Radar is one of the most important navigational aids on board ships, as it detects targets, coastlines, and weather in conditions in which visual observation is limited and supports collision avoidance in accordance with the COLREGs. Its reliability depends not only on correct operation by the officers of the watch but also on the condition of its components, particularly the magnetron, which has a limited service life. This study analyses the use of radar on board the MV Sinar Kintamani, identifies the factors that made its performance less than optimal, and proposes measures to improve the safety of navigation. A qualitative descriptive design was used, with data collected through observation of radar operation on the bridge, interviews with the Master, Chief Officer, and Second Officer, and review of the radar documentation and service report during the authors’ sea practice, supported by a literature review. The ship is fitted with a JRC JMA-9933-SA S-band radar and a JMA-9923 X-band radar. On 15 November 2023, while the ship was passing through the Selayar Strait, the radar displayed false echoes and failed to show some targets clearly. The service report showed that the magnetrons had accumulated 5,908 and 5,701 transmitting hours, well beyond the optimal service life of about 4,000 hours stated by the manufacturer, and they were replaced on 4 June 2024, after which both radars functioned normally. Other contributing factors were inappropriate display and range settings, irregular performance checks, planned maintenance that was recorded but not carried out, unstable electrical supply, and faulty cable connections. Monitoring of magnetron transmitting hours, planned maintenance in accordance with the manufacturer’s manual, regular performance checks, and training of officers in radar operation and interpretation are recommended.
