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.

This qualitative case study investigated the factors and impacts of English language learning anxiety among students at SMP Muhammadiyah Tanjungpinang. The research focused on students from the 7th, 8th, and 9th grades during the academic year 2024/2025. A total of 32 students across all grade levels were involved in the study. The researchers initially conducted classroom observations to identify students who exhibited signs of anxiety during English lessons. Based on these observations, eleven students were selected as participants for semi-structured interviews and more detailed classroom observations. The research aimed to explore how anxiety manifests in the classroom and how it affects students' language acquisition in a unique socio-educational environment. The data collected through interviews and observations were analyzed qualitatively by interpreting students’ responses and behavioral patterns in class. The findings revealed that three primary types of language anxiety—Communication Apprehension, Test Anxiety, and Fear of Negative Evaluation—were commonly experienced by the students. These forms of anxiety were often interconnected, compounding the emotional barriers students faced in English learning. One of the key contributing factors was the students’ fear of peer ridicule, especially within a tightly bonded student community. Many of the participants were affiliated with orphanages connected to the school, which created a unique emotional and social environment. This setting, while supportive in many ways, also contributed to heightened sensitivity to peer judgment and a strong fear of making mistakes. As a result, the affective filter among these students was notably high, significantly hindering their willingness to participate and ultimately affecting their English language acquisition.

This corpus-based study explores the acquisition patterns of English modal verbs by Indonesian EFL (English as a Foreign Language) learners through a comprehensive analysis of learner language data. The study utilizes a specialized learner corpus consisting of 2.5 million words drawn from both written and spoken productions of 450 Indonesian learners, covering various proficiency levels. The research focuses on examining the frequency patterns, semantic distributions, and error types associated with modal verb usage across the learner corpus. The study employs a combination of quantitative corpus linguistic methods and qualitative error analysis to uncover developmental trends and persistent difficulties in acquiring English modals. The findings highlight a significant underuse of epistemic modality, which expresses degrees of certainty, and an overreliance on core modals like "can," "will," and "must." Additionally, learners systematically avoid more complex modal constructions that are semantically nuanced and less frequent in their linguistic output. The analysis also reveals notable cross-linguistic influences from Indonesian, particularly in the areas of politeness marking and the expression of certainty. These interference patterns suggest that Indonesian learners may transfer modal expressions from their native language, leading to specific errors in the usage of English modals. Based on the findings, the study proposes a usage-based pedagogical framework that integrates corpus-informed instruction with explicit semantic mapping of modal meanings. This framework encourages teachers to address modal verb acquisition by emphasizing frequency-based approaches, contrastive semantic analysis, and corpus-driven awareness-raising activities. The research suggests that by focusing on the form-meaning-function relationships of modals in authentic contexts, learners can better understand and produce English modals accurately and appropriately. The findings have significant implications for enhancing modal verb instruction in EFL classrooms, especially for Indonesian learners.

Background: Stunting remains a serious public health issue in Indonesia, particularly in rural areas such as Ambasea Village, Laeya Sub-district, South Konawe Regency. Stunting, or chronic growth failure in children due to prolonged malnutrition, generally occurs during the first 1,000 days of life. In Ambasea Village, this problem is exacerbated by irregular eating patterns among toddlers, consumption of low-nutrient foods, and poor hygiene behaviors. Toddlers frequently consume unhealthy snacks, reject main meals such as rice and side dishes, and rarely wash their hands with soap before eating or after using the toilet. Furthermore, limited access to basic sanitation—such as the lack of proper latrines and adequate wastewater disposal systems (SPAL)—also contributes to the high risk of infections that disrupt nutrient absorption, increasing the likelihood of stunting in children. Objective: This study aims to describe the environmental health conditions contributing to the incidence of stunting among children aged 0–2 years in Ambasea Village. Methods: The research used an observational analytic method with a quantitative cross-sectional design. The study involved 54 toddlers identified as stunted. Data were collected through structured interviews with parents or caregivers and direct observation of the household and surrounding environmental conditions. Results: The results showed that 66.5% of households did not have access to proper latrines, and 70% lacked adequate wastewater disposal systems. However, 87% had access to clean water, and 85% of respondents demonstrated good handwashing behavior. Conclusion: The environmental health conditions in Ambasea Village reveal ongoing challenges related to latrine ownership and wastewater management. Although clean water access is relatively good and hygiene practices among residents are fairly positive, improving sanitation infrastructure remains crucial. Enhancing these conditions is expected to significantly reduce the risk of stunting among toddlers in the area. Collaborative efforts involving local government, health workers, and the community are essential to create a healthier environment for early childhood development.

The nutritional status of elementary school children serves as a vital indicator of their overall growth, development, and future health outcomes. Poor nutritional status, whether in the form of undernutrition or overweight, can lead to a range of health and academic performance issues. This study aimed to assess the nutritional status of Grade 4A students at SD 064981 Cempaka Raya using anthropometric measurements and to examine the association between snacking habits and nutritional categories. A descriptive quantitative research design was employed, utilizing a total sampling approach involving all 20 students in the class. Data collection consisted of direct height and weight measurements conducted according to standardized procedures. The data were then analyzed using the WHO Anthro Plus software to classify nutritional status into undernourished, normal, overweight, and obese categories. Additionally, information on students’ snacking habits during school hours was obtained through structured questionnaires. The results indicated that 25% of students were undernourished, 50% had normal nutritional status, 20% were overweight, and 5% were obese. Bivariate analysis using the Chi-Square test demonstrated a statistically significant relationship (p < 0.001) between snacking behavior and nutritional status. Specifically, all students who reported frequent consumption of snacks at school were classified as overweight or obese, whereas those who did not engage in frequent snacking predominantly fell within the undernourished or normal categories. These findings highlight the potential role of unhealthy snacking patterns in contributing to excessive weight gain among school-age children. Based on the results, it is recommended that nutrition education programs be implemented for both students and parents, coupled with stricter regulations on the availability and sale of high-calorie snack foods within the school environment. Such measures may serve as preventive strategies to promote healthy growth, maintain optimal nutritional status, and reduce the risk of non-communicable diseases later in life.

