This empirical descriptive case study explored the implementation of oxytocin massage to improve breast milk flow among post–Sectio Caesarea mothers in the Alamanda Ward of RSI PKU Muhammadiyah Pekajangan. Five participants were selected through purposive sampling based on predefined inclusion and exclusion criteria. Data were collected using structured observation sheets assessing lactation indicators, clinical responses, and implementation quality over three consecutive days. Findings indicate that oxytocin massage was associated with progressive stabilization of postoperative physiological conditions, enhanced maternal readiness for breastfeeding, and consistent clinical implementation aligned with institutional standard operating procedures. The integration of structured monitoring and complete documentation supported reliable evaluation of lactation outcomes within the case-study framework. The results highlight that effective implementation quality plays a crucial role in maximizing the neurohormonal mechanisms underlying milk ejection reflexes in post-surgical mothers. These findings support the incorporation of oxytocin massage as an evidence-informed, non-pharmacological nursing intervention to optimize lactation management in post–Sectio Caesarea care settings.

Abstract This study aims to develop the most optimal vacuum control system in a vacuum chamber in a thermal desalination process based on the principle of multi-effect distillation (MED). In this initial study, the method used is an experimental method by varying the feed water flow rate. To facilitate adjustment, a vacuum pump will be installed in each chamber and before entering each chamber, a connecting tank will also be installed to prevent steam from being directly sucked by the vacuum pump which will be controlled by a solenoid valve. The controller component uses a Wisner REX-CH102 and the DAQ system uses a Wellpro WP3084. A control mechanism will be built in each chamber to regulate pressure using data acquisition (DAQ). Test results show that the control system responds to pressure fluctuations caused by feed water injection dynamically, with a relatively small measurement deviation (<1.0%). The resulting vacuum pressure pattern resembles a sawtooth curve, which reflects the opening and closing cycles of the solenoid valve to stabilize the pressure. Following the successful development of the vacuum pressure control system, further research can proceed by integrating boiler steam flow to assess overall MED-based seawater distillation performance.

The phenomenon of quiet quitting has recently gained increasing attention in human resource management studies as it reflects a decline in work engagement without formal resignation. In the context of foundation-based educational organizations, teachers as professional workers face complex job demands, including academic, administrative, and emotional responsibilities. These conditions may influence teachers’ work behavior, particularly their tendency toward quiet quitting. This study aims to examine the effects of workload, job stress, and job satisfaction on quiet quitting among teachers at Foundation X. This research employed a quantitative approach using a survey method. The population consisted of all teachers at Foundation X, totaling 92 respondents; therefore, a census sampling technique was applied. Data were collected through an online questionnaire using a six-point Likert scale and analyzed using Structural Equation Modeling based on Partial Least Squares (SEM-PLS) with SmartPLS software. The results indicate that workload has a positive and significant effect on quiet quitting, job stress has a negative but insignificant effect on quiet quitting, and job satisfaction has a negative and significant effect on quiet quitting. Furthermore, workload, job stress, and job satisfaction simultaneously influence quiet quitting among teachers at Foundation X. These findings suggest that high job demands without adequate job resources may encourage teachers to limit their work engagement as an adaptive response. Therefore, managing workload proportionally and enhancing job satisfaction are crucial strategies to reduce quiet quitting tendencies in foundation-based educational institutions.

Non-communicable diseases (NCDs) remain a major public health challenge in rural areas due to low health literacy and limited access to healthcare services. This condition was also identified in Daenggune Village, Kinovaro Sub-district, Sigi Regency. This community service program aimed to improve community understanding of NCD prevention and to enhance elementary school students’ knowledge of Clean and Healthy Living Behavior (PHBS) through an integrative approach. The activities were conducted using a pre-experimental one-group pretest–posttest design, encompassing health counseling, practice-based PHBS education, group physical activities, and free health screenings. Knowledge improvement was analyzed using a paired t-test, supported by observations of participant engagement and responses. The results demonstrated increased community knowledge regarding NCDs and improved understanding of PHBS among elementary school students, accompanied by high levels of community participation. These findings indicate that an integrative, community-based approach is effective in strengthening health literacy and awareness in rural communities and may serve as a model for enhancing promotive and preventive health programs at the village level.

Warm compresses, exercise, Mozart therapy, and relaxation are non-pharmacological methods for relieving menstrual cramps, which typically occur in the lower abdomen but can also radiate to the lower back, waist, pelvis, upper thighs, and calves. Turmeric and palm sugar drink is a popular herbal remedy and has long been known to relieve menstrual cramps. This study aims to compare the effectiveness of herbal remedies for menstrual cramps made from palm sugar and turmeric in relieving symptoms experienced by female students at SMPN 31 Seimarang. With a total of 32 participants and data collected using a validated and reliable NRS (numerical rating scale) questionnaire, this study used a quantitative methodology with a pre-experimental approach and a single-group pretest-posttest design. The Wilcoxon test was used to analyze the data and analyze how the independent and dependent variables are related to each other. With a p-value of 0.000 (p <0.05), the study's negative findings indicate a decrease in pain levels after the intervention. Female students at SMPN 31 Semarang reported less menstrual pain after consuming a herbal concoction containing turmeric, tamarind, and palm sugar. This indicates that the intervention successfully reduced pain, and the difference was statistically significant. To reduce the use of harmful drugs and increase the use of safe, non-pharmacological alternatives, it is crucial for schools to play an active role in educating students about reproductive health, particularly regarding non-pharmacological treatments for menstrual pain.

