Abstract

Penelitian ini membandingkan efektivitas metode kendali Proportional-Integral-Derivative (PID) dan Linear Quadratic Regulator (LQR) dalam meredam ayunan beban (sway) pada sistem gantry crane dua dimensi. Dengan simulasi MATLAB menggunakan variasi beban 0,1 hingga 1,3 kg, hasil menunjukkan bahwa kendali LQR mampu menjaga kestabilan posisi troli dengan waktu naik (rise time) antara 1,56 hingga 1,96 detik dan overshoot rendah sekitar 2,66%–3,24%, serta berhasil mengurangi overshoot ayunan beban dari 37,41% menjadi 28,18%. Sebaliknya, kendali PID meskipun menunjukkan rise time dan overshoot lebih kecil secara numerik, mengalami ketidakstabilan pada grafik respons posisi yang mengindikasikan divergensi sistem secara fisik. Temuan ini menegaskan keunggulan LQR dalam mengendalikan gantry crane dengan dinamika kompleks dan variasi beban, sehingga lebih cocok untuk aplikasi industri yang menuntut kestabilan dan keamanan tinggi.

Abstract

The increasing volume of organic waste in campuses or households demands innovative solutions for waste management and classification. This study proposes an automated classification system based on deep learning using the YOLOv5s algorithm to detect 14 categories of inorganic waste in real-time. The dataset consists of over 3.500 labeled images, annotated via Makesense.ai and augmented using Roboflow. The model was trained on Google Collaboratory for 100 epochs using the YOLOv5s architecture and evaluated based on precision, recall, F1-score, and mean Average Precision (mAP). Training result show mAP@0.5 approaching 100% and mAP@0.5:0.95 around 85%, with an average confidence score of 88.30% during real-time testing using a webcam. These findings demonstrate that YOLOv5s can accurately and efficiently classify waste objects, offering strong potential for integration into digital waste bank systems to enhance the efficiency and transparency of waste management processes.
