Hypertension is a global health problem whose prevalence continues to increase every year. This condition is not only a major cause of cardiovascular disease but also contributes to high morbidity and mortality rates in various countries, including Indonesia. One risk factor mitigating this problem is low public awareness of the importance of routine blood pressure monitoring. Therefore, promotive and preventive efforts are needed through health education that is easy to understand and can be applied in everyday life. This community service activity aims to increase public knowledge, especially among the elderly, about hypertension and the application of simple non-pharmacological therapies. One method introduced is soaking feet in warm water with added salt. This method is considered safe, practical, and cost-effective, making it suitable for elderly people in rural communities. The activity was carried out in Mauleng Hamlet, Paccing Village, Awangpone District, Bone Regency, with 15 elderly participants. The activity method included a pre-test to determine the participants' initial level of knowledge, counseling on hypertension, direct compression using warm water and salt foot soaks, and a post-test to measure knowledge improvement. The results showed a significant increase in participants' level of knowledge. Prior to the outreach program, only 7% of respondents had sufficient knowledge about hypertension and non-pharmacological therapy. After the outreach and reinforcement program, this figure increased to 87%. These results indicate that health education combined with practical demonstrations is highly effective in increasing public knowledge. Therefore, it can be concluded that educational activities and warm salt foot soak therapy have proven effective in increasing public understanding of non-pharmacological hypertension management and have the potential for widespread implementation as a health promotion measure.

This community service activity was carried out with the primary objective of improving the Qur'an reading skills of the women of the Majelis Taklim (Islamic study group) through systematically designed intensive training. Reading the Qur'an properly and correctly is an obligation for every Muslim, but in reality, many people, especially the women of the Majelis Taklim (Islamic study group), still face obstacles in aspects of makhraj, tajwid, and fluency. This condition encourages the need for a targeted coaching program to improve the quality of Qur'an reading, so that the values ​​of Islamic teachings can be understood and practiced more accurately. The training was held in early July 2025 with a total of 35 participants from the Majelis Taklim (Islamic study group) with diverse reading ability backgrounds. The methods used included lectures, demonstrations, reading practice, individual guidance, and ongoing evaluation at each meeting. This approach was chosen so that participants not only gain theoretical knowledge but also practical skills that can be immediately applied. Evaluation was carried out through observing reading ability, courage to ask questions, and active participation in group exercises. The results of the activity showed a significant improvement in the participants' Qur'an reading skills, both in terms of letter pronunciation, application of Tajweed rules, and fluency in reading holy verses. The participants' enthusiasm was evident in their eagerness to participate in all sessions, their sincerity in practicing, and their active interaction during the learning process. Furthermore, this activity also fostered new motivation for participants to continue improving their reading quality independently and create a conducive learning environment in the Islamic study groups. Thus, this training proves that the right learning strategy, supported by high motivation from participants, can have a positive and sustainable impact on improving the quality of Quran reading. It is hoped that this type of program can be replicated in other Islamic study groups so that its benefits are even broader for the community.

Mathematics learning, particularly in geometry, is often perceived as abstract and less engaging by students, leading to reduced interest and creativity. One of the geometry topics that demands a more creative and concrete approach is the tessellation of flat shapes, which emphasizes the understanding of patterns, symmetry, and regularity of shapes. The absence of contextual learning media has contributed to students’ low enthusiasm and limited ability to apply concepts in real-life contexts. This community service activity was designed to address these challenges by enhancing students’ creativity and conceptual understanding through the use of ceramic media as an innovative and enjoyable learning tool. The program was conducted at SD Negeri 1 Rowosari, Tembalang District, Semarang City, involving mathematics teachers, elementary school students, and university students. The implementation method included training and mentoring sessions. Activities encompassed the introduction of tessellation concepts, hands-on demonstrations, and the guided creation of tessellation patterns using ceramic media. Participants consisted of teachers and students who actively engaged in both theoretical and practical sessions. Evaluation was conducted through pre-test and post-test questionnaires administered before and after the training. The results revealed a significant improvement in students’ average scores after the activity. Pre-test data showed that approximately half of the students scored above the average, with two students achieving nearly perfect scores. Post-test results indicated that most students demonstrated increased understanding and creativity in applying tessellation concepts. Nevertheless, a small number of students still required further guidance, particularly in translating abstract tessellation concepts into real-life applications. Overall, the findings suggest that integrating ceramic media into mathematics learning is effective in making abstract geometry concepts more tangible, stimulating students’ creativity, and improving learning outcomes, especially in the topic of tessellation of flat shapes.

