The Geoelectric Resistivity Methods to Determine the Presence or Position of Layers and the Aquifer Type in Transition and Inland Tropical Peatlands of Central Kalimantan, Indonesia

The decreasing groundwater level (GWL) in degraded tropical peatland areas during the dry season has been one source of annual peat fire disasters Central Kalimantan. After severe 2015, Peatland Restoration Agency's strategies' restoration efforts enhance moisture and increase hundreds deep wells canal blocking burned area 2015. This study examines use geoelectric resistivity methods determining attachment or position layers types aquifers transition inland peatland. research was conducted on transitional peatlands Sidodadi Village with 19 estimate points geoelectric, nine swamp Taruna Jaya Village, 18 Kalampangan Village. used quantitative approach is a one-dimensional (1 D) which using Schlumberger array. While qualitative process verified result sequences observation two drill Sidodadi, Jaya, hand Kalampangan, geological stratigraphy. results obtained 4 (four) composition resistivities ranging from 1.224 - 661.1 Ωm 3.37 – 7,950 5.36 16719 Ωm. data field verification interpretation show that soil/lithology layer consists layers: peat, sand, sandy clay, clay. type aquifer an unconfined aquifer.
