Abstract

The Ecopath mass-balanced model was employed to elucidate the trophic structure and interaction, energy flow, and ecosystem properties of the coral reef ecosystem in the coastal area of Ternate Island. The model comprised 30 functional ecological groups, of which 29 were living groups and one was a group of detritus. The trophic structure of the model exhibited a range of values, from 1.0 for primary producers and detritus to 3.81 for the top predator. The resulting trophic aggregation comprises six effective trophic groups, with the largest energy flow originating from zooplankton and benthic organisms in trophic level II. The transfer efficiency is predominantly derived from detritus organisms, in comparison to that derived from phytoplankton as the primary producer. The ratio of total primary production per total respiration indicated that the coral reef ecosystem was at a developmental stage. The coral reef ecosystem exhibited a low ecological efficiency for the fishery gross efficiency. Mixed trophic impact analysis indicated that predators exerted a negative impact on their prey, whereas planktonic organisms exerted a positive impact on the majority of fish functional groups. The comparison of the model with other studies provided information that could inform the development of appropriate fisheries management guidelines for this area based on ecosystem properties.Keywords:Coral reef ecosystemEcopathEcosystem propertiesTernate IslandTrophic interaction

Abstract

Bruguiera gymnorrhiza fruit has considerable potential as an alternative food resource with nutritional and economic value; however, its utilization by local communities on Maitara Island remains limited. This Community Partnership Program (PKM) aimed to implement the processing technology of Mangrove Boba Drink (MaBo) through a partnership between a higher education institution and a community group to diversify mangrove-based food products and strengthen the local creative economy. The program was conducted in Maitara Utara Village, Tidore Islands City, Indonesia, using a participatory approach involving community outreach, training on raw material selection, mangrove flour processing, boba production, preparation of three MaBo variants (MaBo Neutral, MaBo Full, and MaBo Local), sensory evaluation, and technical assistance for the Marirasa Creative Group. The results showed that all participants successfully mastered the MaBo processing technology and produced products that were well accepted by the sensory panel, with all attributes receiving scores within the "liked" to "highly liked" categories (4–5). Among the three variants, MaBo Full achieved the highest overall preference, followed by MaBo Local and MaBo Neutral. The program enhanced the knowledge and technical skills of the community in processing mangrove fruit into innovative products with the potential to support locally based creative enterprises while strengthening partnerships between higher education institutions and community groups.
