The Impact of Infrastructure Development in the Langkat Hilir Region, Langkat Regency

Abstract

This study aims to evaluate the development, impact, equity, and supporting and inhibiting factors of utility infrastructure development in the Langkat Hilir region, Langkat Regency, over the past five years (2019–2024). The research focuses on basic utilities such as electricity, clean water, sanitation, internet access, and drainage systems. A qualitative approach was employed using a case study design, with data collected through semi-structured interviews, focus group discussions (FGDs), field observations, and document analysis. Data were analyzed thematically using a reflexive thematic analysis approach. The findings indicate a significant improvement in infrastructure coverage: electricity access increased from 78% to 96%, clean water connections from 42% to 65%, adequate sanitation from 55% to 72%, internet access from 48% to 80%, and functioning drainage systems from 30% to 55%. The development of utilities has generated positive impacts across social, economic, and environmental dimensions enhancing access to education, communication, and healthcare; stimulating business activities and income opportunities; and reducing the risk of disease and flooding. However, these benefits have not been evenly distributed due to geographic disparities, variations in household economic capacity, and differing levels of community participation. Supporting factors for successful development include strong government commitment, active community involvement, technological support, and private sector engagement. Conversely, constraints include limited maintenance budgets, geographical barriers, suboptimal inter-agency coordination, land conflicts, and community behaviors that do not yet align with sustainability efforts. Recommended strategies for optimization and sustainability include needs-based planning, multi-sectoral coordination, community empowerment, the application of appropriate technology, sustainable financing schemes, and regular monitoring and evaluation. This study is expected to serve as a policy reference to enhance the effectiveness, equity, and sustainability of utility infrastructure development in similar regions.
