“…Permeability, water retention, raindrop erosion resistance, strength, wind erosion resistance, durability, scanning electron microscopy (SEM), and X-ray diffraction (XRD) measurements were used to evaluate the cementation effect (Lai et al, 2021). The microstructure of treated and untreated sand samples was analyzed using scanning electron microscopy (SEM) and X-ray diffraction (XRD) to determine the presence of crystalline materials (Almajed et al, 2020) (Ardiani et al, 2020) (Yu et al, 2021) (Hadi et al, 2022). So that XRF and XRD assays can be used to examine natural materials.…”

In the Talang siring tour of the Pamekasan district, numerous illegal mining operations along the coast for sale and personal use produce building materials with low economic value. However, if the sand is processed further, it will produce materials with high technology utilization and economic value. This research is a preliminary investigation into converting sand into high-value minerals to be utilized economically. Using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) experiments, this study aims to determine the sand's mineral content in the Talang Siring tourist area in Pamekasan Regency. Initial identification is the XRF test function for analyzing sand's chemical elements and composition. The purpose of XRD is to analyze the crystal structure and correlate the results with Macth and origin software based on the XRF results. The results of the XRF test indicated that Silicone had the highest concentration of minerals at 63.8%, followed by Calcium at 29.4% and Iron at 2.45%. The XRD test results indicated that the sand's mineral composition was qualitatively SiO2 90%, CaCO3 8%, Iron 1%, and the remainder 1%.

“…The representative bacteria which form ureatype calcite is Bacillus pasteurii (alkaliphilic) (Bachmeier et al, 2002;Dikshit et al, 2022;Hadi et al, 2022), B. megaterium (Sun et al, 2019), B. simplex (Enyedi et al, 2020), B. sphaericus (Adzami et al, 2018). These bacteria express much amount of urease.…”

Several bacterial species have been found to involve the biomineralization phenomenon promoted by them. The formation of calcium carbonate mineral (calcification) is most abundant phenomena as biomineralization by bacteria. Here we introduce the simple assessing method of calcification catalyzed by thermophilic bacteria. To obtain the fresh biomass of thermophilic bacterium, the thermophilic bacteria was cultured on conventional nutrient agar medium at 60˚C. Fresh biomass of bacteria is simply placed on calcite promoting hydrogel surface, and incubated at 60˚C. After incubation for 24 to 72 h, a number of single crystals can be found in the biomass. This method provides simple assessing for screening of calcification upon thermophilic bacteria.
