Abstract

ABSTRACTSeagrasses are plants adapted to live fully in the marine environment. Seagrass plays an important role in coastal areas due to critical habitat for many kinds of marine animals such as fish, mollusks, crustaceans, echinoderms. This study was conducted from March 2018- May 2018 at the Seagrass Beach Conservation Area of Trikora Regency of Bintan Riau Island which aims to know: the density of each seagrass species and the change of seagrass area based on the mapping in 2006-2018. Sampling is done at three stations, namely Station I residential zone, Station II natural seagrass zone and Station III zone tourist resort. Sampling and measurement of water quality was done by using quadratic transect. The results obtained 8 (eight) seagrass species that was of Cymodoceaserrulata, Enhalusacoroide, Halodulepinifolia, Haloduleuninervis, Halophilaovalis, Syringodiumisotifolium, Thalassiahemprichii, Thalassodendronciliatum. The highest seagrass density obtained at Station II is 487.11 tegakan/m2 in the low seagrass areas. Referring to the criterion of seagrass density according to Braun-Blanquet that seagrass with density> 175 is very tight. The result of the change of seagrass area in 2006-2018 happened addition area of 122 ha, thus there is influence from TRIMANDES (activityTrikoraSeagrass Management Demonstration Site)onseagrass community.Keywords: Seagrass, Density, Area, Trikora

Abstract

                                                      Abstract Teluk Pambang Village in Bengkalis Regency which is located in the Riau Province is one of the villages that is very vulnerable to abrasion, because it is an area that faces the Malacca Strait and has a peat texture. This study examined how much the abrasion rate and the extent of the shoreline changes that occurred in Teluk Pambang Village by using Landsat satellite imagery data in the last 20 years. Landsat satellite image data processing consists of geometric calibration, image cutting, image sharpening and digitization so that the coastline position for each data year is obtained. Changes in the coastline from year to year are analyzed by the process of overlapping data for a certain period of time. The results of this study indicate that Teluk Pambang Village experiences abrasion with varying levels of abrasion. changes in coastline Teluk Pambang Village The last 20 years from 1997 - 2017 there was an abrasion of 4.18 m / year and sedimentation of 5.33 m / year. The change of coastline in Teluk Pambang Village is abrasion of 418.88 m and sedimentation area of 218.28 m. There is a positive relationship of current velocity with abrasion velocity and abrasion velocity relationship with wave energy obtained from linear regression results on the graph.Critical beaches that experience maximum abrasion rates are recommended to be immediately addressed so that abrasion does not continue in subsequent years.Keywords: Abrasion, Accretion, Landsat Image, Coastline, TelukPambang Village

Abstract

This research is expected to find out how abundance and distribution of blood clams (Anadara Granosa) in coastal waters of Mekarbaru village, Kepulauan Meranti District. In good conditions or during the season in a particular month there is more capture compared to when it is not in season. Analyze using descriptive analysis research methods using survey methods. The materials used in this study were blood clam samples (A.granosa), and aquades for tool rinsing. The results of this study can be concluded that the average abundance of blood clams of A. granosa in the coastal waters of Mekarbaru Village, Kepulauan Meranti District is different. The highest average blood clam abundance was found at station III which was 21.86 Ind / m2 and the lowest was at station II which was 19.63 Ind/m2. The size distribution of blood clams A. granosa can be seen that dominating is the size of <25 mm (small), while the size of 25-30 mm (Medium) is only found at each station. The abundance of small blood clams A. granosa is influenced by the content of sediment organic matter and water quality in the coastal waters of Mekarbaru Village, Kepulauan Meranti Regency.
