Strategi Energy Efficiency Operational Index (EEOI) sebagai Instrumen Pengendalian Emisi Gas Buang Mesin Diesel di Kapal Modern

Abstract

The transition toward sustainable maritime operations requires a standardized and measurable indicator to evaluate ship energy performance in real operating conditions. The Energy Efficiency Operational Index (EEOI), recommended by the International Maritime Organization (IMO), provides a quantitative measure of CO₂ emissions relative to fuel consumption. This paper examines strategic approaches for implementing EEOI as a practical emissions control instrument for modern ships, focusing on calculation methods, operational parameters, and supporting technologies that influence index performance. The analysis highlights that consistent application of EEOI enables ship operators to identify energy-inefficient operating patterns and supports decision making for fuel saving measures such as optimized voyage planning, and propulsion system tuning. Furthermore, the integration of digital monitoring and realtime data analytics significantly enhances the accuracy and responsiveness of EEOI assessments. The findings indicate that EEOI functions not only as a compliance reporting tool but also as a core component of energy management strategies aimed at meeting IMO 2030–2050 emission reduction targets. Effective utilization of the index contributes to more efficient, economical, and environmentally responsible ship operations
