistry). Their discoveries and work became the foundation for modern science. However, the glory of the Abbasids slowly declined due to internal conflicts, power struggles, and the weakening of the caliph's authority. The peak of the fall occurred when Baghdad was attacked and destroyed by the Mongols in 1258 AD. However, the intellectual and cultural heritage of the Abbasid dynasty continues to have an important influence on the development of world science and civilization to this day.

Diarrhea remains a major health problem, contributing significantly to morbidity and mortality rates in children, especially in developing countries like Indonesia. This disease is often linked to poor sanitation, lack of access to clean water, and a lack of public understanding of proper hygiene practices. Toddlers are the most vulnerable group to diarrhea because their immune systems are not yet fully developed. Current diarrhea management efforts rely heavily on providing oral rehydration salts (ORS) and, in some cases, the use of antibiotics. However, pharmacological approaches are not always available or appropriate in all situations. Therefore, alternative treatments are needed that are safe, readily available, and scientifically proven to be effective. One natural ingredient with significant potential for treating diarrhea is honey. Honey is known to contain various active substances such as enzymes, antioxidants, and antimicrobial compounds that can fight various pathogens that cause diarrhea. Furthermore, honey is also known to help repair the integrity of the intestinal mucosa, stimulate the growth of beneficial bacteria in the digestive tract, and accelerate the healing process. Although the health benefits of honey are well-known, public knowledge—especially among mothers—about its use as an adjunct therapy for diarrhea remains limited. Recognizing the importance of mothers' role in caring for sick children, especially during diarrhea, educational interventions are needed to improve their understanding. This educational activity aims to equip mothers with accurate, easy-to-understand information that can be applied in their daily lives. In this case, the counseling was conducted at PMB Andina Palembang using communicative media such as leaflets and accompanied by live demonstrations to increase information absorption. To measure the effectiveness of this activity, evaluations were conducted through pretests and posttests using structured questionnaires. The results obtained showed a significant increase in mothers' knowledge scores after participating in the counseling.

Sleep disturbances are a common complaint among postpartum mothers, and this condition can affect the physical and psychological recovery process after childbirth. Untreated sleep disturbances can lead to various problems, such as fatigue, decreased quality of life, and even the risk of mental health disorders such as postpartum depression. One non-pharmacological approach that can be used to address these sleep disturbances is lavender aromatherapy. Lavender aromatherapy is known to have a calming effect that can help improve sleep quality. This community service activity aims to increase postpartum mothers' knowledge about the use of lavender aromatherapy as a complementary therapy to address their sleep problems. The activity was conducted in June 2025 at the Lismarini Independent Midwife Practice (PMB), using methods that included education, discussion, and distribution of informative leaflets. A total of 15 postpartum mothers participated in this activity, and to measure their knowledge, pre- and post-tests were conducted before and after the education session. The evaluation results showed a significant increase in participants' knowledge levels after participating in the education about lavender aromatherapy. Education about the use of lavender aromatherapy has been proven effective in increasing postpartum mothers' understanding of the benefits and how to use this therapy. Thus, lavender aromatherapy can be a beneficial health promotion strategy to support postpartum recovery. Through this activity, it is hoped that postpartum mothers can apply the knowledge gained to independently improve their sleep quality, thereby supporting their physical and mental health during the recovery period. This activity also contributes to efforts to improve overall public health and provides new insights for healthcare workers in educating postpartum mothers about safe and effective alternative therapies.

This study aims to evaluate the extent to which the Shopee e-commerce platform affects the sales rate of clothes in Pasar 16 Ilir, Palembang, which is known as one of the largest clothing trading centers in South Sumatra. The background of this research departs from the phenomenon of the rapid development of e-commerce in Indonesia, where Shopee dominates the fashion category and is the main choice of consumers in online shopping. The change in consumer behavior from conventional to digital shopping patterns encourages businesses in traditional markets to adjust strategies to remain relevant and competitive in the increasingly dynamic era of digital transformation. This research method uses a combination of quantitative and qualitative approaches. A survey was conducted on 100 sellers and 150 consumers to collect data on shopping habits, perception of promotions, and the impact of using Shopee on clothing sales. In addition, in-depth interviews with several business actors at Pasar 16 Ilir were conducted to gain a more detailed understanding of the adaptation strategies they implemented. Data analysis shows that Shopee's promotional features, such as discounts, cashback, and flash sales, are the dominant factors that increase consumer interest. Hedonistic aspects, including the convenience and pleasure of online shopping, as well as customer reviews, also have a significant influence on purchasing decisions. The results of the study confirm that the integration of Shopee with the traditional market contributes to the increase in the volume and sales value of clothes in Pasar 16 Ilir. The online-to-offline (O2O) synergy model helps merchants reach a wider market and improve their competitiveness. In conclusion, optimizing e-commerce platforms through effective promotion strategies, review management, and customer service is the key for MSME actors in facing competition in the digital era.

Disc discs are the main component in a motorcycle braking system that functions to convert kinetic energy into heat energy through friction. The geometric design of the disc, including the diameter and number of holes, affects the effectiveness of braking as well as the heat dissipation ability. This study aims to analyze the effect of variations in diameter and number of holes on disc discs on braking distance and disc temperature. The research method used was an experimental method with three variations in disc diameter (190 mm, 220 mm, and 260 mm) and three variations in the number of holes (30, 36, and 42 holes). The test was carried out through a controlled braking procedure at an initial speed of 40 km/h on flat road surfaces with stable weather conditions. Braking distance data is measured using ultrasonic sensors, while disc temperature is recorded with a high-accuracy infrared thermometer. The results showed that the diameter of the disc disc had the most significant influence on the braking distance. The larger the diameter, the greater the braking moment resulting so that the stopping distance becomes shorter. The number of holes in the disc also plays a role in heat dissipation because the holes enlarge the heat dissipation area. However, the increase in the number of holes tends to slightly increase the braking distance due to a reduction in the area of frictional contact field. The most optimal configuration is found on a 260 mm diameter disc with 42 holes, which results in the shortest braking distance of 8.25 meters and the lowest temperature rise of 4.47°C.  Statistical analysis using Two-Way ANOVA confirmed that the diameter and number of holes had a significant effect individually, but there was no significant interaction between the two. These findings confirm that the selection of the right disc dimensions is critical to improving braking performance, thermal efficiency, and rider safety.