Pogalan Village in Pakis District, Central Java, is known as a horticultural agricultural center, with abundant vegetable production every year. However, behind this potential, this village faces a serious problem in the form of large amounts of organic waste generated from harvest residue and agricultural processing. Waste that is not managed properly has the potential to cause environmental pollution, reduce the village's aesthetics, and become a source of disease spread. To address these problems, the Tidar University Community Service Program (KKN-50) Team conducted a socialization activity for Black Soldier Fly (BSF) maggot cultivation as an environmentally friendly and economically valuable organic waste management solution. BSF maggots have been proven to decompose organic waste by up to 60% in a short time and produce useful by-products, such as dried maggots as high-protein animal feed and kasgot (used maggots) that can be used as organic fertilizer. The activity was held on July 31, 2025, at the Pogalan Village Hall, with the main participants being PKK mothers as agents of change at the household and community levels. The implementation method included initial observation of the village's potential and problems, creation of a maggot cultivation prototype, theoretical material outreach, and live demonstrations of the cultivation process. The material provided covered the BSF life cycle, cultivation techniques, selection of growing media, maggot population management, and utilization of cultivation products. The results of the activity showed high enthusiasm from participants, as reflected in the many questions and discussions during the training session, as well as their increased understanding of the benefits and techniques of maggot cultivation.

Type II diabetes mellitus (Type II DM) is a chronic disease that requires long-term self-care skills to prevent serious complications. However, many patients have difficulty managing blood sugar levels independently due to a lack of structured and ongoing education. The Student Creativity Program (PKM) aims to improve the self-care skills of Type II DM patients through an educational approach based on the Self-Care Deficit theory from Dorothea Orem. The activity was carried out in Bonto Ramba, the working area of the Tamalanrea Makassar Health Center, involving 35 participants (33 women and 2 men). Interventions were carried out through interactive counseling, demonstrations of diabetic foot wound care, practice simulations, and the distribution of easy-to-understand educational media. Evaluation was carried out using a pre-post test to measure knowledge improvement and an observation sheet to assess the ability of self-care practice. Results showed a significant improvement in participants' self-care knowledge and skills after the intervention. In addition, family involvement in assisting patients has also increased, strengthening the sustainability of self-care behavior. Participants gave positive feedback on the method of delivering material that was contextual and relevant to daily life. The supportive-educational approach used has been proven effective in empowering patients and building awareness of the importance of self-control of health conditions. This program not only contributes to improving the quality of life of Type II DM patients, but also strengthens the role of the family as the main support in the treatment process. In conclusion, structured education based on Orem theory can be used as an intervention model that can be replicated in other areas with high prevalence of DM, as a promotive and preventive strategy in community-based management of chronic diseases.

Waste management remains a serious problem, particularly in rural areas, which generally have relatively low levels of environmental awareness. Inorganic waste such as plastic, glass, and aluminum is a major concern because it takes hundreds of years to decompose naturally. This situation poses potential long-term environmental hazards, including soil and water pollution, and ecosystem disruption. Therefore, effective educational efforts are needed to raise public awareness of waste issues. This community service activity was carried out in Sarah Perlak Village, Sungai Mas District, West Aceh Regency. The focus of the activity was the installation of educational signs containing information about the decomposition time of various types of waste. Implementation methods included direct observation to identify specific problems at the site, informal outreach to local residents, demonstrations related to waste sorting, and the creation and installation of educational signs. The signs were made from wooden planks and decorated with real waste such as plastic bottles, aluminum cans, and used paper, thus providing a tangible visualization to the community. The results of the activity showed that the visual approach through educational signs was able to attract the attention of residents, both children and adults. The information was presented clearly and accompanied by real-life examples, making the message easier to understand and remember. In addition, direct interaction through outreach and demonstrations provided an opportunity for residents to ask questions and share experiences related to waste management. Overall, this educational medium has proven effective in conveying environmental messages, raising awareness, and motivating the community to start sorting and reducing waste at the source. Going forward, this program is planned to be expanded through training in processing waste into useful products, thereby not only reducing pollution but also providing economic benefits to the community.

Hypertension is a condition characterized by elevated blood pressure, where the systolic pressure exceeds 140 mmHg and the diastolic pressure exceeds 90 mmHg. If not properly treated, hypertension can lead to severe complications, increased morbidity, and even mortality. This condition occurs when the heart works harder than usual to pump blood (systolic) and the blood flow returning to the heart (diastolic) also experiences increased pressure. One of the efforts to prevent the progression of hypertension from a primary to a secondary stage is through non-pharmacological treatments. One such treatment includes the use of natural remedies like celery leaves. Celery leaves contain active compounds such as flavonoids and potassium that are believed to help lower blood pressure by relaxing blood vessels and increasing the excretion of sodium through urine.This community service activity was carried out in Purwodadi Village and aimed to increase public awareness, especially among families, regarding hypertension and its non-pharmacological management using natural ingredients that are easy to find and affordable. The method used involved health education through counseling and direct demonstrations of how to prepare and consume celery leaf boiled water. Participants were actively involved in learning how to select, clean, boil, and properly consume the celery leaf water as a herbal drink.The results of the activity showed a significant improvement in community knowledge and understanding related to hypertension and the benefits of using celery leaves as a traditional remedy. It is hoped that after this activity, the local community will be able to independently apply this knowledge and routinely use boiled celery water as a preventive measure to maintain normal blood pressure and reduce the risk of complications. This effort is part of promotive and preventive health services to improve the quality of life and promote a healthy lifestyle at the village level.
