Abstract

This study aims to identify and analyze the partial and simultaneous effects of Gross Regional Domestic Product (GRDP) per capita, the poverty rate, and the unemployment rate on community welfare, as measured by the Human Development Index (HDI), in Medan City. It also examines these determinants from the perspective of Islamic Economics. The study employed a quantitative approach with a causal associative research design. The data used were secondary time-series data covering the period from 2005 to 2025, obtained from Statistics Indonesia (Badan Pusat Statistik/BPS). The sampling technique applied was purposive sampling. To ensure an adequate sample size for macroeconomic statistical analysis, the annual data were transformed (disaggregated) into quarterly data, resulting in a total of 84 observational samples. The data were analyzed using multiple linear regression with SPSS version 26. The partial test (t-test) revealed that GRDP per capita has a positive and significant effect on community welfare (HDI). In contrast, the poverty rate and the unemployment rate were found to have negative and significant effects on the HDI of Medan City. Simultaneously (F-test), the three independent variables have a significant effect on the dependent variable, with a coefficient of determination (R²) of 80%, indicating that 80% of the variation in community welfare (HDI) is explained by the model, while the remaining 20% is influenced by other factors outside the scope of this study.

Abstract

Background: Aceh Province has abundant marine resources with a coastline exceeding 2,500 kilometers, yet the fisheries sector's contribution to Gross Regional Domestic Product remains low at only 5.23%. Excessive exploitation, marine pollution, and mangrove degradation threaten ecological sustainability and coastal community welfare. The blue economy concept offers a sustainable development approach balancing economic growth and environmental preservation. Research Gap: Previous studies have generally focused on specific sectors such as coral reef conservation without integrating multidisciplinary analysis encompassing ecological, socio-cultural, and institutional policy aspects comprehensively. Limited research has examined blue economy implementation in Aceh with a focus on local wisdom integration. Novelty: This study offers an integrative approach combining economic, ecological, and institutional governance dimensions within a single analytical framework. It specifically examines the role of Panglima Laot traditional institutions in marine governance, an aspect underexplored in previous literature, and proposes an adaptive policy model integrating ecologically based incentives. Method: A qualitative descriptive analytical approach was employed. Data were collected through in-depth interviews, field observations, and documentation with informants including traditional leaders (Panglima Laot) and representatives of the Maritime Affairs and Fisheries Agency. Data analysis followed the Miles and Huberman interactive model through data reduction, presentation, and conclusion drawing. Results: Implementation of the blue economy in Aceh includes marine ecosystem conservation, mangrove rehabilitation (100 hectares annually), fish house construction, and establishment of 149,000 hectares of Marine Protected Areas. Challenges include limited human resources, inadequate infrastructure, budget constraints, and overlapping authority between central and regional governments. Panglima Laot traditional institutions play a strategic role in regulating fishing zones, enforcing customary bans, and strengthening participatory marine governance. Conclusion: Integration of blue economy policies with local wisdom is essential for realizing sustainable and equitable marine resource management. Strengthening customary institutions, improving inter-agency coordination, and enhancing fisher capacity are critical for optimizing marine potential and improving coastal community welfare.
