Abstract

This research was conducted on 27 April-30 May 2019 at Tiram Beach, Karambia Ampek Beach and Gosong Beach, Padang Pariaman Regency, West Sumatra Province. This study aims to determine the relationship between sediment grain size and the number of turtle eggs. The method used in this research is purposive sampling. The sampling location is divided into 3 stations, each station is divided into 5 sampling points in order to obtain 15 sampling points, of which the fifteen sampling points are the usual nesting sites for turtles. Sediment samples were taken approximately 500 grams, put in a plastic bag, then labeled and then the sample was taken to the laboratory for analysis. The procedure for analyzing the sediment grains for sand and gravel fractions used the wet sieving method, for the sludge fraction was analyzed using the pipette method. The results from the wet sieving method and the pipette method were combined and the mean size (Mz) was obtained. Measurement data were analyzed using linear regression analysis, then correlation and regression analysis to determine the form of the relationship and the strength of the relationship between two or more variables. Sea turtles will lay eggs, namely the mean size ranges from 1.13-1.8 Ø. The coefficient of determination (R2) = 0.53 and the correlation coefficient r = 0.73. This means that the coefficient of determination shows the average diameter (mean size) affects 53% of the number of turtle eggs, while the other 47% is influenced by other factors, for example vegetation around the coast..

Abstract

This study aims to provide an overview map of the pattern and speed of the tide to the ebb and flow towards the tide and bathymetric of Muda Island in estuary of Kampar River, Teluk Meranti Subdistrict of Pelalawan District. This research was conducted in September 2016 held in Muda Island in estuary of Kampar River, Teluk Meranti Subdistrict of Pelalawan District. The method used in this study is a survey method. Tidal current velocity ranges from 0.16 to 0.54 m/sec. The current direction moving toward the southwest parallel to the river flow. Flow velocity ranges recede from 0.15 to 1.09 m/sec. Moving current direction leads to northeast parallel to the river flow. Bathymetric map of Muda Island estuary of Kampar River found the same relative depth between 0.5 to 2 m on the left and right streams and others around the Muda Island and Ketam Island. Type of tidal Muda Island is a mixed - mainly semidiurnal with the value Formzahl (F) = 0.27. The current direction of Muda Island to follow the type of its tidal namely a change in the flow of 2 times, 2 times in the direction of the tide and 2 times towards low tide.

Abstract

This research was conducted from February to March 2017 in Pelawan Beach of Riau Archipelago Province which aims to study the pattern of current, tides and wave characteristics of Pelawan Beach. The method used in this research was survey method. Determination of stations for data collection, in 3 stations with 3 sampling points. The results showed that the mean of current speed at high tide was 0,48 m/sec (Southeast and East) and mean of current speed at low tide 0,46 m/sec (West and Northwest). The tide in this area is mixed tide type with dominant of semi-diurnal, which occurs twice of high tide and twice of low tide in a day. Characteristics of the waves ( height, period, length and slope) is plunging and formed beach type. The depth of the waters is sloping and shallow, ranges from 1,1 to 2,0 m. Current and wave conditions in Pelawan Beach waters are safe for coastal activity around Pelawan Beach.Keywords : Current, Tides, Wave, Pelawan Beach

Abstract

ABSTRAKThe research was conducted in May 2014, in the western part of the Rupat Strait. The aim of study was to determine the sediment material horizontally. This samples were taken using Eckman Grab from 9 sampling points. The analysis of the organic content in the sediment was also done.The results showed that the composition of the sediment in the western part of the Strait Rupat composed of lithogenous (rocks, mica, quartz ) and biogenous ( litter and Foraminifera). Lithogenous composition of rocks dominate waters and existede evenly at each sampling point. The highest percentage found in a location close to the mainland, this was suggested that the materials carried by the tide of Malacca and ebb currents of the Sungai Masjid River piled around this sampling point. In addition, the type of rock could have also come from erosion and anthropogenic activities in water around the edge.The organic matter content of sediment was highest at the sampling point close to the mangrove area. This was due to getting the supplay of organic material from the mangrove areas.Keywords: Composition, Tidal Currents, Sediment, Rupat Strait, Mangrove

AbstractThe main purpose of study was to find out characteristics of sediment and velocity of coastline change in Sungai Kayu Ara Village which is located off the Siak district, Riau. Sediment samples were collected at 3 stations in coastal area of Meskom Village in September 2019. Stations 1 and 2 are located in the residential area and Station 3 is in the vicinity of the Ara Permai Mangrove Tourism Forest. Coastline change analysis used image data by Landsat 5 TM (1997 and 2009) and Landsat 8 LDCM (2019) which processed by ArcMap10.3..Sungai Kayu Ara village is characterized by sediment fine silt and very coarsed skewed indicated that abrasion and sedimentasion influenced of current and wave. Moderately sorting indicated that the sediment coastal of Sungai Kayu Ara village has rather stable environmentally. Interpretation of image data indicated that the coastal area has been abraded at station 1, that is 84,268 meter/year seen from 1997 to 2019.Keywords: Sediment, Coastline change, Abrasion, Remote Sensing.

Abstract

ABSTRACT The aim of this research is to know the condition of coral reefs including the live coral cover of the waters of Cempedak Island Bintan.This research had been conducted in the waters around Cempedak Island Bintan in May 2018.The research station is divided into 3 stations based on environmental characteristics with a depth of 5 meters.Research stations include Eagle Rock, near Jetty and Deadmans Beach. The data of coral reefs were collected by using Underwater Photograph Transect (UPT) method. Data were analyzed using Coral Point Count with Excel extension (CPCe) application.The results showed that coral cover on the study sites ranged around 23.87% to 47.87% which can be classified as poor  to moderate category sequentialy.At each station can be seen a high percentage is in station III with value 47.87%, whereas at station II coral percentage is low or bad with value 23.87%.The low coral cover is caused by the strong ocean currents causing sediment staggeration so that the sediment covers the coral surface and because of the current, the number of races and dead corals found with algae to cause the coral is damaged as in station II. The quality of water such as temperature, salinity, pH and visibility of the research location was good for coral reefs recovery and growth. Keyword: Coral reef, Cempedak Island, Underwater photograph Transect (UPT),  Current Speed
