Abstract

Ships are sea transportation that is often used in Indonesia. However, who would have thought that the transportation would become a case because of the frequent occurrence of accidents. This has been proven from data from the KNKT (National Transportation Safety Committee) which noted that from 2012 to 2017 there had been an increase in accidents in the waters. In fact, according to the National Search and Rescue Agency (Basarnas) in 2020 there have been 878 incidents with victims reaching 4658 people. In this final project, the author makes a prototype of BNWAS (Bridge Navigational Watch Alarm System) equipped with obstacle warning using image processing with the otsu method strengthened by thresholding-based segmentation with inverse technique (TsTN), distance detection using the triangle similarity method, real-time tracking with GPS (Global Positioning System) and the entire system can be observed on the Android application. The Final Project performs several analyzes including performance analysis by calculating the accuracy of the BNWAS alarm system, image detection accuracy, distance detection accuracy, GPS accuracy, overall system testing accuracy and packet loss. The accuracy of each system is very good because the error is below 2%, while for overall system testing has a very good performance with a delay of 179.8 ms and 0% packet loss.

Abstract

This study discusses the preventive measures against piracy attacks faced by MV. X while transiting High Risk Areas. The purpose of this research is to identify the vessel’s vulnerability factors to piracy attacks and analyze the procedures and preventive actions that have been implemented. A descriptive qualitative method was used, including observation, in-depth interviews with crew members and armed guards, as well as document analysis of anti-piracy SOPs. The research findings show that the vulnerabilities of MV. X are due to limited drill training, suboptimal implementation of procedures, and inconsistency in the use of personal protective equipment (PPE). Based on these findings, it is recommended to increase the frequency and depth of simulation drills, enforce PPE usage standards, and update deck access security procedures. In conclusion, consistent implementation of procedures and structured training will enhance vessel security during High Risk Area transits.

Abstract

The loading and unloading process is one of the most vital activities in port operations and plays a significant role in ensuring the smooth flow of national logistics. However, in practice, various forms of inefficiency are still frequently encountered, such as high ship waiting times, low utilization of loading and unloading equipment, and imbalances in labor scheduling and cargo flow in the yard area. These conditions increase turnaround times and hinder port productivity. To address these issues, an analytical approach is needed that can comprehensively model system behavior so that the causes of inefficiency can be precisely identified and tested through improvement scenarios without disrupting actual operations. This study aims to analyze the efficiency level of the ship loading and unloading process at the Port of Tanjung Emas Semarang by applying the Discrete Event Simulation (DES) method using Arena software. The model was developed to describe the flow of activities from ship arrival, through the service process using cranes, to the distribution of cargo to the storage area. Model validation was carried out by comparing simulation results with actual data. The results showed that the combination scenario of adding cranes and adjusting shift schedules provided the most significant efficiency improvement, with a reduction in ship dwell time of up to 20%, waiting time of up to 30%, and an increase in crane utilization of up to 83%. These findings confirm that DES is effective as an analytical tool and basis for operational decision-making at ports.
