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.

an. Penelitian ini bertujuan untuk mengkaji bagaimana gaya hidup dan citra merek memengaruhi keputusan mahasiswa dalam membeli produk thrift. Secara teoritis, kajian ini berlandaskan pada konsep perilaku konsumen, dengan variabel gaya hidup (activity, interest, opinion) serta citra merek (recognition, reputation, affinity, loyalty) yang diasumsikan berperan dalam proses pengambilan keputusan pembelian. Penelitian ini menggunakan desain asosiatif kausal dan metodologi kuantitatif. Pengambilan sampel purposif digunakan untuk mengumpulkan data dengan membagikan kuesioner kepada 60 mahasiswa yang pernah berbelanja di toko barang bekas di Sukabumi. Menggunakan perangkat lunak SPSS versi 24, analisis meliputi uji-t dan uji-F, regresi linier berganda, uji validitas dan reliabilitas, serta uji asumsi klasik. Temuan menunjukkan bahwa citra merek dan faktor gaya hidup secara signifikan memengaruhi keputusan pembelian. Dengan koefisien determinasi (R²) sebesar 0,577, kedua faktor tersebut secara simultan memiliki pengaruh positif dan signifikan terhadap keputusan pembelian barang di toko barang bekas. Hal ini menunjukkan bahwa 57,7% keputusan belanja mahasiswa dipengaruhi oleh gaya hidup dan citra merek. Oleh karena itu, barang bekas tidak hanya menjadi pilihan yang lebih terjangkau, tetapi juga mencerminkan gaya hidup mahasiswa yang mengutamakan keberlanjutan dan identitas.
Abstract:This study aims to analyze the communication strategy employed by the NEI-DT Foundation in building community trust through a community-based healthcare service program in Tritunggal Hamlet, Banyuasin Regency, South Sumatra,…
tra, Indonesia. The study is motivated by the importance of organizational communication strategies in enhancing public participation and program legitimacy within rural communities characterized by limited access to information, geographical constraints, and community-oriented social structures. Adopting a constructivist paradigm, this research employs a qualitative approach using an intrinsic case study design. Data were collected through in-depth interviews, non-participant observation, and document analysis involving seven informants, including foundation representatives, community leaders, and program beneficiaries. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, encompassing data condensation, data display, and conclusion drawing. The findings reveal that the foundation’s communication strategy involves identifying community characteristics, developing simple and contextually relevant messages, utilizing a combination of digital and traditional communication channels, and engaging local leaders as communication intermediaries. Program information is disseminated through village heads, neighborhood leaders, women’s community groups (PKK), social media platforms such as WhatsApp and Facebook, and mosque loudspeaker announcements. The study further demonstrates that the communication pattern reflects the Two-Step Flow of Communication model, in which community leaders function as opinion leaders who mediate organizational messages before they reach the wider community. Community trust is cultivated through the social legitimacy of local leaders, interpersonal communication, direct experiences with program benefits, and the consistency of services provided by the foundation. The study concludes that the effectiveness of community-based organizational communication strategies in rural settings is determined not only by message content and media utilization but also by the organization’s ability to establish interpersonal relationships, adapt communication practices to local cultural contexts, and actively involve community leaders within the communication network. This research contributes to the advancement of community-based organizational communication studies by providing empirical insights into trust-building processes in rural community development programs

Abstract:This study analyzes the interpersonal language actions used by students in class interactions at SMP Negeri 5 Manuju with the Functional Systemic Linguistics (LSF) approach. This approach emphasizes the role of language…
as a tool to build social meaning and facilitate interaction in the context of learning. The purpose of the research is to understand how students use language to communicate, coordinate, and negotiate meaning in learning activities. The research method used is qualitative descriptive with data collection through direct observation of classroom interactions, in-depth interviews with teachers and students, and documentation in the form of recordings and field notes. Data analysis is carried out interactively through the stages of collection, reduction, presentation, and extraction of meaning from interpersonal utterances that appear in learning. The results showed that students' interpersonal language actions were realized through three types of mood clauses: interrogative, used to ask questions and ask for clarification; declarative, used to convey an opinion or information; and imperative, used to direct group work with mitigation to maintain social harmony. The function of this language act is not only to convey information, but also to build social relationships, organize group collaboration, and provide subtle approval or support. These findings provide an overview of how language plays a role in shaping communicative and collaborative interactions in the classroom.

