Science lessons in primary school significantly contribute to the early development of logical, scientific and systematic reasoning skills.   However, learning science can be challenging, especially when it comes to understanding abstract concepts and cause-and-effect interactions.   This is due to the fact that, as per Piaget's theory, primary school students are still in the concrete operational stage and have limited cognitive growth. Data regarding abstraction ability and causal reasoning in the context of science education were collected from various scientific sources using the literature review research methodology.  According to the research findings, STEAM integration, project-based learning strategies such as Project Based Learning (PBL), and the use of real and visual aids can help lower learning barriers. Successful learning is also influenced by the teacher's role as facilitator, which involves presenting the material in a relevant and contextualized way and fostering a positive learning environment. Real-world examples and exceptional examples, such as the use of worksheets based on cause-and-effect relationships and basic experiments, demonstrate how useful these strategies are for improving abstract thinking and understanding of cause-and-effect relationships. Developing innovative teaching methods based on practical, exploratory and integrative experiments is essential for maximizing the scientific understanding of primary school students.

This study aims to determine the relationship between family social support and the discipline of 4-5-year-old children at Pembina State Kindergarten. The study used a quantitative method with a descriptive correlational approach. A sample of 14 parents was selected using a purposive sampling technique. Data were obtained through a five-level Likert scale questionnaire and analyzed using the Pearson Product-Moment correlation test. The results showed that children's discipline was in the very high category at 93.5%, while family social support was also in the very high category at 94.9%. However, the correlation test showed an r value of –0.14, indicating a very weak and insignificant relationship between family social support and children's discipline. This finding indicates that, despite high family support, other factors such as role models and school habits likely have a greater influence on the development of children's discipline. This study emphasizes the importance of collaboration between families and educational institutions in supporting the development of discipline in early childhood.

Information security is an essential aspect of digital communication, particularly in the exchange of text-based messages through open networks. Messages transmitted without protection are vulnerable to interception and unauthorized modification. One classical cryptographic technique that remains relevant as a foundational learning tool is the Caesar Cipher algorithm. This study aims to implement the Caesar Cipher algorithm for message encryption and decryption and to analyze its effectiveness and security level. The research method employed is a descriptive approach through literature review and a case study by applying character-shift techniques to text messages. The results indicate that the Caesar Cipher algorithm successfully transforms plaintext into ciphertext and restores it back to its original form through the decryption process. Although the algorithm is simple and easy to implement, it has significant limitations in terms of security due to its small key space and vulnerability to brute-force attacks. Therefore, Caesar Cipher is not suitable for protecting sensitive data but remains valuable as an introductory model for understanding basic cryptographic concepts.

This study examines the economic dynamics experienced by migrant women through the perspective of abstract painting as a medium for personal and social reflection. The study uses a qualitative method with an artistic research approach, which departs from the researcher's personal experience as a migrant woman facing increasingly complex economic realities. The rising cost of living, financial constraints, and intertwined academic demands create pressure not only on material aspects, but also on psychological, emotional, and mental conditions. This situation demands adaptation strategies, resilience, and the ability to survive in the face of uncertainty in migrant areas. The dynamics of these experiences are then translated into visual language through an abstract expressionist approach utilizing mixed media techniques. Dynamic line elements, contrasting colors, bubble textures, and layers of material are used as symbols of the tension, struggle, and economic instability experienced by the subjects. The research findings show that abstract painting functions not only as a means of personal expression, but also as a medium for social reflection that records and articulates the experiences of migrant women who are often marginalized. This research contributes to the enrichment of contemporary art discourse, particularly in presenting visual narratives that voice economic issues and women's life experiences in a critical and reflective manner.

Drug storage is not only carried out in health facilities but can also be done independently by the community that consumes drugs, either as an emergency supply or leftover medication from previous use. Drug storage is often done without paying attention to the condition after the packaging is opened or understanding the drug's usage limit/Beyond Use Date (BUD). The community generally only looks at the expiration date/Expired Date (ED) on the drug packaging as a reference for safe drug use, and does not understand the safe usage limit for drugs after the primary packaging is opened. The purpose of this community service is to evaluate the community's knowledge and practices regarding the implementation of BUD/ED, as well as to provide education. This community service was carried out with an educational approach involving 21 people in Rejosari Village. This activity was carried out by distributing questionnaires to the community about the knowledge and practice of BUD/ED daily, then continued with the delivery of education using posters. The results of this activity indicate that the community has good knowledge of ED and BUD, but has not yet implemented ED and BUD in the storage and use of drugs independently.
