Abstract

Along with increasing human growth and activity, the need for clean water also continues to increase. Kemiri Village, Jabung Subdistrict, Malang often experiences clean water difficulties for daily needs, especially during the dry season. This study aims to determine the location of aquifers and potential groundwater discharge in Krisik Hamlet. The research method uses the Schlumberger Configuration Geoelectric Method and data analysis using IPI2WIN Software which is then smoothed using Progress 3 Software to identify aquifers and groundwater potential. Data acquisition was carried out on a 100-meter stretch of AB with 3 sounding points. Groundwater potential of the study area can be found at depths ranging from 0.04 - 44.71 meters bmt. The thickness of the aquifer layer ranges from 6.51 - 40.49 meters in the form of sandstone with resistivity values ranging from 164.69 - 248.84 Ωm. The type of aquifer found in the study area is unconfined aquifer in locations 1 and 2 and floating aquifer in location 3.

Abstract

Widas Subwatershed in Nganjuk Regency is a tributary of the Brantas Subwatershed that often experiences flooding during the rainy season. The data on flooding is still in the form of numbers and tables so it needs to be mapped. The presentation of data in the form of a map is needed so that readers can analyse its distribution and help in mitigation planning against flood disasters. The purpose of this research is to analyse the level of flood hazard in the Widas Subwatershed of Nganjuk Regency and present it in the form of a map. The method used was scoring of 6 flood parameters, namely slope, land elevation, soil type, rainfall, land use, and river density, then weighting with the Analytic Hierarchy Process (AHP) method. The result of this research is that Widas Sub Watershed of Nganjuk Regency is dominated by flood hazard area of 33,375.95 Ha while the flood hazard area is 3,415.55 Ha. Flood hazard areas are found in 28 villages in Gondang, Loceret, Nganjuk, Pare, Sukomoro, and Tanjunganom sub-districts. The flood-prone areas are caused by 4 main factors: low land elevation, Alluvial soil type, residential land use, and the density of the river is very sparse.
