FACTOR ANALYSIS AND COST CALCULATION OF SOLAR ENERGY IMPLEMENTATION IN AVIATION MAINTENANCE, REPAIR & OVERHAUL (MRO)

Background: The global imperative to address climate change has heightened awareness of sustainable practices across industries. Emissions from the aviation industry contribute significantly to global warming, with Maintenance, Repair, and Overhaul (MRO) activities contributing to aviation emissions. Hence, efforts are needed to reduce emissions by transitioning from fossil energy to renewable energy.   Methods: Used pairwise comparisons among seven factors was conducted by collecting data using structured interview from 15 expert respondents, comprising staff, managers, senior managers, and directors from five major Aviation MRO facilities in Indonesia equipped with hangar facilities. The respondents were selected based on their expertise and experience in the Aviation MRO industry. Following the structured interview, life cycle cost calculations were performed to compare the use of electricity from the national grid (PLN), leased Solar PV, and purchased Solar PV.   Results: Findings revealed positive acceptance across Technical Awareness, Economy, Environment, and Policy aspects in the first structured interview section. Then provided insights into respondents' priorities, with Cost, Lifecycle, Environmental Impact, Government Support, Capacity, Quality, and Payment Scheme ranked in order of importance in selecting electricity energy sources. Additionally, life cycle cost calculations demonstrate significant cost efficiency in both investment and leasing schemes for solar photovoltaic installation, highlighting the industry's potential contribution to emissions reduction.   Conclusions: Integrating renewable solar energy into hangar operations presents an opportunity for the MRO industry to enhance business efficiency while advancing environmental sustainability. Government support and incentivization are essential to encourage broader adoption of renewable energy initiatives within the Aviation MRO sector.
