The rapid growth of digital wallet usage has generated a large volume of user reviews that can be utilized to evaluate service quality. This study aims to improve the accuracy of digital wallet user sentiment classification using a Stacking Ensemble Machine Learning approach that combines Support Vector Machine (SVM), Multinomial Naïve Bayes (MNB), and AdaBoost with Logistic Regression as the meta-learner. User reviews were processed through text preprocessing stages, including case folding, text cleaning, tokenization, stopword removal, stemming, and TF-IDF feature weighting. Synthetic Minority Over-sampling Technique (SMOTE) was employed to address class imbalance, while model performance was evaluated using 5-Fold Cross-Validation. The experimental results show that the proposed Stacking Ensemble model achieved an average accuracy of 80.55%, outperforming the individual base learners. Furthermore, evaluations based on the Confusion Matrix, Classification Report, and Receiver Operating Characteristic (ROC) Curve demonstrated improvements in precision, recall, F1-score, and the model's discriminative capability. These findings indicate that the proposed Stacking Ensemble Machine Learning approach is effective in improving the accuracy of digital wallet user sentiment classification and can serve as a reliable tool for supporting service quality evaluation based on user opinions.

ts of SDN Telang 2 in the 2026/2027 academic year. The study used a quantitative approach with the Pre-Experimental Design method and One Group Pretest-Posttest Design. The research subjects were 17 students. Data collection techniques were carried out through tests, observations, and documentation. The research instrument was a multiple-choice test given before and after treatment. Data were analyzed using descriptive statistics and paired sample t-test. The results showed that the average pretest score of 68.82 increased to 79.41 in the posttest, with an increase of 10.59 points. The results of the paired sample t-test showed a significance value (2-tailed) of 0.000 <0.05, so H₀ was rejected and H₁ was accepted. These findings indicate that the use of Google Earth media through the CTL model has a significant effect on the learning outcomes of social studies on natural phenomena material. The integration of Google Earth and CTL provides a more contextual, interactive, and meaningful learning experience, helping students understand the concept of natural features more concretely. Therefore, Google Earth, through the CTL model, can be used as an alternative media and effective learning model to improve social studies learning outcomes in elementary schools.

Abstract:This study aims to design the warehouse tata letak at PT MIKRON PRESISI INDONESIA that experiences post-relocation irregularities in production facilities, along with adjustments to the area area and available rental costs.…
ts. The absence of a racking system and clear classification of goods has caused the storage, retrieval, and work safety processes to not run efficiently. The research approach uses a qualitative descriptive method by collecting data through field observations, interviews, and documentation. The tata letak design was carried out by implementing the Activity Relationship Chart (ARC) and Activity Relationship Diagram (ARD) methods, then tested through simulations using FlexSim software with two operator scenarios. The simulation results showed that the proposed alternative tata letak design was able to improve the workflow by grouping goods into seven categories and arranging shelves based on the level of proximity of activities. However, the utilization rate of operators is still relatively low, namely 17.65% and 19.78%, due to the periodic pattern of goods arrival and efficient search times due to a more structured storage system. These findings indicate opportunities for human resource optimization through reducing the number of operators or adjusting workloads. The resulting tata letak design makes a practical contribution to improving warehouse space efficiency and operations, and can be used as a reference for applications for companies with similar characteristics.

Abstract:This study aims to examine the effect of implementing the Sam'iyah Syafawiyah method based on a communicative approach on students' self-confidence in speaking Arabic through a library research approach. The study employs…
s a qualitative method with a systematic literature review, analyzing and synthesizing scientific sources including books, international and national journals, articles, proceedings, and relevant research findings. Data sources were obtained from scientific databases such as Google Scholar, JSTOR, ScienceDirect, ERIC, and national digital repositories. The findings consistently demonstrate that the Sam'iyah Syafawiyah method integrated with the communicative approach has a positive and significant influence on students' self-confidence in speaking Arabic. This effect operates through four main mechanisms: (1) repetitive drilling builds mastery experience; (2) native speaker audio models provide vicarious experience; (3) the communicative approach reduces affective filters; and (4) intensive practice promotes automaticity in Arabic speech production. This study concludes that the integration of both methods constitutes an effective and recommended pedagogical strategy for improving self-confidence in Arabic speaking.
Penelitian ini bertujuan untuk mengkaji pengaruh penerapan metode Sam'iyah Syafawiyah berbasis pendekatan komunikatif terhadap kepercayaan diri peserta didik dalam berbicara bahasa Arab melalui pendekatan library research (studi kepustakaan). Penelitian menggunakan metode kualitatif dengan kajian literatur sistematis, yakni menganalisis dan mensintesis berbagai sumber ilmiah berupa buku, jurnal nasional dan internasional, artikel, prosiding, dan hasil penelitian yang relevan. Sumber data diperoleh dari berbagai basis data ilmiah seperti Google Scholar, JSTOR, ScienceDirect, ERIC, dan repositori digital nasional. Hasil kajian secara konsisten menunjukkan bahwa metode Sam'iyah Syafawiyah yang diintegrasikan dengan pendekatan komunikatif memberikan pengaruh positif dan signifikan terhadap kepercayaan diri peserta didik dalam berbicara bahasa Arab. Pengaruh ini bekerja melalui empat mekanisme utama: (1) latihan drill berulang membangun mastery experience; (2) model audio native speaker memberikan vicarious experience; (3) pendekatan komunikatif menurunkan filter afektif; dan (4) latihan intensif mendorong otomatisasi produksi ujaran bahasa Arab. Penelitian ini menyimpulkan bahwa integrasi kedua metode tersebut merupakan strategi pedagogis yang efektif dan direkomendasikan untuk meningkatkan kepercayaan diri berbicara bahasa Arab.

improving the quality of education today. The process of integrating Powtoon learning media with a sense of responsibility in Gen Z students requires a comprehensive effort, considering that the assessment indicators for this attitude are crucial for learners in the modern era. Gen Z students (born 1997-2012) are digital natives who are pragmatic, creative, and highly dependent on technology for learning and personal branding. They favor visual-interactive methods, care about mental health/the environment, and focus on practical career outcomes (side hustles), but are prone to distraction and anxiety. Meanwhile, types of student attitude assessments generally include direct observation by lecturers, self-assessment, peer assessment, and daily journal entries. Aspects assessed include discipline, responsibility, honesty, cooperation, politeness, and initiative. This technique often uses a Likert scale or descriptive rubric. Therefore, it is crucial to pay attention to these items in the learning process at university. Powtoon is a web-based online animation and presentation creation platform that allows users to create engaging visual content, such as explainer videos, without requiring advanced graphic design skills. This application uses drag-and-drop features, ready-to-use templates, animated characters, and is supported by AI-based tools. This research uses a descriptive method, namely a research approach that aims to describe, explain, or map the characteristics of a phenomenon, situation, or population systematically, factually, and accurately based on data collected during the study. The results show the successful integration of Powtoon learning media with the responsible attitude of Gen Z students, evidenced by the existence of an orderly, understandable learning process and a high quality of understanding.
