Abstract

This study examines the effects of road infrastructure, sea-transport frequency, and electricity consumption on the poverty rate in Tual City during 2015–2025. Tual is an archipelagic city whose economic opportunities and access to basic services are strongly shaped by land connectivity, maritime mobility, and reliable energy. The study uses annual secondary data from Statistics Indonesia and the Tual City government. A quantitative explanatory design and multiple linear regression are employed, accompanied by normality, multicollinearity, heteroskedasticity, and autocorrelation tests. The findings show that road infrastructure has a negative and statistically significant effect on poverty (coefficient = -0.456698; p = 0.0405). Electricity consumption also has a negative and significant effect (coefficient = -0.222964; p = 0.0297). In contrast, sea-transport frequency has a positive but statistically insignificant coefficient (0.038299; p = 0.1436), indicating that the number of ship calls alone has not yet translated into poverty reduction. Jointly, the three variables significantly explain changes in poverty, with R-squared of 0.725129. The results imply that poverty reduction in an archipelagic region requires integrated policies: maintaining strategic roads, expanding productive and affordable electricity use, and improving the quality, capacity, scheduling, and intermodal integration of maritime logistics.
