Abstract

This study was conducted in February 2016 in the strait between Belakang Padang Island and Sambu Island of Batam City in Riau Island Archipelago Province. The aim of the student has to understand the environmental deposition of Pulau Belakang Padang waters based on the analysis of surface sediments distribution. Surface sediment samples were taken using Eckman grab from 20 sampling points, to analyze the grain size and sediment composition. In general, the sediment characteristics of the study area is dominated by the fraction from fine to very fine sand. Environmenal deposition can be devided 4 groups. The first group has a weak current and very unstable oceanographic condition, the second group has a mean size that is more rugged and has lower percentage of clay fraction, third group was characterized by stronger current and slightly more stable oceanographic condition and fourth group has oceanographic conditions with the most strong and more stable current system.Keyword: Sediment, Distribution, Belakang Padang, Sambu, Batam

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
