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.

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.

This study aims to explore the perspective of Physical Education, Sports, and Health (PJOK) teachers and classroom teachers regarding the form and effectiveness of cooperation in the implementation of the Pancasila Student Profile Strengthening Project (P5) with the topic of Sustainable Lifestyle at Pajajaran State Elementary School. The implementation of the Independent Curriculum emphasizes the importance of collaborative, comprehensive, and contextual learning, where synergy between teachers is the main foundation for the success of thematic projects. This collaboration is essential to ensure that learning not only develops cognitive aspects, but also forms character and environmental awareness in students. The research method used is a qualitative approach with data collection techniques through semi-structured interviews, direct observation during the learning process, and document analysis such as learning implementation plans and P5 project reports. The data was analyzed with the stages of data reduction, data presentation, and conclusion drawing to obtain a comprehensive picture of the teacher's collaboration strategy. PJOK teachers play a role in field practice, such as teaching physical activities that prioritize the principles of sustainability and healthy living habits. Meanwhile, classroom teachers emphasized strengthening conceptual material on sustainability through discussions, literacy, and creative projects. The results of the study show that the synergy between PJOK teachers and classroom teachers creates more effective and meaningful learning. Challenges that arise include limited time for coordination, differences in teaching styles, and lack of a comprehensive understanding of sustainability concepts. However, motivation, commitment, and good communication are key factors to overcome these obstacles. This research emphasizes that teacher collaboration is crucial in supporting the successful implementation of the Independent Curriculum, while instilling the values of environmental care, independence, and social responsibility in students.

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.

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.

Education is a conscious and structured effort aimed at creating an environment and process that actively facilitates learners in developing their full potential. This includes nurturing their spiritual and moral values, self-control, intelligence, strong character, and essential life skills required for personal development and meaningful contributions to society, the nation, and the global community. At its core, education serves to empower students to realize and utilize their capabilities for future life challenges. It acts as a foundational medium through which younger generations acquire essential life skills, enabling them to integrate effectively into society. Moreover, education plays a pivotal role not only in the personal growth of individuals but also in the advancement of a nation. High-quality education is defined by its capacity to equip students with the competence to confront and resolve real-world problems. This notion becomes increasingly critical as learners transition from academic settings to the workforce and community life, where they are expected to apply their knowledge and skills practically. However, the success or failure of educational outcomes is largely determined by the curriculum. A well-designed curriculum should cultivate critical awareness and empower students to navigate complex social and professional environments. It should also promote creativity, critical thinking, and collaboration, which are essential skills in today’s rapidly changing world. Furthermore, education should not be viewed merely as a means to acquire knowledge but as a holistic process that fosters emotional intelligence and social responsibility. By integrating various disciplines and encouraging interdisciplinary learning, education can help students develop a broader perspective on global issues, such as climate change, social justice, and economic inequality. In addition, the role of educators is crucial in this process.
 

Rapid technological developments have penetrated various aspects of human life, including data and information security. Amidst the threat of data leaks and misuse, information protection has become crucial. One solution to maintain data confidentiality is to implement cryptography technology. Cryptography is the study of techniques to secure messages so they cannot be read by unauthorized parties. This process is carried out by encoding the original message (plain text) into an unreadable form (cipher text), which can only be understood by those who possess the key to decrypt it. This study used the Caesar Cipher algorithm, a form of classical cryptography. This algorithm uses a substitution method, where each letter in the message is shifted by a certain amount based on a predetermined key. Caesar Cipher is a symmetric algorithm, meaning the key used for encryption is also used for decryption. The security of this algorithm lies in the secrecy of the key, which is known only to the sender and recipient of the message. This method is relatively simple, but still relevant for securing data with low to medium sensitivity levels. This study used WhatsApp messages as the object to be encrypted using the Caesar Cipher algorithm. The results show that encrypted messages become unintelligible without prior decryption. This demonstrates that the Caesar Cipher can protect messages from unauthorized parties. Therefore, implementing this algorithm can be an initial solution for maintaining data confidentiality in digital communications, especially on platforms vulnerable to eavesdropping or unauthorized access. Its primary benefit is maintaining message integrity and confidentiality to prevent misuse.
