Abstract

Purpose: Accurate detection of paddy leaf diseases is essential to ensure optimal crop yield and effective disease management. Methods/Study design/approach: In this study, we propose a hybrid deep learning model combining Convolutional Neural Networks (CNN), Long Short-Term Memory (LSTM), and an Attention mechanism for paddy leaf disease classification using the Paddy Doctor dataset. The CNN layers extract spatial features from leaf images, the LSTM captures contextual relationships between these features, and the Attention mechanism emphasizes the most relevant patterns for accurate classification. Result/Findings: Experimental results show that the proposed CNN+LSTM+Attention model achieves 95.5% accuracy, 98.12% precision, 98.3% recall, and 0.994 macro AUC, outperforming a simple CNN-3 layer while offering competitive performance compared to state-of-the-art architectures such as ResNet34 and Xception. Novelty/Originality/Value: These results demonstrate that the proposed model is highly effective in detecting paddy leaf diseases with minimal false negatives, providing a reliable and practical solution for automated paddy disease monitoring systems

Abstract

This study aims to analyze the impact of implementing wireless security protocols WPA2-PSK and WPA3-SAE on handover performance in 5 GHz networks. Efficient handover is crucial to maintaining seamless connectivity and quality of service in WiFi networks, especially on the 5 GHz frequency band widely used for high bandwidth applications. The research method involves testing and measuring handover performance parameters such as handover latency, connection handover success rate, and signal stability for both security protocols. The analysis results indicate that although WPA3-SAE offers significant security improvements compared to WPA2-PSK, there are differences in handover performance that need to be considered. WPA3-SAE tends to cause slightly higher handover latency due to its more complex authentication process but still provides good connection stability. Conversely, WPA2-PSK show lower handover latency but with a lower level of security. These findings provide important insights for network administrators in selecting a security protocol that balances security needs and handover performance to optimize user experience on 5 GHz networks.

Abstract

Mental health is a vital aspect of human well-being, yet often neglected. Recent studies report a rise in depression, anxiety, and stress among adolescents, especially post-COVID-19. Machine learning has emerged as a powerful tool for predicting mental health conditions. This study employs the XGBoost Regressor using a regression-based ML approach to predict mental health high school students. To enhance accuracy, hyperparameter optimization is conducted using a Genetic Algorithm (GA) to identify the optimal parameter set. The baseline model achieved an MSE of 0.3698, RMSE of 0.6081, and MAPE of 14.09%. After GA optimization, performance improved to an MSE of 0.3092 (16.4% reduction), RMSE of 0.5560 (8.6% reduction), and MAPE of 12.88% (8.6% reduction). These results demonstrate the model's effectiveness for early mental health screening in educational settings, enabling timely interventions by school counselors and healthcare providers.

Abstract

Savings and loan cooperatives are strategic microfinance institutions facing challenges in managing loan reminder processes. XYZ Savings and Loan Cooperative operates manual reminder processes without standard documentation, creating risks of human error and operational inefficiency. This study aims to design Business Process Model and Notation (BPMN) to model and standardize loan reminder processes at XYZ Savings and Loan Cooperative. The research employed a qualitative approach with descriptive analytical methods. Data collection was conducted through direct observation for one month, interviews with the Secretary Department Cooperative Employee, and internal document studies. Business process analysis was performed to understand existing workflows, then modeled into BPMN elements using Bizagi Modeler software. Model validation was conducted through structured questionnaires with 20 validation aspects. BPMN model was successfully designed with two main scenarios namely Friday reminder process as the main process and Monday reminder process with follow-up mechanisms. The model involves three main actors (Cooperative Members, Cooperative Employees, and Cooperative Head) with clear swimlane divisions. The process starts from attendance checking, WhatsApp messaging, phone calls, to coordination for direct visit scheduling. Validation shows perfect conformity of 100% from 20 evaluated aspects. The BPMN model successfully transformed manual processes without documentation into structured and standardized visualization. The study concludes that BPMN implementation can effectively standardize previously manual and undocumented loan reminder processes, producing standard documentation that can be implemented for procedure standardization and new employee literacy, thereby improving operational effectiveness and reducing human error risks in cooperative loan reminder processes.

Abstract

Tomat merupakan produk pertanian penting di banyak negara, termasuk Indonesia. Namun, penyakit daun tomat dapat berdampak signifikan pada hasil panen dan kualitas tanaman. Oleh karena itu, deteksi dini penyakit sangat penting untuk meningkatkan hasil panen. Dalam penelitian ini, kami menerapkan transfer learning  menggunakan arsitektur ResNet-50 untuk klasifikasi penyakit daun tomat berbasis Convolutional Neural Network (CNN). Dataset yang digunakan berisi 2902 gambar daun tomat yang mencakup 10 kategori termasuk daun sehat dan sembilan jenis penyakit. Proses penelitian meliputi akuisisi data, preprocessing citra dengan augmentasi untuk meningkatkan keragaman dataset, dan pengembangan model menggunakan ResNet-50 untuk ekstraksi fitur. Hasil evaluasi model menunjukkan akurasi keseluruhan sebesar 99%, dengan rata-rata presisi dan perolehan lebih besar dari 0,97 untuk sebagian besar kategori penyakit. Kategori Two-Spotted Spider Mite menunjukkan performa terbaik dengan nilai presisi, recall, dan skor F1 sebesar 1,00. Meskipun terdapat sedikit kesalahan klasifikasi pada beberapa kategori seperti Tomato Yellow Leaf Curl Virus, model tersebut tetap menunjukkan kinerja yang baik dalam mendeteksi keriting daun tomat. Penelitian ini diharapkan dapat memberikan kontribusi terhadap pengembangan sistem deteksi penyakit tanaman berbasis teknologi pengolahan citra yang lebih efisien dan akurat.
