ABSTRACT The maternal mortality rate (MMR) in Indonesia remains relatively high, with postpartum infection being one of the leading causes. The postpartum period is a critical phase during which physiological changes occur, increasing the risk of infection. However, the lack of adequate maternal health monitoring remains a challenge in the early detection of This study aims to implement health technology-based monitoring using wearable sensors (HRV sensor/smartwatc. and axillary thermometers to detect changes in maternal body temperature and heart rate variability during the postpartum period. A total of 20 postpartum mothers, aged 2-14 days, from Pagesangan Subdistrict, were monitored for seven days. The results showed that the majority of participants . %) were in good health. however, two participants . %) experienced an increase in body temperature above 38AC and unstable HRV, which are early indicators of postpartum infection. These participants were immediately provided with additional health education and referred to healthcare professionals for further examination. Meanwhile, the remaining participants continued to receive routine monitoring and education regarding postpartum infection prevention. The implementation of this community service program demonstrated that health technologybased monitoring is effective in detecting real-time health condition changes, allowing for faster medical interventions and increasing maternal awareness of postpartum health. The findings suggest that this method can serve as an innovative approach to reducing postpartum infection risks and improving maternal health quality. Further development and wider application of this approach in other regions are recommended to enhance postpartum care and maternal well-being. Keywords: Health Technology. Postpartum Infection.

According to the 2022 Indonesian Nutritional Status Survey (SSGI), the Journal of Community Engagement in Health https://jceh. ISSN: 2620-3758 . 2620-3766 . https://doi. org/10. 30994/jceh. Vol. 8 No 1. March 2025. Page. 38 - 44 MMR reaches approximately 189 per 100,000 live births. Most maternal deaths occur during the postpartum period, particularly within the first 24 hours to one week after delivery. The primary causes of postpartum maternal mortality include postpartum hemorrhage . -50%), postpartum infection . epsis puerperali. -20%), preeclampsia and eclampsia . -15%), pulmonary embolism, and other complications . %) (Kementerian Kesehatan RI, 2. Additionally, many postpartum mothers experience various health complications affecting their well-being and that of their newborns, including postpartum anemia, perineal wound infections, psychological disorders, and breastfeeding difficulties (SDKI, 2. The postpartum period, defined as the 42 days following childbirth, is crucial for maternal recovery and infant health (Prawirohardjo, 2. However, the lack of maternal awareness regarding postpartum care remains a significant challenge in Indonesia, increasing the risk of complications such as infections, hemorrhage, and other health disorders (Hayati, 2. Several factors contribute to the lack of awareness among postpartum mothers, including insufficient education and information, socio-cultural factors, limited access to healthcare services, and inadequate mental health awareness (Asa Bayuana, 2. In practice, postpartum maternal health monitoring is still limited to conventional examinations, which are not entirely effective in the early detection of complications. Conventional examinations primarily include blood pressure measurement, body temperature assessment, perineal wound inspection, and monitoring of postpartum bleeding and psychological conditions (Asa Bayuana, 2. Data from the Surabaya City Health Office indicate that many postpartum mothers fail to undergo postnatal health examinations according to recommended standards. Reports from Kebonsari Public Health Center in Pagesangan Subdistrict reveal that the number of postpartum mothers attending postnatal check-ups remains below the targeted levels (Kementerian Kesehatan RI, 2. This lack of awareness regarding postpartum danger signs, such as excessive bleeding, perineal wound infections, and breastfeeding difficulties, may lead to severe complications that increase maternal morbidity and mortality (WHO, 2. Several previous community service programs have been conducted to improve postpartum maternal health monitoring. A study by Handayani et al. focused on conventional postpartum monitoring methods such as home visits and health counseling, which increased maternal awareness but lacked real-time physiological monitoring. Another study by Nugroho et al. implemented mobile-based monitoring but did not integrate physiological parameters such as HRV and body temperature. Meanwhile, research by Sari et . used wearable health monitoring devices but was limited to a small-scale hospital Compared to these studies, the current program integrates wearable sensor technology with community-based monitoring, allowing for real-time detection of postpartum complications and more effective early interventions. This approach provides a more comprehensive strategy for reducing postpartum infection risks and improving maternal health outcomes (Task Force of The European Society of Cardiology, 1. Therefore, educational interventions and health monitoring strategies are needed to enhance maternal awareness and promote optimal postpartum self-care. Implementing non-invasive biomarker-based monitoring methods, community-based education, and leveraging technology for maternal and infant health monitoring can systematically improve postpartum care services and reduce maternal complications and mortality rates (Bobak, 2. METHODS This community service initiative employed an educational and technology-based health monitoring approach, following these stages: The target population comprised all postpartum mothers aged 2-14 days in Pagesangan Subdistrict, with a total sample of 20 respondents.

Page. 38 - 44 Wearable sensor technology was used to monitor maternal body temperature for seven days using an axillary thermometer. A temperature above 38AC was considered an indication of potential postpartum infection. HRV (Heart Rate Variabilit. sensors in the form of smartwatches were utilized to continuously record heart rate fluctuations. Table 1.
