Early childhood education is a fundamental phase in the formation of children's character, literacy skills, and social skills. However, children's basic literacy skills in various regions of Indonesia, including Aisyiyah 2 Aimas Kindergarten, Southwest Papua, are still relatively low, exacerbated by limited learning media, conventional teaching approaches, and teachers' lack of understanding of inclusive education and positive discipline. This study aims to analyze the implementation of basic literacy training with inclusive education and its impact on improving teacher competence. The method used is a one group pretest in the context of community service, involving six teachers as subjects. The program is carried out through three stages: pre-training (observation, interview, and pretest), training (literacy materials based on the DUBT model—Listen, Speak, Read, Write; inclusive education; and positive discipline), and post-training (posttest, classroom observation, reflection, and mentoring). The results showed a significant increase in teacher competence, as shown by the increase in the average pretest score from 57.5 to 84.8 in the posttest. In addition, 83% of teachers are able to implement literacy practices such as reading picture stories, letter cards, reading corners, and dialogue interactions with children. Teachers also began to show acceptance of children's diversity and applied positive discipline without punishment. These findings show that inclusion-based literacy training is effective in improving teachers' pedagogical knowledge and practices. This research emphasizes the importance of developing adaptive, humanist, and equitable literacy as the foundation of early childhood learning.

Islamic financial literacy in rural areas remains relatively low due to limited access to information and education, leading people to prefer traditional investments such as livestock and plantations. The activity was carried out by the Community Service Program (KKN) team in collaboration with the Indonesia Stock Exchange (IDX) as the main speaker and the village government as a supporting partner. The methods used included observation, counseling, interactive discussions, and simple simulations of Islamic investment practices. The results revealed high enthusiasm among participants, reflected in their active engagement and significant improvement in understanding the concepts, principles, and products of Islamic investment. The community began to realize that Islamic capital market investments are not only halal and safe but also offer long-term economic benefits. This activity positively influenced the community’s mindset to view Islamic financial investment as a complementary form of traditional investment. The program also opened opportunities for forming a village-based Islamic investor community and establishing a financial literacy center as a follow-up initiative. Therefore, this program plays a vital role in strengthening Islamic financial inclusion in rural areas and serves as an initial step toward creating a financially literate, independent, and economically productive society.

Chronic kidney disease (CKD) is a growing global health concern that frequently remains undiagnosed until advanced stages. Early detection through simple laboratory screening is essential to prevent disease progression and associated cardiometabolic complications. This community service program aimed to assess kidney function using serum creatinine and estimated glomerular filtration rate (eGFR), while increasing public awareness regarding CKD prevention. A total of 59 participants were included, with a mean age of 39.15 ± 15.39 years (range 16–75 years), predominantly female (74.58%). The mean serum creatinine level was 1.0 ± 0.19 mg/dL, and the mean eGFR was 91.08 ± 20.53 mL/min/1.73 m². Most participants demonstrated normal kidney function (28.8%) or mild decline (21.6%). A progressive reduction in eGFR with increasing age was observed, reflecting the physiological decline in nephron mass and renal perfusion. The program also provided education on kidney-protective practices, including optimal blood pressure control, diabetes management, adequate hydration, and avoidance of nephrotoxic agents. This intervention improved participants’ understanding of CKD risk factors and the importance of regular screening. In conclusion, serum creatinine and eGFR evaluation offer simple, accurate, and practical tools for early CKD detection, supporting promotive–preventive strategies to slow disease progression and enhance quality of life in at-risk populations.

Toddler age is often called the golden period because during this period brain nerve development occurs, especially myelination, as well as a critical period. The golden period can be achieved if toddlers' nutritional needs are optimally met. On the other hand, if babies and toddlers do not get the food they need, the golden period will change into a critical period, thus disrupting their growth and development. The level of education of parents will affect the health and well-being of children, because this is inseparable from the nutritional status of children. Mothers with a high level of education will have a clearer opportunity to absorb information compared to mothers with less or no education. With a good level of education, it is hoped that a mother will be willing and able to behave well in order to improve her child's nutritional status. This Community Service activity aims to provide health education on balanced nutrition to reduce stunting in the community, especially mothers with toddlers in Desa Cangguk, Kecamatan Tanah Pasir, Kabupaten Aceh Utara. This activity used a participatory approach involving lecturers, students, health workers, and the community. The results showed an increase in public understanding and awareness of stunting prevention. It is hoped that this activity will raise public awareness about balanced nutrition for children

The traditional homes of indigenous communities in Indonesia are highly vulnerable to natural disasters, particularly earthquakes, due to Indonesia's location in the Pacific Ring of Fire, which experiences high seismic activity. This situation demands the strengthening of traditional buildings to withstand potential earthquakes. Stilt houses, as a form of traditional architecture, possess characteristics that actually support earthquake resilience, such as flexible structures, the use of lightweight materials, and the application of local wisdom passed down through generations. With the development of modern construction techniques, stilt houses have the potential to become safer and more adaptable dwellings to earthquake shocks. However, indigenous communities, particularly those living in earthquake-prone areas and with lower levels of education, often face limited knowledge and skills related to the basic principles of earthquake-resistant construction. This lack of understanding results in traditional house construction without considering structural safety aspects, ultimately increasing the risk of serious damage and even collapse during an earthquake. These impacts not only threaten life but also cause significant material losses. This community service activity aims to improve the preparedness and resilience of the Sentani Indigenous community by developing earthquake-resistant stilt house models, increasing knowledge and skills in earthquake-safe house construction and maintenance, and encouraging the use of innovative technology and materials. The expected outcomes are the creation of model houses that can serve as examples and the dissemination of information on earthquake-resistant construction technology.

Moreover, the active involvement of students created an inclusive learning environment that was accessible to various community groups. The findings indicate that the presence of KKN students contributed positively to cultivating entrepreneurial motivation, particularly among youth and micro-business actors. This improvement was reflected in changes in mindset, interest in initiating halal businesses, and increased awareness of applying sharia principles in daily economic activities. Thus, the KKN program not only provides practical experience for students but also offers a tangible contribution to strengthening sharia-based economic empowerment at the village level.

This study aims to examine the use of piggy banks as a means of financial literacy education among elementary school students. Piggy piggy banks are seen as a simple but effective learning medium in instilling the habit of saving, managing money, and forming a frugal character from an early age. Through a qualitative descriptive approach, this research involves students, teachers, and parents as the main data source with interview and observation techniques. The results of the study show that the use of piggy banks not only increases children's understanding of the concept of money and economic value, but also fosters financial responsibility and awareness from an early age. Teachers play an important role in providing direction and assistance, while the role of parents is a reinforcement of the practice of saving at home. In addition, saving through piggy banks has been proven to increase motivation to learn, because children feel that they have financial goals that they want to achieve. Education through piggy banks is the first step in building a strong financial literacy foundation, so that children are used to planning their money wisely and consistently. Thus, piggy banks can be used as effective contextual learning innovations at the elementary school level.
