Abstract:The increasing volume of patient visits in primary healthcare facilities (such as community health centers and clinics) demands efficient resource management and scheduling systems. The inability to predict patient arrival…
al patterns often leads to long queues and suboptimal allocation of medical personnel. To overcome these issues, this study proposes the development of an intelligent framework based on Stacking Ensemble Learning to accurately classify and predict patient revisit frequency patterns. The proposed architecture integrates three heterogeneous base classification models (base learners), namely Logistic Regression (LR), Support Vector Machine (SVM) with non-linear Radial Basis Function (RBF) kernel projection, and Random Forest (RF). The probability predictions from these three base models are then combined into a secondary Logistic Regression based meta-learner to optimize the final decision and reduce the predictive bias of single models. Experiments were conducted using a dataset sourced from actual primary healthcare medical records, totaling 499 data entries. Given the highly imbalanced distribution of demographic data, the preprocessing stages were comprehensively designed, encompassing numerical scale feature standardization and the application of the SMOTE (Synthetic Minority Oversampling Technique) class balancing algorithm. Model testing was performed using a 5-fold stratified cross-validation scheme to ensure the robustness of the model's generalization. Comprehensive evaluation results proved that the Stacking Ensemble architecture achieved peak performance with an Accuracy of 88.4%, Precision of 85%, Recall of 90%, and an F1-Score of 0.88. Furthermore, curve analysis revealed an Area Under the Receiver Operating Characteristic (AUC-ROC) score of 0.961 and a Precision-Recall AUC of 0.95, consistently outperforming the capabilities of each individual baseline model. These findings confirm that combining hybrid machine learning models can produce highly stable and reliable predictions while minimizing false negative errors. This architecture holds massive potential for practical implementation as the foundation of a decision support system in managing operational services within primary healthcare facilities.
Abstract:Penelitian ini bertujuan untuk menganalisis orientasi percakapan, orientasi konformitas, serta pola komunikasi ibu dan anak pada keluarga ibu pekerja pabrik sumpit di Kampung Pameungpeuk, Desa Sukamanah, Kecamatan Rongga,…
, Kabupaten Bandung Barat berdasarkan teori Family Communication Patterns yang dikemukakan oleh Fitzpatrick dan Ritchie. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif. Subjek penelitian meliputi tiga keluarga ibu pekerja pabrik sumpit yang terdiri atas tiga ibu, tiga anak, tiga ayah, serta satu pemilik pabrik sebagai informan kunci. Data diperoleh melalui wawancara mendalam, observasi, dan dokumentasi, kemudian dianalisis dengan tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa ketiga keluarga memiliki orientasi percakapan yang tinggi, ditandai dengan komunikasi yang terbuka, kebiasaan berdiskusi, serta pemberian kesempatan kepada anak untuk menyampaikan pendapat. Orientasi konformitas juga tergolong tinggi karena orang tua tetap menanamkan nilai, aturan, dan tanggung jawab kepada anak, meskipun tetap memberikan ruang untuk berdiskusi. Berdasarkan kedua orientasi tersebut, pola komunikasi yang terbentuk cenderung mengarah pada pola komunikasi konsensual. Penelitian ini menyimpulkan bahwa pekerjaan ibu sebagai buruh pabrik sumpit tidak mengurangi kualitas komunikasi dalam keluarga. Keterbatasan waktu justru mendorong ibu memanfaatkan waktu bersama secara lebih efektif sehingga hubungan dengan anak tetap terjalin dengan baik. Temuan penelitian ini diharapkan dapat memberikan kontribusi terhadap pengembangan kajian komunikasi keluarga, khususnya pada keluarga ibu pekerja sektor informal di wilayah pedesaan.
Abstract:The growth of the gig economy in Indonesia has triggered significant transformations in the traditional labour structure. This study aims to analyse the impact of the gig economy on workers' employment patterns, income,…
and social protection using a literature review method. The results of the analysis show that the gig economy offers flexibility and new employment opportunities but also increases income uncertainty and widens the social protection gap between gig and traditional workers. In addition, there is a skills disruption that requires increased digital literacy and worker adaptability. This research recommends the need for labour regulation reform, strengthening portable social security systems, and expanding access to digital training so that the gig economy can provide inclusive and sustainable benefits for the entire Indonesian workforce.
