SUMMARY
RABIAH, Student ID 2310246460, Interpretation of Groundwater Case Study in Harjosari Village, Sukajadi District, Pekanbaru City Using Geophysical and Geochemical Integration, supervised by Juandi, M and Ari Sulistyo Rini.
Groundwater plays a crucial role in supporting the basic needs of the community, ranging from consumption and sanitation to economic activities, especially for household and industrial purposes in rapidly growing urban areas, such as in Harjosari Village, Sukajadi District, Pekanbaru City. The increase in domestic activities in this area has the potential to cause groundwater pollution due to the infiltration of waste. This study aims to analyze the level of groundwater pollution by combining geoelectrical methods and geochemical analysis. The geoelectrical method is used to measure subsurface resistivity values and determine the spread pattern of contaminants, while the geochemical method analyzes water quality parameters such as pH, Total Dissolved Solids (TDS), conductivity, and turbidity. Based on the interpretation of geoelectrical data from the Schlumberger configuration, it was found that the aquifer layer begins at a depth of 13.72 meters. This layer consists of sand and gravel material with a resistivity value of 198.2 Ωm. This layer exhibits characteristics of porous and permeable rocks, allowing groundwater to be stored and flow well. The maximum depth of electrical current penetration in this measurement reaches 46.63 meters. According to the results of geoelectrical measurements using the Wenner configuration, it was found that the aquifer is located at a depth of 7.97 to 12 meters. This zone has resistivity values ranging from 86.3 to 262 Ωm and consists of sand and gravel rocks. The relatively high resistivity values indicate the presence of groundwater with good quality, as there are no significant indications of contamination or pollution. The analysis of water quality based on four tested parameters pH, turbidity, TDS, and conductivity of 10 samples shows that all samples resulted in relatively clean water conditions.
