Abstract

Lighting efficiency is vital for energy management and sustainability aboard maritime vessels. This study aims to examine the comparative energy efficiency, luminous efficacy, and performance stability of light-emitting diode (LED) and fluorescent (FL) lighting systems onboard the Sultan Hasanuddin maritime training ship operated by Politeknik Ilmu Pelayaran Makassar, Indonesia. Using a quantitative experimental approach, the research combined lamp testing, shipboard lighting audits, and simulation-based analysis under actual operational conditions from June to December 2024. The results demonstrated that LED lamps achieved an average luminous efficacy of 202.4 lm/W, significantly higher than the 39.1 lm/W recorded for FL lamps. The transition to LED reduced accommodation lighting power consumption from 4,860 to 1,482 watts, with a 29.7% increase in total luminous output, while projected energy consumption fell by approximately 80.7% over the study period—indicating substantial potential for operational cost savings and emissions reductions. LED lamps also showed superior performance stability under controlled testing, maintaining consistent illumination without noticeable degradation, whereas FL lamps experienced gradual brightness decline and frequent maintenance issues. These findings suggest that adopting LED lighting on maritime training ships offers significant benefits in energy efficiency, operational reliability, and sustainability. However, because LED performance is partly based on simulation, further long-term onboard validation is recommended. The study offers practical recommendations for maritime institutions seeking to modernize shipboard lighting and contributes to broader energy efficiency goals in the maritime sector.
