Abstract

The Totok and Makalo River estuaries in North Sulawesi, Indonesia, serve as vital habitats teeming with fish biodiversity, supporting coastal ecosystems and local fisheries. This study aimed to identify fish species and elucidate their genetic relationships through DNA barcoding of the Cytochrome Oxidase I (COI) gene. Fish samples were collected from both estuaries using nets and traps, followed by molecular analysis involving polymerase chain reaction (PCR) amplification and Sanger sequencing. The results confirmed the presence of 11 fish species, including Osteomugil engeli, Polydactylus plebeius, and Gazza minuta, with high identification accuracy (over 98% sequence similarity to reference databases). Notably, Paracentropogon rubripinnis and Nematalosa come were recorded for the first time in North Sulawesi waters, expanding the known distribution of these species. Significant genetic variation was detected in P. rubripinnis, potentially indicating cryptic speciation or local adaptation to environmental gradients. Phylogenetic analysis revealed close genetic affinities between certain species and populations from Taiwan and Bangladesh, suggesting historical migration patterns or shared ancestry, possibly facilitated by ocean currents. These findings underscore the rich genetic diversity in these estuaries, which are influenced by factors like salinity, temperature, and anthropogenic pressures. The study emphasizes the urgency of conservation strategies, including habitat protection and sustainable fishing practices, to preserve biodiversity and maintain ecosystem services. By providing baseline data on species composition and genetic connectivity, this research contributes to broader efforts in marine biodiversity monitoring and informs policy for coastal management in Indonesia's biodiversity hotspots.

Abstract

Maneke is one of the local wisdom in Sangihe Islands Regency, inherited from the ancestors of the people of Sangihe. Maneke contains the norms and values of life and customs to keep the mutual relationship between humans and nature. This local wisdom, however, has gradually become extinct. The aim of the research was to describe the Maneke as a local wisdom in Sangihe Islands. Sangihe Island Regency is one of a cluster of islands located in North Sulawesi province with 150 islands, 26 inhabited and 79 uninhabited islands. There are two islands on the cluster of uninhabited islands located in two Districts in Sangihe. The focus of this research is done on the Batunderang Island in the Sub-district of South Manganitu and Para Island in the District of Tatoareng. This study used a qualitative approach to the design ethnography emphasizes the natural setting to see, learn, express and understand how to observe, and observations with in-depth interviews and conduct focus group discussions with community members, traditional leaders, public figures, figures from religious leaders and members of the implementation group of Maneke. Maneke is a socio-cultural system that has a socio-cultural elements contained in the components of the superstructure ideology, social structure and infrastructure material. Maneke is the component of the superstructure ideology because it has cultural values and norms into view, knowledge, activity and behavior patterns which are actualized in the traditions, customs, rituals beliefs or religion.Keywords: local knowledge, Maneke, marine tourism, Sangihe Island.

Abstract

Seagrass ecotourism is a tourism activity based on seagrass ecosystem as an educational tour by seeing the ecology of seagrass meadows and associated biota. Conservation awareness and improving community welfare, seagrass ecotourism is a nature-based tourism strategy with the aim of environmental conservation and containing aspects of community education and culture. Determining the sustainability status of seagrass ecosystem management is very important as a basis for future policy planning. The sustainability of seagrass ecosystems needs to be protected, so a policy strategy is applied in sustainable seagrass ecosystem management. The objectives of the study are: 1) determining the sustainability status of ecotourism-based seagrass ecosystem management based on ecological, economic and social dimensions, 2) determining the policy strategy for ecotourism-based seagrass ecosystem management. The results of the study obtained the sustainability status of ecotourism-based seagrass ecosystem management based on ecological dimensions is quite sustainable while the economic and social dimensions are less sustainable. The strategy for sustainable policy for managing seagrass ecosystems based on ecotourism on Maitara Island, Tidore Islands, namely education about seagrass ecosystems for the community, managing seagrass ecosystems based on ecotourism, increasing seagrass rehabilitation programs, maximum limits for carrying capacity of seagrass ecotourism, training for developing managers of seagrass ecotourism based on ecosystems, increasing job opportunities and business opportunities, legality of seagrass areas as conservation areas in the tourism utilization zone category and strengthening laws and institutions.Keywords:analysismultidimensionalsmall islandsustainabilitytourism
