Formation of Strategic Provinces on Maritime Borders: A Political Economy Analysis of Natuna-Anambas Proposal
Get PDFThe Natuna and Anambas regions have a strategic position as a maritime border region that is a concern in the national agenda, including through designation as part of the National Strategic Project (PSN). However, the reality of local development shows high fiscal dependence on central transfers, weak local revenue, and vulnerability to global economic fluctuations. This study aims to assess the potential of the Natuna-Anambas Province formation in strengthening fiscal independence and improving local economic governance. Using an exploratory qualitative approach and fiscal policy analysis, this study utilizes secondary data from regional financial reports, BPS statistics, and a literature review related to fiscal decentralization and the resource curse. The results show that the regional revenue structure dominated by the General Allocation Fund (DAU) and Revenue Sharing Fund (DBH) makes Natuna and Anambas vulnerable to central policy changes and commodity price volatility. In addition, the benefits of PSN have not been fully distributed to local communities due to limited institutional capacity and lack of integration of local economic development. The establishment of a new province has the potential to be a solution if accompanied by strengthening fiscal governance, reforming DBH allocation, and economic diversification strategies. This article recommends a policy roadmap based on a multi-level governance approach to promote fiscal autonomy and inclusive and sustainable economic development
Maritime Security and Drug Threats in the Border Waters of Bintan Regency: The Perspective of the Bintan Resort Police
Get PDFBintan Regency, located in Indonesia’s Riau Islands Province, occupies a strategic maritime position adjacent to Singapore and Malaysia, making it a vital yet vulnerable zone for transnational narcotics trafficking. The geographical characteristics of extensive coastlines, scattered small islands, and numerous unofficial ports provide opportunities for smugglers to exploit weak surveillance and limited enforcement capacity. This study aims to analyze the strategies, challenges, and institutional coordination of the Bintan Resort Police (Polres Bintan) in combating maritime-based narcotics smuggling. Using a qualitative descriptive method, data were collected through in-depth interviews, direct observation, and documentation studies, then analyzed using the Miles and Huberman model with triangulation for validation. The findings reveal that the Polres Bintan plays a crucial role in early detection and prevention through routine patrols, intelligence sharing, and coordination with the Navy, Customs, and BNN. However, enforcement remains constrained by limited personnel, only two patrol vessels, and the absence of an integrated maritime surveillance system. Inter-agency coordination is still fragmented due to overlapping authority and the lack of formal legal frameworks. Moreover, socio-economic vulnerabilities within coastal communities increase local involvement in smuggling networks. The study concludes that sustainable maritime security requires strengthening institutional synergy, enhancing technological capacity, and empowering communities as active partners in surveillance. A unified maritime governance framework is essential to transform Bintan from a vulnerable transit hub into a resilient maritime border zone for Indonesia’s narcotics control strategy
Public Management Model in Marine Pollution Control; A Case Study of Bintan Regency
Get PDFMarine pollution is one of the most pressing environmental challenges in coastal areas, particularly in areas with intensive shipping and tourism activities such as Bintan Regency, Indonesia. Recurrent oil spills, accumulation of marine debris and microplastics, and degradation of mangrove and coral reef ecosystems highlight the need for an integrated governance model capable of ensuring both ecological sustainability and the socio-economic resilience of coastal communities. This study aims to assess the performance of public management in controlling marine pollution in Bintan and propose a governance model that emphasizes strengthening institutional coordination, preventive measures, and accountability mechanisms. The method used is a case study with a qualitative-descriptive approach, based on secondary data obtained from government documents, environmental regulations, media reports, and international scientific articles. Data were analyzed using thematic content analysis techniques to identify key issues, institutional roles, and the effectiveness of policy instruments. The results show that although regulatory frameworks such as PP No. 19/1999, DIKPLHD Bintan, and MARPOL obligations are in place, implementation in the field remains fragmentary and reactive, reflected in the recurrence of black oil pollution and limited ship waste reception facilities. This study emphasizes the importance of a polycentric governance model that integrates Integrated Coastal Zone Management (ICZM), collaborative governance between state and non-state actors, and economic instruments such as indirect fee schemes for wastewater treatment facilities. In conclusion, strengthening monitoring capacity, participatory evaluation, and multi-level actor integration are key to reducing the rate of recurrent pollution while protecting Bintan\u27s coastal ecosystems and communities
