Abstract

This study examines the impact of industrial activities in Bontang City, a major center for natural gas processing and fertilizer production, which potentially increases heavy metal contamination in coastal waters. Specifically, the research focuses on the accumulation of lead (Pb) and copper (Cu) in Anadara granosa, a benthic bivalve selected as a bioindicator due to its capacity to accumulate pollutants. The study aims to analyze Pb and Cu concentrations in Anadara granosa tissues collected from the waters of Selangan Hamlet, Bontang City, as an indicator of local environmental quality. The research was conducted over a six-month period, involving shellfish and water sampling from four observation stations. Heavy metal analysis was performed using Atomic Absorption Spectrophotometry, and the results were evaluated against relevant environmental quality standards, including Government Regulation of the Republic of Indonesia Number 22 of 2021. The findings revealed the presence of Pb and Cu at all sampling stations, with varying concentrations. The highest Pb and Cu levels were recorded at the South Station, while the lowest concentrations were observed at the East and North Stations. Overall, the measured concentrations of both metals significantly exceeded established safety limits, indicating serious risks to aquatic ecosystems and human health. These results confirm Anadara granosa as an effective bioindicator of heavy metal pollution and highlight the urgent need for further studies and mitigation efforts.

Abstract

This study examines the implementation of the Minister of Marine Affairs and Fisheries Regulation Number 7 of 2024 concerning the Management of Lobster, Crab, and Blue Swimming Crab in East Kalimantan. As a strategic policy, the regulation aims to ensure sustainable fisheries management through provisions on minimum catch sizes, restocking mechanisms, traceability systems, and law enforcement against illegal fishing and trade. Using an empirical juridical approach, this research collected primary data through questionnaires distributed to fisheries officers, coastal communities, fishers, and aquaculture business actors in East Kalimantan. The results show that the implementation of Regulation No. 7/2024 is generally categorized as moderately effective, with an average Likert score indicating limited but positive compliance. Respondents acknowledged the importance of sustainability principles embedded in the regulation; however, significant challenges persist, including insufficient formal socialization, weak field monitoring, lack of supporting facilities, and inconsistent coordination among implementing agencies (BARANTIN, PSDKP, and local fisheries officers). Qualitative responses highlight that many stakeholders still lack understanding of technical provisions such as minimum size requirements and restocking obligations. The study concludes that while the regulatory framework is normatively comprehensive and aligned with sustainable fisheries principles, its practical effectiveness remains constrained by institutional and socio-cultural factors. Strengthening community engagement, increasing inter-agency coordination, and enhancing enforcement capacity are crucial to optimizing the policy’s impact on the sustainable management of lobster, crab, and blue swimming crab resources in East Kalimantan.

Abstract

The practice of fishing using bombs (blast fishing) presents a serious threat to marine ecosystems and the sustainability of coastal communities' livelihoods. Law enforcement against these violations faces complex challenges, especially in large areas of water with limited fleet and patrol personnel. Perpetrators who move quickly and change locations, coupled with the lack of reports from the public due to fear or social ties, further complicate enforcement efforts. In addition, access to hidden locations and coordination between law enforcement agencies that are not optimal are also the main obstacles. Global studies confirm that the lack of effective law enforcement and adequate governance is a significant driver of these destructive practices, even beyond socio-economic factors. Therefore, a comprehensive strategy is needed that includes strengthening integrated marine patrols on a regular basis, imposing strict sanctions, increasing socialization of the dangers of fish bombs, and the active involvement of coastal communities as supervisors. A synergistic approach between law enforcement officials and local communities, combining prevention and joint management measures, is key to achieving effective marine conservation and sustainable management of fishery resources.
