This research was motivated by the lack of teaching materials that align with the characteristics and needs of students. One of the main issues identified is the use of learning modules that are not yet adapted to local culture and fail to provide meaningful learning experiences. To address this problem, the researcher developed a culturally based module inspired by Minangkabau songket. This study employed a Research and Development (R&D) design following the development stages proposed by Sugiyono. The results show that the developed module achieved a validity level of 82.58% (categorized as very valid), a practicality level of 87.6% (very practical), and an effectiveness level of 83.3% (very effective). Based on these findings, it can be concluded that the ethnomathematics-based module on Minangkabau songket for Phase F of the Health Department at SMAN 1 Lareh Sago Halaban in the 2023/2024 academic year meets the criteria of being valid, practical, and effective. Therefore, it is considered suitable for use as a culturally contextual teaching material that integrates local values into the learning process.

This study examines and analyzes the strategies of mosques as a medium for empowering the community's economy in the city of Watampone. The main focus of the research is to identify the types of strategies implemented by mosques, the challenges faced in carrying out economic programs, and to formulate effective strategies for improving community welfare based on mosque-centered initiatives.The research method used is qualitative descriptive, with data collected through interviews, observations, and documentation of four main mosques in Watampone City: Masjid Agung al-Malkaz al-Ma’arif, Masjid Nurul Hamirah, Masjid Tua Al-Mujahidin, and Masjid Songko’ Recca. The findings reveal that mosques in Watampone have implemented two strategic approaches to economic empowerment: offline (physical) and online (digital). (1) Offline strategies are carried out through the utilization of physical assets such as hall rentals, the establishment of business units, and the organization of social and educational activities.(2) Online strategies are still limited to the use of QRIS for donations and da'wah media, and have not yet extended to digital economic empowerment such as sharia-based marketplaces or online training platforms. In practice, mosques utilize several Islamic economic contracts, including ijarah, muḍarabah, and wakalah. The implementation of these empowerment programs faces several internal and external challenges. This study formulates six effective strategies to address these challenges. These findings are expected to serve as strategic recommendations for mosque administrators, government institutions, and the broader community in enhancing the role of mosques as centers of community economic empowerment.

This Community Service Program aims to strengthen the basic English language skills of children aged 5-12 in RW 03 Kalibaru, Cilincing, North Jakarta. Initial observations revealed low vocabulary mastery and a lack of confidence in communication among these children. With foreign language literacy rates for primary school-aged children in coastal North Jakarta at only 27.5%, non-formal educational intervention is crucial to support their school learning. As part of a university community service program (KKN), this initiative was carried out over three meetings with 30 children. The method used was Participatory Action Research (PAR), which emphasizes active collaboration between program facilitators and the community. The program's implementation included introducing basic materials such as the alphabet, numbers, colors, and vocabulary related to animals and family members, as well as practicing simple conversations like self-introductions and greetings. The learning methods applied were highly interactive, integrating educational games, songs, visualization, and role-playing. The evaluation, using pre-test and post-test instruments, showed a significant improvement in the participants' understanding. The average initial score increased sharply from 68.5 to 85.7, representing a 17.2-point or approximately 25% increase. This improvement proves the effectiveness of the interactive methods used in strengthening material mastery. Furthermore, the program successfully fostered an inclusive and enjoyable learning environment. A social change was observed in the form of increased self-confidence among the children when using English, a willingness to speak in front of their friends, and positive interactions among participants. Overall, this program not only succeeded in enhancing basic English skills but also fostered social transformation through increased confidence and positive interaction. Although challenges such as varying levels of understanding and limited learning media were encountered.

Providing education on how to wash hands properly is an important effort to increase awareness of clean and healthy living, especially for young children. Children at this age are in a very rapid developmental stage, so the information and habits taught are more easily absorbed and formed into daily behavior. However, children's awareness and understanding of the importance of hygiene, especially handwashing, is still relatively low. Therefore, health education is essential to instill good habits from an early age. Washing hands with soap is one of the Clean and Healthy Lifestyle Behaviors (PHBS) that is effective in preventing the spread of various types of diseases, especially diseases transmitted through hands, such as diarrhea, ARI, and skin infections. PHBS about handwashing must be a habit applied in daily life, both in the family, school, and community environment. This educational activity was carried out at St. Francis Xaverius Pineleng Catholic Kindergarten with the aim of increasing knowledge and forming handwashing behavior according to the six recommended handwashing steps. The implementation method included providing educational materials, showing a video song that teaches the six steps of handwashing, demonstrations by the implementer, and direct practice by the children with movements and songs. The results of the activity showed an increase in children's knowledge and skills in washing their hands properly. The children demonstrated enthusiasm and active participation during the educational process. It is hoped that teachers and parents will continue to encourage children to practice hand hygiene to prevent illness and foster healthy lifestyles from an early age.
