Analysis of Mercury Content (Hg) in Lake Payawan Gold Mining Area Tumbang Panggo Village, Tasik Payawan District Katingan Regency

Abstract

Field activities conducted to determine the level of mercury content in the water flow of Lake Payawan,
Tumbang Panggo Village, Tasik Payawan District, Katingan Regency, Central Kalimantan Province
based on laboratory test results to obtain the results of mercury content in upstream to downstream of
Lake Payawan. From this research, it is necessary to test the quality of water in the laboratory in order
to analyze the water quality parameters so it can be known mercury content (Hg) in Lake Payawan
water flow. From the test results on 6 points river water samples in the laboratory of the Industrial
Research and Standardization Center of Banjarbaru City showed the highest mercury content found in
sample number 3 with P. 2076 test code taken at the location of the middle Lake Payawan Tasik
Payawan District with mercury levels located At a rate of 0.069 μg / l or 0.000069 mg / l, this reflects
the presence of other factors that may also affect the level of mercury content in Lake Payawan flow.
