Abstract

Selecting an appropriate inventory management application is a challenge for business actors, especially SMEs, due to the variety of features, costs, and complexities offered. Manual selection is often carried out without a clear systematic approach and tends to be influenced by bias, resulting in suboptimal decisions. This study aims to integrate the Rank Order Centroid (ROC) and Additive Ratio Assessment (ARAS) approaches in developing a Decision Support System (DSS) to determine the best inventory management application. ROC is used to assign proportional weights to criteria based on priority ranking, while ARAS evaluates alternatives using these weights and relative utility values against the ideal solution. The developed system includes key features such as data management for criteria, alternatives, and values, as well as the ability to generate recommendations through alternative ranking. Based on a case study, the best alternative identified is Sortly: Inventory Simplified, with the highest utility score of 0.8627, followed by Housebook - Home Inventory (0.8528), inFlow Inventory (0.8336), and Inventory Stock Tracker (0.7056). Usability testing showed an average user acceptance rate of 91%, categorized as "Excellent". The main contribution of this research is the implementation of a practical and efficient combination of ROC and ARAS for selecting inventory management applications. The findings can be adopted by businesses to support more accurate and efficient decision-making.

Abstract

This study aims to analyze the reading comprehension of narrative texts among ninth-grade students at MTs Negeri 3 Kampar. According to the curriculum established by the Indonesian government, students are expected to comprehend various elements of narrative texts, including their generic structures and language features. This research employed a descriptive quantitative method, with data collected through a multiple-choice test consisting of 24 items. The test measured students’ abilities to identify factual information, main ideas, vocabulary meaning, references, inferences, orientations, complications, and resolutions. The findings reveal that students’ average reading comprehension score falls within the “Good” category, with a mean score of 80. Approximately 55% of students demonstrated strong ability in identifying factual information, and 64% were able to determine the main idea. However, some students experienced difficulties, particularly in identifying references and making inferences. These findings underscore the need for more effective instructional strategies and interventions to enhance students’ comprehension skills. It is expected that this research will offer valuable insights for educators in improving students’ understanding of narrative texts.

Background: Ethylene glycol (EG) is an antifreeze substance commonly used as an additive for syrup preparations. One of the detrimental effects caused by EG toxicity is acute renal failure (ARF) and death, assuming therapy and management are delayed. Presently, there are limited studies on toxicity of EG and therapy. Therefore, this study aimed to provide an overview of EG toxicity levels, clinical manifestations, arising reactions, and therapy management methods.Objectives: A narrative review design was employed with data collected from PubMed and Google Scholar. The strategy used keywords such as “ethylene glycol toxicity” and "acute renal" with the assistance of Boolean operators including AND and OR.Methods: The result showed that the minimum EG level for toxicity was at 22 mg/dL, followed by metabolic acidosis with an increased anion gap (>10mmol/L). Based on case reports from one experimental study, the clinical manifestations of patients experiencing EG poisoning included decreased consciousness, tachycardia, and coma, with ARF occurring after 24-72 hours.Results: Write study findings in this section.Conclusion: EG poisoning could cause kidney damage in the form of ARF and lead to death, assuming therapy was delayed. Presently, the most effective therapy for EG poisoning was fomepizole.

Abstract

Tulisan ini berfokus pada penerapan metode Debat didalam kelas bahasa Inggris sebagai bahasa asing. Metode yang diterapkan lebih bertujuan untuk memberi kompetensi linguistik daripada pengetahuan tentang debat itu sendiri. Karena tidak ada metode terbaik yang cocok untuk semua situasi belajar, metode ini dapat menjadi alternatif dalam mempelajari bahasa Inggris. Para ahli mendefinisikan metode ini sebagai metode belajar bahasa Inggris aktif. Hal ini dikarenakan metode ini benar-benar melibatkan seluruh siswa dalam situasi belajar. Metode ini menawarkan siswa untuk bekerja dan mengerti dengan lebih baik sendiri, menjadi lebih independen, bergerak, dan berfikir dengan keras namun menyenangkan. Ini sangat penting karena memberikan siswa kemampuan bahasa Inggris yang beraneka ragam, seperti mendengarkan, berbicara, megambil catatan, berfikir kritis dan sebagainya. Untuk tingkatan lanjutan, metode Debat dapat menjadi pemicu yang baik bagi siswa untuk memiliki kemampuan membaca bahasa Inggris yang lebih baik karena metode ini memotivasi siswa untuk membaca lebih banyak literatur dan sumber untuk mendapatkan lebih banyak referensi bagi alasan terhadap argumen dalam kelas Debat. Beberapa ahli yang lain mendefinisikan metode Debat sebagai metode inovatif.  Metode tersebut inovatif karena metode ini berkembang dari metode diskusi. Untuk membuat diskusi tradisional lebih bermakna (meaningful), Debat merupakan  pilihan yang baik dan layak untuk dicoba.

Abstract

Pada studi ini, nanokomposit ZnO/CuO telah berhasil disintesis dan dimodifikasi pada permukaan elektroda SPCE (Screen-Printed Carbon Electrode). Hasil karakterisasi menggunakan XRD, FTIR, dan SEM-EDX mengonfirmasi keberhasilan sintesis dengan struktur kristal CuO dan ZnO yang terdefinisi dengan baik tanpa adanya pengotor. Uji el-ektrokimia dengan teknik voltametri siklik (CV) menunjukkan bahwa SPCE termodifikasi ZnO/CuO memiliki arus oksidasi glukosa yang jauh lebih tinggi dibandingkan bare SPCE, dengan puncak oksidasi teramati pada +0,50 dan +0,63 V vs. Ag/AgCl. Peningkatan ini dikaitkan dengan sinergi CuO yang aktif secara katalitik dan ZnO yang berperan dalam meningkatkan konduktivitas serta stabilitas elektroda. Hasil penelitian ini membuktikan bahwa elektroda SPCE termodifikasi ZnO/CuO berpotensi dikembangkan sebagai sensor glukosa non-enzimatik yang sensitive dan selektif
