Cement has hydraulic properties (mixed with water) will form a bond and harden. Cement-making materials consist of the main ingredients (Limestone, Iron Sand, Silica, and Clay) which are the ingredients in the manufacture of Rowmix in the Rowmill. In the main ingredient there is a magnetic mineral content for the manufacture of Component Compoun. To see changes in magnetic minerals from the cement manufacturing process, it is necessary to analyze the consistency of the material until the initial manufacture. The purpose of this study was to determine the consistency of the magnetic mineral as the main ingredient of cement in the Rowmix manufacturing process. The research method used is rock magnetism using a Bartington Susceptibility Meter Type B (MS2B) which can measure based on mass and volume with 2 different frequencies, namely Low Frequency and High Frequency. This measurement uses 6 different samples, namely the main ingredients of cement (Limestone, Irond Sand, Silica, Clay) and Rowmix materials (Rowmix 1 (RX1) and Rowmix 2 (RX2). From these measurements, the susceptibility values obtained from the main ingredients including Limestone approx. 23.7 x 10−8 m3/kg - 46.6 x 10−8 m3/kg, Irond Sand ranged from 470 x 10−8 m3/kg - 1791.1 x 10−8 m3/kg, Clay ranged from 852.7 x 10−8 m3/kg - 986.4 x 10−8 m3/kg, Silica ranges from 148.2 x 10−8 m3/kg - 166.9 x 10−8 m3/kg, while in Rowmill I process (Rx1) around 133, 4 x 10−8 m3/kg - 180.3 x 10−8 m3/kg, Rowmill 2 (Rx2) 133.4 x 10−8 m3/kg - 244.2 x 10−8 m3/kg, Magnetic susceptibility values in the main material range from 1532 x 10−8 m3/kg up to 2838,6 x 10−8 m3/kg, while the value of Rowmix 1 (RX1) and Rowmill 2 (Rx2) is lower than the magnetic susceptibility value of the main ingredient.

West Sumatera is a region that has an abundance of natural resources in the form of iron sand, one of which is in the area of Pasia Jambak Beach, Padang. Pasia Jambak Beach is one type of beach in rumps and sandy beaches, which has grayish-brown sand and rough grains on its surface. Iron sand could be formed due to weathering of rocks and materials found around the coast, such as old ships and others. This study aims to see the type rock of origin and the composition of the magnetic mineral elements found in the iron sand of Pasia Jambak Beach. The composition of iron sand-forming elements can be seen using XRF. The analysis results using XRF showed that the most dominant element in the samples was Si (Silica) and Fe (Ferrum). Based on the SiO2 vs K2O diagram, it can be seen that the iron sand in the Pasia jambak Beach area comes from weathering of Basalt, Dacite, and Latite rocks. So, it could be concluded that the original rock group from iron sand at Pasia Jambak Beach is the Calc-Alkaline group (medium Potassium content) and High K Calc-Alkaline (high Potassium content).

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.
