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.

eceived through vision. It includes the recognition of shapes, colors, sizes, patterns, and visual relationships, which are essential for children’s learning readiness. This study aims to improve the visual perceptual abilities of children aged 5–6 years at TK Sarantau Sasurambi through smartboard-based learning. The research employed a Classroom Action Research (CAR) method conducted in several cycles, namely planning, action, observation, and reflection. The research subjects were children aged 5–6 years. The research instruments included observation sheets of visual perceptual abilities (visual discrimination, visual memory, matching, sequencing, spatial relations, and eye–hand coordination), observation sheets on the use of the smartboard, and field notes. The results showed an improvement in visual perceptual abilities from the pre-cycle to Cycle I and Cycle II. Children’s mastery in the pre-cycle reached only 45%, increased to 65% in Cycle I, and reached 88% in Cycle II. The use of smartboards proved effective as it offers interactive and engaging visual learning experiences and facilitates children’s direct manipulation of objects. Therefore, smartboard-based learning is highly effective in improving the visual perceptual abilities of children aged 5–6 years.

tivity aims to improve literacy and practice of Islamic parenting through the Quranic Parent School program at the Merpati Early Childhood Education Post in Kutawaluya District. The program is designed to build synergy between schools and families in supporting the social-emotional and spiritual development of early childhood. The method used is a community-based participatory approach with stages of needs identification, joint action planning, parenting class implementation, and periodic reflection and evaluation. Activities are implemented through workshops, reflective discussions, simulations of Islamic parenting practices, and the establishment of a parent forum as a forum for program sustainability. The results of the activity indicate an increase in parents' understanding of the concepts of fitrah (natural nature) and adab (good manners), changes in communication patterns to be more empathetic, and consistent habits of worship and restrictions on gadgets at home. Further impacts are seen in increased discipline and emotional regulation of children at school and the formation of a Quranic family learning community. The implications of this activity confirm that strengthening Islamic parenting through the Quranic Parent School model is effective in encouraging family-based social transformation and has the potential to be replicated in other PIAUD institutions with similar characteristics.
Abstract:Cocoa is a strategic commodity in Southeast Aceh Regency, but farmer productivity and income remain low due to limited implementation of Good Agricultural Practices (GAP) and poor access to price information. This community…
ity service activity aims to improve farmers' capacity through an integrated approach that combines improving cocoa cultivation knowledge, strengthening the implementation of GAP, and utilizing real-time cocoa price information applications. The activity was carried out in December 2025 through stages of socialization, technical training, field demonstrations, introduction to price applications, as well as mentoring and evaluation. The results of the activity showed an increase in farmers' knowledge levels from low to medium to high, especially in terms of price information. Initial improvements in GAP adoption were reflected in pruning, fertilization, garden sanitation, pest control, and harvesting and post-harvesting practices that were more in line with standards. Access to price information shifted from dependence on middlemen to the use of applications and market comparisons, which increased farmers' independence in determining the time of sale. The price range difference between farmers and market references confirms that limited information weakens farmers' bargaining position. Overall, the integrated approach has proven relevant in improving farming efficiency and strengthening the basis for increasing cocoa farmers' income, although the sustainability of the impact requires continued assistance and strengthening of farmer institutions.
