Characteristics of beach and foreshore sediments at the coastal of Carita Beach, Pandeglang, Banten

Coastal morphology and dynamics influence the sediment transport process from land to coast and sea. A study of the distribution of sediment types was carried out on the beach and foreshore of Carita Beach, Pandeglang Banten, to provide an overview of the sediment transport and deposition processes based on sediment grain size distribution. Sediment samples were collected: nine from the foreshore and six from the beach. The sediment grain size was analysed using the fractionation method with sieving and pipetting, and the organic material content was analysed using the Loss on Ignition (LOI) method. Aggregations and statistics of the sediments were analysed using the Gradistat program. water content (%) of the sediments collected ranges from 10 - 65 %, the highest at the foreshore station (SL4) and the lowest at the beach station (SP1). The grain size (%) of the sediments collected had 11 categories, from gravel to fine clay. The total organic matter (%) in foreshore sediments is low, while that on the beach is very low. Statistically, the sediment distribution shows good sorting, high variation in skewness, and leptokurtic dominance
