Item INTERPRETASI KUALITAS DAN KUANTITAS AIR BAWAH TANAH MENGGUNAKAN METODE GEOLISTRIK ATURAN SCHLUMBERGER DAN GEOKIMIA DI JALAN MANYAR SAKTI, KELURAHAN SIMPANG BARU, KECAMATAN BINA WIDYA, PEKANBARU, RIAU(Elfitra, 2022-01) Lubis, Miranda; M, JuandiSimpang Baru Village, Bina Widya District is an area that consists a lot of community housing. Community housing is one of the potential sources of domestic waste either in the from of liquid domestic waste from septic tanks, or solid waste from housing.the waste can infiltrate into the aquifer system, which can cause groundwater pollution. The method used in this research is a geoelectric survey with Schlumberger rule with two paths, while to determine the quality of groundwater, the geochemical method was used by analyzing the parameters of turbidity, pH, TDS, conductivity and salinity. The results obtained from geoelectric method show that the Manyar Sakti area based one the measurement results of the resistivity value at the research site is interpreted for path 1 the value of the soil layer rangers from 109,84 Ωm to 1,0 Ωm with a maximum depth of 40 meters. Track 2 has a resistivity value of the soil layer which ranging from 190,39 Ωm with 1,02 Ωm a maximum depth of 44,61 meters. While the value of chemical parameters, for the pH parameter test, all samples 𝐴 = 𝜋𝑟2 acidic and dangerous if consumed in excess. For the parameters of TDS, salinity, and turbidity are considered suitable to be used, while the conductivity parameters are on the threshold of the maximum conductivity of clean water.Item INTERPRETASI POTENSI AIR TAWAR DI DAERAH LAHAN GAMBUT STUDI KASUS DESA RIMBA PANJANG DENGAN MENGGUNAKAN METODE GEOLISTRIK SCHLUMBERGER(Elfitra, 2023-02) Sari, Chindy Kartika; M, JuandiLithology interpretation in Gean de Green II Housing, Rimba Panjang Village, Tambang Sub-district, Kampar Regency has been measured using Schlumberger geoelectric method. This study aims to determine the lithology layer and aquifer layer that has the potential for fresh water. The measurements are carried out in two trajectories with a length of 300 meters. Based on data processing, the resistivity value of the soil layer ranges from (11.42 - 1287.30) Ωm with a maximum depth of 42.10 meters. for layer 2, the resistivity value of the soil layer ranges from (10.23 - 62.28) Ωm with a maximum depth of 41.06 meters. The lithology below the ground surface of Gean de Green II Housing is peat, clay, sandstone, limestone, dry gravel, saturated gravel, passive clay and sand. The lithological layer that potentially contains fresh water or groundwater is a layer with a low resistivity value. In track 1 the depth is about (18.07 - 35.92) meters while in track 2 is (41.06 - 60.00) meters. The thickness of the peat layer affects the water quality. Shallow peat layers ( < 1.00) meters do not affect water quality while peat layers with a thickness of about (1.00 - 7.59) meters can affect water quality. The water are not suitable for consumption, because it is acidic and brownish red color and might cause rustItem MENENTUKAN LITOLOGI DAN AKUIFER MENGGUNAKAN METODE GEOLISTRIK KONFIGURASI WENNER DAN SCHLUMBERGER DI PERUMAHAN WADYA GRAHA I PEKANBARU(2013-06-10) Gokdi, Heri; Edisar, M.; M, JuandiA research has been conducted to determine lithology and aquifer position in Wadya Graha I Regency Delima Village Tampan Pekanbaru. Geoelectric 2-D Wenner and 1-D Schlumberger configuration methods have been used for the research. Resistivity measurement of was conducted at the location using resistivitymeter of Naniura type NRD 22 S. Data of this research was processed using software Resistivity 2-D Inversion (Res2Dinv) for 2-D Wenner and software Vertical Electrical Sounding (VES) for 1-D Schlumberger. The results yields lithology data that consists of four layer formations. Both methods shows the same results. Therefore, both methods can be used to determine lithology and aquifer layer of a location.Item PENENTUAN DISTRIBUSI DAN KUALITAS AIR BAWAH TANAH DENGAN MENGGUNAKAN METODE GEOLISTRIK SCHLUMBERGER DAN METODE GEOKIMIA DI DESA KUALU KECAMATAN TAMBANG KABUPATEN KAMPAR(Elfitra, 2022-01) Savitri, Mutiara Widya; M, JuandiThe distribution and quality of groundwater have been determined in Kualu Village, Tambang District, Kampar Regency. Underground water in research area has the potential for polluted water due to waste from septic tanks and solid waste from the housing. The waste can affect the suitability of the water for consumption, therefore, it can affect the aquifer system. This study aims to analyze the aquifer layer, distribution, and water quality of the groundwater. This research uses Schlumberger geoelectric and geochemical method. The data was collected from the field with two passes, each of which is 100 meters in length at MutiaraKualu III Housing with a resistivity device consisting of current and potential difference parameters. The data was converted into apparent resistivity using equations and processed using a software called Software Progress. The first sample has pH value of 4.08, turbidity level of 0.28 ppm, TDS of 18 mg/L, COD of 19 mg/L, and total Coliform value of 96/100 mL.while the second sample has pH value of 5.00 ppm, turbidity level of 1.52, TDS 21 mg/L, COD 32 mg/L, and total Coliform value of 27/100 mL. Based on the five parameters tested, it can show the feasibility of water for consumption.
