Abstract

The Lam Teuba Formation is one of the local fault areas of the Seulimuem segment located in the Grand Mosque sub-district of Aceh Besar regency. The Lam Teuba Formation has several types of rocks such as basaltic andesite lava, pyrolastic flows, pyroclastic falls, and sedimentary rocks, namely claystone, limestone sandstone, agglomerate, limestone. Rocks have physical characteristics, namely density and porosity which have different values in each rock. This difference can be caused by the minerals contained in the rock. The method used to calculate the density and porosity values used the Archimedes method, and the identification of mineral types using the infrared spectroscopy method. The results of data processing obtained the highest original density value at location 1 sample 1 with a value of 3.42 and the lowest value at location 5 sample 2. The highest dry density value was in location 1 of sample 1 with a value of 3.33 and the lowest value was in location 5 of sample 2. The highest saturation density value was in location 1 of sample 1 with a value of 3.43, the lowest value was in location 5 of sample 2 with a value of 2.07. The average porosity value was the highest with a value of 5.41 in the poor quality category in sample 4, while the lowest value was 4.62 in the very bad category in sample 1. The types of minerals found in the Lam Teuba formation are illite, montmorillonite, kaolinite minerals with a mixture of smectite which is a clay mineral group and siderite minerals which are carbonate mineral groups.

Abstract

The research aims to determine the distribution and concentration levels of CO and NO2 gases based on Sentinel-5P Satellite Image processing and UHI levels based on Landsat 8 Image processing during the implementation of Covid-19 Large-Scale Social Restrictions (PSBB) in Pekanbaru City. Data processing begins by extracting CO and NO2 gas data as well as Landsat 8 imagery via cloud computing on Google Earth Engine (GEE). The PSBB policy in Pekanbaru City came into effect in 2020. The PSBB policy will limit community activities, which will affect the concentration of CO and NO2 gases as well as UHI. The research results show that before the 2019 Covid-19 PSBB the respective concentrations of CO and NO2 gases were (CO: 4.16 x 10-3 mol/m2 – 4.70 x 10-3 mol/m2) and (NO2: 4, 16 x 10-5 mol/m2 – 5.68 x 10-5 mol/m2) with a UHI temperature of 34.23 0C. Then, when the PSBB was implemented in 2020, there was a decrease in the concentration of CO and NO2 gases to (CO: 2.87 x 10-3 mol/m2 – 3.20 x 10-3 mol/m2) and (NO2: 2.98 x 10-5 mol/m2 – 5.28 x 10-5 mol/m2) with the UHI temperature decreasing to 30.24 0C. However, CO and NO2 gas concentrations increased again after PSBB in 2021 to (CO: 2.90 x 10-3 mol/m2 – 3.31 x 10-3 mol/m2) and (NO2: 2.87 x 10-5 mol/m2 – 5.76 x 10-5 mol/m2) which was followed by an increase in the UHI temperature to 32.62 0C. Therefore, it is known that the concentration of CO and NO2 gases will affect UHI. If the concentration of CO and NO2 gas increases, the UHI temperature will also increase.
