Bottom Sediment Analysis at Lhok Seudu Beach, Aceh Besar

Abstract

The research with the title Basic Sediment Analysis of Lhok Seudu Beach, Aceh Besar was conducted from March to April 2023. Lhok Seudu Beach is a bay beach in the area affected by the 2004 tsunami.  This study aims to determine the characteristics of sediments as a basis for geological oceanography studies. The method used serves to analyze the shape of the bottom sediment with granulometric analysis. Granulometric analysis itself uses the sieve analysis method or multilevel screening to determine the results. The results of this study are the largest mean sediment of each station in each grain size is the type of medium sand with an average percentage of 0.2794029% and the smallest mean is the type of coarse silt with an average percentage of 0.05309625%. The conclusion obtained in this study is the divergence of the sediment in each station. The conclusion obtained in this study is that the differential found at EBA and WBA is influenced by topography and sediment transportation on sediment characteristics.