Abstract:This study investigates the strategic role of Islamic journalistic communication in promoting fraternal compassion and fostering bilateral harmony between Indonesia and Singapore. In an era shaped by digital polarization…
and cultural fragmentation, ethical journalism becomes crucial in constructing inclusive narratives and supporting peaceful cross-border relations. The objective of this research is to identify how Islamic values particularly the principle of rahmatan lil-‘alamin (mercy to all creation) inform journalistic practices that contribute to intercultural understanding and regional diplomacy. Using a qualitative, library-based approach, the study examines comparative media discourse from Indonesia and Singapore to highlight patterns of ethical communication that emphasize compassion, responsibility, and soft power engagement. The results reveal that Islamic journalistic communication offers a transformative model to counter stereotypes, foster mutual respect, and enhance transnational solidarity. This study contributes to the broader academic discourse on Islamic media ethics, intercultural dialogue, and religion-based peacebuilding by proposing a theoretical framework for ethical Islamic journalism applicable in other multicultural societies across Southeast Asia.
Abstract:This study aims to analyze the impact of Fear of Missing Out (FoMO) on consumer behavior among adolescent Shopee users in Jakarta. Shopee, as a popular e-commerce platform in Indonesia, has influenced consumption patterns,…
s, especially among female students, through attractive promotions such as discounts and free shipping. FoMO, which is the fear of missing out on popular opportunities or trends, can drive individuals to make impulsive purchases, even when these purchases do not meet their basic needs. This research employs a quantitative method using FoMO and consumer behavior measurement tools that have been validated. The results of the analysis indicate that FoMO has a positive influence on consumer behavior, with an influence rate of 59.6%. These findings suggest that higher levels of FoMO are associated with a greater likelihood of engaging in consumptive behavior, such as buying items merely to avoid missing out on discounts. This study reinforces the understanding that psychological factors such as FoMO can influence irrational purchasing decisions among adolescent e-commerce users.
Abstract:This study investigates the influence of Financial Literacy on Consumptive Behavior among students, with PayLater Usage as an intervening variable and Self-Control as a moderating variable. The rapid adoption of digital…
credit services, such as PayLater, has reshaped consumption patterns, particularly among young users, by promoting convenience and flexible payment options. This research aims to understand how financial literacy and self-control interact to influence students’ consumption behavior through PayLater usage. Using Structural Equation Modeling (SEM) with a sample of 100 students from the Faculty of Economics and Business at Universitas Teknologi Sumbawa, the study finds that Financial Literacy has a positive influence on both PayLater Usage and Consumptive Behavior. Interestingly, while financial literacy is generally expected to mitigate consumptive tendencies, it indirectly contributes to impulsive spending by encouraging the use of PayLater. PayLater Usage is identified as an intervening variable that strengthens the relationship between Financial Literacy and Consumptive Behavior, highlighting the role of convenience and perceived purchasing power in promoting consumption. Moreover, Self-Control negatively moderates the relationship between PayLater Usage and Consumptive Behavior, indicating that students with high self-control are less likely to exhibit impulsive spending despite using PayLater.
Abstract:This study aims to explore strategies and techniques to overcome verbal communication barriers in an academic context, particularly between lecturers and students during the completion of final projects at the State Islamic…
mic University of North Sumatra (UIN-SU). Using interactive communication theory and uncertainty reduction theory, this research provides a framework for understanding and addressing these barriers. The research method employed is a qualitative approach with data collection techniques including in-depth interviews, direct observation, and related document studies. Data were analyzed using content analysis to identify patterns and trends in verbal communication. Triangulation, peer debriefing, and external checks were used to ensure data validity. The research results indicate that the communication model implemented by lecturers greatly influences the effectiveness of guidance and the quality of students' final projects. Communication barriers are often caused by misunderstandings in written communication and differences in expectations. Proposed solutions include effective communication training for lecturers, the use of written communication guidelines, and regular group and individual guidance sessions. The integration of communication technology such as e-learning platforms and online collaboration tools is also suggested to enhance the communication process. By understanding the dynamics of verbal communication and overcoming existing barriers, this research aims to improve the quality of academic guidance and student outcomes, as well as prepare them for communication challenges in the professional world. This study is relevant not only in the academic context but also has broad practical implications.
