Abstract

Pangandaran has high potential in the tourism and fisheries sectors. Marine resources that are open access and can be used by anyone cause the sustainability of resources to be threatened due to over-exploitation. Traditional fishermen are one of the livelihoods owned by the majority of coastal communities, especially in the Pangandaran Coastal area. However, fishing activities have not been carried out wisely, and become a threat to the sustainability of sustainable marine biota. Small fishermen get by-catch in the form of protected marine life and are included in the IUCN Red List and the CITES Appendix list. This research was conducted to find out the species of marine biota with important conservation status or included in the status of the IUCN red list and the CITES Appendix list caught and traded in the coastal areas of Pangandaran Regency. The research was conducted using field observation method with purposive sampling technique in 2 locations; the east coast and the west coast of Pangandaran. There are 47 fish species found in all research sites with conservation status not evaluated (12.8%), least concern (83.0%), near threatened (2.1%), vulnerable (2.1%), and included in CITES Appendix II (2.1%).

Abstract

Kepulauan seribu archipelago is home to Kelapa Dua Island, a potential marine tourism destination and habitat for diverse marine life. The survival of marine biota hinges on suitable physical and chemical water parameters, encompassing temperature, pH, salinity, and dissolved oxygen (DO). This study aims to evaluate water quality and litter distribution on Kelapa Dua Island within Kepualauan Seribu National Park. Results reveal that the water quality largely aligns with established standards; however, specific points surpass limits, notably lower salinity at stasion 3 (26%o), and higher pH at station 2 (9.35). Despite meeting quality standards, the island's status as a populated area and tourist destination raises concerns about potential alterations to water quality. Furthermore, observations on litter distribution indicate a status categorized as B (0-4/m) and C (4-10/m), highlighting a relatively low level of litter presence. The interaction of human activities, both as inhabitants and visitors, may contribute to fluctuations in water quality. Understanding these dynamics is crucial for sustainable management, ensuring the preservation of Pulau Kelapa's ecological integrity as a cherished marine environment and tourist attraction. This study provides insights into the delicate balance between human interactions and environmental preservation in the context of Pulau Kelapa, Kepualauan Seribu.Keywords:Water qualityLitter DistributionKelapa Dua IslandKepulauan Seribu
