Indonesia, as the world's largest archipelagic nation with significant marine territory, faces major challenges related to Illegal, Unreported, and Unregulated (IUU) fishing. This issue negatively impacts local fishers and the national economy. This study examines Indonesia's maritime policies, including measures to combat IUU fishing through decisive actions such as sinking foreign vessels caught fishing illegally and introducing new policies like quota-based fishing. While these policies aim to reduce marine resource exploitation and promote sustainability, challenges persist, especially regarding the welfare of small-scale fishers who remain trapped in poverty. The research employs library research methods to explore the impact of policies on Indonesian fishers and the fisheries sector while highlighting the importance of more effective policies to balance stakeholders' interests and achieve sustainable fisheries management. Combating IUU fishing requires more comprehensive measures, including stricter monitoring and enhanced awareness among stakeholders in the fisheries sector.    

Blue carbon ecosystems play a strategic role in mitigating climate change through their ability to absorb and store carbon significantly. However, uncontrolled exploitation of marine resources, such as overfishing, destructive fishing methods, and fishing gear waste, have threatened the sustainability of blue carbon ecosystem. Penangkapan Ikan Terukur (PIT) policies implemented by the Indonesian government aims to realize sustainable fisheries by regulating fishing quotas based on zoning. This reserach aims to identify the urgency of integrating blue carbon ecosystems into PIT policies in Indonesia to maintain the sustainability of marine resources and support climate change mitigation. Using qualitative descriptive methods based on literature studies, this research found that integrating blue carbon ecosystems into PIT policies can provide significant ecological benefits. Strict monitoring, restoration of blue carbon ecosystem habitats, and implementation of scientific data-based policies are needed to ensure the success of this policy. This integration is expected to be able to maintain marine ecosystems, support sustainable fisheries, and contribute to global climate change mitigation targets.

Indonesia has significant fisheries potential due to its vast waters. Its abundant fishery resources have strong export potential. However, export activities often face challenges that cause export volumes to fluctuate. This fluctuation is influenced by various factors. These factors can be minimized using statistical methods such as Principal Component Analysis (PCA) and Factor Analysis. This study includes data characterization for each variable and testing PCA and factor analysis assumptions, including multivariate normality testing, independence testing (Bartlett's test), sampling adequacy (KMO test), anti-image correlation testing, PCA testing, and factor analysis. The results indicate that the percentage contribution of fisheries to GDP, the number of coastal villages with disaster mitigation facilities, and the average daily per capita calorie consumption from fish are relatively less dispersed and not highly variable around the mean. Additionally, all data meet the assumptions, and the sample size is adequate. Factors such as aquaculture pond production and the percentage contribution of fisheries to GDP sufficiently explain the data variations.