t Java. Principals who are far from democratic values such as deliberation or expressing opinions, Public Junior High Schools in Merauke are less able to control subordinates. This study aims to analyze the implementation of quality-based democratic leadership by Public Junior High School principals in Merauke Regency and identify supporting and inhibiting factors. The method used in this study is a qualitative descriptive approach with primary data sources in the form of in-depth interviews, direct observation, and documentation in five Public Junior High Schools in Merauke, as well as secondary data in the form of archives and educational regulations. The results show that a quality-based democratic leadership style can create a collaborative work climate that improves teacher performance and the quality of educational services, if balanced with effective coordination, continuous motivation, and transparency in decision-making. However, obstacles were also found in the form of a lack of firmness of leaders in enforcing discipline, weak consistency in providing examples, and the influence of local culture that gives rise to personal sentiments. Supporting factors include active teacher involvement in school program planning, support from local government policies, and school accreditation that encourages quality improvement. The conclusion of this study is that democratic leadership of quality-oriented school principals is effectively implemented if accompanied by increased managerial competence, strengthening the role of the school principal as a motivator, and a commitment to transparency and professionalism.

Abstract:This study aims to analyze and identify how the news of "Former Chicken Cage Becomes School" represents the inequality of access to education with the framework of Norman Fairclough's critical discourse analysis. This study…
udy adopts a descriptive qualitative method using Norman Fairclough's critical discourse analysis (AWK) as the main framework. Data is collected through documentation and recording of news texts from relevant online media. Data analysis was carried out sequentially covering Fairclough's three dimensions: microstructural analysis (word choice, sentence structure, rhetorical strategy), mesostructural analysis (the practice of production and distribution of news texts), and macrostructural analysis (social and ideological relationships that underlie discourse). The results of this study reveal the complex representation of inequality in access to education through critical discourse analysis (AWK) on the news "Former Chicken Cage Becomes School" with the Norman Fairclough approach. Microstructurally, word choice and sentence structure build a narrative of struggle and implicit criticism of the system. At the mesostructural level, local MATAMAROS.COM strategic media frame this issue as an urgent social issue, including publication during National Education Day 2025 to maximize impact. Macrostructurally, the news reflects structural inequality due to geographical/economic marginalization, reinforces the ideology of "unsung heroes," and highlights the power imbalance. This descriptive qualitative research concludes that the news is a strong linguistic construct, aiming to mobilize public opinion on inequality in access to education, while reflecting the issue of unequal development and the role of actors in social justice

hen the intensity of the student movement increased in response to various public policy issues. The main purpose of this research is to uncover the practice of digital mainstream media representation of student actions and dissect the ideological power relations between state actors and civil society groups in the realm of media discourse. The approach used is Norman Fairclough's three-dimensional model of Critical Discourse Analysis (AWK), which includes analysis at three levels: textual structure (lexical and syntactic), discourse practice (the process of production and consumption of texts), and social practice (ideological and institutional context). Five news articles from Kompas.com were analyzed in depth as the main sample. The results of the study show that online media tends to frame student actions through dictionaries that reduce the meaning of their struggle, such as "chaos," "secured," and "not conducive," while prioritizing quotes from state officials or security forces. This disarticulation plays a role in strengthening the state's authority in shaping public opinion and shows the tendency of the media as a hegemonic agent. These findings emphasize the urgency of ideological awareness-based media literacy so that people are able to criticize and not passively accept media discourse.
