Anemia during pregnancy is a significant maternal health issue with serious impacts on maternal and perinatal outcomes, including complications such as severe preeclampsia, postpartum hemorrhage, and low birth weight (LBW), all of which contribute to increased morbidity and mortality rates. This literature review aims to analyze the clinical impacts of pregnancy anemia, related complications, and effective management strategies based on the latest scientific evidence (2020-2024). The study examines the relationship between anemia and preeclampsia, LBW, and postpartum hemorrhage, as well as the importance of nutritional fulfillment in prevention and management. Five research articles from indexed journals were collected from the Scopus database, with inclusion criteria of studies with clear designs, focusing on pregnancy anemia, and published in Indonesian or English. The analysis results show that pregnancy anemia is a predisposing factor for preeclampsia through mechanisms such as placental hypoxia and oxidative stress. Anemia is also closely related to an increased incidence of LBW and postpartum hemorrhage, particularly due to lower hemoglobin reserves and uterine contractility issues. Adequate nutritional fulfillment is influenced by socioeconomic barriers, supplementation side effects, and lack of family support. Anemia management requires a comprehensive approach, including routine screening, prophylactic supplementation, nutritional education, and effective referral systems for complex cases. Prevention through early detection and timely intervention is crucial in reducing maternal and perinatal morbidity.

The employee leave application information system is a digital solution designed to simplify the process of submitting, approving, and managing leave within an institution. This internship project resulted in the development of a system called SiCuti, which was built using the Laravel framework with a MySQL database. The system provides two main roles: employees and administrators/supervisors. Employees can apply for leave according to their entitlements, such as annual leave with a maximum of 12 working days, maternity leave for 3 months, pilgrimage leave (Hajj) which can be taken once during their service period, as well as special leave for important reasons such as marriage or the death of an immediate family member, typically lasting 1–3 days. When applying, employees may also upload supporting documents and monitor the status of their applications through the leave status menu.Administrators or supervisors have broader authority, including reviewing the list of leave requests, approving or rejecting applications, and managing employee leave quotas to ensure compliance with regulations. In addition, administrators can track the complete leave history of employees through an integrated dashboard. This feature supports faster, more transparent, and accountable decision-making processes.The results of local testing indicate that SiCuti has the potential to increase efficiency in administrative leave processes that were previously carried out manually, making them faster, more transparent, and more structured. The interactive dashboard design also facilitates monitoring from both employees and administrators. With the implementation of SiCuti, it is expected that the leave management process can reduce the risk of human error, ensure data accuracy, and support transparency and accountability in human resource management once the system is fully deployed within the institution.

Social Studies (IPS) learning in elementary schools plays a crucial role in fostering students’ social awareness, which includes understanding social values, developing empathy, and participating responsibly in community life. However, in practice, Social Studies learning often remains theoretical and textbook-centered, making students’ learning experiences less meaningful and disconnected from real-life contexts. To address this issue, utilizing the surrounding environment as a learning resource offers an effective alternative by bringing real social situations into the learning process. This study aims to analyze the concepts, implementation, and impact of environmental utilization on enhancing elementary students’ social awareness. The research employed a Systematic Literature Review (SLR) method by reviewing relevant scholarly articles obtained from national and international databases such as Garuda, Google Scholar, and ScienceDirect, using the keywords “environment as a learning resource in Social Studies” and “students’ social awareness.” The findings reveal that the use of the surrounding environment as a learning resource promotes students’ critical thinking, empathy, and social concern through contextual and participatory learning experiences. Moreover, teachers play a pivotal role in designing project-based and field-observation activities that strengthen the internalization of social values. Therefore, Social Studies learning that integrates environmental resources is proven to be effective in shaping students’ social character from an early age and supports the realization of holistic, active, and life-oriented education.
