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.

Abstract

This study aims to determine the Types of Magnetic Minerals in Bone River Sediments in the Mining Area of Tulabolo Village. The XRF test was used to identify Magnetic Mineral elements in Bone River Sediments, and electrical conductivity (EC), pH, and temperature parameters for in situ measurements of Bone River water samples and measures of mineral types was carried out on prepared sediment samples. The results showed that direct measurements on water samples showed that the values of EC, pH, and temperature were (1,620-1,900) µS/cm, (5-7), and (25.0-25.9)oC, respectively. While the results of measurements using XRF elements that have the most significant percentage are elements (Si), especially at the S10 point of 58.84% diamagnetic minerals, elements (Fe), especially at the S7 point of 22.80%, element (Al) at the S10 point of 8, 11%, elements (Ti) at point S1 1.84% which are ferromagnetic minerals. Elements (Ca) at end S2 of (2.67%), elements (K) at point S1 of 1.50% paramagnetic minerals.
