Abstract

Locomotive radios serve as a crucial telecommunications system in railway operations. However, in Divisi Regional III Palembang, frequent malfunctions occur without systematic damage documentation, resulting in the absence of an optimal maintenance strategy. This study applies the Failure Mode and Effect Analysis (FMEA) method to identify failure characteristics, analyze their impact on each component, and determine the appropriate maintenance strategy. The analysis results indicate that from 2019 to 2022 a total of 20 communication failures occurred with the highest failure frequency observed in the Locomotive Transceiver Unit (LTU), which failed 14 times. The Mean Time Between Failure (MTBF) calculations reveal that the LTU has an average failure interval of 1,253 hours, while the Console has 1,297 hours, and the antenna reaches 8,064 hours. Risk analysis using FMEA shows that the console has the lowest risk level with a value of 18, the antenna has a moderate risk level with a value of 27, and the LTU has the highest risk level with a value of 36. Based on the identified maintenance strategy, the proposed solution includes implementing preventive maintenance and corrective maintenance to mitigate potential failures. A reliability test conducted over 1,000 hours yielded a reliability probability of 18.3%.

Abstract

This study aims to implement the djikstra algorithm to overcome the problem of optimizing the shortest route determination in aplousing and maintenance activities of Shipping Navigation Assistance Facilities (SBNP) in the working area of the Tanjung Perak Type A Navigation District Office. The Navigation Pier has historically been a strategic facility to face the challenges of maintaining fuel efficiency, sailing times and reducing emissions in environmental pollution due to suboptimal routes. The djikstra algorithm is known to be effective in finding the shortest route on a weighted graph by representing strategic location points such as ports and marine navigation areas as nodes and the distance between nodes is calculated using the haversine formula based on geographic coordinates as weights. Before the implementation of travel route optimization, a total mileage of 1,210.30 km was obtained and after the optimization was applied using the djikstra algorithm, a total mileage of 1,110.44 km was obtained. This comparison shows a significant distance savings of 99.86 km or 8.25% travel efficiency. This optimization is able to contribute to time reduction, fuel savings and reduction of environmental pollution exhaust gas emissions so that it is able to optimize the operational effectiveness of ships as a whole. This study confirms the positive and relevant capabilities to be applied in shipping navigation route planning and support decision-making in the management of sea routes or logistics transportation in areas with a varied distribution of mileage points that require high efficiency and mobility. In the next research, it is hoped that it will be able to add external factors such as sea currents, waves, and wind according to the geographical characteristics of the territorial waters so that the results of route planning can be more accurate in the real operational area in the shipping work area.

Abstract

The aplousing and maintenance activities of Shipping Navigation Assistance Facilities (SBNP) in the work area of the Tanjung Perak Type A Navigation District provide high efficiency in fuel use and travel time while minimizing the impact of environmental pollution. However, the shipping route so far has not been optimal, resulting in longer mileage, requiring excess fuel consumption and increased exhaust emissions. This study aims to optimize shipping routes through the application of the Traveling Salesman Problem (TSP) algorithm. The two approaches used are Heuristic Nearest Neighbor and Brute Force with case studies on 11 port points and islands in the waters of East Java. The simulation results showed that the Brute Force approach produced the most optimal route with a total distance of ±1,095.94 km more efficient than the Nearest Neighbor ±1,110.33 km and the initial route without optimization of ±1,284.3 km. This reduction in mileage has a positive impact on fuel savings, shipping time and reducing exhaust emissions. This study proves that the application of the TSP algorithm is able to increase operational efficiency and has the potential to be the basis for the development of technology-based decision-making support systems in environmentally friendly shipping route management.
