Kurnia, Try. 2021. Arsenic Analysis in the Hair of Gold Miner Alue Baro Village Meukek District, South Aceh with Inductively Coupled Plasma Mass Spectrometry Method. Thesis, Department of Chemistry Education, Faculty of Teacher Training and Education Educational Sciences, Syiah Kuala University. Supervisor : (1) Drs. M. Nasir, M.Sc., (2) Dr. Ibn Khaldun, M.Si. Keywords: Arsenic, ICP-MS, Hair, Gold miners in Alue Baro village Research has been carried out on the analysis of arsenic (As) levels by ICP-MS in Gold Miner Hair in Alue Baro Village, Meukek District, South Aceh. This study aims to determine the content of heavy metal Arsenic which is in the hair of a gold miner in Alue Baro Village. Hair sample obtained from 5 employees who work as miners and 1 resident who lives in Alue Baro Village, Meukek District, South Aceh. Sample in destruction wet using concentrated HNO3 and microwave digester at a temperature of 150℃. Rate Arsenic was measured using the ICP-MS instrument with a wavelength of 193.7 nm. The results showed that the sample code R1, R2, R3, R4, R5, and R6 successively 0.35; 0.53; 0.23; 0.28; 0.33; and 0.21 mg/kg. Whole the hair studied still has safe and tolerable levels of arsenic WHO is 1 mg/kg
