Abstract

Introduction: Cross-platform sentiment analysis for Indonesian language presents significant challenges when adapting models from general applications to specialized domains. Domain Adversarial Neural Networks (DANN) offer promising solutions for transfer learning, yet their effectiveness for Indonesian language remains largely unexplored, particularly under extreme class imbalance conditions common in trading platforms. Methods: This study investigates DANN effectiveness for transferring sentiment analysis knowledge from four strategically selected source domains to TradingView trading platform. The research utilizes 5,990 Indonesian reviews after preprocessing from an initial 6,000 samples, with source domains showing 66.5% positive sentiment while target domain exhibits 85.1% positive sentiment, creating an 18.7% distribution gap. Four experimental approaches were compared with statistical validation across multiple random initializations: Source-Only training, Multi-Domain training, Limited Target training, and DANN implementation. Results: DANN demonstrates stable cross-platform adaptation, achieving 87.77% ± 0.97% accuracy with consistent performance across initializations, outperforming Source-Only baseline (87.10% ± 0.84%) and Multi-Domain approach (86.98% ± 0.64%). While Limited Target baseline achieves higher accuracy (88.10% ± 2.23%), its high variance poses deployment risks. A-distance analysis reveals substantial domain gaps (193.00 ± 1.06), with DANN's adversarial training achieving modest domain separation reduction (72.90% ± 8.81% domain discrimination accuracy). Conclusions: This research contributes the first systematic evaluation of DANN for Indonesian cross-platform sentiment analysis, demonstrating that deployment consistency outweighs peak accuracy for production environments. The findings provide practical value for Indonesian fintech startups requiring robust sentiment analysis with limited labeled data. Future work should explore multi-target adaptation and optimization strategies for diverse Indonesian business domains

Abstract

Background: Waste mismanagement remains a critical issue in Indonesian campuses, where ineffective segregation and collection practices contribute to environmental pollution. Smart technologies offer opportunities to improve waste handling efficiency and monitoring in university environments. Methods: This study developed a smart waste bin prototype that integrates Internet of Things (IoT) sensors, machine learning–based image classification (MobileNetV2 with TensorFlow Lite), GPS tracking, and LoRa communication. The system was designed to classify three types of waste—plastic bottles, snack packaging, and cans—while enabling fill-level monitoring, automated sorting, and real-time location reporting. Results: Experimental results showed strong classification accuracy for plastic bottles (100%), but lower performance for snack packaging (53–80%) and cans (40–67%), especially in low-light conditions or with darker materials. The overall real-time testing accuracy reached 45.1%. LoRa communication provided long-range connectivity but was affected by electromagnetic interference, while GPS tracking was reliable in open areas but inconsistent indoors. Conclusions: The prototype demonstrates the feasibility of integrating AI and IoT for scalable campus waste management. Despite environmental and hardware limitations, it offers a modular framework that can be refined with improved lighting, EMI shielding, and enhanced datasets. This research contributes a practical model for smart campus initiatives and supports the adoption of sustainable waste management practices in higher education environments.

Abstract

This study develops a drug recommendation system using multilabel classification with the Decision Tree algorithm based on patient complaint and diagnosis data from electronic medical records. The dataset consists of patient visit records from a community health center in Pangkajene and Kepulauan Regency and is transformed using multi-hot encoding. Model performance is evaluated under three dataset scenarios (N=500, N=800, and N=1000) using multilabel metrics, including Micro-F1, Samples-F1, Hamming Loss, Jaccard Similarity, Hit@5, Precision@K, and Recall@K. The best Decision Tree model achieved a Micro-F1 score of 0.292, Samples-F1 of 0.281, and Hit@5 of 0.690 on the N=1000 dataset scenario. Bootstrap validation with 1000 iterations indicates relatively stable performance, with narrow confidence intervals across evaluation metrics. These results show that the multilabel Decision Tree model is capable of capturing relationships between patient complaints, diagnoses, and drug therapies while maintaining an interpretable decision structure

Abstract

Electronic medical records (EMR) are health information systems used to improve the efficiency of patient data management and the quality of healthcare services in healthcare facilities. However, several problems have been found, such as network disruptions or errors, double workloads, and suboptimal user satisfaction levels. This study aims to analyze the level of satisfaction and use of electronic medical records and to determine the relationship between satisfaction and system use at the Tamamaung Community Health Center in Makassar City and the Community Health Center Technical Implementation Unit (UPTD) in North Kolaka Regency. The study used a quantitative approach with a cross-sectional design. Respondents in this study were 55 healthcare workers who used EMR selected using a full sampling technique (Full Sampling). Satisfaction analysis was conducted using the End User Computing Satisfaction (EUCS) and Technology Acceptance Model (TAM) methods. Analysis of the relationship between satisfaction and system use was conducted using the Spearman Rank Correlation test. The results showed that all EUCS and TAM variables were in the "High" category. The correlation test results showed a correlation coefficient of 0.463 with a significance value of 0.000 (p <0.05), which indicates a significant and very strong relationship between satisfaction and use of the EMR system. The conclusion of this study shows that the higher the level of satisfaction, the higher the level of use of the RME system.

Abstract

This study aims to analyze the performance of various ensemble machine learning methods, such as Adaboost, Bagging, and Stacking, in the context of skin cancer classification using the skin cancer MNIST dataset. We also evaluate the impact of handling dataset imbalance on the classification model’s performance by applying imbalanced data methods such as random under sampling (RUS), random over sampling (ROS), synthetic minority over-sampling technique (SMOTE), and synthetic minority over-sampling technique with edited nearest neighbor (SMOTEENN). The research findings indicate that Adaboost is effective in addressing data imbalance, while imbalanced data methods can significantly improve accuracy. However, the selection of imbalanced data methods should be carefully tailored to the dataset characteristics and clinical objectives. In conclusion, addressing data imbalance can enhance skin cancer classification accuracy, with Adaboost being an exception that shows a decrease in accuracy after applying imbalanced data methods.

Abstract

Media sosial seperti Twitter (X) menghasilkan data opini publik dalam jumlah besar yang dapat dimanfaatkan untuk analisis sentimen. Namun, perbedaan konteks antar topik atau hashtag sering menyebabkan terjadinya domain shift yang dapat menurunkan performa model klasifikasi. Penelitian ini bertujuan untuk menganalisis performa algoritma Naïve Bayes dan K-Nearest Neighbors (KNN) dalam skenario cross-domain menggunakan dua representasi fitur, yaitu TF-IDF dan FastText. Dataset diperoleh dari hashtag #MakanBergiziGratis sebagai domain sumber dan #Danantara sebagai domain target. Metode yang digunakan meliputi preprocessing teks, ekstraksi fitur, pemodelan, serta evaluasi menggunakan accuracy, precision, recall, dan F1-score. Hasil penelitian menunjukkan bahwa kedua model memiliki performa tinggi pada internal test dengan accuracy sebesar 0.94. Namun, pada pengujian lintas domain, Naïve Bayes dengan TF-IDF menunjukkan performa yang lebih stabil dengan accuracy sebesar 0.75, sedangkan KNN dengan FastText mengalami penurunan signifikan, terutama pada kelas negatif dengan nilai F1-score sebesar 0.00. Temuan ini menunjukkan bahwa pemilihan algoritma dan representasi fitur sangat mempengaruhi kemampuan generalisasi model dalam menghadapi domain shift
