“…Water that accumulates from high rainfall results in unbalanced cracks. If the cracks accumulate by water, it will be very dangerous because the load will get heavier below the surface which at any time can trigger landslides [9] . Three landslide susceptibility zones, namely low, high, and very high landslide susceptibility, have been described, landslide zones that result in very high landslide vulnerability due to rainfall [16] .…”

Landslide zone investigation has been conducted using geoelectricity to determine the number of cracks and using a compressive strength test to determine compressive strength cracks. The result of this research is that the rock layers of Waru District consist of soil layers resulting from the weathering of quartz rock into quartz sandstone. This quartz sandstone lies on top of a more solid rock layer. The type of landslide that is formed in the Waru sub-district is translational. This type of landslide is caused by water entering the lower layer, causing landslides and the number of cracks that trigger landslides. The results of the low compressive strength test resulted in landslides. This result was due to a decrease in the number of pores filled with water and an increase in the pores that were not filled with water. This occurs due to the presence of water in the cracks, the number of cracks cavities, and the density of the cracks which results in reduced adhesion between the cracks holding layers.

“…XRF results of Waru 3 Si 43.3%, Waru 2 Ca 71.37%, Waru 1 Si 58.3%, XRD results in Waru 3 is composed of 75.2% CaCo3, while Waru 2 and Waru 1 are composed of 88% SiO2 (S. V. Ariyanto & Joni, 2019). This research is still focused on landslides using XRD and XRF tests, not on minerals that can be used as production materials, and the tested material is non-sand soil.…”

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%.

“…Meanwhile, during the rainy season, water can enter to fill the cracks.The location of the cracks has the possibility of landslides. The more cracks in the subsurface, the greater possibility of landslides [20]. Clay is impermeable, so the water that enters was trapped cannot be escaped by the clay.…”

Landslides can be occurred in almost every natural slope or artificial slope slowly or suddenly with or without any prior signs. The main reason for slope collapse is the increase in shear stress in the landslide, the decrease in shear strength, or both. Landslide problems can result in loss of life and property, damage to the environment, infrastructure, public facilities, and disrupt livelihood generally. Landslides can be detected by exploration of the subsurface. The geoelectrical method is one of the geophysical methods to know the change of resistance of a type of rock layer below ground level. The research aims to interpret the lithology of the subsurface in the Candi Industrial Area, Ngaliyan, Semarang using Schlumberger configuration. The results of measurements are voltage and electric current to calculate the apparent resistivity value processed by IP2Win software to determine the lithology and the slip surface area. The results present that lithology in the research area consists of sand clay, clay, and sandstone. The results showed that the locations of landslide-prone areas lie at the contact between sand clay and clay with that area at a depth of between 19.95 – 31.62 m there is one difference in the resistivity value which can be assumed to be a slip surface.The result of the research can be used to make policy rules of landslide mitigation.
