Seagrass bed is a true flowering, fruiting, leafy and rooted plant that grows on a muddy, sandy to rocky substrate that lives submerged in shallow and clear sea water, with good water circulation. This study aims to determine the diversity of seagrass species, sdeagrass unioformity, dominace index, seagrass density, and percentage of seagrass cover, ass well as the effect of substrate types on seagrass conditions in the waters of Maitara utara village and Maitara induk village. This research is divided into two observation stations based on the distribution of seagrass,namely station I in Maitara selatan village and station II in Maitara induk village. At each station it is divided into three lines an three quadrants, the distance of 60 meters where on each line the transect line from the coastline to the sea is 60 meters long, while the distance of each quadrant I, II, III with a distance of 20 meters. Measurement of oceanographic factors includes traffic, turbidity, current velocity, temperature water pH and sediment. Furthermore, it was tested by simple linear regression using excel version 2010 to determine the relationship between seagrass and the types of sediment grains. The results of this study indicate that the conditions of seagrass density at stations I and II belong to the scale of dense conditions (125-175) and very dense (> 175). The Diversity Index at both stations is classified as moderate diversity. The seagrass uniformity index at stations I and II is classified as a high level of uniformity, and the dominance index obtained at stations I and II is classified as a low level of dominance. The correlation between substrate grain diameter and seagrass at stations I and II does not have a strong linear relationship, the r (correlation) value is obtained at station I of 0.037 and at station II of -0.145 which means that the seagrass density has a negative correlation with the type of substrate grain

The objectives of this study were: 1) To take an inventory of seagrass species in Tafamutu coastal waters, 2) To determine the density, species diversity and dominance index of each seagrass species in Tafamutu coastal waters, 3) To measure temperature, salinity and visually observe the substrate. . The method used in sampling is the line transect method (Krebs, 1999) consisting of 1 station with three tracks. Density analysis using the formula according to Brauner and Zan (1977) in Krebs. (1999), the distribution pattern using the Morisita index (Krebs), the diversity of species using the Shannon-Wiener index, (1949) in Ludwiq and Reynolds (1988) and the dominance of the index using the Simpson index (Krebs, 1999). The seagrass species found in this study There are 4 species, namely Cymodocea serruluta, Cymodecea rotundata, Syringodium isoetifolium and Enhalus acoroides. From the number of species found, there were species that were not included in the quadrant, namely Halodule pinifolia and Halophila minor. The highest density was Cymodecea rotundata and the lowest was Enhalus acoroides. The highest diversity was Cymodocea serruluta and the lowest was Enhalus acoroides while the most dominant was Cymodecea rotundata. The temperature ranges from 30 – 33 °C and the salinity ranges from 33 – 35 . The substrate consists of silt mixed with sand, fine muddy sand, coarse sand mixed with coral. Suggestions that can be given in this research are the need for studies of seagrass organisms and research on nutrient content for seagrass life in Tafamutu coastal waters.

This study aims to calculate the thickness and density of mangrove ecosystems in the waters of Maitara Tengah City of Tidore Islands and calculate the suitability of mangrove ecosystems for ecotourism in the waters of Maitara Tengah Village while the use of research is as reference material for further research activities as well as a basis for consideration in management of mangrove ecotourism areas using the concept of conservation for related agencies. The results of data collection at the two observation stations using the "line transect" method obtained the composition of mangrove species after being identified based on the characteristics of the shape of the roots, leaves, flowers and stem bark, so there were 2 types, namely Rhizophora apiculata, and Bruguiera gymnorhiza. The highest relative density value of mangrove species from the two stations was Rhizophora apiculata and the lowest relative density value was Bruguiera gymnorrhiza. The area suitability value for mangrove ecotourism obtained shows that Maitara Tengah Village is feasible to be used as a mangrove ecotourism area
