This research was carried out on Moti Island, Moti District, Ternate City, North Maluku Province for 6 months, April - September 2021. This study used mixed research methods between quantitative and qualitative research with the aim of complementing the description of the study results regarding the phenomenon being studied and to strengthen research analysis. Data collection consisted of interviews, questionnaires and field observations. The assessment of plant success was carried out through a sampling technique using the Systematic Sampling with Random Start method, ie the first plots were made randomly and the next plots were made systematically. The results showed that the plant height growth (Growth rate) in Tafaga Village in an area of 100 x 100 meters with an average of 31 cm. While the area is 100 x 50 meters with an average of 49 cm. Meanwhile, in Figur Village, the general population experienced good growth with an average of 63 cm. The success of rehabilitation activities in Tafaga Village was very low at 9% and 21% so that they were not successful overall. While in Figur Village it is considered successful with 80% success.

This study was conducted with the aim of knowing the composition of gastropod species that live in the seagrass area of Tafaga and Figur coastal waters, Moti Island and to determine the structure of the gastropod community which includes density, diversity, dominance and species evenness. The sampling technique was carried out using the 50x50 m block area method. The composition of gastropod species found in coastal waters of Tafaga (station 1) was 6 species and coastal waters of Figure (station 2) were 17 species. The highest density of gastropod species in station 1 was found in the Nassarius pullus species and the lowest in the Naria erosa species. Meanwhile, in the station 2, the highest density of gastropod species was also found in the Nassarius pullus species and the lowest in the Strombus lentiginosus species. The diversity of gastropod species at station 1 is low and there are species that dominate and the distribution of species is quite even. While at station 2 the species diversity is moderate and no species dominates and the species distribution is evenly distributed.

. Seagrass ecosystem is one of the coastal ecosystems that can provide food supply and improve the living standards of coastal residents. The objectives of the study were to determine the composition of the seagrass species on Toduku Island, to determine the composition of the seagrass biota species, to determine the community structure of seagrass species and associated biota including species diversity, species dominance and species density and to determine the interaction pattern of the utilization of seagrass fisheries resources by the community around Toduku Island. . The method used is field observation and Participatory Rural Appraisal (PRA). The composition of seagrass species in Toduku Island are Enhalus acoroides, Thalassia hemprichii, Halophila minor, Cymodocea rotundata, Halodule pinifolio, and Syringodium isoetifolium. The composition of the biota that inhabits the seagrass beds of Toduku Island consists of fish, crabs and macrozoobenthos (Holothuroidea, Echinoidea, Asteroidea, gastropods, bivalves). The diversity of seagrass and biota species is moderate, there is no dominant species and the distribution of each species is very even. The pattern of interaction in the use of seagrass resources has been patterned for generations. The forms of utilization activities carried out by the community include taking mollusks (snails, clams), echinodes (sea cucumbers, sea urchins), catching fish and crabs.

Mangroves is one of the producers of nutrients, one of which is nitrate in estuary waters. Nitrate content in waters naturally comes from weathering or decomposition of plants and the remains of dead organisms. This study aims to analyze the relationship between mangrove density and nitrate in the mangrove ecosystem on Manomadehe Island, South Jailolo, West Halmahera. Data collection was carried out from April to May 2022. Analysis of sediment samples was carried out at the LPPM Basic Laboratory, Khairun University. The data analysis method used is simple linear regression. The results of the analysis of the highest species density at ST3 were 4100 trees/ha-1 and the lowest was ST1 at 1900 trees/ha-1. The highest nitrate concentration was found at ST3 at 3.58 mg/kg and the lowest at ST1 at 0.83 mg/kg. The strong ridge pattern (r) between the variable density and the nitrate concentration was 88.90%. The regression coefficient of 1.8998 indicates that the density of species has a positive relationship with the average concentration of nitrate in the sediment, where every 1 unit decreases in the value of mangrove species density will affect the decrease in the average nitrate of -1.33812 units.
