Abstract

Fiscal decentralization has become a central policy instrument in Indonesia’s regional development strategy since the early 2000s. However, empirical findings on its impact on regional economic growth remain inconclusive. This study examines the effect of fiscal decentralization on economic growth across Indonesian districts by synthesizing evidence from panel data–based empirical studies and contextualizing them within decentralization theory. The study adopts a qualitative systematic review and comparative empirical synthesis approach, focusing on indicators such as regional own-source revenue, intergovernmental transfers, and government expenditure. The findings indicate that fiscal decentralization generally exerts a positive influence on regional economic growth, particularly through increased local revenue capacity and productive government spending. However, the impact varies across regions due to differences in fiscal capacity, governance quality, and dependency on central government transfers. Several studies also reveal that excessive reliance on general allocation funds may weaken growth incentives. This study contributes to the literature by integrating diverse empirical results into a coherent analytical framework and highlighting policy conditions under which fiscal decentralization promotes sustainable regional growth. The findings support the need for strengthening local fiscal autonomy while improving accountability and expenditure efficiency at the district level.

Abstract

Asphalt Concrete–Wearing Course (AC-WC) is a critical pavement layer directly exposed to traffic loads and environmental conditions. In tropical cities such as Palangka Raya, variations in asphalt mixture composition significantly influence pavement durability, particularly Marshall stability. This study aims to comprehensively evaluate the effect of AC-WC asphalt mixture variations on Marshall stability in Palangka Raya City through a systematic synthesis of experimental studies published between 2012 and 2025. The research method employed a qualitative–quantitative comparative analysis of 30 peer-reviewed journal articles, theses, and dissertations focusing on AC-WC mixtures incorporating modifiers such as Asbuton, polymer additives, fillers, temperature variations, and immersion conditions. The results indicate that asphalt modifiers—especially polyethylene-based polymers, Asbuton granular asphalt, and alternative fillers—consistently enhance Marshall stability, with optimal stability generally achieved within 2–5% additive content. Environmental factors, including water immersion and temperature variations, were found to significantly reduce stability if not properly controlled. Overall, most AC-WC mixtures evaluated met the Indonesian Bina Marga 2018 specifications, demonstrating their suitability for heavy traffic conditions. This study contributes to pavement engineering by providing a consolidated technical reference for optimizing AC-WC mixture design in tropical urban environments.
