This research focuses on the granulometric analysis of coastal sediments zone in Lampuuk-Lhoknga Beach, Aceh Province. A total of 11 stations along Lampuuk-Lhoknga Beach located in swash zone are determined as locations for data collection. The sample sediment was collected in November 2018. The selected station was divided into two zones namely the upper swash zone (USZ) and lower swash zone (LSZ). The sampling technique was carried out by using a vertical coring method in order to get a sediment layer with a thickness of 5 cm from the surface. Each sediment sample was wetly sieved to obtain a weight distribution percentage based on the sieve size. Sediment statistical analysis of each sample was based on the Folk and Ward Method. The results of the study show that the average conditions of Lampuuk sediment in the upper swash zone are medium sand; Moderately Well Sorted; Symmetrical; and Mesokurtic. In Addition, at the lower swash zone is found a medium sand; Moderately Sorted; Coarse Skewed; and mesokurtic. The beach morphological diversity has resulted in a variation of statistical parameters along the shoreline at Lampuuk and Lhoknga.
