Delivery delays pose a major challenge in the e-commerce industry, often leading to decreased customer satisfaction and negatively impacting business operations. In this study, the XGBoost (Extreme Gradient Boosting) algorithm is applied to predict delivery delays based on a dataset containing 96,476 records. These records include various features relevant to the delivery process, such as shipping distance, carrier performance, and order characteristics. The model achieves a high overall accuracy of 93.24%, indicating strong general performance. In particular, XGBoost demonstrates excellent results in predicting on-time deliveries, achieving a precision of 93% and a recall of 100%. However, the model struggles to correctly identify delayed deliveries. The recall for delayed deliveries is 0%, and the F1-score is extremely low at 0.01. This significant discrepancy reveals a critical limitation in the model's performance — the inability to detect minority class cases (delayed deliveries) due to class imbalance within the dataset. The results highlight the importance of addressing data imbalance in predictive modeling for delivery outcomes. When the dataset is dominated by on-time delivery records, the model tends to be biased toward that class, failing to learn the patterns associated with delays. To improve performance, the study recommends integrating class balancing techniques such as SMOTE (Synthetic Minority Oversampling Technique) to generate synthetic samples of the minority class. Additionally, the use of alternative evaluation metrics beyond accuracy — such as precision, recall, and F1-score for each class — is suggested to provide a more comprehensive understanding of model effectiveness. Overall, the study provides valuable insights into the complexities of predicting delivery delays and outlines practical strategies for enhancing future models in e-commerce logistics analytics.

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.

Infant growth and development are crucial issues that require serious attention, particularly during the early childhood phase, which is crucial for a child's future development. The golden age of infants is the most sensitive period to various forms of stimulation that influence their motor, sensory, cognitive, and emotional development. However, not all parents, especially mothers, fully understand the importance of appropriate and safe stimulation in supporting infant growth and development. One form of stimulation that is relatively easy to perform, has no side effects, and can be applied independently at home is gentle touch therapy. Gentle Touch Therapy is a complementary therapy method that involves gentle, affectionate touch on the baby's body, aimed at stimulating the nervous system, strengthening the emotional bond between mother and child, and increasing comfort and relaxation in the baby. Several studies have shown that this gentle touch can improve sleep quality, accelerate weight gain, relieve stress, and encourage infant neuromotor and socio-emotional development. This community service activity was carried out as an effort to increase mothers' awareness and skills in providing stimulation through gentle touch. The activity was carried out at the Andina Independent Midwife Practice (PMB), Palembang City, in June 2025. The main target of this activity was mothers with babies aged 0–12 months. The implementation method included providing education through interactive lectures, demonstrations of touch therapy techniques by health professionals, and direct practice by mothers accompanied by facilitators. The results of the activity showed a significant increase in mothers' understanding of the importance of growth and development stimulation, especially through gentle touch therapy. The participants showed high enthusiasm in participating in the activity and were able to practice gentle touch techniques correctly and confidently.

This research focuses on exploring the mathematical reasoning abilities of Madrasah Aliyah students in solving problems that integrate mathematical concepts with the Islamic science of faraidh (inheritance law), specifically within the topic of fractions. The study employs a qualitative approach with a case study design and was conducted among 11th-grade students enrolled in the Religious Program at MA Raudlatul Ulum Putri. Data collection techniques included written tests, semi-structured interviews, and classroom observations, focusing on three selected students who represented high, moderate, and low levels of mathematical ability. The analysis centers on several key indicators of mathematical reasoning: identifying problems, formulating hypotheses, presenting logical arguments, and drawing conclusions. The results show that most students fall into the moderate reasoning category, while a smaller number are categorized as high or low. Students in the high category demonstrate a strong capacity to approach problems systematically and accurately, combining mathematical logic with a proper understanding of Sharia-based inheritance rules. In contrast, students in the low category struggle with interpreting problem contexts and executing fraction calculations correctly, which indicates gaps in both conceptual understanding and application skills. These findings underscore the importance of contextual and integrative learning, particularly the combination of mathematics with Islamic values, to enhance deeper comprehension. By embedding religious relevance into mathematical instruction—especially through real-life contexts such as inheritance laws—educators can support the development of more meaningful reasoning abilities. The study suggests that integrating mathematics and Islamic teachings can significantly benefit student learning outcomes and foster stronger conceptual foundations.

Students' understanding of the concept of motion of objects on inclined planes still shows obstacles, especially when applied in real practice. This study aims to see the extent to which students understand the concept through simple experiments and questionnaires. The main focus of the study was on the results of the practicum, where the block slid faster on a smooth plane (an average of 1.25 seconds) than on a rough plane (an average of 1.61 seconds). This time difference reflects the effect of friction on the motion of objects, but some students were unable to explain the difference correctly. This indicates that there are still misconceptions in understanding the concepts of force and motion. Meanwhile, the results of the questionnaire only reinforced that most students felt the need for direct practice to understand this material. Thus, a practice-based learning approach is very important to strengthen students' conceptual understanding in Basic Physics courses.
