The Artisanal and small-scale gold mining (ASGM) activities at Sekotong District, West Lombok, West Nusa Tenggara have a negative impact on the environment. The use of mercury (Hg) and cyanide (CN) in the process of extracting gold can cause pollution to soil and plants. This study aims to determine the content of mercury and cyanide in soil and plants around gold mining. The research method used is descriptive explorative. The research sample was taken purposively at 6 locations and sample analysis at the Chemical Laboratory of Universitas Brawijaya. The results showed that the Hg content in surface soil ranged from 2.90-26.94 mg/kg, Hg in soil with a depth of 30 cm ranging from 3.48-53.86. HCN content in surface soil ranges from 63.93 to 104.08 mg/kg, HCN in soil 30 cm deep ranges from 66.59-106.55 mg/kg. The content of mercury and cyanide in rice plants (Oryza sativa), cassava (Manihot esculenta), banana (Musa paradisiaca), chili (capsicum sp), turi (Sesbania grandiflora), mango (Mangifera indica), mangrove (Rhizophora apiculata), and grass (Eleusine indica). The Hg content in these plants ranges from 1.23 to 8.15 mg/kg, HCN content ranges from 18.41 -52.85 mg/kg. Referring to the standards set by WHO and Health of the Republic of Indonesia Number 57 of 2016, soil and plants have polluted and have a negative impact on other living things.
