Ballast water plays a crucial role in maintaining ship stability during shipping, but it also carries environmental and human health risks due to the heavy metals it carries. This study aims to examine the health risks posed by exposure to heavy metals in ballast water and to assess the effectiveness of management practices implemented in the maritime industry. Using a literature review method, this study examines various scientific sources related to the content of heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) in ballast water, as well as their impacts on human health and marine ecosystems. The results indicate that heavy metals in ballast water can cause long-term toxic effects such as neurological disorders, kidney damage, and respiratory and reproductive disorders. The greatest risk is experienced by maritime workers who are directly exposed through inhalation or skin contact during the ballast water sampling and processing process. To minimize these risks, strict work safety protocols, improved ballast water treatment technology, and regular monitoring of heavy metal levels are required. Thus, this study emphasizes the importance of strengthening ballast water management policies and practices that are oriented towards human health and environmental sustainability.  

Marine conservation areas play a crucial role in maintaining the sustainability of aquatic ecosystems and fishery resources. However, many fishing vessels still violate regulations by entering and exploiting conservation areas without permission. This study aims to analyze the compliance level of fishing vessels with conservation regulations in the Anambas Islands, identify the factors contributing to non-compliance, and evaluate the effectiveness of the imposed sanctions. The research employs a qualitative and quantitative descriptive approach, utilizing SWOT analysis to assess internal and external factors affecting compliance. Data were collected through vessel movement monitoring using the Vessel Monitoring System (VMS), interviews with fishery inspectors, and analysis of relevant policy documents. The findings indicate that many fishing vessels fail to comply with conservation regulations, mainly due to fish migration into conservation areas, deliberate violations by business operators seeking higher profits, and a lack of understanding among captains regarding conservation boundaries. Additionally, limited human resources and monitoring facilities hinder effective law enforcement. Although sanctions are regulated under Government Regulation No. 85 of 2021, their effectiveness remains low, as evidenced by recurring violations. Therefore, strengthening supervision, optimizing monitoring technology, and raising fishermen’s awareness of conservation regulations are necessary to enhance compliance among fishing vessels and preserve marine ecosystems.

The sea fence in Tangerang Regency, Banten, has become a complex issue involving violations of spatial law, environmental impacts, and the rights of coastal communities. This research analyzes the social and environmental impacts of the case and examines the protection and restoration of victims' rights based on a greenvictimology perspective. Using an empirical juridical approach, data collection was conducted through interviews with fishermen and legal aid organizations, as well as secondary data from legal literature. The results showed that sea fences disrupt fishermen's activities, damage marine ecosystems, and violate regional spatial regulations. Ecological impacts include changes in ocean currents, decreased water quality, disruption of fish migration, damage to coral reefs, and coastal abrasion. Protection and restoration of victims' rights in the Pagar Laut case to date have not been fully fulfilled and realized by the responsible parties. This can be seen from the absence of concrete policies and concrete actions in the form of providing compensation or compensation to fishermen who are directly affected by the installation of the Sea Fence which hampers their access and space for fishing activities. In addition, efforts to restore the marine environment have also not been carried out optimally, especially in terms of dismantling sea fences that have not been carried out thoroughly and assistance programs from the Ministry of Maritime Affairs and Fisheries have not been implemented.

Coastal areas are transitional areas between land and marine ecosystems that are very vulnerable to natural disasters, one of which is abrasion. Coastal abrasion is the process of erosion of coastal areas caused by wave activity, ocean currents, and human activities such as infrastructure development and sand mining. Ciberi Beach (Tanjung Ciberi) located in Enggros Village, Abepura District, Jayapura City, is one of the coastal areas that experiences continuous abrasion. Its strategic location and direct facing the Pacific Ocean makes this area very vulnerable to coastal erosion. Based on the author's experience while conducting Field Work Practices at the Papua River Basin Center (BWS Papua), it is known that abrasion has caused damage to public facilities and significant coastline decline since 2019 (Cepos, 2024). Strong suspicions arose from the community based on the results of interviews conducted that the construction of the Youtefa Bridge contributed to the acceleration of abrasion. Previous research also showed that the rate of abrasion in the Yos Sudarso Bay area, including Ciberi Beach, reached 0.89 meters per year. Therefore, this study aims to analyze the level of damage to Ciberi Beach due to abrasion during the period 2014–2024, and to provide recommendations for handling to reduce the impact of damage in the coastal area.

Turtles are integral components of two ecosystems, both coastal and marine. They play a crucial role in maintaining a healthy marine ecosystem. A nutritious sea fosters millions of fish, serving as a significant protein source for humans. However, this is increasingly at odds with the presence of turtles, which are gradually becoming endangered. This issue stems from various factors, including large-scale commercial fishing activities near turtle nesting sites and worsening climatic changes. These factors have the potential to disrupt the balance of marine ecosystems. The approach adopted in this design is an ecological architecture approach. It aims to restore turtle habitats in coastal conservation areas to attract nesting turtles and sustainably develop tourist facilities that harmonize with the surrounding environment.

The pace of global environmental change and the intensification of human activities have put significant pressure on marine ecosystems, threatening the sustainability of many species that are important both for ecosystems and the economies of coastal communities. In this context, this study aims to evaluate the application of genetic technologies in the conservation of endangered marine species, focusing on environmental DNA (eDNA) monitoring, CRISPR genetic engineering techniques and population genetic analysis. The method used was a literature review that examined current academic sources related to genetic technologies and their implementation in conservation. Findings show that eDNA is a highly effective tool in species and habitat monitoring, and has been successful in specific cases such as Napoleon fish and green turtles in Raja Ampat. In contrast, CRISPR techniques offer the potential to improve the genetic resilience of species, despite significant regulatory and ethical challenges. The implications of this study emphasize the need for strong policy support and international collaboration to address these challenges and optimize the use of genetic technologies in more effective conservation strategies in the future.      

The Natuna Sea is one of Indonesia's territorial waters that borders many countries so that it is often an easy target for illegal fishing, including ships belonging to China, Vietnam and Thailand.  Not only does it harm the country's economy and local fishermen, but illegal fishing also causes damage to marine ecosystems and coral reefs, even though Indonesia as a country that ratified the United Nations Convention on the Law of the Sea or commonly referred to as UNCLOS has adopted rules governing this in its law. Using the Base on research method that we collected from various journals, websites, electronic scientific articles and other research reports, we attempt to (1) analyse the effectiveness of UNCLOS in addressing maritime issues such as illegal fishing (2) to determine the compliance of UNCLOS ratifying countries involved in illegal fishing cases in the Natuna Sea seen from green politics theory and Robert B. Mitchell's compliance theory. Mitchell's compliance theory.  The results we found are that the entry of ships belonging to China, Vietnam and Thailand into the Natuna Sea shows the ineffectiveness of UNCLOS and the lack of compliance of the ratifying countries.
