Abstract:
Water is a very important substance for human life therefore, more water is needed. Peat
water is surface water resulting from the accumulation of plant material residues in a large volume
with a pH ranging from 3-5. In general, this makes peat water does not meet the requirements for
clean water quality, however, in the case of water shortages it forces peat water to be processed into
clean water. Peat water treatment must begin with measuring what content is in the water. Peat water
was obtained from a large area of peatland in the Labuh Barat sub-district, Payung Sekaki subdistrict.
The peat water was collected from 36 points from a depth of up to 2 meters. Peat water
content was determined by measuring the susceptibility value using Quincke method and AAS test to
classify mineral types and identify the process of mineral transfer in peat water then susceptibility
mapping was carried out using the surfer application which is non-destructive method. The results of
the magnetic susceptibility values of peat water samples in the Labuh Baru Barat sub-district, Payung
Sekaki sub-district are 1.8465 x 10-5 to 1.962 x 10-5, with a density of 992,000 Kg/m3 to 998,000
Kg/m3. Based on the results of the magnetic susceptibility and the AAS test, it was found that the
sample was paramagnetic with the heavy metal content of Mn, Mg and Cr still categorized as safe
and not exceeding the standard threshold.
