This study investigates the effect of the Team Word-Webbing technique on reading comprehension among tenth-grade students at MAN Koto Baru, Dharmasraya. Reading comprehension is critical for language acquisition and academic success, as it encompasses the ability to extract and interpret meaning from text. Despite its importance, many students struggle with reading comprehension due to various factors including limited vocabulary and insufficient engagement. To address these issues, the study employed a quantitative experimental design, using a quasi-experimental approach with an experimental group and a control group. The research involved a pre-test and post-test assessment to measure reading comprehension levels before and after the implementation of the Team Word-Webbing technique. The experimental group was taught using this technique, which involves organizing ideas visually to enhance understanding, while the control group received traditional instruction. The sample consisted of two classes selected through purposive sampling, with data analyzed using t-tests to compare outcomes. Results indicated that the Team Word-Webbing technique significantly improved reading comprehension compared to conventional methods. The experimental group demonstrated higher post-test scores, with statistical analysis revealing a significant difference (p < 0.05). This suggests that Team Word-Webbing enhances students' ability to understand and retain reading material by facilitating better organization of ideas and active engagement. In conclusion, the study supports the effectiveness of Team Word-Webbing as an instructional strategy to improve reading comprehension. This technique not only aids in comprehension but also promotes active learning and student interaction, making it a valuable tool for educators aiming to enhance reading skills in the classroom.

The Internet of Things (IoT) is an innovative technology that makes our environment smarter, with IoT devices as an integral part of home automation. Smart home systems are becoming increasingly popular as an IoT service in the home that connects via a network. Due to the security weakness of many devices, the malware is targeting IoT devices. After being infected with malicious attacks on smart devices, they act like bots that the intruders can control. Machine learning methods can assist in improving the attack detection process for these devices. However, the irrelevant features raise the computation time as well as affect the detection accuracy in the processing with many features. We proposed a machine learning-based IoT security framework using feature correlation. The feature extraction scheme, one-hot feature encoding, correlation feature selection, and attack detection implement an active detection mechanism. The results show that the implemented framework is not only for effective detection but also for lightweight performance. The proposed system outperforms the results with the selected features, which have almost 100% detection accuracy. It is also approved that the proposed system using CART is more suitable in terms of processing time and detection accuracy.

The increasing use of conventional medical supplies has led to significant environmental challenges due to waste accumulation and the chemical exposure risks faced by healthcare workers. Despite ongoing efforts to adopt environmentally friendly materials, there is a lack of comprehensive studies that combine Life-Cycle Assessment (LCA) with direct monitoring of worker exposure. This study aims to compare the environmental and health impacts of biodegradable versus conventional medical supplies by assessing their life-cycle stages, energy consumption, carbon footprint, and hazardous exposure risks. A novel comparative approach was adopted, integrating LCA to evaluate raw material extraction, production, usage, and disposal processes, alongside monitoring the occupational exposure to chemical residues from medical supplies. The results indicate that biodegradable medical supplies reduce environmental footprint by approximately 40%, lower energy consumption, and generate less waste compared to conventional plastics. Additionally, the study shows that biodegradable materials pose a significantly reduced risk of chemical exposure to healthcare workers, offering a safer alternative. However, biodegradable materials present limitations, such as availability, durability, and higher initial costs, which need to be addressed for widespread implementation. The findings emphasize the importance of integrating sustainable practices in healthcare settings, offering actionable insights for hospital management and regulatory bodies. Future research is recommended to further explore the cost-effectiveness of biodegradable materials, conduct large-scale trials, and investigate alternative material types. This study contributes to the growing body of knowledge on environmental sustainability and occupational safety in healthcare, providing a valuable framework for future policy and operational decisions.
