Abstract

Seagrass ecosystem is a coastal ecosystem where seagrass grows as the dominant vegetation and can live permanently below sea level. Of course, the existence of human activities that do not care about the coastal environment has an impact on changes in seagrass communities in supporting coastal ecosystems. This study aims to determine the structure of the seagrass community in Terkulai Island Waters, Tanjungpinang City, this research was conducted in May 2023. Determination of the sampling point was carried out using the purposive sampling method with 4 stations that have seagrass distribution. Observation of seagrass was carried out using the modified line transect method where the line transect was placed at the starting point where seagrass was found until the end point was not found, the transect placement was chosen based on the longest area of the seagrass stretch and as a benchmark the transect placement was squared 50 x 50 cm then each line transect length was divided by 10% to get the squared distance between transects. The results of the study found 3 types of seagrass in the waters of Terkulai Island namely Enhalus acoroides, Thalassia hemprichii, Halophila ovalis. Seagrass Thalassia hemprichiii has the highest density when compared to other seagrass species with density values ranging from 764 to 1928 shoots/m2. If categorized, the value of seagrass cover at each station is included in the medium category. For seagrass biomass the Enhalus acoroides type is larger when compared to other seagrass species. The results of PCA (Principal Component Analysis) showed that seagrass cover was closely related to the environmental parameter characteristics of depth, brightness, salinity.

Abstract

Riau Islands Province has a larger water area than its land. This large water area then began to be managed with the establishment of a conservation area known as the Bintan Island Eastern Waters Tourism Park. The vast waters in the Riau Islands are thought to also have high diversity, one of which is Elasmobranchii species. The purpose of this study is to identify the species diversity and conservation status of Elasmobranchii from the catches landed by local fishermen in Bintan Island Eastern Waters Tourism Park. The method used in this study is a survey method, which is descriptive to determine the description of the results of the identification of species diversity and conservation status of Elasmobranchii. From the results of this study, 12 species and 8 families of 72 Elasmobranchii individuals were identified, with a diversity index value of H' = 2.21 (medium), uniformity index E = 0.89 (very good), and dominance index C = 0.14 (low) or no dominating species. From the conservation status analysis, it was found that 42% or 5 out of 12 Elasmobranchii species were categorized as Vulnerebel, 25% (3 species) were categorized as endangered and 8% (1 species) were categorized as critically endangered, 75% of Elasmobranchii species landed at the study site had a decreasing population status.   Keywords: Bintan, Elasmobranchii, Diversity, Conservation

Abstract

Seagrass restoration practice of transplanting grown seagrass from a donor to the planting site is discovered to disrupt the existing ecosystems. An alternative method includesthe use of seedlings, which requires a protected germination environment to survive. At the initial stage, the seedlings need adequate space for growth and expansion of root systems. However, cultivating seagrass seedlings in aquariums is challenging due to limited space. Therefore, this study aimed to investigate the growth and development of aquarium-cultured seagrass seedlings and evaluate the impact of different spacing on growth. Seedlings were cultivated in the laboratory under 2 treatments, each lasting 3 months. Enhalus acoroides seedlings collected from Dompak Island, Tanjungpinang, were used with varying planting distances for each treatment. The results showed that Treatment A (4 cm spacing) had a lower survival rate (66.73%) compared to TreatmentB (1.5 cm spacing) (97.78%) due to a fungus outbreak.However, Treatment B had slower growth than A, suggesting potential problems with water quality and increased competition for resources in denser plantings. In this study, the significance of planting spacing was outlined and a statistically significant difference was discovered in seagrass growth between various treatments (P0.05). A rapid growth rate of 2.08-3.02 mm/day was observed in leafs, which exceeded the value observed in previous investigations conducted under similar conditions and species. It was important to acknowledge that leaf length was also 17.5-21.6 cm, exceeding the values observed in another experiment using lab-cultured E. acoroides. Root lengths were comparatively shorter (7.6-8.2 cm), which signified the dynamic nature of seagrass development. In conclusion, addressing environmental conditions and optimizing planting spacing, was essential for sustainable growth.Keywords:EnhalusGrowthSeagrassSeedlingsSpacing

Abstract

Seagrass ecosystems have an essential function as a feeding, spawning and nursery areas for various marine biota, etc. There are threats to the sustainability of seagrass ecosystems' biodiversity, one of which is the dumping of garbage into the sea, which causes damage to coastal ecosystems. This study aimed to determine the species and cover of seagrass ecosystems and the type and density of marine debris in seagrass ecosystems in the waters of small islands of Tanjungpinang City. There are three stations: Dompak Island, Penyengat Island, and Los Island. This research was conducted in May-June 2023. Seagrass cover data was collected using the line transect method with a quadrat transect of 50 cm x 50 cm to observe the species and cover. Data collection on marine debris in the seagrass ecosystem was taken on transects with an area of 100 m x 100 m. Marine debris obtained is then grouped by type to calculate density and weight. The types of seagrasses found include Enhalus acoroides, Thalassia hemprichii, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis, Halodule pinifolia, Halophila ovalis, and Syringodium isoetifolium. The highest total seagrass cover is found on Los Island, with a value of 25.81% classified as poor with a sparse cover category. The types of marine debris found are plastic, glass, rubber, wood, and its derivatives. According to the number of pieces, the highest density of marine debris is plastic waste, resulting in 0.0079 items/m2, and the weight density is 0.0528 grams/m2 found at Los Island.Keywords:biodiversitydebrisplasticseagrasssmall island
