Abstract
Landslides problems that often occurred at Mertelu Village, Gedangsari District,
Gunungkidul Regency, DIY are caused by several factors. In addition to the fact that the village
is located in a fairly steep area, there is also a slip surface from the existing soil type. The
purpose of this research is to gather the slip surface information based on resistivity method
using Dipole-dipole configuration. The initial stage is done by taking 4 representative lines,
which each line is 300 meters long, spaced 20 meters and using n = 1-8. The results showed that
rock resistivity varied from 2 to 200 Ohm-m also divided into very low, low, medium and high
resistivity. The interpretations are very low resistivity (2-8 Ohm-m) as claystones and or
siltstones, low resistivity (8-20 Ohm-m) as muddy sandstones, medium resistivity (20-50 Ohmm)
as
sandstones
and
high
resistivity
(> 50
Ohm
–m)
as
massive
sandstones.
In
general,
the
bedding
begins
with a
very
low
resistivity
at
the
top
and
high
resistivity
at
the
bottom.
The
slip
surface
is
marked
as
a
very
low
resistivity
which
lays
above
a
higher
resistivity.
The
landslide
analysis
indicates
that
the
Gedangsari
area
is
dominated
by
rotational
landslide.
