Abstract

Breakwater construction in Indonesia frequently employs tetrapods to dissipate wave energy. However, the placement process remains manual, relying on divers to guide crane operators. This approach not only poses safety risks but also limits visibility due to underwater turbidity. While prior research has focused on underwater image enhancement, the integration of tetrapod object detection remains unexplored. This study proposes a combined method of underwater image enhancement and tetrapod object detection to support land-based operator visualization. Auto-level filtering and histogram equalization techniques were applied to enhance image clarity, followed by object detection using the YOLOv7-tiny model. Tetrapod models at a 1:20 scale were used for training and testing. The proposed system achieved a mean average precision (mAP) of 0.95. Evaluation was conducted across 12 scenarios, involving four lighting levels and two water conditions: clear and 45.8% turbidity. The object detection confidence scores were 0.80 without enhancement, 0.85 with histogram equalization, and 0.84 with auto-level filtering. Multiple object detection achieved an accuracy of 88.75%, outperforming previous approaches using YOLOv4-tiny. The results demonstrate the potential of integrating image enhancement and deep learning-based object detection for improving underwater operational safety and placement precision in breakwater construction.

Abstract

The palm oil industry is one of the strategic sectors that contributes significantly to the Indonesian economy. However, this industry still faces various challenges, particularly in terms of operational efficiency and the implementation of digitalization, especially at the level of independent farmers who often still use manual methods to determine the ripeness of the fruit. This manual process is prone to subjectivity, which can impact harvest quality and supply chain efficiency. To address this issue, this study proposes a palm oil fruit ripeness detection system based on the YOLOv11 algorithm, chosen for its advantages in inference speed and detection accuracy, especially when run on devices with limited resources. The developed model was then implemented using the ONNX Runtime Framework. This enables accelerated inference processes and supports portability on hardware with limited resources. Test results show that the model achieves an mAP@50 accuracy of 90.2% with an average latency of around 255 ms to 300 ms. With these achievements, this system is not only reliable in detecting fruit ripeness, but also efficient in processing time and relevant to support digital transformation in the palm oil plantation sector.

Abstract

Kelapa Sawit merupakan komoditas strategis di Indonesia yang menjadi salah satusumber devisa utama. Tingkat kematangan buah kelapa sawit sangat berpengaruhterhadap kualitas minyak yang dihasilkan, sehingga diperlukan metode yang cepat,tepat, dan konsisten untuk mendeteksi tingkat kematangan buah. Dalam metedoKonversional masih mengandalkan pengamatan visual oleh pekerja lapangan seringbersifat subjektif dan tidak efesien.Dengan hal tersebut,penelitian ini mengusulkanpenerapan model object detection berbasis YOLOv11 untuk mendeteksikematangan buah kelapa sawit. Model YOLOv11 dipilih karena memilikikeunggulan dalam kecepatan inferensi dan akurasi deteksi pada objek kecil maupunkompleks. Untuk memfasilitasi penggunaan di lingkungan produksi,Model yangtelah dilatih dikonversi ke format ONNX dan dijalankan menggunakan ONNXRuntime agar memperoleh perfoma inferensi yang lebih optimal pada sumber dayaterbatas. Selanjutnya, aplikasi antarmuka berbasis Streamlit dikembangkan untukmemudahkan pengguna dalam mengunggah gambar atau video dan memperolehhasil deteksi secara real-time. Diharapkan, sistem ini mampu memberikan solusipraktis, efisien, dan akurat dalam mendukung proses panen buah kelapa sawit.
