Survei Geolistrik Resistivity Aturan Schlumberger Untuk Studi Air Bawah Tanah Di Lahan Pertanian Palawija Marpoyan Damai
Marpoyan Damai sub-district has the potential as a secondary crops agricultural
land. However farmers in the area have difficulties in getting water in dry season
for their farming activities. Because of this, study on potential ground water
location in the area is very important. This study was aimed to identify the depth
of the subsurface structures around the agricultural area. The data were taken from
two paths in Marpoyan Damai District, namely at coordinates 0o26’44.232” LU,
101o26’4.866” BT and at coordinates 0o26’44.210” LU, 101o26’4.092” BT. Data
processed from the progress software shows while at coordinate 0o26’44.232” LU,
101o26’4.866” BT, there is one aquifer layer in the fourth layer which have a
resistivity value of 80.76 Ωm with a thickness of 6.52 m and while at coordinate
0o26’44.210” LU, 101o26’4.092” BT, there is one aquifer layer in the second layer
which have a resistivity value of 80.45 Ωm and a thickness of 9.99 m. The
lithology data of each path shows the water flow pattern strats from line one to
line two. The result of aquifer potential analysis shows that the underground water
reserve in secondary crops agricultural land, Marpoyan Damai District, Pekanbaru
City is 174.3 x 103 m3. While the measurement of pH analysis shows that the pH
is acidic which is 3.85.
