Abstract

Maninjau Lake is a caldera lake located in Agam, West Sumatra. This lake was formed from the volcanic activity of Mount Maninjau Purba about 60,000 years ago. The volcanic material resulting from the eruption is scattered and deposited in various places, one of which is in lake sediments. Volcanic ash contains various types of elements, including heavy metal elements. This study aims to determine the composition and content of heavy metal in the sediments of Maninjau Lake. The sample analyzed was MNJ 18-41B with a core length of 440 mm, focusing on specimens 148 mm and 376 mm. The selection is a specimen based on the magnetic susceptibility value obtained from the measurement meter susceptibility of the MS2E. Specimen 148 has a value susceptibility low of 2.1 × 10-8 m3/kg, while the 376 specimens have the highest value of susceptibility, the highest 141 × 10-8 m3/kg. The content of sediment elements was determined using the results of X-Ray Fluorescence (XRF) measurements. The measurement results showed that the mineral-forming elements in the sediments of Lake Maninjau were dominated by Si, Fe, Rh, and Zr. In contrast, the highest heavy metal elements are Mn, Fe, Sr, and Rh. Based on the elemental composition and mineral oxide compounds in the sediments of Lake Maninjau derived from volcanic ash.DOI: 10.17977/um024v6i22021p068

Abstract

Pesisir Selatan is a district where population depends on agriculture such as lowland rice. The rice seeds used were IR66. Efforts to improve the quality of Paddy soils seeds are fertilizing with chemical fertilizers. Chemical fertilizers used are Urea, KCL and Phonska. Continuous and excessive use of fertilizers will cause a decrease in the level of soil fertility due to the reaction between fertilizer minerals and soil minerals which also affects the magnetic susceptibility value. Based on these problems, further research was carried out to see the difference in the magnetic susceptibility value of paddy soils to the use of chemical fertilizers using the rock magnetism method with magnetic susceptibility parameters. The results showed that the paddy soil before and after being planted with rice seeds using chemical fertilizers decreased and increased the value of magnetic susceptibility due to the reaction between mineral fertilizers and soil minerals and waterlogging during the cultivation process. Meanwhile, the paddy soil before and after planting rice seeds that did not use chemical fertilizers decreased the magnetic susceptibility value quite far due to the absence of other mineral additions in the paddy soil such as chemical fertilizers.
