Engagement and support for air quality improvement through MRT usage among freshman students in Jakarta

Abstract

Abstract Jakarta faces an air quality crisis exacerbated by vehicle emissions and urban congestion, with policymakers seeking effective solutions. This study explores attitudes and behaviours regarding Mass Rapid Transit (MRT) usage among freshmen at Universitas Pertamina. Using Exploratory Factor Analysis (EFA) and cluster analysis on data from 189 valid samples, the research identifies three distinct factors: Environmental and Governmental Support for MRT, Personal and Productivity Benefits of MRT, and Accessibility and Operational Convenience of MRT. The cluster analysis reveals three student groups: Fully Engaged, Environmentally Benefit Seekers, and Less Engaged. Findings indicate that regular MRT users are more supportive of air quality initiatives, suggesting targeted educational campaigns and improved MRT accessibility could promote sustainable transport habits. Policy measures such as fare subsidies and better public transport integration may further encourage MRT adoption, contributing to Jakarta’s clean air goals.
