Abstract

Palang Merah Indonesia (PMI) berperan penting dalam layanan kemanusiaan, namun sistem administrasi manual sering menimbulkan keterlambatan informasi, pengelolaan data kurang efisien, dan respons darurat yang lambat. Untuk mengatasi hal tersebut, penelitian ini bertujuan mengembangkan sistem web admin layanan terpadu PMI Provinsi Kepulauan Bangka Belitung sebagai solusi digital guna meningkatkan efektivitas pengelolaan data dan koordinasi internal. Metode yang digunakan adalah Agile Scrum melalui tahapan scope, product backlog, design, dan sprint execution. Hasil pengembangan menghasilkan fitur login multilevel, dashboard statistik, manajemen donor dan stok darah, validasi laporan bencana, verifikasi ambulans, serta integrasi panggilan via WhatsApp. Berdasarkan pengujian User Acceptance Test (UAT) dengan responden petugas PMI, sistem memperoleh skor 82,8% dan dinyatakan layak digunakan. Dengan demikian, sistem ini mampu meningkatkan kualitas administrasi, mempercepat validasi layanan, serta memperkuat peran PMI dalam pelayanan kemanusiaan di Provinsi Kepulauan Bangka Belitung.

Abstract

Drowsiness poses significant risks in safety-critical activities such as driving, industrial operations, and online learning. While advanced deep learning models (e.g., CNN-LSTM hybrids) achieve high accuracy in driver drowsiness detection, they often require substantial computational resources, limiting deployment on embedded or resource-constrained devices. This study addresses the research gap in lightweight, real-time, non-invasive drowsiness detection by developing an embeddable library using YOLOv12, an attention-centric single-stage detector known for balancing speed and accuracy. The model was trained on a custom dataset of 2312 video frame sequences (1011 "awake" and 1301 "drowsy" states, captured from varied angles under consistent lighting), augmented with standard techniques (e.g., brightness/contrast adjustments, flips, and rotations) to enhance generalization. It was evaluated through 80 real-time trials across multiple subjects. Performance metrics include accuracy of 93%, precision of 0.94, recall of 0.91, and F1-score of 0.93. The system detects drowsiness via facial bounding boxes followed by state classification (integrating eye/mouth aspect ratios) in real time. The main contribution is a proof-of-concept YOLOv12-based approach for non-invasive drowsiness monitoring, offering faster inference suitable for embedded applications (e.g., vehicle systems, meeting tools, or industrial safety) compared to heavier hybrid models. Limitations include some remaining sensitivity to extreme lighting/angles and dataset scale; future work will expand datasets, incorporate multi-modal cues, and further test robustness in diverse real-world conditions.

Abstract

Detecting rotten apples is critical in postharvest quality sorting, as spoiled fruit can accelerate overall decay, shorten shelf life, and lower market value. This study introduces a real-time, edge-deployable object detection method using YOLOv12 to differentiate between fresh and rotten apples in RGB images. The dataset included 2,312 annotated images, with 1,011 fresh apples and 1,301 rotten apples, split into training, validation, and testing sets with an 80:10:10 stratified ratio. To enhance model generalization, data augmentation techniques such as mosaic augmentation, horizontal flipping, rotation, scaling, HSV color jitter, and mixup were applied. The YOLOv12s model was trained with an input resolution of 640 × 640 and evaluated using accuracy, precision, recall, and F1-score. The results from the confusion matrix showed that the model achieved an accuracy of 0.93, precision of 0.91, recall of 0.89, and F1-score of 0.90, indicating that YOLOv12 offers a lightweight and effective framework for rapid apple quality assessment. The primary contribution of this work lies in integrating an attention-focused YOLOv12 detector into a postharvest apple sorting workflow, accompanied by quantitative performance evaluation and robustness analysis under challenging visual conditions.

Abstract

Penelitian ini mengembangkan sistem klasifikasi sampah real-time untuk sampah organik, anorganik, dan bahan berbahaya beracun (B3) di Jalan Timah Sungailiat, Bangka Belitung, Indonesia menggunakan YOLOv11 untuk mengatasi pencemaran lingkungan akibat pengelolaan sampah yang tidak tepat. Dataset khusus sebanyak 5.000 gambar yang seimbang pada kondisi siang, senja, dan malam dikumpulkan untuk melatih YOLOv11 sehingga mampu menangani variasi pencahayaan. Metodologi meliputi pra-pemrosesan (ubah ukuran 640×640 piksel, normalisasi, augmentasi data), pelatihan YOLOv11 pada dataset seimbang, serta evaluasi menggunakan metrik mean Average Precision (mAP@0.5), presisi, recall, dan F1-score. Sistem mencapai mAP@0.5 sebesar 70%, presisi 69%, recall 70%, dan F1-score 0,70 dengan kecepatan 43 frame per detik (FPS) serta 102 GFLOPs sehingga dapat dijalankan pada GPU kelas menengah. Meskipun akurasi masih moderat karena variasi pencahayaan dan oklusi, kerangka kerja ini menawarkan solusi hemat biaya dan skalabel untuk pengelolaan sampah kota pintar, mengurangi tenaga sorting manual serta mendukung inisiatif daur ulang. Perbaikan mendatang akan fokus pada peningkatan performa malam hari dan penanganan.
