Pengembangan teknologi blockchain melalui digital decklogbook (N-cord) pada kapal yang berlabuh jangkar (at anchor)

Abstract

This research was motivated by the need for a ship activity recording system during anchorage operations that is more secure, efficient, and capable of maintaining data integrity. The purpose of this study is to develop a blockchain-based Digital Deck Logbook application called N-CORD as a monitoring and documentation tool for ships at anchor. This research applied a Research and Development (R&D) approach with data collection methods including observation, interviews, literature study, and system testing. Blockchain technology was implemented to support data security through the concept of immutability, ensuring that stored data cannot be easily altered. The system was also designed with multi-user authentication to provide different access levels according to each user’s duties and responsibilities. The results showed that the N-CORD application assists watchkeeping officers in monitoring and recording ship activities in a more structured, faster, and accessible manner. In addition, blockchain integration enhances data integrity protection and increases reliability in ship operational documentation processes. Based on the testing results, the system was considered capable of fulfilling user needs in terms of functionality and ease of use. Therefore, the N-CORD application can serve as a digital solution that supports the development of blockchain technology in maritime operations, particularly for ship monitoring processes while at anchor.
