Abstract

Water is a very important natural resource that is needed by all living things in all their life
activities. Research related to water and how to use water resources is an important issue. The
amount of fresh water available on earth is only about 25% of the total water. The aim of this
study is to identify potential aquifers with the geoelectric method. This can be a consideration
in determining the right location of the well in relation to efforts to obtain potential
groundwater resources to meet the needs of raw water, both in terms of quantity and quality.
The method used is a field survey by making observations including rock permeability
measurements, infiltration, laboratory and studio work. Field work also includes geoelectric
measurements, observations of groundwater levels and land use, and analysis of aquifers to
determine the location of drill points that have the potential to be developed. The results show
that the supply of raw water for a number of locations spread across Gunungkidul Regency is
very much needed, considering that in the dry season there is a shortage of water. Groundwater
conditions using the Schlumberger Method show that they have sufficient raw water potential,
but in terms of depth and discharge, each location is different from one another. Planning for
borehole construction is highly recommended, and planning is adjusted to the amount of
demand and availability of raw water.

1. INTRODUCTION
Water is a very important natural resource that is needed by
all living things in all their life activities. The amount of fresh
water available on earth is only about 25% of the total water.
The identification and management of groundwater quality is
critical to maintaining freshwater resources in arid and semiarid areas, it is essential for sustainable development [1].
Most of the water used for daily life for the community
comes from shallow/dug well water. This groundwater is
widely used by residents for various purposes with a well
depth generally between 1-25 meters. Free groundwater is still
the main source of clean water for most of the population in
meeting their daily needs. Its utilization is carried out by
making dug wells and pantek wells at a depth of less than 20
meters below the surface. The free groundwater reserves in
2015 during the winter season in Solo were only 1.34 billion
L and the groundwater was constrained at the same time
reaching 21 billion L. While the water needs of the residents
of Solo were 51 million L / day, so it is estimated that there
will be a well water crisis in 2020 [2]. There are many
challenges related to the water crisis, this is due to the
increasing population, pollution of water resources, errors in
managing resources, and imbalances in water use policies [3].
Groundwater as one of the potential raw water resources has
received a lot of attention in relation to meeting raw water
needs for domestic needs. As an effort to meet the needs of
raw water, especial
