“…QR code is a two-dimensional code that can store and convey information quickly [4]. The principle of a QR code is the same as a barcode [7], The QR code is displayed in two dimensions (vertical and horizontal), while the barcode is shown in one dimension [4], [10], QR codes can store information as much as 4,296 alphanumeric characters, 7,089 numeric characters, and 1,817 kanji characters [11], In addition, the speed of delivering QR code information is faster than barcodes [5]. The advantages of QR codes are multifunction, large data storage capacity, less paper usage, resistance to dirt and damage, readable from various directions at an angle of 360°, and the structure can be elongated [11], However, QR codes have a weakness, namely the lack of understanding about QR codes.…”

System and outfitting in a ship vary with different brands and treatment methods. These conditions can be an issue if the operator has undisclosed damages due to a lack of knowledge about the ship's maintenance records. An electronic planned maintenance system (ePMS) is a system that is currently used to collect the ship maintenance recorded data. However, the use of ePMS still has drawbacks. The appearance is less interactive, available information about the outfitting used in ships is limited, and the operator needs to search the outfitting manually with scrolling. This research aims to study the application of QR code technology for monitoring maintenance activities of ship systems and outfitting. This research was conducted based on field observation of ePMS, designing a QR code module for the ePMS application, developing algorithms, and creating programs for website and android based applications. In addition, trials of the application and calculation of the costs incurred for implementing the QR code method are also carried out. The distribution of questionnaires for practitioners accompanied the trial. Based on that, the implementation of QR code in ePMS can be applied, easy to use and facilitate the supervision of ship system and outfitting activities with a mean score of 4.39 or equivalent to strongly agree. The addition of the QR code module is costed IDR120,426,000.00, where the process of recognizing and searching for ship systems and outfitting to view maintenance plans and maintenance history on the ePMS application is enough by scanning a QR code.

Conventional welding techniques for complex structures often rely on human involvement, which can be prone to errors when deviations from the planned process occur. In contrast, robotic welding is highly precise and effective, particularly in the assembly of complex structures such as double-bottom ships. Therefore, this paper presents a comprehensive technical and economic analysis comparing robotic welding to conventional welding in the assembly process of a ship’s block panels. The study aims to evaluate and compare the strategies employed in robotic welding and conventional welding, with a specific focus on the ship double-bottom context. Furthermore, an economic value analysis is conducted to assess the cost effectiveness of each approach. The analysis reveals that robotic welding can achieve a significantly faster welding speed, completing the process approximately 3.85 times quicker compared to conventional methods. Moreover, the ratio of electricity and man-hours between robot welding and conventional welding is 1:2.75. These findings highlight the potential for cost savings by implementing robotic welding processes. The analysis reveals a significant difference in operational costs, highlighting the efficiency and cost effectiveness of robotic welding compared to conventional methods.

The shipbuilding sector is currently facing issues due to long manufacturing schedules and delays in ship construction completion. These challenges come from national shipyards' conventional onboard outfitting process for equipment installation, which takes a lengthy time to complete. To address this issue, this study proposes implementing the advanced outfitting system (AOS) approach, which combines the zone outfitting system with the hull block construction method, in building a 2000 GT ship at PT. X in Surabaya, Indonesia. Technical analysis is performed to plan the shipbuilding process using the hull block construction method, and the efficiency of man-hours is calculated by implementing the AOS approach. The study also conducts an analysis of shipbuilding costs and the required shipyard development investment. The technical analysis shows that the AOS approach improves efficiency factors by enhancing material handling and testing activities. The AOS method has an efficiency factor of 50% for on-unit outfitting and 62% for on-block outfitting, compared to on-board outfitting. The construction of a 2000 GT ship employing the AOS approach represents a reduction of approximately 9.6% in working days and a cost-saving of approximately 4.3% when compared to the onboard outfitting method, resulting in savings of IDR 1,933,277,000 or about USD 124,175. To implement the AOS approach, an investment of IDR 3,040,776,000 or about USD 195,310 is required for construction facilities and human resources development. The return on investment is obtained after two 2000 GT ships are completed. As a result, the AOS approach can improve shipbuilding productivity by reducing construction time and costs. This study provides insights into the benefits of implementing modern shipbuilding techniques in the industry.
