    ANALISA AIR TANAH DAN HIDROGEOKIMIA MENGGUNAKAN METODE GEOLISTRIK KONFIGURASI SCHLUMBERGER DI JALAN MATOA RAYA SIDOMULYO BARAT KECAMATAN TAMPAN
    (2020-09) Manalu, Lely Saskia; Krisman, Krisman
    This research of Underground Water and Hydrogeochemistry has been done sorrounding the Street Matoa Raya West Sidomulyo, Tampan District using the Geoelectric Method Schlumberger Configuration and water quality test at UPT Health and Environment Laboratory of Riau Province. This research was aimed to identify the subsurface lithology based on resistivity values of rocks in the research area. The number of trajectories were two points with a stretch of 150 m. Geoelectric data processing was done using Microsoft Excel and Progress Software. In the trajectories I the resistivity values range from 181.59-652.54 ohm-m. The lithology of trajectories I consists of gravel, gravel sand, alluvial and sand. In the trajectories 2 resistivity values range from 272.23-1727.52 ohm-m. The lithology of trajectories 2 consists of sandy silt, gravel sand, gabbro. Water quality test using pH parameter shows that the water is acidic (pH<7). Total Dissolved Solid (TDS) levels in the sample were below the drinking water quality threshold, which is<500 mg/l.

    INTERPRETASI AIR BAWAH TANAH BERDASARKAN PENCITRAAN GEOLISTRIK KONFIGURASI SCHULUMBERGER SERTA HIDROGEOKIMIA STUDI KASUS DI PASAR TARAI BANGUN
    (perpustakaan UR, 2021-07) Krisman, Krisman; Ma’mun, Sukron
    Interpretation of underground water based on the geoelectrical imaging and hydrogeochemical case study in Tarai Bangun market has been carried out. This research was done due to potential market waste that can contaminate groundwater quality. The depth of aquifer can be determined using the Schlumberger configuration geoelectric based on the two tracks in which each track has a length of 100 m. The results for four layers with different resistivity, underground water is found in the fourth layer. Underground water was collected from residents well water in the research area. This underground water sample was tested for some parameters such as pH, TDS, Pb, and Zn. Based on the obtained parameters of underground water, it is found that the underground water in this research area cannot be consumed because the pH obtained at a distance of 5 meters from the market is > 9.0 or alkaline. The pH of this underground water is bigger than the pH mention in the Regulation of the Minister of Health of the Republic of Indonesia Number 32 Year 2017. This underground water needs to be further processed so that the underground water can be consumed by residents in the research area.

    METODE GEOLISTRIK KONFIGURASI WENNER DAN HIDROGEOKIMIA SEBAGAI IDENTIFIKASI AIR TANAH DANGKAL
    (2020-10) Agustin, Putri; Krisman, Krisman
    Water is the main requirement for human life. Therefore, a research was conducted to estimate groundwater potential using the Wenner Configuration Geoelectric Method on JalanMatoa Raya Sidomulyo Barat with coordinates N 0˚26'30,19214 '' and E 101˚24'20,3602 ''.The track used is 2 tracks with a path length of 100 meters and a space between the electrodes of 4 meters on each track. Then the data obtained were processed using Res2Dinv version 3.54.44 software. The results showed that the resistivity values varied around 360Ωm - 4839Ωm on track 1. The lithology of line 1 consisted of sand, gravel, sandstone, dry gravel and loam / marl. Line 2 for the resistivity value ranges from 243Ωm - 7769Ωm. Path lithology 2 consists of groundwater, gravel, sand, loam / marl, sandstone and dry gravel. The water quality test based on pH parameters shows that the water is acidic (pH<7), while based on the turbidity in the sample it is 0.00 which means that the water is not cloudy or clear.

    PREDIKSI KEDALAMAN AKUIFER DAN KUALITAS AIR TANAH DENGAN MENGGUNAAN METODE GEOLISTRIK KONFIGURASI WENNER DI KELURAHAN DELIMA KECAMATAN BINAWIDYA KOTA PEKANBARU
    (perpustakaan UR, 2021-07) Rabi’ah, Rabi’ah; Krisman, Krisman
    The condition of an inundated and non inundated area is influenced by geology of a particular area. This will affect the condition of the aquifer layer. This research aims to identify the groundwater aquifer layers and quality. Measurements was conducted in Delima Village, Binawidya Distric using the Wenner configuration geoelectric method on two tracks with different geological conditions, which are inundated and not inundated with a measurement distance from the starting point of approximately 150 meters and 100 meters. The analyzed parameters for groundwater quality tests are pH, Turbidity, TDS, COD and Total Coliform. Based on the result of data processing for the first track the aquifer layer is at a depth of 9,26-15,9 meters and a thickness of 6,6 meters with a resistivity value of 22,8-267 Ωm. The second aquifer track is found at a depth of 7,46-9,56 meters and a thickness of 2,1 meters with a resistivity value of 49,3-299 Ωm. Based on the result of soil Physics analysis, the permeability show that the Litology of the subsurface layers is dominated by sandstone layers with the value of 6,01-6,04 cm/hour. All analyzed water samples is still meet the requirements for clean water quality except water quality of total coliform bacterial parameters from the sample track 2 which exceeds clean water quality standards.

    RANCANG BANGUN ALAT TEKNOLOGI PENGERING PAKAIAN DENGAN MEMANFAATKAN LIMBAH BIOMASSA ARANG TEMPURUNG KELAPA BERBASIS ARDUINO UNO
    (Elfitra, 2023-07) Saputra, Dhery; Krisman, Krisman; Muhammad, Juandi
    Research has been carried out on "Design of a Clothes Dryer Technology Tool by Utilizing Waste Coconut Shell Charcoal Based on Arduino UNO" using an experimental method. This Arduino UNO-based clothes dryer technology uses biomass energy from coconut shell charcoal which is used as an energy source by using the mass of biomass used, namely 1400 grams for thin clothes and 4000 grams for thick clothes. Measurement of temperature in the drying chamber using the DHT22 sensor with an observer time interval of 10 minutes. The results of the research data obtained using a mass of 1400 grams of coconut shell charcoal for this type of thin clothing reached the highest source temperature and temperature in the drying chamber respectively 71.00 °C and 69.00 °C, while for a mass of 4000 grams of shell charcoal coconut with thick clothes, namely 106 °C and 93.40 °C. This happens because the energy produced by the biomass works to transfer heat from the source to the drying chamber, so that the temperature value of the source of the biomass combustion chamber is higher than the temperature in the drying chamber and the temperature resistance of the drying chamber lasts for 200 minutes.