The existence of Final Waste Processing Sites (TPA) in urban areas often presents a dilemma between the need for waste management infrastructure and its environmental and social impacts on surrounding communities. This study aims to examine the impact of the TPA Terjun in Medan City on patterns of land use change and the socioeconomic conditions of nearby residents. The method used is quantitative, involving a survey of 150 respondents, and multiple linear regression analysis to test the influence of two independent variables namely, the characteristics of the TPA and public perception and response on community perceptions of environmental impacts. The results indicate that both independent variables have a significant simultaneous effect on public perception, with a model significance value of 0.022. Partially, the physical characteristics of the TPA have a significantly positive influence, while community perceptions and responses also contribute meaningfully. However, the low coefficient of determination (R² = 0.009) suggests that many other factors outside the model also influence perceptions of environmental impact. This study highlights the importance of a holistic approach in spatial planning and urban environmental management, particularly in relation to public facilities such as TPAs. Community participation, infrastructure quality, and zoning certainty are crucial factors in maintaining the balance between the functional needs of the city and the desired quality of the microenvironment.

The development of digital technology has brought about significant changes in people's transaction patterns, particularly with the increasing use of online platforms for buying and selling. This phenomenon provides convenience for consumers and merchants, but is also accompanied by a high rate of online fraud experienced by both consumers and merchants. This fraud can take the form of fraudulent transactions, goods not received, or identity fraud. Low public legal literacy regarding rights and obligations in digital transactions is one of the main causes of weak legal protection for fraud victims. Many consumers and merchants are unaware of their rights and the legal procedures to take when experiencing fraud. This community service activity aims to increase the legal understanding of the public, especially online merchants and consumers, regarding digital consumer protection and legal fraud handling mechanisms. The activity implementation methods included interactive legal counseling, distribution of closed-ended questionnaires, case study simulations, Q&A discussions on legal issues, and light consultations. A total of 60 respondents, consisting of 30 merchants and 30 consumers, participated in the closed-ended questionnaire. The results showed that the majority of participants did not fully understand their rights in digital transactions and were unaware of the legal procedures to take when experiencing fraud. Despite this, participant interest in legal education was very high, with over 75% stating they wanted further legal assistance. This activity is expected to provide the public with better insight into their rights and obligations in digital transactions, as well as raise awareness of the importance of legal protection in the digital age. This is expected to make the public more vigilant and protected from potential online fraud in the future. Furthermore, increased legal literacy is expected to create a safer and more trustworthy digital transaction ecosystem for all parties.

This study aims to analyze the electrical energy consumption of a bench-type drilling machine, RYU RDB 13, by varying machining parameters in the form of spindle speed and feed rate. Electrical energy is a critical aspect of production efficiency in the manufacturing industry, particularly in machining processes that require continuous power consumption throughout the cutting operation. The material used in this study is aluminum 6061, chosen for its lightweight, corrosion resistance, and wide application in the automotive and aerospace industries. The drilling process was carried out using three spindle speed variations: 620 rpm, 920 rpm, and 1280 rpm, along with three feed rate variations: 0.04 mm/rev, 0.08 mm/rev, and 0.1 mm/rev. Current and voltage were measured using a digital wattmeter in real-time, and energy consumption was calculated in wattseconds (Ws) using power calculation formulas. The results indicate that increasing the feed rate and spindle speed leads to higher instantaneous power consumption. However, total energy consumption tends to decrease at higher speed and feed combinations due to shorter machining times. The optimal parameter combination was found at a feed rate of 0.1 mm/rev and a spindle speed of 1280 rpm, which resulted in the lowest energy consumption of 387 Ws and the fastest drilling time. This demonstrates that selecting the right machining parameters not only improves energy efficiency but also maintains or enhances productivity. The observed power consumption pattern typically shows a sharp increase at the beginning of the drilling process, a stable phase during the main cutting stage, and a rapid decrease towards the end of the cut. These findings contribute to a better understanding of the relationship between machining parameters and energy efficiency, serving as a basis for developing sustainable production strategies in the manufacturing sector that prioritize energy savings and cost reduction.

This research explores the influence of customer satisfaction on the financial performance of Perumda Tirtanadi, with a particular focus on the digital service system as a moderating factor. The study is driven by the growing urgency for digital innovation in public service sectors, particularly in the wake of the COVID-19 pandemic, which significantly altered customer engagement patterns. A quantitative method is adopted, employing Partial Least Squares–Structural Equation Modeling (PLS-SEM) using the SmartPLS 4 software to process the collected data. The analysis demonstrates that both customer satisfaction and digital services have independent and significant positive effects on financial outcomes. However, the interaction between these two variables does not show a statistically significant moderating effect. These findings underline the value of digital infrastructure as a strategic internal resource that supports financial growth. Nevertheless, the minimal moderating impact suggests that a portion of customers either lack access or sufficient skills to effectively utilize the available digital platforms. This study adds to the current body of knowledge by examining the interplay between digital transformation and customer satisfaction in shaping financial performance, framed through the Resource-Based View (RBV) theory. The research suggests that improving digital literacy and promoting better adoption of digital tools among customers is essential to fully capitalize on the benefits of technological advancement. Furthermore, it highlights the need for continuous training and support to ensure that all customers can engage with digital services effectively, thereby enhancing overall satisfaction and financial performance. By addressing these gaps, organizations can foster a more inclusive digital environment that benefits both the customers and the service providers.
