Abstract

Khalid Bin Walid Islamic Boarding School is one of the Islamic boarding schools in Rokan Hulu Regency. This school is located in a water crisis area with complex groundwater sources. This study aims to determine the potential of groundwater as a reference for drilling wells and to determine the structure of the subsurface layer by using the geoelectrical method. The geoelectrical method is a method that is widely used, and the results are promising, namely, to obtain an overview of the subsurface soil layers and the possibility of groundwater presence. The configuration used in this study is the Schlumberger configuration using the basic principle of current propagating in the earth when injected in all directions and the assumption that the potential of the subsurface rock layer is the same. Data will be collected on four tracks, with a track length of 100-200 m. From the data processing results, it was found that potential sources of groundwater on track 3 with a depth of 13.7–30.3 m with alluvium rocks were suspected. Groundwater on this track can be used as a source of clean water using drilling.

Abstract

This study aims to determine how much the maximum vertical displacement of vibrations experienced by the bridge when something passes over it and compare it with the complete removal permitted by SNI 03 – 2847 – 2002. To find out the direction of movement of vibration particles when a vehicle/something crosses the bridge. The maximum vertical displacement value of bridge vibration due to vehicle load experimentally ranges from 8.5 mm – 29.2 mm and theoretically from 127.5 mm – 170 mm. This value (experimentally) is smaller than the results obtained in theory, which means that the bridge structure can still withstand the instantaneous external loads that cross the bridge. At the same time, the direction of movement of the bridge particles passed by vehicles is generally vertical to the direction of the bridge.

Abstract

This scientific work aims to determine the value of vehicle amplification. Data processing uses Geopsy software with HVSR analysis, and the analysis results produce amplification values. From the results of the discussion, it can be concluded that for areas where landslides have not occurred, locations I, II, and V. Location I with low soil classification, the amplification value of each truck vehicle is 2.52, car 2.63, and motorcycle 2.26. In location II, where landslides have not yet occurred, the medium soil classification is for trucks with an amplification value of 3.47. In contrast, the low classification for cars and motorcycles has an amplification value of 2.73 and 2.77, respectively. For location V, which is far from the main road, the amplification value of 4.26 is included in the medium soil classification. Meanwhile, landslides have occurred in locations III, IV, and VI. Locations III, IV, and VI are where landslides have occurred with moderate and high soil classifications. Location III is included in the moderate classification with an amplification value of 4.08 for trucks, 4.37 for cars and 4.38 for motorbikes.

Abstract

An analysis of soil chemical elements using X-Ray Fluorescence (XRF) has been conducted on paddy fields in Dutulanaa Village, Gorontalo Regency, and corn farms in Polohungo Village, Gorontalo Regency. Soil samples were taken at three locations, namely corn location 1 (location I), corn location 2 (location II), and paddy fields (location III). At each location, samples were taken at 2 points to obtain 6 pieces. The distance between sampling points is 10 m. Based on the results of XRF measurements, the elements that dominate in paddy fields and corn include silica (Si), iron (Fe), aluminum (Al), calcium (Ca), titanium (Ti), potassium (K), and manganese (Mn), where Si is a diamagnetic element, Fe is a ferromagnetic element, and Al, Ca, Ti, and K are paramagnetic elements. The most significant percentage is silica (Si), 60.27% in corn soil 2 points J2T2. The next highest element is iron (Fe), 29.47% in corn soil, 1 point J1T2. The next element is aluminum (Al), 9.10% in corn soil at 1 point J1T1, calcium (Ca) in corn soil at 2 points J2T2 is 10.03 %, titanium (Ti) was 2.31% in paddy fields at ST5 point and potassium (K) was 2.31% in a paddy field at ST5 point, and the lowest value was manganese (Mn) of 0.59% in corn soil 2 points J2T1. Even some heavy metal elements, such as lead (Pb), were found—zinc (Zn) and manganese (Mn). The highest heavy metal elements were found in agricultural corn land at 2 J2T2 points, namely lead (Pb) at 158 ppm, zinc (Zn) at 4,555 ppm, and manganese (Mn) at 17,100 ppm, where these results have exceeded the threshold of soil quality standards, resulting in environmental pollution of agricultural land.
