Abstract

ABSTRACTSeagrass beds have an important role as the main source of primary productivity or organic matter producers, habitat for various biota, nursery grounds, spawning grounds, food sources for rare biota, and support for the diversity of marine biota species, as well as the economic value of seagrass ecosystem services. This study aims to determine the ecological index and distribution pattern of seagrass in the Banda Sea Aquatic Tourism Park (TWP). The method used is a line transect with a quadrant size of 50 cm x 50 cm that is placed perpendicular to the shoreline. The results showed that the seagrass diversity index at the study site consisted of 7 types of seagrass, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Halophila ovalis, and Syringodium isoetifilium. The diversity index is categorized as moderate with a value of H' = 0.01-0.05, and a uniformity value of 0.71 has a high uniformity, which means that the number of individual species from one species to another is not much different from a stable environmental condition. The distribution pattern of seagrass with Id 1 is a grouped category. The physicochemical parameters obtained were in accordance with the growth of seagrass life.Keywords: Banda sea, Distribution pattern, Diversity, Dominance, Seagrass, Uniformity

Abstract

ABSTRACTSalinity is the total concentration of ions found in water. Salinity is important for the survival of organisms. Almost all marine organisms can only live in areas that have small changes in salinity. The aim of this research is to determine the distribution pattern of salinity in Spermonde waters in 2022 and to find out a comparative picture of the salinity distribution pattern on Kapoposang Island, Samatellu Lompo Island, Kuninggareng Lompo Island and Lanyukang Island in Spermonde waters in 2022. This research was conducted from August to October 2023 in Hasanuddin University Makassar, Makassar City, South Sulawesi Province. Research was conducted at the Indraja Laboratory, Faculty of Marine and Fisheries Sciences. The data used was satellite image data, namely CMEMS satellite image. The pattern of salinity distribution in Spermonde Waters with an average value of 34.04 ppt is the highest salinity in August, and for the average value of salinity distribution of 32.52 ppt is in January. The comparison pattern of salinity distribution in 2022 on Kapoposang Island, Lanyukang Island, and Samatellu Lompo Island has the same average value, namely the lowest January and the highest August, except for Koninggarang Lompo Island the highest average value is in September and the lowest is in January.Keywords: Salinity, Kapoposang Island, Lanyukang Island, Koninggareng Lompo Island, Samatellu Lompo Island