The postpartum period following Sectio Caesarea is often accompanied by acute pain due to surgical incisions, which may interfere with mobilization, breastfeeding, and maternal recovery. Effective pain management is essential to prevent further complications and enhance maternal comfort. In addition to pharmacological therapy, non-pharmacological interventions such as Benson relaxation therapy can be implemented. This study aimed to evaluate the application of Benson relaxation therapy in reducing acute pain among postpartum Sectio Caesarea mothers.This study employed a case study design involving four postpartum Sectio Caesarea patients (Ny. R, Ny. A, Ny. Y, and Ny. S) treated in the Ayyub Ward of RS Roemani Muhammadiyah Semarang in 2026. Data were collected through comprehensive nursing assessments, pain intensity measurement using a numeric rating scale, observation of mobilization ability, and evaluation before and after intervention.The results showed that after regular implementation of Benson relaxation therapy, all patients experienced a gradual decrease in pain intensity (from scale 4–7 to ≤3), improved comfort, better breathing control, and increased ability to perform early mobilization. Consistent nursing education, therapeutic guidance, and family involvement supported the effectiveness of the intervention. It can be concluded that Benson relaxation therapy is an effective, safe, and easily applicable nursing intervention for reducing acute pain in postpartum Sectio Caesarea patients.

Background: Hypertension is a chronic disease that can increase the risk of serious complications, including heart disease and stroke. One non-pharmacological approach that can be used to manage the accompanying hypertension is the slow deep breathing technique. This technique aims to provide a relaxation effect, reduce blood pressure management, and help regulate blood pressure in hypertensive patients. Objective: This study aims to analyze the effectiveness of the application of slow deep breathing on blood pressure in elderly hypertension patients in the Kenanga Room of Limpung Hospital Method: This study used a descriptive method with a case study approach conducted in September 2025. Data were collected through blood pressure measurements before and after the intervention, and using a blood pressure management questionnaire. The intervention was carried out for three consecutive days, with repeated administration of the slow deep breathing technique. Results: The results showed that there was a significant decrease in blood pressure after the intervention. Before the intervention, the average blood pressure of respondents was high, with the highest value of 202/116 mmHg and the lowest 148/100 mmHg. After the intervention, blood pressure decreased gradually, with an average decrease of 6-15 mmHg. Conclusion: Slow deep breathing has been shown to be effective in lowering blood pressure levels in people with hypertension. This technique can be used as a complementary therapy in the management of hypertension in patients.

Arrhythmia detection using electrocardiogram (ECG) signals requires an appropriate segmentation strategy to optimally represent cardiac morphological information. Although time-based windowing is widely applied in automated detection systems, the impact of window size variation on classification performance has not been systematically investigated. This study aims to evaluate the influence of different window sizes on arrhythmia detection performance using the K-Nearest Neighbors (KNN) algorithm. The dataset consists of 48 records from the MIT-BIH Arrhythmia Database sampled at 360 Hz. ECG signals were preprocessed using a 0.5–50 Hz bandpass filter and segmented with window sizes of 180, 360, 720, and 1000 samples using 50% overlap. Time-domain statistical features were extracted and used as input to the classification model. Experimental results indicate that the 180-sample window achieved the best performance, with an accuracy of 89.58% and an F1-score of 83.27%. These findings suggest that shorter segmentation windows increase training data density and are more suitable for distance-based classifiers such as KNN. This study highlights that window size selection is a critical parameter in arrhythmia detection system design and should be aligned with the characteristics of the classification algorithm employed.

Low birth weight (LBW) infants are at risk of physiological disorders such as hypothermia, unstable oxygen saturation, and hemodynamic disorders due to limited adaptation to the environment outside the womb. This study aims to determine the effect of positioning and nesting on changes in body temperature, oxygen saturation, and heart rate in LBW infants. The method used was a descriptive case study with a one-group pretest–posttest approach on five LBW infants treated in the Perinatology Unit of Batang Regional General Hospital. The nesting and positioning interventions were administered for three consecutive days, with each session lasting 30 minutes. Physiological parameters were measured before and after the intervention using a digital thermometer, neonatal pulse oximeter, and stethoscope. The results showed an increase in average body temperature from 35.8°C to 36.6°C, oxygen saturation from 94.8% to 98.2%, and heart rate from 130.8 to 136.8 beats per minute within normal limits. It was concluded that positioning and nesting are effective as non-pharmacological therapies to support the physiological stability of LBW infants.
