Abstract

Batakan Beach is a beach located in Panyipatan District, Tanah Laut Regency. The beach was inaugurated in 2019 by the Tourism Office and continues to be managed until now. The coast of the beach is surrounded by white to cream-colored sand. This study aims to determine the magnetic susceptibility value and heavy metal content in the sand of Batakan Beach, Panyipatan District, Tanah Laut Regency. This study was conducted at 1 location with 6 sample points on Batakan Beach using the environmental magnetism method with the Bartington MS2 susceptibility meter and X-Ray Fluorescence (XRF). The average magnetic susceptibility value ranged from 6 x 10^-6 m3/kg to 14.43 x 10^-6 m3/kg. Heavy metals contained in sand samples on Batakan Beach, several elements have passed the heavy metal threshold in sand at this location such as Al, Ti, V, Cr, Fe, and As. At this location, the correlation coefficient value varies at each point. Strong correlations are Fe, Al, Ni, Cr, Eu and Ti.
