Abstract

The Merak and Bakauheni Crossing Ports are a port connection for the Merak-Bakauheni crossing which is referred to as the main bridge in connecting the islands of Java and Sumatra. Each port has various facilities that can support port operational activities, one of which is Local Port Services (LPS). Local Port Services (LPS) is a service for ship traffic that is only limited to providing information about port and terminal needs and operational data that is not responsive to shipping traffic within the coverage area of the relevant station. The feasibility of these facilities is very important for the purpose of communication with ships that will enter and exit the pier as well as supervision of the arrival and departure process of ships. The method used is an observation method so that data is obtained by making observations directly at the research location. At the Merak and Bakauheni crossing ports, there are already Local Port Services (LPS) facilities but based on the results of observations in the field, there are discrepancies with applicable regulations such as the condition of room needs and the competence of human resources needed for Local Port Services (LPS) activities. This study uses the Gap Analysis method to determine the gap between existing conditions and the Regulation of the Director General of Land Transportation Number: PR-DRJD 4 of 2021. Based on the results of the research by looking at the situation firsthand, it was found that there was a discrepancy with the Regulation of the Director General of Land Transportation Number: PR-DRJD 4 of 2021, namely trees and gangways that obstruct the indicators of free view to the water coverage area and the required human resource competencies have not been fulfilled. Efforts are made so that Local Port Services (LPS) activities can run optimally by felling trees and planning the relocation of Local Port Services (LPS) activities and involving existing human resources in various education and training activities in accordance with the required competencies.

Abstract

River and lake traffic signs play an important role in maintaining the safety of water navigation, but there is still a lack of understanding and supporting technology to recognize them automatically. This study aims to compare the performance of two popular object detection methods, namely YOLOv7 and Single Shot Multibox Detector (SSD), in identifying river and lake signs based on digital images. The dataset used consists of 6,650 images, including original data and data that has been augmented with visual degradation such as low resolution, noise, blur, lighting artifacts, occlusion, and cluttered background. This study evaluates the models based on accuracy, precision, and recall metrics. The test results show that YOLOv7 excels in all metrics, with the highest accuracy of 78%, compared to SSD which only reaches 70%. Both models experience a significant decrease in performance under occlusion and cluttered background conditions, but YOLOv7 still shows better resilience. Meanwhile, the blur condition is the degradation that least affects the performance of both models. These findings confirm that YOLOv7 is more robust to visual disturbances and can be a more effective alternative in automatic river and lake traffic sign recognition systems.
