Abstract

Bridge simulator learning is a core component of nautical cadet training because it allows learners to practise watchkeeping, collision avoidance, communication, and navigational decision-making in realistic but controlled scenarios. However, simulator sessions do not automatically produce reflective learning. Without a structured debriefing process, cadets may remember the technical sequence of the exercise but fail to analyse why decisions were effective, why errors occurred, and how lessons should be transferred to future bridge watch situations. This article aims to design a reflective debriefing model for bridge simulator learning in nautical cadet training. The study employed a design and development approach at the model-construction stage. The model was developed through literature synthesis covering experiential learning, reflective practice, simulation-based education, formative feedback, and maritime bridge resource management. The resulting model, named BRI-DAR (Benchmarking, Reaction, Inquiry, Decision Analysis, Action Reconstruction, and Reflective Transfer), consists of six debriefing phases supported by instructor prompts, cadet reflection sheets, scenario evidence, and a rubric for assessing reflective quality. The model integrates three learning orientations: technical reconstruction of navigational actions, non-technical analysis of communication and situational awareness, and transfer planning for future watchkeeping readiness. The article contributes a practical debriefing syntax, role distribution between instructor and cadets, an implementation flow for bridge simulator sessions, and assessment instruments that can be used in later empirical validation. The model is therefore presented as a design-stage framework, not as evidence of effectiveness; later studies still need to examine its effect on cadet performance, reflective competence, and situational awareness.

Abstract

Indonesia's pioneer ships burn subsidised fuel, yet their requests are often based on nominal daily figures from ship specifications rather than measured consumption. This study estimates the fuel demand and speed-related saving potential of KM. Bung Tomo, a 1,257 GT passenger ship serving pioneer route R-16 (836 nautical miles, 10-day round voyage) from Kalianget, Indonesia. Engine-room log-book data for one sailing day were combined with engine particulars and a propeller-law power–speed model calibrated to the logged main-engine consumption. The ship used 3,312 L per sailing day: 2,880 L in the main engines (120 L/h, about 31% of combined MCR) and 432 L in the generators (18 L/h, about 19% of one generator's rating). The calibrated model places the logged consumption at about 6.4 knots, at which one round voyage needs about 19,900 L (23.8 L per nautical mile; about IDR 135.5 million; 53.8 t CO₂ on a fossil-diesel basis). This matches the 20,000 L delivered per bunkering and the 21 kL requested for Voyage 16, whereas the specification figure applied over ten days would nearly double the estimate. Raising speed to 8 knots would add about 43% per voyage, while sailing at 6.0 knots would save about 2,000 L per voyage, or roughly 60,000 L and IDR 411 million over a 30-voyage contract, within the route's schedule margin. Low generator loading points to further savings. The fuel balance for the observation period could not be closed from available records, which makes record-keeping a precondition for efficiency management on small subsidised ships.
